+# ADR 0362: Version product UI translations in PostgreSQL
+
+- Status: Proposed
+- Date: 2026-09-03
+- Owners: LineageWeave product read model / Customer Master UI composition
+- Related: #922, `migrations/0246_ui_translation_ledger.sql`, `backend/app/translation_ledger.py`
+
+## Problem
+
+LineageWeave currently ships product UI copy in the frontend bundle and admits only `en`, `ko`, `zh`, `ja`, and `vi` as persisted member locale preferences. That makes a deploy artifact the mutable source of product copy, leaves the required `es`, `de`, and `fr` buyer paths unsupported, and provides no immutable screen-version identity for evidence, rollback, or cache correctness.
+
+This ledger is strictly for LineageWeave-owned product UI copy. Ontology labels, concept names, and semantic truth remain with their canonical owners and must enter LineageWeave only through released contracts or ACLs.
+
+## Constraints
+
+- The product locale contract is exactly `ko`, `en`, `ja`, `zh`, `vi`, `es`, `de`, and `fr` for this increment.
+- Locale identifiers are language tags interpreted according to BCP 47 / RFC 5646; adding region or script distinctions requires an explicit product decision and a new compatible version of the contract.
+- PostgreSQL is authoritative. Valkey is an optional read cache and must not become a second source of truth.
+- A published screen version is immutable and complete for every required screen key in all eight locales.
+- Reads do not silently fall back to another locale. Missing or blank requested-locale copy is an error.
+- Cache identity must include product, screen, immutable resource version, and locale.
+- Publication must serialize with child key/text mutation so a complete resource cannot become incomplete after the publication check.
+- The design must stay independent from ontology-label persistence and from another CWL product's domain tables.
+
+## Alternatives considered
+
+### Keep translations in the SPA bundle
+
+Rejected. It couples copy lifecycle to frontend deployment, cannot provide an immutable database identity for a screen/version/locale projection, and perpetuates the five-locale gap.
+
+### Store product copy with ontology labels
+
+Rejected. Product UI copy and semantic concept labels have different ownership, versioning, review, and rollback semantics. Sharing their source of truth would violate the canonical-owner boundary and make ordinary copy changes semantic changes.
+
+### Use a mutable key/value translation table
+
+Rejected. In-place mutation destroys the evidence needed to reproduce what a buyer saw and makes cache invalidation dependent on timing rather than identity.
+
+### Version product-owned screen resources in PostgreSQL
+
+Selected. It gives the read model a stable aggregate identity, keeps copy ownership local to LineageWeave, and permits exact-version caching without duplicating semantic truth.
+
+## Decision
+
+`ui_translation_resource` is the aggregate root identified by `(product_key, screen_key, resource_version)`. A resource starts as `draft`; publication is a one-way transition. `ui_translation_key` declares the screen's required keys. `ui_translation_text` supplies one nonblank value for each `(resource_id, translation_key, locale)`.
+
+The schema remains in 3NF: resource version metadata, required keys, and localized values are separate relations. The database enforces unique resource versions and unique localized values. Publication rejects an empty key set or any missing member of the required key × eight-locale matrix. Once published, the root and all child rows are immutable.
+
+Child insert/update/delete obtains a `FOR UPDATE` lock on the parent resource. Publication already locks the resource row through its update. Therefore publication and child mutation are serialized: either the child change commits before the completeness scan, or it observes the published state and is rejected. Child rows may not be re-parented between resources.
+
+`read_translation_screen` returns a complete `TranslationScreen` projection. Latest-version reads resolve PostgreSQL first so a stale cache alias cannot hide a newer publication. Explicit immutable versions may be served by Valkey under `ui-translation:{product}:{screen}:v{resource_version}:{locale}`. Malformed, unavailable, or identity-mismatched cache entries are misses and fall back to PostgreSQL. An unavailable cache never makes a valid PostgreSQL translation unavailable.
+
+The existing `user_account.preferred_locale` constraint expands to the same eight language tags. API request validation and frontend consumption must be cut over to the same contract before #922 can close; the database/read-model foundation alone is not buyer-visible completion.
+
+## DDD mapping
+
+- Subdomain: product composition / presentation read model.
+- Bounded context: LineageWeave product read model.
+- Aggregate: versioned UI translation resource.
+- Entity/value identity: required screen key; locale-tagged translated text.
+- Repository boundary: PostgreSQL query in `backend.app.translation_ledger`; Valkey is a cache adapter, not a repository of record.
+- Invariants: exact eight-locale completeness at publication, immutable published versions, no cross-resource child move, no locale fallback, exact cache identity.
+- ACL: ontology labels remain external semantic truth and are not stored in these tables.
+
+## Recovery and migration
+
+Migration 0246 is additive for translation resources and only broadens the existing member locale constraint. While the old SPA bundle is still the consumer, deploying the migration is backward-compatible. If application rollout fails before consumers switch, roll back the application path while retaining the additive schema and any draft resources.
+
+Published translation data is not destructively down-migrated. A bad published resource is corrected by publishing a new `resource_version` and moving consumers to that version/latest publication. Once customer copy exists, rollback means application/read routing to a previously admitted version, not dropping tables or rewriting published rows.
+
+## Evidence
+
+- RED `092d32137fd6764a4f1fc7a53125a15318814292`: executable contract required the eight locales, normalized schema, exact cache identity, and fail-closed completeness before implementation existed.
+- RED `370f83a28f4a0fdeb000ea5a259d66c415c1a746`: review found that child mutation could race publication; the contract required parent-row serialization.
+- Repair `bb61753db7a483c766690e830700637694135208`: child mutation now locks the parent resource with `FOR UPDATE`, preserving completeness across concurrent publication.
+
+These commits are branch evidence only. This ADR remains Proposed until the exact protected-line implementation and dependent API/frontend cutover are verified.

 `ui_translation_resource` is the aggregate root identified by `(product_key, screen_key, resource_version)`.

 Child insert/update/delete obtains a `FOR UPDATE` lock on the parent resource. Publication already locks the resource row through its update. Therefore publication and child mutation are serialized: either the child change commits before the completeness scan, or it observes the published state and is rejected.

 `ui_translation_resource` is the aggregate root identified by `(product_key, screen_key, resource_version)`. A resource starts as `draft`; publication is a one-way transition. `ui_translation_key` declares the screen's required keys. `ui_translation_text` supplies one nonblank value for each `(resource_id, translation_key, locale)`.
 
-The schema remains in 3NF: resource version metadata, required keys, and localized values are separate relations. The database enforces unique resource versions and unique localized values. `product_key` and `screen_key` must already equal their `btrim(...)` values, matching the application boundary that canonicalizes caller input before lookup/cache identity construction. Publication rejects an empty key set or any missing member of the required key × eight-locale matrix. On the draft-to-published transition the trigger assigns `published_at := now()` unconditionally, so the immutable publication receipt comes from PostgreSQL rather than caller input. Once published, the root and all child rows are immutable.

 Child insert/update/delete obtains a `FOR UPDATE` lock on the parent resource. Publication already locks the resource row through its update.

-`ui_translation_resource` is the aggregate root identified by `(product_key, screen_key, resource_version)`. A resource starts as `draft`; publication is a one-way transition. `ui_translation_key` declares the screen's required keys. `ui_translation_text` supplies one nonblank value for each `(resource_id, translation_key, locale)`.
+`ui_translation_resource` is the aggregate root identified by `(product_key, screen_key, resource_version)`. A resource starts as `draft`; publication is a one-way transition. The aggregate identity is fixed at INSERT and cannot be changed while draft or as part of publication. `ui_translation_key` declares the screen's required keys. `ui_translation_text` supplies one nonblank value for each `(resource_id, translation_key, locale)`.
 
 The schema remains in 3NF: resource version metadata, required keys, and localized values are separate relations. The database enforces unique resource versions and unique localized values. `product_key` and `screen_key` must already equal their `btrim(...)` values, matching the application boundary that rejects noncanonical caller spellings before lookup/cache identity construction. Publication rejects an empty key set or any missing member of the required key × eight-locale matrix. On the draft-to-published transition the trigger assigns `published_at := statement_timestamp()` unconditionally, so the immutable receipt is produced by the publication statement rather than caller input or transaction-start time. Once published, the root and all child rows are immutable.

 ## Recovery and migration
 
 Migration 0246 is additive for translation resources and only broadens the existing member locale constraint. While the old SPA bundle is still the consumer, deploying the migration is backward-compatible. If application rollout fails before consumers switch, roll back the application path while retaining the additive schema and any draft resources.

-`ui_translation_resource` is the aggregate root identified by `(product_key, screen_key, resource_version)`. A resource starts as `draft`; publication is a one-way transition.

The database enforces unique resource versions and unique localized values. `product_key`, `screen_key`, and each required `translation_key` must already equal their `btrim(...)` values and must not match leading/trailing `\s` in PostgreSQL's regular-expression engine; identifier edge whitespace is rejected, not normalized. This explicit regex guard is required because default `btrim` removes only plain spaces. Publication rejects an empty key set or any missing member of the required key × eight-locale matrix. On the draft-to-published transition the trigger assigns `published_at := statement_timestamp()` unconditionally, so the immutable receipt is produced by the publication statement rather than caller input or transaction-start time. Once published, the root and all child rows are immutable.

 The existing `user_account.preferred_locale` constraint expands to the same eight language tags. API request validation and frontend consumption must be cut over to the same contract before #922 can close; the database/read-model foundation alone is not buyer-visible completion.

 - Whitespace-only copy repair `9b42748e9b296a88ed4bc01664945c23c65a720a`: `ui_translation_text` now rejects all-whitespace values while preserving nonblank presentation text exactly.
 - Value-object RED `9f04f097fab7a9da0d9086b29776b01b42f082eb`: both PostgreSQL and exact-version cache-hit paths must reject mutation of the returned translation mapping.
 - Value-object repair `035fbc862caccbd74428021314f534f1b4bce35d`: both construction paths detach translations behind `MappingProxyType`; cache serialization materializes a plain dictionary only at the adapter boundary.
+- Cache-authority RED `ea95121a3bf93c606e2214161941d23bbed53794`: a complete exact-version cache payload with correct identity and key coverage but altered copy must fall back to PostgreSQL.
+- Cache-authority repair `34955985965bef045614cb445b65853760991fb6`: the explicit-version admission query now returns PostgreSQL SHA-256 evidence for each requested-locale value and cached copy must reproduce every digest before return.
+- Read-model verification alignment `1e9d6f984e108f1505e33eb94c56a0b123ace693`: cache-hit fixtures carry the same authoritative digests, while the poisoned complete payload requires a second PostgreSQL acquisition and authoritative copy.
+- Real-PostgreSQL verification `dc5e374bb2e309bd45086b4d928c7cc9a4a0aa22`: migration-backed PostgreSQL executes the exact admission query and proves its built-in UTF-8 SHA-256 output matches the application digest.
 
 These commits are branch evidence only. This ADR remains Proposed until the exact protected-line implementation and dependent API/frontend cutover are verified.

 - `product_key` and `screen_key` are canonical identity segments: blank, colon-bearing, or leading/trailing-whitespace forms are rejected consistently by PostgreSQL and the application boundary.
 - Each required `translation_key` is also a canonical identifier: blank or leading/trailing-whitespace forms are rejected by PostgreSQL rather than becoming visually ambiguous distinct keys inside one immutable screen version.
-- PostgreSQL's one-argument `btrim` removes a plain space by default; it is not sufficient to implement the application boundary's broader edge-whitespace rejection. The migration therefore retains the trimmed-space check and separately rejects leading/trailing PostgreSQL regular-expression whitespace for identifiers, and rejects all-whitespace translated copy without trimming valid copy.
+- Whitespace admission is a product contract, not a database-locale side effect. The explicit repertoire is U+0009–U+000D, U+001C–U+001F, U+0020, U+0085, U+00A0, U+1680, U+2000–U+200A, U+2028–U+2029, U+202F, U+205F, and U+3000. The Python boundary and PostgreSQL constraints use this same fixed repertoire.
+- PostgreSQL POSIX character classes and shorthands such as `\s` are not used for this invariant because non-ASCII class membership can depend on collation/`LC_CTYPE`; a valid `C`-locale database must reject the same identity padding and blank copy as the application.
 - Cache identity must include product, screen, immutable resource version, and locale.
 - An explicit-version cache hit is admissible only after PostgreSQL confirms the published resource, its exact required screen-key set, and SHA-256 evidence for each requested-locale value. A structurally complete cache payload whose copy does not match that evidence is a miss.
 - PostgreSQL pool leases must not be held while awaiting optional Valkey I/O. Published resource/key/value identity is immutable, so cache admission can occur after releasing the integrity-evidence query connection and PostgreSQL can be reacquired only on a cache miss or failure.

 ## Decision
 
-`ui_translation_resource` is the aggregate root identified by `(product_key, screen_key, resource_version)`. A resource starts as `draft`; publication is a one-way transition. The aggregate identity is fixed at INSERT and cannot be changed while draft or as part of publication. `ui_translation_key` declares the screen's required keys. `ui_translation_text` supplies one value for each `(resource_id, translation_key, locale)` and rejects values made entirely of PostgreSQL regular-expression whitespace; valid text is stored byte-for-byte, including intentional surrounding whitespace.

Valid presentation text is stored byte-for-byte, including intentional surrounding whitespace, but `btrim(text, explicit_whitespace_characters) <> ''` requires at least one character outside the contracted whitespace repertoire.
 
-The schema remains in 3NF: resource version metadata, required keys, and localized values are separate relations. The database enforces unique resource versions and unique localized values. `product_key`, `screen_key`, and each required `translation_key` must already equal their `btrim(...)` values and must not match leading/trailing `\s` in PostgreSQL's regular-expression engine; identifier edge whitespace is rejected, not normalized. This explicit regex guard is required because default `btrim` removes only plain spaces. Publication rejects an empty key set or any missing member of the required key × eight-locale matrix, and every admitted text row must contain at least one non-whitespace character so a published immutable version cannot become unreadable by construction. On the draft-to-published transition the trigger assigns `published_at := statement_timestamp()` unconditionally, so the immutable receipt is produced by the publication statement rather than caller input or transaction-start time. Once published, the root and all child rows are immutable.
+The schema remains in 3NF: resource version metadata, required keys, and localized values are separate relations. The database enforces unique resource versions and unique localized values. `product_key`, `screen_key`, and each required `translation_key` must be nonempty and must equal `btrim(value, explicit_whitespace_characters)`; identifier edge whitespace is rejected, not normalized. The application uses the same explicit character repertoire for its admission and blank-copy checks. This avoids dependence on the Python runtime's evolving Unicode tables and on PostgreSQL collation/`LC_CTYPE`. Publication rejects an empty key set or any missing member of the required key × eight-locale matrix, and every admitted text row must contain at least one non-whitespace character so a published immutable version cannot become unreadable by construction.

Once published, the root and all child rows are immutable.
 
 Child insert/update/delete obtains a `FOR UPDATE` lock on the parent resource. Publication already locks the resource row through its update. Therefore publication and child mutation are serialized: either the child change commits before the completeness scan, or it observes the published state and is rejected. Child rows may not be re-parented between resources.
 
-`read_translation_screen` returns a complete `TranslationScreen` projection whose translation mapping is detached and read-only, so application code cannot mutate product copy while retaining the same immutable published identity. Latest-version reads resolve the complete projection from PostgreSQL so a stale cache alias cannot hide a newer publication. For an explicit immutable version, PostgreSQL first resolves the published resource's ordered required-key set plus `encode(sha256(convert_to(translated_text, 'UTF8')), 'hex')` evidence for the requested locale and then releases that pool lease. Valkey may serve `ui-translation:{product}:{screen}:v{resource_version}:{locale}` only when the cached key set exactly equals the authoritative set, all values are nonblank, and every cached UTF-8 value reproduces its PostgreSQL SHA-256 digest. Missing/malformed digest evidence or malformed, unavailable, identity-mismatched, partial, extra-key, or value-mismatched cache entries are misses. On a miss, the reader reacquires PostgreSQL for the localized text projection. This avoids transferring full localized copy on a valid cache hit while keeping PostgreSQL, rather than Valkey, authoritative for both shape and value integrity. PostgreSQL's built-in SHA-256/`convert_to` functions make the evidence independent of `pgcrypto`. An unavailable cache never makes a valid PostgreSQL translation unavailable. Cache serialization converts the read-only mapping to a plain JSON object only inside the cache adapter.

 - Cache-authority repair `34955985965bef045614cb445b65853760991fb6`: the explicit-version admission query now returns PostgreSQL SHA-256 evidence for each requested-locale value and cached copy must reproduce every digest before return.
 - Read-model verification alignment `1e9d6f984e108f1505e33eb94c56a0b123ace693`: cache-hit fixtures carry the same authoritative digests, while the poisoned complete payload requires a second PostgreSQL acquisition and authoritative copy.
 - Real-PostgreSQL verification `dc5e374bb2e309bd45086b4d928c7cc9a4a0aa22`: migration-backed PostgreSQL executes the exact admission query and proves its built-in UTF-8 SHA-256 output matches the application digest.
+- Collation-independence RED `888a6f1a0ad7634bc2e29fa6102bdbec1f2a9723`: hosted/static evidence requires one explicit whitespace repertoire and the real-PostgreSQL scenario creates a UTF-8 `C`-locale database where NBSP/U+3000 identity padding and all-whitespace copy must still fail.
+- Database repair `2b921e0c6aee39903d97191864ccda3b954c3caf`: migration 0246 replaces locale-sensitive POSIX classes with exact `btrim(text, characters)` code points.
+- Application repair `f0ad89dd438e8369a676ee8bac42e2a96b9fe4d5`: identity, completeness, and cache admission use the same fixed `_UI_WHITESPACE` repertoire rather than an implicit runtime Unicode table.
+- Hosted verification alignment `e33ad222e2b7b162e872ecb6919401d0291ed032`: ordinary contract tests cover NBSP/U+3000 admission and require the explicit migration representation while rejecting the superseded regex contract.

+> `2e83785c70fb0fc9fc7dfb81c9c81403983a3de9` supplies the ADR 0362 versioned
+> translation-ledger foundation and passes its focused 31-test local contract,
+> but is still a draft with queued hosted checks and no independent approval.
+> It does not yet provide the authenticated PostgreSQL API and rendered
+> desktop/mobile evidence required to call the buyer flow complete, so the gap
+> remains **partially implemented / runtime unverified**. PR #925 at

+> check is transferred to these heads.

+> The next commit on this branch, `ceed87e0a0efed8454631efde6585d31d458413b`,
+> adds the first authenticated, exact-version API read backed by a real
+> PostgreSQL fixture. It keeps unsupported and unpublished copy unavailable;
+> that is implementation evidence, not protected-main or deployed evidence.
+> Next buyer increment: cut one complete screen over to this API using the

+## Voice-of-X product and technical gap
+
+ADR 0246 and PR #713 add Supplier, Employee, Business, Regulator, Investor,
+Society, and Process to the original Customer, Customer's Customer,
+Competitor, Market, and Partner source-post vocabulary. The migration,
+published SKOS concepts, product requirements, changelog, and ontology
+round-trip tests agree on the twelve codes. The design is organization-type
+neutral: public bodies, nonprofits, communities, and automated processes do
+not need to be forced into a B2B2C customer chain.
+
+The phrase "all Voice-of-X combinations" does not have a standards-backed
+finite enumeration. ISO's own stakeholder-category guidance says that the
+relevant category set varies by committee and subject; ISO 26000 requires
+stakeholder identification and engagement across organizational contexts;
+AA1000SES requires an inclusive, continuing identification process; and
+Mitchell, Agle, and Wood (1997) model stakeholder salience from combinations
+of power, legitimacy, and urgency rather than a fixed industry-role list.
+Accordingly, ADR 0246 keeps the controlled vocabulary extensible and refuses
+keyword inference, defaults, invented weights, or an asserted exhaustive
+cross-product.
+
+ADR 0256 and migration 0237 now define the persistence contract for
+evidence-bearing composition. A post keeps one source-provided
+`voc_type_code`, mirrored as its sole primary association, while every
+additional voice requires a normalized PROV-O assertion and explicit truth
+status. Half-open assignment intervals preserve a backfilled primary at
+historical cutoffs, close a replaced primary without deleting it, and permit a
+later return to the same Voice. The #717 candidate therefore addresses #748's
+A → B → A storage root cause without adding Cartesian-product codes. Protected
+delivery and synthetic PostgreSQL concurrency/cutoff evidence remain required.
+The remaining acceptance boundary is:
+
+1. preserve the imported primary voice without reclassification (implemented
+   in the candidate migration; migration 0237 replayed twice successfully on
+   an isolated PostgreSQL stack on 2026-08-27, including both primary-sync
+   triggers; a synthetic real-OIDC PostgreSQL API write also proved that the
+   imported primary remains unchanged);
+2. record each additional voice with its own source/evidence and truth state
+   (schema-enforced and candidate `post_admin` API plus live Post-popup
+   authoring implemented; synthetic authenticated PostgreSQL integration
+   proved denial before permission, the authorized write, and its normalized
+   PROV-O derivation on 2026-08-27);
+3. keeps post voice distinct from named-counterparty relationship, actor role,
+   topic, channel, lifecycle, and stakeholder-salience attributes;
+4. return only authorized associations through API, JSON-LD, CSV, filters,
+   and UI (candidate API list/detail, filters, combined post-card labels,
+   qualified JSON-LD, exact-value CSV, SHACL, and source-post evidence
+   navigation implemented; the board re-filter matches every associated voice
+   and all twelve governed atomic labels are localized across English, Korean,
+   Chinese, Japanese, and Vietnamese; one bounded query projects assignments
+   for every authorized Post even when another node type is the focus; post
+   detail lists primary and evidence-connected perspectives separately and
+   honors its knowledge cutoff; client-side JSON-LD filtering retains only
+   exact canonical repository-case node and Voice-assignment IRIs rather than
+   accepting cross-origin suffix matches; the exact-value row exposes distinct
+   carrying-Post and authorized derivation-evidence actions, while hidden
+   evidence emits neither an identifier nor a fabricated evidence count;
+   paged JSON-LD merges properties for one subject and unions its multi-Voice
+   relation rather than overwriting an earlier page); and
+5. proves zero-, one-, and multi-voice states with synthetic fixtures,
+   migration replay, ontology/SHACL, API, accessibility, and Storybook edge
+   tests before any release claim. The candidate `CombinedVoiceEvidence` scene
+   covers primary-plus-additional assignments; desktop and mobile screenshots
+   were inspected on 2026-08-27. At 390 CSS pixels the document did not
+   overflow, the named exact-value region remained horizontally scrollable,
+   and the source-post evidence action remained visible and labeled. The
+   `Post/Recorded perspectives` desktop and 390-pixel scenes were also inspected
+   on 2026-08-27; both kept each complete Voice label paired with its imported
+   or evidence-connected state without clipping or horizontal overflow. The
+   `Post/Connect perspective` ready/success scenes were inspected at 1440 and
+   390 CSS pixels on 2026-08-27: labels stay above controls, the mobile form is
+   a single column, controls meet the 44-pixel touch target, and no horizontal
+   overflow was visible.
+
+At this snapshot the repository had 42 open PRs and 11 open issues. PR #713
+head `850494c3` includes the review-driven localization of all twelve governed
+Voice labels. Its frontend, ontology publication, static-analysis, dependency,
+coverage, full-suite, CodeRabbit, Devin, and OpenCode checks passed. Strix
+failed closed before producing a vulnerability report:
+the primary NVIDIA NIM model returned HTTP 429, one configured fallback had
+reached end of life, and the OpenAI fallback reported exhausted credits. A
+same-head retry completed on 2026-08-27 with the explicit
+`STRIX_PROVIDER_UNAVAILABLE` annotation and again produced no vulnerability
+report. This
+is provider/control-plane unavailability, not a vulnerability result or
+permission to transfer an older success. Auto-merge remains enabled, while an
+independent approval is still required. PR #717 implementation head
+`d5fe4828` merges that
+parent change without force-pushing and separates the complete governed Voice
+catalog used for authoring from usage-derived Board filters, so an authorized
+administrator can attach a Voice that no visible Post carries yet. It also
+labels Voice exact-value navigation as opening the carrying Post rather than
+misrepresenting that Post as the separately recorded derivation evidence. Its
+CodeRabbit and hosted Frontend/Storybook checks passed at predecessor head
+`ebb4ef1d`; refreshed checks for exact head `d5fe4828` were queued. Focused local
+backend tests, frontend type checking/lint, and the new unused-Voice authoring
+regression passed, and the exact-value navigation tests, lint, and type check
+passed after the label repair. The paged JSON-LD union regression and Voice
+evidence navigation suite passed 23 focused frontend tests; 48 focused backend
+ontology/docstring tests also passed. The full backend suite at predecessor
+head `ebb4ef1d` passed 1,366 tests with 148 environment-dependent skips. The
+real-integration fixture now applies
+the existing migration 0042 before the expanded taxonomy migrations instead
+of seeding an incomplete or duplicate legacy catalog; the exact
+`d5fe4828` authenticated post-list integration passed in 91.54 seconds. The
+wider local frontend run had 400 passes and eight five-second timeouts under
+concurrent backend-suite load; a later App-only run had 94 passes and five
+five-second timeouts, while the hosted Frontend/Storybook job passed on
+`ebb4ef1d`. Neither local timeout run is promoted to full-suite success. An initial
+authenticated integration attempt was unavailable while Keycloak initialized;
+a later retry against the shared synthetic stack succeeded in 56.18 seconds
+and proved the permission, API, PostgreSQL,
+PROV-O, and primary-preservation assertions; no identifying source data was
+used or retained. No self-approval, admin bypass, or stale-head check transfer
+is permitted.
+
+Stacked PR #717 carries ADR 0256, migration 0237, qualified
+ontology terms, persistence/API/UI tests, and the category-validation review
+repairs plus a local candidate admin write path that creates its PROV-O
+derivation from an authorized evidence Post. Its JSON-LD projection names that
+evidence Post only when it is in the authorized visible set and omits the whole
+additional assignment otherwise, preserving the SHACL evidence minimum without
+substituting the assigned Post. It targets
+#713's branch, not protected `main`;
+its checks and review are candidate evidence only. After
+#713 reaches protected main, #717 must be synchronized, retargeted to `main`,
+and revalidated on its then-current head.
+
+Downstream Dashboard repair PR #737 exact head `a837ee5d` is stacked on base
+`7c7bb2cf`, which contains migration 0235 through a non-#713 composition but
+does not contain #713's twelve-label locale update. Its added Voice labels are
+therefore necessary on that exact base, yet overlap #713 and must be reconciled
+when the stack is eventually rebuilt on protected `main`; neither branch is a
+second taxonomy authority, and pre-parent Checks cannot transfer across that
+restack.
+The remaining user-visible gap is evidence-bearing composition. A post still
+has one source-provided `voc_type_code`; the product cannot yet represent a
+single record that intentionally carries multiple independently evidenced
+voices, nor expose the combination in filters, exports, or the ontology
+neighborhood. Do not solve this by adding every Cartesian-product code. The
+acceptance boundary for a later ADR is a normalized, provenance-bearing
+multi-voice association that:
+
+1. preserves the imported primary voice without reclassification;
+2. records each additional voice with its own source/evidence and truth state;
+3. keeps post voice distinct from named-counterparty relationship, actor role,
+   topic, channel, lifecycle, and stakeholder-salience attributes;
+4. returns only authorized associations through API, JSON-LD, CSV, filters,
+   and UI; and
+5. proves zero-, one-, and multi-voice states with synthetic fixtures,
+   migration replay, ontology/SHACL, API, accessibility, and Storybook edge
+   tests before any release claim.
+
+At this snapshot the repository had 23 open PRs and 10 open issues. PR #713
+was `MERGEABLE` but policy-blocked: exact-head backend, frontend, CodeQL,
+ontology-publication, Semgrep, OSV, Trivy, Scorecard, Noema, Devin, and
+CodeRabbit checks were successful; `coverage-source-tree` was queued; Strix
+failed closed with `STRIX_PROVIDER_UNAVAILABLE`; and an independent approval
+was still required. Auto-merge remains enabled. No self-approval, admin bypass,
+or stale-head check transfer is permitted.
+
+References for this gap use the APA 7 entries in ADR 0246. Current supporting
+standards pages were rechecked on 2026-08-27: ISO 26000:2010 remains applicable
+to all organization types and AA1000SES v3 is under development for a planned
+2027 release, so the repository continues to cite the published AA1000SES
+(2015) contract rather than treating the draft as adopted policy.

+## Current occupational semantic-layer gap
+
+ADR 0245's candidate branch publishes only a provenance-safe classification
+foundation: 23 2018 SOC major groups, four O*NET 31.0 Job Zone categories, six RIASEC interest
+types and their published adjacency, six explicitly legacy work-value clusters, seven
+revised work-style dimensions, and four ability domains. It asserts no
+occupation-to-characteristic instance profile and therefore does **not** yet
+satisfy the requested job-family, job-series, and occupation-level coverage of
+work cognition, affect, behavior, or their empirical relations. This is an
+explicit unavailable state, not a reason to infer mappings from labels.
+
+| Gap | Current evidence | Acceptance requirement |
+|---|---|---|
+| Classification depth | ADR 0245 and `lineageweave/io_taxonomy.py` expose SOC major groups only; schemes now name versioned PROV source entities and the stable O*NET 31.0 Job Zone JSON digest | Import a versioned authoritative classification release with provenance-preserving major, minor, broad, and detailed occupation identifiers; add ISCO/ESCO crosswalks only where the publishing authority supplies them |
+| Construct granularity | The candidate ontology exposes 23 high-level characteristic concepts | Publish source-versioned O*NET abilities, skills, knowledge, work activities, work context, interests, and work styles without collapsing cognition, affect, and behavior into one dimension; preserve removed Work Values only as versioned legacy content |
+| Occupation-to-construct relations | ADR 0245 deliberately declares relation properties without instance assertions | Persist released source observations with source version, occupation code, element identifier, scale identifier, value, sample/error metadata when supplied, and provenance; never invent or locally normalize a weight |
+| Job-family and job-series semantics | No authoritative employer-specific job architecture is present | Define an organization-neutral import contract that preserves the authorized source hierarchy and distinguishes standard occupation codes from employer job families/series; no label-based binding |
+| Temporal and multilevel interpretation | Static vocabulary only; no person-level inference is asserted | Version valid and transaction time, preserve occupation/organization/unit nesting and multiple membership, and require TEPP or the owning Rust psychometric service before any calibrated temporal or multilevel result |
+| Product consumption | The read model has no persisted semantic-layer consumer or authenticated UI evidence | Add a provenance-bearing API and accessible ontology exploration flow, then verify synthetic Storybook edge states plus authenticated aggregate runtime evidence without exposing identifying records |

+card overflow. Narrow inspection showed two-column metrics, readable cards and
+44px-class actions; the project journey remains intentionally horizontally

+
+PR #607 first merged as `61fd631c7bb3c57113fd19763c2c43161eeb2824`
+into #606's non-default branch. PR #606 subsequently passed the protected gate,
+so the combined TEPP-consumer and operations-dashboard implementation is now
+on `main`; the still-open TEPP producer PR #237 keeps end-to-end anchor
+acceptance unavailable.
+
+PR #604 was closed unmerged after its exact OIDC repair was composed into #605;
+its green or pending checks are not delivery evidence. PR #482 merged as
+protected-main commit `464ff25002044b9d933c8eefd36c8def7ca0ffd8`
+with package conflict markers, identifying baseline records, and an OIDC
+return-context regression. PR #603 repaired the package/privacy and
+analysis-run transaction defects through protected main at `4f53190b`; the
+OIDC defect remains delivered until #604 or the composed #605 passes the
+protected gate. Protected main is therefore not yet a release candidate.
+
+PR #592 first merged as `3b3af3b4fe9c439354433a43444e05f37ab24ea3`
+into #590's non-default stack base at `2f033ba3`. The complete stack then
+passed the protected gate and #590 merged to `main` as
+`1d1379fc59d9dac6e9c8bfa4812313e3b9e8f3c8`.
+
+PR #521 merged through protected `main` as
+`3797f063b1a7396972a749aa81f23745acccbee1`; it is release evidence and no
+longer part of the open queue. That merge also left a standalone conflict
+marker and duplicated stale tail in `CLAUDE.md`; #594 repaired it through
+protected `main` as `241be2dddf657f854cb8be54fe11d4ef48d37976`.
+
+Protected main now contains the ADR 0109 OIDC return restoration from #605,
+including fragment preservation and storage fallback. The #606 dashboard
+landing must additionally route `?post=` deep links to the Board; that focused
+regression is part of the current candidate and is not delivery evidence yet.
+
+Three systemic gates currently dominate the queue:
+
+1. **Strix visibility lookup failure (org control plane).** PR #600 exact head
+   `7580bdc9` failed before scanning because the required-workflow token could
+   not resolve this public repository after six API retries. The root repair is
+   ContextualWisdomLab/.github#1320 at `3b9b2380`: ordinary PR, push, and
+   schedule runs use trusted event visibility; cross-repository dispatch keeps
+   authoritative public/private/internal visibility; private and internal
+   repositories remain on private-capable providers. The exact head also
+   composes the executable fallback contract and classifies bounded NVIDIA
+   `ServiceUnavailableError` overload evidence as retryable across configured
+   distinct models without weakening exhaustion or vulnerability fail-close.
+   A hosted fallback then completed with zero vulnerabilities but was rejected
+   because the generic warning gate treated Strix's fallback-model banner and
+   a Hugging Face unauthenticated-download notice as provider failures. The
+   current head removes only those two exact scanner notices before the
+   existing general warning and explicit 429/provider failure checks. The
+   current head also clears a foreign NVIDIA/OpenRouter endpoint before a
+   direct-OpenAI fallback while retaining an explicitly configured
+   direct-OpenAI primary endpoint. The prior full quick-gate harness, overload
+   path, 12 visibility-contract tests, and the focused cross-provider endpoint
+   contract passed; exact-head hosted revalidation remains pending. It is blocked on
+   hosted exact-head gates and independent review, so no repaired
+   protected-main Strix runtime evidence exists yet.
+2. **Strix provider unavailability (org control plane).** The central required
+   Strix scan on .github#1320 failed when NVIDIA returned `Service temporarily
+   overloaded`; the gate correctly failed closed but did not try its configured
+   distinct fallbacks because the service-unavailable classifier excluded the
+   NVIDIA provider. Exact head `3b9b2380` composes that execution repair and the
+   two exact non-fatal scanner-notice exclusions while keeping
+   incomplete exhaustion non-passing. This is still an unmerged control-plane
+   proposal, not protected-main or downstream runtime evidence.
+3. **Current-head independent approval.** The org merge scheduler requires
+   `reviewDecision == APPROVED` plus complete Strix evidence on the exact
+   head. Bot review evidence regenerates per push, so any repair push resets
+   the review clock by design; this is expected and not a bypass target.

+
+This documentation is owned by protected `main` again: the #426 stack landed,
+so hidden-stack merges (#494, #497, #499, #505, #509 into unprotected parent
+branches) are historical context only and no longer gate anything.
+
+The current protected-`main` and exact #507 trees are clean of the private
+runtime source-table identifier present in the closed #506 head and older
+public history. Do not reproduce or hint at its value. Historical remediation
+requires the ADR 0001 incident process and security/privacy-owner coordination;
+never force-push or delete evidence ad hoc.
+
+The Grok durable hourly loop and the central thin GitHub Actions caller
+ContextualWisdomLab/.github#1259 (minute 4, `pr-review-fix-scheduler.yml`)
+both target this repository. Do not add a LineageWeave-local duplicate
+workflow. ContextualWisdomLab/.github#1258 merged at exact head `897819c4` to
+repair the pnpm/coverage-evidence workflow; newly created exact PR heads must
+still prove the runtime behavior because merged workflow source alone is not
+check evidence.
+
+Figma design-system boundary (ADR 0002): File ID `1Su3lDRmiZdcUs47t1QwIX`.
+The sanitized file now contains synthetic Event Lineage desktop (`5:14`) and
+mobile (`5:15`) frames with graph direction, event dates, an inference
+boundary, and exact fused-score evidence. Do not copy source-organization
+content into this repository. Storybook remains the executable scene and
+edge-case inventory for repeated web objects; rendered code-to-Figma parity
+still requires same-viewport browser comparison on an exact candidate head.
+
+## 2. User-visible capability baseline
+
+Substantially present on protected `main`:
+
+- PostgreSQL-backed import, normalized provenance, cutoff-aware analysis runs,
+  source revisions, lineage reconstruction, and explicit unavailable states.
+- Authenticated workspace navigation, post detail, localized summaries, 5W1H,
+  R&R/Keyman, evidence citations, chat, organization hierarchy, and lineage DAG
+  (`frontend/src/LineageDag.tsx` is on `main`; the old “DAG view missing”
+  baseline entry is stale).
+- Semantic paragraph/list/table/image-region units that preserve the source
+  representation and provenance instead of flattening it into one body string.
+- FJA→I/O-Psychology semantic layer (ADR 0251): the published DOT/FJA
+  Data/People/Things worker functions (ADR 0232) project into disjoint
+  cognitive, affective, and behavioral constructs with APA 7th anchors,
+  SHACL validation, and a deterministic typed read model
+  (`lineageweave/iopsy_taxonomy.py`); no fitted weight or O*NET/ADR 0248
+  crosswalk is asserted (ADR 0145).
+- Contextual-orchestrator boundaries for adjudication, extraction, summaries,
+  chat, embeddings, and VISION; null channels remain unavailable and are
+  dropped from score fusion.
+- W3C PROV-O projection through normalized provenance tables, with the
+  knowledge graph retained as an explicit navigation projection.
+- Keyverse/Keycloak OIDC, RankWeave fusion port, TEPP measurement client,
+  ThreadWeave tree assembly.
+
+These statements describe source capability, not authenticated production
+corpus acceptance or protected release.
+
+## 3. Historical open-PR inventory (superseded by §1)
+
+Heads below are queue evidence captured at snapshot time; recheck SHA,
+checks, unresolved threads, and independent approval immediately before any
+merge claim. Do not self-approve, force-push, or transfer stale review
+evidence across heads. The org merge scheduler merges only when
+`reviewDecision == APPROVED` on the exact head and Strix evidence is complete.
+
+### 3.0 Shared systemic gate
+
+| Gate | Evidence | Durable repair |
+| --- | --- | --- |
+| Strix provider unavailability | `nvidia_nim/nvidia/nemotron-3-super-120b-a12b` and `openai-direct/gpt-5.6-luna` failed authoritatively across unrelated heads | ContextualWisdomLab/.github#1263 at `ab3d7645` proposes executable Azure/cross-provider fallbacks but remains open/conflicting; repair that branch without weakening the required gate |
+| ADR 0109 login repair debt | Eight branches cut from the pre-repair base carried the unauthenticated `AdminPanel` + unused-OIDC-helper `tsc -b` failure | Same verified two-line repair applied to #521, #522, #552, #553, #554, #556, #558, #560 during this loop; frontend lint/test/build verified locally |

+
+## 4. Open issues (complete live queue; product acceptance remaining on `main`)
+
+| Issue | User-visible gap | Active PR |
+| ---: | --- | --- |
+| #79 | Milestone 2: port verified direct-PostgreSQL analysis into the protected architecture | analysis-run registry on `main`; remaining runtime bridge |
+| #87 | Milestone 2.1 normalized runtime-analysis schema bridge | related analysis-run work |
+| #269 | Authenticated Global Ask MCP browser-safe and admission-bounded | Ask stack |
+| #271 | Evidence-honest knowledge-cutoff scope on Global Ask | #658; still open and not protected-main evidence |
+| #272 | Verify Global Ask KG/ontology/semantic claims with public SearXNG evidence | #632 preserves internal provenance; public verification acceptance remains open |
+| #277 | TEPP: persist accepted receipts, poll completed results, keep measurement authority distinct | #657 consumer lifecycle; executable producer route remains unavailable |
+| #280 | Full project-lifecycle history and handover intervals | #640 adds case/project journeys and #663 adds evidence-backed Project exploration; authoritative lifecycle reconciliation remains #284 |
+| #284 | Authoritative lifecycle ingestion and idempotent reconciliation | No active delivery PR confirmed |
+| #338 | Evidence-bounded email/project lineage contract for Naruon consumption | #704 recreates the provider-side contract on current `main` without arbitrary fusion weights; #343 remains only a non-default-stack merge and #355 is a distinct calendar contract |
+| #611 | Decompose closed PR #490 ADR 0133–0137 evidence without transferring stale branch state | #631 supplies the current-main inventory only; focused implementation PRs and tests for every unmet criterion are still required |
+
+## 5. Open product and technical gaps
+
+| Gap | Current evidence | Acceptance requirement |
+| --- | --- | --- |
+| Protected release | 12 open PRs at snapshot, all targeting `main` with normal auto-merge enabled. None has the required independent approval, and running checks on #631/#632/#663 are not treated as blockers for safe work on other PRs. #666's merge into the non-default #663 branch is not protected-main delivery | Terminal exact-head checks, no unresolved threads, two independent approvals including last-push approval, protected squash-merge SHA |
+| CI queue release latency | Two Tests runs for already merged PRs occupied the available runner slots while 54 newer runs remained queued. Manual cancellation released the stale work, but the central close workflow was itself queued behind those runs. #634 merged into #631's non-default branch and reuses the repository's existing per-PR concurrency group so a jobless close event can cancel obsolete Tests work before runner allocation; this is not protected-main delivery | Merge #631 through its refreshed protected gate; close a synthetic PR while its Tests run is active and verify the old run becomes cancelled, the close-event jobs remain skipped, and a newer exact-head run starts without manual intervention |
+| Evidence-grounded operations workspace | Protected-main #614 delivers governed semantic Ask, live Similar VOC, disjoint pending/failed analysis metrics, full Storybook state inventory, and current desktop/mobile screenshot evidence. Authorized-corpus backfill acceptance remains unavailable | Perform authenticated authorized-corpus acceptance with aggregate evidence and retain fail-closed no-match behavior |
+| Shared frontend gate | The ADR 0109 login repair is on protected `main`; eight older branches carried the defect and received the same verified repair this loop (#521–#560) | Keep every future branch cut from post-repair bases; re-verify with frontend lint/test/build before push |
+| Identifying baseline regression | `main` gap file listed real post identifiers; separately, closed #506 and pre-existing public history contain a private runtime source-table identifier, while current `main` and #507 trees are clean | Land this non-identifying rewrite, then coordinate ADR 0001 history remediation with security/privacy owners; do not reproduce the value, force-push, or delete evidence ad hoc |
+| Authorized-corpus runtime | Repository tests use synthetic fixtures; private records remain outside git | Authenticated runtime validation returning only aggregate, non-identifying evidence |
+| Concurrent web responsiveness | ADR 0204 releases pooled transactions during provider work, and the synthetic Compose boundary has an authenticated k6 E2E harness for Ask enqueue, concurrent reads, and job polling. PR #633's measured landing-query and event-loop work merged into open parent #629 rather than protected `main`; its aggregate observation improved 25-VU throughput but did not establish a latency SLO. The current exact #629 also persists each completed relation verification before propagating a later provider failure | Land #629 through its refreshed protected gate, rebuild that exact-head application image, and repeat `make load-http` with declared environment concurrency/window and retained raw distributions/resource configuration; set no SLO until representative capacity evidence is approved |
+| Image understanding | Region, OCR, and description work exists across active heads (#405, #419), but current runtime acceptance has not yet proved table-image structure, complete region coverage, or summary/image readiness together | Orchestrator-backed rendered workflow, original/derived asset provenance, region-before-OCR processing, and honest unsupported states; reconcile ADR 0052's image-bearing summary readiness with ADR 0098 before changing sequencing |
+| Semantic source rendering | Paragraph, table, list, formula, and indentation work exists across stacks (#394, #427, #448–#450); #515 adds synthetic backend/frontend parity for deterministic rows/cells, footnote boundaries, and encoded scripts | Land the #427 → #515 stack, then gather authenticated browser evidence that list nesting, continuation alignment, and formula units render without authoring-layout artifacts |
+| Event and project semantics | #663 is the largest current user-visible gap slice: evidence-backed Project nodes, bounded traversal, cutoff/snapshot fencing, exact-value table parity, and localized graph labels. Focus visibility, label-bound, and temporal test-double regressions are repaired. #666's heuristic removal is composed into this parent but is not separately protected-main evidence. #640 separately adds project journeys without claiming authoritative lifecycle status | Combined #663 must pass exact-head checks and independent approval before protected merge. Aggregate authenticated evidence must still prove distinct projects/events and handover intervals without promoting co-occurrence |
+| Voice primary history | Protected `main` `bbb19192` includes ADR 0252 / #761 (migration 0243, GiST primary-period exclusion, `clock_timestamp()` after the source-row lock, API/ontology half-open cutoff SQL). v2.22.1 adds synthetic PostgreSQL integration tests for A → B → A at before/between/after cutoffs, concurrent primary updates, additional-assignment close, and 0237→0243 trigger replay. This is not yet protected-main evidence | Land the live-test slice through the protected gate with independent exact-head APPROVE; close #748 only after that protected delivery |
+| Knowledge Graph readability | #659 recreates the token-backed node-type repair on current `main`, including regression coverage; it is open and therefore not protected-main evidence | Merge #659 normally, then verify light/dark contrast, keyboard graph navigation, full labels, and evidence tables in the authenticated rendered surface |
+| Source-code lookup UX | Source state/detail codes remain evidence-bearing machine values and current detail presentation is dense | Catalog-backed display labels with raw-code provenance, compact 5W1H/source-detail hierarchy, keyboard access, and no unsupported customer/project binding |
+| Calendar / Naruon | #355 delivered the projection contract; v2.17.0 wires operator consumption without forwarding the end-user token. Naruon producer, provider/consumer fixtures, and protected merge remain open (#336) | Verify observed events against the published schema without invented events; keep commitments available when the channel is unwired |
+| SKOS organization aliases | Catalog binding and chip caption live on #480 / #482 | One catalog row per corroborated org; companion caption is hint-only until bound |
+| Event Lineage evidence | Channel evidence and Allen relations live on #387 / #484 | Persist channel scores, explain them in the popup, never invent a fused score |
+| Scientific measurement | Durable accepted TEPP receipts and LineageWeave #614's exact accepted snapshot/cutoff/run/pair-count consumer are protected; TEPP #237 remains open, so no registered producer artifact exists yet. #387 removes inferred/default persistence weights, but several older reconstruction tests still pass hand-authored numeric dictionaries that are not estimator evidence | Land TEPP #237 through its protected gate, then replace remaining reconstruction-test constants with provenance-bearing fast-mlsirm estimates over synthetic fixtures. Retain true-parameter RMSE recovery as the acceptance bar |
+| Asynchronous authorization | Protected `main` rebuilds Global Ask worker scope after the bearer token leaves the request; #468 now persists exact Keyverse organization/process-unit scope in 3NF child tables and intersects it with current affiliations | Land #468 through the protected gate; prove a second affiliation and a revoked process unit cannot widen delayed-job evidence |
+| Planned-facility intent | Planned-facility relationship intent remains only on closed, unmerged #490; earlier stack-only merges were not protected delivery | Recreate the evidence-backed slice on a current base and land through protected `main` before a release claim |
+| Accessibility and responsive UX | #602 delivered base post-detail modal semantics; #605 adds selected-post refocus, collapsed/hidden/inert/CSS-invisible focus exclusion across both modal types, readable evidence separators, focused tests, and desktop/mobile Storybook screenshots | Land #605 through the protected gate, then complete screen-reader and authenticated Playwright acceptance on the exact release head |
+| Design tokens and repeated objects | Token extraction started; sanitized Figma Event Lineage desktop/mobile frames exist, while other repeated product surfaces remain incomplete | Tokens in CSS + Storybook stories for board, popup, DAG, Ask, calendar, forms, charts; same-viewport Figma/runtime visual comparison before release |
+| Frontend delivery performance | #644 implements a native dynamic-import boundary for conditional workspace surfaces and retains accessible loading/error states; exact-head checks passed but the PR is not protected-main evidence | Merge #644 normally, rebuild the protected-main production bundle, and retain the measured chunk inventory rather than raising the warning limit |
+| External integrations | Search, Zotero, calendar, Keyverse, orchestrator, RankWeave, ThreadWeave, TEPP, DiskSage, wardnet | Provider conformance, failure/reconciliation behavior, and provenance-bearing integration evidence |
+| Naruon email/project lineage | #704 provides a strict store-agnostic v1 contract, opaque evidence references, observed/inferred truth separation, knowledge-cutoff admission, and explicit unavailable states. Inferred edges require an injected provenance-bearing fast-mlsirm estimate; no local default weight exists | Merge #704 through protected `main`, publish an immutable attested artifact, then enable the Naruon consumer only against that released version and its contract fixtures |
+| MSA / modular reuse | LineageWeave must run standalone and as a consumer of org packages | Do not reimplement RankWeave/TEPP/orchestrator/ThreadWeave/Keyverse; fix upstream and PR there |
+| Accelerator runtime ownership | ADR 0076/0208 already prohibit local model and mathematical ownership; ADR 0237 now defines MLX as a native orchestrator-side service and TEPP/fast-mlsirm CUDA/OpenCL/CPU profiles as scientific-compute-owner deployments, so LineageWeave Compose remains device-neutral. RankWeave remains the dependency-free Python retrieval-fusion/evaluation owner behind its published contract | TEPP and fast-mlsirm must publish deterministic CPU recovery plus conformance evidence for every advertised CUDA/OpenCL profile; contextual-orchestrator must prove native MLX availability through its provider-neutral health/contract boundary. LineageWeave accepts only versioned, provenance-bearing envelopes and fails closed when the owner is unavailable |
+| Product contract authority | The current LineageWeave PRD records exact-case ecosystem authorities. TEPP, fast-mlsirm, keyverse, ThreadWeave, and RankWeave PR #41 have standalone PRDs; RankWeave's remains unmerged. contextual-orchestrator, disksage, and wardnet still rely on product/architecture documents, and naruon has only a scoped Topic Intelligence PRD | Keep ADRs normative, preserve canonical repository case in machine references, land the pending PRDs, and add standalone PRDs in each remaining owning repository before cross-product release claims exceed its documented boundary |
+| Release quality | PR #660 is now on protected `main`; its pre-merge full Python suite passed 1,352 tests with 17 skips, but release-wide frontend, Storybook, security, browser, and runtime acceptance remain unproven on one exact protected head | Repository-wide coverage, docstrings, Storybook, security, browser, and release evidence on one exact head |
+| PII | Masking would paralyze the product; ADR 0001 forbids identifying artifacts in git | ABAC + authorized runtime; synthetic fixtures in git; no mask-in-place that drops names the operator must read |
+| Database | PostgreSQL, 3NF, snake_case ≥ two words, hot-partition and lock policy | No file DBs; read/write split if lock management fails; whitelist every migration |
+
+### 5.1 Closed PR #490 decomposition (issue #611)
+
+Protected `main` at `04e6b610` and the three open PRs present during the initial
+decomposition were rechecked; the later audit snapshot above includes #631
+itself as the fourth open PR. Protected `main` contains none of PR #490. That PR remains
+closed, unmerged branch evidence; its ADR 0133–0137 files are not normative and
+its 321-file tree must not be replayed. Current-main code and schema searches
+give this delivery matrix:
+
+| Closed-branch decision | Current-main classification | Smallest remaining delivery |
+| --- | --- | --- |
+| ADR 0133 source-reference research | Partial foundation: protected `main` has the self-hosted SearXNG relation-verification client and fail-closed configuration, but it verifies an already extracted relation. It has no source-unit/image-region lead, cited-resource retrieval, claim judgment, or normalized research citation workflow | One post-scoped lead-to-citation slice that reuses the self-hosted SearXNG search boundary, adds public-target SSRF/redirect rejection for result retrieval, and judges through contextual-orchestrator with explicit unavailable outcomes |
+| ADR 0134 token-backed exception messages | Partial: sanitized next-action failures exist, but no shared token-backed exception component or complete Storybook error inventory exists | Migrate one existing unavailable flow to one shared accessible alert and verify its success, unavailable, and retry states |
+| ADR 0135 kind/status-exact analysis actions | Partial: protected `main` has kind-aware start/retry controls plus normative analysis-run, TEPP, cutoff-body, and channel-evidence contracts; it does not contain the closed branch's unified guidance component or its full kind × status interaction inventory | Test the current run-kind/status matrix first, then add only a proven missing state/control pair rather than copying the closed-branch function |
+| ADR 0136 per-post Ask history | Partial: `post_chat_result` / `post_chat_citation`, the authorized post Chat API, and its linear exchange history are on protected `main`. Account-and-post-scoped sessions, ordered turns, list/select/new controls, and batched citation reauthorization are not | Define the 3NF account/post session boundary, bounded batch reauthorization, and one authorized list/load/write path before adding the conversation picker |

+
+This matrix satisfies only #611's current-main inventory step. Issue #611
+remains open: every unmet criterion above still needs a focused regression test
+and exact-head current-main implementation PR before its acceptance criteria
+are satisfied. No stale check, review, or implementation is transferred from
+#490.

+## 6. UI-UX acceptance inventory (must be defined, reviewed, applied, audited)
+
+Each item needs a Storybook scene, an edge-case story, and an automated check
+before a commercial release claim. Figma File ID `1Su3lDRmiZdcUs47t1QwIX`.
+
+| Dimension | Current | Gap |
+| --- | --- | --- |
+| Accessibility | Partial labels/roles on board, popup, login | WCAG 2.2 AA on login, board, popup, Ask, calendar, admin; focus order; live regions |
+| Touch & Interaction | Click-first popup and lists | 44px targets, swipe/escape to dismiss popup, no hover-only actions |
+| Performance | Board caps and hint render limits exist | Interaction-to-next-paint on board search, DAG, Ask; no N+1 (#358) |
+| Style Selection | Korean UI standards merged (#347) | Tokenized light/dark; Anti-Slop-UI density; no decorative noise |
+| Layout & Responsive | Desktop popup shell | 402px-class phone layout; stacked GNB; readable DAG |
+| Typography & Color | Badge tokens extracted | Contrast on badges, links, error/status; no raw hex in components |

+
+## 7. Ecosystem leverage order
+
+Reuse before rebuild. Consume these ContextualWisdomLab packages in this order
+of leverage; open connector PRs there when the defect is upstream:
+
+1. **contextual-orchestrator** — every LLM/VISION/embedding call (Fugu / Conductor / TRINITY routing). Never a raw provider SDK.
+2. **Keyverse** — OIDC issuer, JWKS, tenant principals.
+3. **RankWeave** — fused scores and rankings; never invent a fused score or theta.
+4. **TEPP** — calibrated measurement; persist receipts; no local reimplementation.
+5. **fast-mlsirm** — GRM/GPCM/CAT/FIPC recovery tests (#451–#454) must stay true-parameter RMSE.
+6. **ThreadWeave** — tree assembly.
+7. **Naruon** — calendar and email/project lineage projection (#336, #338, #355).
+8. **DiskSage / wardnet** — storage and network policy as needed.
+9. **ContextualWisdomLab/.github** — required review workflows (OpenCode, Strix, Noema) and the LineageWeave hourly caller (#1259). If stacked PRs miss central review or coverage-evidence fails on pnpm 9 (`--trust-lockfile` is pnpm 11.3) or a missing Vitest coverage provider, fix the org workflow (#1258), not a local bypass.
+
+## 8. Public ontology publication boundary
+
+- PR #426 publishes fragment-addressable HTML, byte-identical Turtle,
+  isomorphic JSON-LD and N-Triples, the PROV-O support profile, and a
+  source-digest manifest from the authoritative ontology.
+- Pull requests validate only. Only protected `main` may publish, and the
+  generated-directory marker, linked-IRI, duplicate-fragment, symlink, and
+  source-overlap checks fail closed.
+- The lowercase knowledge-graph namespace and repository-case support-profile
+  namespace remain distinct until issue #372 delivers a versioned migration
+  and compatibility decision; this publication PR rewrites neither identity.
+- Until the protected deployment and exact URL checks succeed, the public
+  ontology endpoint remains unavailable and must not be represented as live.
+
+## 9. Evidence boundaries
+
+- Never add a real record, title, name, identifier, screenshot, log, benchmark
+  artifact, or documentation example to this repository.
+- Attendance or co-occurrence is not responsibility, project, customer, or
+  affiliation evidence. Preserve uncertainty and provenance.
+- Missing transport, model capability, accepted envelope, or persistence is
+  unavailable or failed evidence, never a placeholder result.
+- Local green tests, bot statuses, auto-merge, and warning-only checks do not
+  prove a protected merge.
+- Re-fetch base/head SHAs, checks, review threads, approvals, rulesets, and the
+  merge SHA immediately before any lifecycle claim.
+- Do not self-approve. Independent OpenCode / Strix / Noema review is required.
+- Do not force-push. Do not treat GitHub Checks duration as a blocker; repair
+  the failing check instead.
+- `COPILOT_GITHUB_TOKEN` is not used.
+
+## 10. Next acceptance loop (autonomous merge order)
+
+Process every open PR in ascending number order, considering leverage; for
+each: check reviews → repair → re-verify Checks → merge → continue. Checks and
+review latency are never blockers — keep working while they settle.
+
+1. Revalidate Strix after merged ContextualWisdomLab/.github#1320, reconcile
+   open .github#1263, and land the atomic hourly LineageWeave caller in open
+   .github#1288 only through their protected gates.
+2. Process main-targeted PRs #629, #631, #632, #639, #640, #643, #644, #657,
+   #658, #659, #660, and #663 only after each exact head shows terminal green
+   required checks plus current-head independent approval. Treat #666's
+   non-default-branch merge only as part of #663's combined candidate and
+   collect all protected evidence on #663's exact head.
+3. While hosted checks or independent reviews wait, resume user-visible gaps
+   from §5 in leverage order:
+   external semantic verification (#272), Naruon calendar (#355/#336), and
+   authenticated operations/ontology publication acceptance. Event Lineage
+   evidence shipped in merged PR #387 and closed issue #274 is not an open gap.
+4. Rename remaining `[Buyer Gap]` issue titles to neutral product-object
+   naming per repository convention (no "Buyer" for internal objects).
+5. Keep psychometric tests as true-parameter recovery (RMSE); never fixture
+   tautologies, invented theta, or hand-authored numeric weights. Remove
+   weights from tests that do not exercise fusion; fusion tests must consume
+   provenance-bearing fast-mlsirm estimates over synthetic fixtures.
+6. Run frontend lint/test/build/Storybook, backend tests, and authenticated
+   browser/accessibility checks on the exact candidate release head.
+7. Fix only evidence-backed failures and repeat the protected merge gate.
+8. Refresh this file each loop with the exact queue state.
+
+## 11. Spec pointers (derive, do not fork)
+
+- Product/architecture: `ARCHITECTURE.md`, `AGENTS.md`, `CLAUDE.md`
+- Research grounding: ADR 0084, `docs/lineage-bi-research-notes.md`
+- Demo identity: ADR 0001
+- Figma boundary: ADR 0002 (File ID `1Su3lDRmiZdcUs47t1QwIX`)
+- Orchestrator / paper-grounded models: ADR 0015, ADR 0076 (Fugu, TRINITY, Conductor)
+- Ontology / PROV-O / SKOS: ADR 0004, ADR 0011, issue #372
+- Analysis runs / TEPP: ADR 0013–0023, issue #79 / #277
+- Calendar / Naruon: issues #336 / #338, PR #355, operator consumption v2.17.0
+- Ask Agent: issues #269–#272, #358–#363
+
+Citations in doctoring and ADRs use APA 7th. Do not invent a heuristic where
+the papers leave the decision undecided.

-## Voice-of-X product and technical gap
-
-ADR 0246 and PR #713 add Supplier, Employee, Business, Regulator, Investor,
-Society, and Process to the original Customer, Customer's Customer,
-Competitor, Market, and Partner source-post vocabulary. The migration,
-published SKOS concepts, product requirements, changelog, and ontology
-round-trip tests agree on the twelve codes. The design is organization-type
-neutral: public bodies, nonprofits, communities, and automated processes do
-not need to be forced into a B2B2C customer chain.
-
-The phrase "all Voice-of-X combinations" does not have a standards-backed
-finite enumeration. ISO's own stakeholder-category guidance says that the
-relevant category set varies by committee and subject; ISO 26000 requires
-stakeholder identification and engagement across organizational contexts;
-AA1000SES requires an inclusive, continuing identification process; and
-Mitchell, Agle, and Wood (1997) model stakeholder salience from combinations
-of power, legitimacy, and urgency rather than a fixed industry-role list.
-Accordingly, ADR 0246 keeps the controlled vocabulary extensible and refuses
-keyword inference, defaults, invented weights, or an asserted exhaustive
-cross-product.
-
-ADR 0256 and migration 0237 now define the persistence contract for
-evidence-bearing composition. A post keeps one source-provided
-`voc_type_code`, mirrored as its sole primary association, while every
-additional voice requires a normalized PROV-O assertion and explicit truth
-status. Half-open assignment intervals preserve a backfilled primary at
-historical cutoffs, close a replaced primary without deleting it, and permit a
-later return to the same Voice. The #717 candidate therefore addresses #748's
-A → B → A storage root cause without adding Cartesian-product codes. Protected
-delivery and synthetic PostgreSQL concurrency/cutoff evidence remain required.
-The remaining acceptance boundary is:
-
-1. preserve the imported primary voice without reclassification (implemented
-   in the candidate migration; migration 0237 replayed twice successfully on
-   an isolated PostgreSQL stack on 2026-08-27, including both primary-sync
-   triggers; a synthetic real-OIDC PostgreSQL API write also proved that the
-   imported primary remains unchanged);
-2. record each additional voice with its own source/evidence and truth state
-   (schema-enforced and candidate `post_admin` API plus live Post-popup
-   authoring implemented; synthetic authenticated PostgreSQL integration
-   proved denial before permission, the authorized write, and its normalized
-   PROV-O derivation on 2026-08-27);
-3. keeps post voice distinct from named-counterparty relationship, actor role,
-   topic, channel, lifecycle, and stakeholder-salience attributes;
-4. return only authorized associations through API, JSON-LD, CSV, filters,
-   and UI (candidate API list/detail, filters, combined post-card labels,
-   qualified JSON-LD, exact-value CSV, SHACL, and source-post evidence
-   navigation implemented; the board re-filter matches every associated voice
-   and all twelve governed atomic labels are localized across English, Korean,
-   Chinese, Japanese, and Vietnamese; one bounded query projects assignments
-   for every authorized Post even when another node type is the focus; post
-   detail lists primary and evidence-connected perspectives separately and
-   honors its knowledge cutoff; client-side JSON-LD filtering retains only
-   exact canonical repository-case node and Voice-assignment IRIs rather than
-   accepting cross-origin suffix matches; the exact-value row exposes distinct
-   carrying-Post and authorized derivation-evidence actions, while hidden
-   evidence emits neither an identifier nor a fabricated evidence count;
-   paged JSON-LD merges properties for one subject and unions its multi-Voice
-   relation rather than overwriting an earlier page); and
-5. proves zero-, one-, and multi-voice states with synthetic fixtures,
-   migration replay, ontology/SHACL, API, accessibility, and Storybook edge
-   tests before any release claim. The candidate `CombinedVoiceEvidence` scene
-   covers primary-plus-additional assignments; desktop and mobile screenshots
-   were inspected on 2026-08-27. At 390 CSS pixels the document did not
-   overflow, the named exact-value region remained horizontally scrollable,
-   and the source-post evidence action remained visible and labeled. The
-   `Post/Recorded perspectives` desktop and 390-pixel scenes were also inspected
-   on 2026-08-27; both kept each complete Voice label paired with its imported
-   or evidence-connected state without clipping or horizontal overflow. The
-   `Post/Connect perspective` ready/success scenes were inspected at 1440 and
-   390 CSS pixels on 2026-08-27: labels stay above controls, the mobile form is
-   a single column, controls meet the 44-pixel touch target, and no horizontal
-   overflow was visible.
-
-At this snapshot the repository had 42 open PRs and 11 open issues. PR #713
-head `850494c3` includes the review-driven localization of all twelve governed
-Voice labels. Its frontend, ontology publication, static-analysis, dependency,
-coverage, full-suite, CodeRabbit, Devin, and OpenCode checks passed. Strix
-failed closed before producing a vulnerability report:
-the primary NVIDIA NIM model returned HTTP 429, one configured fallback had
-reached end of life, and the OpenAI fallback reported exhausted credits. A
-same-head retry completed on 2026-08-27 with the explicit
-`STRIX_PROVIDER_UNAVAILABLE` annotation and again produced no vulnerability
-report. This
-is provider/control-plane unavailability, not a vulnerability result or
-permission to transfer an older success. Auto-merge remains enabled, while an
-independent approval is still required. PR #717 implementation head
-`d5fe4828` merges that
-parent change without force-pushing and separates the complete governed Voice
-catalog used for authoring from usage-derived Board filters, so an authorized
-administrator can attach a Voice that no visible Post carries yet. It also
-labels Voice exact-value navigation as opening the carrying Post rather than
-misrepresenting that Post as the separately recorded derivation evidence. Its
-CodeRabbit and hosted Frontend/Storybook checks passed at predecessor head
-`ebb4ef1d`; refreshed checks for exact head `d5fe4828` were queued. Focused local
-backend tests, frontend type checking/lint, and the new unused-Voice authoring
-regression passed, and the exact-value navigation tests, lint, and type check
-passed after the label repair. The paged JSON-LD union regression and Voice
-evidence navigation suite passed 23 focused frontend tests; 48 focused backend
-ontology/docstring tests also passed. The full backend suite at predecessor
-head `ebb4ef1d` passed 1,366 tests with 148 environment-dependent skips. The
-real-integration fixture now applies
-the existing migration 0042 before the expanded taxonomy migrations instead
-of seeding an incomplete or duplicate legacy catalog; the exact
-`d5fe4828` authenticated post-list integration passed in 91.54 seconds. The
-wider local frontend run had 400 passes and eight five-second timeouts under
-concurrent backend-suite load; a later App-only run had 94 passes and five
-five-second timeouts, while the hosted Frontend/Storybook job passed on
-`ebb4ef1d`. Neither local timeout run is promoted to full-suite success. An initial
-authenticated integration attempt was unavailable while Keycloak initialized;
-a later retry against the shared synthetic stack succeeded in 56.18 seconds
-and proved the permission, API, PostgreSQL,
-PROV-O, and primary-preservation assertions; no identifying source data was
-used or retained. No self-approval, admin bypass, or stale-head check transfer
-is permitted.
-
-Stacked PR #717 carries ADR 0256, migration 0237, qualified
-ontology terms, persistence/API/UI tests, and the category-validation review
-repairs plus a local candidate admin write path that creates its PROV-O
-derivation from an authorized evidence Post. Its JSON-LD projection names that
-evidence Post only when it is in the authorized visible set and omits the whole
-additional assignment otherwise, preserving the SHACL evidence minimum without
-substituting the assigned Post. It targets
-#713's branch, not protected `main`;
-its checks and review are candidate evidence only. After
-#713 reaches protected main, #717 must be synchronized, retargeted to `main`,
-and revalidated on its then-current head.
-
-Downstream Dashboard repair PR #737 exact head `a837ee5d` is stacked on base
-`7c7bb2cf`, which contains migration 0235 through a non-#713 composition but
-does not contain #713's twelve-label locale update. Its added Voice labels are
-therefore necessary on that exact base, yet overlap #713 and must be reconciled
-when the stack is eventually rebuilt on protected `main`; neither branch is a
-second taxonomy authority, and pre-parent Checks cannot transfer across that
-restack.
-The remaining user-visible gap is evidence-bearing composition. A post still
-has one source-provided `voc_type_code`; the product cannot yet represent a
-single record that intentionally carries multiple independently evidenced
-voices, nor expose the combination in filters, exports, or the ontology
-neighborhood. Do not solve this by adding every Cartesian-product code. The
-acceptance boundary for a later ADR is a normalized, provenance-bearing
-multi-voice association that:
-
-1. preserves the imported primary voice without reclassification;
-2. records each additional voice with its own source/evidence and truth state;
-3. keeps post voice distinct from named-counterparty relationship, actor role,
-   topic, channel, lifecycle, and stakeholder-salience attributes;
-4. returns only authorized associations through API, JSON-LD, CSV, filters,
-   and UI; and
-5. proves zero-, one-, and multi-voice states with synthetic fixtures,
-   migration replay, ontology/SHACL, API, accessibility, and Storybook edge
-   tests before any release claim.
-
-At this snapshot the repository had 23 open PRs and 10 open issues. PR #713
-was `MERGEABLE` but policy-blocked: exact-head backend, frontend, CodeQL,
-ontology-publication, Semgrep, OSV, Trivy, Scorecard, Noema, Devin, and
-CodeRabbit checks were successful; `coverage-source-tree` was queued; Strix
-failed closed with `STRIX_PROVIDER_UNAVAILABLE`; and an independent approval
-was still required. Auto-merge remains enabled. No self-approval, admin bypass,
-or stale-head check transfer is permitted.
-
-References for this gap use the APA 7 entries in ADR 0246. Current supporting
-standards pages were rechecked on 2026-08-27: ISO 26000:2010 remains applicable
-to all organization types and AA1000SES v3 is under development for a planned
-2027 release, so the repository continues to cite the published AA1000SES
-(2015) contract rather than treating the draft as adopted policy.

-## Current occupational semantic-layer gap
-
-ADR 0245's candidate branch publishes only a provenance-safe classification
-foundation: 23 2018 SOC major groups, four O*NET 31.0 Job Zone categories, six RIASEC interest
-types and their published adjacency, six explicitly legacy work-value clusters, seven
-revised work-style dimensions, and four ability domains. It asserts no
-occupation-to-characteristic instance profile and therefore does **not** yet
-satisfy the requested job-family, job-series, and occupation-level coverage of
-work cognition, affect, behavior, or their empirical relations. This is an
-explicit unavailable state, not a reason to infer mappings from labels.
-
-| Gap | Current evidence | Acceptance requirement |
-|---|---|---|
-| Classification depth | ADR 0245 and `lineageweave/io_taxonomy.py` expose SOC major groups only; schemes now name versioned PROV source entities and the stable O*NET 31.0 Job Zone JSON digest | Import a versioned authoritative classification release with provenance-preserving major, minor, broad, and detailed occupation identifiers; add ISCO/ESCO crosswalks only where the publishing authority supplies them |
-| Construct granularity | The candidate ontology exposes 23 high-level characteristic concepts | Publish source-versioned O*NET abilities, skills, knowledge, work activities, work context, interests, and work styles without collapsing cognition, affect, and behavior into one dimension; preserve removed Work Values only as versioned legacy content |
-| Occupation-to-construct relations | ADR 0245 deliberately declares relation properties without instance assertions | Persist released source observations with source version, occupation code, element identifier, scale identifier, value, sample/error metadata when supplied, and provenance; never invent or locally normalize a weight |
-| Job-family and job-series semantics | No authoritative employer-specific job architecture is present | Define an organization-neutral import contract that preserves the authorized source hierarchy and distinguishes standard occupation codes from employer job families/series; no label-based binding |
-| Temporal and multilevel interpretation | Static vocabulary only; no person-level inference is asserted | Version valid and transaction time, preserve occupation/organization/unit nesting and multiple membership, and require TEPP or the owning Rust psychometric service before any calibrated temporal or multilevel result |
-| Product consumption | The read model has no persisted semantic-layer consumer or authenticated UI evidence | Add a provenance-bearing API and accessible ontology exploration flow, then verify synthetic Storybook edge states plus authenticated aggregate runtime evidence without exposing identifying records |

-PR #607 first merged as `61fd631c7bb3c57113fd19763c2c43161eeb2824`
-into #606's non-default branch. PR #606 subsequently passed the protected gate,
-so the combined TEPP-consumer and operations-dashboard implementation is now
-on `main`; the still-open TEPP producer PR #237 keeps end-to-end anchor
-acceptance unavailable.
-
-PR #604 was closed unmerged after its exact OIDC repair was composed into #605;
-its green or pending checks are not delivery evidence. PR #482 merged as
-protected-main commit `464ff25002044b9d933c8eefd36c8def7ca0ffd8`
-with package conflict markers, identifying baseline records, and an OIDC
-return-context regression. PR #603 repaired the package/privacy and
-analysis-run transaction defects through protected main at `4f53190b`; the
-OIDC defect remains delivered until #604 or the composed #605 passes the
-protected gate. Protected main is therefore not yet a release candidate.
-
-PR #592 first merged as `3b3af3b4fe9c439354433a43444e05f37ab24ea3`
-into #590's non-default stack base at `2f033ba3`. The complete stack then
-passed the protected gate and #590 merged to `main` as
-`1d1379fc59d9dac6e9c8bfa4812313e3b9e8f3c8`.
-
-PR #521 merged through protected `main` as
-`3797f063b1a7396972a749aa81f23745acccbee1`; it is release evidence and no
-longer part of the open queue. That merge also left a standalone conflict
-marker and duplicated stale tail in `CLAUDE.md`; #594 repaired it through
-protected `main` as `241be2dddf657f854cb8be54fe11d4ef48d37976`.
-
-Protected main now contains the ADR 0109 OIDC return restoration from #605,
-including fragment preservation and storage fallback. The #606 dashboard
-landing must additionally route `?post=` deep links to the Board; that focused
-regression is part of the current candidate and is not delivery evidence yet.
-
-Three systemic gates currently dominate the queue:
-
-1. **Strix visibility lookup failure (org control plane).** PR #600 exact head
-   `7580bdc9` failed before scanning because the required-workflow token could
-   not resolve this public repository after six API retries. The root repair is
-   ContextualWisdomLab/.github#1320 at `3b9b2380`: ordinary PR, push, and
-   schedule runs use trusted event visibility; cross-repository dispatch keeps
-   authoritative public/private/internal visibility; private and internal
-   repositories remain on private-capable providers. The exact head also
-   composes the executable fallback contract and classifies bounded NVIDIA
-   `ServiceUnavailableError` overload evidence as retryable across configured
-   distinct models without weakening exhaustion or vulnerability fail-close.
-   A hosted fallback then completed with zero vulnerabilities but was rejected
-   because the generic warning gate treated Strix's fallback-model banner and
-   a Hugging Face unauthenticated-download notice as provider failures. The
-   current head removes only those two exact scanner notices before the
-   existing general warning and explicit 429/provider failure checks. The
-   current head also clears a foreign NVIDIA/OpenRouter endpoint before a
-   direct-OpenAI fallback while retaining an explicitly configured
-   direct-OpenAI primary endpoint. The prior full quick-gate harness, overload
-   path, 12 visibility-contract tests, and the focused cross-provider endpoint
-   contract passed; exact-head hosted revalidation remains pending. It is blocked on
-   hosted exact-head gates and independent review, so no repaired
-   protected-main Strix runtime evidence exists yet.
-2. **Strix provider unavailability (org control plane).** The central required
-   Strix scan on .github#1320 failed when NVIDIA returned `Service temporarily
-   overloaded`; the gate correctly failed closed but did not try its configured
-   distinct fallbacks because the service-unavailable classifier excluded the
-   NVIDIA provider. Exact head `3b9b2380` composes that execution repair and the
-   two exact non-fatal scanner-notice exclusions while keeping
-   incomplete exhaustion non-passing. This is still an unmerged control-plane
-   proposal, not protected-main or downstream runtime evidence.
-3. **Current-head independent approval.** The org merge scheduler requires
-   `reviewDecision == APPROVED` plus complete Strix evidence on the exact
-   head. Bot review evidence regenerates per push, so any repair push resets
-   the review clock by design; this is expected and not a bypass target.

-This documentation is owned by protected `main` again: the #426 stack landed,
-so hidden-stack merges (#494, #497, #499, #505, #509 into unprotected parent
-branches) are historical context only and no longer gate anything.
-
-The current protected-`main` and exact #507 trees are clean of the private
-runtime source-table identifier present in the closed #506 head and older
-public history. Do not reproduce or hint at its value. Historical remediation
-requires the ADR 0001 incident process and security/privacy-owner coordination;
-never force-push or delete evidence ad hoc.
-
-The Grok durable hourly loop and the central thin GitHub Actions caller
-ContextualWisdomLab/.github#1259 (minute 4, `pr-review-fix-scheduler.yml`)
-both target this repository. Do not add a LineageWeave-local duplicate
-workflow. ContextualWisdomLab/.github#1258 merged at exact head `897819c4` to
-repair the pnpm/coverage-evidence workflow; newly created exact PR heads must
-still prove the runtime behavior because merged workflow source alone is not
-check evidence.
-
-Figma design-system boundary (ADR 0002): File ID `1Su3lDRmiZdcUs47t1QwIX`.
-The sanitized file now contains synthetic Event Lineage desktop (`5:14`) and
-mobile (`5:15`) frames with graph direction, event dates, an inference
-boundary, and exact fused-score evidence. Do not copy source-organization
-content into this repository. Storybook remains the executable scene and
-edge-case inventory for repeated web objects; rendered code-to-Figma parity
-still requires same-viewport browser comparison on an exact candidate head.
-
-## 2. User-visible capability baseline
-
-Substantially present on protected `main`:
-
-- PostgreSQL-backed import, normalized provenance, cutoff-aware analysis runs,
-  source revisions, lineage reconstruction, and explicit unavailable states.
-- Authenticated workspace navigation, post detail, localized summaries, 5W1H,
-  R&R/Keyman, evidence citations, chat, organization hierarchy, and lineage DAG
-  (`frontend/src/LineageDag.tsx` is on `main`; the old “DAG view missing”
-  baseline entry is stale).
-- Semantic paragraph/list/table/image-region units that preserve the source
-  representation and provenance instead of flattening it into one body string.
-- FJA→I/O-Psychology semantic layer (ADR 0251): the published DOT/FJA
-  Data/People/Things worker functions (ADR 0232) project into disjoint
-  cognitive, affective, and behavioral constructs with APA 7th anchors,
-  SHACL validation, and a deterministic typed read model
-  (`lineageweave/iopsy_taxonomy.py`); no fitted weight or O*NET/ADR 0248
-  crosswalk is asserted (ADR 0145).
-- Contextual-orchestrator boundaries for adjudication, extraction, summaries,
-  chat, embeddings, and VISION; null channels remain unavailable and are
-  dropped from score fusion.
-- W3C PROV-O projection through normalized provenance tables, with the
-  knowledge graph retained as an explicit navigation projection.
-- Keyverse/Keycloak OIDC, RankWeave fusion port, TEPP measurement client,
-  ThreadWeave tree assembly.
-
-These statements describe source capability, not authenticated production
-corpus acceptance or protected release.
-
-## 3. Historical open-PR inventory (superseded by §1)
-
-Heads below are queue evidence captured at snapshot time; recheck SHA,
-checks, unresolved threads, and independent approval immediately before any
-merge claim. Do not self-approve, force-push, or transfer stale review
-evidence across heads. The org merge scheduler merges only when
-`reviewDecision == APPROVED` on the exact head and Strix evidence is complete.

-### 3.0 Shared systemic gate
-
-| Gate | Evidence | Durable repair |
-| --- | --- | --- |
-| Strix provider unavailability | `nvidia_nim/nvidia/nemotron-3-super-120b-a12b` and `openai-direct/gpt-5.6-luna` failed authoritatively across unrelated heads | ContextualWisdomLab/.github#1263 at `ab3d7645` proposes executable Azure/cross-provider fallbacks but remains open/conflicting; repair that branch without weakening the required gate |
-| ADR 0109 login repair debt | Eight branches cut from the pre-repair base carried the unauthenticated `AdminPanel` + unused-OIDC-helper `tsc -b` failure | Same verified two-line repair applied to #521, #522, #552, #553, #554, #556, #558, #560 during this loop; frontend lint/test/build verified locally |

-## 4. Open issues (complete live queue; product acceptance remaining on `main`)
-
-| Issue | User-visible gap | Active PR |
-| ---: | --- | --- |
-| #79 | Milestone 2: port verified direct-PostgreSQL analysis into the protected architecture | analysis-run registry on `main`; remaining runtime bridge |
-| #87 | Milestone 2.1 normalized runtime-analysis schema bridge | related analysis-run work |
-| #269 | Authenticated Global Ask MCP browser-safe and admission-bounded | Ask stack |
-| #271 | Evidence-honest knowledge-cutoff scope on Global Ask | #658; still open and not protected-main evidence |
-| #272 | Verify Global Ask KG/ontology/semantic claims with public SearXNG evidence | #632 preserves internal provenance; public verification acceptance remains open |
-| #277 | TEPP: persist accepted receipts, poll completed results, keep measurement authority distinct | #657 consumer lifecycle; executable producer route remains unavailable |
-| #280 | Full project-lifecycle history and handover intervals | #640 adds case/project journeys and #663 adds evidence-backed Project exploration; authoritative lifecycle reconciliation remains #284 |
-| #284 | Authoritative lifecycle ingestion and idempotent reconciliation | No active delivery PR confirmed |
-| #338 | Evidence-bounded email/project lineage contract for Naruon consumption | #704 recreates the provider-side contract on current `main` without arbitrary fusion weights; #343 remains only a non-default-stack merge and #355 is a distinct calendar contract |
-| #611 | Decompose closed PR #490 ADR 0133–0137 evidence without transferring stale branch state | #631 supplies the current-main inventory only; focused implementation PRs and tests for every unmet criterion are still required |
-
-## 5. Open product and technical gaps
-
-| Gap | Current evidence | Acceptance requirement |
-| --- | --- | --- |
-| Protected release | 12 open PRs at snapshot, all targeting `main` with normal auto-merge enabled. None has the required independent approval, and running checks on #631/#632/#663 are not treated as blockers for safe work on other PRs. #666's merge into the non-default #663 branch is not protected-main delivery | Terminal exact-head checks, no unresolved threads, two independent approvals including last-push approval, protected squash-merge SHA |
-| CI queue release latency | Two Tests runs for already merged PRs occupied the available runner slots while 54 newer runs remained queued. Manual cancellation released the stale work, but the central close workflow was itself queued behind those runs. #634 merged into #631's non-default branch and reuses the repository's existing per-PR concurrency group so a jobless close event can cancel obsolete Tests work before runner allocation; this is not protected-main delivery | Merge #631 through its refreshed protected gate; close a synthetic PR while its Tests run is active and verify the old run becomes cancelled, the close-event jobs remain skipped, and a newer exact-head run starts without manual intervention |
-| Evidence-grounded operations workspace | Protected-main #614 delivers governed semantic Ask, live Similar VOC, disjoint pending/failed analysis metrics, full Storybook state inventory, and current desktop/mobile screenshot evidence. Authorized-corpus backfill acceptance remains unavailable | Perform authenticated authorized-corpus acceptance with aggregate evidence and retain fail-closed no-match behavior |
-| Shared frontend gate | The ADR 0109 login repair is on protected `main`; eight older branches carried the defect and received the same verified repair this loop (#521–#560) | Keep every future branch cut from post-repair bases; re-verify with frontend lint/test/build before push |
-| Identifying baseline regression | `main` gap file listed real post identifiers; separately, closed #506 and pre-existing public history contain a private runtime source-table identifier, while current `main` and #507 trees are clean | Land this non-identifying rewrite, then coordinate ADR 0001 history remediation with security/privacy owners; do not reproduce the value, force-push, or delete evidence ad hoc |
-| Authorized-corpus runtime | Repository tests use synthetic fixtures; private records remain outside git | Authenticated runtime validation returning only aggregate, non-identifying evidence |
-| Concurrent web responsiveness | ADR 0204 releases pooled transactions during provider work, and the synthetic Compose boundary has an authenticated k6 E2E harness for Ask enqueue, concurrent reads, and job polling. PR #633's measured landing-query and event-loop work merged into open parent #629 rather than protected `main`; its aggregate observation improved 25-VU throughput but did not establish a latency SLO. The current exact #629 also persists each completed relation verification before propagating a later provider failure | Land #629 through its refreshed protected gate, rebuild that exact-head application image, and repeat `make load-http` with declared environment concurrency/window and retained raw distributions/resource configuration; set no SLO until representative capacity evidence is approved |
-| Image understanding | Region, OCR, and description work exists across active heads (#405, #419), but current runtime acceptance has not yet proved table-image structure, complete region coverage, or summary/image readiness together | Orchestrator-backed rendered workflow, original/derived asset provenance, region-before-OCR processing, and honest unsupported states; reconcile ADR 0052's image-bearing summary readiness with ADR 0098 before changing sequencing |
-| Semantic source rendering | Paragraph, table, list, formula, and indentation work exists across stacks (#394, #427, #448–#450); #515 adds synthetic backend/frontend parity for deterministic rows/cells, footnote boundaries, and encoded scripts | Land the #427 → #515 stack, then gather authenticated browser evidence that list nesting, continuation alignment, and formula units render without authoring-layout artifacts |
-| Event and project semantics | #663 is the largest current user-visible gap slice: evidence-backed Project nodes, bounded traversal, cutoff/snapshot fencing, exact-value table parity, and localized graph labels. Focus visibility, label-bound, and temporal test-double regressions are repaired. #666's heuristic removal is composed into this parent but is not separately protected-main evidence. #640 separately adds project journeys without claiming authoritative lifecycle status | Combined #663 must pass exact-head checks and independent approval before protected merge. Aggregate authenticated evidence must still prove distinct projects/events and handover intervals without promoting co-occurrence |
-| Voice primary history | Protected `main` `bbb19192` includes ADR 0252 / #761 (migration 0243, GiST primary-period exclusion, `clock_timestamp()` after the source-row lock, API/ontology half-open cutoff SQL). v2.22.1 adds synthetic PostgreSQL integration tests for A → B → A at before/between/after cutoffs, concurrent primary updates, additional-assignment close, and 0237→0243 trigger replay. This is not yet protected-main evidence | Land the live-test slice through the protected gate with independent exact-head APPROVE; close #748 only after that protected delivery |
-| Knowledge Graph readability | #659 recreates the token-backed node-type repair on current `main`, including regression coverage; it is open and therefore not protected-main evidence | Merge #659 normally, then verify light/dark contrast, keyboard graph navigation, full labels, and evidence tables in the authenticated rendered surface |
-| Source-code lookup UX | Source state/detail codes remain evidence-bearing machine values and current detail presentation is dense | Catalog-backed display labels with raw-code provenance, compact 5W1H/source-detail hierarchy, keyboard access, and no unsupported customer/project binding |
-| Calendar / Naruon | #355 delivered the projection contract; v2.17.0 wires operator consumption without forwarding the end-user token. Naruon producer, provider/consumer fixtures, and protected merge remain open (#336) | Verify observed events against the published schema without invented events; keep commitments available when the channel is unwired |
-| SKOS organization aliases | Catalog binding and chip caption live on #480 / #482 | One catalog row per corroborated org; companion caption is hint-only until bound |
-| Event Lineage evidence | Channel evidence and Allen relations live on #387 / #484 | Persist channel scores, explain them in the popup, never invent a fused score |
-| Scientific measurement | Durable accepted TEPP receipts and LineageWeave #614's exact accepted snapshot/cutoff/run/pair-count consumer are protected; TEPP #237 remains open, so no registered producer artifact exists yet. #387 removes inferred/default persistence weights, but several older reconstruction tests still pass hand-authored numeric dictionaries that are not estimator evidence | Land TEPP #237 through its protected gate, then replace remaining reconstruction-test constants with provenance-bearing fast-mlsirm estimates over synthetic fixtures. Retain true-parameter RMSE recovery as the acceptance bar |
-| Asynchronous authorization | Protected `main` rebuilds Global Ask worker scope after the bearer token leaves the request; #468 now persists exact Keyverse organization/process-unit scope in 3NF child tables and intersects it with current affiliations | Land #468 through the protected gate; prove a second affiliation and a revoked process unit cannot widen delayed-job evidence |
-| Planned-facility intent | Planned-facility relationship intent remains only on closed, unmerged #490; earlier stack-only merges were not protected delivery | Recreate the evidence-backed slice on a current base and land through protected `main` before a release claim |
-| Accessibility and responsive UX | #602 delivered base post-detail modal semantics; #605 adds selected-post refocus, collapsed/hidden/inert/CSS-invisible focus exclusion across both modal types, readable evidence separators, focused tests, and desktop/mobile Storybook screenshots | Land #605 through the protected gate, then complete screen-reader and authenticated Playwright acceptance on the exact release head |
-| Design tokens and repeated objects | Token extraction started; sanitized Figma Event Lineage desktop/mobile frames exist, while other repeated product surfaces remain incomplete | Tokens in CSS + Storybook stories for board, popup, DAG, Ask, calendar, forms, charts; same-viewport Figma/runtime visual comparison before release |
-| Frontend delivery performance | #644 implements a native dynamic-import boundary for conditional workspace surfaces and retains accessible loading/error states; exact-head checks passed but the PR is not protected-main evidence | Merge #644 normally, rebuild the protected-main production bundle, and retain the measured chunk inventory rather than raising the warning limit |
-| External integrations | Search, Zotero, calendar, Keyverse, orchestrator, RankWeave, ThreadWeave, TEPP, DiskSage, wardnet | Provider conformance, failure/reconciliation behavior, and provenance-bearing integration evidence |
-| Naruon email/project lineage | #704 provides a strict store-agnostic v1 contract, opaque evidence references, observed/inferred truth separation, knowledge-cutoff admission, and explicit unavailable states. Inferred edges require an injected provenance-bearing fast-mlsirm estimate; no local default weight exists | Merge #704 through protected `main`, publish an immutable attested artifact, then enable the Naruon consumer only against that released version and its contract fixtures |
-| MSA / modular reuse | LineageWeave must run standalone and as a consumer of org packages | Do not reimplement RankWeave/TEPP/orchestrator/ThreadWeave/Keyverse; fix upstream and PR there |
-| Accelerator runtime ownership | ADR 0076/0208 already prohibit local model and mathematical ownership; ADR 0237 now defines MLX as a native orchestrator-side service and TEPP/fast-mlsirm CUDA/OpenCL/CPU profiles as scientific-compute-owner deployments, so LineageWeave Compose remains device-neutral. RankWeave remains the dependency-free Python retrieval-fusion/evaluation owner behind its published contract | TEPP and fast-mlsirm must publish deterministic CPU recovery plus conformance evidence for every advertised CUDA/OpenCL profile; contextual-orchestrator must prove native MLX availability through its provider-neutral health/contract boundary. LineageWeave accepts only versioned, provenance-bearing envelopes and fails closed when the owner is unavailable |
-| Product contract authority | The current LineageWeave PRD records exact-case ecosystem authorities. TEPP, fast-mlsirm, keyverse, ThreadWeave, and RankWeave PR #41 have standalone PRDs; RankWeave's remains unmerged. contextual-orchestrator, disksage, and wardnet still rely on product/architecture documents, and naruon has only a scoped Topic Intelligence PRD | Keep ADRs normative, preserve canonical repository case in machine references, land the pending PRDs, and add standalone PRDs in each remaining owning repository before cross-product release claims exceed its documented boundary |
-| Release quality | PR #660 is now on protected `main`; its pre-merge full Python suite passed 1,352 tests with 17 skips, but release-wide frontend, Storybook, security, browser, and runtime acceptance remain unproven on one exact protected head | Repository-wide coverage, docstrings, Storybook, security, browser, and release evidence on one exact head |
-| PII | Masking would paralyze the product; ADR 0001 forbids identifying artifacts in git | ABAC + authorized runtime; synthetic fixtures in git; no mask-in-place that drops names the operator must read |
-| Database | PostgreSQL, 3NF, snake_case ≥ two words, hot-partition and lock policy | No file DBs; read/write split if lock management fails; whitelist every migration |

-### 5.1 Closed PR #490 decomposition (issue #611)
-
-Protected `main` at `04e6b610` and the three open PRs present during the initial
-decomposition were rechecked; the later audit snapshot above includes #631
-itself as the fourth open PR. Protected `main` contains none of PR #490. That PR remains
-closed, unmerged branch evidence; its ADR 0133–0137 files are not normative and
-its 321-file tree must not be replayed. Current-main code and schema searches
-give this delivery matrix:
-
-| Closed-branch decision | Current-main classification | Smallest remaining delivery |
-| --- | --- | --- |
-| ADR 0133 source-reference research | Partial foundation: protected `main` has the self-hosted SearXNG relation-verification client and fail-closed configuration, but it verifies an already extracted relation.

-## 7. Ecosystem leverage order
-
-Reuse before rebuild. Consume these ContextualWisdomLab packages in this order
-of leverage; open connector PRs there when the defect is upstream:
-
-1. **contextual-orchestrator** — every LLM/VISION/embedding call (Fugu / Conductor / TRINITY routing). Never a raw provider SDK.
-2. **Keyverse** — OIDC issuer, JWKS, tenant principals.
-3. **RankWeave** — fused scores and rankings; never invent a fused score or theta.
-4. **TEPP** — calibrated measurement; persist receipts; no local reimplementation.
-5. **fast-mlsirm** — GRM/GPCM/CAT/FIPC recovery tests (#451–#454) must stay true-parameter RMSE.
-6. **ThreadWeave** — tree assembly.
-7. **Naruon** — calendar and email/project lineage projection (#336, #338, #355).
-8. **DiskSage / wardnet** — storage and network policy as needed.
-9. **ContextualWisdomLab/.github** — required review workflows (OpenCode, Strix, Noema) and the LineageWeave hourly caller (#1259). If stacked PRs miss central review or coverage-evidence fails on pnpm 9 (`--trust-lockfile` is pnpm 11.3) or a missing Vitest coverage provider, fix the org workflow (#1258), not a local bypass.
-
-## 8. Public ontology publication boundary
-
-- PR #426 publishes fragment-addressable HTML, byte-identical Turtle,
-  isomorphic JSON-LD and N-Triples, the PROV-O support profile, and a
-  source-digest manifest from the authoritative ontology.
-- Pull requests validate only. Only protected `main` may publish, and the
-  generated-directory marker, linked-IRI, duplicate-fragment, symlink, and
-  source-overlap checks fail closed.
-- The lowercase knowledge-graph namespace and repository-case support-profile
-  namespace remain distinct until issue #372 delivers a versioned migration
-  and compatibility decision; this publication PR rewrites neither identity.
-- Until the protected deployment and exact URL checks succeed, the public
-  ontology endpoint remains unavailable and must not be represented as live.
-
-## 9. Evidence boundaries
-
-- Never add a real record, title, name, identifier, screenshot, log, benchmark
-  artifact, or documentation example to this repository.
-- Attendance or co-occurrence is not responsibility, project, customer, or
-  affiliation evidence. Preserve uncertainty and provenance.
-- Missing transport, model capability, accepted envelope, or persistence is
-  unavailable or failed evidence, never a placeholder result.
-- Local green tests, bot statuses, auto-merge, and warning-only checks do not
-  prove a protected merge.
-- Re-fetch base/head SHAs, checks, review threads, approvals, rulesets, and the
-  merge SHA immediately before any lifecycle claim.
-- Do not self-approve. Independent OpenCode / Strix / Noema review is required.
-- Do not force-push. Do not treat GitHub Checks duration as a blocker; repair
-  the failing check instead.
-- `COPILOT_GITHUB_TOKEN` is not used.
-
-## 10. Next acceptance loop (autonomous merge order)
-
-Process every open PR in ascending number order, considering leverage; for
-each: check reviews → repair → re-verify Checks → merge → continue. Checks and
-review latency are never blockers — keep working while they settle.
-
-1. Revalidate Strix after merged ContextualWisdomLab/.github#1320, reconcile
-   open .github#1263, and land the atomic hourly LineageWeave caller in open
-   .github#1288 only through their protected gates.
-2. Process main-targeted PRs #629, #631, #632, #639, #640, #643, #644, #657,
-   #658, #659, #660, and #663 only after each exact head shows terminal green
-   required checks plus current-head independent approval. Treat #666's
-   non-default-branch merge only as part of #663's combined candidate and
-   collect all protected evidence on #663's exact head.
-3. While hosted checks or independent reviews wait, resume user-visible gaps
-   from §5 in leverage order:
-   external semantic verification (#272), Naruon calendar (#355/#336), and
-   authenticated operations/ontology publication acceptance. Event Lineage
-   evidence shipped in merged PR #387 and closed issue #274 is not an open gap.
-4. Rename remaining `[Buyer Gap]` issue titles to neutral product-object
-   naming per repository convention (no "Buyer" for internal objects).
-5. Keep psychometric tests as true-parameter recovery (RMSE); never fixture
-   tautologies, invented theta, or hand-authored numeric weights. Remove
-   weights from tests that do not exercise fusion; fusion tests must consume
-   provenance-bearing fast-mlsirm estimates over synthetic fixtures.
-6. Run frontend lint/test/build/Storybook, backend tests, and authenticated
-   browser/accessibility checks on the exact candidate release head.
-7. Fix only evidence-backed failures and repeat the protected merge gate.
-8. Refresh this file each loop with the exact queue state.

+
+## Current implementation boundary
+
+- ADR 0362 remains **Proposed**. PostgreSQL is authoritative for versioned UI
+  translation resources, required screen keys, and localized text; Valkey is
+  only an exact immutable-version read cache.
+- Migrations `0246_ui_translation_ledger.sql` and
+  `0247_ui_translation_truncate_guard.sql` define the normalized ledger,
+  publication immutability, eight-locale completeness, writer serialization,
+  statement-level TRUNCATE protection, and replay/fail-closed rollback path.
+- `backend/app/translation_ledger.py` admits exactly
+  `ko/en/ja/zh/vi/es/de/fr`, returns immutable `TranslationScreen` value
+  projections, validates canonical PostgreSQL text/BIGINT identities, admits
+  cache hits only after PostgreSQL key-set and SHA-256 value evidence, performs
+  no cross-locale fallback, and releases the PostgreSQL lease before optional
+  Valkey I/O.
+- `GET /api/translations/{screen_key}` is authenticated and propagates exact
+  screen/locale/version identity. Missing published resources map to 404;
+  incomplete requested-locale copy maps to 409; unsupported admission maps to
+  422.
+- Focused HTTP and asyncpg-boundary tests cover the route without adding a
+  direct `psycopg2` caller. The documentation-alignment contract prevents this
+  baseline from regressing to the obsolete claim that the API does not exist.
+- None of the above is release evidence until the unchanged exact PR head has
+  terminal required/security checks and qualifying independent approval, then
+  reaches protected `main` normally.
+
+## Next buyer cut
+
+1. Use reviewed product copy to create and publish one complete screen resource
+   for all eight locales. Do not invent copy to satisfy coverage.
+2. Cut one material SPA screen off bundled `TRANSLATIONS` and onto the versioned
+   API. Customer Master is the natural first slice because #922 gates its open
+   material-UI work, but the screen identity must follow the actual product
+   composition contract rather than creating a second domain owner.
+3. Prove normal/loading/empty/error/permission/responsive states plus
+   keyboard/focus/screen-reader behavior, CJK rendering, text expansion, and
+   font fallback on the same exact head with fresh desktop and mobile evidence.
+4. Converge PRD/TRD/ARCHITECTURE/UX/OPERABILITY/TEST_STRATEGY/CHANGELOG and this
+   baseline with the actual cutover. Keep ontology labels separate from product
+   copy and consume only released owner contracts where another CWL product is
+   authoritative.
+5. Keep #929 Draft and do not merge, bypass, or release until exact-head gates
+   and independent review are complete.
+
+## Traceability
+
+- Product gap: issue #922, `i18n: move UI translations to versioned DB ledger
+  and complete 8-locale coverage`.
+- Decision: `docs/adr/0362-versioned-ui-translation-ledger.md`.
+- Persistence: `migrations/0246_ui_translation_ledger.sql`,
+  `migrations/0247_ui_translation_truncate_guard.sql`, and their rollback
+  artifacts.
+- Read model: `backend/app/translation_ledger.py`.
+- HTTP boundary: `backend/app/main.py` (`GET /api/translations/{screen_key}`).
+- Verification: `tests/test_translation_ledger_*`,
+  `tests/test_translation_screen_value_object.py`,
+  `tests/test_translation_api_http.py`,
+  `tests/test_translation_api_driver_boundary.py`, and
+  `tests/test_translation_documentation_alignment.py`.

-## Voice-of-X product and technical gap
-
-ADR 0246 and PR #713 add Supplier, Employee, Business, Regulator, Investor,
-Society, and Process to the original Customer, Customer's Customer,
-Competitor, Market, and Partner source-post vocabulary. The migration,
-published SKOS concepts, product requirements, changelog, and ontology
-round-trip tests agree on the twelve codes. The design is organization-type
-neutral: public bodies, nonprofits, communities, and automated processes do
-not need to be forced into a B2B2C customer chain.
-
-The phrase "all Voice-of-X combinations" does not have a standards-backed
-finite enumeration. ISO's own stakeholder-category guidance says that the
-relevant category set varies by committee and subject; ISO 26000 requires
-stakeholder identification and engagement across organizational contexts;
-AA1000SES requires an inclusive, continuing identification process; and
-Mitchell, Agle, and Wood (1997) model stakeholder salience from combinations
-of power, legitimacy, and urgency rather than a fixed industry-role list.
-Accordingly, ADR 0246 keeps the controlled vocabulary extensible and refuses
-keyword inference, defaults, invented weights, or an asserted exhaustive
-cross-product.
-
-ADR 0256 and migration 0237 now define the persistence contract for
-evidence-bearing composition. A post keeps one source-provided
-`voc_type_code`, mirrored as its sole primary association, while every
-additional voice requires a normalized PROV-O assertion and explicit truth
-status. Half-open assignment intervals preserve a backfilled primary at
-historical cutoffs, close a replaced primary without deleting it, and permit a
-later return to the same Voice. The #717 candidate therefore addresses #748's
-A → B → A storage root cause without adding Cartesian-product codes. Protected
-delivery and synthetic PostgreSQL concurrency/cutoff evidence remain required.
-The remaining acceptance boundary is:
-
-1. preserve the imported primary voice without reclassification (implemented
-   in the candidate migration; migration 0237 replayed twice successfully on
-   an isolated PostgreSQL stack on 2026-08-27, including both primary-sync
-   triggers; a synthetic real-OIDC PostgreSQL API write also proved that the
-   imported primary remains unchanged);
-2. record each additional voice with its own source/evidence and truth state
-   (schema-enforced and candidate `post_admin` API plus live Post-popup
-   authoring implemented; synthetic authenticated PostgreSQL integration
-   proved denial before permission, the authorized write, and its normalized
-   PROV-O derivation on 2026-08-27);
-3. keeps post voice distinct from named-counterparty relationship, actor role,
-   topic, channel, lifecycle, and stakeholder-salience attributes;
-4. return only authorized associations through API, JSON-LD, CSV, filters,
-   and UI (candidate API list/detail, filters, combined post-card labels,
-   qualified JSON-LD, exact-value CSV, SHACL, and source-post evidence
-   navigation implemented; the board re-filter matches every associated voice
-   and all twelve governed atomic labels are localized across English, Korean,
-   Chinese, Japanese, and Vietnamese; one bounded query projects assignments
-   for every authorized Post even when another node type is the focus; post
-   detail lists primary and evidence-connected perspectives separately and
-   honors its knowledge cutoff; client-side JSON-LD filtering retains only
-   exact canonical repository-case node and Voice-assignment IRIs rather than
-   accepting cross-origin suffix matches; the exact-value row exposes distinct
-   carrying-Post and authorized derivation-evidence actions, while hidden
-   evidence emits neither an identifier nor a fabricated evidence count;
-   paged JSON-LD merges properties for one subject and unions its multi-Voice
-   relation rather than overwriting an earlier page); and
-5. proves zero-, one-, and multi-voice states with synthetic fixtures,
-   migration replay, ontology/SHACL, API, accessibility, and Storybook edge
-   tests before any release claim. The candidate `CombinedVoiceEvidence` scene
-   covers primary-plus-additional assignments; desktop and mobile screenshots
-   were inspected on 2026-08-27. At 390 CSS pixels the document did not
-   overflow, the named exact-value region remained horizontally scrollable,
-   and the source-post evidence action remained visible and labeled. The
-   `Post/Recorded perspectives` desktop and 390-pixel scenes were also inspected
-   on 2026-08-27; both kept each complete Voice label paired with its imported
-   or evidence-connected state without clipping or horizontal overflow. The
-   `Post/Connect perspective` ready/success scenes were inspected at 1440 and
-   390 CSS pixels on 2026-08-27: labels stay above controls, the mobile form is
-   a single column, controls meet the 44-pixel touch target, and no horizontal
-   overflow was visible.
-
-At this snapshot the repository had 42 open PRs and 11 open issues. PR #713
-head `850494c3` includes the review-driven localization of all twelve governed
-Voice labels. Its frontend, ontology publication, static-analysis, dependency,
-coverage, full-suite, CodeRabbit, Devin, and OpenCode checks passed. Strix
-failed closed before producing a vulnerability report:
-the primary NVIDIA NIM model returned HTTP 429, one configured fallback had
-reached end of life, and the OpenAI fallback reported exhausted credits. A
-same-head retry completed on 2026-08-27 with the explicit
-`STRIX_PROVIDER_UNAVAILABLE` annotation and again produced no vulnerability
-report. This
-is provider/control-plane unavailability, not a vulnerability result or
-permission to transfer an older success. Auto-merge remains enabled, while an
-independent approval is still required. PR #717 implementation head
-`d5fe4828` merges that
-parent change without force-pushing and separates the complete governed Voice
-catalog used for authoring from usage-derived Board filters, so an authorized
-administrator can attach a Voice that no visible Post carries yet. It also
-labels Voice exact-value navigation as opening the carrying Post rather than
-misrepresenting that Post as the separately recorded derivation evidence. Its
-CodeRabbit and hosted Frontend/Storybook checks passed at predecessor head
-`ebb4ef1d`; refreshed checks for exact head `d5fe4828` were queued. Focused local
-backend tests, frontend type checking/lint, and the new unused-Voice authoring
-regression passed, and the exact-value navigation tests, lint, and type check
-passed after the label repair. The paged JSON-LD union regression and Voice
-evidence navigation suite passed 23 focused frontend tests; 48 focused backend
-ontology/docstring tests also passed. The full backend suite at predecessor
-head `ebb4ef1d` passed 1,366 tests with 148 environment-dependent skips. The
-real-integration fixture now applies
-the existing migration 0042 before the expanded taxonomy migrations instead
-of seeding an incomplete or duplicate legacy catalog; the exact
-`d5fe4828` authenticated post-list integration passed in 91.54 seconds. The
-wider local frontend run had 400 passes and eight five-second timeouts under
-concurrent backend-suite load; a later App-only run had 94 passes and five
-five-second timeouts, while the hosted Frontend/Storybook job passed on
-`ebb4ef1d`. Neither local timeout run is promoted to full-suite success. An initial
-authenticated integration attempt was unavailable while Keycloak initialized;
-a later retry against the shared synthetic stack succeeded in 56.18 seconds
-and proved the permission, API, PostgreSQL,
-PROV-O, and primary-preservation assertions; no identifying source data was
-used or retained. No self-approval, admin bypass, or stale-head check transfer
-is permitted.
-
-Stacked PR #717 carries ADR 0256, migration 0237, qualified
-ontology terms, persistence/API/UI tests, and the category-validation review
-repairs plus a local candidate admin write path that creates its PROV-O
-derivation from an authorized evidence Post. Its JSON-LD projection names that
-evidence Post only when it is in the authorized visible set and omits the whole
-additional assignment otherwise, preserving the SHACL evidence minimum without
-substituting the assigned Post. It targets
-#713's branch, not protected `main`;
-its checks and review are candidate evidence only. After
-#713 reaches protected main, #717 must be synchronized, retargeted to `main`,
-and revalidated on its then-current head.
-
-Downstream Dashboard repair PR #737 exact head `a837ee5d` is stacked on base
-`7c7bb2cf`, which contains migration 0235 through a non-#713 composition but
-does not contain #713's twelve-label locale update. Its added Voice labels are
-therefore necessary on that exact base, yet overlap #713 and must be reconciled
-when the stack is eventually rebuilt on protected `main`; neither branch is a
-second taxonomy authority, and pre-parent Checks cannot transfer across that
-restack.
-The remaining user-visible gap is evidence-bearing composition. A post still
-has one source-provided `voc_type_code`; the product cannot yet represent a
-single record that intentionally carries multiple independently evidenced
-voices, nor expose the combination in filters, exports, or the ontology
-neighborhood. Do not solve this by adding every Cartesian-product code. The
-acceptance boundary for a later ADR is a normalized, provenance-bearing
-multi-voice association that:
-
-1. preserves the imported primary voice without reclassification;
-2. records each additional voice with its own source/evidence and truth state;
-3. keeps post voice distinct from named-counterparty relationship, actor role,
-   topic, channel, lifecycle, and stakeholder-salience attributes;
-4. returns only authorized associations through API, JSON-LD, CSV, filters,
-   and UI; and
-5. proves zero-, one-, and multi-voice states with synthetic fixtures,
-   migration replay, ontology/SHACL, API, accessibility, and Storybook edge
-   tests before any release claim.
-
-At this snapshot the repository had 23 open PRs and 10 open issues. PR #713
-was `MERGEABLE` but policy-blocked: exact-head backend, frontend, CodeQL,
-ontology-publication, Semgrep, OSV, Trivy, Scorecard, Noema, Devin, and
-CodeRabbit checks were successful; `coverage-source-tree` was queued; Strix
-failed closed with `STRIX_PROVIDER_UNAVAILABLE`; and an independent approval
-was still required. Auto-merge remains enabled. No self-approval, admin bypass,
-or stale-head check transfer is permitted.
-
-References for this gap use the APA 7 entries in ADR 0246. Current supporting
-standards pages were rechecked on 2026-08-27: ISO 26000:2010 remains applicable
-to all organization types and AA1000SES v3 is under development for a planned
-2027 release, so the repository continues to cite the published AA1000SES
-(2015) contract rather than treating the draft as adopted policy.

-## Current occupational semantic-layer gap
-
-ADR 0245's candidate branch publishes only a provenance-safe classification
-foundation: 23 2018 SOC major groups, four O*NET 31.0 Job Zone categories, six RIASEC interest
-types and their published adjacency, six explicitly legacy work-value clusters, seven
-revised work-style dimensions, and four ability domains. It asserts no
-occupation-to-characteristic instance profile and therefore does **not** yet
-satisfy the requested job-family, job-series, and occupation-level coverage of
-work cognition, affect, behavior, or their empirical relations. This is an
-explicit unavailable state, not a reason to infer mappings from labels.
-
-| Gap | Current evidence | Acceptance requirement |
-|---|---|---|
-| Classification depth | ADR 0245 and `lineageweave/io_taxonomy.py` expose SOC major groups only; schemes now name versioned PROV source entities and the stable O*NET 31.0 Job Zone JSON digest | Import a versioned authoritative classification release with provenance-preserving major, minor, broad, and detailed occupation identifiers; add ISCO/ESCO crosswalks only where the publishing authority supplies them |
-| Construct granularity | The candidate ontology exposes 23 high-level characteristic concepts | Publish source-versioned O*NET abilities, skills, knowledge, work activities, work context, interests, and work styles without collapsing cognition, affect, and behavior into one dimension; preserve removed Work Values only as versioned legacy content |
-| Occupation-to-construct relations | ADR 0245 deliberately declares relation properties without instance assertions | Persist released source observations with source version, occupation code, element identifier, scale identifier, value, sample/error metadata when supplied, and provenance; never invent or locally normalize a weight |
-| Job-family and job-series semantics | No authoritative employer-specific job architecture is present | Define an organization-neutral import contract that preserves the authorized source hierarchy and distinguishes standard occupation codes from employer job families/series; no label-based binding |
-| Temporal and multilevel interpretation | Static vocabulary only; no person-level inference is asserted | Version valid and transaction time, preserve occupation/organization/unit nesting and multiple membership, and require TEPP or the owning Rust psychometric service before any calibrated temporal or multilevel result |
-| Product consumption | The read model has no persisted semantic-layer consumer or authenticated UI evidence | Add a provenance-bearing API and accessible ontology exploration flow, then verify synthetic Storybook edge states plus authenticated aggregate runtime evidence without exposing identifying records |

-PR #607 first merged as `61fd631c7bb3c57113fd19763c2c43161eeb2824`
-into #606's non-default branch. PR #606 subsequently passed the protected gate,
-so the combined TEPP-consumer and operations-dashboard implementation is now
-on `main`; the still-open TEPP producer PR #237 keeps end-to-end anchor
-acceptance unavailable.
-
-PR #604 was closed unmerged after its exact OIDC repair was composed into #605;
-its green or pending checks are not delivery evidence. PR #482 merged as
-protected-main commit `464ff25002044b9d933c8eefd36c8def7ca0ffd8`
-with package conflict markers, identifying baseline records, and an OIDC
-return-context regression. PR #603 repaired the package/privacy and
-analysis-run transaction defects through protected main at `4f53190b`; the
-OIDC defect remains delivered until #604 or the composed #605 passes the
-protected gate. Protected main is therefore not yet a release candidate.
-
-PR #592 first merged as `3b3af3b4fe9c439354433a43444e05f37ab24ea3`
-into #590's non-default stack base at `2f033ba3`. The complete stack then
-passed the protected gate and #590 merged to `main` as
-`1d1379fc59d9dac6e9c8bfa4812313e3b9e8f3c8`.
-
-PR #521 merged through protected `main` as
-`3797f063b1a7396972a749aa81f23745acccbee1`; it is release evidence and no
-longer part of the open queue. That merge also left a standalone conflict
-marker and duplicated stale tail in `CLAUDE.md`; #594 repaired it through
-protected `main` as `241be2dddf657f854cb8be54fe11d4ef48d37976`.
-
-Protected main now contains the ADR 0109 OIDC return restoration from #605,
-including fragment preservation and storage fallback. The #606 dashboard
-landing must additionally route `?post=` deep links to the Board; that focused
-regression is part of the current candidate and is not delivery evidence yet.
-
-Three systemic gates currently dominate the queue:
-
-1. **Strix visibility lookup failure (org control plane).** PR #600 exact head
-   `7580bdc9` failed before scanning because the required-workflow token could
-   not resolve this public repository after six API retries. The root repair is
-   ContextualWisdomLab/.github#1320 at `3b9b2380`: ordinary PR, push, and
-   schedule runs use trusted event visibility; cross-repository dispatch keeps
-   authoritative public/private/internal visibility; private and internal
-   repositories remain on private-capable providers. The exact head also
-   composes the executable fallback contract and classifies bounded NVIDIA
-   `ServiceUnavailableError` overload evidence as retryable across configured
-   distinct models without weakening exhaustion or vulnerability fail-close.
-   A hosted fallback then completed with zero vulnerabilities but was rejected
-   because the generic warning gate treated Strix's fallback-model banner and
-   a Hugging Face unauthenticated-download notice as provider failures. The
-   current head removes only those two exact scanner notices before the
-   existing general warning and explicit 429/provider failure checks. The
-   current head also clears a foreign NVIDIA/OpenRouter endpoint before a
-   direct-OpenAI fallback while retaining an explicitly configured
-   direct-OpenAI primary endpoint. The prior full quick-gate harness, overload
-   path, 12 visibility-contract tests, and the focused cross-provider endpoint
-   contract passed; exact-head hosted revalidation remains pending. It is blocked on
-   hosted exact-head gates and independent review, so no repaired
-   protected-main Strix runtime evidence exists yet.
-2. **Strix provider unavailability (org control plane).** The central required
-   Strix scan on .github#1320 failed when NVIDIA returned `Service temporarily
-   overloaded`; the gate correctly failed closed but did not try its configured
-   distinct fallbacks because the service-unavailable classifier excluded the
-   NVIDIA provider. Exact head `3b9b2380` composes that execution repair and the
-   two exact non-fatal scanner-notice exclusions while keeping
-   incomplete exhaustion non-passing. This is still an unmerged control-plane
-   proposal, not protected-main or downstream runtime evidence.
-3. **Current-head independent approval.** The org merge scheduler requires
-   `reviewDecision == APPROVED` plus complete Strix evidence on the exact
-   head. Bot review evidence regenerates per push, so any repair push resets
-   the review clock by design; this is expected and not a bypass target.

-This documentation is owned by protected `main` again: the #426 stack landed,
-so hidden-stack merges (#494, #497, #499, #505, #509 into unprotected parent
-branches) are historical context only and no longer gate anything.
-
-The current protected-`main` and exact #507 trees are clean of the private
-runtime source-table identifier present in the closed #506 head and older
-public history. Do not reproduce or hint at its value. Historical remediation
-requires the ADR 0001 incident process and security/privacy-owner coordination;
-never force-push or delete evidence ad hoc.
-
-The Grok durable hourly loop and the central thin GitHub Actions caller
-ContextualWisdomLab/.github#1259 (minute 4, `pr-review-fix-scheduler.yml`)
-both target this repository. Do not add a LineageWeave-local duplicate
-workflow. ContextualWisdomLab/.github#1258 merged at exact head `897819c4` to
-repair the pnpm/coverage-evidence workflow; newly created exact PR heads must
-still prove the runtime behavior because merged workflow source alone is not
-check evidence.
-
-Figma design-system boundary (ADR 0002): File ID `1Su3lDRmiZdcUs47t1QwIX`.
-The sanitized file now contains synthetic Event Lineage desktop (`5:14`) and
-mobile (`5:15`) frames with graph direction, event dates, an inference
-boundary, and exact fused-score evidence. Do not copy source-organization
-content into this repository. Storybook remains the executable scene and
-edge-case inventory for repeated web objects; rendered code-to-Figma parity
-still requires same-viewport browser comparison on an exact candidate head.
-
-## 2. User-visible capability baseline
-
-Substantially present on protected `main`:
-
-- PostgreSQL-backed import, normalized provenance, cutoff-aware analysis runs,
-  source revisions, lineage reconstruction, and explicit unavailable states.
-- Authenticated workspace navigation, post detail, localized summaries, 5W1H,
-  R&R/Keyman, evidence citations, chat, organization hierarchy, and lineage DAG
-  (`frontend/src/LineageDag.tsx` is on `main`; the old “DAG view missing”
-  baseline entry is stale).
-- Semantic paragraph/list/table/image-region units that preserve the source
-  representation and provenance instead of flattening it into one body string.
-- FJA→I/O-Psychology semantic layer (ADR 0251): the published DOT/FJA
-  Data/People/Things worker functions (ADR 0232) project into disjoint
-  cognitive, affective, and behavioral constructs with APA 7th anchors,
-  SHACL validation, and a deterministic typed read model
-  (`lineageweave/iopsy_taxonomy.py`); no fitted weight or O*NET/ADR 0248
-  crosswalk is asserted (ADR 0145).
-- Contextual-orchestrator boundaries for adjudication, extraction, summaries,
-  chat, embeddings, and VISION; null channels remain unavailable and are
-  dropped from score fusion.
-- W3C PROV-O projection through normalized provenance tables, with the
-  knowledge graph retained as an explicit navigation projection.
-- Keyverse/Keycloak OIDC, RankWeave fusion port, TEPP measurement client,
-  ThreadWeave tree assembly.
-
-These statements describe source capability, not authenticated production
-corpus acceptance or protected release.
-
-## 3. Historical open-PR inventory (superseded by §1)
-
-Heads below are queue evidence captured at snapshot time; recheck SHA,
-checks, unresolved threads, and independent approval immediately before any
-merge claim. Do not self-approve, force-push, or transfer stale review
-evidence across heads. The org merge scheduler merges only when
-`reviewDecision == APPROVED` on the exact head and Strix evidence is complete.

-| #272 | Verify Global Ask KG/ontology/semantic claims with public SearXNG evidence | #632 preserves internal provenance; public verification acceptance remains open |
-| #277 | TEPP: persist accepted receipts, poll completed results, keep measurement authority distinct | #657 consumer lifecycle; executable producer route remains unavailable |
-| #280 | Full project-lifecycle history and handover intervals | #640 adds case/project journeys and #663 adds evidence-backed Project exploration; authoritative lifecycle reconciliation remains #284 |
-| #284 | Authoritative lifecycle ingestion and idempotent reconciliation | No active delivery PR confirmed |
-| #338 | Evidence-bounded email/project lineage contract for Naruon consumption | #704 recreates the provider-side contract on current `main` without arbitrary fusion weights; #343 remains only a non-default-stack merge and #355 is a distinct calendar contract |
-| #611 | Decompose closed PR #490 ADR 0133–0137 evidence without transferring stale branch state | #631 supplies the current-main inventory only; focused implementation PRs and tests for every unmet criterion are still required |
-
-## 5. Open product and technical gaps
-
-| Gap | Current evidence | Acceptance requirement |
-| --- | --- | --- |
-| Protected release | 12 open PRs at snapshot, all targeting `main` with normal auto-merge enabled. None has the required independent approval, and running checks on #631/#632/#663 are not treated as blockers for safe work on other PRs. #666's merge into the non-default #663 branch is not protected-main delivery | Terminal exact-head checks, no unresolved threads, two independent approvals including last-push approval, protected squash-merge SHA |
-| CI queue release latency | Two Tests runs for already merged PRs occupied the available runner slots while 54 newer runs remained queued. Manual cancellation released the stale work, but the central close workflow was itself queued behind those runs. #634 merged into #631's non-default branch and reuses the repository's existing per-PR concurrency group so a jobless close event can cancel obsolete Tests work before runner allocation; this is not protected-main delivery | Merge #631 through its refreshed protected gate; close a synthetic PR while its Tests run is active and verify the old run becomes cancelled, the close-event jobs remain skipped, and a newer exact-head run starts without manual intervention |
-| Evidence-grounded operations workspace | Protected-main #614 delivers governed semantic Ask, live Similar VOC, disjoint pending/failed analysis metrics, full Storybook state inventory, and current desktop/mobile screenshot evidence. Authorized-corpus backfill acceptance remains unavailable | Perform authenticated authorized-corpus acceptance with aggregate evidence and retain fail-closed no-match behavior |
-| Shared frontend gate | The ADR 0109 login repair is on protected `main`; eight older branches carried the defect and received the same verified repair this loop (#521–#560) | Keep every future branch cut from post-repair bases; re-verify with frontend lint/test/build before push |
-| Identifying baseline regression | `main` gap file listed real post identifiers; separately, closed #506 and pre-existing public history contain a private runtime source-table identifier, while current `main` and #507 trees are clean | Land this non-identifying rewrite, then coordinate ADR 0001 history remediation with security/privacy owners; do not reproduce the value, force-push, or delete evidence ad hoc |
-| Authorized-corpus runtime | Repository tests use synthetic fixtures; private records remain outside git | Authenticated runtime validation returning only aggregate, non-identifying evidence |
-| Concurrent web responsiveness | ADR 0204 releases pooled transactions during provider work, and the synthetic Compose boundary has an authenticated k6 E2E harness for Ask enqueue, concurrent reads, and job polling. PR #633's measured landing-query and event-loop work merged into open parent #629 rather than protected `main`; its aggregate observation improved 25-VU throughput but did not establish a latency SLO. The current exact #629 also persists each completed relation verification before propagating a later provider failure | Land #629 through its refreshed protected gate, rebuild that exact-head application image, and repeat `make load-http` with declared environment concurrency/window and retained raw distributions/resource configuration; set no SLO until representative capacity evidence is approved |
-| Image understanding | Region, OCR, and description work exists across active heads (#405, #419), but current runtime acceptance has not yet proved table-image structure, complete region coverage, or summary/image readiness together | Orchestrator-backed rendered workflow, original/derived asset provenance, region-before-OCR processing, and honest unsupported states; reconcile ADR 0052's image-bearing summary readiness with ADR 0098 before changing sequencing |
-| Semantic source rendering | Paragraph, table, list, formula, and indentation work exists across stacks (#394, #427, #448–#450); #515 adds synthetic backend/frontend parity for deterministic rows/cells, footnote boundaries, and encoded scripts | Land the #427 → #515 stack, then gather authenticated browser evidence that list nesting, continuation alignment, and formula units render without authoring-layout artifacts |
-| Event and project semantics | #663 is the largest current user-visible gap slice: evidence-backed Project nodes, bounded traversal, cutoff/snapshot fencing, exact-value table parity, and localized graph labels. Focus visibility, label-bound, and temporal test-double regressions are repaired. #666's heuristic removal is composed into this parent but is not separately protected-main evidence. #640 separately adds project journeys without claiming authoritative lifecycle status | Combined #663 must pass exact-head checks and independent approval before protected merge. Aggregate authenticated evidence must still prove distinct projects/events and handover intervals without promoting co-occurrence |
-| Voice primary history | Protected `main` `bbb19192` includes ADR 0252 / #761 (migration 0243, GiST primary-period exclusion, `clock_timestamp()` after the source-row lock, API/ontology half-open cutoff SQL). v2.22.1 adds synthetic PostgreSQL integration tests for A → B → A at before/between/after cutoffs, concurrent primary updates, additional-assignment close, and 0237→0243 trigger replay. This is not yet protected-main evidence | Land the live-test slice through the protected gate with independent exact-head APPROVE; close #748 only after that protected delivery |
-| Knowledge Graph readability | #659 recreates the token-backed node-type repair on current `main`, including regression coverage; it is open and therefore not protected-main evidence | Merge #659 normally, then verify light/dark contrast, keyboard graph navigation, full labels, and evidence tables in the authenticated rendered surface |
-| Source-code lookup UX | Source state/detail codes remain evidence-bearing machine values and current detail presentation is dense | Catalog-backed display labels with raw-code provenance, compact 5W1H/source-detail hierarchy, keyboard access, and no unsupported customer/project binding |
-| Calendar / Naruon | #355 delivered the projection contract; v2.17.0 wires operator consumption without forwarding the end-user token. Naruon producer, provider/consumer fixtures, and protected merge remain open (#336) | Verify observed events against the published schema without invented events; keep commitments available when the channel is unwired |
-| SKOS organization aliases | Catalog binding and chip caption live on #480 / #482 | One catalog row per corroborated org; companion caption is hint-only until bound |
-| Event Lineage evidence | Channel evidence and Allen relations live on #387 / #484 | Persist channel scores, explain them in the popup, never invent a fused score |
-| Scientific measurement | Durable accepted TEPP receipts and LineageWeave #614's exact accepted snapshot/cutoff/run/pair-count consumer are protected; TEPP #237 remains open, so no registered producer artifact exists yet. #387 removes inferred/default persistence weights, but several older reconstruction tests still pass hand-authored numeric dictionaries that are not estimator evidence | Land TEPP #237 through its protected gate, then replace remaining reconstruction-test constants with provenance-bearing fast-mlsirm estimates over synthetic fixtures. Retain true-parameter RMSE recovery as the acceptance bar |
-| Asynchronous authorization | Protected `main` rebuilds Global Ask worker scope after the bearer token leaves the request; #468 now persists exact Keyverse organization/process-unit scope in 3NF child tables and intersects it with current affiliations | Land #468 through the protected gate; prove a second affiliation and a revoked process unit cannot widen delayed-job evidence |
-| Planned-facility intent | Planned-facility relationship intent remains only on closed, unmerged #490; earlier stack-only merges were not protected delivery | Recreate the evidence-backed slice on a current base and land through protected `main` before a release claim |
-| Accessibility and responsive UX | #602 delivered base post-detail modal semantics; #605 adds selected-post refocus, collapsed/hidden/inert/CSS-invisible focus exclusion across both modal types, readable evidence separators, focused tests, and desktop/mobile Storybook screenshots | Land #605 through the protected gate, then complete screen-reader and authenticated Playwright acceptance on the exact release head |
-| Design tokens and repeated objects | Token extraction started; sanitized Figma Event Lineage desktop/mobile frames exist, while other repeated product surfaces remain incomplete | Tokens in CSS + Storybook stories for board, popup, DAG, Ask, calendar, forms, charts; same-viewport Figma/runtime visual comparison before release |
-| Frontend delivery performance | #644 implements a native dynamic-import boundary for conditional workspace surfaces and retains accessible loading/error states; exact-head checks passed but the PR is not protected-main evidence | Merge #644 normally, rebuild the protected-main production bundle, and retain the measured chunk inventory rather than raising the warning limit |
-| External integrations | Search, Zotero, calendar, Keyverse, orchestrator, RankWeave, ThreadWeave, TEPP, DiskSage, wardnet | Provider conformance, failure/reconciliation behavior, and provenance-bearing integration evidence |
-| Naruon email/project lineage | #704 provides a strict store-agnostic v1 contract, opaque evidence references, observed/inferred truth separation, knowledge-cutoff admission, and explicit unavailable states. Inferred edges require an injected provenance-bearing fast-mlsirm estimate; no local default weight exists | Merge #704 through protected `main`, publish an immutable attested artifact, then enable the Naruon consumer only against that released version and its contract fixtures |
-| MSA / modular reuse | LineageWeave must run standalone and as a consumer of org packages | Do not reimplement RankWeave/TEPP/orchestrator/ThreadWeave/Keyverse; fix upstream and PR there |
-| Accelerator runtime ownership | ADR 0076/0208 already prohibit local model and mathematical ownership; ADR 0237 now defines MLX as a native orchestrator-side service and TEPP/fast-mlsirm CUDA/OpenCL/CPU profiles as scientific-compute-owner deployments, so LineageWeave Compose remains device-neutral. RankWeave remains the dependency-free Python retrieval-fusion/evaluation owner behind its published contract | TEPP and fast-mlsirm must publish deterministic CPU recovery plus conformance evidence for every advertised CUDA/OpenCL profile; contextual-orchestrator must prove native MLX availability through its provider-neutral health/contract boundary. LineageWeave accepts only versioned, provenance-bearing envelopes and fails closed when the owner is unavailable |
-| Product contract authority | The current LineageWeave PRD records exact-case ecosystem authorities. TEPP, fast-mlsirm, keyverse, ThreadWeave, and RankWeave PR #41 have standalone PRDs; RankWeave's remains unmerged. contextual-orchestrator, disksage, and wardnet still rely on product/architecture documents, and naruon has only a scoped Topic Intelligence PRD | Keep ADRs normative, preserve canonical repository case in machine references, land the pending PRDs, and add standalone PRDs in each remaining owning repository before cross-product release claims exceed its documented boundary |
-| Release quality | PR #660 is now on protected `main`; its pre-merge full Python suite passed 1,352 tests with 17 skips, but release-wide frontend, Storybook, security, browser, and runtime acceptance remain unproven on one exact protected head | Repository-wide coverage, docstrings, Storybook, security, browser, and release evidence on one exact head |
-| PII | Masking would paralyze the product; ADR 0001 forbids identifying artifacts in git | ABAC + authorized runtime; synthetic fixtures in git; no mask-in-place that drops names the operator must read |
-| Database | PostgreSQL, 3NF, snake_case ≥ two words, hot-partition and lock policy | No file DBs; read/write split if lock management fails; whitelist every migration |
-
-### 5.1 Closed PR #490 decomposition (issue #611)
-
-Protected `main` at `04e6b610` and the three open PRs present during the initial
-decomposition were rechecked; the later audit snapshot above includes #631
-itself as the fourth open PR. Protected `main` contains none of PR #490. That PR remains
-closed, unmerged branch evidence; its ADR 0133–0137 files are not normative and
-its 321-file tree must not be replayed. Current-main code and schema searches
-give this delivery matrix:
-
-| Closed-branch decision | Current-main classification | Smallest remaining delivery |
-| --- | --- | --- |
-| ADR 0133 source-reference research | Partial foundation: protected `main` has the self-hosted SearXNG relation-verification client and fail-closed configuration, but it verifies an already extracted relation. It has no source-unit/image-region lead, cited-resource retrieval, claim judgment, or normalized research citation workflow | One post-scoped lead-to-citation slice that reuses the self-hosted SearXNG search boundary, adds public-target SSRF/redirect rejection for result retrieval, and judges through contextual-orchestrator with explicit unavailable outcomes |
-| ADR 0134 token-backed exception messages | Partial: sanitized next-action failures exist, but no shared token-backed exception component or complete Storybook error inventory exists | Migrate one existing unavailable flow to one shared accessible alert and verify its success, unavailable, and retry states |
-| ADR 0135 kind/status-exact analysis actions | Partial: protected `main` has kind-aware start/retry controls plus normative analysis-run, TEPP, cutoff-body, and channel-evidence contracts; it does not contain the closed branch's unified guidance component or its full kind × status interaction inventory | Test the current run-kind/status matrix first, then add only a proven missing state/control pair rather than copying the closed-branch function |
-| ADR 0136 per-post Ask history | Partial: `post_chat_result` / `post_chat_citation`, the authorized post Chat API, and its linear exchange history are on protected `main`. Account-and-post-scoped sessions, ordered turns, list/select/new controls, and batched citation reauthorization are not | Define the 3NF account/post session boundary, bounded batch reauthorization, and one authorized list/load/write path before adding the conversation picker |
-| ADR 0137 cross-post customer identity | Partial foundation: protected `main` preserves source customer hints and has corporate-catalog unique/miss/tie safeguards, but it has no normalized cross-post customer-identity judgment, supporting-post binding, or corporate-name-history workflow | Add only after external corroboration, orchestrator judgment, TEPP ordering, and unique-catalog fail-close can be verified together; never promote a one-post hint |
-
-This matrix satisfies only #611's current-main inventory step. Issue #611
-remains open: every unmet criterion above still needs a focused regression test
-and exact-head current-main implementation PR before its acceptance criteria
-are satisfied. No stale check, review, or implementation is transferred from
-#490.

-## 7. Ecosystem leverage order
-
-Reuse before rebuild. Consume these ContextualWisdomLab packages in this order
-of leverage; open connector PRs there when the defect is upstream:
-
-1. **contextual-orchestrator** — every LLM/VISION/embedding call (Fugu / Conductor / TRINITY routing). Never a raw provider SDK.
-2. **Keyverse** — OIDC issuer, JWKS, tenant principals.
-3. **RankWeave** — fused scores and rankings; never invent a fused score or theta.
-4. **TEPP** — calibrated measurement; persist receipts; no local reimplementation.
-5. **fast-mlsirm** — GRM/GPCM/CAT/FIPC recovery tests (#451–#454) must stay true-parameter RMSE.
-6. **ThreadWeave** — tree assembly.
-7. **Naruon** — calendar and email/project lineage projection (#336, #338, #355).
-8. **DiskSage / wardnet** — storage and network policy as needed.
-9. **ContextualWisdomLab/.github** — required review workflows (OpenCode, Strix, Noema) and the LineageWeave hourly caller (#1259). If stacked PRs miss central review or coverage-evidence fails on pnpm 9 (`--trust-lockfile` is pnpm 11.3) or a missing Vitest coverage provider, fix the org workflow (#1258), not a local bypass.
-
-## 8. Public ontology publication boundary
-
-- PR #426 publishes fragment-addressable HTML, byte-identical Turtle,
-  isomorphic JSON-LD and N-Triples, the PROV-O support profile, and a
-  source-digest manifest from the authoritative ontology.
-- Pull requests validate only. Only protected `main` may publish, and the
-  generated-directory marker, linked-IRI, duplicate-fragment, symlink, and
-  source-overlap checks fail closed.
-- The lowercase knowledge-graph namespace and repository-case support-profile
-  namespace remain distinct until issue #372 delivers a versioned migration
-  and compatibility decision; this publication PR rewrites neither identity.
-- Until the protected deployment and exact URL checks succeed, the public
-  ontology endpoint remains unavailable and must not be represented as live.
-
-## 9. Evidence boundaries
-
-- Never add a real record, title, name, identifier, screenshot, log, benchmark
-  artifact, or documentation example to this repository.
-- Attendance or co-occurrence is not responsibility, project, customer, or
-  affiliation evidence. Preserve uncertainty and provenance.
-- Missing transport, model capability, accepted envelope, or persistence is
-  unavailable or failed evidence, never a placeholder result.
-- Local green tests, bot statuses, auto-merge, and warning-only checks do not
-  prove a protected merge.
-- Re-fetch base/head SHAs, checks, review threads, approvals, rulesets, and the
-  merge SHA immediately before any lifecycle claim.
-- Do not self-approve. Independent OpenCode / Strix / Noema review is required.
-- Do not force-push. Do not treat GitHub Checks duration as a blocker; repair
-  the failing check instead.
-- `COPILOT_GITHUB_TOKEN` is not used.
-
-## 10. Next acceptance loop (autonomous merge order)
-
-Process every open PR in ascending number order, considering leverage; for
-each: check reviews → repair → re-verify Checks → merge → continue. Checks and
-review latency are never blockers — keep working while they settle.
-
-1. Revalidate Strix after merged ContextualWisdomLab/.github#1320, reconcile
-   open .github#1263, and land the atomic hourly LineageWeave caller in open
-   .github#1288 only through their protected gates.
-2. Process main-targeted PRs #629, #631, #632, #639, #640, #643, #644, #657,
-   #658, #659, #660, and #663 only after each exact head shows terminal green
-   required checks plus current-head independent approval. Treat #666's
-   non-default-branch merge only as part of #663's combined candidate and
-   collect all protected evidence on #663's exact head.
-3. While hosted checks or independent reviews wait, resume user-visible gaps
-   from §5 in leverage order:
-   external semantic verification (#272), Naruon calendar (#355/#336), and
-   authenticated operations/ontology publication acceptance. Event Lineage
-   evidence shipped in merged PR #387 and closed issue #274 is not an open gap.
-4. Rename remaining `[Buyer Gap]` issue titles to neutral product-object
-   naming per repository convention (no "Buyer" for internal objects).
-5. Keep psychometric tests as true-parameter recovery (RMSE); never fixture
-   tautologies, invented theta, or hand-authored numeric weights. Remove
-   weights from tests that do not exercise fusion; fusion tests must consume
-   provenance-bearing fast-mlsirm estimates over synthetic fixtures.
-6. Run frontend lint/test/build/Storybook, backend tests, and authenticated
-   browser/accessibility checks on the exact candidate release head.
-7. Fix only evidence-backed failures and repeat the protected merge gate.
-8. Refresh this file each loop with the exact queue state.

+
+## Voice-of-X product and technical gap
+
+ADR 0246 and PR #713 add Supplier, Employee, Business, Regulator, Investor,
+Society, and Process to the original Customer, Customer's Customer,
+Competitor, Market, and Partner source-post vocabulary. The migration,
+published SKOS concepts, product requirements, changelog, and ontology
+round-trip tests agree on the twelve codes. The design is organization-type
+neutral: public bodies, nonprofits, communities, and automated processes do
+not need to be forced into a B2B2C customer chain.
+
+The phrase "all Voice-of-X combinations" does not have a standards-backed
+finite enumeration. ISO's own stakeholder-category guidance says that the
+relevant category set varies by committee and subject; ISO 26000 requires
+stakeholder identification and engagement across organizational contexts;
+AA1000SES requires an inclusive, continuing identification process; and
+Mitchell, Agle, and Wood (1997) model stakeholder salience from combinations
+of power, legitimacy, and urgency rather than a fixed industry-role list.
+Accordingly, ADR 0246 keeps the controlled vocabulary extensible and refuses
+keyword inference, defaults, invented weights, or an asserted exhaustive
+cross-product.
+
+ADR 0256 and migration 0237 now define the persistence contract for
+evidence-bearing composition. A post keeps one source-provided
+`voc_type_code`, mirrored as its sole primary association, while every
+additional voice requires a normalized PROV-O assertion and explicit truth
+status. Half-open assignment intervals preserve a backfilled primary at
+historical cutoffs, close a replaced primary without deleting it, and permit a
+later return to the same Voice. The #717 candidate therefore addresses #748's
+A → B → A storage root cause without adding Cartesian-product codes. Protected
+delivery and synthetic PostgreSQL concurrency/cutoff evidence remain required.
+The remaining acceptance boundary is:
+
+1. preserve the imported primary voice without reclassification (implemented
+   in the candidate migration; migration 0237 replayed twice successfully on
+   an isolated PostgreSQL stack on 2026-08-27, including both primary-sync
+   triggers; a synthetic real-OIDC PostgreSQL API write also proved that the
+   imported primary remains unchanged);
+2. record each additional voice with its own source/evidence and truth state
+   (schema-enforced and candidate `post_admin` API plus live Post-popup

+   topic, channel, lifecycle, and stakeholder-salience attributes;
+4. return only authorized associations through API, JSON-LD, CSV, filters,
+   and UI (candidate API list/detail, filters, combined post-card labels,
+   qualified JSON-LD, exact-value CSV, SHACL, and source-post evidence
+   navigation implemented; the board re-filter matches every associated voice
+   and all twelve governed atomic labels are localized across English, Korean,
+   Chinese, Japanese, and Vietnamese; one bounded query projects assignments
+   for every authorized Post even when another node type is the focus; post
+   detail lists primary and evidence-connected perspectives separately and
+   honors its knowledge cutoff; client-side JSON-LD filtering retains only
+   exact canonical repository-case node and Voice-assignment IRIs rather than
+   accepting cross-origin suffix matches; the exact-value row exposes distinct
+   carrying-Post and authorized derivation-evidence actions, while hidden
+   evidence emits neither an identifier nor a fabricated evidence count;
+   paged JSON-LD merges properties for one subject and unions its multi-Voice
+   relation rather than overwriting an earlier page); and
+5. proves zero-, one-, and multi-voice states with synthetic fixtures,
+   migration replay, ontology/SHACL, API, accessibility, and Storybook edge
+   tests before any release claim. The candidate `CombinedVoiceEvidence` scene
+   covers primary-plus-additional assignments; desktop and mobile screenshots
+   were inspected on 2026-08-27. At 390 CSS pixels the document did not
+   overflow, the named exact-value region remained horizontally scrollable,
+   and the source-post evidence action remained visible and labeled. The
+   `Post/Recorded perspectives` desktop and 390-pixel scenes were also inspected
+   on 2026-08-27; both kept each complete Voice label paired with its imported
+   or evidence-connected state without clipping or horizontal overflow. The
+   `Post/Connect perspective` ready/success scenes were inspected at 1440 and
+   390 CSS pixels on 2026-08-27: labels stay above controls, the mobile form is
+   a single column, controls meet the 44-pixel touch target, and no horizontal
+   overflow was visible.
+
+At this snapshot the repository had 42 open PRs and 11 open issues. PR #713
+head `850494c3` includes the review-driven localization of all twelve governed
+Voice labels. Its frontend, ontology publication, static-analysis, dependency,
+coverage, full-suite, CodeRabbit, Devin, and OpenCode checks passed. Strix
+failed closed before producing a vulnerability report:
+the primary NVIDIA NIM model returned HTTP 429, one configured fallback had
+reached end of life, and the OpenAI fallback reported exhausted credits. A
+same-head retry completed on 2026-08-27 with the explicit
+`STRIX_PROVIDER_UNAVAILABLE` annotation and again produced no vulnerability
+report. This
+is provider/control-plane unavailability, not a vulnerability result or
+permission to transfer an older success. Auto-merge remains enabled, while an
+independent approval is still required. PR #717 implementation head
+`d5fe4828` merges that
+parent change without force-pushing and separates the complete governed Voice
+catalog used for authoring from usage-derived Board filters, so an authorized
+administrator can attach a Voice that no visible Post carries yet. It also
+labels Voice exact-value navigation as opening the carrying Post rather than
+misrepresenting that Post as the separately recorded derivation evidence. Its
+CodeRabbit and hosted Frontend/Storybook checks passed at predecessor head
+`ebb4ef1d`; refreshed checks for exact head `d5fe4828` were queued. Focused local
+backend tests, frontend type checking/lint, and the new unused-Voice authoring
+regression passed, and the exact-value navigation tests, lint, and type check
+passed after the label repair. The paged JSON-LD union regression and Voice
+evidence navigation suite passed 23 focused frontend tests; 48 focused backend
+ontology/docstring tests also passed. The full backend suite at predecessor
+head `ebb4ef1d` passed 1,366 tests with 148 environment-dependent skips. The
+real-integration fixture now applies
+the existing migration 0042 before the expanded taxonomy migrations instead
+of seeding an incomplete or duplicate legacy catalog; the exact
+`d5fe4828` authenticated post-list integration passed in 91.54 seconds. The
+wider local frontend run had 400 passes and eight five-second timeouts under
+concurrent backend-suite load; a later App-only run had 94 passes and five
+five-second timeouts, while the hosted Frontend/Storybook job passed on
+`ebb4ef1d`. Neither local timeout run is promoted to full-suite success. An initial
+authenticated integration attempt was unavailable while Keycloak initialized;
+a later retry against the shared synthetic stack succeeded in 56.18 seconds
+and proved the permission, API, PostgreSQL,
+PROV-O, and primary-preservation assertions; no identifying source data was
+used or retained. No self-approval, admin bypass, or stale-head check transfer
+is permitted.
+
+Stacked PR #717 carries ADR 0256, migration 0237, qualified
+ontology terms, persistence/API/UI tests, and the category-validation review
+repairs plus a local candidate admin write path that creates its PROV-O
+derivation from an authorized evidence Post. Its JSON-LD projection names that
+evidence Post only when it is in the authorized visible set and omits the whole
+additional assignment otherwise, preserving the SHACL evidence minimum without
+substituting the assigned Post. It targets
+#713's branch, not protected `main`;
+its checks and review are candidate evidence only. After
+#713 reaches protected main, #717 must be synchronized, retargeted to `main`,
+and revalidated on its then-current head.
+
+Downstream Dashboard repair PR #737 exact head `a837ee5d` is stacked on base
+`7c7bb2cf`, which contains migration 0235 through a non-#713 composition but
+does not contain #713's twelve-label locale update. Its added Voice labels are
+therefore necessary on that exact base, yet overlap #713 and must be reconciled
+when the stack is eventually rebuilt on protected `main`; neither branch is a
+second taxonomy authority, and pre-parent Checks cannot transfer across that
+restack.
+The remaining user-visible gap is evidence-bearing composition. A post still
+has one source-provided `voc_type_code`; the product cannot yet represent a
+single record that intentionally carries multiple independently evidenced
+voices, nor expose the combination in filters, exports, or the ontology
+neighborhood. Do not solve this by adding every Cartesian-product code. The
+acceptance boundary for a later ADR is a normalized, provenance-bearing
+multi-voice association that:
+
+1. preserves the imported primary voice without reclassification;
+2. records each additional voice with its own source/evidence and truth state;
+3. keeps post voice distinct from named-counterparty relationship, actor role,
+   topic, channel, lifecycle, and stakeholder-salience attributes;
+4. returns only authorized associations through API, JSON-LD, CSV, filters,
+   and UI; and
+5. proves zero-, one-, and multi-voice states with synthetic fixtures,
+   migration replay, ontology/SHACL, API, accessibility, and Storybook edge
+   tests before any release claim.
+
+At this snapshot the repository had 23 open PRs and 10 open issues. PR #713
+was `MERGEABLE` but policy-blocked: exact-head backend, frontend, CodeQL,
+ontology-publication, Semgrep, OSV, Trivy, Scorecard, Noema, Devin, and
+CodeRabbit checks were successful; `coverage-source-tree` was queued; Strix
+failed closed with `STRIX_PROVIDER_UNAVAILABLE`; and an independent approval
+was still required. Auto-merge remains enabled. No self-approval, admin bypass,
+or stale-head check transfer is permitted.
+
+References for this gap use the APA 7 entries in ADR 0246. Current supporting
+standards pages were rechecked on 2026-08-27: ISO 26000:2010 remains applicable
+to all organization types and AA1000SES v3 is under development for a planned
+2027 release, so the repository continues to cite the published AA1000SES
+(2015) contract rather than treating the draft as adopted policy.

+## Current occupational semantic-layer gap
+
+ADR 0245's candidate branch publishes only a provenance-safe classification
+foundation: 23 2018 SOC major groups, four O*NET 31.0 Job Zone categories, six RIASEC interest
+types and their published adjacency, six explicitly legacy work-value clusters, seven
+revised work-style dimensions, and four ability domains. It asserts no
+occupation-to-characteristic instance profile and therefore does **not** yet
+satisfy the requested job-family, job-series, and occupation-level coverage of
+work cognition, affect, behavior, or their empirical relations. This is an
+explicit unavailable state, not a reason to infer mappings from labels.
+
+| Gap | Current evidence | Acceptance requirement |
+|---|---|---|
+| Classification depth | ADR 0245 and `lineageweave/io_taxonomy.py` expose SOC major groups only; schemes now name versioned PROV source entities and the stable O*NET 31.0 Job Zone JSON digest | Import a versioned authoritative classification release with provenance-preserving major, minor, broad, and detailed occupation identifiers; add ISCO/ESCO crosswalks only where the publishing authority supplies them |
+| Construct granularity | The candidate ontology exposes 23 high-level characteristic concepts | Publish source-versioned O*NET abilities, skills, knowledge, work activities, work context, interests, and work styles without collapsing cognition, affect, and behavior into one dimension; preserve removed Work Values only as versioned legacy content |
+| Occupation-to-construct relations | ADR 0245 deliberately declares relation properties without instance assertions | Persist released source observations with source version, occupation code, element identifier, scale identifier, value, sample/error metadata when supplied, and provenance; never invent or locally normalize a weight |
+| Job-family and job-series semantics | No authoritative employer-specific job architecture is present | Define an organization-neutral import contract that preserves the authorized source hierarchy and distinguishes standard occupation codes from employer job families/series; no label-based binding |
+| Temporal and multilevel interpretation | Static vocabulary only; no person-level inference is asserted | Version valid and transaction time, preserve occupation/organization/unit nesting and multiple membership, and require TEPP or the owning Rust psychometric service before any calibrated temporal or multilevel result |
+| Product consumption | The read model has no persisted semantic-layer consumer or authenticated UI evidence | Add a provenance-bearing API and accessible ontology exploration flow, then verify synthetic Storybook edge states plus authenticated aggregate runtime evidence without exposing identifying records |

+The `f0b96029` Storybook build was rendered at 1440×1100 and 402×1200 with
+synthetic evidence; `416fd19d` changes only post-navigation request isolation.
+Desktop inspection showed all four case kinds, five non-conflated metrics,
+project-journey ordering, cited facts, and evidence actions without horizontal
+card overflow. Narrow inspection showed two-column metrics, readable cards and
+44px-class actions; the project journey remains intentionally horizontally
+scrollable. No identifying runtime record or screenshot is committed. The
+`EvidenceReady`, `NarrowViewport`, `AnalysisPendingAndMissingEvidence`,
+`AnalysisFailed`, and `LoadError` scenes cover the ADR 0206 state inventory.
+Authenticated authorized-corpus acceptance remains separate and may return
+only aggregate, non-identifying evidence to this repository.

+
+PR #607 first merged as `61fd631c7bb3c57113fd19763c2c43161eeb2824`
+into #606's non-default branch. PR #606 subsequently passed the protected gate,
+so the combined TEPP-consumer and operations-dashboard implementation is now
+on `main`; the still-open TEPP producer PR #237 keeps end-to-end anchor
+acceptance unavailable.
+
+PR #604 was closed unmerged after its exact OIDC repair was composed into #605;
+its green or pending checks are not delivery evidence. PR #482 merged as
+protected-main commit `464ff25002044b9d933c8eefd36c8def7ca0ffd8`
+with package conflict markers, identifying baseline records, and an OIDC
+return-context regression. PR #603 repaired the package/privacy and
+analysis-run transaction defects through protected main at `4f53190b`; the
+OIDC defect remains delivered until #604 or the composed #605 passes the
+protected gate. Protected main is therefore not yet a release candidate.
+
+PR #592 first merged as `3b3af3b4fe9c439354433a43444e05f37ab24ea3`
+into #590's non-default stack base at `2f033ba3`. The complete stack then
+passed the protected gate and #590 merged to `main` as
+`1d1379fc59d9dac6e9c8bfa4812313e3b9e8f3c8`.
+
+PR #521 merged through protected `main` as
+`3797f063b1a7396972a749aa81f23745acccbee1`; it is release evidence and no
+longer part of the open queue. That merge also left a standalone conflict
+marker and duplicated stale tail in `CLAUDE.md`; #594 repaired it through
+protected `main` as `241be2dddf657f854cb8be54fe11d4ef48d37976`.
+
+Protected main now contains the ADR 0109 OIDC return restoration from #605,
+including fragment preservation and storage fallback. The #606 dashboard
+landing must additionally route `?post=` deep links to the Board; that focused
+regression is part of the current candidate and is not delivery evidence yet.
+
+Three systemic gates currently dominate the queue:
+
+1. **Strix visibility lookup failure (org control plane).** PR #600 exact head
+   `7580bdc9` failed before scanning because the required-workflow token could
+   not resolve this public repository after six API retries. The root repair is
+   ContextualWisdomLab/.github#1320 at `3b9b2380`: ordinary PR, push, and
+   schedule runs use trusted event visibility; cross-repository dispatch keeps
+   authoritative public/private/internal visibility; private and internal
+   repositories remain on private-capable providers. The exact head also
+   composes the executable fallback contract and classifies bounded NVIDIA
+   `ServiceUnavailableError` overload evidence as retryable across configured
+   distinct models without weakening exhaustion or vulnerability fail-close.
+   A hosted fallback then completed with zero vulnerabilities but was rejected
+   because the generic warning gate treated Strix's fallback-model banner and
+   a Hugging Face unauthenticated-download notice as provider failures. The
+   current head removes only those two exact scanner notices before the
+   existing general warning and explicit 429/provider failure checks. The
+   current head also clears a foreign NVIDIA/OpenRouter endpoint before a
+   direct-OpenAI fallback while retaining an explicitly configured
+   direct-OpenAI primary endpoint. The prior full quick-gate harness, overload
+   path, 12 visibility-contract tests, and the focused cross-provider endpoint
+   contract passed; exact-head hosted revalidation remains pending. It is blocked on
+   hosted exact-head gates and independent review, so no repaired
+   protected-main Strix runtime evidence exists yet.
+2. **Strix provider unavailability (org control plane).** The central required
+   Strix scan on .github#1320 failed when NVIDIA returned `Service temporarily
+   overloaded`; the gate correctly failed closed but did not try its configured
+   distinct fallbacks because the service-unavailable classifier excluded the
+   NVIDIA provider. Exact head `3b9b2380` composes that execution repair and the
+   two exact non-fatal scanner-notice exclusions while keeping
+   incomplete exhaustion non-passing. This is still an unmerged control-plane
+   proposal, not protected-main or downstream runtime evidence.
+3. **Current-head independent approval.** The org merge scheduler requires
+   `reviewDecision == APPROVED` plus complete Strix evidence on the exact
+   head. Bot review evidence regenerates per push, so any repair push resets
+   the review clock by design; this is expected and not a bypass target.

+This documentation is owned by protected `main` again: the #426 stack landed,
+so hidden-stack merges (#494, #497, #499, #505, #509 into unprotected parent
+branches) are historical context only and no longer gate anything.
+
+The current protected-`main` and exact #507 trees are clean of the private
+runtime source-table identifier present in the closed #506 head and older
+public history. Do not reproduce or hint at its value. Historical remediation
+requires the ADR 0001 incident process and security/privacy-owner coordination;
+never force-push or delete evidence ad hoc.
+
+The Grok durable hourly loop and the central thin GitHub Actions caller
+ContextualWisdomLab/.github#1259 (minute 4, `pr-review-fix-scheduler.yml`)
+both target this repository. Do not add a LineageWeave-local duplicate
+workflow. ContextualWisdomLab/.github#1258 merged at exact head `897819c4` to
+repair the pnpm/coverage-evidence workflow; newly created exact PR heads must
+still prove the runtime behavior because merged workflow source alone is not
+check evidence.
+
+Figma design-system boundary (ADR 0002): File ID `1Su3lDRmiZdcUs47t1QwIX`.
+The sanitized file now contains synthetic Event Lineage desktop (`5:14`) and
+mobile (`5:15`) frames with graph direction, event dates, an inference
+boundary, and exact fused-score evidence. Do not copy source-organization
+content into this repository. Storybook remains the executable scene and
+edge-case inventory for repeated web objects; rendered code-to-Figma parity
+still requires same-viewport browser comparison on an exact candidate head.
+
+## 2. User-visible capability baseline
+
+Substantially present on protected `main`:
+
+- PostgreSQL-backed import, normalized provenance, cutoff-aware analysis runs,
+  source revisions, lineage reconstruction, and explicit unavailable states.
+- Authenticated workspace navigation, post detail, localized summaries, 5W1H,
+  R&R/Keyman, evidence citations, chat, organization hierarchy, and lineage DAG
+  (`frontend/src/LineageDag.tsx` is on `main`; the old “DAG view missing”
+  baseline entry is stale).
+- Semantic paragraph/list/table/image-region units that preserve the source
+  representation and provenance instead of flattening it into one body string.
+- FJA→I/O-Psychology semantic layer (ADR 0251): the published DOT/FJA
+  Data/People/Things worker functions (ADR 0232) project into disjoint
+  cognitive, affective, and behavioral constructs with APA 7th anchors,
+  SHACL validation, and a deterministic typed read model
+  (`lineageweave/iopsy_taxonomy.py`); no fitted weight or O*NET/ADR 0248
+  crosswalk is asserted (ADR 0145).
+- Contextual-orchestrator boundaries for adjudication, extraction, summaries,
+  chat, embeddings, and VISION; null channels remain unavailable and are
+  dropped from score fusion.
+- W3C PROV-O projection through normalized provenance tables, with the
+  knowledge graph retained as an explicit navigation projection.
+- Keyverse/Keycloak OIDC, RankWeave fusion port, TEPP measurement client,
+  ThreadWeave tree assembly.
+
+These statements describe source capability, not authenticated production
+corpus acceptance or protected release.
+
+## 3. Historical open-PR inventory (superseded by §1)
+
+Heads below are queue evidence captured at snapshot time; recheck SHA,
+checks, unresolved threads, and independent approval immediately before any
+merge claim. Do not self-approve, force-push, or transfer stale review
+evidence across heads. The org merge scheduler merges only when
+`reviewDecision == APPROVED` on the exact head and Strix evidence is complete.

+| #338 | Evidence-bounded email/project lineage contract for Naruon consumption | #704 recreates the provider-side contract on current `main` without arbitrary fusion weights; #343 remains only a non-default-stack merge and #355 is a distinct calendar contract |
+| #611 | Decompose closed PR #490 ADR 0133–0137 evidence without transferring stale branch state | #631 supplies the current-main inventory only; focused implementation PRs and tests for every unmet criterion are still required |
+
+## 5. Open product and technical gaps
+
+| Gap | Current evidence | Acceptance requirement |
+| --- | --- | --- |
+| Protected release | 12 open PRs at snapshot, all targeting `main` with normal auto-merge enabled. None has the required independent approval, and running checks on #631/#632/#663 are not treated as blockers for safe work on other PRs. #666's merge into the non-default #663 branch is not protected-main delivery | Terminal exact-head checks, no unresolved threads, two independent approvals including last-push approval, protected squash-merge SHA |
+| CI queue release latency | Two Tests runs for already merged PRs occupied the available runner slots while 54 newer runs remained queued. Manual cancellation released the stale work, but the central close workflow was itself queued behind those runs. #634 merged into #631's non-default branch and reuses the repository's existing per-PR concurrency group so a jobless close event can cancel obsolete Tests work before runner allocation; this is not protected-main delivery | Merge #631 through its refreshed protected gate; close a synthetic PR while its Tests run is active and verify the old run becomes cancelled, the close-event jobs remain skipped, and a newer exact-head run starts without manual intervention |
+| Evidence-grounded operations workspace | Protected-main #614 delivers governed semantic Ask, live Similar VOC, disjoint pending/failed analysis metrics, full Storybook state inventory, and current desktop/mobile screenshot evidence. Authorized-corpus backfill acceptance remains unavailable | Perform authenticated authorized-corpus acceptance with aggregate evidence and retain fail-closed no-match behavior |
+| Shared frontend gate | The ADR 0109 login repair is on protected `main`; eight older branches carried the defect and received the same verified repair this loop (#521–#560) | Keep every future branch cut from post-repair bases; re-verify with frontend lint/test/build before push |
+| Identifying baseline regression | `main` gap file listed real post identifiers; separately, closed #506 and pre-existing public history contain a private runtime source-table identifier, while current `main` and #507 trees are clean | Land this non-identifying rewrite, then coordinate ADR 0001 history remediation with security/privacy owners; do not reproduce the value, force-push, or delete evidence ad hoc |
+| Authorized-corpus runtime | Repository tests use synthetic fixtures; private records remain outside git | Authenticated runtime validation returning only aggregate, non-identifying evidence |
+| Concurrent web responsiveness | ADR 0204 releases pooled transactions during provider work, and the synthetic Compose boundary has an authenticated k6 E2E harness for Ask enqueue, concurrent reads, and job polling. PR #633's measured landing-query and event-loop work merged into open parent #629 rather than protected `main`; its aggregate observation improved 25-VU throughput but did not establish a latency SLO. The current exact #629 also persists each completed relation verification before propagating a later provider failure | Land #629 through its refreshed protected gate, rebuild that exact-head application image, and repeat `make load-http` with declared environment concurrency/window and retained raw distributions/resource configuration; set no SLO until representative capacity evidence is approved |
+| Image understanding | Region, OCR, and description work exists across active heads (#405, #419), but current runtime acceptance has not yet proved table-image structure, complete region coverage, or summary/image readiness together | Orchestrator-backed rendered workflow, original/derived asset provenance, region-before-OCR processing, and honest unsupported states; reconcile ADR 0052's image-bearing summary readiness with ADR 0098 before changing sequencing |
+| Semantic source rendering | Paragraph, table, list, formula, and indentation work exists across stacks (#394, #427, #448–#450); #515 adds synthetic backend/frontend parity for deterministic rows/cells, footnote boundaries, and encoded scripts | Land the #427 → #515 stack, then gather authenticated browser evidence that list nesting, continuation alignment, and formula units render without authoring-layout artifacts |
+| Event and project semantics | #663 is the largest current user-visible gap slice: evidence-backed Project nodes, bounded traversal, cutoff/snapshot fencing, exact-value table parity, and localized graph labels. Focus visibility, label-bound, and temporal test-double regressions are repaired. #666's heuristic removal is composed into this parent but is not separately protected-main evidence. #640 separately adds project journeys without claiming authoritative lifecycle status | Combined #663 must pass exact-head checks and independent approval before protected merge. Aggregate authenticated evidence must still prove distinct projects/events and handover intervals without promoting co-occurrence |
+| Voice primary history | Protected `main` `bbb19192` includes ADR 0252 / #761 (migration 0243, GiST primary-period exclusion, `clock_timestamp()` after the source-row lock, API/ontology half-open cutoff SQL). v2.22.1 adds synthetic PostgreSQL integration tests for A → B → A at before/between/after cutoffs, concurrent primary updates, additional-assignment close, and 0237→0243 trigger replay. This is not yet protected-main evidence | Land the live-test slice through the protected gate with independent exact-head APPROVE; close #748 only after that protected delivery |
+| Knowledge Graph readability | #659 recreates the token-backed node-type repair on current `main`, including regression coverage; it is open and therefore not protected-main evidence | Merge #659 normally, then verify light/dark contrast, keyboard graph navigation, full labels, and evidence tables in the authenticated rendered surface |
+| Source-code lookup UX | Source state/detail codes remain evidence-bearing machine values and current detail presentation is dense | Catalog-backed display labels with raw-code provenance, compact 5W1H/source-detail hierarchy, keyboard access, and no unsupported customer/project binding |
+| Calendar / Naruon | #355 delivered the projection contract; v2.17.0 wires operator consumption without forwarding the end-user token. Naruon producer, provider/consumer fixtures, and protected merge remain open (#336) | Verify observed events against the published schema without invented events; keep commitments available when the channel is unwired |
+| SKOS organization aliases | Catalog binding and chip caption live on #480 / #482 | One catalog row per corroborated org; companion caption is hint-only until bound |
+| Event Lineage evidence | Channel evidence and Allen relations live on #387 / #484 | Persist channel scores, explain them in the popup, never invent a fused score |
+| Scientific measurement | Durable accepted TEPP receipts and LineageWeave #614's exact accepted snapshot/cutoff/run/pair-count consumer are protected; TEPP #237 remains open, so no registered producer artifact exists yet. #387 removes inferred/default persistence weights, but several older reconstruction tests still pass hand-authored numeric dictionaries that are not estimator evidence | Land TEPP #237 through its protected gate, then replace remaining reconstruction-test constants with provenance-bearing fast-mlsirm estimates over synthetic fixtures. Retain true-parameter RMSE recovery as the acceptance bar |
+| Asynchronous authorization | Protected `main` rebuilds Global Ask worker scope after the bearer token leaves the request; #468 now persists exact Keyverse organization/process-unit scope in 3NF child tables and intersects it with current affiliations | Land #468 through the protected gate; prove a second affiliation and a revoked process unit cannot widen delayed-job evidence |
+| Planned-facility intent | Planned-facility relationship intent remains only on closed, unmerged #490; earlier stack-only merges were not protected delivery | Recreate the evidence-backed slice on a current base and land through protected `main` before a release claim |
+| Accessibility and responsive UX | #602 delivered base post-detail modal semantics; #605 adds selected-post refocus, collapsed/hidden/inert/CSS-invisible focus exclusion across both modal types, readable evidence separators, focused tests, and desktop/mobile Storybook screenshots | Land #605 through the protected gate, then complete screen-reader and authenticated Playwright acceptance on the exact release head |
+| Design tokens and repeated objects | Token extraction started; sanitized Figma Event Lineage desktop/mobile frames exist, while other repeated product surfaces remain incomplete | Tokens in CSS + Storybook stories for board, popup, DAG, Ask, calendar, forms, charts; same-viewport Figma/runtime visual comparison before release |
+| Frontend delivery performance | #644 implements a native dynamic-import boundary for conditional workspace surfaces and retains accessible loading/error states; exact-head checks passed but the PR is not protected-main evidence | Merge #644 normally, rebuild the protected-main production bundle, and retain the measured chunk inventory rather than raising the warning limit |
+| External integrations | Search, Zotero, calendar, Keyverse, orchestrator, RankWeave, ThreadWeave, TEPP, DiskSage, wardnet | Provider conformance, failure/reconciliation behavior, and provenance-bearing integration evidence |
+| Naruon email/project lineage | #704 provides a strict store-agnostic v1 contract, opaque evidence references, observed/inferred truth separation, knowledge-cutoff admission, and explicit unavailable states. Inferred edges require an injected provenance-bearing fast-mlsirm estimate; no local default weight exists | Merge #704 through protected `main`, publish an immutable attested artifact, then enable the Naruon consumer only against that released version and its contract fixtures |
+| MSA / modular reuse | LineageWeave must run standalone and as a consumer of org packages | Do not reimplement RankWeave/TEPP/orchestrator/ThreadWeave/Keyverse; fix upstream and PR there |
+| Accelerator runtime ownership | ADR 0076/0208 already prohibit local model and mathematical ownership; ADR 0237 now defines MLX as a native orchestrator-side service and TEPP/fast-mlsirm CUDA/OpenCL/CPU profiles as scientific-compute-owner deployments, so LineageWeave Compose remains device-neutral. RankWeave remains the dependency-free Python retrieval-fusion/evaluation owner behind its published contract | TEPP and fast-mlsirm must publish deterministic CPU recovery plus conformance evidence for every advertised CUDA/OpenCL profile; contextual-orchestrator must prove native MLX availability through its provider-neutral health/contract boundary. LineageWeave accepts only versioned, provenance-bearing envelopes and fails closed when the owner is unavailable |
+| Product contract authority | The current LineageWeave PRD records exact-case ecosystem authorities. TEPP, fast-mlsirm, keyverse, ThreadWeave, and RankWeave PR #41 have standalone PRDs; RankWeave's remains unmerged. contextual-orchestrator, disksage, and wardnet still rely on product/architecture documents, and naruon has only a scoped Topic Intelligence PRD | Keep ADRs normative, preserve canonical repository case in machine references, land the pending PRDs, and add standalone PRDs in each remaining owning repository before cross-product release claims exceed its documented boundary |
+| Release quality | PR #660 is now on protected `main`; its pre-merge full Python suite passed 1,352 tests with 17 skips, but release-wide frontend, Storybook, security, browser, and runtime acceptance remain unproven on one exact protected head | Repository-wide coverage, docstrings, Storybook, security, browser, and release evidence on one exact head |
+| PII | Masking would paralyze the product; ADR 0001 forbids identifying artifacts in git | ABAC + authorized runtime; synthetic fixtures in git; no mask-in-place that drops names the operator must read |
+| Database | PostgreSQL, 3NF, snake_case ≥ two words, hot-partition and lock policy | No file DBs; read/write split if lock management fails; whitelist every migration |
+
+### 5.1 Closed PR #490 decomposition (issue #611)
+
+Protected `main` at `04e6b610` and the three open PRs present during the initial
+decomposition were rechecked; the later audit snapshot above includes #631
+itself as the fourth open PR. Protected `main` contains none of PR #490. That PR remains
+closed, unmerged branch evidence; its ADR 0133–0137 files are not normative and
+its 321-file tree must not be replayed. Current-main code and schema searches
+give this delivery matrix:
+
+| Closed-branch decision | Current-main classification | Smallest remaining delivery |
+| --- | --- | --- |
+| ADR 0133 source-reference research | Partial foundation: protected `main` has the self-hosted SearXNG relation-verification client and fail-closed configuration, but it verifies an already extracted relation. It has no source-unit/image-region lead, cited-resource retrieval, claim judgment, or normalized research citation workflow | One post-scoped lead-to-citation slice that reuses the self-hosted SearXNG search boundary, adds public-target SSRF/redirect rejection for result retrieval, and judges through contextual-orchestrator with explicit unavailable outcomes |
+| ADR 0134 token-backed exception messages | Partial: sanitized next-action failures exist, but no shared token-backed exception component or complete Storybook error inventory exists | Migrate one existing unavailable flow to one shared accessible alert and verify its success, unavailable, and retry states |
+| ADR 0135 kind/status-exact analysis actions | Partial: protected `main` has kind-aware start/retry controls plus normative analysis-run, TEPP, cutoff-body, and channel-evidence contracts; it does not contain the closed branch's unified guidance component or its full kind × status interaction inventory | Test the current run-kind/status matrix first, then add only a proven missing state/control pair rather than copying the closed-branch function |
+| ADR 0136 per-post Ask history | Partial: `post_chat_result` / `post_chat_citation`, the authorized post Chat API, and its linear exchange history are on protected `main`. Account-and-post-scoped sessions, ordered turns, list/select/new controls, and batched citation reauthorization are not | Define the 3NF account/post session boundary, bounded batch reauthorization, and one authorized list/load/write path before adding the conversation picker |
+| ADR 0137 cross-post customer identity | Partial foundation: protected `main` preserves source customer hints and has corporate-catalog unique/miss/tie safeguards, but it has no normalized cross-post customer-identity judgment, supporting-post binding, or corporate-name-history workflow | Add only after external corroboration, orchestrator judgment, TEPP ordering, and unique-catalog fail-close can be verified together; never promote a one-post hint |
+
+This matrix satisfies only #611's current-main inventory step. Issue #611
+remains open: every unmet criterion above still needs a focused regression test
+and exact-head current-main implementation PR before its acceptance criteria
+are satisfied. No stale check, review, or implementation is transferred from
+#490.

+1. **contextual-orchestrator** — every LLM/VISION/embedding call (Fugu / Conductor / TRINITY routing). Never a raw provider SDK.
+2. **Keyverse** — OIDC issuer, JWKS, tenant principals.
+3. **RankWeave** — fused scores and rankings; never invent a fused score or theta.
+4. **TEPP** — calibrated measurement; persist receipts; no local reimplementation.
+5. **fast-mlsirm** — GRM/GPCM/CAT/FIPC recovery tests (#451–#454) must stay true-parameter RMSE.
+6. **ThreadWeave** — tree assembly.
+7. **Naruon** — calendar and email/project lineage projection (#336, #338, #355).
+8. **DiskSage / wardnet** — storage and network policy as needed.
+9. **ContextualWisdomLab/.github** — required review workflows (OpenCode, Strix, Noema) and the LineageWeave hourly caller (#1259). If stacked PRs miss central review or coverage-evidence fails on pnpm 9 (`--trust-lockfile` is pnpm 11.3) or a missing Vitest coverage provider, fix the org workflow (#1258), not a local bypass.
+
+## 8. Public ontology publication boundary
+
+- PR #426 publishes fragment-addressable HTML, byte-identical Turtle,
+  isomorphic JSON-LD and N-Triples, the PROV-O support profile, and a
+  source-digest manifest from the authoritative ontology.
+- Pull requests validate only. Only protected `main` may publish, and the
+  generated-directory marker, linked-IRI, duplicate-fragment, symlink, and
+  source-overlap checks fail closed.
+- The lowercase knowledge-graph namespace and repository-case support-profile
+  namespace remain distinct until issue #372 delivers a versioned migration
+  and compatibility decision; this publication PR rewrites neither identity.
+- Until the protected deployment and exact URL checks succeed, the public
+  ontology endpoint remains unavailable and must not be represented as live.
+
+## 9. Evidence boundaries
+
+- Never add a real record, title, name, identifier, screenshot, log, benchmark
+  artifact, or documentation example to this repository.
+- Attendance or co-occurrence is not responsibility, project, customer, or
+  affiliation evidence. Preserve uncertainty and provenance.
+- Missing transport, model capability, accepted envelope, or persistence is
+  unavailable or failed evidence, never a placeholder result.
+- Local green tests, bot statuses, auto-merge, and warning-only checks do not
+  prove a protected merge.
+- Re-fetch base/head SHAs, checks, review threads, approvals, rulesets, and the
+  merge SHA immediately before any lifecycle claim.
+- Do not self-approve. Independent OpenCode / Strix / Noema review is required.
+- Do not force-push. Do not treat GitHub Checks duration as a blocker; repair
+  the failing check instead.
+- `COPILOT_GITHUB_TOKEN` is not used.
+
+## 10. Next acceptance loop (autonomous merge order)
+
+Process every open PR in ascending number order, considering leverage; for
+each: check reviews → repair → re-verify Checks → merge → continue. Checks and
+review latency are never blockers — keep working while they settle.
+
+1. Revalidate Strix after merged ContextualWisdomLab/.github#1320, reconcile
+   open .github#1263, and land the atomic hourly LineageWeave caller in open
+   .github#1288 only through their protected gates.
+2. Process main-targeted PRs #629, #631, #632, #639, #640, #643, #644, #657,
+   #658, #659, #660, and #663 only after each exact head shows terminal green
+   required checks plus current-head independent approval. Treat #666's
+   non-default-branch merge only as part of #663's combined candidate and
+   collect all protected evidence on #663's exact head.
+3. While hosted checks or independent reviews wait, resume user-visible gaps
+   from §5 in leverage order:
+   external semantic verification (#272), Naruon calendar (#355/#336), and
+   authenticated operations/ontology publication acceptance. Event Lineage
+   evidence shipped in merged PR #387 and closed issue #274 is not an open gap.
+4. Rename remaining `[Buyer Gap]` issue titles to neutral product-object
+   naming per repository convention (no "Buyer" for internal objects).
+5. Keep psychometric tests as true-parameter recovery (RMSE); never fixture
+   tautologies, invented theta, or hand-authored numeric weights. Remove
+   weights from tests that do not exercise fusion; fusion tests must consume
+   provenance-bearing fast-mlsirm estimates over synthetic fixtures.
+6. Run frontend lint/test/build/Storybook, backend tests, and authenticated
+   browser/accessibility checks on the exact candidate release head.
+7. Fix only evidence-backed failures and repeat the protected merge gate.
+8. Refresh this file each loop with the exact queue state.
+
+## 11. Spec pointers (derive, do not fork)

+- Research grounding: ADR 0084, `docs/lineage-bi-research-notes.md`

 - Publication must serialize with child key/text mutation so a complete resource cannot become incomplete after the publication check.

+Rejected. That ordering is correct for authority but wasteful on an ordinary cache miss: the request first pays for a digest query and then must reacquire PostgreSQL for the complete projection. Fetching the bounded candidate first does not transfer authority to Valkey because no cache value is returned before PostgreSQL verification. It lets a true miss use one complete PostgreSQL query while a valid hit uses one digest-only PostgreSQL query.

 Child insert/update/delete obtains a `FOR UPDATE` lock on the parent resource. Publication already locks the resource row through its update.

 - Hosted verification alignment `e33ad222e2b7b162e872ecb6919401d0291ed032`: ordinary contract tests cover NBSP/U+3000 admission and require the explicit migration representation while rejecting the superseded regex contract.

+- Causal repair `15c344eecce7ce20affd397d5ff2969fd8fed4c5`: exact-version reads now fetch the bounded candidate without a database lease, use digest-only PostgreSQL admission for a present candidate, and use one complete PostgreSQL query for a true miss.
+- Verification alignment `49cc023aaf35aea0b55f927bc2b4445ca116089b`: malformed, identity-mismatched, incomplete, and value-mismatched present candidates remain fail-closed and converge through digest admission plus authoritative PostgreSQL fallback instead of inheriting the normal miss budget.
 
 These commits are branch evidence only. This ADR remains Proposed until the exact protected-line implementation and dependent API/frontend cutover are verified.

 5. Keep #929 on normal auto-merge; do not bypass or release until exact-head
    gates and independent review are complete.
 
+## Adjacent delivery and collision audit

+- The active decisions are sequential and non-overlapping: ADR 0362 belongs to
+  the translation ledger, ADR 0363 to synchronous PostgreSQL TLS, ADR 0364 to
+  authenticated browser requests, and ADR 0365 to malformed Customer Master
+  hierarchy presentation. PR #911 alone adds the `2.28.0` changelog fragment;
+  #909 and #929 do not claim that release number.
+- The wider open queue still contains dependent report branches with serialized
+  release numbers and overlapping historical ADR-number ranges. Those branches
+  require ancestor-order convergence and a fresh exact-head ADR/API/schema/
+  release audit before merge. A clean local merge calculation or predecessor
+  check cannot transfer acceptance to a changed head.
+- PR #909 closes only the synthetic rendering gap: lint, focused regressions,
+  Storybook build, and 320 x 568 plus desktop visual audits passed on its exact
+  head. Authenticated PostgreSQL/API and deployed UI evidence are absent, so the
+  product acceptance condition remains explicitly unavailable.
+- Voice-of-X remains governed by ADR 0246/0251: the twelve atomic Voice classes
+  stay extensible through evidence-backed combinations. Carrying Posts and
+  derivation evidence remain distinct; hidden evidence is never substituted;
+  truth status, cutoff, PROV-O derivation, exact-value UI/CSV, and paged JSON-LD
+  subject merging are unchanged by these three candidates.
