It needs no remote provider, vector index, graph, +model, hooks, CLI installation, or other product. Primary facts remain exclusively +owned by `SQLiteDurableStore` (J02); scope issuance remains owned by +`ScopeAuthority` (J03); code identity/revalidation remains owned by +`CodeMemoryService` (J05). Existing JSON fact/page formats are unchanged. + +## Public composition API + +Import from these modules directly (J05 owns `code_memory/__init__.py`): + +- `code_memory.work_storage`: `WorkDatabase(path)`, `WorkError`, `Conflict`, + `Deferred`, and the residual monotonic `Budget` passed to host adapters. +- `code_memory.open_work`: `OpenWorkService(database, authority, + is_admin=None, verify_evidence=None)`, immutable `Obligation`, `WorkPage`. + Methods: `create`, `transition`, `get`, `list`, `history`, `binding_locations`. +- `code_memory.lesson_models`: `LessonProjection(database, authority, facts, + can_author=None, can_retire=None, binding_authority=None)`, `FactAuthority`, + `DurableFactAuthority(store, authority)`, `DurableBindingAuthority(bindings, authority)`, + `ProposedAction(repo_id, file_path, symbol='', action='edit')`. + Methods: `import_observation`, `author_instruction`, + `project_binding_observation`, `candidates`, `retire_instruction`, `forget`. +- `code_memory.preflight`: `PreflightService(projection, policy=None, + approved_repo=None)`, `PreflightPolicy`, `PreflightResult`, `Session`. + Methods: `start_session`, `deliver`, `end_session`, `cleanup`. + +All scope arguments must be issued by the configured J03 authority. A manually +constructed context, even with identical claims/request ID, is rejected. Scope +checks run before disk/candidate work and before responses. Namespace and repo +IDs are exact opaque identifiers, never basenames or inferred remote identities. +Host initialization of `WorkDatabase` happens outside request handling. + +`approved_repo(scope, repo_id, relative_path, budget)` optionally checks a +host-configured registry such as J04. It must return exactly `True` to approve and +must use bounded, nonwaiting operations. No path is opened by preflight. Absolute, +dot, dot-dot, backslash, NUL, drive/URI, empty component, and percent-escape paths +are rejected before this callback. Action is one of `edit`, `write`, `read`, `test`; +symbol is structured lexical metadata, never parsed from prose or evidence. +A lesson on `Outer` applies to `Outer.inner`, but not `Outerish`. A host-authored +lesson with file `*` and empty symbol applies throughout that exact authorized +repository; it cannot grant cross-repository scope. Ordinary file paths match +exactly. Instructions rank before observations, then by file/symbol specificity, +confidence and stable ID. + +## Runnable local example + +Run the following Python with the composed J02/J03/J06 modules on `PYTHONPATH`. +It uses temporary SQLite databases and deterministic proposals, with no provider. +Host authentication, grants, authoring, and verification adapters must be configured +by the application; do not expose these administrative objects as model tools. + +```python +from pathlib import Path +from tempfile import TemporaryDirectory +from jitmind.scope import ScopeAuthority +from jitmind.storage import SQLiteDurableStore, IngestRequest, Proposal +from jitmind.code_memory.work_storage import WorkDatabase +from jitmind.code_memory.open_work import OpenWorkService +from jitmind.code_memory.lesson_models import ( + DurableFactAuthority, LessonProjection, ProposedAction, +) +from jitmind.code_memory.preflight import PreflightService + +with TemporaryDirectory() as directory: + root = Path(directory) + authority = ScopeAuthority() + authority.grant("alice", "team-exact-id", ["repo-exact-id"]) + scope = authority.context("alice", "team-exact-id", "request-1") + facts = SQLiteDurableStore(root / "facts.sqlite") + receipt = facts.ingest( + IngestRequest.create("team-exact-id", "fact-1", "Null inputs need a guard."), + lambda _: Proposal( + abstract="Null inputs need a guard.", header="Null handling", + decorated="Null inputs need a guard.", decision={"operation": "add"}, + ), + ) + database = WorkDatabase(root / "work.sqlite") + # A host verification registry, populated only after actual verification. + verified_runs = {"run-42": {"passed": True}} + def verify(scope, repo, refs, reason): + return bool(reason) and all( + ref in verified_runs and verified_runs[ref]["passed"] for ref in refs + ) + work = OpenWorkService(database, authority, verify_evidence=verify) + item = work.create( + scope, "repo-exact-id", summary="Finish null-input regression review", + expected_revision=0, idempotency_key="open-1", + decision_refs=(receipt.memory_id,), + ) + projection = LessonProjection(database, authority, + DurableFactAuthority(facts, authority)) + target = ProposedAction("repo-exact-id", "src/service.py", "process") + projection.import_observation( + scope, target, lesson_id="null-lesson", fact_id=receipt.memory_id, + version=1, source_revision=receipt.revision, + body="Null inputs need a guard.", source_verified=True, confidence=.95, + ) + preflight = PreflightService(projection) + session = preflight.start_session(scope, target.repo_id) + first = preflight.deliver(scope, session, target, delivery_key="edit-1") + assert first.state == "delivered" + assert preflight.deliver(scope, session, target).state == "nothing_relevant" + assert preflight.deliver(scope, session, target, + delivery_key="edit-1").replayed + done = work.transition( + scope, target.repo_id, item.id, status="resolved", expected_revision=1, + idempotency_key="resolve-1", reason="Verified against registered test run", + evidence_refs=("run-42",), + ) + assert done.status == "resolved" + preflight.end_session(scope, session) +``` + +The example registry is illustrative configuration, not a claim that a test run +named `run-42` occurred. In a host application, populate verification references +from the actual authenticated verification system. Neither reasons nor evidence +strings are executed, interpreted as commands, or used to grant permissions. + +## Work semantics and owner policy + +An obligation has a persistent UUID, namespace, exact repo, creator, owner, +revision, status, independent authored summary, optional binding/decision/evidence +reference IDs, and UTC created/updated/optional due timestamps. Reference arrays +are limited to 32 IDs; descriptions/reasons to 2,000 characters. These references +are opaque IDs: no primary fact body is copied or hydrated. Do not use a work +summary/reason as an archival copy of a forgettable fact body. + +Any repo-authorized principal can create self-owned work and read scoped work or +history. Assigning work to another owner and transitioning another owner's work +require the host-configured `is_admin(scope, repo)` predicate. Creator alone does +not confer owner privileges. The default denies admin actions. This is an explicit +application policy, not a role inferred from request metadata or text. + +Create requires `expected_revision=0`; transitions require the exact current +revision. Every create/transition has a caller-supplied `idempotency_key`, scoped by +namespace/repo/authenticated actor. A SHA-256 digest covers the canonical bounded +operation payload. Identical retries return the original immutable result across +restart, including an old revision after later transitions. Changed payloads under +the same key conflict. `BEGIN IMMEDIATE` serializes the compare-and-swap and writes +state, immutable transition history, and receipt in the same transaction. Competing +resolutions cannot both commit; a contender gets `Conflict` or transient `Deferred` +and may retry. Revisions reject booleans and out-of-range integers. + +`open`, `in_progress`, and `blocked` can transition to another nonterminal state +(except `open`) or to `resolved`/`cancelled`. Every transition requires a reason. +Resolution additionally requires nonempty evidence references accepted by the +configured verifier and records the actor. There is no default verifier. Text +saying “done”, elapsed due dates/TTL, missing code, and failed revalidation never +resolve work. Reopening `resolved` requires explicit `reopen=True`, status `open`, +a matching revision, authorization and a reason. `cancelled` is terminal; history +cannot silently disappear. Append-only history has SQL update/delete guards. + +`list(limit=50, after=0)` returns `WorkPage` and an opaque-in-practice integer +`next_cursor`; pass it as `after`. Limits are 1–100. Ordering uses an immutable +insertion sequence, not updated time or OFFSET. Transitions do not skip items in +pagination. History uses `after_revision`/`limit`. These are bounded live reads, +not a multi-page snapshot of concurrent new inserts. + +`binding_locations(scope, repo, work_id, bindings)` reads actual J05 +`get_current`; moves refresh only returned location. Missing, unknown, or confirmed +orphaned bindings fall back to the same authorized repo, never a different repo or +global scope. It does not mutate the obligation or J05's binding authority. This +method is for explicit work queries and is **not** part of preflight's hotpath. + +## Lessons, authority, and delivery + +A fact is a belief/observation; a trusted authored instruction is a distinct +host-authorized record; an obligation is unfinished work. `tier='law'` supplied to +`import_observation` stays an untrusted observation. Imports cannot overwrite an +instruction or change a record's kind. Only the separate `author_instruction` +operation can create instructions, and only when a configured authenticated +`can_author(scope, repo)` returns exactly `True`. Default: denied. Hosts must gate +that operation on authenticated authoring intent and never route arbitrary model +output, event ingest or imported metadata into it. A principal check alone is +insufficient if that principal's generic tools expose the authoring endpoint. +Preflight has no instruction/policy mutation path. Rank never grants permission. + +Authoring permission governs **future authoring**, including updates. Existing +repo-owner-approved policies are durable repository records: removing an author's +authoring permission or scope does not itself retire the repository's policy. +`can_author` must represent the repository owner's approval or delegated authority; +J06 cannot infer ownership from a principal name. Continued policy delivery to +another authorized reader is an explicit lifecycle choice, not a security claim. +Neither the author's departure nor policy retirement resolves unfinished work. + +Repository owners can explicitly retire one policy with +`projection.retire_instruction(scope, repo, lesson_id, expected_version=version)`. +The separately configured `can_retire(scope, repo)` must return exactly `True` and +must represent authenticated repository-owner/admin authority; it defaults to deny. +Retirement checks the version, increments it, blanks the projection body, and keeps +a terminal retirement marker. The ID cannot be re-authored; an intentionally new +policy needs a new ID. Saved receipts stop resolving the retired version. Primary +J02 deletion/forget also suppresses instructions and saved receipts immediately, +without waiting for a J06 forget event. Authoring revocation is therefore distinct +from primary instruction revocation and explicit owner retirement. + +Primary existence is **not** temporal applicability. `DurableFactAuthority` uses +actual J02 `get_entry` and `get_page` on every eligibility check. The fact, its +metadata and its backing page metadata must all be currently applicable. Recognized +timestamps are `t_created`, `created_at`, `t_observed`, `t_valid`, `t_invalid`, +`t_expired`, `expires_at`, `last_accessed`; timestamps must be full ISO timestamps +with seconds and explicit `Z` or `±HH:MM` offset (up to six fractional digits). +Naive/date-only strings, malformed offsets and reversed validity intervals fail +eligibility. Validity is `[t_valid, t_invalid)`; expiry/TTL end boundaries are +exclusive. `ttl_seconds` must be a finite nonnegative number (not a boolean or +string). TTL starts at metadata `t_created`/`created_at`, or the backing fact's +creation instant when metadata omits one. Absence of validity metadata adds no +extra limit; it never overrides a limit on another backing record. Authored +instructions inherit every backing limit and cannot grant unlimited validity. +Malformed temporal metadata yields `invalid_temporal_metadata`/`unavailable`; +corrupt records rejected within J02 yield sanitized authority/storage unavailability. +These checks run before candidates escape the projection and again before return +and receipt replay. A temporally expired but administratively active fact cannot +be passed to the accepted-forget cleanup API as if it had been deleted. + +Projection ingestion is a **host/background validation boundary**: do not pass +model-supplied `source_verified`, confidence, binding IDs/revisions or authoring +decisions through as trusted fields. `project_binding_observation` obtains J05's +actual current binding and persists its logical ID and revision as well as its +repo/path/qualified name/fact version. Changed/unknown/orphaned states remain +unverified. `author_instruction` and `import_observation` also accept optional +`binding_id` and `binding_revision` for host-established code-bound records. + +Bound records require `binding_authority.is_current(scope, repo, lesson, budget)`; +an absent adapter or non-boolean callback result returns explicit +`binding_authority_unavailable`, never a positive result. The included `DurableBindingAuthority(bindings, authority)` reads +J05 schema-v2 heads/history, terminal fact markers and recorded source snapshot/ +generation with zero SQLite busy wait and a residual progress handler. It checks +the projected revision against the current J05 head and requires verified state, +no review flag, matching fact, and matching recorded source. This is a scoped, +read-only adapter, not a second binding writer or revalidation service. It requires +an existing schema-v2 J05 database (let J05 initialize/migrate it outside preflight) +and fails closed on an unavailable/unknown schema. A future J05 schema should +supply/update this bounded adapter. No graph rebuild, +source file read, parser or model is invoked by preflight. + +Checks run before candidate emission, before rendering/receipt commit, and after +commit before response. Once J05 records changed/unknown/retracted binding state, +old bound text is suppressed even with intentionally delayed J06 projection. +Republish with a higher material lesson version after a newly verified binding +revision. A new binding revision is conservatively invalidating even if J05 found +the body unchanged. This does **not** claim atomicity with live filesystem changes +J05 has not observed, or a global transaction across the separate databases. Old +projection payloads without the additive binding fields still load as unbound +observations for compatibility; hosts must retire/reproject legacy code-bound rows +before exposing them under the new bound-record guarantee. J06 cannot reconstruct +missing binding identity from arbitrary lesson text. + +The pipeline applies namespace/repo/file/lexical-symbol/action scope, kind, +confidence, projected validity, verification and retirement filters **before** +LIMIT. It orders authored policies first and then specificity/confidence/ID. It +reads at most 21 IDs (the last is a tail sentinel), hydrates/checks at most 20 bodies, +and renders at most two. SQLite scanning/sorting is interrupted by the residual +progress handler; this bounds execution by a best-effort deadline, not a constant +number of internal SQLite steps. Current primary/binding authority can still reject +all 20 while a tail exists; already-delivered candidates can also occupy a window. +Such empty selection returns `deferred/selection_incomplete`, with +`selection_complete=False`, rather than claiming nothing relevant. Delivered +results also disclose an unexamined tail. `candidate_count` reports examined +projection bodies on completed selection paths; failures before completing selection +report zero and unavailable/deferred results do not claim selection completeness. +No unbounded fallback or raw fallback occurs, even when ranking returns empty. +Default hypotheses, expired lessons, unvalidated sources and confidence below .8 +are silent; explicit policies can admit hypotheses/unvalidated observations with +labels, but cannot bypass current bound-record authority. + +Every body is quoted and labeled; imported observations never say “instruction”. +The renderer bounds input, strips controls, neutralizes delimiters and redacts +common credential assignments, URL credentials, authorization tokens and known +key-shaped literals. This is limited redaction, **not** a universal secret guarantee +or an injection-proofing claim. Evidence strings are never rendered or interpreted. +No parsed prose influences tool authorization, and exception text is not logged. + +A session is a process-issued, immutable capability owned by principal/namespace/ +repo/current authorization version, with at most 24-hour expiry. Ownership and +scope are checked **before any disk read** and again before return. Request IDs +are not authentication. Sessions are newly issued after restart. Delivery rows have +SQL uniqueness over session/code identity/lesson/material version/policy revision. +A new material version can resurface, and callers should increment policy revision +when changing policy. At most 256 receipts/512 lessons per session, 1024 live +sessions; quota exhaustion returns `deferred`. `end_session` cascades receipt and +dedup deletion; `cleanup(scope)` deletes expired sessions, and session creation +also runs cleanup. Schedule host cleanup if no new sessions arrive. If cleanup is +contended, retry; no hotpath growth exceeds the quotas. + +Pass a stable `delivery_key` to deliberately replay a receipt after an uncertain +response. The digest binds target and policy; a changed request conflicts. Receipts +store IDs/versions, **not payload text**. Replay rechecks projection version, +current primary temporal authority, current binding authority, session and scope. A changed/forgotten lesson is not +replayed. Concurrent callers produce one logical delivery per uniqueness key; +losers return silence or `deferred` rather than waiting. A committed receipt can +outlive a response suppressed by a deadline/revocation race; replay the same +explicit delivery key after recovery. Without that key, the session may regard the +lesson as delivered even if the caller never received it. + +Result states are `delivered`, `nothing_relevant` (normal silence), `deferred` +(contention/deadline/quota), and `unavailable` (safe generic authority/storage +failure). Invalid scopes/sessions raise generic J03 `ScopeDenied`; malformed +metadata raises `WorkError`; revision/idempotency conflicts raise `Conflict`. +Results expose safe reason codes, lesson IDs, receipt ID, replay flag, payload +bytes and `token_count_method='utf8_byte_upper_bound'`. The default 600-token target +is enforced conservatively as at most 600 UTF-8 bytes including all wrappers, +which upper-bounds UTF-8 byte-tokenizer counts without downloading a tokenizer. +The separate byte cap defaults to 2400 and can be stricter. The measured count is +bytes, not a claim of exact tokens for an arbitrary model's tokenizer. + +## Deadlines and contention + +The default deadline is 150 ms, finite and positive, measured with a monotonic +clock. SQLite connections have **zero busy wait**. The dedup write thus stays +within `min(residual, 100 ms)` rather than consuming a fresh timeout on each +statement. SQLite progress handlers interrupt longer projection queries; residual +checks surround selection, authority reads, rendering, transaction and return. +`DurableFactAuthority` calls true J02 `get_entry(namespace, id)` and `get_page` through a shallow, +operation-local configuration view with zero busy timeout; it never changes the +shared primary store's timeout or reinitializes its schema in preflight. + +No graph/model/parser/source-file reads or full-graph ingestion occur here. +External authority/registry callbacks must implement bounded nonwaiting I/O. Python +cannot preempt an arbitrary callback or guarantee OS scheduling, filesystem-open, +fsync, or hardware latency; this is a best-effort synchronous deadline, not a hard +real-time guarantee. Tests hold independent-process RESERVED and EXCLUSIVE SQLite +locks. Work DB contention and primary EXCLUSIVE contention return visible +`deferred`; a primary RESERVED write lock permits a normal current read in DELETE +mode. The local probe timings are reported in the worker handoff, not generalized +to production latency. + +## Forget, schema, migration and retention + +An accepted primary forget is immediately authoritative. Every projection query +checks `FactAuthority.is_active(scope, fact_id, budget)`, and every selected payload +is checked again after rendering and just before final return. No body cache exists. +The real adapter uses J02's `get_entry` and `get_page`, not outbox/projection status. A namespace +forget does not resolve obligations. Binding history and work references remain +content-free IDs; independently authored work summaries remain work records. + +After J02 accepts forget, call `LessonProjection.forget(scope, fact_id, + tombstone_revision=event_revision)`. It refuses an active primary fact, removes +lesson bodies (already body-free retirement markers persist), retains the highest per-fact tombstone revision, and ignores upserts +at or below that revision. An inactive primary fact also rejects upserts of any +revision, so late/duplicate old events cannot resurrect it. Projection cleanup can +return `projection_purge_deferred`; primary checks still hide the body. The report +explicitly states `historical_ids_and_backups_may_remain`. + +The metadata database has application ID `0x4A36574B`, user version 1, and tables: +`work`, `history`, `work_receipts`, `lessons`, `tombstones`, `sessions`, `deliveries`, +`delivery_receipts`. Startup accepts only an empty new DB or the exact known schema; +it rejects foreign/future/mismatched schemas. No legacy JSON data is rewritten. +There is no v0 adoption or silent schema migration. Future migrations must be +explicit, transactional, versioned, and preserve receipts, history and tombstone +watermarks. Do not point this API at the primary fact DB or a J05 binding DB. + +Use a trusted local path and local single-host filesystem. DELETE journaling, +FULL synchronization, foreign keys, bounded requests and transactions are the +defaults. Back up the metadata DB with SQLite's backup facility during host +maintenance, and restore the DB as a unit; copying a live file is not the API. +Work histories/idempotency receipts and tombstone watermarks are retained for +correctness; delivery rows expire with sessions. No automatic obligation purge or +receipt TTL can silently invalidate historical idempotency. Current-row deletion +does not securely overwrite SQLite free pages, historical backups or external +copies. Physical backup purge requires the host's retention process and is not +promised by visibility hiding. + +## Verification and integration notes for J08 + +Tests use actual temporary SQLite databases and J03-issued contexts. They cover +J16–J20 and J31: CAS/owner/admin/reopen/idempotency, independent-process contention, +material-version/session dedup, max-two rendering and full wrapper budgets, +malicious imported law, authored positive control, no-match control, empty ranking, +repo/session/namespace isolation, revocation, current-authority forget with pending +outbox, delayed purge, backup retention, and actual J05 binding movement/removal. + +The binding integration requires J04's separately provisioned local Node adapter: +set `JITMIND_TEST_GRAFT_ADAPTER` (and optionally `JITMIND_TEST_NODE`). That dependency +is used by the integration test/background binding workflow, never by preflight. +No packages were installed and no dependency manifest was changed for J06. + +Latest verification and remaining limits: [J56 revision report](j06-review-fixes.md). + +### Original worker verification record (superseded by J56 revision report) + +Final repository test command, run in the J06 worktree: + +```sh +JITMIND_TEST_GRAFT_ADAPTER=$PWD/../J04/adapters/graft PYTHONPATH=$PWD /Users/divyamtalwar/jitmind-implementation-20260928-yfk0b_jf/venv/bin/python -m pytest -q tests +``` + +Outcome: **81 passed, 3 expected optional-provider warnings, 20.19 seconds**. +This is the original 38-test suite plus 43 J06 cases, not the uncomposed peer +workers' entire new test suites.
