[Unreleased]

Fixed

• Static review-document footers now link to the existing browser-rendered licence and attribution notice instead of the extensionless repository LICENSE path. This keeps the MIT boundary visible in browsers that block extensionless file responses, without changing corpus or semantic bytes.

Added

• Governed static-document publication through validated frontmatter, deterministic safe HTML, an automatically generated document index and a source-to-output SHA-256 manifest. A changed-path dependency gate permits a smaller local validation route only when the diff is confined to the documentation overlay and fails closed for corpus, semantic, schema, workflow or other changes. The draft product requirements are nominated and rendered for the review library. Pull requests and merges remain publication-free; the frozen corpus is not rebuilt or modified. The base transporter now recovers a drifted documentation handoff from the exact verified publication commit, preventing later repository documentation from changing any manifest-bound base byte.

• HTML-first AI retrieval layer generated deterministically from the governed journey projection: one compact catalogue and 293 complete family records carrying stable IDs, explicit applicability, ordinary and exception steps, official source URLs, provenance, review state and limitations. This fixes a public-review finding in which Microsoft 365 Copilot could retrieve short narrative material but not the 7.2 MB raw projection, and therefore correctly abstained on several requested fields. The full projection remains unchanged as the canonical audit artefact. Provider-neutral prompts now use catalogue selection followed by one small complete record, with a visible save-and-attach fallback for approved organisational use.

• Owner-authorised Explore OKF public-review surface comprising the root explore-okf.json descriptor, secure standalone en-GB journey view, governed projection and schema, endpoint-label index, data manifest, review hub and a curated beginner-readable documentation library. The overlay replaces only the root landing page after matching its frozen SHA-256 and adds all other review targets without changing the exact okf-explorer.json descriptor or any corpus and relationship-runtime byte. The documentation- only re-freeze synchronises affected browser handoffs and their manifest bindings. The interface exposes all 293 families, 24 domains, 48 processes, 586 episodes, 881 steps and 879 linked official sources with explicit ordering, jurisdiction, review and provenance boundaries. Local deterministic build/check, publication- overlay, documentation, schema, security and unit validation pass. The surface remains exploratory, noindex and not release-grade; exact public URLs remain unverified until the authorised deployment passes browser checks. The learning route includes provider-neutral copy-and-paste AI prompts that use direct public entry points, require evidence-bearing answers and abstention, warn against personal information and treat embedded commands as untrusted data rather than executable instructions. British English is used throughout affected prose; exact schema values, identifiers and legacy filenames retain their contract spellings.

• Provider-neutral AI-consumer gold pack, structured answer contract, bounded offline evaluator and isolated two-condition runner for all 104 governed competency questions. The answer-blind development preflight records exact runner, prompt, schema, question-source, descriptor, projection and publication-closure identities. Local answer-blind development runs were used to diagnose prompt, jurisdiction and decision-boundary ambiguities; the receipt boundary does not support a published behavioural result. Two later no-retry comparison attempts were preserved privately and stopped before completion. The evaluator does not yet bind each supplied answer to its immutable runner receipt, so no response counts, scores or model comparison from those attempts are published as evidence. Raw model prose and run artefacts remain ignored. All 104 questions are now development-calibration material, promotion claims are disabled, and a new held-out set, receipt binding and independent review are required for any future performance or product-promotion claim.

• A 1,814-file publication freeze for the rich relationship runtime generated at reviewed main commit c38f927…. The manifest pins every served SHA-256, 262 rich-runtime files and the updated population-assurance identity without changing semantic authority, corpus scope, release grade or the zero-snapshot boundary. The manual workflow now requires the exact protected-main merge commit and will not deploy on a pull request or ordinary merge.

• Cross-repository OKF 0.2 semantic contract in okf.semantic.json plus repository-local agent guidance for the additive Bundle Wiki YAML-LD profile. The deterministic large-corpus build now emits all 15,810 directed relationships with absolute entity, predicate and assertion IRIs, validated local routes, preferred and inverse labels, status, scope, authority, derivation, observation time, evidence and rights. The YAML-LD/JSON-LD graph carries both each direct triple and its evidence-bearing reified assertion; a digest-pinned local copy of the shared Draft 2020-12 assertion schema now validates all 15,810 semantic assertions and all 15,810 runtime rows before a conformance receipt can be emitted. The finalized pin requires both kind and label and canonical, credential-free HTTP(S) authority, evidence, evidence-resource and rights URLs. The canonical 16-file profile is now vendored with its digest lock, and the canonical assertion schema is pinned byte for byte. Explorer can hydrate the same assertions from two bounded, active authority planes through digest-bound gzip shards and a SHA-256 route locator whose per-plane commitments cover every incident assertion. Projection checks and the full unit suite pass. This local regeneration does not modify or republish the frozen population preview.

• Public deployment evidence for workflow run 31297841419, deployment 5815993749, the exact manifest and descriptor hashes, and the verified search-to-GOV.UK Explorer journey.
• Server-enforced sole-developer main protection requiring pull requests and resolved conversations while requiring zero approvals or remote checks.

Changed

• Repository visibility changed from private to public after explicit owner authorisation, exposing the complete source and history and unblocking Pages.
• PAGES-001, VERIFY-001 and the verified preview handoff are complete; the preview remains non-release-grade and the Explorer UI findings remain open.

• Publication authorisation remains a separate descriptor envelope and dated receipt so that the owner-authorised candidate bytes and hash are unchanged.
• Manual Pages transport and local publication validation now pin publication merge 980c7a9…, so later lockstep documentation cannot alter the frozen 1,549-file unit.
• PAGES-001 is blocked on an explicit repository-visibility/publication-host choice; conversational search, zero-result domain browsing and display density remain tracked Explorer follow-ups.

• Completed SCOPE-001, CAND-001 and PUB-001 for the full population-complete preview after explicit owner authorisation; advanced PAGES-001 to active while public-browser verification remains pending.

• Completed ASSURE-001 after reconciling 293 families, 24 domains, 48 processes, 104 competency questions, 9,757 concepts, 879 resources and 15,810 relationships with zero blocking omissions. Population completion is true; release grade and publication remain false.
• Disposed all twelve historical reference gaps against the population gate while retaining named specialist review, reviewed freshness, bilingual and future-automation boundaries for later work.

• Advanced PACK-008 to complete and ASSURE-001 to active after the full 293-family, 9,757-concept, 879-resource and 15,810-relationship projection passed locked local validation and visible Explorer review.

• Advanced PACK-007 to complete and PACK-008 to active after the 255-family, 8,645-concept, 802-resource and 13,972-relationship projection passed locked local validation and visible Explorer review.

• Advanced PACK-006 to complete and PACK-007 to active after the 219-family, 7,613-concept, 761-resource and 12,377-relationship projection passed locked local validation and visible Explorer review.

• Advanced PACK-005 to complete and PACK-006 to active after the 183-family, 6,587-concept, 629-resource and 10,424-relationship projection passed locked local validation.

• Advanced PACK-004 to complete and PACK-005 to active after the 148-family, 5,567-concept, 524-resource and 8,599-relationship projection passed locked local validation.

• Advanced PACK-003 to complete and PACK-004 to active after the 113-family, 4,535-concept, 384-resource and 6,622-relationship projection passed locked local validation.

• Advanced PACK-002 to complete and PACK-003 to active after the 77-family, 3,496-concept, 300-resource and 4,850-relationship projection passed locked local validation.

• Advanced PACK-001 to complete and PACK-002 to active after the 42-family, 2,485-concept, 160-resource and 2,894-relationship projection passed all deterministic and visible-browser checks.
• Replaced six-family/53-resource projection assertions with current-stage reconciliation derived from authored dossiers and 1,000-record chunks.

• Expanded dated host decisions from 25 to 28 for the ONS Open Geography portal, its ArcGIS query service and the ESD standards help service without relaxing link-and-summary-only source use.
• Advanced POP-004 to complete after offline validation, live metadata receipts and local Explorer search, detail, bilingual and graph journeys.

• Recorded OKF Explorer PR #72 as merged with authored large-record narratives and typed link/JSON/XML/text source access after the full three-browser gate.
• Replaced the planning-only zero-resource and zero-relationship projection for the six reviewed families while preserving all 293 family routes and distinct family versus total-concept counts.

• Superseded the three-slices-only implementation boundary with the explicit 2026-08-08 owner authorisation for the staged 293-family population while keeping link-and-summary-only acquisition, local evaluation and no Pages publication.

• Recorded owner approval of okf-domain-profile.v1 and the three fixture contracts, authorising bounded source registration and slice implementation.
• Connected the explicitly authorised private GitHub repository while keeping remote CI and GitHub Pages disabled.
• Recorded the private-plan branch-protection limitation while retaining the sole-developer PR-only policy for main.
• Advanced the missed-rubbish fixture acquisition state to linked_references_registered.
• Advanced the driving fixture to linked_references_registered before its implementation merged in PR #4.
• Recorded PR #4 as merged and advanced the bereavement fixture to linked_references_registered; all three approved denominators are now registered.
• Replaced pending reuse markers with recorded source-family decisions while retaining link-and-summary-only use and prohibiting source-content and snapshot redistribution.
• Recorded PR #5 and PR #6 as merged and advanced the bounded sample to integrated review, while keeping publication separately gated.
• Executed the first visible-browser integrated review, recording four real provenance, source-handoff and licence-notice failures that were subsequently remediated and closed by the local rerun.
• Expanded dated rights decisions from 16 to 25 source hosts and added ONS, NHS ODS, W3C, LGSL and OKF Explorer determinations without relaxing link-and-summary-only source use or authorising publication.
• Recorded explicit owner authorisation for exhaustive link-only reference discovery while preserving the snapshot, redistribution, unbounded or unstaged leaf acquisition, CI and GitHub Pages gates.
• Recorded owner approval of all six corpus-governance decisions while keeping individual legal and clinical appointments, CI and publication separately gated.
• Locked the small-bundle Explorer consumer contract for local evaluation and activated the large-corpus approval after all four prerequisites passed.
