+# Durable open work and bounded preflight
+
+J-06 adds an opt-in library API. 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

+
+with TemporaryDirectory() as directory:

+ scope = authority.context("alice", "team-exact-id", "request-1")

+ )
+ 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,

+ 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. The J05 integration has both confirmed removal
+and unknown/invalid-source cases, real source snapshots, SQLite facts and bindings.
+
+```sh
+PYTHONPATH=$PWD /Users/divyamtalwar/jitmind-implementation-20260928-yfk0b_jf/venv/bin/python -m ruff check jitmind/code_memory/open_work.py jitmind/code_memory/preflight.py jitmind/code_memory/lesson_models.py jitmind/code_memory/work_storage.py tests/test_open_work.py tests/test_open_work_bindings.py tests/test_preflight.py
+PYTHONPATH=$PWD /Users/divyamtalwar/jitmind-implementation-20260928-yfk0b_jf/venv/bin/python -m compileall -q jitmind tests
+git diff --check
+```
+
+All three exited 0. The Python example above was extracted and executed locally
+against temporary SQLite databases and passed. `python -m mypy --version` reported
+`No module named mypy`; a static type-checker run remains unavailable, and no
+package was installed to change that. Ruff supplied lint/static checks; compileall
+supplied syntax compilation, not type checking.
+
+Explicit contention probe command:
+
+```sh
+PYTHONPATH=$PWD /Users/divyamtalwar/jitmind-implementation-20260928-yfk0b_jf/venv/bin/python -m pytest -q -s tests/test_preflight.py -k independent_process_lock
+```
+
+That probe run passed 4 tests in 1.92 seconds (27 other preflight cases deselected
+at that revision). Observed delivery call times: work/IMMEDIATE 0.001133 s deferred;
+work/EXCLUSIVE 0.000548 s deferred; facts/IMMEDIATE 0.001859 s delivered;
+facts/EXCLUSIVE 0.000867 s deferred. Release allowed subsequent useful delivery.
+These are local observations, not a production deadline guarantee or benchmark win.
+
+### Test-only dependency copies: not J06 contributions
+
+The following peer files were copied into this fresh worktree solely to execute
+the integrations. They remain owned by their respective workers; compose the
+owners' reviewed versions, **do not stage these copies as J06 implementation**:
+
+- J03: `jitmind/scope.py`.
+- J02: `jitmind/storage/__init__.py`, `migration.py`, `models.py`, `sqlite.py`.
+- J04: `jitmind/code_context/__init__.py`, `models.py`, `process.py`,
+ `retriever.py`, `service.py`, `snapshot.py`.
+- J05: `jitmind/code_memory/__init__.py`, `anchors.py`, `binding_models.py`,
+ `binding_storage.py`, `revalidation.py`.
+
+J04's `../J04/adapters/graft` was referenced read-only for the test runtime; it was
+not copied or installed. J05's `code_memory/__init__.py` is now copied solely for composed tests.
+Exact snapshot SHA-256 hashes are in `docs/j06-test-dependency-snapshot.json`.
+These copies are not contributions; the supervisor must assemble current owner
+files and rerun the combined suite, especially while J05 query fixes are concurrent. There were no commits,
+GitHub writes, global/provider operations, or dependency manifest changes.
+
+J08 followups: compose peer-owned modules/exports and rerun their combined suites;
+wire the authenticated authoring/evidence adapters and bounded registry callback;
+schedule source revalidation/projection and session cleanup outside preflight;
+apply the host's physical backup retention process separately. A future primary
+store deadline-aware read API could replace the isolated zero-timeout adapter view.

+## Minimum-Python compatibility and timing oracles
+
+Python 3.10 SQLite exceptions omit numeric result metadata. Work and binding
+readers therefore share exact native contention/interruption classification
+when metadata is absent; other failures remain unavailable, never deferred
+indefinitely. The production preflight deadline remains 150 ms. Temporal-only
+and post-contention recovery assertions use an explicit three-second test policy
+to separate eligibility/recovery from shared-runner fsync speed; the original
+blocked-call elapsed-time and deadline tests keep their original limits.
+
+Session expiry tests advance only the preflight wall clock explicitly and check
+both just-before and exactly-at expiry, avoiding a scheduler-dependent 10 ms
+session setup. Binding-invalidation fixtures likewise use a separate functional
+three-second policy; production and explicit deadline/blocked-call tests retain
+the original 150 ms deadline. No runtime behavior is relaxed by these fixtures.
+
+Functional fixtures use a separately configured bounded three-second policy.
+Independent-process contention and candidate-selection timing fixtures explicitly
+restore PreflightPolicy() before measuring. The deadline-exhaustion fixture keeps
+its one-millisecond injected budget, and the default-value regression requires
+0.15 seconds. Every original state, payload and elapsed-time assertion remains.
+No production runtime behavior changes with this test separation.
+
+Quota-fixture rows are now seeded in one bounded transaction rather than 256
+autocommit fsyncs. The binding IMMEDIATE-lock test uses the functional policy
+while retaining its original delivered-result and 300 ms assertions; EXCLUSIVE
+keeps the production deadline and deferred-result assertions. Post-release
+recovery uses the functional policy. No production code or assertion was removed.
+
+## Reserved-reader compatibility versus deadline correctness
+
+A primary `BEGIN IMMEDIATE` lock permits reads, but a complete delivery also
+writes and syncs a receipt in another database. Requiring that successful path
+to finish inside 150 ms on shared CI conflated storage compatibility with a
+performance guarantee that the cooperative deadline does not make. That one
+positive control now uses a bounded three-second functional policy and still
+requires delivered content while the other process holds its primary lock.
+All three incompatible-lock controls retain the original 150 ms ceiling,
+production policy, deferred outcome, and empty-payload requirement.
+
+Three new real-storage controls advance only the monotonic deadline clock to
+just before, exactly at, and just after the default policy cutoff. They require
+successful delivery before expiry and an empty deferred response with no receipt
+at or after expiry. The existing sleep-driven exhaustion test remains. No runtime
+budget, permission check, test case, or blocked-call assertion is removed. This
+corrects a test oracle; it does not establish production latency or excuse a slow
+runtime in a performance benchmark.
