State both sides and ask before changing product semantics. + +## Architectural invariants + +- JIN Core Engine is a model-agnostic cognitive runtime, not a chatbot skin and not a framework tied to one LLM. +- The normal model path is direct: user turn -> `AgentRuntime` -> `BrainNode`. Do not add a pre-Brain routing framework without an explicit task. +- Brain is the only foreground response route. `BrainNode` must resolve the canonical `brain` runtime/client; Service must never become a foreground response mode through `SERVICE_CONFIGURED`, model availability, or a legacy flag. +- Service is a logical background role. If no dedicated `SERVICE_API_BASE` is configured, `clients/registry.py` intentionally aliases the Service client to the Brain client; a dedicated Service endpoint changes only background execution. +- `USE_SERVICE_AS_BRAIN` is legacy config input only. `config_loader.py` may migrate it once and then removes the attribute from normalized config; launcher detection exists only to preserve old local configs during startup. Archived `SERVICE` roles/`RUNTIME_MODE=SERVICE` and the logger's old Service-output presentation are reader compatibility, not live routing. +- `RuntimeContext` is the in-process live state hub for a runtime session. Do not create parallel sources of truth for state it already owns. +- L2 and L3 are **removed architectural layers**. Do not restore them from old README/tests/indexes. Any surviving L2/L3 names must be classified as compatibility, stale tests/docs, UI residue, or dead legacy before touching them. +- Durable facts belong in L-T. FRAME is live operational memory; do not reintroduce a durable FRAME/L2/L3 hierarchy. +- Active Memory, Delayed Memory, L-T facts, persistent Files, live FRAME memory, and session/bootstrap state are different systems with different lifetimes. LOGS is a disk archive projection, not another memory layer. Do not collapse them into one generic memory store. +- Session continuity must distinguish a real USER move, a completed turn, an interrupted USER-only turn, an action-only completion, and a blank bootstrap tab. A real USER row can become the newest conversation move without a visible JIN row; a blank tab cannot. +- Bootstrap lifecycle is owner-locked: greeting only + close is not a saved session; any real USER send makes it saveable, including Stop before/after that send. A completed USER turn restores USER then its own JIN/reasoning, with one divider after the source session, never inside the pair. See D049 in `docs/JIN_DECISIONS.md`; do not change this flow or re-pair unrelated turns to hide corrupt logs. +- Normal continuation is disk-owned: JSONL dialogue/actions/tool checkpoints plus the latest saved `logs/.../frames` snapshot; Active/Delayed/L-T/Facts retain their existing disk owners. Browser cognitive storage is a page-local projection and must never hydrate the server or choose a source session (D057). The retired durable `jin.sessionCheckpoint.v2` browser value is cleared at page startup rather than used for reload continuity. +- Soft reconnect reuses the live server `RuntimeContext`. After backend restart, restore from disk again; never import `runtime_resume` contents. Explicit archive checkout sends only a source ID, which the server resolves again. +- A missing/deleted archive cannot be replaced by browser contents. Blank/greeting-only tabs cannot become continuation owners; the newest surviving real USER move owns normal bootstrap. +- Session CLEAR persists `logs/.continuation-cleared.json`, a disk barrier recording USER row counts. Passive completions/actions cannot lift it; a new real USER row can. Explicit archived restore remains available. +- Keep session lineage and original snapshot timestamps. Explicitly empty disk FRAME/tool results are authoritative; never revive them from a stale prompt or browser cache. +- Session-action history is structured continuity data. Preserve supported part metadata across persistence/bootstrap (for example JIN_COLOR `parts[].colors`), not only the visible action text. +- JIN color belongs to server `RuntimeContext` and its disk checkpoint/actions. Browser room state is only a projection; it never outranks disk on reload. +- Ordinary Brain turns include the previous successful reasoning block. Its projection keeps both edges and may replace only the middle with an explicit `CUTTED N chars` separator; action/recovery follow-ups build their own reasoning context and must not duplicate the ordinary block. +- `` is bounded by the newest five pairs, not by a per-message character cap. Preserve each selected USER/JIN message in full; normalize physical newlines to literal `\\n` without silently truncating content. +- Archived restore intentionally stages historical resources and replays them through the real action path after the one-shot restore response. Do not add a second late apply path. +- Anonymous/shadow mode may read global durable context but must not silently perform restricted persistent writes. + +## Runtime actions + +- `contracts/*.json` are the canonical model-facing contracts for concrete action schemas and action-specific rules. Every concrete contract keeps its human-readable `schema` lines before `rules`; failed action results reuse that schema instead of inventing a second error-format contract. +- Failed runtime actions are not completion. Render their tool result as readable text (status/reason, supplied payload when relevant, and the correct action schema), then use the shared failure follow-up so Brain continues from the failure rather than assuming the mutation happened. +- Keep `rules/runtime.py` for cross-action sequencing/loop invariants, not duplicated field-by-field action instructions. +- Every new action needs: contract -> parser/normalization -> guard if needed -> dispatcher/handler -> emitted state/result -> tests. +- Runtime action execution is source-ordered. For each emitted call, finish `prepare -> run` before touching the next call. Contract `runtime_order` orders model-facing instruction assembly only; do not reintroduce action stages, a visual collector, or another execution-priority layer. +- Streaming can split markers at arbitrary chunk boundaries. Always test complete, split, repeated, incomplete, false-prefix, and flush/stop cases. +- Do not let executable private action markers leak into visible answer text. A marker immediately preceded by an opening quote/backtick/bracket is a literal example: keep it visible and do not execute it, including across stream chunk boundaries. +- Canonical `JIN_COLOR` and `JIN_SIZE` syntax is paired XML with the payload in the body: ` #00f2ff ` and ` w:120 h:120 `. Inline/colon forms are localized legacy compatibility only. Marker removal must preserve ordinary visible text on both sides of the marker. +- `JIN_SIZE` accepts positive decimal `px`, `vw`, `vh`, and `%` values; unitless values mean `px`. Preserve relative units through parsing/events and resolve them against the live browser viewport only when applying the action. `%` is axis-relative (width -> viewport width, height -> viewport height); `vw` and `vh` always use their named viewport axis. Persist the resulting rendered room geometry in pixels. +- JIN visual markers are ordinary source-ordered runtime actions, not a special collected sequence. Drop only a true no-op repetition in the same runtime-message scope; preserve alternation such as red -> blue -> red and allow the same color again in a later message. +- `JIN_REACTION` canonical syntax is paired XML with one emoji: ` ๐Ÿ˜‚ `. The older colon form is compatibility only. +- Skill loading is model-facing ` skill1, skill2 ` and unloading is ` skill1, skill2 `; each comma-separated list expands to ordered internal `LOAD_SKILL`/`UNLOAD_SKILL` actions. +- MCP integrations live behind the one generic `CALL_MCP` action. Expose it only when a loaded skill has a valid canonical `...` declaration; keep semantic guidance in the skill and live tool names/input schemas in the discovered `` block. Preserve one MCP connection per loaded skill across follow-ups, never reuse cached MCP call results, and hydrate returned MCP images into the normal pinned-file/next-follow-up attachment path. +- Do not emit the same action twice because two parser paths recognized the same marker. +- Current Delayed save contract is `` with a JSON body. The old `` key/value format is legacy only. +- Current Active create/update model boundary is one flat structured JSON contract: `SAVE_ACTIVE_MEMORY`. If root `id` is present, the existing record with that exact `AM-xxxxxx` id is updated; without `id`, a new record is created. Create requires `conditions` and may add up to three custom root fields. Update uses the remaining root fields as changes; `conditions` may always change, while custom fields must already exist. Plain prose such as a trailing `(field: value)` remains conditions, not schema. Old `UPDATE_ACTIVE_MEMORY` markers and payload shapes are not accepted by the current Active Memory write parser. +- Search actions are effective only when the configured provider is actually available (`settings.CAN_SEARCH`). Feature flags alone must not expose `WEB_SEARCH`/`DEEP_WEB_SEARCH`; do not invent client-side API-key shape regexes when the provider has no stable key-shape contract. +- `CLEAN_TOOL_RESULTS` is a paired block. ` T1, T2, T3 ` removes one or more modern results by exact comma-separated IDs, atomically; an empty `` block clears everything, including legacy ID-less results. Unknown/malformed IDs fail without clearing anything. The old bare and `` forms are not executable. +- `BRAIN_MAX_FOLLOWUPS=0` means unlimited executable workflow follow-ups. A positive cap ends executable follow-ups at that count and then runs one final response tick with runtime actions disabled. Malformed-action recovery has one separate repair tick outside that ordinary budget; a second malformed attempt stops the repair loop and uses the same final non-executable response path. +- `SAVE_SESSION` is not a current runtime-action contract in this snapshot. Treat old references as legacy/session-restore compatibility until proven otherwise. + +## UI / visual language + +Before introducing any visual state, find and reuse the closest existing JIN UI primitive. + +- Do not invent new highlight colors, glows, banners, badges, icons, gradients, or interaction patterns without explicit owner approval. +- Reuse existing DOM structure, CSS variables, typography, radius, spacing, animation, and semantic states whenever possible. +- Color already carries runtime meaning. A new decorative color is not harmless. +- Loaded context, mere ID reference, pin state, pause state, inspect/modal open, and delete/restore are different semantics. Do not map all of them to one generic `highlight()` call. +- For UI fixes, verify the actual rendered DOM/event path, not only data/state mutation. +- Bubble skins are `dark`, `light`, and `bamboo`. Normal theme defaults to dark and Win95 to light; a user-selected skin that differs from the theme default is pinned across theme changes. Preserve `jin_bubble_skin` / `jin_bubble_skin_pinned` semantics. +- Live Avatar scaffold rings do not rotate. Scaffold rings/rays use the same context-pressure color as the context meter; ray peak opacity scales from about 0.10 to 0.70 with pressure and breathes to zero on a 30-second cycle. Center hide must include scaffold, runtime/memory rings, file ring/dots, and center rings, then enter dormant mode after the 420 ms fade so hidden animations stop. +- For bootstrap/restore visual fixes, locate every writer and prove there is one authoritative final apply path. +- Normal bootstrap renders at most the five newest real USER moves with their JIN/reasoning when present, followed by a divider dated to the last message in that source session (JIN completion, otherwise USER; omit it when timestamps are unavailable). Preserve USER-only interrupted/action-only moves without manufacturing an empty JIN bubble, and do not duplicate this tail during explicit archived restore. +- The first bootstrap color transition is the one 2-second transition; ordinary/live color changes use the shared 333 ms avatar-and-scene transition. Do not restore an old tint queue or add a second transition writer. +- Session-action interruption telemetry is causal UI state: validator/reasoning loops and context/output-limit recovery entries must be recorded/emitted when detected, before automatic follow-up/recovery starts. +- L-T rows use a short default preview (currently 50 characters), but a fact that is bubbled by reference/citation/context-loaded state must show its full value rather than a truncated citation. +- L-T facts absorbed by Delayed reports are hidden in the default active view unless context-loaded; the L-T counter toggles `show all` / `show active`. Keep normal fact sorting in both modes, and keep report-linked fact IDs opening the existing Delayed report modal. +- Memory inspector editing is value-only: double-click opens the existing hover card as an editor; FRAME edits only the latest frame value, Active edits conditions/value while preserving metadata/custom fields, and L-T edits only the fact value. Keys/IDs are not editable. Drafts remain page-local until the checkmark succeeds; rollback restores the last acknowledged value. +- Active and L-T explicit edits must surface the server `updated_at` immediately. Active pause/resume writes must synchronize the canonical Active store before later edits so a UI status change cannot be overwritten by stale backend state. +- FRAME values follow the detected language of the current user message while FRAME keys remain structural English `snake_case`; do not turn localized values into localized keys. +- Composer attachment chips are projections of already-pinned persistent files: click opens the existing preview, hold detaches from the message/context, and detach must not delete the persistent file or auto-expand Console. +- The panel has six navigation tabs: the five memory views `FRAME`, `ACTIVE`, `DELAYED`, `L-T`, `FILES`, plus `LOGS`. `session_title` is a protected FRAME field and is the archive title source. LOGS short-click opens restore in a new tab; the shared 1500 ms hold/delete interaction removes only that saved disk archive and may remove its now-empty date directory. Never let a still-open writer resurrect a deleted archive. +- Completed assistant output uses the explicit `Copy all` control under the avatar/message shell. Do not restore invisible bubble double-click/long-hold copy-or-retry gesture zones; answer rating remains release-gated off. +- Live Avatar L-T facts fan out in batches of 100 over additional outer lanes. Keep Active Memory between the outermost L-T lane and the file ring, and reuse the existing memory-row hover zoom/reference highlighting rather than adding a competing ring effect. +- Hover/detail metadata must survive non-semantic refreshes: counter-only runtime-action updates and bootstrap normalization must not silently erase tooltip/swatch data. +- Do not add `backdrop-filter`/blur or new translucent effects casually. Existing shadow/tint depth is deliberate. + +## Change discipline + +- Respect the requested scope. If asked to analyze only, do not edit. +- Prefer the smallest coherent fix over architectural tourism. +- Do not duplicate an existing listener, timer, writer, parser, storage path, or style primitive just to make a symptom disappear. +- Do not mass-format files or change line endings for a narrow fix. +- Do not add dependencies without a concrete need. +- Preserve existing user changes. Do not overwrite unrelated dirty work. +- Compatibility belongs in a localized adapter, not scattered across runtime/UI/rules. +- Do not guess IDs, state owners, ordering, or root causes. + +## Required investigation before a patch + +Trace the affected flow through all relevant stages: + +`source -> normalization -> canonical owner -> persistence -> bootstrap/restore -> prompt/action path -> emitted event -> UI projection -> tests` + +For stateful bugs, find **all readers and all writers**.

For runtime actions, find every parser and dispatcher path that can emit the same action. + +## Verification + +At minimum, run the checks that apply to the change: + +- syntax/import check; +- targeted unit/client-contract tests; +- `git diff --check` when git metadata is available; +- targeted search for the removed/renamed format; +- duplicate writer/listener/timer search; +- serialize -> reload -> hydrate round trip for restore/state changes; +- explicit-empty-vs-missing tests for disk bootstrap fields, plus page-local projection timestamp/lineage invariance for field-only cleanup; +- blank-tab vs completed vs interrupted USER-only vs action-only latest-session selection, separately for normal and anonymous log roots; +- dialogue-tail freshness independent of runtime `saved_at`, disk-source selection after physical deletion, write-failure preservation, and the disk USER-count clear barrier across multiple tabs; +- structured session-action metadata round trip (including JIN_COLOR swatch/hex hover); +- JIN_COLOR server-context -> raw runtime log/checkpoint event -> disk bootstrap -> one `session_actions_update` reconciliation round trip, including physical-reload and stale-source replacement; +- full-text recent-message context tests beyond the former character cap, including physical-newline escaping and the five-pair limit; +- ordinary-turn previous-reasoning inclusion and middle-crop tests, plus absence of duplicate ordinary reasoning in action/recovery follow-ups; +- chunk-boundary tests for stream/action parsing; +- legacy-record + modern-record tests for compatibility/timestamps; +- real DOM/render-path check for UI behavior; +- search capability tests with configured/blank/placeholder provider credentials when touching search contracts or prompt exposure; +- patch apply check against the exact source snapshot when delivering `.patch`. + +Do not claim the repository is green unless the relevant tests actually pass.

A full render replaces the old SVG, but state-only changes are deliberately synchronized in place where possible so a pin/load transition does not unnecessarily reshuffle or restart visual geometry. + +The SVG is intentionally only the visual projection. Rich matching/link payload (`citationIdentity`, citation key/text, reference aliases, delayed/L-T relation ids, file links, and the L-T archive angle) lives in the private `avatarNodeState` `WeakMap` in `runtime-avatar.js`, not in `data-*` attributes.

Its circles stay static (they do not rotate), while both circles and rays now mirror the same context-pressure color used by the Brain context meter. + +It is drawn by: + +```js +appendStaticScaffold(svg, overallColor, currentCenterColor, diffPercent, random, avatarLayout) +``` + +`diffPercent` remains in the function signature because the scaffold is built from the same render path, but it no longer drives scaffold-ray intensity. `getContextPressureRatio()` reads `--jin-context-pressure-percent`, which `runtime-panel.js` keeps synchronized with the Brain context bar. + +Current behavior: + +- scaffold circles are faint, structural, and non-rotating; their stroke uses `--jin-context-pressure-color`; +- the context meter maps 0..100% to HSL hue 150..15 (`68%` saturation, `64%` lightness), so scaffold color shifts with the same green-to-warm pressure gradient; +- there are `16` radial rays; pressure raises the stronger seeded subset from `3` toward `7`; +- `buildRayOpacityProfile()` sets unmultiplied peak opacity to `0.10 + pressure * 0.40`; each ray then applies a local strength (`0.60..1.00` for stronger rays, `0.12..0.44` for weaker rays); +- every ray uses a fixed `30s` cycle with a seeded phase offset; the CSS keyframes reach opacity `0` at both ends, so rays genuinely disappear and reappear rather than merely pulsing around a nonzero floor; +- ray stroke also uses `--jin-context-pressure-color`; the JS-computed ray color remains only the fallback/custom variable underneath it; +- `prefers-reduced-motion` disables the breathing animation. + +Change these when you want the background to feel denser, cleaner, brighter, or more technical: + +| Visual part | Where | +|---|---| +| Concentric scaffold circles | `STATIC_SCAFFOLD_BASE_RADII` / resolved `avatarLayout.scaffoldRadii` | +| Radial guide line range | `STATIC_RADIAL_LINE_INNER_RADIUS`, `STATIC_RADIAL_LINE_OUTER_RADIUS` / resolved avatar layout | +| Context pressure color/percent | `getContextPressureColor()`, `syncAvatarContextPressure()` in `runtime-panel.js` | +| Number/strong subset of rays | `rayCount`, `activeRayCount` in `appendStaticScaffold()` | +| Pressure opacity curve | `getContextPressureRatio()`, `buildRayOpacityProfile()` | +| Ray duration/phase | `appendStaticScaffold()` (`30s`) | +| Breathing curve | `.jin-avatar-scaffold-ray.is-jin-avatar-ray-breathing`, `@keyframes jin-avatar-scaffold-ray-breathe` in `runtime-avatar.css` | + +The inner scaffold/ring geometry is globally compressed with `INNER_RING_SCALE = 0.90`. The SVG itself also renders at `transform: scale(0.90)` so the new outer file perimeter has breathing room inside the square avatar shell. + +## Runtime Rings + +Runtime rings are the inner moving orbits. They are tied to the current runtime memory snapshot. Each visible runtime memory line becomes one ring. + +These rings are the most "alive" part of the avatar: they change radius, speed, color, dash texture, and decoration based on current runtime memory. + +### Runtime Ring Meaning + +| Visual signal | Meaning | +|---|---| +| Number of rings | Number of runtime memory lines | +| Ring radius | Source order in the runtime snapshot: earlier lines sit farther out, later lines move inward | +| Ring speed | Snapshot diff intensity | +| Ring direction | Seeded random direction | +| Ring color | Keyword palette plus emotional/alert influence | +| Runtime highlight glow | Uses that ring's current color rather than a fixed generic glow | +| Vertical stripes | The runtime **value** contains `?` or `!` | +| Filled change marker | The line was added in the last real runtime transition | +| Hollow change marker | The line changed in the last real runtime transition | +| Change marker size | Magnitude of the line change | + +### Runtime Ring Controls + +| Change | File | Exact place | +|---|---|---| +| Inner/outer radius range | `runtime-avatar.js` | `MIN_RING_RADIUS`, `MAX_RING_RADIUS` | +| How radius is calculated | `runtime-avatar.js` | `computeRingRecords()` | +| Speed | `runtime-avatar.js` | `appendOrbit()` -> `baseSpeed`, `effectiveSpeed`, `duration` | +| Dash texture | `runtime-avatar.js` | `appendOrbit()` -> `dashLength`, `gapLength`, `strokeWidth` | +| Arc fragments | `runtime-avatar.js` | `appendOrbit()` -> `arcCount`, `appendArcCircle()` | +| Punctuation-triggered stripes | `runtime-avatar.js` | `appendOrbit()` condition + `appendLongFieldStripes()` | +| Runtime change markers | `runtime-avatar.js` | `appendRuntimeChangeMarker()`, `resolveRuntimeChangeMarkers()` | + +`computeRingRecords()` uses `sourceOrderRatio`, not line length, for the base radius. `record.isLong` may still exist as record metadata, but it no longer controls the stripe visual. Stripes are appended only when `String(record.value || "")` matches `/[!?]/`. The old stripe geometry itself is preserved: seeded count, height, arc span, color, width, and opacity. + +Runtime hover/citation/reference glow variables are derived from the orbit's current `ringColor`, so a highlighted orbit keeps its own semantic color instead of flattening every highlight to cyan. Idle-opacity CSS targets only direct structural circles/lines; nested filled change markers are not accidentally dimmed with the base orbit. + +### Runtime Ring Speed + +The runtime orbit speed is based on snapshot diff: + +```js +const baseSpeed = 11 + random() * 36; +const effectiveSpeed = baseSpeed * (diffPercent / 100); +const duration = effectiveSpeed > 0.05 ? 360 / effectiveSpeed : 9999; +``` + +If the runtime memory barely changed, the rings nearly stop. If the diff is high, they move faster. + +To make runtime rings calmer: + +```js +const baseSpeed = 6 + random() * 18; +``` + +To make them more energetic: + +```js +const baseSpeed = 18 + random() * 52; +``` + +### Runtime Change Markers + +Runtime circles are no longer decorative and are no longer triggered by words such as `pending`. + +They show the last real runtime memory transition: + +| Marker | Meaning | +|---|---| +| Filled circle | A runtime line was newly added | +| Hollow circle | An existing runtime line changed | +| Marker size | Larger `key_change_ratio` / `value_change_ratio` | +| Marker angle | Stable hash of the runtime line identity | + +If a later snapshot has no real line changes, the previous change markers remain visible. The avatar searches backward through runtime snapshot history until it finds the latest real transition. This keeps the last meaningful transition visible instead of making the markers disappear on a no-op redraw. + +A removal-only transition clears the old markers: the removed line is represented by its orbit disappearing, so no stale circle is carried forward. + +Random orbit circles and pending-keyword circles are intentionally not rendered. + +## Runtime Colors + +Runtime colors come from a weighted palette. The avatar looks at text in the current runtime snapshot and blends colors if specific words appear. + +The default palettes live near the top of: + +`ui/static/js/runtime/runtime-avatar.js` + +| Palette | What it does | +|---|---| +| `KEYWORD_PALETTE` | Softly pushes rings toward thematic colors | +| `AGGRESSIVE_PALETTE` | Strong alert-like coloring for high-priority words | + +Current keyword palette: + +| Words | Color | +|---|---| +| `jin`, `runtime` | `#22d9b5` | +| `user` | `#9276d8` | +| `memory` | `#e1a449` | + +Current aggressive palette: + +| Words | Color | +|---|---| +| `angry`, `aggressive` | `#ff0000` | + +To add a soft visual theme: + +```js +[["project", "repo", "code"], "#65c99a"] +``` + +To add a warning theme: + +```js +[["error", "failure", "blocked"], "#ff4b4b"] +``` + +## Memory Signal Rings + +The memory signal rings are the outer dash/dot rings. They are not runtime memory lines. They represent separate memory systems around the current runtime state. The persistent-file perimeter sits one step farther out and uses dots instead of memory dashes. + +Memory dashes are configured in: + +```js +MEMORY_RING_LAYOUT +``` + +The file perimeter is configured separately in: + +```js +FILE_RING_LAYOUT +``` + +| Ring | Radius | Stroke / dot size | Meaning | +|---|---:|---:|---| +| Delayed | `168` | `3.10` | Delayed memory reports | +| L-T | `178` base, `+4` per extra 100 facts | `1.05` | Long-term facts | +| Active | dynamic midpoint between outermost L-T and Files | `2.175` | Active memory records | +| Files | `198` | dot radius `2.7` | Persistent files | + +The memory-ring render order is `delayed`, then `lt`, then `active`; the file ring is inserted after those and before the center. L-T intentionally sits between delayed reports and active memory. + +Each delayed/active item becomes one dash record. L-T always keeps one avatar record per fact, but archived L-T facts settle into dots instead of disappearing from the radar. The file ring uses one stable dot per persistent file. + +### Memory Ring Layout Controls + +| Field | Meaning | +|---|---| +| `radius` | How far from center the ring sits | +| `strokeWidth` | Thickness of a memory dash | +| `minArcDegrees` | Smallest dash length | +| `maxArcDegrees` | Largest dash length | +| `arcRatio` | How much of each item slot is filled | +| `arcTrimPixels` | Optional pixel trim before arc degrees are finalized; currently used by L-T | +| `startAngle` | Where the first dash/dot slot starts | +| `FILE_RING_LAYOUT.dotRadius` | Persistent-file dot size | + +Use these fields when you want to move a ring inward/outward or change how dense its records feel. Keep enough separation between radii for hover/link glows to remain visually distinct. + +## L-T Facts Ring + +The L-T ring shows all stored long-term facts. A directly exposed fact renders as a blue dash. A report-covered ordinary fact keeps the same avatar identity but renders as a dim dot. + +There are two base visual states: + +| L-T state | Meaning | Avatar | +|---|---|---| +| Visible / anchor fact | Fact stays directly available in long-term context | normal blue dash | +| Archived ordinary fact | Fact is listed by a delayed report as ordinary report content | dim blue dot; dash arc fades away | + +L-T uses one lane per 100 facts. The first lane sits at radius `178`; every additional hundred adds a new outer lane at `+4px`. Increasing the base radius from `168` to `178` gives every lane more circumference, so dense fact dashes have more real space instead of only being visually scaled. + +Current opacity: + +```js +opacity: record.archived ? 0.26 : 0.52 +``` + +Archived L-T records also pass: + +```js +dot: record.archived +``` + +File: + +`ui/static/js/runtime/runtime-avatar.js` + +Place: L-T branch inside `appendMemorySignalRing()`. + +### L-T Archived Meaning + +Archived does **not** mean deleted. It means the fact has been absorbed into delayed-memory report content and should not occupy a normal direct L-T line in context or the long-term panel. + +Current classification is intentionally simple and global: + +1. collect archive candidates from every report's `lt_facts_ids`; +2. collect every report's `anchor_lt_facts_ids`; +3. remove all anchor ids from the archived set. + +So the important direct-id rule is: + +**Anchor ids are removed globally from the archived-id set. Loaded/pinned does not remove an ordinary `lt_facts_ids` id from that set.** + +`factMatchesArchivedIds()` then checks both `fact.id` and `source_fact_ids`. That matters for merged/derived L-T records: even when the record's own id is anchored, an archived source id can still make the combined record classify as archived. + +A report being loaded or pinned can make its linked archived L-T dot glow through `is-delayed-memory-linked-hit`, but load state by itself never changes archive classification. + +This distinction prevents a report load from rewriting the structural meaning of L-T. Load/pin is context emphasis; `anchor_lt_facts_ids` is the structural exception that keeps an L-T fact exposed. + +### Delayed Memory Highlight Contract + +Delayed memory uses **one base blue hue and exactly two highlight tiers**. There is no third persistent DM highlight level. + +1. DM id cited in JIN output -> Tier 1 (soft). +2. Pinned DM, not explicitly loaded -> Tier 2 (strong). +3. Pinned + loaded DM -> Tier 2. +4. Explicitly loaded DM -> Tier 2. +5. Pinned DM1 cross-links DM2 -> DM1 Tier 2, DM2 Tier 1. The cross-link alone must not move DM2 upward in the delayed-memory panel. +6. Loaded DM1 cross-links DM2 -> DM1 Tier 2, DM2 Tier 1. +7. Any directly pinned/loaded DM highlights all of its own linked L-T facts at Tier 1; those L-T facts move upward in the long-term panel. +8. A secondary cross-linked DM does **not** highlight or promote its own L-T facts unless that DM independently becomes pinned or loaded. + +Transient hover/modal focus reuses Tier 1; it never introduces another visual intensity. Direct Tier 2 state always wins if both classes are present. + +### Cross-Report Anchor Signal + +A loaded/pinned report can contain an ordinary fact that is archived behind it while another report uses the same fact in `anchor_lt_facts_ids`. In that case the **other delayed report** receives the softer class: + +```text +is-delayed-memory-secondary-linked +``` + +That half-accent says: "this loaded report contains a hidden fact whose exposed anchor lives in another report." The delayed-memory panel mirrors this relation, and the report modal can surface the other report under `anchored_to` for the fact. + +### L-T Visual Edit Guide + +| Desired change | File | Edit | +|---|---|---| +| Make archived dots dimmer/brighter | `runtime-avatar.js` | change archived opacity `0.26` | +| Make visible L-T facts brighter | `runtime-avatar.js` | change `0.52` | +| Change L-T color | `runtime-avatar.js` | `LT_MEMORY_RING_COLOR` | +| Move L-T ring | `runtime-avatar.js` | `MEMORY_RING_LAYOUT.lt.radius` | +| Make L-T dashes longer | `runtime-avatar.js` | `MEMORY_RING_LAYOUT.lt.arcRatio` or `maxArcDegrees` | +| Change archived dot transition | `runtime-avatar.css` | `.jin-avatar-memory-dash.is-memory-dot`, `jin-avatar-memory-absorb-dot` | +| Change archive semantics | `runtime-lt-memory.js` | `getArchivedFactIdSet()` | +| Hide archived facts from avatar entirely | `runtime-avatar.js` | use visible facts instead of `getFactsWithArchiveState()` in `getLTMemoryAvatarRecords()` | + +The archived/visible classification itself is in: + +`ui/static/js/runtime/runtime-lt-memory.js` + +Important functions: + +| Function | Role | +|---|---| +| `getArchivedFactIdSet()` | Collects report-covered fact ids, then removes every globally anchored fact id | +| `factMatchesArchivedIds()` | Checks direct id and `source_fact_ids` | +| `getVisibleFacts()` | Returns only facts visible in the long-term panel | +| `getFactsWithArchiveState()` | Returns all facts with `archived` flag for avatar | + +## Delayed Reports Ring + +The delayed ring shows delayed memory reports. Each dash is one report. + +`getDelayedMemoryAvatarRecords()` treats a report as loaded when it is either pinned or present in the runtime's loaded delayed-memory id set.

Those ids feed the persistent file ring: a loaded report gives each non-pinned attached file a softer indirect-context accent, while focusing/hovering that report can give the linked file dot the stronger relational glow. + +| Desired change | Edit | +|---|---| +| Make normal reports more visible | raise normal `0.36` | +| Make loaded/pinned reports less intense | lower active `0.82` and/or edit dedicated delayed CSS | +| Make active report color less white | change `PINNED_DELAYED_MEMORY_RING_COLOR` | +| Change secondary-link intensity | edit `.is-delayed-memory-secondary-linked` | +| Move delayed ring | change `MEMORY_RING_LAYOUT.delayed.radius` | +| Make report dashes thicker | change `MEMORY_RING_LAYOUT.delayed.strokeWidth` | + +## Active Memory Ring + +The active ring shows active memory records. It is the outermost **memory-dash** ring and is intentionally bright; the file-dot perimeter sits beyond it. ACTIVE no longer owns a fixed radius. Its radius is recomputed from the current L-T lane count so it stays exactly halfway between the outermost L-T lane and the Files perimeter. + +Current behavior: + +| Visual rule | Value | +|---|---| +| Color | `ACTIVE_MEMORY_RING_COLOR` | +| Opacity | `0.76` | +| Stroke width | `2.175` (`4.35 / 2`) | +| Radius | `(outermost L-T radius + FILE_RING_LAYOUT.radius) / 2` | + +For example, with 153 L-T facts the L-T lanes are `178` and `182`, Files is `198`, so ACTIVE sits at radius `190`.

It is sourced from `window.JinFiles.getFiles()` and uses one dot per valid persistent file. + +Configuration: + +```js +FILE_RING_LAYOUT = { + radius: 198, + dotRadius: 2.7, + baseColor: "#7ab8d8", + glowColor: "#7ab8d8", + startAngle: -12, +} +``` + +The ring duration is seeded from the file-id set and falls in roughly `92..176s`. File records are sorted by id before assigning slots, so pinning/unpinning or delayed-context changes alter only appearance, never the dot's angular position. + +### File Dot States + +| State | Base appearance | Class / source | +|---|---|---| +| Stored, inactive | blue dot, opacity `0.36` | normal file record | +| Directly pinned/attached | bright white dot, opacity `0.96` | `is-memory-pinned`, `is-context-loaded` | +| Indirectly in context through loaded delayed report | half-accent, not white | `is-delayed-memory-context-linked` | +| Hovered in file UI | same half-accent as indirect context link | `is-memory-hover-hit` | +| Referenced by JIN / relation-focused | stronger cyan relation glow | `is-memory-reference-hit` / `is-delayed-memory-linked-hit` | + +A crucial distinction in `getPersistentFileAvatarRecords()`: + +- `contextLoaded` means the file itself is pinned; +- `contextLinked` means the file is **not pinned**, but at least one loaded delayed report lists its id in `attachments_ids`. + +Indirect context deliberately stays weaker than direct attachment. A pinned file keeps the stronger white state even while hovered or indirectly linked. + +### File Identity And Matching + +File hover identity is: + +```text +file: +``` + +Reference aliases include the six-character file id, original name, stored name, `/assets/files/...` context path, URL when available, and the stored name with the generated id prefix stripped. The SVG node also carries the linked delayed-report ids so `applyDelayedMemoryFileLinkGlow()` can light attachment dots when a delayed report is focused. + +File hover sources include the `[ files ]` memory panel, delayed-report attachment chips/picker options, and the fixed attached-files plaque. Pin/name/attachment hover can therefore target the same dot without duplicating identity logic. + +### File Ring Sync + +`syncFilesState()` compares the current file-id set with the rendered file ring: + +- same ids: update classes/data/colors in place and keep the current orbit animation; +- changed ids: rebuild the file ring; +- `jin:files-store-changed`: trigger sync; +- delayed-memory sync also triggers file sync because `attachments_ids` may change indirect context state. + +## Center Core + +The center is a visual anchor. It is drawn after all signal layers and sits on top. + +It is made of: + +- three thin circles; +- a soft radial glow; +- a soft inner circle; +- a core; +- a bright point. + +File: + +`ui/static/js/runtime/runtime-avatar.js` + +Main places: + +| Visual part | Edit | +|---|---| +| Center circles | `appendCenter()` | +| Core radius/opacity | `appendCenter()` | +| Default color | `DEFAULT_CENTER_COLOR` | +| Color transition speed | `CENTER_COLOR_STEP_MS` | +| Scene tint strength | `JIN_SCENE_COLOR_INTENSITY` | + +`setCenterColor()` also updates page-level CSS variables: + +| Variable | Meaning | +|---|---| +| `--jin-color` | Current JIN accent | +| `--scene-base-color` | Scene background tint | +| `--scene-jin-tint-alpha` | Scene tint opacity | + +Lower `JIN_SCENE_COLOR_INTENSITY` if the center color affects the page too much. + +## Ambient Shell, Depth, And Entry Softness + +The avatar shell now has two CSS-only depth layers outside the SVG: + +- `.jin-runtime-avatar-shell::before` โ€” a soft radial aura colored from `--jin-color`, breathing on a `9s` cycle; +- `.jin-runtime-avatar-shell::after` โ€” a dark radial/vignette depth layer that makes the radar feel embedded rather than flat. + +These layers are deliberately ambient. They do not represent memory records and they do not become stronger just because the memory panel is collapsed. + +Freshly redrawn runtime orbit entries use `jin-avatar-orbit-enter` for about `0.92s`, moving through a soft scale-in (`0.82` -> near full size -> slight `1.012` overshoot -> settled). This restores entry softness without changing the seeded orbit geometry. + +Reduced-motion rules disable the breathing/rotation/entry animations where appropriate. + +## Glow States + +Glow is mostly CSS.

+

Live Avatar visualizes JIN's runtime state in real time.

+

Inner orbits react to live FRAME/runtime-memory changes, while outer signal rings track Delayed Memory, L-T facts, Active Memory, and persistent files.

+

The non-rotating scaffold rings and breathing rays also mirror context pressure: they use the same green-to-warm progress color as the context meter, while ray peak opacity rises from roughly 0.10 toward 0.70 as the window fills. Rays fade fully out and back over a 30-second cycle.

+

The avatar is interactive: reasoning references light up matching runtime signals, memory-row hover zooms/highlights the corresponding signal, and larger L-T stores fan out across additional outer rings. The center toggle fades all scaffold/runtime/memory/file rings, then removes those hidden layers from painting/animation after the fade; the central light remains.

+

During reasoning, the avatar shifts into a dedicated motion state. Runtime actions can change its color, reaction, size, position, and speed, giving the model a small visual language beyond text.

-### Core Features +## Memory Architecture -- Visible runtime memory: JIN keeps a compact sense of what this session is about, what changed, and what still feels unresolved. -- Inspectable memory timeline: step through snapshots and see which facts or patterns were added instead of guessing what the assistant remembered. -- Think citation highlighting: rule fragments, runtime memory, and restored session context are softly highlighted after a thinking block completes, then reappear on hover. -- Session save and restore: natural closing phrases trigger a compact L3 memory digest, stored locally and replayed on reconnect. -- Active-memory contracts: reminders, ask-later conditions, and recall games live outside normal L1 summarization until JIN resolves them. -- Delayed memory reports: explicit requests to save a summary, digest, recap, or session summary for later become structured reports stored in browser `localStorage`, shown in the delayed-memory view, and kept separate from pending reminders or L1 facts. -- Facts memory: eligible L1 fields are mirrored into a per-session browser store, can be inspected or removed from the logger, and can be reassigned to an empty current session without duplicating the source bucket. -- Contract-driven runtime actions: markers, payload rules, blockers, confirmation guards, follow-up behavior, and display names are defined per action under `contracts/`. -- Guarded action lifecycle: pending actions are deduplicated, tracked through completion, failure, interruption, or abort, and finalized consistently when generation stops or the WebSocket disconnects. -- Pattern and loop detection: repeated exchanges can change strategy instead of producing the same polite answer again. -- Context pressure telemetry: model status, token usage, context pressure, runtime memory, and live logs stay visible in the right sidebar. -- Local OpenAI-compatible routing: use separate brain, service, and translator runtimes, or collapse to one service model for a simpler setup. +The memory panel has five views โ€” **FRAME**, **ACTIVE**, **DELAYED**, **L-T**, and **FILES** โ€” plus a **LOGS** archive view that projects saved sessions. -### Workspace Features +![Memory panel](ui/static/images/memory_panel.jpg) -- Streaming chat: answers appear as they are written, with thinking visually separated from the final reply. -- Stop generation control: the input turns into a stop control while JIN is working, so a drifting answer can be interrupted immediately. -- Built-in web-search action: the model can ask the runtime to search the web, then answer from returned evidence without rendering raw tool syntax. -- Asset workflows: reusable skills, wildcard lists, prompt templates, prompt batches, and generated outputs live under `assets/`, with runtime actions for listing, previewing, sampling, expanding templates, generating prompt batches, and checking duplicates. -- Live JIN color action: ordered `JIN_COLOR` markers update the avatar center, scene tint, and action bubble without forcing a follow-up turn. -- File attachments: drag, drop, paste, or pick images and text files; image chips support hover previews and modal previews, while text chips open their full content in the standard modal. -- Multilingual input path: Cyrillic input can be translated internally when translation is enabled, while the visible conversation remains natural. -- Keyboard-first writing flow: Enter sends, Ctrl/Shift+Enter inserts a newline. -- Deploy-friendly configuration: use a local `config.py` while experimenting, then switch to environment variables when running elsewhere. +### FRAME -## Architecture +**FRAME** is the live runtime-memory snapshot. It keeps the current topic, request/task state, decisions, feedback, and unresolved points needed by upcoming turns. Accepted updates are versioned as snapshots so the UI can step through diffs and inspect what changed. The latest FRAME value can also be edited directly from its memory tooltip; historical frames remain read-only. FRAME values follow the detected language of the current user message while structural keys remain English `snake_case`. -![schema](ui/static/images/schema.jpg) +### Active Memory -## Runtime Flow +**Active Memory** keeps unfinished intentions and pending commitments separate from the general conversation state. Conditions and unresolved contracts remain active across turns until they are fulfilled, cancelled, paused, or explicitly resolved. Relevant active records are projected back into Brain context without changing their canonical storage order. Conditions can be edited directly from the inspector while IDs, keys, custom fields, and status metadata remain structurally owned by the runtime. -The WebSocket layer creates a `RuntimeContext` per connection. Each user message is handled by `AgentRuntime`: +### Delayed Memory -- When translation is enabled, Cyrillic input can route through `planner -> translator -> brain -> validator`. -- The default input path is `planner -> brain -> validator`. +**Delayed Memory** stores larger structured context that should be available without living in every prompt. Reports can link L-T facts and persistent files, can be loaded/unloaded by runtime actions, pinned from the UI, or surfaced from matching user-text tags. Panel rows expose a compact hover preview with summary, tags, IDs, linked facts, creation time, and a bounded body preview; unpinning is also represented in the shared memory logger flow. -The translator node logs translator output for observability but does not render it as a chat message. The brain node streams the visible assistant response from the configured brain runtime. +### Long-Term Facts -The brain can emit runtime action markers. Per-action contracts under `contracts/` define the marker shape, trigger words, blockers, follow-up behavior, and display metadata. The runtime consumes valid markers as control events, executes them, injects trusted results into the next brain prompt when needed, and prevents raw control syntax from being rendered as chat text. +**L-T** is the UI view of durable facts: stable user/project facts, preferences, constraints, decisions, and environment details that should survive sessions. An internal candidate buffer feeds idle extraction and merge. Facts absorbed into Delayed reports stay hidden from the default active view but can be revealed with the count toggle; report-linked fact IDs open the owning report. Explicit fact values are editable, and fact mentions refresh recall so recently used facts stay fully expanded in Brain context while older facts fall back to compact sentence previews. -Current action families include web search, session save, active and delayed memory, skill and asset workflows, idle follow-up ticks, JIN color changes, and tool-result cleanup. Actions can share one turn while preserving marker order and distinct payload identity. +### Files -Actions that require explicit user intent can pause on a browser confirmation guard. Their UI lifecycle is tracked as pending, completed, failed, interrupted, or aborted; cancellation, stream interruption, timeout, and disconnect paths clear the same pending state instead of leaving a stuck action bubble. +**FILES** exposes the persistent uploaded-file library. Stored files keep stable IDs and can be attached/detached across turns or linked from Delayed Memory. Files attached to the next message also appear as compact composer chips: click to preview, hold to detach from context without deleting the stored file. -Active-memory records are stored separately from normal L1 memory, synced through the browser, injected as a high-priority `` block, and resolved by ID when their condition is met. +### Logs -After the visible response ends, the service runtime updates `context.runtime_memory` in the background. This request does not block the user-facing answer. The next brain prompt receives the current memory as trusted runtime context, and the right sidebar shows the same memory as plain text. +**LOGS** is the disk-backed archive browser for restorable sessions. Session titles come from the protected `session_title` field inside FRAME and update in the list when a newly committed FRAME changes the title; older archives without a title fall back to their session ID. Hovering a row loads a bounded preview of the newest USER/JIN turns, while a normal click opens that archived session through the existing restore flow in a new tab. Holding a row for 1.5 seconds uses the shared fade/delete interaction to remove that saved session from disk; an empty date directory is removed only when nothing else remains inside it. Anonymous and greeting-only/technical sessions are hidden from the archive. -Accepted L1 snapshots also update a session-scoped Facts Memory index in browser storage. This keeps durable fields inspectable without turning the live L1 snapshot into a permanent cross-session profile. +## Core Capabilities -The memory layer can also surface compact pattern signals. When the session starts repeating the same kind of interaction, JIN can receive strategy hints such as low-signal repetition or stalled context and respond differently instead of treating each message as a fresh start. +* **Inspectable Memory:** Keeps FRAME/live state, long-term facts, delayed reports, active commitments, persistent files, and the LOGS session archive as distinct systems. +* **Session Continuity:** Supports in-process soft WebSocket resume plus disk-owned reload/new-tab/bootstrap continuity and explicit archived-session restore from persisted logs. +* **Persistent Files:** Stores uploaded text, images, PDFs, and other files under stable ids; the same stored files can be attached to or detached from context across turns. +* **Runtime Telemetry:** Shows model status, token usage, live context pressure, memory updates, action state, and runtime logs; at 50%+ previous-answer context usage the Brain also receives a live `` warning, with an explicit cleanup reminder when tool results are present. Empty concerns are omitted. The status modal can switch the configured LM Studio model for an available runtime role. +* **Reasoning highlighting:** Displays provider/model reasoning separately from the final answer when the backend exposes a reasoning stream. Maps direct references back to runtime rules, memory records, restored context, and linked runtime objects. -Each memory update is also stored as a per-session snapshot. The UI can step backward and forward through those snapshots, replaying lightweight diff highlights so the user can see which memory keys or values were added or changed during the conversation. +![Reasoning citation highlighting](ui/static/images/think-highlight.jpg) -Completed thinking blocks are also scanned for direct citations from trusted prompt context. Rule matches, indexed runtime-memory matches, and restored session-memory matches are highlighted with separate colors so the user can see which injected source shaped the reasoning without interrupting streaming. +### Runtime Actions -If generation is aborted, the runtime captures the partial answer and schedules an interrupted memory update. The memory summarizer is instructed to mark the turn as incomplete and not treat it as resolved. +JIN can request an action while answering. The runtime validates and executes it, then returns any required result to the model before the workflow continues. Concrete contracts carry their own readable schema; a failed action is returned as a human-readable tool result with the reason, supplied payload when relevant, and the correct schema, followed by an explicit continuation instruction so the Brain does not treat the failed mutation as completed. Runtime execution preserves the model's emitted source order: each action is prepared and run before the next one; contract `runtime_order` only affects how action instructions are listed to the model. -When the user signals the end of a session โ€” explicitly or through natural closing phrases โ€” the brain emits a `SAVE_SESSION` action. The runtime builds a compact L3 digest from the current snapshot history and sends it to the browser for local storage. On the next connection, the browser sends the digest back as part of the bootstrap payload and the runtime injects it as trusted session context before the first turn. +Current contract families include: -## Runtime Memory +* `SAVE_ACTIVE_MEMORY` for both create/update, plus paired multi-ID `DELETE_ACTIVE_MEMORY`; +* `SAVE_DELAYED_MEMORY` and paired multi-ID `LOAD_DELAYED_MEMORY`; loaded reports are removable tool results, while only user-pinned reports enter the dedicated loaded-memory block; +* `LIST_ALL_USER_SHARED_FILES`, plus skill-gated `ATTACH_FILE_CONTENT` and paired multi-ID `ATTACH_FILES_BY_ID` (internally `ATTACH_FILE_BY_ID` per file); +* `LOAD_SKILLS_CONTEXT` and `UNLOAD_SKILLS_CONTEXT` accept comma-separated skill lists; the internal actions remain singular; +* `POSTING_BOARD` after the `posting_board` skill is loaded; +* `CALL_MCP` after any skill containing a valid `...` declaration is loaded; +* `JIN_COLOR`, `JIN_REACTION`, `JIN_SIZE`, `JIN_POSITION`, and `JIN_SPEED`. +* `WEB_SEARCH`, `DEEP_WEB_SEARCH`, and local `CHAT_LOG_SEARCH` when their capability gates allow them; +* `CLEAN_TOOL_RESULTS`, `UPDATE_LT_FACTS`, and model-facing ` F1, F2 `; -Runtime memory is intentionally lightweight, but it is no longer passive storage only. It gives JIN short-term continuity and can now influence conversational behavior when repeated patterns appear. +Concrete schemas in `contracts/*.json` are authoritative. -- It lives in the active `RuntimeContext`, not in a database. -- It is updated by separate service-model requests after a turn finishes. -- It is split into factual L1 memory, higher-level L2 pattern memory, a long-horizon L3 session digest, and separate active-memory, delayed-memory, and facts-memory channels. -- L1 is written as compact, actionable bullet-like state rather than full transcript history. -- L2 tracks possible repeated interaction patterns and occurrence signals during the active session. -- L3 is a compressed session summary generated at explicit save points and stored in the browser. It survives page reloads and reconnects. -- Memory is injected into the brain prompt as trusted runtime context. -- It is mirrored in the right sidebar through `runtime_memory_update`, `runtime_session_memory_update`, and `active_memory_records_update` WebSocket events. -- Each L1/L2 update is captured as a session snapshot with an index, raw memory text, parsed key/value lines, and diff metadata. -- Runtime-owned `active_memory_records` track pending contracts with IDs, status, creation time, elapsed time, and elapsed JIN-message counters; they are displayed and persisted, but stripped before L1 summarization. -- Delayed reports remain separate from L1 and are listed, appended, or removed from the current context by report ID. -- Facts Memory mirrors eligible accepted L1 fields into `jin.factsMemory..v1`; transient user-message, idle, JIN-response, and active-memory lines are excluded. -- The UI can navigate previous snapshots, replay visual highlights for new or changed memory fields, and show full memory suffixes line-by-line on hover. -- Conversation activity and no-signal alerts can suppress overly soft default behavior when the exchange is clearly stuck. -- Truncated or obviously incomplete summarizer output is rejected so it does not overwrite the previous memory. +## Architecture -This gives JIN observable short-term memory and behavior adaptation without introducing a server-side database, vector storage, or retrieval infrastructure yet. +![JIN Core Engine architecture](ui/static/images/schema.jpg) +### Runtime Flow -## Memory Snapshot Examples +The WebSocket layer resolves a session-owned `RuntimeContext` for the browser client. A soft reconnect can reattach to the same live runtime/transport instead of creating a new foreground state container; explicit page departure retires it, while an unexplained disconnect has a 600-second reconnect grace. Every accepted user message is then handled by `AgentRuntime`. -JIN memory is stored as plain `key: value` lines so it can be shown in the UI, injected into prompts, diffed between turns, and compressed into a later session digest. The keys are semantic handles rather than a fixed database schema, but the current runtime expects stable line shapes for important facts, active contracts, and pattern evidence. +A normal turn follows this path: -### L1 memory snapshot (facts) +1. The user sends a message with optional persistent attachments. +2. `AgentRuntime` passes the request directly to the Brain. +3. The Brain streams reasoning and visible answer content through separate runtime channels. +4. Stream validation guards repetition and malformed generation while private runtime-action markers are extracted. +5. Runtime Actions execute in model-emitted source order, can mutate state or return trusted results, and actions that need another model step continue inside the same user sequence. +6. After the visible turn completes, the logical Service route performs background FRAME integration; if no dedicated Service endpoint is configured, this route reuses the Brain client. +7. A later user turn waits for any pending FRAME update, then receives current Active Memory, `` followed by up to five recent USER/JIN pairs, loaded Delayed Memory, L-T facts, files/skills, action history, context-usage/concern signals, and trusted tool results. -L1 is the live factual layer. It keeps the current state needed for the next answer: user request, active topic, latest user message, current task, response feedback, durable facts, and unresolved normal conversation state. It is not a transcript and it should not infer long-term personality traits. +The model path is intentionally direct: ```text -user_message: "thanks" -last_jin_response: Acknowledged the user and kept the current runtime state compact. -active_topic: Runtime memory testing. -current_task: Verify that JIN keeps continuity without rewriting the full transcript. -open_question: User may continue testing active-memory behavior next. +user -> brain ``` -A rendered runtime snapshot also carries metadata used by the right-side timeline panel: - -```json -{ - "session_id": "runtime-session-id", - "index": 5, - "raw_memory": "active_topic: Runtime memory testing.\ncurrent_task: Verify continuity.", - "lines": [ - { - "key": "active_topic", - "value": "Runtime memory testing.", - "key_status": "same", - "value_status": "changed", - "key_change_ratio": 0.0, - "value_change_ratio": 0.42 - } - ], - "patch": { - "active_topic": { - "status": "changed", - "value": "Runtime memory testing." - } - }, - "total_diff": 87.3 -} -``` +Planning decisions, runtime actions, and follow-up decisions all happen inside the Brain/runtime loop. -Memory lines may also have temporary trace strength such as `[ trace: 0.50 ]` or inject `user_idle: 9s` into the displayed context. Those are runtime metadata signals, not durable memory facts. +### Model Roles -### Active memory snapshot (runtime contracts) +JIN talks to models through an OpenAI-compatible API. -Active memory is now owned by runtime, not by the L1 summarizer. It is stored as `active_memory_records`, persisted in browser `localStorage` under `jin.activeMemory.v1`, refreshed with runtime timing metadata, and injected into the brain prompt as a separate high-priority block. +The runtime separates model work into roles: -```text -active_memory_1: Secret word: Sun; ask the user to guess it later without revealing it [ active_memory_id: a1b2c3 ] [ conditions: Secret word: Sun; ask the user to guess it later without revealing it ] [ status: pending ] [ creation_time: 2026-06-20T10:00:00 ] [ created_jin_message_number: 3 ] [ elapsed_time: 00:02:39 ] [ elapsed_jin_message_number: 2 ] -``` +* **Brain:** visible reasoning, responses, and runtime decisions; +* **Service:** background memory updates and supporting work. -```xml - - active_memory_1: Secret word: Sun; ask the user to guess it later without revealing it [ active_memory_id: a1b2c3 ] [ conditions: Secret word: Sun; ask the user to guess it later without revealing it ] [ status: pending ] - -``` +JIN is model-agnostic at the API boundary. **Brain is the only foreground response route.** Service is background-only. `SERVICE_API_BASE` is optional: when it is empty, the Service client aliases the Brain client, so one physical model can handle both logical roles without changing foreground routing. Set `SERVICE_API_BASE` only when a dedicated background Service node exists. -JIN creates these records with `SAVE_ACTIVE_MEMORY` and removes them with `RESOLVE_ACTIVE_MEMORY` using the actual `active_memory_id`. L1 receives normal runtime memory with active-memory lines stripped out, so pending reminders and recall contracts are not accidentally rewritten by summarization. +On Windows, the LM Studio launcher can fill unset/default Brain model settings from a loaded Gemma-family model and can separately initialize a dedicated Service endpoint when one is configured. Explicit provider URLs and model ids remain unchanged. -### L2 memory snapshot (patterns) +### Runtime Storage -L2 works above L1. It watches recent L1 patch windows for repeated interaction patterns, loops, and same-intent behavior. It should describe hypotheses with occurrence counters and scope, not turn them into permanent user traits. +Reload/bootstrap authority is disk-owned. Browser cognitive state is a page-local projection: the live `jin.liveRuntimeMemory.v2` record is cleared whenever the page module starts.

Loaded skill bodies are projected through the normal tool-results context, while `` remains the compact availability/loaded-state inventory. Python skills execute from `.py` files inside the selected skill directory with bounded execution and output limits. Persistent uploaded files are stored separately under `assets/files/` and keep stable ids across turns. -This matters because JIN depends on more than plain chat completion. The runtime expects the brain model to follow layered prompt context, keep JIN identity separate from the underlying model, emit internal runtime-action markers reliably, and expose reasoning in a separable form when thinking traces are enabled. +### MCP skills -Smaller or non-thinking models may still run, but they can behave differently: ignore current runtime variables, leak reasoning into the visible answer, miss active-memory actions, repeat generic replies, or confuse recent-turn context with the latest user request. During active development, reported behavior should be compared against the Gemma 4 E4B + enabled reasoning baseline before treating it as a JIN runtime bug. +JIN is an MCP client for tool servers. A skill can declare one MCP server in its `JIN_SKILL.md` with a machine-readable `...` JSON block. Loading that skill opens/discovers the server, appends the live `tools/list` catalog to the in-memory skill context, and enables the single generic `...` runtime action. Tool-specific names and argument schemas stay in the skill/server; adding another MCP integration does not require another Python runtime action. -## Windows One-Click Launcher +Supported transports are `stdio`, Streamable HTTP, and SSE (`http` / `streamable-http` normalize to Streamable HTTP). Stdio connections remain alive across automatic JIN follow-ups and are closed when the skill/runtime is unloaded; an optional positive `read_timeout_seconds` applies to all supported transports. MCP image results are stored in the normal JIN file store and injected as image attachments into the next Brain follow-up, so visual tools can return screenshots/renders without embedding base64 into ``. Generic MCP bubbles open the structured request/result trace, while `get_viewport_screenshot` reuses the normal attachment preview.

LM Studio downloads are intentionally left to the LM Studio UI. +For LM Studio, JIN also probes the provider-native `/api/v1/models` metadata endpoint and falls back to legacy `/api/v0/models` when needed, allowing the runtime to read the context length of the model that is actually loaded. -When the Local Server is reachable, the launcher reads and prints the returned model IDs, then checks local `config.py`. +### Using an Existing OpenAI-Compatible Brain -For `BRAIN_MODEL_UID`, `SERVICE_MODEL_UID`, and `TRANSLATOR_MODEL_UID`, the launcher only writes a Gemma model automatically when the current value is empty or still uses the template defaults: `brain-model`, `service-model`, or `translator-model`.

An explicit Brain URL makes the Windows launcher preserve that configuration and skip the embedded `llama.cpp`/model bootstrap. `BRAIN_MODEL_UID` may be left empty so the launcher can discover the endpoint's model catalog. -For provider base URLs, the launcher points empty/template values at the working LM Studio base URL it found, but keeps user-defined values unchanged. +A single model is enough by default: with `SERVICE_API_BASE` left empty, background Service work reuses Brain.

Allowed actions are `observe` and `analyze` only; nothing is posted or modified without explicit user approval. - -**Background LLM job queue.** A non-blocking `BackgroundLLMJob` model and in-memory worker that moves heavy service-model calls (L3 session saves, memory consolidation, future night-brain tasks) out of the interactive chat path. The worker runs as an `asyncio` task inside the existing `lifespan` hook, respects a concurrency semaphore, and logs through the existing `log_memory_event` channel. Disabled by default via `BACKGROUND_LLM_ENABLED = False`. A Stage 2 adds fair scheduling across job sources to prevent one session from starving other background work. - +GitHub Actions runs the same suite. Browser client tests stay separate because they require Playwright and an Edge browser channel; run them explicitly with `npm run browser_tests` in an environment that provides those dependencies. Model-dependent probes remain local unless CI is connected to a compatible runtime. diff --git a/agent/__init__.py b/agent/__init__.py index 5dec6d97..1036de26 100644 --- a/agent/__init__.py +++ b/agent/__init__.py @@ -1,9 +1,7 @@ -from .router import Router from .runtime import AgentRuntime from .state import AgentState __all__ = [ "AgentRuntime", "AgentState", -

Connection, queue, and turn ordering + +### 3.1 RuntimeContext + +`runtime/runtime_context.py::RuntimeContext` is the central live state object. It holds, among other things: + +- clients and active streams; +- current/previous reasoning and visible answer state; +- runtime action history, action guard confirmations, tool results and follow-up state; +- live FRAME memory and snapshots; +- Active Memory records; +- Delayed Memory reports and loaded IDs; +- Facts Memory records and L-T store; +- attached file IDs and sequence attachments; +- session/reconnect/archived-restore metadata; +- L-T/background tasks; +- prompt-only L-T focus diagnostics; +- avatar color/size/position/speed related state; +- message/turn/sequence counters. + +Do not create a parallel state container for a concept already owned here unless the lifetime is intentionally browser-only or filesystem-persistent. + +### 3.2 Pending request queue + +The websocket endpoint uses a normal `asyncio.Queue` to serialize queued requests in FIFO order. Foreground work still has explicit guards around background L-T processing. + +The queue worker now belongs to the live `RuntimeContext` session through `runtime_transport`, rather than to a physical WebSocket. `websocket/transport.py` buffers serialized output until browser acknowledgement; reconnect attaches a new sender/receiver and replays unacknowledged events in order. Brain, FRAME waits, and pending USER batches keep running while the page is frozen/disconnected. A live transport reconnect does not apply a stale browser runtime/store snapshot. Process restart uses the disk-owned bootstrap path described in section 9; browser cognitive state is not a fallback authority. This delivery buffer is in-process transport state, not a new browser checkpoint or durable memory system. + +Page departure (`pagehide`, excluding back/forward cache) retires its transport +through a same-origin, exact-epoch close beacon, with WebSocket code 4001 as a +fallback. An unexplained disconnect retains the runtime for 600 seconds; a soft +reconnect cancels that deadline. Retirement cancels the session/guard/background +tasks, closes provider streams, releases both the resume-store and cached L-T +owner references, and discards the replay buffer. Accepted queued USER moves +use the existing interrupted-turn path; retirement cannot start another Brain +turn or finish a cancelled stream as a completed turn. + +### 3.3 Foreground turn + +`websocket/messages.py::process_message()` currently performs the foreground lifecycle: + +1. classify ordinary turn vs action-guard retry vs archived-session resume tick; +2. resolve current attachments; +3. establish turn ID and sequence ID; +4. reset per-turn transient state; +5. on ordinary turns: apply browser idle/Active/pattern/avatar state and auto-load Delayed Memory by user-typed tags; +6. append the user turn to the local chat log; +7. build `AgentState` and execute `AgentRuntime`; +8. persist reasoning log and emit action/session telemetry; +9. append visible JIN output to chat log/recent-turn state; +10. schedule normal or interrupted FRAME memory integration. + +A later foreground turn can wait for a pending FRAME update through `wait_for_runtime_memory_update()` so the Brain does not race stale live memory. + +--- + +## 4. Agent and model boundary + +`agent/runtime.py::AgentRuntime` is intentionally thin. It logs the flow and invokes `BrainNode` directly. + +```text +user request -> AgentRuntime -> BrainNode +``` + +There is no active planner/router node in front of Brain. + +Physical model endpoints are resolved through the client/config layer. Logical roles remain: + +- **BRAIN** โ€” the only foreground reasoning/visible-answer/runtime-decision route; +- **SERVICE** โ€” background FRAME, L-T, research, document-skill, and supporting model work. + +`utils/brain_client_utils.py::get_brain_runtime_config()` always returns label `brain`, and `BrainNode` resolves `context.clients["brain"]`. There is no active foreground branch to Service. + +`clients/registry.py` always builds the Brain client first and initially aliases `clients["service"]` to that same object. Only an explicitly configured `SERVICE_API_BASE` replaces the alias with a dedicated Service client. Therefore a one-model setup is the default topology, but the logical Service role remains background-only. + +`config_loader.py::normalize_model_role_config()` accepts `USE_SERVICE_AS_BRAIN=True` only as a migration adapter for old local configs: it promotes the old Service endpoint/settings into canonical Brain settings, clears the dedicated Service URL, deletes the legacy attribute, and then normalizes Service fallbacks. The Windows launcher contains matching legacy detection only so startup can find/migrate those old configs safely. No live runtime path reads the flag. + +Historical archives can still contain `role=service` / `RUNTIME_MODE=SERVICE`, and the logger UI retains presentation code for old `[SERVICE]` model-output cards. Those are reader compatibility paths, not a current response mode. + +The runtime status modal is also the current model-switch surface. For an available role it reads the LM Studio catalog/load metadata, posts the selected model and remembered load configuration to `/api/runtime-model/switch`, then reconciles against `/api/status` before presenting the switch as settled. This changes the physical model backing a role; it does not create a new foreground routing mode. + +--- + +## 5. Brain context assembly + +`rules/brain_context_builder.py::build_brain_context()` is the authoritative prompt assembly path. + +The current high-level order differs slightly between an ordinary user turn and archived-restore priming. + +Ordinary turn: + +1. optional `` โ€” first live-settings block when non-empty; +2. optional ``; it is omitted when empty, and from 50% previous-answer context usage it includes the percentage and can ask Brain to clean redundant tool results; +3. trusted runtime XML / enabled actions; +4. optional project-review context; +5. `TOOLS_RESULTS` โ€” this is also where loaded skill bodies are projected; +6. session action history; +7. attached-files inventory, then Delayed Memory inventory; +8. always-present `` availability/loaded-state inventory; +9. runtime-context group: explicit feedback/retry, Active Memory, current `` snapshot, then ``, visible session counters, loaded Delayed Memory bodies, L-T facts, and any zero-diff alert; +10. previous reasoning evidence/loop block when applicable; +11. runtime-action instructions assembled from current contracts; +12. identity block; +13. turn/loop rules. + +Archived restore priming deliberately moves continuity to the absolute front: inherited `` first, then `` when available, then ``. `` follows that restore preamble, after which the normal concerns/runtime/tool/action scaffolding continues. Restore resource metadata replaces the ordinary attached-file/Delayed inventories, and the ordinary previous-reasoning slot is suppressed because reasoning evidence was already projected at the front. + +On ordinary turns, `` takes the newest five recent USER/JIN pairs. The bound is pair count only: selected message bodies are not character-cropped. CRLF/CR is normalized, physical newlines are serialized as literal `\n`, surrounding whitespace is stripped, and XML-sensitive characters are escaped without removing the remaining text. + +The ordinary initial Brain prompt also includes the previous successfully completed reasoning in ``. Up to 2000 characters are kept whole; above that threshold the projection keeps the first and last 25% and replaces the middle with `CUTTED N chars`. Action/recovery follow-ups project visible dialogue first, then carried reasoning evidence, then `` and the current failure/recovery/tool state, rather than duplicating the ordinary previous-reasoning slot. + +Prompt text is a transient projection. Canonical state remains in `RuntimeContext` and filesystem stores; browser cognitive data is only a page-local projection. + +--- + +## 6. Streaming and runtime actions + +### 6.1 RuntimeStream + +`runtime/stream.py::RuntimeStream` owns the Brain stream lifecycle and separates: + +- reasoning; +- visible answer content; +- private runtime-action markers. + +Recovery paths also live around the stream/Brain sequence: repetition protection, context/output-limit continuation, stop/cancel, and action follow-ups. + +Brain-client and outer RuntimeStream action dispatch share one message-local `StreamActionQueue`. Marker parsing and visible chunks continue while asynchronous action execution waits. Actions remain ordered; normal completion drains their results before message-end/checkpoint/follow-up. Stream cancellation closes the queue so pending actions cannot outlive the turn. + +### 6.2 Contract-driven action boundary + +Concrete action schemas live in `contracts/*.json`. `contracts/rules_assembler.py` loads them and maps runtime actions to feature flags. Each concrete contract exposes a `schema` string array separately from its `rules`; the assembler emits `Schema:` before action rules, and `get_runtime_action_schema()` is also the canonical source used to explain invalid payloads back to the model. + +Current action names in runtime order are: + +- `DEEP_WEB_SEARCH` +- `WEB_SEARCH` +- `CLEAN_TOOL_RESULTS` +- `JIN_COLOR` +- `JIN_REACTION` +- `JIN_SIZE` +- `JIN_POSITION` +- `JIN_SPEED` +- `UPDATE_LT_FACTS` +- `RECALL_FACT_CONTEXT` โ€” internal source-backed L-T recall; the model marker is ` F1, F2 `; see [RECALL_FACT_CONTEXT.md](RECALL_FACT_CONTEXT.md). +- `CHAT_LOG_SEARCH` โ€” literal local archive search; see [CHAT_LOG_SEARCH.md](CHAT_LOG_SEARCH.md). +- `LOAD_SKILL` โ€” internal runtime name; ` skill1, skill2 ` expands an ordered comma-separated list. +- `UNLOAD_SKILL` โ€” internal runtime name; ` skill1, skill2 ` expands an ordered comma-separated list. +- `ASSET_ACTION` +- `POSTING_BOARD` โ€” skill-gated native Get Posting Board I/O (`feed`, `inbox`, `read`, `search`, `post`, `reply`, `ack`, `delete`). +- `CALL_MCP` โ€” enabled only when at least one loaded skill has a valid MCP server declaration; one generic action routes exact discovered tool calls. +- `LIST_ALL_USER_SHARED_FILES` +- `ATTACH_FILE_CONTENT` +- `ATTACH_FILE_BY_ID` (model-facing paired list marker: `ATTACH_FILES_BY_ID`) +- `SAVE_DELAYED_MEMORY` +- `LOAD_DELAYED_MEMORY` +- `SAVE_ACTIVE_MEMORY` +- `DELETE_ACTIVE_MEMORY` + +`runtime_order` above is the deterministic order used to assemble/advertise enabled action contracts in the Brain prompt. It is **not** an execution stage or priority. Once calls are parsed, the dispatcher follows model source order. +The default `rules/brain_context_builder.py` feature map enables the listed capabilities. Search is an additional effective-capability gate: `WEB_SEARCH` and `DEEP_WEB_SEARCH` are removed from the model-facing action set unless `app_settings.settings.CAN_SEARCH` is true. `CAN_SEARCH` currently means provider `serper` plus a non-empty, non-placeholder key supplied through `SEARCH_SERPER_API_KEY` or `JIN_SEARCH_SERPER_API_KEY`; the runtime deliberately does not guess a provider-specific key shape and leaves credential validation to Serper. The Windows launcher loads repository-root `.env` values into its child JIN process, while direct `python app.py` starts require the variables to be exported by the calling shell. The search client enforces the same gate before making a request. `POSTING_BOARD` is separately gated by the loaded `posting_board` skill: the skill owns the per-action API contract and safety rules, while the native runtime action owns HTTP execution, tool-result projection, follow-ups, logging, and UI events. Its API token follows the same process-environment path through `GETPOSTINGBOARD_API_KEY` or `JIN_GETPOSTINGBOARD_API_KEY` and is deliberately omitted from request previews/tool results. + +There is **no current `SAVE_SESSION` contract** in this snapshot. + +### 6.3 Parsing compatibility + +`utils/actions/regexp_utils.py` accepts more than the advertised canonical syntax so old/provider-specific marker forms can still be recognized. This compatibility is parser-level and must not be confused with the preferred model contract. + +A tag immediately preceded by an opening quote, backtick, or bracket is a literal marker reference. It must remain visible without starting/executing an action. The stream filter retains a trailing opener across chunk boundaries; both browser visual-marker renderers respect the same prefix rule. Whitespace between the opener and tag does not qualify. + +For close-tag actions, the canonical form remains a paired block. For short actions, legacy inline/colon forms may be recognized when the parser explicitly supports them. + +There is one deliberately narrow response-prefix fallback for provider/model formatting slips: before any visible non-whitespace answer text has been emitted, a standalone line may omit angle brackets and use exact `ACTION_NAME: payload` syntax. In this snapshot the eligible set is exactly `ATTACH_FILE_CONTENT` plus the five JIN visual compatibility actions (`JIN_COLOR`, `JIN_REACTION`, `JIN_SIZE`, `JIN_POSITION`, `JIN_SPEED`). Paired/block actions such as `WEB_SEARCH`, `LOAD_SKILL`, `LOAD_DELAYED_MEMORY`, or `RECALL_FACT_CONTEXT` are not inferred from a bare internal action name. The first ordinary or malformed nonblank line disables this fallback for the rest of the answer; normal `<...>` action parsing continues everywhere as usual. Unterminated candidate lines are held until newline/flush so trailing prose cannot be swallowed, and removing an accepted line consumes its empty line as well. + +The non-stream extractor and `RuntimeActionStreamFilter` use the same `allow_bare_prefix_fallback` switch/default, so whole-response and chunked paths do not disagree about whether the leading bare form is executable. + +Important current compatibility boundaries: + +- `CLEAN_TOOL_RESULTS` is a strict paired block. Targeted cleanup uses ` T1, T2, T3 ` with comma-separated exact tool-result IDs; the entire list is validated before mutation. An empty `` block performs full cleanup, including legacy ID-less results. The former bare marker and `` form are not executable compatibility syntax. +- `JIN_COLOR` and `JIN_SIZE` advertise paired XML with their payload in the tag body. Legacy inline/colon/space forms remain parser compatibility only. The stream filter must remove only the marker and preserve ordinary answer text before and after it, even across chunk boundaries. +- `JIN_SIZE` normalization preserves positive decimal `px`, `vw`, `vh`, and `%` values instead of stripping their units. Unitless values become `px`. The browser resolves relative values at application time against its live viewport: `%` uses the matching width/height axis, while `vw` and `vh` always use viewport width and height respectively. The ordinary room-state checkpoint still stores the clamped rendered pixel geometry, so reload does not reinterpret an old relative command against a different window. +- `SAVE_ACTIVE_MEMORY` is the single create/update contract. Without root `id`, it creates from `conditions` plus optional custom root fields. With root `id`, it updates that existing record using the remaining root fields; `conditions` may always change and custom fields must already exist. Parenthesized plain prose is never promoted into schema. Old `UPDATE_ACTIVE_MEMORY` payload shapes are rejected; the current write parser accepts only the flat `SAVE_ACTIVE_MEMORY` JSON shape and exact `AM-xxxxxx` IDs. +- `LOAD_SKILLS_CONTEXT` and `UNLOAD_SKILLS_CONTEXT` are public list markers for the singular internal actions. The immediately previous singular `*_SKILL_CONTEXT` paired tags remain localized reader compatibility; the model contract advertises only the plural list forms. +- `JIN_REACTION` advertises paired XML with a single emoji. Its older colon form remains parser/display compatibility only. + +### 6.4 Guard and dispatcher + +`runtime/action_guard.py` can pause selected state-changing actions for explicit confirmation when behavior-contract trigger requirements are not satisfied. + +`utils/actions/dispatcher.py::apply_runtime_action_calls()` is the central action execution fan-out. Its core invariant is strict source order: `A.prepare -> A.run -> B.prepare -> B.run`. Malformed telemetry may split batches, but valid calls are never reordered. The current action registry has no execution `stage`; contract `runtime_order` remains prompt-assembly metadata only. + +Action-specific rules should stay in contracts. `rules/runtime.py` should remain limited to cross-action sequence behavior and recovery rules. + +Tool results are deliberately human-readable rather than raw JSON. On failure, `utils/context/runtime_action_result_text.py` renders the failed status/reason, relevant supplied payload, and `Correct action schema:` from the same contract. `rules/runtime.py::ACTION_FAILURE_FOLLOWUP_MESSAGE` then tells Brain not to treat the failed action as completed and to continue from `TOOLS_RESULTS`. The error renderer, contract schema, and follow-up instruction therefore form one recovery path rather than three independent descriptions. + +### 6.5 JIN visual action state + +`utils/actions/jin_visual_actions.py` executes each accepted color/size/position/speed marker independently in dispatcher order. The browser applies each completed marker immediately; there is no visual-sequence collector or client-side sequence buffer. + +JIN_COLOR has additional persistence semantics: + +- accepted color updates set `RuntimeContext.jin_color` before the completed session snapshot is built; +- only a true no-op against the last applied color in the same runtime-message scope is skipped, so ordered alternation remains valid and a later message may request the same color again; +- each applied color is appended to the raw JSONL log as a `runtime_action_request` with a stable event ID, turn ID, timestamp, normalized color, and structured `session_action.parts[].colors` payload; +- a log-write failure is reported but does not block the already-valid UI event. + +The raw event is the durable archive recovery path. It is not a second live state owner. + +### 6.6 Session-action telemetry is causal + +Session-action history is not only an end-of-turn summary. `runtime/stream.py` records and emits interruption/recovery entries at the moment the cause is detected so the logger changes before any automatic follow-up begins. This applies to reasoning/content validator loops and model context/output-limit recovery; `context_overflow` is treated as a context-limit finish reason. Provider/preflight overflow errors enter the same recovery path. Native `chat.end`/`stop` also enters it when actual provider input plus output tokens fill the loaded window. Limit entries retain a separate history row through compaction. + +That ordering is part of observability semantics. Moving the emission back to final compaction makes the logger describe the past only after JIN has already continued. + +--- + + +### 6.7 Malformed action recovery + +The stream parser also recognizes three non-executable forms for enabled action +names: tool-call wrappers with an object payload, paired tags with attribute +payloads, and short payload-bearing actions incorrectly emitted as paired tags +with a `{ key="value" }` body. The existing quote-prefix rule still protects +literal examples. Known unfinished envelopes remain private at stream flush. + +Each detection is dispatched as internal `MALFORMED_ACTION` telemetry, never as +the attempted mutation. It receives its own T-id, action bubble and preserved +Session Actions row. The existing runtime tool-result store persists the action +name and original extracted payload. Ordered `MALFORMED_ACTION_NOTIFICATION` +blocks lead the shared follow-up prompt and obtain the correct syntax exclusively +from the target contract's `schema` array. Valid results in the same response +remain in that same follow-up. + +Malformed recovery gets at most one dedicated repair follow-up outside the ordinary workflow budget. If the repair response is malformed again, the sequence stops instead of opening an unbounded repair loop; Brain then receives one final non-executable response tick with runtime actions disabled. User Stop and transport/provider interruption retain their normal behavior. + +--- + +### 6.8 MCP loaded-skill bridge + +MCP is an extension of the existing skill/action path, not a parallel agent framework. A canonical skill declares one server in `...` inside `JIN_SKILL.md`. The parser also recognizes legacy `` as compatibility input, but new documentation and skills use ``. Supported transports are `stdio`, `streamable_http` (including `http` / `streamable-http` aliases), and legacy `sse`; an optional positive `read_timeout_seconds` is passed to the MCP client. Stdio declarations may also provide `cwd`, static scalar `env`, and `env_from_host` mappings/lists so secret host values do not have to appear in model-visible skill text. + +Loading a valid MCP skill establishes/discovers the server with `tools/list` and appends one ephemeral `` block to the in-memory loaded skill. That block carries server identity/instructions plus live tool names, descriptions, and input schemas; the source `JIN_SKILL.md` is not rewritten. `CALL_MCP` becomes model-visible only while at least one valid MCP skill is loaded. Calls must name an exact loaded skill and exact discovered tool, are deliberately excluded from result-reuse caching, and use one persistent asyncio-owned MCP connection per loaded skill so server/session state survives automatic Brain follow-ups. Unload/runtime retirement closes that connection; a changed MCP config creates a fresh one. + +MCP image blocks are decoded with a 20 MiB per-image limit, stored as normal pinned JIN files, stripped of raw base64 in the tool result, and synchronized into the current-turn/sequence attachments so the next Brain follow-up can inspect them. The UI keeps Session Actions compact (`CALL_MCP: skill / tool`), uses a structured MCP payload/result modal for generic calls, and reuses the attachment hover/click preview for `get_viewport_screenshot`. Static server identity/instructions stay in discovery context instead of being duplicated into every tool result. See [MCP_SKILLS.md](MCP_SKILLS.md). + +--- + +## 7. Memory architecture โ€” current model + +The old numbered four-layer architecture is not the current implementation. + +### 7.1 FRAME / live runtime memory + +FRAME is the compact live runtime state exposed in the memory panel and as `` in Brain context. It is integrated through the logical Service route after foreground turns, has snapshots/diffs, and has a distinct interrupted-turn update path. With no dedicated Service endpoint, that background route deliberately reuses the Brain client. The FRAME integration prompt detects the current user-message language for values while keeping structural keys as English `snake_case`; localization is a value-format rule, not a schema rename. + +FRAME includes the reserved `session_title` line. The existing FRAME summarizer emits it as part of every replacement snapshot, including the normal hidden-bootstrap lifecycle; Python restores the previous value only when a model response omits it. The field is excluded from L-T candidates and cannot be removed through FRAME row deletion. + +FRAME is not a durable long-term tier. Its implementation modules, state fields, events, pending journal, UI identifiers, and tests use FRAME naming consistently. + +### 7.2 L2 and L3 + +There are no `runtime/L2_memory.py`, `runtime/L3_memory.py`, `runtime/L2_memory_utils.py`, or `runtime/L3_memory_utils.py` modules in the verified snapshot. + +Remaining L2/L3 names occur in stale tests, old docs, comments, UI compatibility text, and historical session fields. Those names are not evidence that the layers still exist architecturally. + +### 7.3 Facts Memory + +Facts Memory is a companion candidate index produced from FRAME snapshots on the server. Its durable source is `memory/facts/pending_facts.json` (or `pending_facts_anon.json` in anonymous mode); browser facts-memory buckets are only a projection of that file-backed profile. + +`facts_memory_store_sync` no longer makes an ordinary browser inventory authoritative. It has one narrow upgrade bridge that can import pre-file-store browser candidates once while the pending-facts file carries a legacy migration flag. Backend L-T code then normalizes these records and marks analyzed fields. This is an intake/candidate mechanism for L-T, not an independent durable product layer equivalent to old L2/L3. + +### 7.4 L-T long-term memory + +Active modules: + +- `runtime/LT_memory.py` +- `runtime/LT_memory_rules.py` +- `runtime/LT_memory_utils.py` +- `utils/long_term_facts_file_store.py` + +L-T owns durable facts. The current L-T path includes: + +- Facts Memory candidate ingestion; +- extraction phase; +- merge/rebase/validation phase; +- explicit-edit protection; +- links to Delayed Memory reports; +- archive/anchor classification; +- delete/restore reconciliation; +- server/browser store synchronization; +- persistent mention tracking (`mention_count`, `last_mentioned_at`) and historical-log backfill; +- recall decay: after 24 hours without a mention, Brain context uses sentence previews capped at 100 characters per sentence until JIN references the fact again. + +A valid `F` reference in JIN reasoning or visible output counts once per turn for that canonical fact, updates `last_mentioned_at`, increments `mention_count`, persists the store, and makes the next prompt eligible for the full fact value again. Historical mention backfill may repair older dates but never rewinds a newer live mention. + +In the current single-server-event-loop deployment, L-T commits are synchronous: +read/reconcile the latest file state, apply the change, then persist without an +intervening `await`. Backfill scans archives in a worker but performs this whole +commit on the event loop too. Offloading only the final snapshot write breaks +that ordering and can overwrite another page's committed edit/deletion. This +does not provide cross-process locking for multiple servers sharing one file. + +L-T work is scheduled from an explicit browser idle tick (`lt_memory_idle_tick`) and is guarded so it does not begin while foreground work is running or queued. Explicit `UPDATE_LT_FACTS` notes instead queue during Brain dispatch and wait for that turn's FRAME task to finish applying and publishing state before their Service request starts. The request-card event is not a completion boundary. Cancelling an explicit L-T waiter for a new USER preserves both its queued note and the running FRAME task. + +### 7.5 Delayed Memory + +Delayed Memory stores larger structured reports in `memory/delayed/*.json`, with file-store logic in `utils/delayed_memory_file_store.py`. + +Current save contract: + +```text + +{ + "title": "", + "summary": "", + "tags": [], + "body": "", + "anchor_lt_facts_ids": [], + "lt_facts_ids": [], + "attachments_ids": [] +} + +``` + +Important semantics: + +- report inventory and loaded report body are different prompt concepts; +- reports can link L-T facts and persistent files; +- `anchor_lt_facts_ids` must be a subset of `lt_facts_ids` under the current contract; +- loaded/pinned/referenced/inspected are different states; +- old key/value `SAVE_DELAYED_MEMORY_CONTENT` form is legacy only. + +### 7.6 Active Memory + +Active Memory is live unresolved structured state/commitments, stored independently from FRAME text. + +Current model-facing boundary: + +```json +{"conditions":"...","custom_field":"..."} +``` + +The same `SAVE_ACTIVE_MEMORY` block updates when `id` is present, for example: + +```json +{"id":"AM-abcdef","conditions":"updated...","custom_field":"new value"} +``` + +Creation custom fields are explicit structure only: JSON root fields beside `conditions` are accepted (up to the current three-custom-field cap), while non-JSON text is preserved as conditions and is not mined for `(field: value)` suffixes. Duplicate normalized JSON keys follow normal last-value-wins behavior before the cap is applied. + +Historical nested `fields`/`updates`, line-based update payloads, self-closing UPDATE attribute forms, old `active_memory_id` storage fields, and bare six-character Active Memory IDs are not accepted by the current write/storage path. Internally/browser-side, Active Memory is still represented in a string-record format with metadata suffixes; the identity suffix is `[ id: AM-xxxxxx ]`. + +Paused Active records are removed from the Brain prompt. Memory Attention may reorder the prompt projection by lexical/context relevance without changing canonical storage order. + +### 7.7 Persistent Files + +Persistent uploads are owned by `utils/attached_files_store.py` and `assets/files/` plus its index. Stable IDs are reused by: + +- prompt attachments; +- Delayed report links; +- file actions; +- UI memory/file projections; +- Live Avatar/link highlighting. + +The composer projects currently pinned files as compact attachment chips. A chip opens the existing file preview on click and uses the shared hold interaction to detach/unpin it from the outgoing context. Detach does not delete the underlying persistent asset, and attachment changes do not implicitly expand Console. + +### Project review through linked files + +` id1, id2 ` expands to ordered +internal `ATTACH_FILE_BY_ID` actions and attaches whole existing persistent files through +the ordinary pin/hydration path. Text uses the shared attachment context budget; +images use the existing multimodal Brain payload when image input is enabled. +It accepts only system IDs, never paths, stored filenames, or line ranges. + +` id1, id2 ` expands to ordered +loads whose report bodies are stored as individually identified tool results. +Model loading never writes ``; that durable context block +is reserved for reports the user explicitly pins. There is no model-facing +`UNLOAD_DELAYED_MEMORY` contract because `CLEAN_TOOL_RESULTS` removes model-loaded +reports from context. +Missing/deleted IDs fail without falling back to project reading. Its result +uses the existing bubble, Session Actions, tool-result and checkpoint paths. +`ATTACH_FILE_CONTENT` remains the source-path/range reader, with its old +persistent-ID handling retained for compatibility. + +`LINK FOLDER` beside `ATTACH FILE` accepts a local path (including a folder +copied into `assets/`) or a `file:///` URL. The user-facing endpoint validates +the directory and stores an ordinary `.jin-folder` descriptor in Files. Its +existing id, pin/unpin, preview, delete/restore, and session attachment paths +remain authoritative. Deleting the descriptor never deletes the project. +Remote repository URLs, project writes, execution, indexing, and ingestion +are outside this increment. + +An attached folder activates the prompt-only `PROJECT_REVIEW` projection. +Brain retains recent conversation, FRAME, ACTIVE, and exact accumulated +reasoning across follow-ups. DELAYED inventory/bodies are restricted to +user-pinned reports; L-T is restricted to their linked facts. Historical +memory tool results cannot reintroduce excluded bodies. Canonical memory is +not cleared. Detaching the folder returns to ordinary context assembly. + +`ASSET_ACTION` exposes `project_tree` and `project_search`. File loading uses +`ATTACH_FILE_CONTENT: file_id` or `ATTACH_FILE_CONTENT: relative/path#L1-L200`; +Relative paths +resolve against the single attached folder; multiple folders require +`folder_id/relative/path`. Known persistent IDs retain priority, and only a +known folder ID is treated as a prefix, not any six-character directory name. +The old +`project_read` subaction is only a compatibility adapter to the shared loader. +Paths remain confined to a user-attached folder. Reads are bounded exact +UTF-8 source ranges; actionable limits are reported without boilerplate. + +`runtime_tool_results` owns project read snapshots, using its existing +persistence/bootstrap path; no separate loaded-file registry is added. +`FILE_CONTENT` projects each loaded body once, below compact TOOL_RESULTS. +Persistent attachments use the same projection, not USER/flow text. Explicit +ranges may be read again; the newest result owns the visible FILE_CONTENT for +that range, while a bare project path advances to the next unread window. +CLEAN_TOOL_RESULTS clears project snapshots along with tool results. Removing +a folder from the user attachment set unloads its source bodies. The normal +persistent file store and source project remain unchanged. Browser/backend reload restores exact loaded ranges from the archived disk +checkpoint/tool-result events; unpinning a folder does not resurrect old source +bodies from browser state. + +The ordinary dispatcher, bubbles, session actions and Brain follow-up loop +remain in use. Independent file markers can share one response; Brain is +briefly instructed to save useful findings, clean stale tool results, and continue reading. +Brain may save a DELAYED report during review without a separate save request; +this is a scoped exception to the ordinary report trigger. ACTIVE and L-T +updates retain their existing handlers and persistence policies. + +### 7.8 Direct memory value editing + +`runtime/memory_edit.py` implements explicit inspector edits without sending a model action. The browser opens the existing hover/details card as a page-local editor on double-click. Only values are editable: + +- **FRAME:** only the latest frame; historical snapshots are read-only, and reserved Active/user-idle rows are rejected; +- **Active:** the record conditions/value; IDs, custom fields, pause status, creation metadata, and other suffixes are preserved; +- **L-T:** only the canonical fact value; ID/key/category/provenance and mention metadata are preserved. + +The request carries the expected value, so concurrent/stale edits fail instead of overwriting a newer value. Manual FRAME edits and row deletions are rejected while live FRAME/foreground integration is busy because that same state is being replaced. Active edits remain available during Brain/FRAME work: Active owns `active_memory_records`, and FRAME snapshots project the current Active store rather than owning it. L-T edits persist to disk before publication and are unavailable when persistent writes are restricted. Active and L-T acknowledgements surface `updated_at` immediately in the open editor. Draft text remains page-local until the checkmark is acknowledged; rollback restores the last acknowledged value. + +--- + +## 8. Memory Attention + +`runtime/memory_attention.py` is a small, deterministic prompt-projection module. It implements only: + +- lexical/current-context relevance ordering for Active Memory; +- temporary bubble tiers for Delayed Memory inventory matching; +- a narrow 1โ€“3 relevant-fact focus cone for L-T. + +Memory Attention is stateless. It does not call SERVICE, mutate or persist memory records, add prompt instructions, modify Brain temperature, drive avatar state, or maintain significance scores. Canonical storage/UI order remains independent from the prompt projection. + +--- + +## 9. Persistence and session continuity + +JIN deliberately splits persistence by owner/lifetime. + +| State | Current storage/owner | +| --- | --- | +| live runtime FRAME for soft reconnect | server `RuntimeContext`; page cache is a projection | +| continuation state | raw session JSONL checkpoints/actions + latest saved FRAME | +| Active Memory | `memory/active/.json`; anonymous uses `_anon.json`; ids use `AM-xxxxxx` | +| Facts Memory candidates / pending extraction | `memory/facts/pending_facts.json`; anonymous uses `pending_facts_anon.json` | +| Delayed Memory | `memory/delayed/*.json`; anonymous reports use the `_anon.json` suffix | +| L-T facts | `memory/facts/long_term_facts.json`; anonymous uses `long_term_facts_anon.json` | +| FRAME crash-recovery journal | normal rooms: `memory/frame/*.frame_pending.json`; disabled for anonymous rooms | +| persistent files | `assets/files/` + file index | +| visible chat / reasoning logs | `logs/` | +| live in-process orchestration | `RuntimeContext` | + +Chat-log paths are reserved without creating directories. Prepared context and inherited FRAME snapshots wait in the live context until a dialogue row, runtime action, or non-empty reasoning is actually written; a stopped blank bootstrap leaves no session directory. Interrupted reasoning is retained without manufacturing a completed JIN row. JSONL rows omit the redundant `dialog_path`; reasoning files retain their useful backlink. + +FRAME audit files live beside `reasoning/` in `frames/_frame_.txt`, sharing the session log prefix and visible FRAME number (including the reconnect offset). Creation, bootstrap projection, and in-place refresh use the same writer; a refresh replaces its own frame file, including an emptied frame, while older frames remain intact. These inspectable files also supply the latest FRAME during disk bootstrap; new files preserve the full snapshot metadata. + +### 9.1 Server-owned bootstrap and reconnect (D057, 2026-09-26) + +Normal connection sends an empty `session_bootstrap` request. The server selects the newest surviving real USER archive, ignoring every browser snapshot field, timestamp and owner ID. An explicit archive checkout sends only `archived_session_restore` and `source_session_id`; the server rereads that archive. Read errors are surfaced, never used as permission to import browser state. + +The existing archive builder combines USER/JIN rows and reasoning, structured action history, server `session_checkpoint` events and later cleanup/tool-result events. Latest `frames/_frame_.txt` wins over the earlier prompt's FRAME. New frame files embed the complete snapshot metadata beside the readable FRAME; legacy files retain their text fallback. Explicit empty FRAME and tool inventories stay empty. A single server `bootstrap_state` response feeds the existing UI projection, followed by the established FRAME/actions/chat-tail events and hidden continuation tick. + +`RuntimeContext` remains the live owner. Soft reconnect with a surviving transport sends no browser state. After server restart, the same page requests disk bootstrap again. `runtime_resume` snapshots are ignored. Active/Delayed/Facts/L-T remain disk-profile-owned; automatic legacy browser Facts imports are disabled. + +Normal cognitive caches use page RAM, with the existing ephemeral FRAME record cleared on every page load. The `jin.sessionCheckpoint.v2` and older durable cognitive records are retired and removed on startup, without migrating their contents. UI preferences remain in localStorage. An in-page checkpoint API remains for existing projection callers; it cannot become a reload source. + +### 9.2 Lifecycle, clear and disk persistence + +D049 remains unchanged: greeting-only tabs are not saved continuation sessions; a real USER send qualifies immediately, including interrupted USER-only/action-only turns. Latest-source selection and explicit archive restore retain their existing separate semantics. Dialogue/reasoning keep original timestamps and the five-USER-move bound. + +The transport archives the same server `session_snapshot` projection it emits, only after a session log exists. New tool results are recorded at the canonical tool-result writer; cleanup events preserve the exact remaining inventory and monotonic tool ID sequence. FRAME keeps its existing deferred writer. None of these writers can recreate a physically deleted materialized archive. + +Session CLEAR writes an atomic `logs/.continuation-cleared.json` barrier of USER row counts, without deleting archives. Later passive output, room updates or other tabs cannot lift the barrier. A newly logged USER row can. This avoids timestamp precision races and keeps explicit archive checkout available. + +### 9.3 Normal bootstrap chat tail + +After backend hydration, normal bootstrap emits at most the five newest `runtime_recent_turns` to the browser. Each item may carry USER text, JIN text, saved reasoning, and original timestamps. Attachment-context boilerplate is removed from the visible USER bubble. + +The client rebuilds the tail through the existing chat primitives. It keeps a real USER-only interrupted/action-only turn but does not manufacture an empty BR bubble. It then appends a divider labelled with the source session's last message time (`jin_created_at`, otherwise `user_created_at`, in the browser's local timezone; no dated divider if neither timestamp is available) and activates the live-turn viewport at that boundary, leaving the inherited five-turn history immediately above the initial screen. Explicit archived restore owns its own rendering path and suppresses this normal-bootstrap tail. + +### 9.4 Archived session restore + +Archived restore is a distinct path: + +1. HTTP endpoint `/api/sessions/{session_id}/restore` builds payload from logs via `utils/session_restore.py`. +2. Browser renders the bounded five-USER-move tail from the RESTORE endpoint and sends only the explicit archive selector; the WebSocket resolves it from disk again. Saved reasoning is attached to its owning JIN turn after archive-file metadata is removed; later visible JIN-only restore rows remain in order. +3. Backend sets `runtime_session_restore_priming` and stages historical resource IDs/metadata. +4. A hidden `archived_session_resume` Brain tick receives restore-specific context. +5. The hidden restore prompt projects the newest complete visible USER/JIN dialogue in ``, with compact relative ages derived from archived timestamps, then carries the previous reasoning evidence in `` when available, and only then emits the mandatory automatic-restore notification. There is no separate raw reasoning dump or replay of old action markers as executable intent. +6. Historical loaded Delayed IDs and attached files are staged until after the restore greeting; room/avatar state is already restored by the bootstrap path and is not replayed as runtime actions. +7. `BrainNode` consumes the staged restore envelope and replays only those delayed-memory/file resources through the normal runtime-action dispatcher. +8. The WebSocket tail performs defensive cleanup only; it must not apply the same resources a second time. + +At prompt-build time the restore instruction prepends the fresh runtime session ID and timezone-aware current time directly above `!!! USER DIDN'T SEND NEW MESSAGE! !!!`. Archived USER timestamps remain historical dialogue metadata and are never reused as the bootstrap time. + +The legacy restore-reasoning dump is retired. Saved reasoning remains available to archive/UI continuity and restore-derived metadata such as the latest reasoning/fact references, but it is not serialized into a separate bootstrap dump. Restored visible dialogue uses the normal five-pair limit and, like ordinary recent-message context, does not impose a per-message character cap. + +The RESTORE endpoint owns archived dialogue, reasoning, FRAME and presentation state for explicit URL checkout. Browser caches never override that bundle. Historical wrappers remain reader compatibility, and the inherited dialogue/reasoning is projected before the mandatory automatic-restore notification. + +`GET /api/sessions` is the compact read-only archive index used by the memory panel LOGS tab. It returns only session identity/date/creation time/title, excludes anonymous and non-USER technical sessions, and resolves titles from the same committed FRAME precedence used by restore. Legacy untitled rows display their session ID. + +LOGS materializes archive rows in the shared scroll-driven lazy batches. The full HTTP index is fetched once per page, then disk-backed `archived_session_update` events insert/update the active session row live; a focused `GET /api/sessions/{session_id}/summary` reconciliation repairs a missed event without reloading the archive. A row hover uses the common memory hover-card shell and fetches at most the five newest USER-owned turns from `GET /api/sessions/{session_id}/preview`; unanswered/action-only USER turns remain eligible, and leaving the row aborts the request and removes the preview DOM. + +A short row click opens `/?restore_session=` in a new tab. The shared 1500 ms hold/delete interaction calls `DELETE /api/sessions/{session_id}`. Deletion is restricted to indexed USER-owned, non-anonymous, non-symlinked archive directories; the date directory is removed only if it becomes empty. The live chat logger refuses to recreate a physically deleted materialized session, so a still-open runtime cannot resurrect a deleted LOGS row. + +`utils/session_restore.py` still understands historical `SAVE_SESSION` labels in archived logs. That is restore compatibility, not proof of a current `SAVE_SESSION` runtime action. + +### 9.5 Timestamp invariant + +Modern records/snapshots should retain original creation timestamps across serialize -> reload -> hydrate. `now()` is only a fallback for truly legacy records without a timestamp. Rendering/loading must not rewrite historical time. + +--- + +## 10. Anonymous room mode + +Anonymous mode is an explicit JIN room state, not browser-private/incognito detection. A long press on the avatar opens a fresh room URL carrying `anonymous_mode=1` and a generated `_anon` runtime/session id. + +Backend behavior: + +- runtime is marked anonymous and unrelated persistent side effects remain restricted; +- Active, Delayed, Facts Memory candidates, and L-T use the same file-backed profile machinery as normal mode but with `_anon.json` filenames; +- those anonymous memory files are shared by concurrently open anonymous rooms and are removed after the last anonymous room closes; +- the FRAME crash-recovery journal under `memory/frame` is disabled; +- `UPDATE_LT_FACTS` and `SAVE_DELAYED_MEMORY` mutate only the anonymous file-backed profile; +- Delayed sync supports restore, pin/unpin, and delete against the anonymous profile without touching normal files; +- a soft WebSocket reconnect preserves the room's reports and loaded bodies; +- persistent asset-write actions are restricted; +- chat and reasoning still log normally under `logs//_anon/`; +- normal restore/bootstrap and L-T log-freshness scans ignore `_anon` sessions. + +Browser behavior: + +- `sessionStorage` still carries tab-local room/bootstrap state, but it is not the source of truth for Active/L-T/Delayed/Facts Memory; +- server `memory_profile_snapshot` replaces browser memory projections from the `_anon.json` files; +- normal `localStorage` Active/L-T/Delayed/Facts Memory data is not allowed to seed the anonymous profile; +- a dedicated scene tint visually marks the room. + +--- + +## 11. Stop, interruption, and recovery + +`websocket/tasks.py::cancel_current_task()`: + +- marks the active turn interrupted; +- can distinguish discard vs interrupted-memory update; +- aborts active runtime actions; +- closes active model streams; +- cancels the task; +- can schedule the interrupted FRAME update. + +`process_message()` later routes interrupted turns through `schedule_interrupted_runtime_memory_update()` instead of pretending the turn completed normally. + +The Brain/stream layer also contains recovery for reasoning repetition and model/context output limits. Follow-up ticks preserve sequence identity rather than starting a new user request. They explicitly suppress the ordinary previous-reasoning projection and carry the relevant current-turn or loop-recovery reasoning through their dedicated builder. The corresponding session-action interruption entry is emitted before that recovery/follow-up starts, not deferred until the final answer. + +--- + +## 12. UI synchronization and Live Avatar + +The browser is a projection of runtime state, not an independent semantic authority. + +Important shared identities include: + +- Active Memory IDs; +- Delayed report IDs; +- L-T fact IDs; +- file IDs; +- runtime action IDs; +- turn/sequence IDs. + +The Live Avatar and memory panels consume the same identities but may show different **strength** depending on cause: + +- object actually loaded into context -> active/strong state; +- object merely referenced/cited by ID -> weak linked state; +- object only inspected in a modal -> no implied context load. + +Do not collapse these into a generic highlight state. + +The L-T panel deliberately separates compact browsing from surfaced evidence: ordinary fact rows use a 50-character value preview, while a row bubbled by runtime reference, explicit reasoning citation, or context-loaded state renders its full value. The storage value is never truncated; this is projection-only behavior. + +The panel exposes six navigation tabs: five memory views โ€” `FRAME` (live runtime-memory snapshots), `ACTIVE`, `DELAYED`, `L-T`, and `FILES` โ€” plus `LOGS`, which is a projection of the disk session archive rather than a memory store. Their shared count control is projected below the active tab; only FRAME exposes previous/next snapshot controls. The temporary unprocessed-facts projection is intentionally omitted from the tab bar. Delayed rows use the same floating detail-card primitive for a bounded report preview (title/summary, creation time, tags, report ID, anchor/fact IDs, and up to 200 body characters). Unpinning a Delayed report emits the shared `memory_unpinned` logger event instead of becoming an invisible panel-only mutation. LOGS titles come from protected FRAME `session_title`; list rows update from successful disk commits, hover previews are fetched lazily, short-click restores, and the shared hold-delete gesture removes the archive. + +L-T facts are partitioned into Live Avatar lanes of at most 100 records; additional facts create additional outer L-T rings with a small radius step. The Active ring is laid out relative to the resulting outermost L-T radius so it remains between L-T and persistent files. Memory-row hover reuses the existing avatar hover-zoom/reference path rather than rebuilding ring state. + +Completed assistant messages expose an explicit `Copy all` control under the avatar/message host. The old invisible bubble gesture surface is removed; answer-rating code remains present but release-disabled. + +L-T merge telemetry keeps a structured `lt_merge_applied` trace with operation details. Console Apply/Show inspection renders update/create/merge/ignore rows and token-level diffs from the structured trace; legacy human-text parsing is fallback compatibility only. + +FRAME summarizer logging uses one `[MEMORY:FRAME]` card (`extract -> apply`, plus `show`) per request. The request uses the non-streaming Service API; clicking the pending extract label opens the request immediately. After application, `show` and `apply` open `FRAME SUMMARIZER RESPONSE` with one `EXTRACTED FRAME` context-style key/value card. Failed, skipped, and cancelled requests terminate the pending state without presenting a successful apply. L-T extraction and merge request labels are likewise inspectable while pending. + +Session-action logger rows are also a projection of structured history. The compact logger keeps the most recent five items in chronological order with their original numbering and reuses the existing attached-files header/button primitive for `FULL`. JIN_COLOR parts render one swatch per applied color and expose the normalized hex on hover; bootstrap must preserve the `colors` payload for this to work after reload. Runtime-action bubble details are retained across counter-only updates so a count refresh cannot erase existing hover metadata. + +JIN visual-action chat bubbles are enabled in this snapshot (`ENABLE_JIN_VISUAL_ACTION_BUBBLES=true`). Each applied visual marker keeps its own action bubble/display ID; counter-only telemetry does not aggregate those markers into one bubble. Parsing, execution, avatar updates, raw event persistence, and Session Actions logging remain independent of that UI flag. + +Color has one visual transition owner in the avatar API. The initial bootstrap application consumes the one 2000 ms transition; later/live JIN_COLOR applications use 333 ms. The API writes the same temporary duration to avatar-center and scene-tint CSS variables before applying the color, so both projections move together. The old color queue and separate bootstrap tint-shift helper are absent. + +Normal session bootstrap resolves color from the disk-owned session snapshot/raw action trail into server `RuntimeContext`, then applies it once through `session_actions_update` with `bootstrap_restore=true`. The earlier browser-checkpoint color is not a reload authority, and there is no client-side resolver scanning competing sources. + +### Chat bubble skins and context-pressure scaffold + +Chat bubbles currently support `dark`, `light`, and `bamboo` skins through `ui/static/js/win95-theme.js` and `ui/static/css/chat-bamboo.css`. Normal theme defaults to `dark`; Win95 defaults to `light`. `jin_bubble_skin` stores the selected skin and `jin_bubble_skin_pinned` records whether it should survive theme changes. Choosing the current theme default leaves the skin unpinned; choosing a different skin pins it. The Context/trace settings surface exposes all three choices. + +The Live Avatar scaffold is also part of the context-pressure UI. `runtime-panel.js` writes `--jin-context-pressure-color` and `--jin-context-pressure-percent` from the Brain context meter (hue 150 -> 15 as usage goes 0 -> 100). Static scaffold circles do not rotate and use that pressure color. Sixteen rays breathe on a fixed 30-second cycle, fully fading to zero; pressure raises the active subset from 3 toward 7 rays and raises peak opacity from 0.10 toward 0.70 before each ray's local-strength multiplier. Center hide fades scaffold/runtime/memory/file layers for 420 ms and then switches them to dormant display/animation state; the central light remains visible. + +### Header auto-hide + +`ui/static/js/header-autohide.js` currently uses: + +- reveal-zone height = 2 x measured header height; +- show debounce = **333 ms** in this snapshot; +- hide delay = **1000 ms**; +- panel occlusion logic so moving over panels/avatar does not trigger the reveal path incorrectly. + +The product intent recorded on 2026-08-21 was approximately 250 ms reveal debounce. The code/intention mismatch is tracked in `JIN_CURRENT_STATE.md`; do not silently change it while working on an unrelated task. + +### Visual rule + +New UI states must reuse the closest existing JIN primitive. The UI deliberately avoids generic SaaS success/error visual language, arbitrary new glow colors, and decorative blur. + +--- + +## 13. Extension rules + +### New runtime action + +Start at `contracts/*.json`, then connect normalization/handler logic in `utils/actions/`, guard semantics if necessary, event/tool-result/follow-up behavior, and tests. + +### New durable state + +Define exactly one canonical owner, stable identity, persistence location, bootstrap/hydration path, mutation path, reconciliation rules, and browser projection. + +### New model context source + +Keep canonical state outside the prompt builder. Serialize it in `utils/context/` or `rules/brain_context_builder.py` at a deliberate position. + +### New UI behavior + +Use existing semantic IDs/events and existing CSS/DOM primitives first. New visual language requires explicit justification. + +--- + +## 14. Known architectural traps + +Do not infer current architecture from compatibility/history alone: + +- `USE_SERVICE_AS_BRAIN`, archived `RUNTIME_MODE=SERVICE`, archived `role=service`, or old `[SERVICE]` logger-card code; +- `SAVE_SESSION` references in tests/log parsing; +- comments/log filters mentioning the old numbered-layer glow names; +- pre-L3-removal storage migration keys/fields; +- stale repository indexes or historical test assumptions; +- historical field names like `runtime_l3_session_memory`; +- the name `find_latest_completed_session_restore_payload()`; current selection is newest real USER move, including USER-only interruption; +- treating the page-local checkpoint/projection API as reload authority, or any projection write as permission to advance disk `saved_at`; +- using runtime `saved_at` to decide whether copied dialogue is current; +- treating a newly opened runtime ID as the newest conversation before a real USER move; +- assuming an empty collection always means "missing" during archive enrichment; +- sanitizing session actions down to text while dropping structured UI metadata such as `parts[].colors`. +- adding a separate JIN color key/resolver/queue instead of reconciling the common checkpoint and raw action log. + +The verified filesystem has no active L2/L3 modules and no current `SAVE_SESSION` contract. + +For the exact transition/conflict list, see `docs/JIN_CURRENT_STATE.md`. diff --git a/docs/JIN_CURRENT_STATE.md b/docs/JIN_CURRENT_STATE.md new file mode 100644 index 00000000..1595639c --- /dev/null +++ b/docs/JIN_CURRENT_STATE.md @@ -0,0 +1,700 @@ +# JIN Core Engine โ€” Current State / Migration Notes + +**Snapshot inspected:** `jin_core(20261001-090403).zip`

Executive state + +The production runtime is on the post-L2/L3, Brain-first architecture and the root documentation is now synchronized with it. + +Current high-signal state: + +- transport continuity: the physical WebSocket no longer owns/cancels the runtime queue. `RuntimeContext.runtime_transport` retains accepted work and unacknowledged output in process RAM; a soft reconnect attaches to that live task and does not re-upload stale memory stores. Explicit page departure retires the runtime, while an unexplained disconnect has a 600-second reconnect grace before cancellation/release.

Remaining production references are compatibility comments/log filters/storage migration residue, not active modules; +- the panel exposes five memory views (`FRAME`, `ACTIVE`, `DELAYED`, `L-T`, `FILES`) plus the `LOGS` session-archive projection; the internal Facts Memory candidate buffer is not a user-facing tab; +- FRAME is the canonical name for live runtime memory across documentation, implementation modules, state fields, events, the pending journal, UI identifiers, and tests. +- direct value editing is live for the latest FRAME, Active conditions/value, and L-T fact values; keys/IDs remain read-only, drafts are page-local until acknowledged, and Active/L-T edits surface `updated_at`. +- the L-T panel defaults to active facts, can toggle `show all` to reveal report-absorbed facts in normal sort order, and keeps report-linked fact IDs clickable. +- L-T recall now tracks `mention_count`/`last_mentioned_at`: facts untouched for 24 hours are compacted to 100-character sentence previews in Brain context until JIN references them again. +- pinned outgoing files appear as composer attachment chips; click previews, hold detaches from context without deleting the persistent file. +- Brain recent-message context is adjacent to `` and keeps the newest five pairs in full, with newline/XML normalization but no per-message character crop; +- ordinary Brain turns include the previous successful reasoning block with explicit middle-crop semantics, while follow-ups keep their dedicated reasoning context; +- reload/new-tab continuity is disk-owned (JSONL/runtime events plus saved `frames/` snapshots). Browser cognitive records are page-local projections only: `jin.liveRuntimeMemory.v2` is cleared at page load and the retired durable `jin.sessionCheckpoint.v2` browser value is removed before bootstrap; +- Session CLEAR is a durable tombstone that blocks passive resurrection across already-open tabs until a new USER message is successfully sent; +- `SAVE_SESSION` is not a current runtime-action contract; archived-session restore is handled by the bootstrap/restore path; +- the current action set includes `JIN_REACTION`, internal `RECALL_FACT_CONTEXT`, `CHAT_LOG_SEARCH`, generic skill-gated `CALL_MCP`, and whole-file `ATTACH_FILE_BY_ID`; fact recall, delayed-memory loading, Active deletion, file-by-ID attachment, skill loading, and skill unloading use paired list markers while their internal actions remain singular; +- runtime actions execute in exact model-emitted source order (`prepare -> run` per call); `runtime_order` only orders advertised contracts, and the former visual-sequence collector/stage path is absent; +- `BRAIN_MAX_FOLLOWUPS=0` is unlimited; positive values cap executable workflow ticks and then allow one final response tick with actions disabled.

Do not re-add a model action just to make old tests pass. + +--- + +## 5. Current action contract set + +`CHAT_LOG_SEARCH` now adds local literal chat-history search with OR queries, +source/date/time filters, attachment metadata and anchored reasoning excerpts. +It uses the existing action/result/error/bubble pipeline and does not require +web-search credentials. Raw archive restore accepts this structured runtime +result and its T ID; disk bootstrap preserves full matched messages without +slicing the result JSON at 32K. Details: [CHAT_LOG_SEARCH.md](CHAT_LOG_SEARCH.md). + +Search verification (2026-09-08): 20 focused search, unclosed-action and readable +tool-result tests pass; the headless Edge socket-to-DOM test and existing tool-ID +history/checkpoint JS test pass. Extending the run with archived restore and +bootstrap-tail tests yields 54/58 passing. The four archived-restore failures +also reproduce with the original changed reader functions and original action +flags: old `runtimeMemory.saved_at` client expectation, one-shot restore prompt, +the then-current restore-dialog bound, and bounded URL-restore UI tail. Those were historical failures from the 2026-09-08 search work; the current shared dialogue bound is five pairs and the restore/follow-up prompt ordering has since changed. Older cleanup tests may still name removed function/log strings. This paragraph is historical evidence, not the current verification status. + +The contract assembler currently advertises these actions in `runtime_order` order (this is prompt-contract ordering, not execution priority): + +```text +DEEP_WEB_SEARCH +WEB_SEARCH +CLEAN_TOOL_RESULTS +JIN_COLOR +JIN_REACTION +JIN_SIZE +JIN_POSITION +JIN_SPEED +UPDATE_LT_FACTS +RECALL_FACT_CONTEXT +CHAT_LOG_SEARCH +LOAD_SKILL +UNLOAD_SKILL +ASSET_ACTION +POSTING_BOARD +CALL_MCP +LIST_ALL_USER_SHARED_FILES +ATTACH_FILE_CONTENT +ATTACH_FILE_BY_ID +SAVE_DELAYED_MEMORY +LOAD_DELAYED_MEMORY +SAVE_ACTIVE_MEMORY +DELETE_ACTIVE_MEMORY +``` + +`LOAD_SKILL` and `UNLOAD_SKILL` are singular internal runtime action names. Their canonical public/model markers are ` skill1, skill2 ` and ` skill1, skill2 `; each valid comma-separated item becomes one ordered internal action. + +`utils/actions/dispatcher.py` is source-ordered: it fully prepares and runs each emitted call before touching the next one. The action registry has no execution stage field. Every concrete contract carries a separate `schema` string array before `rules`; `contracts/rules_assembler.py::get_runtime_action_schema()` feeds both model-facing contract text and failed-action diagnostics. Failed tool results are rendered as readable text (status/reason, supplied payload when relevant, `Correct action schema:`), and `ACTION_FAILURE_FOLLOWUP_MESSAGE` explicitly tells Brain not to assume the failed action completed. + +`POSTING_BOARD` is a native action exposed only after ` posting_board `. The side skill documents the minimal inner actions (`feed`, `inbox`, `read`, `search`, `post`, `reply`, `ack`, `delete`); the runtime executes them against Get Posting Board and records the exact public request preview plus response as a runtime tool result. Chat bubbles use one stable action ID from running to completed/failed, then fade and become clickable for the reused trace modal. Session Actions intentionally keep only compact markers such as `POSTING_BOARD: action:feed` or `POSTING_BOARD: action:post - failed`; request/response bodies stay out of session-action text. Public writes, including deletion, are blocked when persistent writes are restricted, while board reads remain available. `delete` targets one owned message by exact `post_id`; deleting a root removes the entire thread, so the skill requires explicit authorization and warns Brain to preserve roots unless whole-thread deletion is intended. The bearer token is resolved through the environment override helper from `GETPOSTINGBOARD_API_KEY` (or its supported `JIN_GETPOSTINGBOARD_API_KEY` alias) and is never projected into model/UI context. + +`CALL_MCP` is generic and skill-gated. A loaded skill with valid `...` config is discovered with `tools/list`; the live server/tool schema is appended only to that loaded in-memory skill as ``, and then `CALL_MCP` can route `{skill, tool, arguments}` to an exact loaded skill/tool. One MCP connection is kept per loaded skill across follow-ups, calls are excluded from result reuse, and unload/runtime retirement closes the connection. Returned image blocks are capped at 20 MiB each, stored as pinned JIN files, stripped of base64, and attached to the current sequence so the next Brain tick can inspect them. Generic MCP bubbles open a structured request/result modal; `get_viewport_screenshot` reuses the standard attachment preview. Full contract: [MCP_SKILLS.md](MCP_SKILLS.md). + +The mapped Brain feature flags in `rules/brain_context_builder.py` are enabled. `WEB_SEARCH` and `DEEP_WEB_SEARCH` are then filtered again by `settings.CAN_SEARCH`, so they are not model-visible unless provider `serper` has a non-empty, non-placeholder process-environment key. `jl.ps1` imports an ignored repository-root `.env` before resolving configuration and starting Python; `.env.example` documents the supported secret names without containing credentials. Direct `python app.py` starts still rely on variables exported by the calling shell. The local availability check intentionally does not impose an invented key-length/shape regex; Serper remains the credential authority. + +Canonical short action syntax is paired: ` query `, +` id1, id2 `, +` id1, id2 `, and +` id1, id2 `. A model-issued delayed +load records each report as a separately identified tool result and does not +populate ``. Only explicit user pinning populates that +block. `UNLOAD_DELAYED_MEMORY` is no longer a model-facing contract; tool-result +cleanup is the removal path. + +`CLEAN_TOOL_RESULTS` is a strict paired-block action. The canonical targeted form is ` T1, T2, T3 `; one or more exact `T` IDs are listed in the body, separated by commas. Targeted cleanup validates the whole list before mutating state, so an invalid or missing ID removes nothing. An empty `` block performs the explicit full cleanup, including legacy ID-less results. The old bare marker and `` inline form are no longer executable syntax. + +`JIN_SIZE` contract version 2 currently advertises ` w:120 h:120 `; a single value such as ` 120px ` means square size. Positive decimal values may use `px`, `vw`, `vh`, or `%`, with unitless values defaulting to `px`. The backend preserves those units in the canonical action payload. The browser resolves them against the live viewport when the action is applied: width `%` uses viewport width, height `%` uses viewport height, `vw` always uses viewport width, and `vh` always uses viewport height. The applied/clamped room geometry is then persisted in pixels. Unsupported suffixes such as `em` are rejected instead of being silently reinterpreted as pixels. + +`JIN_COLOR` contract version 2 likewise advertises ` #00f2ff `. Both actions put payload in a paired tag body. Localized parsing still accepts old colon/space inline variants, but those are not model-facing syntax. Current parser/formatter tests require ordinary `before`/`after` answer text to survive marker removal and cover split-chunk completion. + +The runtime now also has a strict response-prefix fallback for missing angle brackets. Before visible answer text starts, an exact standalone `ACTION_NAME: payload` line may execute only for the current eligible set: `ATTACH_FILE_CONTENT` plus `JIN_COLOR`, `JIN_REACTION`, `JIN_SIZE`, `JIN_POSITION`, and `JIN_SPEED`. Paired/block actions such as `WEB_SEARCH`, `LOAD_SKILL`, `LOAD_DELAYED_MEMORY`, and `RECALL_FACT_CONTEXT` remain non-executable when written only as a bare internal action name. Invalid or prose-like payloads stay visible and immediately end the bare fallback; later bare lines stay text, while ordinary `<...>` markers continue to work. Streaming holds an unterminated candidate until newline or final flush, and accepted standalone action lines are removed without leaving a blank line. + +The whole-response extractor and streaming filter now share the same `allow_bare_prefix_fallback` behavior/default, so chunked and non-stream parsing no longer disagree on this case. + +JIN visual actions no longer use a dedicated sequence collector. Color/size/reaction/position/speed calls are ordinary actions executed in exact model-emitted order. Color and size filtering removes only a true no-op against the last applied value in the same runtime-message scope; alternation remains valid, and the same value can be requested again in another message. + +--- + +## 6. Delayed Memory transition + +### Current canonical contract + +`contracts/save_delayed_memory.json` is version 5 and requires a JSON body inside ` ... `. + +Required fields: + +- `title` +- `summary` +- `tags` +- `body` + +Relationship fields: + +- `anchor_lt_facts_ids` +- `lt_facts_ids` +- `attachments_ids` + +The contract explicitly requires exact existing IDs and `anchor_lt_facts_ids` as a subset of `lt_facts_ids`. + +### Legacy + +Old key/value bodies and `` may still be normalized by compatibility code/data history but must not be documented as the preferred form. + +--- + +## 7. Active Memory transition + +### Current model-facing contract + +`SAVE_ACTIVE_MEMORY` version 5 creates or updates Active Memory: + +```json +{"conditions":"CONDITIONS","custom_field_name":"VALUE"} +``` + +When `id` is present, the same contract updates the existing record: + +```json +{"id":"AM-abcdef","conditions":"NEW CONDITIONS","existing_custom_field":"NEW_VALUE"} +``` + +The create parser now treats custom fields as explicit JSON structure only. A non-JSON body is preserved as the complete `conditions` value; parenthesized prose such as `(date: tomorrow)` is no longer reinterpreted as a custom field. JSON custom fields are capped at three after normalized duplicate keys use last-value-wins behavior. + +The model-facing create/update boundary is now one paired `...` block. Root `id` switches the action into update mode; without `id`, it creates. Update fields stay flat at the JSON root. `conditions` can always be updated; other keys must be exact custom fields already declared on the target record. + +Only the flat JSON shape shown above is accepted for Active Memory updates. Old `UPDATE_ACTIVE_MEMORY` payload shapes and old six-character IDs are rejected. + +### Current internal representation + +Active records are still stored/transported in a string-oriented record format with metadata suffixes. Prompt assembly refreshes metadata, removes paused items, and may rank the prompt view by lexical/context relevance. + +### Risk + +Do not โ€œfinish the migrationโ€ by replacing the internal storage shape in an unrelated task. The structured JSON action boundary is settled separately from the string-oriented internal record representation; storage migration needs its own end-to-end plan. + +--- + +## 8. Prompt assembly โ€” verified order + +Current `build_brain_context()` order is intentionally structured. Important anchors: + +- ordinary turns put `RUNTIME_SETTINGS` first when non-empty, then optional `CONCERNS` and trusted runtime XML; the former user-waiting and separate context-usage prompt blocks are removed; +- at 50%+ previous-answer context usage, `CONCERNS` shows the percentage; with nonempty tool results it appends `check and clean redundant tool results`; +- tool results precede Session Actions, attached-file/Delayed inventories, and the always-present `SKILLS_LIST`; loaded skill bodies are part of the tool-results projection rather than a second independent prompt section; +- the runtime-context group orders Active Memory before FRAME, and `` immediately after ``; loaded Delayed/L-T follow later in the same group; +- ordinary `` keeps the newest five pairs without per-message character cropping; physical newlines become literal `\n` and XML-sensitive characters are escaped; +- ordinary initial turns include previous successful reasoning in ``; blocks over 2000 characters keep the first and last 25% with an explicit middle-cut marker; +- archived restore priming instead begins with inherited ``, then carried reasoning evidence, then ``; `RUNTIME_SETTINGS` and the normal live scaffolding come after that continuity preamble; +- action/recovery follow-ups likewise move visible dialogue and carried reasoning ahead of ``, then append failure/recovery/action history/current concerns/tool results and the base prompt without duplicating those continuity blocks; +- action contracts remain present even on restore ticks, subject to effective capability filtering; +- `WEB_SEARCH` and `DEEP_WEB_SEARCH` disappear when `settings.CAN_SEARCH` is false; +- identity and loop rules remain at the bottom of the base prompt. + +Any prompt-order change can alter behavior materially. Do not reorder sections for aesthetics. + +--- + +## 9. Bootstrap / archived restore โ€” verified behavior + +### 9.1 Server-owned bootstrap and reconnect (D057, 2026-09-26) + +Normal connection sends an empty `session_bootstrap` request. The server selects the newest surviving real USER archive, ignoring every browser snapshot field, timestamp and owner ID. An explicit archive checkout sends only `archived_session_restore` and `source_session_id`; the server rereads that archive. Read errors are surfaced, never used as permission to import browser state. + +The existing archive builder combines USER/JIN rows and reasoning, structured action history, server `session_checkpoint` events and later cleanup/tool-result events. Latest `frames/_frame_.txt` wins over the earlier prompt's FRAME. New frame files embed the complete snapshot metadata beside the readable FRAME; legacy files retain their text fallback. Explicit empty FRAME and tool inventories stay empty. A single server `bootstrap_state` response feeds the existing UI projection, followed by the established FRAME/actions/chat-tail events and hidden continuation tick. + +`RuntimeContext` remains the live owner. Soft reconnect with a surviving transport sends no browser state. After server restart, the same page requests disk bootstrap again. `runtime_resume` snapshots are ignored. Active/Delayed/Facts/L-T remain disk-profile-owned; automatic legacy browser Facts imports are disabled. + +Normal cognitive caches use page RAM, with the existing ephemeral FRAME record cleared on every page load. The `jin.sessionCheckpoint.v2` and older durable cognitive records are retired and removed on startup, without migrating their contents. UI preferences remain in localStorage. An in-page checkpoint API remains for existing projection callers; it cannot become a reload source. + +### 9.2 Lifecycle, clear and disk persistence + +D049 remains unchanged: greeting-only tabs are not saved continuation sessions; a real USER send qualifies immediately, including interrupted USER-only/action-only turns. Latest-source selection and explicit archive restore retain their existing separate semantics. Dialogue/reasoning keep original timestamps and the five-USER-move bound. + +The transport archives the same server `session_snapshot` projection it emits, only after a session log exists. New tool results are recorded at the canonical tool-result writer; cleanup events preserve the exact remaining inventory and monotonic tool ID sequence. FRAME keeps its existing deferred writer. None of these writers can recreate a physically deleted materialized archive. + +Session CLEAR writes an atomic `logs/.continuation-cleared.json` barrier of USER row counts, without deleting archives. Later passive output, room updates or other tabs cannot lift the barrier. A newly logged USER row can. This avoids timestamp precision races and keeps explicit archive checkout available. + +### 9.5 Normal bootstrap chat tail + +The backend emits at most five newest real USER moves from `runtime_recent_turns`, with JIN, reasoning, and original timestamps where available. The browser rebuilds them through existing chat primitives, strips synthetic attached-context boilerplate from USER display, keeps USER-only moves without an empty BR bubble, appends the current date/session divider, and activates the live viewport at that divider. Explicit archived restore suppresses this duplicate normal-bootstrap tail. + +### 9.6 Archived restore + +Current restore code deliberately prevents the โ€œdouble applyโ€ class of bugs. + +Verified behavior: + +- archived visible dialogue is rebuilt from logs; +- the newest five real USER moves are used for the restore context in chronological order, with empty JIN retained where the turn was interrupted/action-only; +- no separate restore-reasoning dump is generated; the hidden bootstrap prompt instead carries the prior reasoning through `` after `` and before the mandatory automatic-restore notification; +- loaded Delayed IDs and attached files are staged; room/avatar state is restored by bootstrap and is not replayed as runtime actions; +- restore Brain response occurs before normal resource reactivation; +- `BrainNode.replay_session_restore_resource_actions()` consumes the staged Delayed/file envelope and applies only those resources through the real action dispatcher; +- WebSocket tail only clears defensive state and explicitly warns against mutating/emitting resource state a second time. + +This is a strong architectural clue for future restore fixes: find duplicate writers before adding another apply. + +--- + +## 10. L-T / Facts Memory current path + +### Facts Memory + +Browser runtime storage creates per-session facts-memory candidate buckets from persisted runtime snapshots and synchronizes them to backend with `facts_memory_store_sync`. + +### L-T + +L-T has a real staged pipeline with: + +- pending candidate collection; +- extraction; +- merge/rebase; +- validation/recovery/backoff; +- explicit-edit protection; +- report-reference remapping; +- archive/anchor logic; +- delete/restore; +- file-store persistence. + +### L-T UI projection + +Ordinary L-T rows display a 50-character value preview. When a fact is bubbled because it was referenced, explicitly cited from reasoning, or loaded into context, the row displays the complete value with no preview truncation. This does not mutate or reorder the stored fact; it is a visibility rule for surfaced evidence. + +The default L-T panel view excludes facts absorbed by Delayed reports unless they are currently context-loaded. Clicking the L-T count toggles `show all` / `show active`; the all view uses the same normal numeric fact sorting rather than appending hidden rows at the bottom. A fact linked to a Delayed report renders its number as the existing report-link control and opens that report modal. Anchor facts remain visible rather than being classified as absorbed. + +### Recall / mention decay + +Canonical L-T facts carry `mention_count` and `last_mentioned_at`. One valid fact reference from JIN reasoning or visible output increments the canonical fact at most once per turn. The timestamp is persisted and exposed in hover metadata. A background log backfill repairs historical mention dates without overwriting a newer live mention. + +Brain context uses the full fact value while its last mention/update/create timestamp is newer than 24 hours. Once stale, each sentence is compacted to at most 100 characters. Referencing the fact refreshes `last_mentioned_at`, so subsequent turns can receive the full value again. + +### Scheduling + +L-T background work is started by browser `lt_memory_idle_tick`. Server refuses to begin it while a foreground task is active or the pending request queue is non-empty. + +This is the current performance/ordering contract. Do not move L-T onto every foreground turn to โ€œmake facts fasterโ€ without proving latency and ordering behavior. + +--- + +## 11. Memory Attention status + +The metabolism subsystem has been removed. `runtime/memory_attention.py` retains only prompt-local retrieval behavior: + +- Active lexical/context relevance; +- Delayed bubble matching; +- L-T 1โ€“3 fact focus. + +There is no metabolic SERVICE pass, homeostat, learned association state, temperature modulation, Brain instruction, FRAME strength bias, significance persistence, bootstrap chemistry, logger trace, or avatar chemistry. Historical significance fields are discarded while normalizing old Active/Facts/L-T records. + +### Not proven + +The older concept of a full nightly self-review cycle that reads cropped reasoning/context and emits a morning cleanup report is **not proven complete** by this snapshot. Do not describe it as finished architecture without finding the actual scheduler/storage/report path; Memory Attention is unrelated to that cycle. + +--- + +## 12. Anonymous room status + +Anonymous mode is now explicit JIN behavior and does not attempt to detect Chrome/Incognito/private browsing. Long-pressing the avatar opens a fresh anonymous room with a generated `_anon` session id. + +Backend `runtime/anonymous_mode.py` currently: + +- marks unrelated runtime persistent side effects restricted; +- stores Active, Delayed, Facts Memory candidates, and L-T in the normal memory folders with `_anon.json` filenames; +- shares those anonymous memory files across concurrently open anonymous rooms and deletes them after the last anonymous room closes; +- allows `UPDATE_LT_FACTS` and `SAVE_DELAYED_MEMORY` only inside that anonymous file-backed profile; +- preserves Delayed reports and loaded bodies on a soft WebSocket reconnect; +- blocks persistent asset-write actions; +- prevents anonymous FRAME pending journals under `memory/frame`; +- keeps chat/reasoning logging under ordinary `logs/` with the `_anon` session suffix. + +Browser `sessionStorage` still carries tab-local anonymous room/bootstrap state, but Active/L-T/Delayed/Facts Memory are server file-owned and browser values are projections. The normal profile's durable memory is never used to seed an anonymous room. Normal restore/bootstrap and L-T log-freshness scans skip `_anon` logs. + +--- + +## 13. UI / visual state mismatches and active decisions + +### 13.1 Header reveal timing + +Current `ui/static/js/header-autohide.js`: + +```text +SHOW_DELAY_MS = 333 +HIDE_DELAY_MS = 1000 +``` + +Owner intent from the latest UX pass was approximately 250 ms reveal and 1 s hide. + +**State:** implementation/product-intent mismatch. Do not fix incidentally. + +### 13.2 FRAME naming + +The live runtime-memory view is `FRAME`, and FRAME is the canonical documentation/product/implementation name for this live state. FRAME integration detects the current user-message language for values, while keys remain structural English `snake_case`. + +The panel always shows `FRAME`, `ACTIVE`, `DELAYED`, `L-T`, and `FILES`, even when a non-FRAME view is empty. The shared counter moves below the selected tab; FRAME keeps the existing snapshot arrows while the other tabs show only their record count. The temporary unprocessed-facts projection is not exposed as a tab. + +### 13.3 Visual reuse + +Hard owner rule remains active: reuse existing visual primitives; no invented highlight colors/glows/badges/strips unless explicitly approved. + +### 13.4 Loaded vs referenced highlight + +Strong loaded-context highlighting and weak ID-reference highlighting are separate semantics. Opening a modal is not a context load. This area has had regressions and must be traced through both panel state and avatar state. + +### 13.5 Session Actions logger + +The compact logger now shows the most recent five actions in chronological order while retaining their original history numbering; `FULL` uses the existing attached-files header/button visual primitive rather than a new style. JIN_COLOR entries depend on `parts[].colors` for the color square and hex hover, so that metadata is part of the bootstrap contract, not disposable presentation data. + +Validator/reasoning-loop and context/output-limit entries are emitted immediately when the interruption is detected, before automatic recovery/follow-up. `context_overflow` is included in context-limit finish reasons. Provider/preflight overflow errors and native `chat.end`/`stop` with a full provider-reported context now use that path too; context/output-limit history entries remain separate rows. Context overflow uses `FOLLOW_UP_CONTEXT_OVERFLOW_MESSAGE` to request immediate targeted `CLEAN_TOOL_RESULTS`, without the ordinary deep-reasoning follow-up notice or its last-action/result suffix. Output-only limits retain their existing continuation. Recovery still obeys the workflow follow-up budget; no tool results are automatically deleted, and a provider must accept the recovery prompt for model-directed cleanup to run. This timing is intentional: the logger should reflect the loop while it is happening, not only after the final JIN response. + +### 13.6 Runtime action hover stability + +Runtime-action bubbles persist their detail in DOM dataset state. Counter-only updates reuse the existing detail/title instead of clearing it, so an aggregate count refresh cannot erase hover information. + +### 13.7 Interaction fixes landed in this snapshot + +- the latest manually chosen reasoning collapsed/expanded preference is persisted and reused by new reasoning blocks; +- live-turn top-lock releases once the user turn reaches the viewport bottom, after which normal overflow autoscroll can resume; +- clicking usable form padding focuses the JIN user input; +- answer-rating implementation remains in the client but is release-gated off; the old invisible bubble double-click/hold utility surface has been removed, and completed assistant output instead exposes an explicit `Copy all` button under the avatar/message host; +- Win95 theme localStorage reads/writes are guarded so restricted storage contexts do not break theme switching. +- Win95 renders disabled memory-sequence labels/arrows as flat status text and keeps the avatar progress border square; these are theme-specific projections, not new runtime states. + +### 13.8 Chat skins and avatar context pressure + +`win95-theme.js` exposes three bubble skins: `dark`, `light`, and `bamboo`. Normal theme defaults to dark and Win95 to light. `jin_bubble_skin` stores the current choice; `jin_bubble_skin_pinned` means the user's explicit non-default choice survives a theme switch. The Context/trace settings UI renders the same three options. + +`runtime-panel.js` synchronizes the Brain context meter into `--jin-context-pressure-color` and `--jin-context-pressure-percent`. Static scaffold circles do not rotate; their stroke and the ray stroke use the pressure color. Sixteen rays breathe to zero on a 30-second cycle. Pressure selects roughly 3..7 stronger rays and raises their maximum unmultiplied opacity from 0.10 at empty context to 0.70 at full context. The center toggle fades scaffold, runtime/memory rings, file ring/dots, and center rings; after the 420 ms fade the hidden layers enter `is-memory-layers-dormant`, which removes them from display and disables their orbit/reasoning animations. The center light remains visible. + +### 13.9 Direct memory editing + +Double-clicking a FRAME, Active, or L-T row converts the existing details tooltip into a fixed editor rather than opening a separate styling primitive. Only values are editable. FRAME accepts edits only on the newest snapshot; Active edits conditions/value while preserving custom fields, pause status, IDs, and other metadata; L-T edits only the durable fact value and preserves identity/provenance. Keys are never editable. + +Editor drafts are page-local. The checkmark sends `memory_value_edit` with `expected_value`; conflicting/stale writes are rejected without discarding the draft, and FRAME writes are additionally rejected while the live FRAME/foreground writer is busy. FRAME row deletion uses the same busy guard; because the browser applies long-hold deletion optimistically, a rejected delete immediately re-emits the authoritative latest FRAME snapshot. Active edits stay writable during Brain/FRAME work because they mutate the independent `active_memory_records` store. The rollback arrow restores the last acknowledged value. Active and L-T successful edits create/update `updated_at` immediately in the open tooltip. Active pause/resume panel writes synchronize `active_memory_store_sync` before the local changed event so a later edit cannot revive stale pause state. + +### 13.10 Composer attachment chips + +Pinned files attached to the outgoing message are rendered immediately to the left of the input as compact chips using the existing attachment preview primitive. New chips animate in through the established composer style. Click opens preview; hold detaches/unpins the file from the outgoing context. The persistent file remains in the library, and attaching/detaching no longer expands Console as a side effect. + +### 13.11 Delayed/L-T inspection and Live Avatar scaling + +Delayed panel rows now expose the shared floating detail card with title/summary, creation time, tags, report ID, anchor/fact IDs, and a body preview capped at 200 characters. Unpinning a report produces the shared `memory_unpinned` logger card/state rather than only changing the panel. + +L-T merge Apply/Show inspection prefers the structured `lt_merge_applied.operation_details` trace and renders per-operation update/create/merge/ignore rows with token-level diffs; legacy text parsing remains fallback compatibility. Live Avatar L-T facts are split into lanes of at most 100 facts, with additional outer rings as needed. Active Memory is positioned outside the outermost L-T ring but inside the file ring. Hovering a memory row reuses the avatar memory-row zoom/highlight state. + +### 13.12 Runtime model status/switch + +The BRAIN/SERVICE status modal reads role-specific LM Studio metadata. Where the role is available, its model field opens the model picker; selection POSTs the model plus remembered load configuration to `/api/runtime-model/switch`, then reconciles from `/api/status`. This switches the physical model backing the role and does not change the Brain-first routing invariant. + +### 13.13 Normal bootstrap tail + +Normal bootstrap renders the inherited five-USER-move tail above a date-labelled current-session divider and places the live viewport at the divider. Saved reasoning is rendered through the existing reasoning bubble path. A USER-only interrupted/action-only move remains visible without a blank BR bubble. Archived restore has its own renderer and blocks this path. + +### 13.14 JIN color projection + +JIN visual-action chat bubbles are enabled in this snapshot (`ENABLE_JIN_VISUAL_ACTION_BUBBLES=true`). Each applied marker gets its own display ID/bubble; counter-only telemetry does not collapse markers into one aggregate bubble. Parsing, execution, avatar updates, raw action logging, and Session Actions remain live regardless of this UI projection flag. + +Avatar center and scene tint now share one transition duration variable set. First bootstrap color uses 2000 ms once; all later/live color changes use 333 ms. There is no center-color queue, secondary bootstrap tint shift, or separate client color resolver in this snapshot. + +### 13.15 MCP runtime projection + +Session Actions renders `CALL_MCP` identity inline as `skill / tool` instead of hiding the useful target in title-hover metadata. Runtime bubbles retain the parsed request, result, and raw payload. Generic MCP calls open the structured MCP trace modal with fielded arguments/result data; `get_viewport_screenshot` binds the returned hydrated image to the shared attachment hover/click preview instead of inventing a second image viewer. + +--- + +## 14. Verification status for this exact snapshot + +The 2026-10-01 documentation sync uses `jin_core(20261001-090403).zip` as the source baseline. The audit traced the live action registry/dispatcher/contracts, launcher modes, disk bootstrap/restore ownership, FRAME session titles, LOGS list/preview/live-update/delete behavior, and current browser projection boundaries. Historical verification notes below this numbered current-state section remain dated history and must not be read as the status of this snapshot. + +Repository-wide verification for this exact snapshot is green: `python -m tests.run_unittest` ran **1386 tests in 19.467s**, with **OK (skipped=9)**. The earlier discovery blocker around the removed visual-sequence collector is no longer present; `tests/runtime_actions/test_jin_color_bootstrap_persistence.py` now targets `utils.actions.jin_visual_actions`. + +The browser-client aggregate command was also attempted in the documentation environment, but Node Playwright/Edge integration is unavailable there, so `python -m tests.run_browser_client_tests` exits with the harness dependency message rather than exercising browser tests. Do not treat that as a browser green or a product failure. + +--- + +## 15. Documentation status + +As of this snapshot, the documentation set has been synchronized with the production architecture: + +- root `README.md` describes FRAME/L-T/Active/Delayed/Files plus the LOGS archive projection instead of the old numbered four-layer model; +- README model-role/setup/configuration text describes Brain as the only foreground route and Service as optional/dedicated background execution with Brain fallback; +- `AGENTS.md` records the same routing invariant and explicitly classifies old `USE_SERVICE_AS_BRAIN` / archived Service labels as compatibility; +- `docs/JIN_ARCHITECTURE.md`, `docs/JIN_DECISIONS.md`, and this file use the 2026-10-01 inspected source as the Brain-first/disk-bootstrap/FRAME/L-T baseline and include current LOGS/session-title behavior alongside the action, follow-up, MCP, memory-edit, recall, L-T-view, and attachment contracts. + +There is no root `ARCHITECTURE.md` in the inspected archive. `docs/JIN_ARCHITECTURE.md` is the canonical architecture document. + +--- + +## 16. Repository-index caveat + +Search/index output is navigation evidence, not existence evidence. The inspected archive itself is authoritative for whether a production module is present; this matters especially for removed L2/L3 paths that may remain in stale indexes or historical tests. + +--- + +## 17. Patch-scope / working-tree caveat + +The supplied snapshot does not include `.git`, so repository dirty status cannot be reconstructed from the archive. Treat any pre-existing files or local changes in a real checkout as owner-controlled and do not overwrite or โ€œcleanโ€ them unless the task explicitly includes that scope. + +--- + +## 18. Open / known-unknown items + +Do not present these as settled without fresh code evidence: + +- whether the full night self-review concept is implemented outside the inspected paths; +- which remaining L2/L3-named compatibility fields/readers are still required for real historical data; +- when stale tests that directly mutate `config.USE_SERVICE_AS_BRAIN` or expect `SAVE_SESSION` should be migrated to the Brain-first/checkpoint architecture; +- migrate `tests/runtime_actions/test_jin_color_bootstrap_persistence.py` away from the removed `jin_visual_sequence_actions` collector so repository-wide test discovery can run again; +- final intended internal storage format for Active Memory if the current string-record representation is ever migrated; +- whether reveal debounce should now be restored from 333 ms to the earlier 250 ms preference; +- final canonical list of supported noncanonical action marker aliases after compatibility cleanup; +- which stale tests are still intentional compatibility coverage versus obsolete pre-Brain-first/pre-checkpoint expectations; +- whether every less-common linked-highlight path outside the newly verified L-T/report and Active pause/edit flows is synchronized between panel, prompt-loaded state, and avatar. + +When one of these becomes the task, investigate first and record the resolved decision in `JIN_DECISIONS.md`. + +--- + +## 19. Recommended near-term cleanup order + +When the owner explicitly asks for legacy cleanup: + +1. migrate stale tests away from direct `USE_SERVICE_AS_BRAIN` and old `SAVE_SESSION` assumptions; +2. audit the historical `RUNTIME_MODE=SERVICE` / archived `role=service` readers against real old archives before deleting them; +3. remove the logger's old `[SERVICE]` model-output presentation only after archive/log compatibility is proven unnecessary; +4. audit L2/L3-named UI log filters/comments and pre-L3 storage migration paths against real persisted data; +5. only then delete compatibility adapters/readers that are proven unused. + +Do not combine that cleanup with unrelated runtime behavior patches. + +--- + +## Malformed-action recovery โ€” 2026-09-10 + +Three targeted envelope masks feed the shared failure-follow-up mechanism. `MALFORMED_ACTION` is internal telemetry, not a new model-invokable contract. Its result persists the detected name and original payload; ordered notifications at the top of the next prompt carry the target contract schema. Each occurrence remains independently visible. + +Current 2026-09-24 control semantics supersede the original unlimited-repair note: one malformed repair tick is allowed outside the ordinary `BRAIN_MAX_FOLLOWUPS` budget. If the repair output is malformed again, the sequence stops and runs one final non-executable Brain response tick with runtime actions disabled. Positive ordinary follow-up limits use that same final-response pattern when exhausted; `BRAIN_MAX_FOLLOWUPS=0` means the ordinary workflow is unlimited. + +Thirteen contracts previously had empty `schema` arrays despite the documented schema invariant. Their existing canonical syntax was moved/copied into those arrays so recovery can use the JSON field for every registered action. No action payload semantics or feature flags changed. + + +## Owner bootstrap lifecycle correction โ€” 2026-09-11 + +D049 records the four owner-approved scenarios. The rejected generic JIN-only +bootstrap-rendering workaround has been removed. Normal restore continues to +use actual USER-owned turns and existing per-session boundaries. + +Cancelled startup packets are checked again after FRAME waiting and at +process_message entry; a real USER cancels unfinished startup before queueing. +A pending USER stopped before Brain uses the same interrupted USER commit path, +so it is not silently discarded. Greeting-only checkpoint writes are rejected +also when the normal browser profile has no previous checkpoint. + +The owner supplied MHTML proving the last visible USER/JIN/reasoning pair in +session 7e91148a-2077-454d-a3ec-be6028cd6aec. Its misowned JIN 138 text/reasoning +reference was moved into the existing empty JIN 139 completion, leaving the +USER and its completion timestamp intact. This is a one-time evidence-based +archive repair, not a general text-matching or timestamp-reordering heuristic. +The original log and repair details are in artifacts/bootstrap-repair-2026-09-11. +The older 19:35 session is preserved, as shown in the supplied MHTML. + +Verification covers all four lifecycle scenarios, cancelled startup while +queued/running, USER-only cancellation, clean/existing browser checkpoints, +serialized archive enrichment and the real chat DOM/reasoning toggle. The +current source uses the shared five-pair budget; the old three-pair documentation +mismatch was removed by the 2026-09-17 documentation sync. + +Focused verification: 60 unittest cases pass, both JavaScript lifecycle/boundary +suites pass, and Python/JS syntax plus git diff --check pass. Of 13 additional +function-style bootstrap/checkpoint checks, 12 pass; the raw-color metadata +check fails with KeyError(colors), reproduced against HEAD before these changes. + +## Physical archive deletion correction โ€” 2026-09-11 + +The owner confirmed two distinct photo sends interrupted by LM Studio crashes, +then physical removal of today's logs followed by a server/browser restart. +Normal bootstrap previously returned the browser payload unchanged when its +archive was missing. The persistent localStorage replica therefore restored +both deleted USER rows. New startup responses then created fresh date/session +directories (the inspected 14:33/14:34 JSONL files contain no USER rows). + +Missing archives now invalidate the whole normal-bootstrap replica before +hydration; the newest surviving real USER archive wins regardless of the stale +replica's timestamp. With none surviving the bootstrap is empty. Startup logs +and reasoning stay in RAM until a real USER flushes them in order. Late writers +cannot recreate their deleted materialized session directory. This supersedes +the older test expectation that cancelled startup reasoning creates disk files; +the reasoning remains available in RAM until real activity makes it saveable. + +Verification: 65 targeted unittest cases pass, including physical deletion of +two USER-only photo turns, serialized reload, repeated bootstrap, all four D049 +scenarios, and late-write protection in normal/anonymous mode. Both JS lifecycle +and boundary suites, Python compilation and git diff --check pass. The additional +13 function-style checks retain the one previously established raw-color +KeyError(colors); 12 pass. A real-browser harness using the actual chat scripts +and existing archive selected Sept 10's 7e91148a session, displayed its USER/JIN +pair and reasoning before the 19:38 divider, contained no deleted photo rows, +and kept 14 DOM children after replay (14 -> 14). The running JIN server itself +was not restarted; it must load the changed Python code on restart. + +## Transport lifecycle correction โ€” 2026-09-15 + +Explicit page departure now retires its runtime; unexplained disconnects have +a 600-second reconnect grace. A same-origin close beacon names both client id +and transport epoch, so a stale beacon cannot stop an anonymous reload/replacement +that reused the id. Retirement clears the scheduler's cached L-T context and +cancels guard/background work. Scheduler iterations release old local references +before waiting with an empty store. RuntimeStream propagates cancellation for +retiring transports instead of returning into the ordinary completed-turn tail. +USER-only interruption semantics remain. + +Verification includes shortened-clock expiry, real Edge reload during streaming +and action-guard waiting, tab close, reconnect replay, BFCache/freeze preservation, +same-origin/epoch rejection, and garbage collection of the retired context while +the global L-T scheduler remains alive. Model output is mocked in browser tests; +they do not use personal memory or call providers. + +## L-T backfill lost-update correction โ€” 2026-09-15 + +Backfill previously read/repaired a snapshot on the event loop, then persisted +it via `asyncio.to_thread`. That worker could overwrite a successful deletion, +value edit, or live mention committed by another runtime. Each of those losses +was reproduced before the fix in an isolated file-store regression test. + +Backfill now follows the other L-T writers: its latest-state read, repair and +write have no suspension point, and RAM publishes the repaired snapshot only +after persistence succeeds. Archive scanning stays off-thread. Six interleaving +tests cover changes during scanning and immediately after snapshot preparation, +including reload into a fresh context. This relies on the current single server +event loop; multiple processes sharing the profile would need separate locking. + + +## Disk bootstrap refactor โ€” 2026-09-26 + +D057 supersedes the older browser-authority notes above. Cognitive browser persistence is now page-local and startup selectors are resolved from disk. The latest saved FRAME retains full metadata; server snapshots/tool results are archived through existing JSONL writers. Session CLEAR uses a disk USER-count barrier. Existing unrelated dirty action-dispatch files were not changed by this refactor. + +During implementation, 85 targeted unittest cases, 20 targeted pytest cases and the migrated browser-storage unit test passed. Python compilation, JavaScript syntax and diff whitespace checks also passed before the final small cleanup. The Edge harness exercised poisoned storage, empty bootstrap requests and disk chat rendering, but its complete final run was stopped at the owner's request to skip further checks. No full-suite or final-browser green claim is made. Restart the backend and reload the page to activate the new protocol. + +## FRAME session titles and LOGS archive projection โ€” 2026-09-29 + +FRAME now owns one protected `session_title`, refreshed through the existing summarizer on every FRAME cycle, including hidden bootstrap. The LOGS tab lists USER-owned non-anonymous archives by date and reuses explicit archived restore in a new tab. Latest committed FRAME wins for list titles; legacy untitled sessions display their session ID, which is also the hover text for every title row. + +LOGS uses the common memory lazy-render pipeline with 20-row batches. The full index is fetched once per page, while successful disk commits publish `archived_session_update` so the current session can be inserted or retitled live; a per-session summary request reconciles a missed update without reloading the historical list. Session dialogue is fetched only while a row is hovered, shown in the existing memory hover-card as up to five newest USER-owned turns, and discarded on mouse leave. + +Short-click restores the session in a new tab. A 1500 ms hold reuses the shared fade/delete interaction and calls the disk DELETE endpoint. Only indexed USER-owned, non-anonymous archive directories are eligible; symlink escapes are rejected, an empty date directory is removed only when truly empty, and the live writer will not recreate a physically deleted session from a still-open runtime. diff --git a/docs/JIN_DECISIONS.md b/docs/JIN_DECISIONS.md new file mode 100644 index 00000000..9ca50492 --- /dev/null +++ b/docs/JIN_DECISIONS.md @@ -0,0 +1,807 @@ +# JIN Core Engine โ€” Durable Decisions + +**Decision baseline:** reconciled on 2026-10-01 against `jin_core(20261001-090403).zip`.

General runtime rules should describe only cross-action sequencing/invariants. + +**Why:** one model-facing source of truth prevents contradictory prompts and makes action evolution testable. + +**Rejected alternative:** duplicating the same action schema in `rules/runtime.py`, handlers, README, and prompt snippets. + +--- + +## D008 โ€” Delayed Memory save uses JSON under `` + +**Status:** Accepted / implemented with legacy parser compatibility + +Canonical form: + +```text + +{ + "title": "", + "summary": "", + "tags": [], + "body": "", + "anchor_lt_facts_ids": [], + "lt_facts_ids": [], + "attachments_ids": [] +} + +``` + +**Why:** explicit structured schema, safer validation, clearer ID relationships. + +**Rejected alternative:** advertising `` key/value body as current syntax. + +--- + +## D009 โ€” Active Memory model boundary uses explicit structured JSON + +**Status:** Accepted / implemented at the model boundary; internal storage remains transitional + +`SAVE_ACTIVE_MEMORY` is the single paired create/update block. Without `id`, its JSON root contains required `conditions` plus optional explicit custom fields and creates a record. With `id`, it updates that exact existing active-memory record and every other root field is a requested change; `conditions` may always change and custom fields must already exist. + +**Why:** one action owns the Active Memory write path while the presence of `id` makes create versus update explicit; update keys remain constrained to existing fields, and prose cannot be silently promoted into structure. + +**Strict format rule:** Active Memory updates accept only flat `SAVE_ACTIVE_MEMORY` JSON with exact `id: "AM-xxxxxx"`; old UPDATE markers/shapes, nested `fields`/`updates`, `active_memory_id`, and bare six-character IDs are rejected. SAVE custom fields come only from explicit JSON root fields; plain prose/parenthesized text remains conditions. + +--- + +## D010 โ€” Compatibility adapters stay local + +**Status:** Accepted / partially implemented + +When legacy data must still load, normalize it at a narrow boundary. Do not spread legacy conditionals through prompt assembly, UI, persistence, and action rules. + +**Why:** transition debt otherwise becomes permanent architecture. + +**Rejected alternative:** keeping multiple live formats everywhere โ€œjust in case.โ€ + +--- + +## D011 โ€” Current session continuity does not depend on a model `SAVE_SESSION` action + +**Status:** Accepted / implemented in current snapshot + +Live/session continuity is built around browser/runtime checkpoints, reconnect/bootstrap, archived chat/reasoning logs, and restore metadata. There is no current `SAVE_SESSION` contract. + +Historical `SAVE_SESSION` labels/fields can still be read for old archives/tests. + +**Why:** session continuity is runtime infrastructure and should not depend on the model remembering to emit a special save marker. + +**Rejected alternative:** reintroducing `SAVE_SESSION` from old docs/tests without a new product decision. + +--- + +## D012 โ€” Archived restore uses a staged one-shot priming path + +**Status:** Accepted / implemented + +Archived restore first gives Brain bounded exact historical context, then reactivates historical resources through the normal action pipeline. Resource state is not applied independently again at the WebSocket tail. + +**Why:** prevents duplicate apply/races and preserves a natural continuity greeting before old resources become normal live state. + +**Rejected alternative:** multiple independent restore writers that all โ€œensureโ€ final state. + +--- + +## D013 โ€” Interrupted turn is not a completed turn + +**Status:** Accepted / implemented + +Stop/cancel/repetition/context-limit interruption must preserve separate lifecycle semantics. A real USER move is retained in the latest-session/bootstrap tail even when no JIN row exists, but it must remain USER-only rather than being rewritten as a completed exchange. An action-only completed turn may also have no visible JIN text; its durable empty JIN row/timestamp is the completion marker. + +**Why:** bootstrap continuity must reflect what actually happened. + +--- + +## D014 โ€” Historical timestamps are data, not render-time defaults + +**Status:** Accepted / implementation must be protected + +Serialize/deserialize must preserve entity/snapshot timestamps. `now()` is only a fallback for a truly legacy record with no timestamp. + +**Why:** ordering, age, context relevance, and visible history become false if reload mutates time. + +**Rejected alternative:** stamping restored rows with current time for convenience. + +--- + +## D015 โ€” Anonymous mode is an explicit empty room, not browser-private detection + +**Status:** Accepted / implemented + +Long-pressing the avatar opens a fresh JIN room with a generated `_anon` session id. Active, Delayed, Facts Memory candidates, and L-T use the ordinary memory folders with `_anon.json` filenames, are shared by concurrently open anonymous rooms, and are deleted after the last anonymous room closes. The browser is only a projection of this anonymous file-backed profile; normal memory never seeds it. FRAME remains tab/runtime-local and does not create a crash journal for anonymous rooms. Global non-memory/asset writes remain restricted. Chat and reasoning remain auditable in ordinary `logs/` under the suffixed session id, while normal bootstrap and L-T freshness scanners ignore those logs. + +**Why:** anonymous experimentation must not inherit or contaminate the durable memory room, and browser Incognito detection is not a reliable product primitive. + +**Rejected alternative:** inferring browser private mode or maintaining a second `logs_anon` archive root. + +--- + +## D016 โ€” UI must reuse JIN's existing visual language + +**Status:** Accepted / mandatory + +Before adding a bubble, banner, highlight, tooltip, hover state, button, or feedback effect, find the closest existing JIN primitive and reuse it. + +**Why:** color/glow/geometry already encode runtime semantics. Random new visuals create false meanings and make the system look like mixed UI kits. + +**Explicitly rejected:** inventing a new blue/turquoise/green highlight just because a feature is new; generic SaaS success/error badges; cheerful icon sets; unnecessary blur. + +--- + +## D017 โ€” Loaded, referenced, inspected, pinned, paused, and deleted are distinct UI semantics + +**Status:** Accepted / implemented in parts, regression-sensitive + +Examples: + +- full object loaded into prompt -> strong/active context signal; +- ID merely cited/referenced -> weak linked signal; +- modal opened -> inspect only, not context load; +- pin/unpin -> persistence/loading preference; +- pause -> excluded from context without delete; +- delete/restore -> lifecycle mutation. + +**Why:** visual causality must match runtime causality. + +**Rejected alternative:** calling one generic highlight routine on every UI interaction. + +--- + +## D018 โ€” UI interaction language should converge, not proliferate + +**Status:** Accepted / partially implemented + +Memory/file items use a shared interaction language where applicable: long press for delete, half-long pause, click to restore/pending/open according to the existing component semantics. + +**Why:** fewer special-case controls and a more coherent object language. + +**Rejected alternative:** adding a separate conventional delete button to every item while the gesture contract already exists. + +--- + +## D019 โ€” JIN visual actions use ordinary source-order execution + +**Status:** Accepted / implemented + +Color/reaction/size/position/speed markers are normal runtime actions. The dispatcher fully prepares and runs each emitted call before touching the next one, so visual state changes in exact model source order. There is no visual-sequence collector, action-stage priority, or client sequence buffer. + +Only a true no-op repetition in the same runtime-message scope may be filtered where that action supports it. Alternation such as red -> blue -> red must remain ordered, and a later message may intentionally request the same value again. + +**Why:** visual actions should share the same predictable action semantics as the rest of the runtime while preserving the model's expressive order. + +**Rejected alternatives:** restoring the removed visual-sequence collector; adding a second parallel animation scheduler; using contract `runtime_order` or registry stages to reorder emitted calls. + +--- + + +## D020 โ€” Do not invent a second source of truth to fix restore/UI bugs + +**Status:** Accepted / mandatory + +For bootstrap, tint, timestamp, linked-highlight, and session bugs, first enumerate every writer and establish ordering. + +**Why:** many prior regressions were duplicate-apply problems. + +**Explicitly rejected:** second listeners, second tint writes, duplicate guards without identity analysis, render-time `Date.now()`, state-only hover payloads that never reach DOM. + +--- + +## D021 โ€” `RUNTIME_SETTINGS` is the first optional live-settings block + +**Status:** Accepted / implemented + +`rules/brain_context_builder.py` owns `CURRENT_RUNTIME_SETTINGS_CONTENT`. If it is empty, the `` block is omitted. On ordinary turns it precedes the remaining live prompt scaffolding; restore continuity keeps its documented preamble first. + +**Why:** this block is an explicit runtime-level override/context injector and must have deterministic placement. + +--- + +## D022 โ€” Keep heavy/background work off the foreground critical path where possible + +**Status:** Accepted / implemented in principle + +Optimization priority: + +1. delete redundant calls; +2. safely combine calls without changing ordering; +3. cache stable results; +4. move non-required work to idle/background; +5. keep only causally required operations on the foreground path. + +**Why:** chat latency is a product concern. + +**Constraint:** never trade ordering, memory correctness, recoverability, or observability for fewer calls. + +--- + +## D023 โ€” No large framework rewrite before v1.0 + +**Status:** Accepted + +The existing JIN skeleton already has state, named prompt sections, dynamic context, actions, continuity, pruning/tool-result handling, observability, and model roles. + +**Why:** a framework migration before v1.0 creates risk without proving a product gain. + +**Rejected alternative:** rewriting JIN around DeepSeek-style/other agent harnesses because their vocabulary looks similar. + +--- + +## D024 โ€” `FRAME` is the canonical product name for live runtime memory + +**Status:** Accepted / implemented + +The first memory-panel tab is labelled `FRAME`, Brain context exposes it as ``, and current documentation uses FRAME for the live runtime-memory concept everywhere. It retains snapshot/diff paging and remains distinct from Active, Delayed, L-T, Files, and durable checkpoints. + +Implementation modules, state fields, events, pending journals, UI identifiers, and tests use FRAME naming. The previous internal name has no compatibility reader or fallback path; old pending journals and wire events are intentionally unsupported. + +The memory panel exposes five memory views โ€” `FRAME`, `ACTIVE`, `DELAYED`, `L-T`, and `FILES` โ€” plus a sixth `LOGS` archive projection. `LOGS` is not a memory layer: it indexes restorable disk sessions. The temporary unprocessed-facts view is not part of this tab bar. The shared count/paging control sits below the active tab; arrows are visible only for `FRAME`. + +--- + +## D025 โ€” Header auto-hide behavior: delayed reveal, slower hide + +**Status:** Accepted / code currently differs on reveal delay + +Product intent recorded on 2026-08-21: + +- reveal only after hover dwell of roughly 250 ms; +- hide roughly 1 s after leaving; +- reveal catch zone must not fire merely because the pointer passes over the avatar/panels. + +Current code uses 333 ms reveal and 1000 ms hide. This mismatch is documented, not silently resolved here. + +--- + +## D026 โ€” Search actions require real configured provider capability + +**Status:** Accepted / implemented + +`WEB_SEARCH` and `DEEP_WEB_SEARCH` are model-visible only when both their runtime feature flags and `settings.CAN_SEARCH` allow them. For the current Serper integration, local capability means provider `serper` plus a non-empty, non-placeholder API key supplied through the process environment. Secrets do not belong in `config.py` or `config.example.py`; the Windows launcher may populate its child process from an ignored repository-root `.env`, with `.env.example` documenting names through placeholders only. + +**Why:** advertising an action that cannot execute creates fake affordance and failed loops. Conversely, Serper does not define a stable client-side key shape, so arbitrary length/prefix regexes can incorrectly hide valid credentials. + +**Rejected alternatives:** feature flags alone deciding search availability; hard-coding guessed Serper key formats instead of letting the provider validate credentials. + +--- + +## D027 โ€” `CLEAN_TOOL_RESULTS` is an authoritative field-local tombstone, not a checkpoint refresh + +**Status:** Cleanup semantics retained; browser-checkpoint persistence superseded by D057 + +Full cleanup is requested with an empty `` block. Targeted ` T1, T2, T3 ` persists only the survivors; IDs are comma-separated and validated as one atomic set before mutation. New results have increasing temporary `tool_id` values, also retained in action history; the counter survives cleanup/bootstrap. Legacy results remain ID-less and require full cleanup. Any invalid or missing target fails visibly without clearing any listed result. The resulting empty/survivor set is authoritative and must not be repopulated from older archived tool results. + +D057 moved reload authority from the former browser checkpoint to disk-owned checkpoint/tool-result events. Page-local browser projections may mirror the cleaned result set, but they do not choose reload state or freshness. + +This exact-empty rule is intentionally scoped to `tool_results`; other empty collections keep their own restore semantics. + +**Rejected alternatives:** treating browser state as reload authority after CLEAN; treating every empty collection as either universally authoritative or universally missing. + +--- + +## D028 โ€” Session-action interruption telemetry is emitted at cause time + +**Status:** Accepted / implemented + +Validator/reasoning loops and context/output-limit recovery must append and emit their session-action entry immediately when the interruption is detected, before automatic continuation/follow-up runs. `context_overflow` belongs to the context-limit recovery family. + +**Why:** Session Actions is causal runtime telemetry. If the event appears only after the final answer, the UI gives a false ordering of what the runtime was doing. + +**Rejected alternative:** recording the interruption only during end-of-turn/final response compaction. + +--- + +## D029 โ€” Structured Session Action metadata is continuity data + +**Status:** Accepted / implemented + +Bootstrap sanitization must preserve recognized structured action-part metadata required by the logger, not only human-readable text. For JIN_COLOR, `parts[].colors` round-trips through bootstrap and is normalized to lowercase `#rrggbb` so restored rows keep color swatches and hex hover text. + +**Why:** text-only restoration can look superficially correct while silently destroying UI semantics after reload. + +**Rejected alternative:** reducing persisted/restored action parts to `text/detail/message/id` when additional recognized metadata drives the existing projection. + +--- + +## D030 โ€” Surfaced L-T evidence expands; ordinary rows stay compact + +**Status:** Accepted / implemented + +The ordinary L-T panel uses a compact 50-character value preview. A fact bubbled by runtime reference, explicit reasoning citation, or context-loaded state displays the full value with no truncation. + +**Why:** the panel should remain scan-friendly by default, while evidence JIN actually surfaced must be readable in full. The expansion is a UI projection and must not mutate canonical L-T storage/order. + +**Rejected alternatives:** truncating surfaced citations; expanding every L-T row all the time. + +--- + +## D031 โ€” JIN color and size use paired XML at the model boundary + +**Status:** Accepted / implemented with localized legacy compatibility + +Canonical forms put payload in the body: + +```text + #00f2ff + w:120 h:120 +``` + +Inline/colon/space forms may still be recognized by compatibility parsing, but contracts and prompt instructions teach only the paired form. Removing a marker must preserve ordinary visible answer text on both sides and across arbitrary stream chunk boundaries. + +`JIN_SIZE` values preserve their declared unit across the model/parser/event boundary. Positive decimal `px`, `vw`, `vh`, and `%` values are supported; a missing unit means `px`. Relative units are resolved only in the live browser: `%` follows the corresponding width/height viewport axis, while `vw` and `vh` always follow viewport width and height. Persistence records the resulting rendered pixel geometry rather than the unresolved command. + +**Why:** a real closing boundary prevents an inline marker parser from swallowing the answer tail and gives streaming one deterministic completion point. + +**Rejected alternative:** advertising legacy `` / `` as the preferred syntax. + +--- + +## D032 โ€” The newest real USER move owns normal continuation + +**Status:** Accepted / implemented; source-selection wording updated by D057 + +Disk archive selection identifies the last runtime session that actually moved. Opening a blank/bootstrap-only tab does not create a stronger continuation owner. A real USER send can make its session the newest continuation candidate even when the turn is interrupted before a JIN row is written; `conversation_committed_at` remains a separate completed-turn timestamp. + +Browser/page-local projections do not participate in source selection. Within the disk archive, the newest real USER move wins, including USER-only interrupted turns. + +**Why:** continuity follows the conversation the user actually touched, not whichever tab most recently initialized or flushed presentation state. + +**Rejected alternatives:** newest runtime ID wins; newest presentation/checkpoint timestamp wins regardless of USER activity; dropping interrupted USER-only moves. + +--- + +## D033 โ€” Bootstrap freshness is resolved inside the disk-owned source + +**Status:** Browser-authority design superseded by D057; disk freshness semantics implemented + +Reload/new-tab bootstrap no longer arbitrates browser state against the archive. Disk-owned session material is the only reload authority: recent dialogue/reasoning comes from raw logs, FRAME comes from committed frame snapshots/context fallback, and session actions/tool results come from ordered server-emitted events/checkpoints. Empty disk values remain authoritative. + +A live WebSocket reconnect is a separate case and may reuse the in-process `RuntimeContext`; page-local browser projections do not become a competing freshness clock. + +**Why:** one reload owner removes browser/archive races while preserving field-appropriate ordering inside the archive. + +**Rejected alternative:** one global timestamp or browser-vs-disk newest-record contest deciding every bootstrap field. + +--- + +## D034 โ€” JIN color has one server/disk bootstrap reconciliation path + +**Status:** Accepted / implemented; browser-authority clauses superseded by D057 + +Accepted JIN_COLOR updates `RuntimeContext.jin_color`, emits the live visual event, records an ordered raw runtime event, and is folded into the server session snapshot/action trail. There is no separate latest-color storage key. + +On normal reload/bootstrap, disk-owned session state restores the color into `RuntimeContext`. The browser then receives one authoritative color through `session_actions_update` with `bootstrap_restore=true`; page-local room/checkpoint projections may mirror live state but never outrank disk or choose the reload source. + +The first bootstrap color uses the one 2-second avatar-and-scene transition. Later/live colors use 333 ms. Projection-only updates must not mutate disk/bootstrap freshness metadata. + +**Why:** this removes the pink/gray/red flash-and-revert class caused by multiple color owners and late writers while keeping a single reload authority. + +**Rejected alternatives:** `latestJinColor`, `colorOnly` durable browser checkpoints, a client source-scanning resolver, a second tint-shift helper, or a delayed color queue. + +--- + +## D035 โ€” Normal bootstrap shows a bounded inherited chat tail + +**Status:** Accepted / implemented + +Normal bootstrap renders the five newest real USER moves with JIN/reasoning where present, then places the current-session date divider and starts the live viewport there. USER-only turns remain visible without an empty JIN bubble. Explicit archived restore uses its own history renderer but projects the same bounded USER-owned tail, keeps later visible JIN-only continuation rows, and must not duplicate the normal-bootstrap tail. Its reasoning bubbles contain the reasoning body, not archive-file headers. + +The hidden bootstrap Brain prompt projects continuity before the synthetic instruction: inherited `` first, then carried `` when available, then `` with the fresh current session ID/time and `!!! USER DIDN'T SEND NEW MESSAGE! !!!`. Legacy `` wrappers are reader compatibility and normalize into ``; they are not the current model-facing block name. + +For explicit URL restore, the server archive owns dialogue, reasoning, FRAME, Session Actions, and archived visual/runtime state as one causal restore payload. The page may mirror restored room/avatar state into its local projection after application, but browser storage cannot replace individual archive fields or become a restore source. The inherited dialogue/reasoning continuity is the newest conversational authority during the one-shot priming turn; restored FRAME is background and may be one update behind the final visible turn. + +**Why:** the user can scroll slightly upward for immediate continuity while the current response begins from a clean, stable boundary. + +**Rejected alternatives:** starting with an empty chat; dumping the whole archive; auto-scrolling inherited history below the current-session boundary. + +--- + +## D036 โ€” Recent model dialogue is bounded by pairs, not character-cropped + +**Status:** Accepted / implemented + +`` contains the newest five recent USER/JIN pairs. Every selected message body is preserved in full after newline normalization, literal `\\n` serialization, whitespace trimming, and XML escaping. There is no per-message character cap. + +**Why:** pair-count bounding already limits history breadth; silently cutting the substance of one selected message breaks exact conversational continuity. + +**Rejected alternative:** restoring `RECENT_MESSAGE_MAX_CHARS` or an equivalent hidden per-message slice without an explicit prompt-budget decision and regression coverage. + +--- + +## D037 โ€” Ordinary turns retain the previous completed reasoning edges + +**Status:** Accepted / implemented + +An ordinary user turn includes previous successful reasoning in ``. The projection preserves the whole block through 2000 characters; for a larger block it keeps the first and last 25% and replaces only the middle with an explicit `CUTTED N chars` separator. + +Action/recovery follow-ups move current visible dialogue and carried reasoning evidence to the front before `` and do not duplicate those blocks in the base prompt. Archived restore priming uses the same continuity-first ordering before its mandatory synthetic instruction. + +**Why:** the opening and conclusion preserve the previous line of thought without spending the entire context window on its middle, while dedicated follow-up context avoids stale or duplicated reasoning. + +**Rejected alternatives:** exposing previous reasoning only during session-restore priming; dropping the block from ordinary turns; duplicating it inside action/recovery follow-ups; trimming only one edge. + +--- + +## D038 โ€” Memory Attention replaces metabolism + +**Status:** Accepted / implemented + +The metabolism subsystem is removed. The retained `runtime/memory_attention.py` module performs only prompt-local Active lexical/context relevance, Delayed inventory bubble matching, and a narrow 1โ€“3 fact L-T focus. + +Memory Attention is deterministic and stateless: it does not call SERVICE, change Brain temperature, generate hidden instructions, learn phrase associations, mutate memory while building context, persist significance, or drive avatar chemistry. + +**Why:** the useful behavior was retrieval/ranking. The causal homeostat duplicated model work, obscured sampling, and leaked event-wide significance through FRAME into durable L-T. + +**Rejected alternatives:** keeping observer-only chemistry; keeping significance as an independent durable score; preserving the metabolic UI without the backend. + +--- + +## D039 โ€” Browser runtime continuity has one atomic checkpoint + +**Status:** Superseded by D057 on 2026-09-26; retained only as migration history + +This decision records the former v2 browser-owned reload design. It is not current bootstrap authority: D057 clears/ignores durable browser cognitive state and resolves reload/new-tab continuity from disk. `jin.liveRuntimeMemory.v2` remains page-ephemeral transport/projection state, while the retired durable `jin.sessionCheckpoint.v2` value is removed during startup rather than trusted for recovery. + +The historical design atomically stored session lineage, save/commit times, runtime memory/update count, runtime snapshot, and session snapshot in the browser, including a cleared tombstone and legacy migration rules. Those browser ownership/migration clauses are intentionally obsolete. + +Explicit archived restore remains server/disk-owned, and soft reconnect may still reuse live in-process runtime state; neither behavior revives the old durable browser checkpoint as a source of truth. + +**Why retained:** it documents the migration path and explains compatibility cleanup code without presenting that code as the current continuity model. + +**Rejected current alternatives:** split durable browser state, newest-timestamp browser scans, or any automatic browser-to-disk cognitive migration. + +--- + +## D040 โ€” Brain is the only foreground model route + +**Status:** Accepted / implemented with localized legacy readers + +Foreground user work always follows: + +```text +user -> AgentRuntime -> BrainNode -> clients["brain"] +``` + +SERVICE is a logical background role only. `clients/registry.py` aliases `clients["service"]` to the Brain client by default; an explicitly configured `SERVICE_API_BASE` replaces only that background client with a dedicated runtime. Foreground routing does not depend on Service availability or configuration. + +`USE_SERVICE_AS_BRAIN` is not a current runtime option. It is accepted only as old-config migration input: the loader promotes the legacy Service endpoint/settings into canonical Brain settings, clears the dedicated Service URL, removes the flag, and exposes normalized Brain-first configuration to the rest of the process. Launcher detection exists only to preserve this migration during startup. + +Archived `service` message roles, `RUNTIME_MODE=SERVICE`, and old `[SERVICE]` model-output logger cards may remain as reader compatibility until real historical data no longer needs them. They must not be used to reintroduce foreground Service execution. + +**Why:** the visible model path needs one canonical owner. A one-model installation should be possible without role inversion, while a second machine/model can still accelerate background memory/research work. + +**Rejected alternatives:** switching visible replies to Service; keeping `USE_SERVICE_AS_BRAIN` as a live runtime branch; requiring a dedicated Service endpoint; treating archived Service labels as evidence of current topology. + +--- + +## D041 โ€” Memory inspector edits values, never identity + +**Status:** Accepted / implemented + +Direct memory editing is an explicit UI/runtime write, not a model action. Double-click opens the existing details tooltip as an editor. FRAME permits edits only on the newest snapshot value; Active permits the conditions/value while preserving ID, custom fields, status and metadata; L-T permits only the canonical fact value while preserving key, ID, category, provenance and mention metadata. Keys and IDs are never editable. + +Drafts remain page-local until the server acknowledges the checkmark. Requests carry `expected_value` so stale concurrent edits fail rather than overwrite newer state. Manual FRAME writes (value edits and row deletions) wait while the live FRAME writer is busy; Active edits do not inherit that lock because Active Memory is an independent canonical store and remains directly editable during Brain/FRAME work. Rollback returns to the last acknowledged value. Active and L-T successful edits surface `updated_at`; L-T writes persist before publication and mark explicit-edit protection. + +**Why:** the inspector should allow surgical correction without turning editing into a second schema/action system or rewriting memory identity. + +**Rejected alternatives:** editable keys/IDs; editing historical FRAME snapshots; optimistic overwrite without expected-value conflict detection; routing manual edits through Brain. + +--- + +## D042 โ€” L-T recall decays by last real mention + +**Status:** Accepted / implemented + +Canonical L-T facts retain `mention_count` and `last_mentioned_at`. A valid `F` reference in JIN reasoning or visible output increments a canonical fact at most once per turn and persists the new mention timestamp. Historical-log backfill may repair older mention dates but must never rewind a newer live mention. + +For Brain context, a fact remains fully expanded until 24 hours have elapsed since its latest mention/update/create fallback. After that boundary, each sentence is previewed at a maximum of 100 characters. A later JIN reference refreshes the mention timestamp so subsequent prompts can receive the full value again. + +**Why:** old facts remain available without permanently spending full-context cost, while actually reused facts regain detail automatically. + +**Rejected alternatives:** deleting old facts for context pressure; decaying canonical stored values; using render-time age without persisted mentions; model-generated importance scores. + +--- + +## D043 โ€” L-T active/all is a projection, not a second store + +**Status:** Accepted / implemented + +Facts absorbed by Delayed reports are hidden from the default active L-T view unless they are currently context-loaded. Anchor facts remain visible. Clicking the L-T count toggles `show all` / `show active`; the all view uses the same normal fact sorting and does not append archived rows as a separate block. Report-linked fact IDs remain clickable and open the existing Delayed report modal. + +**Why:** report absorption should reduce panel/context noise without making facts disappear or creating a parallel archive store. + +**Rejected alternatives:** physically moving absorbed facts to another store; appending hidden facts unsorted; losing report navigation when hidden facts are revealed. + +--- + +## D044 โ€” Composer attachment chips represent context attachment, not file ownership + +**Status:** Accepted / implemented + +Pinned persistent files attached to the outgoing message are projected as compact chips next to the composer. Click reuses the existing preview. Hold detaches/unpins the file from outgoing context. Detach does not delete the persistent file, and attachment changes do not open Console as a side effect. + +**Why:** attachment state is temporary message/runtime context; persistent file ownership is a separate system. + +**Rejected alternatives:** deleting the asset on detach; a second preview UI; automatic Console expansion merely because a file was attached. + +--- + +## D045 โ€” Failed runtime actions reuse the contract schema and remain incomplete + +**Status:** Accepted / implemented + +Each concrete runtime-action contract owns a separate human-readable `schema` list in addition to its rules. The same schema is used in model-facing instructions and in failed tool results. A failure is rendered as readable text with status/reason, supplied payload when relevant, and `Correct action schema:`; the shared failure follow-up explicitly tells Brain not to treat the action as completed. + +**Why:** recovery should teach the model from the exact contract that rejected the payload instead of exposing raw JSON or duplicating schema text in error handlers. + +**Rejected alternatives:** raw JSON failure blobs; independent error-only schemas; continuing the turn as though a failed state mutation succeeded. + +--- + +## D046 โ€” Response copy is an explicit control, not an invisible bubble gesture + +**Status:** Accepted / implemented + +Completed assistant output exposes `Copy all` under the avatar/message host. The previous invisible bubble utility gesture surface is removed. Answer-rating implementation may remain release-disabled in the codebase, but it does not own release interaction. + +**Why:** copying should be discoverable and deterministic, and should not compete with text selection, inspection, or other long-press/double-click semantics. + +**Rejected alternatives:** hidden double-click copy; long-hold replacement retry on the answer bubble; re-enabling rating merely to host utility gestures. + +--- + +## D047 โ€” Live Avatar L-T capacity expands by lanes without changing memory identity + +**Status:** Accepted / implemented + +L-T facts are projected to Live Avatar in lanes of at most 100 records. Additional facts create additional outer L-T rings; Active Memory is laid out beyond the outermost L-T lane and before the persistent-file ring. Memory-row hover reuses the existing avatar zoom/reference semantics. + +**Why:** large durable stores must remain inspectable without overloading one ring or changing the underlying fact store. + +**Rejected alternatives:** hiding facts solely because the first ring is full; creating a second L-T store per ring; overlapping Active/File rings; inventing a new hover highlight family for overflow lanes. + +--- + +## D048 โ€” Chat recall starts with literal archive search + +**Status:** Accepted / implemented + +Whole-file recall uses `ATTACH_FILE_BY_ID` with an existing persistent system ID (text or image). Paths and source line ranges belong to `ATTACH_FILE_CONTENT`. Unknown IDs must fail, never become project paths. Success is displayed as `ATTACH_FILE_BY_ID: full_filename.ext`; a missing file is displayed as `ATTACH_FILE_BY_ID: id : failed - file not exists`. + +`CHAT_LOG_SEARCH` searches saved USER/JIN messages with literal case-insensitive substrings, OR queries, inclusive date/daily-time bounds and newest-first results. The default limit is 10 turns, hard maximum 50. Including JIN permits bounded reasoning excerpts only alongside a matching USER in that same turn; USER-only search excludes reasoning. Matched messages retain their attachment metadata. The full request and historical identities accompany results. Contract, errors, follow-up, bubbles and persistence reuse the existing runtime-action path. + +**Rejected alternatives:** embedding/index infrastructure for this first version; reasoning-only evidence without a matching USER; restoring historical resources as a side effect of search. See [CHAT_LOG_SEARCH.md](CHAT_LOG_SEARCH.md). + +--- + +## D055 โ€” Paired list actions and delayed-memory ownership + +**Status:** Accepted / implemented + +`WEB_SEARCH` uses ` query `. Delayed report loading, Active Memory deletion, and whole-file attachment accept comma-separated IDs in paired markers. Each ID becomes one ordered internal action. Model-issued `LOAD_DELAYED_MEMORY` results are ordinary tool results with tool IDs and can be removed through `CLEAN_TOOL_RESULTS`; they never populate ``. That block is exclusively owned by explicit user pin state. Consequently there is no model-facing `UNLOAD_DELAYED_MEMORY` contract. + +--- + +## D056 โ€” MCP integrations use one generic loaded-skill action + +**Status:** Accepted / implemented + +An MCP integration is a normal skill with one canonical `...` declaration. Loading the skill discovers the live server/tool catalog and appends it only to the in-memory skill context as ``. Core runtime exposes one generic `CALL_MCP` action rather than generating a Python action per external tool. `CALL_MCP` is model-visible only while a valid MCP skill is loaded. + +Each loaded MCP skill owns one persistent connection across automatic follow-ups; unload/runtime retirement closes it and a changed server config creates a new one. MCP calls are excluded from generic result reuse because external tools may mutate state. Returned MCP images join the ordinary pinned-file/attachment path so the next Brain follow-up can inspect them. + +**Why:** tool servers can extend JIN without expanding the core action registry per tool, while skill text retains semantic guidance and the server remains authoritative for live technical schemas. + +**Rejected alternatives:** one core runtime action per MCP tool; reconnecting a stateful stdio server for every follow-up; duplicating static MCP server identity/instructions in every tool result; keeping screenshot base64 in model context. + +--- + + +## Background-tab continuity โ€” 2026-09-08 + +An accidental socket disconnect is not a user Stop. Accepted foreground work, +FRAME integration and queued USER batches continue in the same server runtime. +Physical connections only deliver input/output. Unacknowledged output is replayed +on soft reconnect with page-local event deduplication; live server state wins +over the stale page snapshot. Browser freeze/discard cannot be prevented by a +server timeout setting. Process termination remains outside in-memory recovery. + +Owner clarification (2026-09-15): reload/close explicitly retires the departing +page runtime. If its departure signal is lost, retain a disconnected runtime for +10 minutes, then cancel its work and release it. Reconnecting within that window +preserves the live runtime. Connected background tabs and persisted BFCache pages +are not explicit departures. This bounds the earlier disconnected-retention rule; +it is not a ten-minute generation limit or a timeout on a connected action guard. + +--- + +## Malformed-action recovery โ€” 2026-09-10 + +**Status:** Accepted / implemented; repair-loop semantics reconciled 2026-09-24 + +Recognize the three owner-provided malformed envelopes without repairing or executing their payload. Every occurrence gets an independent `MALFORMED_ACTION` bubble, history item and T-id. The next shared follow-up starts with one ordered notification per occurrence: target action, original extracted payload, and the correct contract `schema`. Do not quote the malformed envelope in that notice. Valid action results and normal sequence history remain available together. + +The current loop grants one malformed repair tick outside the ordinary workflow follow-up budget. If that repair response is malformed again, stop the repair loop and run one final non-executable Brain response tick with runtime actions disabled. This supersedes the earlier "repeat repair indefinitely" wording. + +**Rejected:** a separate repair-only conversation, inferred action execution, collapsing repeated malformed attempts into one bubble, or an unbounded malformed-repair loop. + + + +## D049 โ€” Bootstrap lifecycle is fixed by the owner (2026-09-11) + +**Status:** Accepted. Do not redesign this flow during bootstrap/UI fixes. + +1. Console starts, a tab opens, JIN writes its startup greeting, USER never + responds and closes the tab: this session is NOT saved for continuation. +2. Console starts, a tab opens, JIN writes its greeting, USER sends a message + and closes the tab: this session IS saved; the next bootstrap sees that USER. +3. Console starts, a tab opens, USER presses Stop before the greeting, then + sends a real message and presses Stop: this session IS saved as USER-only. +4. Console starts, a tab opens, USER stops the greeting, sends a real message, + JIN answers: this session IS saved with that USER and its JIN/reasoning. + +A startup greeting, runtime ID, FRAME update, or completed bootstrap tick is +not a real USER send and cannot promote the session into durable continuation. +Stop cancels the pending/running startup tick; it must not resume later after a +FRAME wait or consume the subsequent real message. A real USER supersedes any +unfinished startup tick. Real USER input must survive interruption. + +Restore source sessions in chronological groups: USER then its actual answer +and reasoning, followed by one divider dated to that session's last message. +Earlier sessions remain above the newest session; never split a USER/JIN pair +with a divider or turn one send into two USER rows. Do not guess pair ownership +from identical text. Legacy archive corrections require concrete evidence and +must be isolated from the ordinary bootstrap algorithm. + +The owner's supplied MHTML for session 7e91148a-2077-454d-a3ec-be6028cd6aec +shows the final USER followed by the calmer-color answer/reasoning. Its JSONL +instead recorded that answer as turn 138 before USER turn 139, then an empty +JIN 139. The 2026-09-11 generic JIN-only-row rendering workaround was rejected; +it exposed the corrupt ordering rather than restoring the actual pair. + +Physical deletion is also authoritative (owner clarification, 2026-09-11): two +real photo messages survived provider crashes as USER-only turns, then the +owner deleted their date directory and restarted server/browser. localStorage +must not bring those deleted turns back. A missing source archive invalidates +the entire browser bootstrap replica; select the latest surviving real USER +archive even if older, or start empty when none survives. Reader exceptions +are not proof of deletion. Explicit archived checkout and anonymous isolation +retain their separate paths. + +Startup greeting/reasoning/actions remain in RAM until the first real USER +send flushes them with the original order and reasoning reference. Closing a +greeting-only tab must not create a date directory. Workers whose materialized +archive directory was removed must not recreate that directory with late writes. + + +## D050 โ€” Context overflow requests immediate tool-result cleanup (2026-09-18) + +**Status:** Owner requested / implemented + +Context overflow uses a separate `FOLLOW_UP_CONTEXT_OVERFLOW_MESSAGE`, asking Brain to skip deep reasoning and immediately emit `CLEAN_TOOL_RESULTS` with a redundant tool-result ID. Do not prepend the ordinary follow-up message or its last-executed-action/result suffix. Output-only limits keep their existing continuation. Preserve the current request sequence and record/emit the interruption before recovery, as a separate Session Actions row. Provider overflow errors and native completion at the provider-reported context boundary must not silently bypass this flow. + + +## D057 โ€” Disk is the only reload/bootstrap authority (2026-09-26) + +**Status:** Owner-approved / implemented. Supersedes browser-authority and browser migration clauses of D020, D027, D033, D034 and D039; preserves D049 lifecycle and explicit archive restore. + +A clean installation/folder must not inherit dialogue, FRAME, facts, actions or tool results from the same browser origin. Logs and existing memory files own recovery. Browser storage is only an operational projection; startup sends no cognitive payload. A live reconnect uses server RAM, and a restarted backend resolves disk again. Explicit checkout is a disk archive selector, not an uploaded snapshot. + +Use the latest saved FRAME with its original metadata, raw dialogue/reasoning/actions and server-emitted checkpoint/tool-result events. Empty disk values remain authoritative. Remove automatic browser Facts migration. Read errors never fall back to browser data. + +Session CLEAR keeps its semantics with an atomic disk USER-count barrier (`logs/.continuation-cleared.json`), not a localStorage tombstone. New USER activity can pass the barrier; passive completion cannot. Archives remain available for explicit restore. + +**Rejected:** merely adding a folder ID to localStorage, timestamp-based browser/disk arbitration, restoring browser state after a reader error, or trusting a browser-supplied archived payload. + +## D058 โ€” Session titles belong to FRAME and LOGS is an archive projection (2026-09-29) + +**Status:** Owner-approved / implemented. + +`session_title` is one reserved FRAME field, emitted on every full FRAME replacement and protected against omission, duplication, and manual deletion. The ordinary FRAME lifecycle is unchanged: a hidden bootstrap response may run FRAME and update the title. Titles have no separate store and require no extra model request. + +The memory panel's LOGS tab indexes restorable, USER-owned non-anonymous archives. It uses the latest committed `frames/` snapshot when present, otherwise the matching primary context snapshot, and shows the session ID for legacy archives without a title. The complete HTTP index is fetched once per page; live `archived_session_update` events insert/retitle the current row, and a focused per-session summary request repairs missed events without reloading the full archive list. Hover preview shows the newest USER-owned turns, including unanswered/action-only USER turns. + +Short click opens the existing `restore_session` flow in a new tab. A 1500 ms hold uses the same fade/hold interaction as the other memory rows and deletes the indexed archive through the server endpoint. Deletion rejects anonymous, unsafe, non-indexed, or symlinked targets, removes an empty date directory, and a still-live writer must not recreate a materialized archive the user deleted. Current global durable memory remains governed by the existing restore contract. diff --git a/docs/MCP_SKILLS.md b/docs/MCP_SKILLS.md new file mode 100644 index 00000000..0371c81a --- /dev/null +++ b/docs/MCP_SKILLS.md @@ -0,0 +1,99 @@ +# MCP Skills + +JIN exposes MCP through one generic runtime action: `CALL_MCP`.
