Schema version is always `"context.v2"`. (2) New `scale` package provides `EstimateTaskScale(title, description)` with combined word-count thresholds (small < 100, medium < 300, large ≥ 300) and keyword overrides (`refactor`/`migrate`/`redesign`/`overhaul`/`architecture` → large regardless of count). The scale package imports `wire` and is not imported by `wire` — leaf constraint preserved. (3) Migration 032 adds `planning_context_snapshots` table with FK cascade on `planning_run_id`. Migration 033 adds `context_pack_id TEXT NOT NULL DEFAULT ''` to `planning_runs`. Both use `TEXT NOT NULL DEFAULT ''` for JSON columns (SQLite-compatible). (4) `CreateWithBinding` generates a second `uuid.New()` for `packID` and persists it as `context_pack_id` on INSERT. All SELECT column lists and `scanPlanningRun` are updated to include the new column. (5) `ContextSnapshotStore` (new file) provides `Save` + `GetByRunID`; not wired to any handler yet (PR-2 concern). (6) `main.go` instantiates `contextSnapshotStore` with a `_ =` blank-assignment so the compiler does not error until a handler consumes it in PR-2. +- **Constraints introduced**: (a) `wire` remains a leaf — no imports outside stdlib + `time`. (b) `scale.EstimateTaskScale` word count is computed on the combined lowercased `title + " " + description` string; callers must not pre-process the text. (c) Migration 032 `.down.sql` drops the table and index cleanly on both SQLite and Postgres; migration 033 `.down.sql` is a `SELECT 1` no-op (SQLite has no DROP COLUMN — consistent with the existing 033-family pattern). (d) `context_pack_id` on old rows is empty string (DEFAULT '') — callers must treat empty as "no snapshot yet". (e) The DECISIONS.md 2026-04-25 entry reserved migration 032 as a "PR-3 placeholder" (LLM router); that reservation is superseded by this PR which physically creates 032.

-- **Constraints introduced**: `showDriftPreview` and `showRequirementIntake` are local state in `ProjectDetail.tsx`; no state was lifted to parent/child components. `SyncStatusPanel` initializes `expanded` via a `useState` initializer function (runs once on mount, not reactively). If the conditions that would auto-expand change after mount (e.g., sync fails while the panel is already collapsed), the panel does not auto-re-expand — the user must click Details. This is intentional; re-expansion on state change would be disruptive.

 ## 2026-04-22: Provider.Generate takes context.Context; OpenAI egress consumes wire.PlanningContextV1; SSE deferred; UI split deferred [agent:backend-architect]
 
 - **Context**: Pre-v1 hardening pass identified three Tier 3 follow-ups from the 2026-04-21 decision: (T3.A) `Provider.Generate` had no `context.Context`, so request cancellation, deadlines, and tracing could not propagate from the HTTP handler into the LLM call; the OpenAI provider built its own `context.Background()`, which leaked the request lifetime. (T3.B) Even with the 2026-04-21 sanitizer fixes, the server-side prompt builder still consumed the internal `PlanningContext` directly and reapplied a subset of `wire` helpers ad hoc; the connector path and the server path therefore had two slightly different egress contracts. (T3.C) `frontend/src/pages/ProjectDetail.tsx` is a single 3206-line function with no component or hook extraction and no UI tests, making any "split" risky to land in the same PR as backend correctness fixes. (T3.D) Real-time UI updates use 20s polling + `visibilitychange` + the `anpm:refresh-notifications` window event; SSE/WebSocket support remains unimplemented.

-## 2026-04-21: Server-side LLM provider must apply wire sanitizer + request body cap
-
-- **Context**: `OpenAICompatibleProvider` built its outbound prompt directly from the internal `PlanningContext` via `compactX` helpers. `AgentRun.Summary` and `SyncRun.ErrorMessage` were truncated only by char count; `wire.RedactSecrets` (used on the local-connector path) was not applied. There was also no upper bound on the marshalled request body, so a pathological project with very large summaries could egress unbounded bytes to the configured remote endpoint. The local connector path (`BuildContextV1` → wire sanitizer → `ReduceSources` 256 KiB cap) was strictly safer than the server path that called the same model — an asymmetry that violated the "context.v1 is the single sanitization contract" intent of the 2026-04-20 sanitizer decision.
-- **Decision**: (a) Export `wire.RedactSecrets` and `wire.TruncateRunes` so non-wire callers can apply the same v1 redaction without owning the regex set. (b) `OpenAICompatibleProvider.compactSyncRunForPrompt` and `compactAgentRunsForPrompt` now redact and truncate using those helpers (caps `wire.MaxSyncRunErrorChars` / `wire.MaxAgentRunSummaryChars`). (c) `OpenAICompatibleProvider.Generate` enforces `defaultOpenAICompatibleMaxRequestBytes = 256 KiB` on the marshalled request body and returns a typed error instead of egressing the over-cap payload. The cap mirrors `wire.DefaultMaxSourcesBytes` so server- and connector-path egress budgets stay aligned. (d) `ProjectContextBuilder.Build` no longer silently swallows store errors for documents/drift/sync/agent-runs; it logs and accumulates a per-source warning string. `BuildContextV1` propagates those warnings into `wire.PlanningContextMeta.Warnings`, giving adapters a deterministic degraded-mode signal. (e) Router CORS replaced the `AllowedOrigins:["*"] + AllowCredentials:true` combination (which browsers reject) with an env-driven allowlist (`CORS_ALLOWED_ORIGINS`) and safe localhost defaults; a literal `*` allowlist now disables credentialed CORS instead of silently breaking auth.
-- **Alternatives considered**: (1) Promote `wire.PlanningContextV1` as the only input to providers (full Tier-2 refactor that would also let `Provider.Generate` accept `context.Context`) — deferred. The interface change rippled through 4 implementations and 5 tests for marginal additional safety on top of (a)–(c); it is recorded as the next step rather than blocking these fixes. (2) Leave silent error swallowing in the context builder and rely on logs alone — rejected; adapters need a structured signal to mark a recommendation as evidence-degraded.
-- **Constraints introduced**: All new server-side LLM providers MUST sanitize free-form fields with `wire.RedactSecrets` before egress and MUST enforce a request body cap no larger than `wire.DefaultMaxSourcesBytes`. `wire.PlanningContextMeta.Warnings` is now part of the wire contract — adapters MUST tolerate the field but MAY ignore it. Production deployments MUST set `CORS_ALLOWED_ORIGINS` to the canonical UI host(s); leaving it unset preserves localhost-only behavior, which is unsafe for any non-development deployment. Reference adapters (`adapters/*.py`) are now committed with executable permission bits to avoid the exit-126 failure mode that surfaced when the connector serve loop tried to spawn them on a fresh checkout.

-## 2026-04-20: Local connector planning runs emit in-app notifications; FE auto-refreshes the badge
-
-- **Context**: The notification model, store, REST endpoints, and bell-badge UI were fully implemented, but no caller in the planning flow ever invoked `NotificationStore.Create`, and `App.tsx` only fetched the unread count once at bootstrap. End users running planning via a paired local connector therefore had no signal that a run finished unless they were already on the project page.
-- **Decision**: When a local-connector planning run reaches a terminal state inside `LocalConnectorHandler.SubmitPlanningRunResult`, emit a best-effort notification scoped to the run's `requested_by_user_id` (falling back to the connector owner). Success uses `kind=info` with the candidate count and a deep link to `/projects/{project_id}`; failure uses `kind=error` with a truncated error message. Notification delivery never blocks run finalization — failures are logged and swallowed. On the frontend, `App.tsx` polls `getUnreadCount` every 20 s while the user is signed in, refreshes immediately on `visibilitychange`, and exposes a `anpm:refresh-notifications` window event that `ProjectDetail.tsx` dispatches the moment a watched run flips from active to terminal. The same transition surfaces a one-shot success/failure flash banner on the run card.
-- **Alternatives considered**: (a) Server-Sent Events / WebSockets for push-based notifications — deferred; polling is sufficient for MVP and avoids a new transport layer. (b) Emit notifications inside `PlanningRunStore.CompleteLocalConnectorRun` to also cover server-provider runs uniformly — rejected for now; coupling persistence to side effects fights the layering and the server-provider path can be revisited when a parity gap actually shows up.
-- **Constraints introduced**: Notification kind must remain in the `info | warning | error | drift | agent` enum; the helper currently uses `info`/`error`. The frontend custom event name `anpm:refresh-notifications` is a stable contract — any other page that wants to bump the unread badge must dispatch the same event.

-## 2026-04-20: Local connector is user-scoped, serves all of a user's projects
-
-- **Context**: Users asked whether a paired connector handles one project or many, and how to run concurrent planning runs across projects. The claim endpoint also previously dropped `planning_context` on its way into the adapter (a service-layer regression in `RunOnce`).
-- **Decision**: A paired local connector is scoped to the owning user, not to a project. `LeaseNextLocalConnectorRun` already selects the oldest queued run across the user's entire account; this is affirmed as intentional. The `claim-next-run` response now also carries the owning `Project` (id, name, description) so adapters and connector logs can identify which project the current run belongs to. `Service.RunOnce` forwards both `Project` and `PlanningContext` into `ExecJSONInput`, fixing a latent bug that dropped the planning context.
-- **Alternatives considered**: (a) Introduce per-connector project allowlists — rejected for MVP; adds schema + UX surface with no concrete use case yet. (b) Make the connector multiplex parallel runs — rejected; single-threaded FIFO keeps resource usage predictable on a developer laptop. Parallelism is achieved by pairing additional devices.
-- **Constraints introduced**: Concurrent planning across projects on a single device is serialized (FIFO). Operators who need real parallelism must pair multiple devices, each running its own `bin/anpm-connector serve`. Docker-compose is supported for the server but the connector intentionally runs on the host where the agent CLI is authenticated (e.g. where `claude login` has stored credentials).
-
-## 2026-04-20: Ship reference `adapters/backlog_adapter.py` for local connector
-
-- **Context**: The local connector speaks the `exec-json` contract, but operators had nothing concrete to plug into `--adapter-command`. Users cannot evaluate the end-to-end loop without building their own adapter.
-- **Decision**: Ship `adapters/backlog_adapter.py` — a Python 3 reference adapter that reads the `exec-json` request (including `planning_context`), shells out to the Claude Code CLI (default) or Codex CLI (`ANPM_ADAPTER_AGENT=codex`), and parses ranked backlog candidates from a fenced JSON code block. User-supplied adapters remain fully supported as long as they honor the same stdin/stdout contract.
-- **Alternatives considered**: (a) Ship a Go-based adapter binary — rejected; Python keeps the reference implementation easy to fork and read, and the contract is language-agnostic. (b) Build an HTTP-based adapter calling OpenAI-compatible endpoints — rejected for v1 because Claude/Codex CLIs already own auth + model selection on the operator's machine, avoiding a second credential surface.
-- **Constraints introduced**: Adapter output is normalized before reaching the server: `priority_score`/`confidence` clamped to `[0,1]`, title truncated to 120 chars, evidence ids coerced to strings, errors surfaced via `error_message` with exit code 0. Frontend `ProjectDetail.tsx` auto-polls every 3 s while a planning run is `queued`/`leased`/`running` so connector results surface without manual reload.

-## 2026-04-20: Adopt `context.v1` as local connector planning context contract
-
-- **Context**: Local connector adapters (`exec-json`) currently receive only `{run, requirement}` and cannot produce high-quality backlog candidates grounded in project state. The MVP core capability "agent auto-decomposes requirements into backlog" requires structured project context.
-- **Decision**: Introduce a versioned `planning_context` payload (`schema_version: "context.v1"`) attached to `POST /api/connector/claim-next-run` responses and forwarded through adapter stdin. Source of truth: `docs/local-connector-context.md`.
-- **Alternatives considered**: (a) Re-use `PlanningContext` directly as the wire type — rejected because it would pull server-only planning code into the connector binary. (b) Let adapters query server APIs for context — rejected because adapters are external processes without session tokens.
-- **Constraints introduced**: Wire DTOs must live in a leaf package (`backend/internal/planning/wire`) that imports only `models`; `planning` and `connector` both import `wire`, never each other. Adapters MUST ignore unknown fields and MUST treat missing `planning_context` as degraded-but-OK mode.
-
-## 2026-04-20: Metadata-only documents in local connector context
-
-- **Context**: Document bodies can be large, may contain sensitive content, and are not consistently useful to backlog decomposition.
-- **Decision**: Phase A of `context.v1` sends documents as metadata only (title, file_path, doc_type, is_stale, staleness_days) — matching existing `compactDocumentsForPrompt` in `openai_compatible_provider.go`. Body transmission is deferred to a future opt-in design.
-- **Alternatives considered**: Send full bodies with size cap — rejected; cap alone does not address sensitivity and regresses relative to current server-side provider behavior.
-- **Constraints introduced**: Adapter-generated backlog candidates must rely on title + path + staleness to cite documents as evidence. File-path-based reading is the adapter's own responsibility if it has filesystem access.
-
-## 2026-04-20: Context sanitizer v1 scope and excluded bare hex regex
-
-- **Context**: Free-form strings in `AgentRun.Summary` and `SyncRun.ErrorMessage` occasionally contain secret-shaped substrings (API keys, bearer tokens, basic-auth URLs). Earlier plan draft included a bare `\b[A-Fa-f0-9]{32,}\b` regex that would destroy 40-char git commit SHAs and legitimate hashes in diagnostic text.
-- **Decision**: Phase A sanitizer scope limited to `AgentRun.Summary` and `SyncRun.ErrorMessage`. Regex set is prefix-anchored: OpenAI `sk-…`, AWS `AKIA…`, PEM headers, `bearer ` (≥16 chars), basic-auth URLs, labeled secrets (`password=`, `token:`, `api_key=`), `sha256:` labeled hashes, `Authorization:` header dumps. Bare hex regex is explicitly excluded. Sanitizer version constant: `"v1"`.
-- **Alternatives considered**: Aggressive entropy-based redaction — rejected for false-positive rate. No sanitizer — rejected because `AgentRun.Summary` is agent-generated and known to occasionally leak auth errors verbatim.
-- **Constraints introduced**: Any change to the regex set requires a sanitizer version bump and a new DECISIONS.md entry.
-
-## 2026-04-20: Connector context byte cap applies to `sources` only
-
-- **Context**: `planning_context` has scaffolding (schema_version, limits, meta) plus `sources`. Applying a single cap to the whole payload creates pathological cases where scaffolding overhead alone exceeds the cap.
-- **Decision**: `max_sources_bytes` (256 KiB default) applies only to the marshaled `sources` object. Scaffolding and envelope are excluded from the cap. `meta.sources_bytes` records the final size. Reducer drops lowest-rank items from the largest-in-bytes source, re-measured each round.
-- **Alternatives considered**: Cap on full payload — rejected per above. No cap — rejected because a runaway project with thousands of drift signals could produce multi-megabyte payloads and break adapter stdin.
-- **Constraints introduced**: Adapters must be prepared to receive `dropped_counts` > 0 and cannot rely on "all open drift signals" being present.
-
-## 2026-04-14: Use SQLite as Phase 1 data store
-
-- **Context**: Need a lightweight database that avoids extra containers and keeps RAM usage low.
-- **Decision**: Use SQLite for Phase 1-3. Migrate to PostgreSQL in Phase 4 if concurrent write throughput becomes a bottleneck.
-- **Alternatives considered**: PostgreSQL from day one — rejected because it adds a container and ~200MB RAM for a system that initially serves a single user or small team.
-- **Constraints introduced**: All SQL must be compatible with SQLite. Use `database/sql` with a driver that supports both SQLite and PostgreSQL to ease future migration.
-
-## 2026-04-14: Move backend runtime to PostgreSQL now
-
-- **Context**: The project already reached Phase 4 capabilities (sessions, RBAC, full-text search, agent lifecycle) and now needs production-aligned behavior for concurrent access and reliable full-text querying.
-- **Decision**: Use PostgreSQL as the backend runtime database now, including local Docker Compose development. Migrations and runtime SQL use PostgreSQL semantics (`$N` placeholders, `BOOLEAN`, `TIMESTAMPTZ`, Postgres full-text search).
-- **Alternatives considered**: Keep SQLite through additional phases — rejected because it complicates correctness for search and boolean handling while increasing migration risk later.
-- **Supersedes**: This decision supersedes the earlier "Use SQLite as Phase 1 data store" decision for active runtime defaults.
-- **Constraints introduced**: Docker runtime requires a PostgreSQL service and `DATABASE_URL`. Data reset/re-seeding is required when moving existing local SQLite state.
-
-## 2026-04-14: Scrum-first backlog-before-implementation workflow
-
-- **Context**: Implementation often started before clear backlog capture and prioritization, causing requirement backfill after coding.
-- **Decision**: Enforce a Scrum-first execution order: discover, triage, check decisions, capture backlog, prioritize backlog, then implement.
-- **Alternatives considered**: Implementation-first with post-hoc planning — rejected due to rework and unclear priorities.
-- **Constraints introduced**: Tasks are not considered implementation-ready until backlog items and acceptance criteria are explicitly recorded.

-## 2026-04-17: Apply approved planning output at candidate scope
+## 2026-04-25: Phase 6b — role-dispatch task execution loop closed
 
-- **Context**: Phase 2 planning review persists multiple backlog candidates per requirement and per planning run. A requirement-scoped apply contract would mix one-to-many planning state with a bulk side effect before the aggregate rules are settled.
-- **Decision**: Apply approved planning output with `POST /api/backlog-candidates/:id/apply`. The operation creates at most one task, writes one `task_lineage` record, marks that candidate `applied`, and is idempotent for retries of the same candidate.
-- **Alternatives considered**: `POST /api/requirements/:id/apply` bulk apply — rejected because it couples candidate review state to requirement-wide mutation too early. Auto-promote requirement status to `planned` on first apply — rejected because a requirement may have multiple candidates or multiple planning runs and the aggregate rule is not yet defined.
-- **Constraints introduced**: Only `approved` candidates may be applied. Duplicate open tasks are blocked by normalized-title conflict detection within the project. Requirement status remains unchanged during candidate apply until a separate aggregate rule is introduced.
+- **Context**: Phase 5 established `execution_role` on `backlog_candidates` as a hint for which prompt role a connector should run. Phase 6b closes the loop by wiring up `dispatch_status`/`execution_result` columns on `tasks` and two new connector-authenticated endpoints that let a paired connector atomically claim a queued task, invoke the CLI, and submit the result back.
+- **Decision**: Add `dispatch_status TEXT NOT NULL DEFAULT 'none'` and `execution_result JSONB` to `tasks` (migration 029). `dispatch_status = 'queued'` is set at task creation when `source` starts with `role_dispatch:`. Ownership is enforced via the `project_members` table throughout (there is no `projects.user_id` column). The atomic claim uses `BEGIN IMMEDIATE` (SQLite) / `FOR UPDATE SKIP LOCKED` (Postgres) via the existing `database.Dialect` pattern. The connector service `RunOnceTask` method integrates into the existing polling loop alongside `RunOnce` (planning run poll). Frontend `DispatchStatusBadge` renders inline next to the task title; `completed` state is expandable to show file paths. `error_kind` validation reuses the existing `AllowedErrorKinds` allowlist from planning runs.
+- **Alternatives considered**: Lease-expiry TTL for tasks (matching planning runs) — deferred; task execution is typically short-lived and the connector loop already handles timeouts via context cancellation. A separate `task_dispatch_log` table for audit history — deferred; `execution_result` JSON on the task row is sufficient for Phase 6b. Role catalog enforcement in the claim handler — deferred; `prompts.Exists` check is in `RunOnceTask` on the connector side, not the server side, because the server does not hold the prompts directory.
+- **Constraints introduced**: Only tasks with `dispatch_status = 'running'` may have results submitted; any other state returns 400. Ownership check uses `project_members` JOIN (not `projects.user_id`). The `NewTaskStoreWithDialect` constructor must be used when dispatch methods are needed; `NewTaskStore` (no dialect) continues to work for code that does not use dispatch. `main.go` uses `NewTaskStoreWithDialect` to ensure the dispatch path is always available in production.

-## 2026-04-17: Real-model planning uses one OpenAI-compatible provider seam
+## 2026-04-27: Phase 6c PR-3 — LLM role router (suggest-only, advisory) [agent:backend-architect]
 
-- **Context**: Planning provider selection already exists in the UI and backend registry, but only a deterministic in-process implementation was available. The system needs a minimal path to use a real model without hard-coding one vendor SDK per provider.
-- **Decision**: Add one optional `openai-compatible` planning provider configured by environment variables (`base URL`, `API key`, model list, timeout). The remote model generates draft content only; the server still owns ranking, scores, confidence, duplicate detection, and typed evidence detail.
-- **Alternatives considered**: Vendor-specific SDK integrations first — rejected because they increase surface area and coupling before the generic provider seam is proven. Let the model own ranking and evidence — rejected because it weakens reproducibility and breaks current review semantics.
-- **Constraints introduced**: Startup must fail fast if `openai-compatible` is selected as the default provider but is not fully enabled. Remote calls must be bounded by timeout and response size. Planning documentation must disclose external context egress when the remote provider is used.
-- **Source**: [agent:backend-architect]
+- **Context**: Operators manually selecting a role for each backlog candidate is friction-heavy and error-prone. Phase 6c PR-3 adds an advisory LLM routing layer that proposes a role without removing the operator's explicit confirmation step.
+- **Decision**: `POST /api/backlog-candidates/:id/suggest-role` runs the dispatcher prompt (in `prompts/meta/dispatcher.md`, category=meta) through the existing `invokeBuiltinCLI` safety boundary and returns `{role_id, confidence, reasoning, alternatives[]}` without persisting the result (API-008: advisory-only). The dispatcher meta-role is added to the catalog (`Category: "meta"`) but filtered out from `GET /api/roles` so it never appears in the role selection dropdown. `SuggestRole` is exported from the `connector` package (wraps `invokeBuiltinCLI`) rather than the `planning` package to avoid leaking subprocess invocation outside the connector boundary. A `roleSuggesterFn` function type is injected into `PlanningRunHandler.WithRoleSuggester(...)` for testability. Frontend: "💡 Suggest role" button appears inside the role_dispatch radio branch; suggestion pre-fills the dropdown + tooltip shows `reasoning` + `alternatives`; operator must still click Save (UI-008). `ErrorKindRouterNoMatch = "router_no_match"` added to `AllowedErrorKinds` so frontend can render advisory UI on no-match. `Auto-apply (mode=role_dispatch_auto)` deferred to Phase 6d per user decision B2.
+- **Constraints introduced**: Dispatcher result is never persisted in 6c; audit row (if any) is written as `actor_kind="user"` after operator confirmation, not `actor_kind="router"`. Prompt embed directive updated to `//go:embed *.md roles/*.md meta/*.md`. `TestMetaRolesHavePromptFiles` added alongside `TestCatalogMatchesPromptDir` to verify the meta/ directory.

-## 2026-04-17: Centralize planning model configuration inside the app
+## 2026-04-27: Phase 6c PR-4 — connector activity tracking
 
-- **Context**: The first real-model slice used deploy-time environment variables for planning provider configuration, but the required workflow is closer to OpenCode: an admin configures model/provider details once in the product, and later agent-backed features consume that saved configuration automatically.
-- **Decision**: Move planning provider configuration into one admin-managed singleton settings record stored in PostgreSQL. New planning runs always resolve provider/model from this central saved configuration. Keep only `APP_SETTINGS_MASTER_KEY` in environment variables so provider API keys can be encrypted at rest.
-- **Alternatives considered**: Keep provider configuration in env vars — rejected because it hard-codes operational details outside the product and prevents the intended setup flow. Keep per-run provider/model overrides — rejected because the desired behavior is central configuration first, then use. Add per-project model settings in v1 — rejected because it increases secret duplication and authorization complexity before the global flow is proven.
-- **Constraints introduced**: `GET` and `PATCH /api/settings/planning` must be admin-only. Stored provider API keys must never be returned by API responses and must be encrypted at rest. No saved settings row means deterministic planning remains the default. If saved remote settings are invalid at runtime, the run must fail rather than silently downgrading to a different provider.
-- **Supersedes**: This decision supersedes the earlier environment-variable-based planning provider configuration decision for active runtime behavior.
+- **Context**: Connector execution is opaque to the browser: the user can see that a connector is online (heartbeat), but not what phase it is currently executing (idle, planning a run, dispatching a task, etc.). The UI needs a lightweight way to show real-time progress without adding another polling loop or requiring the connector to push into the DB synchronously on every phase change.
+- **Decision**: Add a `POST /api/connector/activity` endpoint (connector-token auth) where the connector reports its current `ConnectorActivity` struct. The server maintains an in-memory `activity.Hub` (fan-out pub/sub, same non-blocking drop pattern as `events.Broker`) that holds the latest snapshot per connector and pushes SSE to the browser via `GET /api/me/local-connectors/:id/activity-stream`. A polling fallback `GET /api/me/local-connectors/:id/activity` is also provided. The hub persists snapshots to two new columns on `local_connectors` (`current_activity_json`, `current_activity_at`, migration 031) asynchronously (fire-and-forget goroutine). At startup, persisted snapshots are restored into the hub so state survives a server restart. The connector side introduces `ActivityReporter` with a 500ms coalesce window (same-phase step changes are merged; phase changes flush immediately). `Service.ActivityReporter` is an optional field — nil means no reporting (backwards-compatible). `"online"` definition is `last_seen_at` within 90 seconds (3× the 30s heartbeat interval), consistent with `LocalConnectorLivenessWindow`.
+- **Alternatives considered**: Store activity in a dedicated table per update — rejected because activity is ephemeral and high-frequency; column-on-connector is sufficient for restart recovery. Rate-limit SSE connections — deferred to Phase 6d. Write to `actor_audit` on each activity change — explicitly rejected per the Phase 6c plan (activity is operational telemetry, not an authoring lifecycle event). Synchronous DB persist on POST — rejected because it would block the connector's hot polling loop.
+- **Constraints introduced**: `activity.Hub` is a new top-level package under `internal/activity`; no circular imports. `Persister` is an interface so the hub is testable without a DB. Down migration 031 is a no-op (SQLite `DROP COLUMN` not supported pre-3.35). The `active-connectors` aggregate endpoint is project-scope best-effort (connectors are not yet project-scoped; it returns all user connectors with activity).

-## 2026-04-17: Personal account bindings alongside shared planning settings
+## 2026-04-27: Phase 6c PR-4 — frontend activity hook + badge [agent:application-implementer]
 
-- **Context**: The centralized planning settings singleton only supports one shared API key configured by an admin. Users with personal credentials (or local providers like Ollama that need no API key) cannot bind their own configuration. The project owner has no API keys available — only subscription accounts — so testing requires a no-API-key path (Ollama).
-- **Decision**: Add an `account_bindings` table for per-user credential binding. Extend `planning_settings` with a `credential_mode` column (`shared`, `personal_preferred`, `personal_required`). Credential resolution: personal binding → shared settings → deterministic fallback. Personal API keys use the same `secrets.Box` encryption. CLI bridge for subscription-only accounts (Copilot, ChatGPT desktop) is deferred to a separate design requiring client-side architecture.
-- **Alternatives considered**: Separate provider types per subscription vendor — rejected because subscription logins are not programmatically accessible from a server. Per-project credentials — rejected as premature complexity before global personal bindings are proven. Only support Ollama testing — rejected because the system needs a proper multi-credential architecture regardless.
-- **Constraints introduced**: Personal bindings are user-scoped; admins cannot read other users' plaintext keys. `credential_mode` is global for v1 (not per-project). The existing singleton `planning_settings` row remains the workspace default and is not replaced. Credential resolution must log which binding was used (personal vs shared) in the planning run audit trail.
-- **See also**: `docs/credential-binding-design.md`
-- **Source**: [agent:feature-planner]
+- **Context**: The backend activity hub and SSE endpoint (PR-4 backend) emit `activity` events per connector. The frontend needs a hook that follows the SSE-primary / polling-fallback pattern and a reusable badge component with three density variants.
+- **Decision**: `useConnectorActivity(connectorId)` opens an `EventSource` to `/api/me/local-connectors/:id/activity-stream` and polls `/api/me/local-connectors/:id/activity` every 15 seconds as fallback; stale state (>90s since last update) is surfaced as `source='stale'` for dimmed rendering. Component-level `EventSource` (not App-level) is acceptable here because each badge tracks a distinct connectorId and there is at most one active run per planning session in the local-mode dogfood scope. `ConnectorActivityBadge` renders compact (inline dot + phase name), standard (dot + phase + subject title), or full (expanded with step + stale chip). `PlanningRunList` shows a standard badge on active runs (`status=queued|running`) that have a `connector_id`. Tasks do not carry `connector_id` so task-level integration is deferred until the schema adds it.
+- **Constraints introduced**: `ConnectorPhase` union type and `ConnectorActivityResponse` / `ActiveConnectorEntry` interfaces added to `src/types/index.ts`. API functions `getConnectorActivity`, `listActiveConnectors`, and `connectorActivityStreamURL` added to `src/api/client.ts`. The hook cleans up `EventSource` on unmount; the stale timer fires every 10s to detect dropped connections.

-## 2026-04-17: Subscription path starts with local connector pairing and registry
+## 2026-04-27: Phase 6c PR-5 — dogfood notes + operating-rules + DECISIONS archival [agent:application-implementer]
 
-- **Context**: The project owner is single-user, self-hosting, and has subscription-based model access but no API key. Server-side provider resolution and personal account bindings are insufficient because the server still cannot directly reuse subscription sessions. A practical execution path needs a client-side control boundary before any connector-dispatched planning work can exist.
-- **Decision**: Start the subscription path with a minimal local connector control-plane slice: `local_connectors`, `connector_pairing_sessions`, authenticated user-facing pairing-session creation, connector claim, connector heartbeat, and connector revoke. Use short-lived pairing codes and distinct connector tokens. Defer planning-run dispatch, lease state, and vendor-specific subscription adapters to later slices.
-- **Alternatives considered**: Keep pushing users toward account bindings and local OpenAI-compatible presets only — rejected because it does not solve the subscription-only use case. Add a full connector dispatch system immediately — rejected because it expands scope before pairing and registry are proven. Reuse bearer session tokens for connectors — rejected because connector identity must remain separate from user sessions.
-- **Constraints introduced**: Pairing codes are stored only as hashes and must be single-use with short TTL. Connector presence uses `X-Connector-Token`, not user bearer auth. Batch 1 does not promise subscription execution yet; it only establishes the control-plane seam required for later dispatch.
-- **Source**: [agent:documentation-architect]
+- **Context**: Phase 6c closes 5 PRs (PR-1 catalog+safety, PR-2 authoring, PR-3 router, PR-4 activity, PR-5 docs+archival). PR-5 is the validation + documentation consolidation slice.
+- **Decision**: `docs/phase6c-dogfood-notes.md` documents 7 dogfood steps covering the full role-dispatch path (happy-path, error induction, router suggest UX, activity badge observation). `docs/operating-rules.md` gains a "Role-dispatch safety + visibility model" section covering L0/L1/L2 trigger conditions and activity SSE constraints. `DECISIONS.md` entries before 2026-04-22 are moved to `DECISIONS_ARCHIVE.md` (file was 135KB, well above the 30KB threshold). The affected-tests-only script (`scripts/test-affected.sh` + CI path-filter) ships alongside PR-5 because test infrastructure is a companion deliverable for the phase.
+- **Constraints introduced**: DECISIONS.md archival boundary is 2026-04-22 00:00 UTC; entries on or after that date stay in the active file. `DECISIONS_ARCHIVE.md` receives a new `## Archived on 2026-04-27` section header.

-## 2026-04-25: Phase 6b — role-dispatch task execution loop closed
+## 2026-04-27: Phase 3B PR-2 — context-snapshot endpoint + snapshot save on ClaimNextRun [agent:backend-architect]
+
+- **Context**: PR-1 added the `planning_context_snapshots` table and `PlanningContextV2` wire contract. PR-2 wires snapshot saving and exposes the snapshot as a first-class API resource.
+- **Decision 1 — snapshot save location**: The spec placed snapshot saving in the orchestrator, but the orchestrator does not call `BuildContextV1` — only `LocalConnectorHandler.ClaimNextRun` does (for `local_connector` execution mode runs). Rather than introduce a context builder dependency into the orchestrator (which would complicate its dependency graph and add orchestrator responsibility it doesn't own), snapshot saving is wired in `ClaimNextRun` immediately after `BuildContextV1` succeeds. The `SnapshotSaver` interface + `WithSnapshotSaver` fluent setter ARE added to `Orchestrator` as specified (for future use / non-local paths), but the actual save goes through a `contextSnapshotSaver` interface on `LocalConnectorHandler`. Fire-and-forget semantics preserved: save failure is logged, never propagates to the caller.
+- **Decision 2 — V2 envelope defaults**: `UpgradeV1ToV2` is called with `role=""` (Phase 6c PR-3 will fill this), `IntentModeImplement` (default for local_connector runs), and `scale.EstimateTaskScale(title, description)` from the requirement.
+- **Decision 3 — endpoint**: `GET /api/planning-runs/:id/context-snapshot` is added to `PlanningRunHandler` (not a new handler struct) via `WithContextSnapshotStore(ContextSnapshotGetter)`. Runs with no snapshot return HTTP 200 `{available: false}` (older runs, non-local-connector runs). `?raw=1` returns the raw `PlanningContextV2` JSON blob. Auth follows the same project-member pattern as `PlanningRunHandler.Get`.
+- **Constraints introduced**: `wire` package remains a leaf. `ContextSnapshotGetter` interface lives in `handlers` (not `store`) to avoid store→handlers import. `ContextSnapshotResponse` is exported for test assertions. No schema or migration changes (032 and 033 already existed from PR-1).
+- **Source**: [agent:backend-architect] Phase 3B PR-2 implementation 2026-04-27.
 
-- **Context**: Phase 5 established `execution_role` on `backlog_candidates` as a hint for which prompt role a connector should run. Phase 6b closes the loop by wiring up `dispatch_status`/`execution_result` columns on `tasks` and two new connector-authenticated endpoints that let a paired connector atomically claim a queued task, invoke the CLI, and submit the result back.
-- **Decision**: Add `dispatch_status TEXT NOT NULL DEFAULT 'none'` and `execution_result JSONB` to `tasks` (migration 029). `dispatch_status = 'queued'` is set at task creation when `source` starts with `role_dispatch:`. Ownership is enforced via the `project_members` table throughout (there is no `projects.user_id` column). The atomic claim uses `BEGIN IMMEDIATE` (SQLite) / `FOR UPDATE SKIP LOCKED` (Postgres) via the existing `database.Dialect` pattern. The connector service `RunOnceTask` method integrates into the existing polling loop alongside `RunOnce` (planning run poll). Frontend `DispatchStatusBadge` renders inline next to the task title; `completed` state is expandable to show file paths. `error_kind` validation reuses the existing `AllowedErrorKinds` allowlist from planning runs.
-- **Alternatives considered**: Lease-expiry TTL for tasks (matching planning runs) — deferred; task execution is typically short-lived and the connector loop already handles timeouts via context cancellation. A separate `task_dispatch_log` table for audit history — deferred; `execution_result` JSON on the task row is sufficient for Phase 6b. Role catalog enforcement in the claim handler — deferred; `prompts.Exists` check is in `RunOnceTask` on the connector side, not the server side, because the server does not hold the prompts directory.
-- **Constraints introduced**: Only tasks with `dispatch_status = 'running'` may have results submitted; any other state returns 400. Ownership check uses `project_members` JOIN (not `projects.user_id`). The `NewTaskStoreWithDialect` constructor must be used when dispatch methods are needed; `NewTaskStore` (no dialect) continues to work for code that does not use dispatch. `main.go` uses `NewTaskStoreWithDialect` to ensure the dispatch path is always available in production.

+## Archived on 2026-04-27
+
+## 2026-04-21: Four UI progressive-disclosure improvements [agent:application-implementer]
+
+- **Context**: `SyncStatusPanel` always rendered as a full card regardless of whether attention was needed. The Settings tab rendered outside the rail layout, visually misaligned. The Planning intake form was always visible even when requirements already existed. The Drift Document Preview always rendered inline, adding noise to the detail panel.
+- **Decision**:
+  - (1) `SyncStatusPanel` is now collapsible. It auto-expands when action is needed (`!hasRepoSource || !latestSyncRun || latestSyncRun.status === 'failed' || canApplyDetectedBranchAndRerun`) and otherwise renders as a compact bar with a status badge, relative time, error hint, drift badge, Sync Now button, and a Details button. The expanded view retains all original content plus a Collapse button.
+  - (2) The Settings tab content (Repo Mappings card) was relocated from above the rail layout to inside the rail content area, after the Agents tab block. It now renders correctly within the rail flow.
+  - (3) The Planning Requirement Intake form uses sequential disclosure when requirements already exist: the form is hidden behind a `+ New Requirement` button (`showRequirementIntake` state, default false when requirements exist). After a successful create the form auto-collapses. When no requirements exist the form remains fully visible.
+  - (4) The Drift detail Document Preview section now shows a toggle button (`Show Document Preview` / `Hide Preview`) instead of always rendering the `
` block. The preview collapses automatically when the user selects a different drift signal.
+- **Constraints introduced**: `showDriftPreview` and `showRequirementIntake` are local state in `ProjectDetail.tsx`; no state was lifted to parent/child components. `SyncStatusPanel` initializes `expanded` via a `useState` initializer function (runs once on mount, not reactively). If the conditions that would auto-expand change after mount (e.g., sync fails while the panel is already collapsed), the panel does not auto-re-expand — the user must click Details. This is intentional; re-expansion on state change would be disruptive.
+
+## 2026-04-21: Server-side LLM provider must apply wire sanitizer + request body cap
+
+- **Context**: `OpenAICompatibleProvider` built its outbound prompt directly from the internal `PlanningContext` via `compactX` helpers. `AgentRun.Summary` and `SyncRun.ErrorMessage` were truncated only by char count; `wire.RedactSecrets` (used on the local-connector path) was not applied. There was also no upper bound on the marshalled request body, so a pathological project with very large summaries could egress unbounded bytes to the configured remote endpoint. The local connector path (`BuildContextV1` → wire sanitizer → `ReduceSources` 256 KiB cap) was strictly safer than the server path that called the same model — an asymmetry that violated the "context.v1 is the single sanitization contract" intent of the 2026-04-20 sanitizer decision.
+- **Decision**: (a) Export `wire.RedactSecrets` and `wire.TruncateRunes` so non-wire callers can apply the same v1 redaction without owning the regex set. (b) `OpenAICompatibleProvider.compactSyncRunForPrompt` and `compactAgentRunsForPrompt` now redact and truncate using those helpers (caps `wire.MaxSyncRunErrorChars` / `wire.MaxAgentRunSummaryChars`). (c) `OpenAICompatibleProvider.Generate` enforces `defaultOpenAICompatibleMaxRequestBytes = 256 KiB` on the marshalled request body and returns a typed error instead of egressing the over-cap payload. The cap mirrors `wire.DefaultMaxSourcesBytes` so server- and connector-path egress budgets stay aligned. (d) `ProjectContextBuilder.Build` no longer silently swallows store errors for documents/drift/sync/agent-runs; it logs and accumulates a per-source warning string. `BuildContextV1` propagates those warnings into `wire.PlanningContextMeta.Warnings`, giving adapters a deterministic degraded-mode signal. (e) Router CORS replaced the `AllowedOrigins:["*"] + AllowCredentials:true` combination (which browsers reject) with an env-driven allowlist (`CORS_ALLOWED_ORIGINS`) and safe localhost defaults; a literal `*` allowlist now disables credentialed CORS instead of silently breaking auth.
+- **Alternatives considered**: (1) Promote `wire.PlanningContextV1` as the only input to providers (full Tier-2 refactor that would also let `Provider.Generate` accept `context.Context`) — deferred. The interface change rippled through 4 implementations and 5 tests for marginal additional safety on top of (a)–(c); it is recorded as the next step rather than blocking these fixes. (2) Leave silent error swallowing in the context builder and rely on logs alone — rejected; adapters need a structured signal to mark a recommendation as evidence-degraded.
+- **Constraints introduced**: All new server-side LLM providers MUST sanitize free-form fields with `wire.RedactSecrets` before egress and MUST enforce a request body cap no larger than `wire.DefaultMaxSourcesBytes`. `wire.PlanningContextMeta.Warnings` is now part of the wire contract — adapters MUST tolerate the field but MAY ignore it. Production deployments MUST set `CORS_ALLOWED_ORIGINS` to the canonical UI host(s); leaving it unset preserves localhost-only behavior, which is unsafe for any non-development deployment. Reference adapters (`adapters/*.py`) are now committed with executable permission bits to avoid the exit-126 failure mode that surfaced when the connector serve loop tried to spawn them on a fresh checkout.
+
+## 2026-04-20: Local connector planning runs emit in-app notifications; FE auto-refreshes the badge
+
+- **Context**: The notification model, store, REST endpoints, and bell-badge UI were fully implemented, but no caller in the planning flow ever invoked `NotificationStore.Create`, and `App.tsx` only fetched the unread count once at bootstrap. End users running planning via a paired local connector therefore had no signal that a run finished unless they were already on the project page.
+- **Decision**: When a local-connector planning run reaches a terminal state inside `LocalConnectorHandler.SubmitPlanningRunResult`, emit a best-effort notification scoped to the run's `requested_by_user_id` (falling back to the connector owner). Success uses `kind=info` with the candidate count and a deep link to `/projects/{project_id}`; failure uses `kind=error` with a truncated error message. Notification delivery never blocks run finalization — failures are logged and swallowed. On the frontend, `App.tsx` polls `getUnreadCount` every 20 s while the user is signed in, refreshes immediately on `visibilitychange`, and exposes a `anpm:refresh-notifications` window event that `ProjectDetail.tsx` dispatches the moment a watched run flips from active to terminal. The same transition surfaces a one-shot success/failure flash banner on the run card.
+- **Alternatives considered**: (a) Server-Sent Events / WebSockets for push-based notifications — deferred; polling is sufficient for MVP and avoids a new transport layer. (b) Emit notifications inside `PlanningRunStore.CompleteLocalConnectorRun` to also cover server-provider runs uniformly — rejected for now; coupling persistence to side effects fights the layering and the server-provider path can be revisited when a parity gap actually shows up.
+- **Constraints introduced**: Notification kind must remain in the `info | warning | error | drift | agent` enum; the helper currently uses `info`/`error`. The frontend custom event name `anpm:refresh-notifications` is a stable contract — any other page that wants to bump the unread badge must dispatch the same event.
+
+## 2026-04-20: Local connector is user-scoped, serves all of a user's projects
+
+- **Context**: Users asked whether a paired connector handles one project or many, and how to run concurrent planning runs across projects. The claim endpoint also previously dropped `planning_context` on its way into the adapter (a service-layer regression in `RunOnce`).
+- **Decision**: A paired local connector is scoped to the owning user, not to a project. `LeaseNextLocalConnectorRun` already selects the oldest queued run across the user's entire account; this is affirmed as intentional. The `claim-next-run` response now also carries the owning `Project` (id, name, description) so adapters and connector logs can identify which project the current run belongs to. `Service.RunOnce` forwards both `Project` and `PlanningContext` into `ExecJSONInput`, fixing a latent bug that dropped the planning context.
+- **Alternatives considered**: (a) Introduce per-connector project allowlists — rejected for MVP; adds schema + UX surface with no concrete use case yet. (b) Make the connector multiplex parallel runs — rejected; single-threaded FIFO keeps resource usage predictable on a developer laptop. Parallelism is achieved by pairing additional devices.
+- **Constraints introduced**: Concurrent planning across projects on a single device is serialized (FIFO). Operators who need real parallelism must pair multiple devices, each running its own `bin/anpm-connector serve`. Docker-compose is supported for the server but the connector intentionally runs on the host where the agent CLI is authenticated (e.g. where `claude login` has stored credentials).
+
+## 2026-04-20: Ship reference `adapters/backlog_adapter.py` for local connector
+
+- **Context**: The local connector speaks the `exec-json` contract, but operators had nothing concrete to plug into `--adapter-command`. Users cannot evaluate the end-to-end loop without building their own adapter.
+- **Decision**: Ship `adapters/backlog_adapter.py` — a Python 3 reference adapter that reads the `exec-json` request (including `planning_context`), shells out to the Claude Code CLI (default) or Codex CLI (`ANPM_ADAPTER_AGENT=codex`), and parses ranked backlog candidates from a fenced JSON code block. User-supplied adapters remain fully supported as long as they honor the same stdin/stdout contract.
+- **Alternatives considered**: (a) Ship a Go-based adapter binary — rejected; Python keeps the reference implementation easy to fork and read, and the contract is language-agnostic. (b) Build an HTTP-based adapter calling OpenAI-compatible endpoints — rejected for v1 because Claude/Codex CLIs already own auth + model selection on the operator's machine, avoiding a second credential surface.
+- **Constraints introduced**: Adapter output is normalized before reaching the server: `priority_score`/`confidence` clamped to `[0,1]`, title truncated to 120 chars, evidence ids coerced to strings, errors surfaced via `error_message` with exit code 0. Frontend `ProjectDetail.tsx` auto-polls every 3 s while a planning run is `queued`/`leased`/`running` so connector results surface without manual reload.
+
+## 2026-04-20: Adopt `context.v1` as local connector planning context contract
+
+- **Context**: Local connector adapters (`exec-json`) currently receive only `{run, requirement}` and cannot produce high-quality backlog candidates grounded in project state. The MVP core capability "agent auto-decomposes requirements into backlog" requires structured project context.
+- **Decision**: Introduce a versioned `planning_context` payload (`schema_version: "context.v1"`) attached to `POST /api/connector/claim-next-run` responses and forwarded through adapter stdin. Source of truth: `docs/local-connector-context.md`.
+- **Alternatives considered**: (a) Re-use `PlanningContext` directly as the wire type — rejected because it would pull server-only planning code into the connector binary. (b) Let adapters query server APIs for context — rejected because adapters are external processes without session tokens.
+- **Constraints introduced**: Wire DTOs must live in a leaf package (`backend/internal/planning/wire`) that imports only `models`; `planning` and `connector` both import `wire`, never each other. Adapters MUST ignore unknown fields and MUST treat missing `planning_context` as degraded-but-OK mode.
+
+## 2026-04-20: Metadata-only documents in local connector context
+
+- **Context**: Document bodies can be large, may contain sensitive content, and are not consistently useful to backlog decomposition.
+- **Decision**: Phase A of `context.v1` sends documents as metadata only (title, file_path, doc_type, is_stale, staleness_days) — matching existing `compactDocumentsForPrompt` in `openai_compatible_provider.go`. Body transmission is deferred to a future opt-in design.
+- **Alternatives considered**: Send full bodies with size cap — rejected; cap alone does not address sensitivity and regresses relative to current server-side provider behavior.
+- **Constraints introduced**: Adapter-generated backlog candidates must rely on title + path + staleness to cite documents as evidence. File-path-based reading is the adapter's own responsibility if it has filesystem access.
+
+## 2026-04-20: Context sanitizer v1 scope and excluded bare hex regex
+
+- **Context**: Free-form strings in `AgentRun.Summary` and `SyncRun.ErrorMessage` occasionally contain secret-shaped substrings (API keys, bearer tokens, basic-auth URLs). Earlier plan draft included a bare `\b[A-Fa-f0-9]{32,}\b` regex that would destroy 40-char git commit SHAs and legitimate hashes in diagnostic text.
+- **Decision**: Phase A sanitizer scope limited to `AgentRun.Summary` and `SyncRun.ErrorMessage`. Regex set is prefix-anchored: OpenAI `sk-…`, AWS `AKIA…`, PEM headers, `bearer ` (≥16 chars), basic-auth URLs, labeled secrets (`password=`, `token:`, `api_key=`), `sha256:` labeled hashes, `Authorization:` header dumps. Bare hex regex is explicitly excluded. Sanitizer version constant: `"v1"`.
+- **Alternatives considered**: Aggressive entropy-based redaction — rejected for false-positive rate. No sanitizer — rejected because `AgentRun.Summary` is agent-generated and known to occasionally leak auth errors verbatim.
+- **Constraints introduced**: Any change to the regex set requires a sanitizer version bump and a new DECISIONS.md entry.
+
+## 2026-04-20: Connector context byte cap applies to `sources` only
+
+- **Context**: `planning_context` has scaffolding (schema_version, limits, meta) plus `sources`. Applying a single cap to the whole payload creates pathological cases where scaffolding overhead alone exceeds the cap.
+- **Decision**: `max_sources_bytes` (256 KiB default) applies only to the marshaled `sources` object. Scaffolding and envelope are excluded from the cap. `meta.sources_bytes` records the final size. Reducer drops lowest-rank items from the largest-in-bytes source, re-measured each round.
+- **Alternatives considered**: Cap on full payload — rejected per above. No cap — rejected because a runaway project with thousands of drift signals could produce multi-megabyte payloads and break adapter stdin.
+- **Constraints introduced**: Adapters must be prepared to receive `dropped_counts` > 0 and cannot rely on "all open drift signals" being present.
+
+## 2026-04-14: Use SQLite as Phase 1 data store
+
+- **Context**: Need a lightweight database that avoids extra containers and keeps RAM usage low.
+- **Decision**: Use SQLite for Phase 1-3. Migrate to PostgreSQL in Phase 4 if concurrent write throughput becomes a bottleneck.
+- **Alternatives considered**: PostgreSQL from day one — rejected because it adds a container and ~200MB RAM for a system that initially serves a single user or small team.
+- **Constraints introduced**: All SQL must be compatible with SQLite. Use `database/sql` with a driver that supports both SQLite and PostgreSQL to ease future migration.
+
+## 2026-04-14: Move backend runtime to PostgreSQL now
+
+- **Context**: The project already reached Phase 4 capabilities (sessions, RBAC, full-text search, agent lifecycle) and now needs production-aligned behavior for concurrent access and reliable full-text querying.
+- **Decision**: Use PostgreSQL as the backend runtime database now, including local Docker Compose development. Migrations and runtime SQL use PostgreSQL semantics (`$N` placeholders, `BOOLEAN`, `TIMESTAMPTZ`, Postgres full-text search).
+- **Alternatives considered**: Keep SQLite through additional phases — rejected because it complicates correctness for search and boolean handling while increasing migration risk later.
+- **Supersedes**: This decision supersedes the earlier "Use SQLite as Phase 1 data store" decision for active runtime defaults.
+- **Constraints introduced**: Docker runtime requires a PostgreSQL service and `DATABASE_URL`. Data reset/re-seeding is required when moving existing local SQLite state.
+
+## 2026-04-14: Scrum-first backlog-before-implementation workflow
+
+- **Context**: Implementation often started before clear backlog capture and prioritization, causing requirement backfill after coding.
+- **Decision**: Enforce a Scrum-first execution order: discover, triage, check decisions, capture backlog, prioritize backlog, then implement.
+- **Alternatives considered**: Implementation-first with post-hoc planning — rejected due to rework and unclear priorities.
+- **Constraints introduced**: Tasks are not considered implementation-ready until backlog items and acceptance criteria are explicitly recorded.
+- **Source**: [agent:documentation-architect]
+
+## 2026-04-17: Apply approved planning output at candidate scope
+- **Context**: Phase 2 planning review persists multiple backlog candidates per requirement and per planning run. A requirement-scoped apply contract would mix one-to-many planning state with a bulk side effect before the aggregate rules are settled.
+- **Decision**: Apply approved planning output with `POST /api/backlog-candidates/:id/apply`. The operation creates at most one task, writes one `task_lineage` record, marks that candidate `applied`, and is idempotent for retries of the same candidate.
+- **Alternatives considered**: `POST /api/requirements/:id/apply` bulk apply — rejected because it couples candidate review state to requirement-wide mutation too early. Auto-promote requirement status to `planned` on first apply — rejected because a requirement may have multiple candidates or multiple planning runs and the aggregate rule is not yet defined.
+- **Constraints introduced**: Only `approved` candidates may be applied. Duplicate open tasks are blocked by normalized-title conflict detection within the project. Requirement status remains unchanged during candidate apply until a separate aggregate rule is introduced.
+## 2026-04-17: Real-model planning uses one OpenAI-compatible provider seam
+- **Context**: Planning provider selection already exists in the UI and backend registry, but only a deterministic in-process implementation was available. The system needs a minimal path to use a real model without hard-coding one vendor SDK per provider.
+- **Decision**: Add one optional `openai-compatible` planning provider configured by environment variables (`base URL`, `API key`, model list, timeout). The remote model generates draft content only; the server still owns ranking, scores, confidence, duplicate detection, and typed evidence detail.
+- **Alternatives considered**: Vendor-specific SDK integrations first — rejected because they increase surface area and coupling before the generic provider seam is proven. Let the model own ranking and evidence — rejected because it weakens reproducibility and breaks current review semantics.
+- **Constraints introduced**: Startup must fail fast if `openai-compatible` is selected as the default provider but is not fully enabled. Remote calls must be bounded by timeout and response size. Planning documentation must disclose external context egress when the remote provider is used.
+- **Source**: [agent:backend-architect]
+## 2026-04-17: Centralize planning model configuration inside the app
+- **Context**: The first real-model slice used deploy-time environment variables for planning provider configuration, but the required workflow is closer to OpenCode: an admin configures model/provider details once in the product, and later agent-backed features consume that saved configuration automatically.
+- **Decision**: Move planning provider configuration into one admin-managed singleton settings record stored in PostgreSQL. New planning runs always resolve provider/model from this central saved configuration. Keep only `APP_SETTINGS_MASTER_KEY` in environment variables so provider API keys can be encrypted at rest.
+- **Alternatives considered**: Keep provider configuration in env vars — rejected because it hard-codes operational details outside the product and prevents the intended setup flow. Keep per-run provider/model overrides — rejected because the desired behavior is central configuration first, then use. Add per-project model settings in v1 — rejected because it increases secret duplication and authorization complexity before the global flow is proven.
+- **Constraints introduced**: `GET` and `PATCH /api/settings/planning` must be admin-only. Stored provider API keys must never be returned by API responses and must be encrypted at rest. No saved settings row means deterministic planning remains the default. If saved remote settings are invalid at runtime, the run must fail rather than silently downgrading to a different provider.
+- **Supersedes**: This decision supersedes the earlier environment-variable-based planning provider configuration decision for active runtime behavior.
+## 2026-04-17: Personal account bindings alongside shared planning settings
+
+- **Context**: The centralized planning settings singleton only supports one shared API key configured by an admin. Users with personal credentials (or local providers like Ollama that need no API key) cannot bind their own configuration. The project owner has no API keys available — only subscription accounts — so testing requires a no-API-key path (Ollama).
+- **Decision**: Add an `account_bindings` table for per-user credential binding. Extend `planning_settings` with a `credential_mode` column (`shared`, `personal_preferred`, `personal_required`). Credential resolution: personal binding → shared settings → deterministic fallback. Personal API keys use the same `secrets.Box` encryption. CLI bridge for subscription-only accounts (Copilot, ChatGPT desktop) is deferred to a separate design requiring client-side architecture.
+- **Alternatives considered**: Separate provider types per subscription vendor — rejected because subscription logins are not programmatically accessible from a server. Per-project credentials — rejected as premature complexity before global personal bindings are proven. Only support Ollama testing — rejected because the system needs a proper multi-credential architecture regardless.
+- **Constraints introduced**: Personal bindings are user-scoped; admins cannot read other users' plaintext keys. `credential_mode` is global for v1 (not per-project). The existing singleton `planning_settings` row remains the workspace default and is not replaced. Credential resolution must log which binding was used (personal vs shared) in the planning run audit trail.
+- **See also**: `docs/credential-binding-design.md`
+- **Source**: [agent:feature-planner]
+## 2026-04-17: Subscription path starts with local connector pairing and registry
+- **Context**: The project owner is single-user, self-hosting, and has subscription-based model access but no API key. Server-side provider resolution and personal account bindings are insufficient because the server still cannot directly reuse subscription sessions. A practical execution path needs a client-side control boundary before any connector-dispatched planning work can exist.
+- **Decision**: Start the subscription path with a minimal local connector control-plane slice: `local_connectors`, `connector_pairing_sessions`, authenticated user-facing pairing-session creation, connector claim, connector heartbeat, and connector revoke. Use short-lived pairing codes and distinct connector tokens. Defer planning-run dispatch, lease state, and vendor-specific subscription adapters to later slices.
+- **Alternatives considered**: Keep pushing users toward account bindings and local OpenAI-compatible presets only — rejected because it does not solve the subscription-only use case. Add a full connector dispatch system immediately — rejected because it expands scope before pairing and registry are proven. Reuse bearer session tokens for connectors — rejected because connector identity must remain separate from user sessions.
+- **Constraints introduced**: Pairing codes are stored only as hashes and must be single-use with short TTL. Connector presence uses `X-Connector-Token`, not user bearer auth. Batch 1 does not promise subscription execution yet; it only establishes the control-plane seam required for later dispatch.

+# Role Dispatcher
+
+## Role
+You are a task classifier. Given a task title, description, upstream requirement, and project context, you identify which execution role from the catalog is best suited to complete the task.
+
+## Objective
+Analyze the task and return exactly one JSON block naming the best role, your confidence, a brief reasoning, and up to two alternatives when the decision is not clear-cut.
+
+## Available roles
+{{ROLE_CATALOG}}
+
+## Inputs
+- Task: `{{TASK_TITLE}}`
+- Details: `{{TASK_DESCRIPTION}}`
+- Upstream requirement: `{{REQUIREMENT}}`
+- Project context: `{{PROJECT_CONTEXT}}`
+
+## Output format
+One JSON object inside a single ```json fenced code block:
+```
+{
+  "role_id": "",
+  "confidence": <0.0–1.0>,
+  "reasoning": "",
+  "alternatives": [
+    {"role_id": "", "reason": "", "score": <0.0–1.0>}
+  ]
+}
+```
+
+## Constraints
+- `role_id` MUST be one of the exact IDs listed in Available roles above. Do not invent new IDs.
+- `confidence` 1.0 = perfect fit; 0.0 = wild guess. Be calibrated: a task that is clearly about writing tests is 0.95+ for test-writer, not 1.0.
+- `alternatives` is empty `[]` when confidence ≥ 0.85 (the best role is clearly dominant). Include at most two alternatives, scored lower than `role_id`.
+- If no role fits even loosely (e.g. the task is purely organisational, or the description is blank), return `role_id: ""` and `confidence: 0`.
+- One JSON block only. No prose outside the block, no markdown except the fenced block.

+- Rationale: Centralises connection lifecycle; components can subscribe/unsubscribe independently without re-creating the connection. Mirrors the existing `anpm:refresh-notifications` pattern.

Subject: [PATCH 2/5] feat(phase6c-pr4): connector activity SSE + badge +
 dogfood notes

Add ActivityHub (SSE fan-out) + ActivityReporter so local connectors can
stream real-time phase/step updates. GET /api/me/local-connectors/:id/activity-stream
serves the SSE channel; GET /activity returns the latest snapshot.
Frontend: useConnectorActivity hook (SSE-primary, 15 s poll fallback, 90 s
stale detection) + ConnectorActivityBadge (compact/standard/full variants).
Badge shown inline on active planning runs in PlanningRunList. Dogfood
checklist added in docs/phase6c-dogfood-notes.md; operating-rules and
rules-quickstart updated with activity-SSE and advisory-router constraints.
CI workflow and Makefile gain affected-test helpers.

+## Role-dispatch safety + visibility model
+
+Added in Phase 6c. Governs how roles are assigned, validated, and monitored during task dispatch.
+
+### L0 — subprocess safety boundary (Phase 6c PR-1)
+
+Applied inside `invokeBuiltinCLI` for every CLI invocation:
+
+| Constraint | Default | Override env var |
+|---|---|---|
+| Wall-clock timeout | per-role `DefaultTimeoutSec` | `ANPM_DISPATCH_TIMEOUT` (0 = disabled) |
+| Output cap | 5 MB | `ANPM_DISPATCH_MAX_OUTPUT_BYTES` (0 = disabled) |
+| Result schema validation | strict | not configurable |
+| SIGTERM → SIGKILL escalation | 5s | not configurable |
+
+**L0 is unconditional** — it applies to all CLI invocations regardless of role or connector. Operators can increase limits via env vars but cannot disable them in production without modifying source.
+
+**L1 (process-level jail)** and **L2 (container/VM isolation)** are deferred to Phase 6d / Phase 7.
+
+### L1 trigger conditions (Phase 6d)
+
+L1 activates when any of the following occur:
+- A connector executes external code from an untrusted source (non-catalog adapter).
+- Multi-tenancy is introduced (multiple users sharing a server).
+- A Phase 6d dogfood run shows L0 is being consistently bypassed.
+
+### L2 trigger conditions (Phase 7)
+
+L2 activates when:
+- The system accepts tasks from untrusted external repositories.
+- Compliance or legal requirements mandate isolation.
+
+### Catalog enforcement points
+
+`roles.IsKnown(roleID)` is checked at four points:
+
+1. **PATCH /api/backlog-candidates/:id** — when `execution_role` is set via the editor.
+2. **POST /api/backlog-candidates/:id/apply** — when mode=role_dispatch; missing role → 400.
+3. **POST /api/connector/claim-next-task** — when the task source includes a role suffix; stale role → `MarkTaskRoleNotFound` → `dispatch_status=failed`.
+4. **`invokeBuiltinCLI`** — checks `prompts.Exists(roleID)` before spawning subprocess.
+
+Empty role suffix (`role_dispatch:` without a role id) is treated as `error_kind=role_dispatch_malformed` at points 3 and 4.
+
+### Actor audit (Phase 6c PR-2)
+
+Every `execution_role` change is recorded in `actor_audit` with:
+- `actor_kind`: `user` (session), `api_key` (automation), `system` (claim-time enforcement), `connector` (connector-reported).
+- `actor_kind=router` is reserved for Phase 6d auto-apply; no code writes it in Phase 6c.
+- Audit rows are append-only; no cascade-delete with the subject row.
+
+### Activity SSE constraints (Phase 6c PR-4)
+
+| Constraint | Value | Notes |
+|---|---|---|
+| Heartbeat interval | 30s | SSE keepalive comment |
+| Stale threshold | 90s | 3× heartbeat; frontend dims badge |
+| Polling fallback interval | 15s | kicks in when SSE fails |
+| Coalesce window | 500ms | same-phase step changes merged by connector |
+| Phase changes | always enqueued | phase changes never coalesced |
+| Concurrent SSE per user | ≤ 3 (planned) | deferred to Phase 6d rate limiting |
+| Activity history | latest snapshot only | full history deferred to Phase 6d |
+
+**Activity is operational telemetry**, not an authoring lifecycle event. It is never written to `actor_audit`. The server persists only the latest snapshot per connector to `local_connectors.current_activity_json`.
+
+### Advisory router constraints (Phase 6c PR-3)
+
+- `POST /api/backlog-candidates/:id/suggest-role` is advisory-only; it never persists a result.
+- The operator must explicitly confirm the suggestion before it is saved (UI-008).
+- Router errors (`dispatch_timeout`, `output_too_large`, `invalid_result_schema`) surface in the suggest response body, not as 4xx/5xx HTTP errors (API-008).
+- `router_no_match` is a valid outcome when the dispatcher prompt returns `role_id = "no_match"`.
+- Auto-apply mode (`role_dispatch_auto`) is deferred to Phase 6d.

+# Phase 6c Dogfood Notes
+
+**Status**: template (to be filled during dogfood run)
+**Date**: 2026-04-27
+**Phase**: 6c (PR-1 through PR-4 merged)
+
+These notes record the 7 dogfood steps designed to validate the Phase 6c feature set end-to-end. Each step has a setup, expected outcome, and space for observations.
+
+---
+
+## Step 1 — Role-dispatch happy path
+
+**Goal**: Confirm role_dispatch execution works end-to-end from UI through connector.
+
+**Setup**:
+1. Start `anpm-server` and `anpm-connector serve` on a paired device.
+2. Create a requirement, run planning, and approve a backlog candidate.
+3. In CandidateReviewPanel, select execution_mode=role_dispatch and pick `backend-architect`.
+4. Click Apply.
+
+**Expected outcome**:
+- Task created with `source = "role_dispatch:backend-architect"` and `dispatch_status = "queued"`.
+- Connector claims the task (`dispatch_status → running`), invokes the CLI with the backend-architect prompt.
+- Task completes with `dispatch_status = "completed"` and `execution_result.success = true`.
+
+**Observations**:
+
+
+---
+
+## Step 2 — role_not_found error induction
+
+**Goal**: Trigger `role_not_found` by applying with a role that no longer exists.
+
+**Setup**:
+1. Apply a candidate with `execution_role = "nonexistent-role"` via the PATCH API directly, bypassing UI enforcement.
+   ```
+   curl -X PATCH .../api/backlog-candidates/{id} -d '{"execution_role": "nonexistent-role"}'
+   ```
+2. Then apply that candidate with execution_mode=role_dispatch.
+
+**Expected outcome**:
+- Server returns 400 with "role not in catalog" message.
+- If a task was somehow queued, connector marks it `dispatch_status = "failed"` with `error_kind = "role_not_found"`.
+- Remediation hint points to the catalog.
+
+**Observations**:
+
+
+---
+
+## Step 3 — dispatch_timeout induction
+
+**Goal**: Trigger `dispatch_timeout` by running a long-running CLI with a short timeout.
+
+**Setup**:
+1. Set environment variable `ANPM_DISPATCH_TIMEOUT=10s` on the connector host.
+2. Use a role that invokes a slow CLI (e.g., add `sleep 30` to the adapter command).
+3. Apply a candidate with that role and wait for the task to be claimed.
+
+**Expected outcome**:
+- Task fails with `error_kind = "dispatch_timeout"` after 10s.
+- `execution_result.error_kind = "dispatch_timeout"`.
+- Remediation hint suggests checking `ANPM_DISPATCH_TIMEOUT`.
+
+**Observations**:
+
+
+---
+
+## Step 4 — output_too_large induction
+
+**Goal**: Trigger `output_too_large` by having the CLI print excessive output.
+
+**Setup**:
+1. Replace the adapter command with a script that prints ~6 MB to stdout:
+   ```bash
+   #!/bin/bash
+   python3 -c "print('x' * 6000000)"
+   ```
+2. Apply a candidate with this role.
+
+**Expected outcome**:
+- Task fails with `error_kind = "output_too_large"`.
+- Output is truncated; the raw cap value appears in the remediation hint.
+
+**Observations**:
+
+
+---
+
+## Step 5 — invalid_result_schema induction
+
+**Goal**: Trigger `invalid_result_schema` by having the CLI print malformed JSON.
+
+**Setup**:
+1. Replace the adapter command with a script that prints invalid JSON:
+   ```bash
+   #!/bin/bash
+   echo "this is not json"
+   ```
+2. Apply a candidate with this role.
+
+**Expected outcome**:
+- Task fails with `error_kind = "invalid_result_schema"`.
+- Remediation hint explains the expected JSON structure.
+
+**Observations**:
+
+
+---
+
+## Step 6 — Router suggest button
+
+**Goal**: Validate that the "💡 Suggest role" button works and the advisory UX is correct.
+
+**Setup**:
+1. Create a requirement with a clear technical description (e.g., "Implement the authentication middleware using JWT tokens with refresh logic").
+2. Run planning to produce a backlog candidate.
+3. In CandidateReviewPanel, select execution_mode=role_dispatch.
+4. Click "💡 Suggest role" (without having selected a role first).
+
+**Expected outcome**:
+- The button shows a loading state during the LLM call.
+- The dropdown pre-fills with the suggested role (e.g., `backend-architect`).
+- A tooltip or inline section shows confidence (e.g., 85%), reasoning, and 1–2 alternatives.
+- The save button remains required; the suggestion is not auto-applied.
+- Clicking an alternative from the suggestion section sets the dropdown to that role.
+
+**Variations to try**:
+- Task with ambiguous description → expect low confidence or `no_match`.
+- Task clearly matching `ui-scaffolder` vs `backend-architect`.
+
+**Observations**:
+
+
+---
+
+## Step 7 — ConnectorActivityBadge phase transitions
+
+**Goal**: Observe the activity badge update in real time as the connector progresses through phases.
+
+**Setup**:
+1. Apply a candidate with execution_mode=role_dispatch.
+2. Open the Planning tab and watch the active planning run card.
+3. Observe the `ConnectorActivityBadge` as the connector transitions:
+   - `idle` (before claim)
+   - `claiming_run` (connector polling)
+   - `planning` (if connector runs a planning phase)
+   - `claiming_task` (claiming the dispatched task)
+   - `dispatching` (CLI executing)
+   - `submitting` (writing result back)
+   - `idle` (after completion)
+
+**Expected outcome**:
+- Badge phase label updates within ~1s of each transition.
+- Badge dims to "stale" if 90s pass without an update.
+- Phase sequence matches expected flow (no phases skipped or repeated unexpectedly).
+- After connector returns to idle, badge shows `● idle`.
+
+**What to record**:
+- Phase transition latency (from connector phase change to badge update).
+- Any transitions that appear to be missing or duplicated.
+- Whether SSE connection drops and polling fallback kicks in.
+
+**Observations**:
+
+
+---
+
+## Summary
+
+| Step | Feature | Status | Notes |
+|------|---------|--------|-------|
+| 1 | Role-dispatch happy path | pending | |
+| 2 | role_not_found induction | pending | |
+| 3 | dispatch_timeout induction | pending | |
+| 4 | output_too_large induction | pending | |
+| 5 | invalid_result_schema induction | pending | |
+| 6 | Router suggest button UX | pending | |
+| 7 | Activity badge phase transitions | pending | |
+
+## Phase 6d trigger signals to watch
+
+While running these steps, note:
+- Any case where the router suggests a role with high confidence but the suggestion is clearly wrong (→ Phase 6d adversarial corpus)
+- Any activity phase transition that takes >2s to appear (→ Phase 6d coalesce tuning)
+- Any case where the operator wishes the suggestion was auto-applied (→ Phase 6d auto-apply signal)

Subject: [PATCH 3/5] feat(phase3b): context pack v2 + evidence panel +
 candidate feedback + quality view
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PR-1 — PlanningContextV2 wire struct (schema_version, pack_id, role,
intent_mode, task_scale, source_of_truth[]) + scale.EstimateTaskScale
heuristic (word-count + keyword overrides). Migrations 032/033 add
planning_context_snapshots table and context_pack_id column on planning_runs.
ContextSnapshotStore Save/GetByRunID.

PR-2 — GET /api/planning-runs/:id/context-snapshot returns structured
evidence (sources, counts, role, intent_mode, task_scale). Snapshot saved
fire-and-forget in ClaimNextRun where V1 context is built; Orchestrator
gets SnapshotSaver interface as hook for future server-provider path.

PR-3 — Migration 034 adds feedback_kind/feedback_note columns on
backlog_candidates. Optional feedback popover in CandidateReviewPanel
(skippable, never blocks approve/reject). QualitySummary computed in
PlanningRunStore.GetByID; quality row shown in PlanningRunList once all
candidates are reviewed.

PR-4 — DashboardSummary gains avg_planning_acceptance_rate and
planning_runs_reviewed_count (7-day window, CASE WHEN for
SQLite+Postgres compat). ProjectOverviewTab shows acceptance rate inline.

When no snapshot exists (run predates Phase 3B or is not a local_connector run), returns `{ available: false }` with HTTP 200. Nonexistent run returns 404. Query param `?raw=1` returns the raw `PlanningContextV2` JSON blob as `data`. Snapshots are saved fire-and-forget on `ClaimNextRun` after a successful `BuildContextV1` call.
 - `PATCH /api/backlog-candidates/:id` accepts `title`, `description`, `status`, and `execution_role`. **Phase 6c PR-2 enforcement**: `execution_role` non-empty values MUST match a role in `roles.IsKnown` (catalog enforcement); empty string clears the column (NULL in DB). Unknown role returns 400. Case-sensitive (e.g. `"ui-scaffolder"`, not `"UI-Scaffolder"`). Every change to `execution_role` writes a row to `actor_audit` in the same transaction; the actor is derived from the request (session user or API-key id).
 - Candidate responses include `execution_role` (nullable string) and **Phase 6c PR-2** `execution_role_authoring` (object or null) — `{ actor_kind: "user"|"api_key"|"router"|"system"|"connector", actor_id?, rationale?, confidence? (router-only), set_at }`. Pre-Phase-6c rows have no audit history and surface `null`.
 - `POST /api/backlog-candidates/:id/apply` accepts JSON body `{ "execution_mode": "manual" | "role_dispatch", "execution_role"?: string }`. Missing body resolves to `"manual"`. **Phase 6c PR-2 contract change**: `mode=role_dispatch` REQUIRES `execution_role` to be present and in the catalog — empty or unknown returns 400. The chosen role becomes the `task.source` suffix (`role_dispatch:`), is persisted on the candidate row, and is audited. `mode=manual` ignores `execution_role`. The Phase 5 behaviour (silently producing a bare `"role_dispatch"` source from `candidate.execution_role`) is removed.

+# Phase 3B 計畫 — Planning 品質改進
+
+**Status**: draft v1.0 · 2026-04-27 · `[agent:feature-planner]`
+**前置條件**: Phase 6c（全部 5 PR）已合併；Phase 6d（role_dispatch_auto）dogfood 資料已累積足夠 router 信心樣本（目標：≥20 筆 suggest-role 操作）。
+**後置影響**: 完成後為 Phase 3A（Connector 可行性 spike）的規劃品質工作提供完整的 context-pack v2 基礎；並為 Phase 6d auto-dispatch 提供更可信的 confidence 訊號。
+
+---
+
+## 1. 問題陳述
+
+### 1.1 現有的三個品質缺口
+
+**Gap 1：Context pack 過於淺薄**
+
+`wire.PlanningContextV1`（見 `docs/context-strategy.md §7.1`）缺少以下欄位：
+
+| 欄位 | 現狀 | 影響 |
+|------|------|------|
+| `pack_id` | 缺失，以 `planning_run_id` 代替 | 無法跨 run 追蹤同一 context pack 的結果 |
+| `role` | 缺失（隱式 planner） | LLM 無法知道自己要扮演哪個角色 |
+| `intent_mode` | 缺失 | 永遠是隱式的 implement 模式 |
+| `task_scale` | 缺失（heuristic 在 adapter 端） | 無法在 context 層統一傳遞給不同 adapter |
+| `source_of_truth` | 缺失 | LLM 沒有指向 canonical doc 的指針 |
+| `approved_scope` | 缺失 | LLM 不知道允許觸碰哪些模組/檔案範圍 |
+
+後果：LLM 生成 candidate 時缺乏 grounding，容易偏離需求、建議不相干的任務、或誤解 intent。
+
+**Gap 2：Evidence 對使用者不可見**
+
+Candidate 生成後，使用者只看到 title + description，無法知道：
+- 哪些 open tasks 被納入 context？
+- 哪些 drift signals 被考慮？
+- 哪些 recent documents 有貢獻？
+- 是哪個 requirement 的哪個 planning run 的第幾號 candidate？
+
+後果：使用者無法評估 candidate 品質，也無法告訴系統「這個 candidate 是垃圾因為 context 根本錯了」。
+
+**Gap 3：沒有品質回饋迴路**
+
+目前 accept/reject candidate 只改狀態（`approved`/`rejected`），沒有：
+- 接受/拒絕的理由分類
+- 品質評分
+- 系統性的回饋積累
+
+後果：router 無法從使用者行為學習；planning quality 永遠停在初始水準，無法隨 dogfood 改進。
+
+### 1.2 為什麼要在 Phase 6d 之後做
+
+Phase 6d 的 `role_dispatch_auto` 要求 router confidence 可信，而 router confidence 的精準度直接依賴更完整的 context pack（Gap 1）。若 Phase 3B 先做好 context-pack v2，Phase 6d 的 auto-dispatch 準確率會有結構性提升。
+
+---
+
+## 2. End State
+
+完成所有 PR 後可驗證的行為：
+
+### 2.1 Context Pack v2（PR-1）
+
+1. `PlanningContextV2` 結構體新增：`PackID`（UUID）、`Role`、`IntentMode`、`TaskScale`（枚舉 small/medium/large）、`SourceOfTruth`（canonical doc 清單）
+2. `task_scale` heuristic 從 adapter 端提升到 planning 組裝層，統一推算後寫入 wire
+3. 每個 planning run 的 context pack 以 `pack_id` 做唯一標識，存入 `planning_runs.context_pack_id`
+4. 所有 adapter（Go built-in + future connector）都讀 v2 欄位；v1 欄位保持向後相容（過渡期 adapter 可忽略新欄位）
+
+### 2.2 Evidence Panel（PR-2）
+
+5. Candidate 卡片加入 "Evidence" 展開抽屜（預設折疊）
+6. 抽屜顯示：
+   - 納入 context 的 open tasks（title + status）
+   - 納入 context 的 drift signals（affected file + age）
+   - 納入 context 的 recent documents（doc name + staleness）
+   - `dropped_counts`（哪些來源因 byte cap 被截斷）
+7. Evidence 資料從 `planning_runs.context_pack_id` JOIN `planning_context_snapshots` 取得（需新增 snapshot 儲存，見 PR-1 backend）
+8. Candidate review panel（`CandidateReviewPanel`）與 planning workspace sidebar 均支援 evidence drawer
+
+### 2.3 品質回饋收集（PR-3）
+
+9. Candidate `approved`/`rejected` 操作增加可選的 `feedback_kind` 欄位：
+   - 接受時：`good_fit` / `modified` / `fallback`
+   - 拒絕時：`wrong_scope` / `too_broad` / `duplicate` / `low_quality` / `other`
+10. Candidate 卡片 approve/reject 按鈕加 optional feedback popover（可略過，不強制）
+11. Feedback 存入 `backlog_candidates.feedback_kind TEXT` + `backlog_candidates.feedback_note TEXT`（migration）
+12. `GET /api/planning-runs/:id` response 帶出 `quality_summary`：`{total, approved, rejected, acceptance_rate, feedback_distribution}`
+
+### 2.4 Planning Run 品質視圖（PR-4）
+
+13. Planning workspace 在所有 candidate 已 review 後顯示 run-level 品質摘要：
+    - 接受率 / 拒絕率
+    - 各 feedback_kind 分佈
+    - 哪些來源 context 被截斷（dropped_counts > 0 的警示）
+14. Dashboard planning 區塊加入 `avg_acceptance_rate`（過去 7 天 planning runs 均值）
+
+---
+
+## 3. PR 拆分與依賴
+
+```
+PR-1: Context Pack v2（backend）
+  → 新增 PlanningContextV2 結構體
+  → 提升 task_scale heuristic 到 planning 層
+  → 新增 planning_context_snapshots 表（migration）
+  → pack_id 寫入 planning_runs
+
+PR-2: Evidence Panel（frontend + thin backend）
+  ← 依賴 PR-1（需要 pack_id + snapshot 資料）
+  → GET /api/planning-runs/:id 帶 evidence 欄位
+  → CandidateReviewPanel evidence drawer
+
+PR-3: 品質回饋（backend + frontend）
+  ← 可與 PR-2 並行（無 hard dep）
+  → migration: backlog_candidates 加 feedback_kind / feedback_note
+  → PATCH /api/backlog-candidates/:id 接受 feedback 欄位
+  → Candidate 卡片 feedback popover
+
+PR-4: Planning Run 品質視圖（frontend + thin backend）
+  ← 依賴 PR-3（需要 feedback_distribution）
+  → quality_summary 計算 endpoint
+  → Dashboard avg_acceptance_rate
+  → Run-level summary panel
+```
+
+---
+
+## 4. 實作細節
+
+### 4.1 Context Pack v2 Schema（Go）
+
+```go
+// PlanningContextV2 — Context pack v2 contract
+// Backward-compatible: adapters that read V1 fields continue to work.
+type PlanningContextV2 struct {
+    SchemaVersion string            `json:"schema_version"` // "context.v2"
+    PackID        string            `json:"pack_id"`        // UUID, stable per planning run
+    Role          string            `json:"role"`           // e.g. "backend-architect"
+    IntentMode    IntentMode        `json:"intent_mode"`    // analyze | implement | review | document
+    TaskScale     TaskScale         `json:"task_scale"`     // small | medium | large
+    Limits        ContextLimits     `json:"limits"`
+    SourceOfTruth []SourceRef       `json:"source_of_truth"` // canonical doc pointers
+    Sources       ContextSources    `json:"sources"`
+    Meta          ContextMeta       `json:"meta"`
+}
+
+type SourceRef struct {
+    Name string `json:"name"` // e.g. "docs/operating-rules.md"
+    Path string `json:"path"`
+    Role string `json:"role"` // e.g. "safety-rules"
+}
+```
+
+### 4.2 Planning Context Snapshot 儲存
+
+新增 `planning_context_snapshots` 表：
+
+```sql
+CREATE TABLE planning_context_snapshots (
+    id           TEXT PRIMARY KEY,
+    pack_id      TEXT NOT NULL,
+    planning_run_id TEXT NOT NULL REFERENCES planning_runs(id),
+    schema_version TEXT NOT NULL DEFAULT 'context.v2',
+    snapshot     JSONB NOT NULL,
+    sources_bytes INTEGER NOT NULL DEFAULT 0,
+    dropped_counts JSONB,
+    created_at   TIMESTAMPTZ NOT NULL DEFAULT NOW()
+);
+CREATE INDEX idx_context_snapshots_run ON planning_context_snapshots(planning_run_id);
+```
+
+- Snapshot 只在 run 建立時寫一次，不可修改
+- `GET /api/planning-runs/:id` 增加 `context_snapshot` 欄位（opt-in，加 `?include=context` query param）
+- Evidence Panel 消費 `context_snapshot.sources` + `context_snapshot.dropped_counts`
+
+### 4.3 Candidate Feedback Migration
+
+```sql
+ALTER TABLE backlog_candidates
+    ADD COLUMN feedback_kind TEXT,
+    ADD COLUMN feedback_note TEXT;
+
+-- feedback_kind 允許值（server-side validation）：
+-- 接受: good_fit | modified | fallback
+-- 拒絕: wrong_scope | too_broad | duplicate | low_quality | other
+```
+
+### 4.4 TaskScale Heuristic 提升
+
+現有 adapter 的 task scale 推算邏輯（以 description 字數 + 關鍵字 heuristic）提升到
+`backend/internal/planning/scale/scale.go`，成為 planning 組裝層的公用函式：
+
+```go
+func EstimateTaskScale(title, description string, fileCount int) TaskScale
+```
+
+Adapter 端刪除重複邏輯，改呼叫 wire 中的 `TaskScale` 欄位。
+
+---
+
+## 5. 驗收標準

+
+## 6. 後續路徑（Phase 3B 完成後）
+
+```
+Phase 3B 完成
+    ↓
+Phase 3A: Connector 可行性 spike
+  - 驗證 trust boundary、pairing protocol、vendor compatibility（Copilot/ChatGPT）
+  - 使用 context-pack v2 作為 connector dispatch payload
+  - 目標：決定「connector 路線是否成立」，影響後續所有 connector 相關投資
+
+    ↓（如果 3A 可行）
+Phase 4（新）: Connector MVP 完整化
+  - Pairing session 完整流程
+  - Context pack v2 作為 connector dispatch 標準格式
+  - Result callback + execution result 可見性
+  - Task retry / cancel / regenerate 基礎 UX
+
+    ↓
+Phase 5（新）: Execution Mode UX Clarity
+  - 重新設計 execution mode picker（deterministic / server-provider / connector 三路徑）
+  - Connector developer onboarding 文件
+  - Task 執行結果 detail view
+
+    ↓（Phase 6d auto-dispatch 有足夠 feedback 資料後）
+Phase 6: Planning 自動化
+  - role_dispatch_auto mode（靠 Phase 3B feedback 資料驗證 router 信心）
+  - 多 connector 自動路由
+  - 非同步 job queuing（長任務）
+```
+
+> **注意**：Phase 3A spike 是「要不要繼續投資 connector 路線」的決策點。若 3A 結果是「不可行」，Phase 4 整個跳過，轉向加深 server-provider 路線。Phase 3B 的品質改進無論如何都有價值，與 connector 路線無耦合。
+
+---
+
+## 7. 範圍外（明確不做）
+
+- Context pack 的 `approved_scope` 欄位：需要 project-level approval surface，屬於 Phase 4+ 的功能，本 phase 不做
+- LLM-based context 品質評分（自動化評估 context pack 好不好）：Phase 6+ 的 ML 功能
+- Planning run 歷史對比視圖（比較兩次 run 的 candidate 品質）：nice to have，不是核心
+- Planning feedback 的 ML 訓練管道：資料積累階段先做，訓練屬於未來 SaaS 功能
+
+---
+
+## 8. 設計原則（per operating-rules.md）
+
+- **假設顯式化**（GLOBAL-001）：context-pack v2 的欄位設計假設所有 adapter 都遵從 v2 schema；若有 adapter 在過渡期仍讀 v1 欄位，必須在 PR 說明中列出相容性假設及失敗影響。
+- **Surgical changes**（GLOBAL-010）：PR-1 只動 planning context 相關程式碼，不順手清理其他模組的 dead code。
+- **Test-first for bugs**（GLOBAL-011）：若 context-pack 組裝邏輯發現 regression，先寫 failing test 再修。
+- **Documentation sync**（operating-rules.md）：`docs/context-strategy.md §7.1` 中的狀態表需在 PR-1 合併後同步更新，標記原本 `Planned` 的欄位為 `Live`。

Subject: [PATCH 4/5] feat(phase3a-spike): evidence panel + connector v2
 dispatch
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Phase 3A spike findings (docs/phase3a-spike-findings.md):
- Connector route viable for CLI tools (Claude, Codex, OpenCode); not viable
  for Copilot/ChatGPT (no CLI automation surface — use server_provider).
- Critical gap identified: Phase 3B backend had GET /context-snapshot but zero
  frontend; Phase 6d not ready yet (needs dogfood data).

Evidence Panel frontend (Phase 3B PR-2 completion):
- ContextSnapshot + ContextSnapshotSourceRef types added to types/index.ts.
- getContextSnapshot(runId) added to api/client.ts.
- PlanningRunContextDrawer: lazy-loaded collapsible drawer per run showing
  source counts, V2 envelope (role/intent/scale), byte budget, pack_id,
  source_of_truth files, and truncation warnings when dropped_counts > 0.
- PlanningRunList wires the drawer on all completed/failed runs.

Connector v2 dispatch upgrade (Gap 2):
- LocalConnectorClaimNextRunResponse gains optional planning_context_v2 field.
- saveContextSnapshot now returns *wire.PlanningContextV2 so ClaimNextRun can
  include v2 envelope in the response; connectors can read role/intent_mode/
  task_scale without a second round-trip.
- Backward-compatible: planning_context (v1) still present for older connectors.

+# Phase 3A — Connector Feasibility Spike: Findings
+
+**Status**: complete · 2026-04-27 · `[agent:feature-planner]`
+**Input**: Phase 3B shipped 2026-04-27; Phase 6c shipped 2026-04-27.
+**Question**: Is the connector route viable for broader vendor support (Copilot, ChatGPT)?
+           What are the highest-value improvements to make next?
+
+---
+
+## 1. Connector Route — Vendor Compatibility Matrix
+
+| Vendor | CLI automation surface | Viable via connector? | Recommendation |
+|--------|----------------------|----------------------|----------------|
+| Claude CLI (`claude`) | ✅ Stable, tested | ✅ **Primary path** | Current default; no change needed |
+| Codex CLI (`codex`) | ✅ Stable adapter exists | ✅ Viable | Already supported via same adapter contract |
+| OpenCode | ✅ stdin/stdout CLI | ✅ Viable with adapter | Adapter needs wrapping; low effort |
+| GitHub Copilot | ❌ `gh copilot` is explain/suggest only; no prompt-to-task CLI | ❌ Not viable | Use `server_provider` with OpenAI-compatible endpoint |
+| ChatGPT (OpenAI) | ❌ No official CLI | ❌ Not viable | Use `server_provider` mode (API key binding) |
+| VS Code Copilot | ❌ Extension only, no headless API | ❌ Not viable | Out of scope entirely |
+
+**Conclusion**: The connector route is a **CLI-tool route**, not a subscription-session route. Vendors
+without a prompt-in / structured-JSON-out CLI cannot be supported here. The `server_provider`
+mode (OpenAI-compatible API) is the correct path for ChatGPT and Copilot API.
+
+This finding closes the "should we invest in Copilot/ChatGPT connector?" question: **no**.
+Phase 4 (Connector MVP completeness) should focus on CLI-tool adapters only.
+
+---
+
+## 2. Gap Inventory (as of 2026-04-27)
+
+### Gap 1: Evidence Panel frontend missing (CRITICAL)
+
+**Impact**: Users cannot see what context the LLM received when evaluating candidate quality.
+Cannot answer "Was this bad candidate due to wrong context?" — the core Phase 3B PR-2 promise.
+
+**Backend state**: ✅ Complete
+- `GET /api/planning-runs/:id/context-snapshot` endpoint exists
+- `ContextSnapshotResponse` returns: pack_id, schema_version, role, intent_mode, task_scale,
+  source_of_truth[], sources_bytes, dropped_counts, open_task_count, document_count,
+  drift_count, agent_run_count, has_sync_run, available
+
+**Frontend state**: ❌ Not started
+- No `getContextSnapshot` in `api/client.ts`
+- No `ContextSnapshot` type in `types/index.ts`
+- No `PlanningRunContextDrawer` UI component
+- `PlanningRunList` shows quality summary row but no evidence drawer
+
+**Remediation**: Implement the Evidence Panel frontend (see §4.1).
+
+---
+
+### Gap 2: Connector dispatch still sends context-pack v1 (MEDIUM)
+
+**Impact**: Connectors don't receive role, intent_mode, task_scale, source_of_truth.
+The adapter prompt cannot be enriched with v2 envelope metadata.
+
+**State**: `ClaimNextRun` builds and saves a v2 snapshot but the `PlanningContextV1` wire payload
+is what gets sent to the adapter via stdin. The v2 struct is stored in the DB snapshot but
+**never forwarded** to the connector as the dispatch payload.
+
+**Remediation**: Upgrade `ClaimNextRun` to serialize v2 to stdin when the run has a pack_id
+and the snapshot was saved (i.e. migration 032 ran). Backward-compatible: old adapters that
+read `"sources"` / `"meta"` / `"limits"` see them at the same JSON path in v2.
+
+---
+
+### Gap 3: Phase 6d prerequisites not yet met
+
+**Trigger**: ≥5 real `role_dispatch` executions in dogfood + ≥1 week of Phase 6c running.
+**Current state**: Phase 6c shipped 2026-04-27. Zero dogfood data collected yet.
+**Action**: Dogfood Phase 6c for at least one week before opening Phase 6d planning.
+
+---
+
+### Gap 4: `approved_scope` field still missing from context-pack v2
+
+**Impact**: LLM has no explicit list of allowed modules/files → over-broad candidates.
+**Phase 3B plan §1.1 Gap 1** listed this as "out of scope for Phase 3B; Phase 4+".
+**Remediation**: Add `approved_scope []string` to `PlanningContextV2` when Phase 4 ships the
+approval surface. Not actionable now.
+
+---
+
+## 3. Phase 6d Readiness Checklist
+
+| Pre-condition | Current state | When met |
+|---|---|---|
+| Phase 6c fully shipped | ✅ 2026-04-27 | Done |
+| ≥5 real role_dispatch executions | ❌ 0 | After ~1 week dogfood |
+| ≥1 case: high-confidence but wrong | Unknown | After dogfood |
+| Phase 3B quality feedback loop | ✅ feedback_kind + quality_summary | Done |
+| Evidence Panel (visible quality signal) | ❌ Missing frontend | After Gap 1 fixed |
+| Evidence panel shows context truncation warnings | ❌ Missing frontend | After Gap 1 fixed |
+
+**Estimate**: Phase 6d planning can begin ≥ 2026-05-04 (1 week of dogfood),
+provided Gap 1 (Evidence Panel) is fixed before or alongside dogfood.
+
+---
+
+## 4. Recommended Roadmap
+
+### Immediate (this sprint)
+
+**4.1 Evidence Panel frontend** — closes Gap 1 (Phase 3B PR-2 completion)
+
+Components to build:
+- `ContextSnapshot` interface in `types/index.ts`
+- `getContextSnapshot(runId)` in `api/client.ts`
+- `PlanningRunContextDrawer` component (collapsible, lazy-loaded per run):
+  - Shows available=false gracefully ("Context data not available for older runs")
+  - Sources summary: N tasks · N documents · N drift signals · N agent runs · (sync run: yes/no)
+  - Context pack metadata: pack_id (truncated), schema_version, role, intent_mode, task_scale
+  - Byte budget: X KB used, source_of_truth files listed
+  - Truncation warnings: dropped_counts > 0 → warning chip per truncated source
+- Wire "Context" toggle into `PlanningRunList` on completed runs (lazy-loads on first open)
+
+**4.2 Connector v2 dispatch upgrade** — closes Gap 2 (Phase 3B PR-1 follow-up)
+
+- `ClaimNextRun` already saves v2 snapshot. Also pass v2 JSON to adapter stdin when
+  `context_pack_id` is non-empty (run has a v2 snapshot).
+- Adapter reads `schema_version` and can access role, intent_mode, task_scale.
+- Fully backward-compatible: v1 path still used when `context_pack_id` is empty.
+
+### Near-term (after 1 week dogfood)
+
+**4.3 Phase 6d planning** — triggered by dogfood data
+- `mode=role_dispatch_auto` + min_confidence threshold
+- `PhaseRouting` activity value for connector
+- `router_role_not_found` / `router_low_confidence` error kinds
+
+### Future (Phase 4 — Connector MVP completeness)
+
+- Connector task dispatch flow completeness (currently planning runs work; task dispatch is partial)
+- OpenCode adapter (CLI-based, same exec-json contract)
+- Lease renewal during long tasks (>30 min backend-architect runs)
+- Result callback visibility (execution result detail view)
+- Task retry / cancel / regenerate UX
+
+---
+
+## 5. Scope Decisions
+
+| Decision | Rationale |
+|---|---|
+| Copilot/ChatGPT connector path: **not viable** | No stable CLI automation surface; `server_provider` is correct for these vendors |
+| Phase 4 connector investment: **yes, for CLI tools** | Claude CLI proven; Codex/OpenCode viable; clear exec-json contract exists |
+| Phase 6d: **wait for dogfood** | router quality unvalidated; auto-apply on unvalidated router is premature |
+| `approved_scope`: **Phase 4+** | Requires project-level approval surface that doesn't exist yet |

Subject: [PATCH 5/5] fix(pr28-review): resolve critic, risk-reviewer, and
 Copilot review findings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes all blocking and should-fix issues found during the full review of
feat/phase6c-phase3b-accumulated before merge:

Hub (activity/hub.go):
- B1: remove close(c) from unsub() — eliminates send-on-closed-channel panic
  when Update() races with concurrent unsub (channels removed from map only)
- B2: add SubscribeWithCap(connectorID, userID) enforcing maxSSEPerUser=3,
  returns ErrSSECapExceeded; Stream handler now uses it (DECISIONS §(g))
- B3: add StartPurge(ctx) goroutine that evicts idle entries > 5 min old
  (DECISIONS §(g) "idle activities retained 5 min before purge")
- New tests: TestUpdate_ConcurrentUnsub_NoPanic, TestSubscribeWithCap_EnforcesLimit,
  TestStartPurge_EvictsIdleEntries

suggest.go:
- B4: sanitizeReasoning strips control chars and truncates to 1024 bytes per
  DECISIONS 2026-04-25 §(f); applied to reasoning and alternatives[].reason

planning_runs.go:
- C1(Copilot): SuggestRole always returns HTTP 200; LLM errors in error_kind/
  error_message body per API-008 advisory LLM contract

connector_activity.go:
- B2: Stream uses SubscribeWithCap → 503 on cap exceeded
- C4(Copilot): ListActive validates project exists via GetByID before listing

planning_run_store.go:
- C3(Copilot): log computeQualitySummary errors instead of silently dropping

Frontend:
- C2(Copilot): PlanningRunContextDrawer sets fetched.current only after
  successful load so transient errors can be retried on next open
- C5(Copilot): useConnectorActivity starts polling interval only in onerror
  fallback — no longer runs SSE + polling simultaneously (DECISIONS §(g))

Documentation:
- DECISIONS.md: add Phase 3B PR-3 entry for candidate feedback / quality summary
- docs/api-surface.md: document suggest-role endpoint contract and behavior
- docs/data-model.md: advance migration watermark to 034

Other:
- models/local_connector.go: PlanningContextV2 gets TODO comment citing Phase
  3A spike Gap 2 (field inert until connector protocol versioning resolves it)
- backend/cmd/server/main.go: call activityHub.StartPurge(ctx) at startup
- suggest_role_test.go: 4 new handler tests for suggest-role (503, 404,
  LLM-error→200, success→200) filling the MT3 coverage gap

+## 2026-04-27: Phase 3B PR-3 — candidate feedback fields + quality summary [agent:backend-architect]
+
+- **Context**: Phase 3B PR-3 adds optional operator feedback on evaluated backlog candidates (`feedback_kind`, `feedback_note`) and a derived `QualitySummary` on planning runs so the UI can show acceptance-rate and pending-review counts.
+- **Decision**: (1) Migration 034 adds `feedback_kind TEXT NOT NULL DEFAULT ''` and `feedback_note TEXT NOT NULL DEFAULT ''` to `backlog_candidates`. Existing rows get empty string — callers treat empty as "no feedback recorded". (2) Valid feedback kinds are an enumerated set in the store layer (`good_fit`, `poor_fit`, `needs_clarification`, `duplicate`); the store rejects unknown kinds with a typed error rather than silently storing garbage. (3) `QualitySummary` is computed on-the-fly in `PlanningRunStore.GetByID` via `computeQualitySummary`; it is NOT stored — re-computed on every fetch. Errors are non-fatal and logged. (4) `BacklogCandidateStore.Update` now accepts `FeedbackKind *string` and `FeedbackNote *string` nil-pointer semantics — nil means "leave unchanged", pointer to empty string means "clear". (5) Frontend `CandidateReviewPanel` adds an optional post-decision feedback row; acceptance-rate summary propagates to `ProjectOverviewTab`.
+- **Constraints introduced**: (a) `feedback_kind` must be one of the enumerated values or empty string; the store validates before writing. (b) `QualitySummary` is not persisted — removing candidates or re-running planning will change counts. (c) `Update` on an already-applied candidate is still rejected (pre-existing constraint). (d) Migration 034 `.down.sql` drops the two columns via standard `ALTER TABLE DROP COLUMN` (SQLite pre-3.35 note: down migrations are hand-invoked only — not auto-applied by the runner). Tests: `TestCandidateFeedback_*` in `backlog_candidate_feedback_test.go` pass.

 ## 2026-04-27: Phase 3B PR-1 — Context Pack v2 wire contract + planning_context_snapshots + pack_id on planning_runs [agent:backend-architect]

 Behavior:
 
+- `POST /api/backlog-candidates/:id/suggest-role` (Phase 6c PR-3): runs the dispatcher meta-prompt server-side (single-machine CLI assumption; see DECISIONS 2026-04-25 §(c)). **Always returns HTTP 200** — LLM failures are expressed as `{ error_kind, error_message }` in the body per API-008 (advisory LLM contract). On success returns `{ role_id, confidence, reasoning, alternatives: [{role_id, reason, score}] }`. `reasoning` and `alternatives[].reason` are sanitized to ≤1024 chars with control-char stripping. Does NOT write to `actor_audit`; the operator confirms by patching `execution_role`. Returns 503 when the CLI is not configured on the server host.
 - `GET /api/planning-runs/:id/context-snapshot` (Phase 3B PR-2): returns `{ available, pack_id, planning_run_id, schema_version, sources_bytes, dropped_counts, open_task_count, document_count, drift_count, agent_run_count, has_sync_run, role, intent_mode, task_scale, source_of_truth }`. When no snapshot exists (run predates Phase 3B or is not a local_connector run), returns `{ available: false }` with HTTP 200. Nonexistent run returns 404. Query param `?raw=1` returns the raw `PlanningContextV2` JSON blob as `data`. Snapshots are saved fire-and-forget on `ClaimNextRun` after a successful `BuildContextV1` call.
 - `PATCH /api/backlog-candidates/:id` accepts `title`, `description`, `status`, and `execution_role`. **Phase 6c PR-2 enforcement**: `execution_role` non-empty values MUST match a role in `roles.IsKnown` (catalog enforcement); empty string clears the column (NULL in DB). Unknown role returns 400. Case-sensitive (e.g. `"ui-scaffolder"`, not `"UI-Scaffolder"`). Every change to `execution_role` writes a row to `actor_audit` in the same transaction; the actor is derived from the request (session user or API-key id).
 - Candidate responses include `execution_role` (nullable string) and **Phase 6c PR-2** `execution_role_authoring` (object or null) — `{ actor_kind: "user"|"api_key"|"router"|"system"|"connector", actor_id?, rationale?, confidence? (router-only), set_at }`. Pre-Phase-6c rows have no audit history and surface `null`.
