### Task T001 - Verify analyzer state and session scope

**Started**: 2026-06-21 02:00 **Completed**: 2026-06-21 02:00 **Duration**: 1 minute

**Notes**:

* Confirmed analyzer current session is `phase29-session12-security-lens`.
* Confirmed Phase 29 is in progress, Session 12 is not yet completed, and prerequisite sessions are present in completed session state.
* Confirmed the session stub scope matches the spec: security relevance over existing evidence, Workbench filter, static Brief callout, payload safety, and no new source.

**Files Changed**:

* `.spec_system/specs/phase29-session12-security-lens/tasks.md` - Marked setup verification complete.
* `.spec_system/specs/phase29-session12-security-lens/implementation-notes.md` - Logged verification results.

***

### Task T002 - Inspect existing derivation and surface patterns

**Started**: 2026-06-21 02:00 **Completed**: 2026-06-21 02:00 **Duration**: 1 minute

**Notes**:

* Read source-breakdown derivation, reviewed keyword-pack rotation, schema defaults, Workbench model/control/table projection, Brief export, static Brief export/render/QA, payload-size reporting, fixtures, and focused test patterns.
* Confirmed `security` already exists as a reviewed keyword category and can be reused without source declaration changes.
* Confirmed required derived topic closeout uses both schema registration and `scripts/extensions/trend-finder/required-derived-fields.ts` shape checks.
* Confirmed static Brief QA requires a rendered `data-static-brief-section` marker for each report section.

**Files Changed**:

* `.spec_system/specs/phase29-session12-security-lens/tasks.md` - Marked pattern inspection complete.
* `.spec_system/specs/phase29-session12-security-lens/implementation-notes.md` - Logged implementation orientation.

***

### Task T003 - Create security-lens helper contract

**Started**: 2026-06-21 02:00 **Completed**: 2026-06-21 02:01 **Duration**: 1 minute

**Notes**:

* Added a deterministic `security-lens` helper with schema-validated input, bounded evidence pagination, bounded citations, severity selection, reason-code ordering, action-item ordering, and explicit unavailable output.
* Limited matching to existing normalized topic/evidence/source text and the reviewed security keyword category.
* Added privacy guards that skip private-looking raw markers, redacted secrets, prompts, transcripts, raw responses, and raw source/body markers.

**Files Changed**:

* `scripts/lib/ai-runtime/security-lens.ts` - Added helper contract, matching rules, bounded output, and unavailable fallback.

**BQC Fixes**:

* Trust boundary enforcement: validated helper input and output with Zod schemas (`scripts/lib/ai-runtime/security-lens.ts`).
* Error information boundaries: private-looking fields are not matched or cited (`scripts/lib/ai-runtime/security-lens.ts`).
* Contract alignment: verified script typecheck after adding helper and schema contracts.

***

### Task T004 - Add security relevance schema and closeout registration

**Started**: 2026-06-21 02:00 **Completed**: 2026-06-21 02:01 **Duration**: 1 minute

**Notes**:

* Added security relevance statuses, severity bands, reason codes, action-item constants, unavailable reasons, limits, default object, schema branch, and type export.
* Registered `securityRelevance` on topics with `.default()` and `.catch()` legacy fallbacks.
* Added cited-evidence validation so security relevance citations must exist and belong to the topic evidence set.
* Registered the field in required derived topic closeout and shape checks.

**Files Changed**:

* `src/extensions/trend-finder/schema.ts` - Added constants, schema, topic field, default, validation, and required derived registration.
* `scripts/extensions/trend-finder/required-derived-fields.ts` - Added required field shape for closeout checks.
* `src/extensions/trend-finder/fixtures.ts` - Added fixture builder default for the new derived field.

**BQC Fixes**:

* Contract alignment: schema defaults preserve legacy payload parsing while closeout still requires generated payloads to emit the field.
* Failure path completeness: invalid security citations produce schema issues instead of silent acceptance.

***

### Task T005 - Add security relevance view-model helpers

**Started**: 2026-06-21 02:01 **Completed**: 2026-06-21 02:02 **Duration**: 1 minute

**Notes**:

* Added security severity, reason, action-item, unavailable-reason labels and tone helpers.
* Added action-item chip, reason chip, citation, and topic-level security relevance view models.
* Added export-safe citation projection that only emits sanitized title/source labels and public URLs.
* Attached the security view model to the derived-signals view model.

**Files Changed**:

* `src/extensions/trend-finder/view-model.ts` - Added security lens labels, tones, summaries, chips, citations, and derived-signal projection.

**BQC Fixes**:

* Error information boundaries: citation projection sanitizes display text and drops non-public URLs.
* Contract alignment: view-model fallback uses `DEFAULT_TREND_SECURITY_RELEVANCE` for legacy topics.

***

### Task T006 - Add source-breakdown security relevance integration

**Started**: 2026-06-21 02:02 **Completed**: 2026-06-21 02:03 **Duration**: 1 minute

**Notes**:

* Wired deterministic security relevance derivation into topic source-breakdown enrichment while topic, evidence, and source maps are already in scope.
* Added an explicit unavailable fallback for derivation errors so unrelated topic output is not blocked.
* Verified script typechecking after integration.

**Files Changed**:

* `scripts/lib/ai-runtime/source-breakdown.ts` - Added security relevance derivation and unavailable fallback integration.

**BQC Fixes**:

* Failure path completeness: derivation errors degrade to explicit unavailable output instead of silently dropping the field.
* Contract alignment: fallback output is parsed through `TrendSecurityRelevanceSchema`.

***

### Task T007 - Add Signal Workbench security model support

**Started**: 2026-06-21 02:14 **Completed**: 2026-06-21 02:16 **Duration**: 2 minutes

**Notes**:

* Added `securitySeverity` filter state, default filter value, severity facets, row scalar fields, search indexing, summary count, and sort support.
* Projected security relevance through the shared view-model helper so Workbench rows use sanitized labels, summaries, action chips, and citation labels.
* Added stale-filter revalidation so a selected security severity resets to `all` when a new run payload no longer contains matching rows.
* Verified `bun run typecheck:scripts` and `bun run typecheck`.

**Files Changed**:

* `src/extensions/trend-finder/signal-workbench-model.ts` - Added security filter, facets, summaries, row fields, search, sort, and revalidation support.

**BQC Fixes**:

* State freshness on re-entry: security severity filter resets when the loaded row set cannot satisfy the selected value.
* Error information boundaries: row search and display fields use sanitized view-model output instead of raw evidence text.
* Contract alignment: Workbench row and facet types now include the new schema severity taxonomy.

***

### Task T008 - Reuse reviewed security keyword category

**Started**: 2026-06-21 02:16 **Completed**: 2026-06-21 02:18 **Duration**: 2 minutes

**Notes**:

* Added a named `TREND_FINDER_SECURITY_KEYWORD_CATEGORY_ID` and `getReviewedSecurityKeywordCategory` accessor for the existing reviewed `security` keyword category.
* Updated the security-lens helper to consume the named accessor instead of directly resolving a string category id.
* Left keyword content and source declarations unchanged.
* Verified `bun run typecheck:scripts`.

**Files Changed**:

* `scripts/extensions/trend-finder/sources/keyword-packs.ts` - Added named security category id/accessor without changing reviewed keyword contents.
* `scripts/lib/ai-runtime/security-lens.ts` - Reused the named reviewed security category accessor.

**BQC Fixes**:

* Contract alignment: security lens matching now depends on an explicit reviewed category accessor rather than an ad hoc string lookup.

***

### Task T009 - Implement bounded security evidence matching

**Started**: 2026-06-21 02:18 **Completed**: 2026-06-21 02:18 **Duration**: 1 minute

**Notes**:

* Confirmed security matching reads only normalized topic name/summary/why-now, evidence title/snippet, and source label/type/role/quality fields.
* Confirmed helper options are schema-validated, topic evidence IDs are de-duplicated and capped, private-looking text is skipped, and match ordering is deterministic by severity, score, relevance, and evidence id.
* Confirmed reviewed security keywords are used as one signal rather than adding new source access.
* Verified `bun run typecheck:scripts` after the helper/accessor changes.

**Files Changed**:

* `scripts/lib/ai-runtime/security-lens.ts` - Provides bounded matching, privacy guards, deterministic ordering, and schema-validated options.

**BQC Fixes**:

* Trust boundary enforcement: helper input/options are validated before matching.
* Error information boundaries: private markers, redacted strings, prompts, transcripts, raw responses, raw source markers, and comment/body markers are skipped.
* Contract alignment: matches cite existing topic evidence IDs only.

***

### Task T010 - Implement security severity and informational actions

**Started**: 2026-06-21 02:18 **Completed**: 2026-06-21 02:19 **Duration**: 1 minute

**Notes**:

* Confirmed severity selection uses fixed precedence across critical, high, medium, low, and unavailable.
* Confirmed named action items come only from the bounded security action taxonomy and are capped by schema-validated options.
* Confirmed summaries and action labels stay informational and do not instruct automated remediation or execution.
* Verified `bun run typecheck:scripts` after the helper/accessor changes.

**Files Changed**:

* `scripts/lib/ai-runtime/security-lens.ts` - Provides severity selection, reason bounds, action-item bounds, and informational summary output.

**BQC Fixes**:

* Contract alignment: output is parsed through `TrendSecurityRelevanceSchema` and uses only exported security reason/action/severity enums.
* Error information boundaries: generated summaries reference severity/reason categories and citation counts, not raw matched text.

***

### Task T011 - Project security relevance into Brief export documents

**Started**: 2026-06-21 02:19 **Completed**: 2026-06-21 02:21 **Duration**: 2 minutes

**Notes**:

* Added a `securityLens` section to the Brief export document with available, empty, and unavailable states.
* Projected security rows with sanitized topic names, severity labels, reason summaries, bounded informational action labels, citation counts, and cited evidence labels/URLs.
* Added a Markdown `Security Lens` section and summary metric.
* Verified `bun run typecheck` and `bun test ./src/extensions/trend-finder/__tests__/brief-export-model.test.ts`.

**Files Changed**:

* `src/extensions/trend-finder/brief-export-model.ts` - Added security lens projection and Markdown output.

**BQC Fixes**:

* Error information boundaries: security rows use shared sanitized view-model labels plus Brief export redaction and safe public URL filtering.
* Contract alignment: rows are sorted by bounded severity taxonomy and cite existing evidence labels only.

***

### Task T012 - Add security lens to static Brief report contract

**Started**: 2026-06-21 02:21 **Completed**: 2026-06-21 02:25 **Duration**: 4 minutes

**Notes**:

* Added static Brief security lens limits, default unavailable state, Zod schemas, and report contract field.
* Added projection for available, empty, and unavailable security lens states with bounded rows, action labels, severity labels, citation labels, and safe public citation URLs.
* Hardened static export string limiting so non-string rationale-like values cannot flow into string schema fields.
* Verified `bun run typecheck:scripts` and `bunx vitest run ./scripts/extensions/trend-finder/__tests__/static-brief-export.test.ts`.

**Files Changed**:

* `scripts/extensions/trend-finder/static-brief-export.ts` - Added security lens schema/projector/report field and hardened string limiting.

**BQC Fixes**:

* Trust boundary enforcement: static report output is schema-parsed with the new security lens branch.
* Error information boundaries: security citations use safe public URL filtering and sanitized labels; non-string projected text is dropped before redaction.
* Failure path completeness: empty and unavailable security lens states are explicit in the static report contract.

***

### Task T013 - Add Signal Workbench security filter controls

**Started**: 2026-06-21 02:25 **Completed**: 2026-06-21 02:27 **Duration**: 2 minutes

**Notes**:

* Added a labelled native `Security` severity select to Signal Workbench controls using the existing accessible filter control pattern.
* Reused model facets and filter state so reset and run re-entry revalidation continue through the existing Workbench view flow.
* Verified `bun run typecheck` and `bunx vitest run ./src/extensions/trend-finder/components/__tests__/signal-workbench-view.test.tsx`.

**Files Changed**:

* `src/extensions/trend-finder/components/signal-workbench-controls.tsx` - Added the security severity filter select.

**BQC Fixes**:

* Accessibility and platform compliance: security filtering uses a labelled native select with keyboard support.
* State freshness on re-entry: control uses the model filter state that is revalidated when the loaded rows change.

***

### Task T014 - Render Signal Workbench security chips

**Started**: 2026-06-21 02:27 **Completed**: 2026-06-21 02:28 **Duration**: 1 minute

**Notes**:

* Added a sortable security severity column to the Workbench table.
* Added compact security severity and bounded informational action chips to topic rows and expanded detail metrics.
* Updated fixed table width and column spans for the additional column.
* Verified `bun run typecheck` and `bunx vitest run ./src/extensions/trend-finder/components/__tests__/signal-workbench-view.test.tsx`.

**Files Changed**:

* `src/extensions/trend-finder/components/signal-workbench-table.tsx` - Added security severity/action chips, sort column, and table span updates.

**BQC Fixes**:

* Accessibility and platform compliance: chips include security-specific aria labels and the sortable header participates in the existing `aria-sort` pattern.
* Contract alignment: chips consume bounded action item view models and severity tone from the Workbench row model.

***

### Task T015 - Render static Brief security lens callout

**Started**: 2026-06-21 02:28 **Completed**: 2026-06-21 02:29 **Duration**: 1 minute

**Notes**:

* Added a static Brief `Security Lens` details section with a `data-static-brief-section="security-lens"` marker.
* Rendered explicit empty state, severity tag, reason/action tags, citation count, and bounded cited evidence links with safe public URL filtering.
* Verified `bun run typecheck:scripts` and `bunx vitest run ./scripts/extensions/trend-finder/__tests__/static-brief-renderer.test.ts`.

**Files Changed**:

* `scripts/extensions/trend-finder/static-brief-renderer.ts` - Added security lens renderer and main page section.

**BQC Fixes**:

* Error information boundaries: renderer escapes all security text and filters citation URLs through the existing public URL guard.
* Accessibility and platform compliance: section and cards carry aria labels from the sanitized static report contract.

***

### Task T016 - Add static Brief QA for security lens

**Started**: 2026-06-21 02:29 **Completed**: 2026-06-21 02:32 **Duration**: 3 minutes

**Notes**:

* Added `security-lens` to the rendered-section QA marker list and section labels.
* Added QA checks for available security rows with missing rows, unavailable severities, action/citation bound overruns, and missing cited evidence details.
* Added a focused static Brief QA test for missing security citations and private-string failure mapping.
* Verified `bun run typecheck:scripts` and `bunx vitest run ./scripts/extensions/trend-finder/__tests__/static-brief-qa.test.ts ./scripts/extensions/trend-finder/__tests__/static-brief-export.test.ts`.

**Files Changed**:

* `scripts/extensions/trend-finder/static-brief-qa.ts` - Added security section marker and row structure checks.
* `scripts/extensions/trend-finder/__tests__/static-brief-qa.test.ts` - Added security lens QA failure coverage.
* `scripts/extensions/trend-finder/__tests__/static-brief-export.test.ts` - Updated checked-section count for the new section.

**BQC Fixes**:

* Failure path completeness: malformed security lens rows map to explicit blocking QA issues.
* Error information boundaries: privacy scans now cover security lens report and rendered HTML content.

***

### Task T017 - Add payload-size tracking for security relevance

**Started**: 2026-06-21 02:32 **Completed**: 2026-06-21 02:33 **Duration**: 1 minute

**Notes**:

* Added `data.topics[].securityRelevance` to payload-size always-included high-pressure branches.
* Added missing-field summary row and nested field breakdown for topic security relevance.
* Extended payload-size test coverage for legacy payloads where the branch is absent.
* Verified `bun run typecheck:scripts` and `bunx vitest run ./scripts/extensions/trend-finder/__tests__/measure-payload-size.test.ts`.

**Files Changed**:

* `scripts/extensions/trend-finder/measure-payload-size.ts` - Added security relevance branch and nested field tracking.
* `scripts/extensions/trend-finder/__tests__/measure-payload-size.test.ts` - Added branch visibility assertion.

**BQC Fixes**:

* Contract alignment: payload reports include the new required derived topic branch even when legacy data omits it.

***

### Task T018 - Document security-lens pipeline behavior

**Started**: 2026-06-21 02:33 **Completed**: 2026-06-21 02:34 **Duration**: 1 minute

**Notes**:

* Documented security relevance as a deterministic derived lens over existing normalized evidence.
* Documented reviewed security keyword reuse, unavailable states, source/privacy boundaries, required closeout, payload-size visibility, and static Brief projection behavior.
* Updated pipeline step descriptions and implementation map.

**Files Changed**:

* `docs/extensions/trend-finder-pipeline.md` - Added security lens derivation and boundary documentation.

**BQC Fixes**:

* Contract alignment: documentation now matches the generated payload closeout requirement and shipped static Brief payload behavior.

***

### Task T019 - Document shipped UI behavior

**Started**: 2026-06-21 02:34 **Completed**: 2026-06-21 02:37 **Duration**: 3 minutes

**Notes**:

* Documented the Signal Workbench security severity filter, sortable security column, row chips, expanded-row labels, and unavailable empty-state behavior as shipped UI.
* Documented the Brief and static Brief security lens callout as a display-only projection over existing normalized evidence.
* Made the source boundary explicit: no new security feed, article body/comment/transcript reads, scans, remediation, score mutation, or source declaration changes.

**Files Changed**:

* `docs/extensions/trend-finder-ui-surfaces.md` - Added shipped Workbench and static Brief security lens behavior.

**BQC Fixes**:

* Contract alignment: UI documentation now matches the implemented Workbench filter and static Brief security callout.
* Error information boundaries: docs state that the lens uses browser-safe derived fields and does not expose raw/private source payloads.

***

### Task T020 - Add security lens runtime tests

**Started**: 2026-06-21 02:37 **Completed**: 2026-06-21 02:39 **Duration**: 2 minutes

**Notes**:

* Added direct security-lens tests for available security fixtures, non-security unavailable output, severity/action/citation bounds, deterministic citation ordering, and private-looking text rejection.
* Added source-breakdown integration coverage proving security relevance is attached during topic enrichment and private-looking evidence text is not cited or echoed.
* Verified focused Vitest coverage for the new helper and source-breakdown integration.

**Files Changed**:

* `scripts/lib/ai-runtime/__tests__/security-lens.test.ts` - Added direct security-lens helper coverage.
* `scripts/lib/ai-runtime/__tests__/source-breakdown.test.ts` - Added security relevance integration and privacy coverage.

* Error information boundaries: tests assert private-looking prompts/raw response markers are skipped and not serialized.
* Contract alignment: tests lock bounded reason, action, and citation behavior.

**Verification**:

* `bunx vitest run ./scripts/lib/ai-runtime/__tests__/security-lens.test.ts ./scripts/lib/ai-runtime/__tests__/source-breakdown.test.ts`

***

### Task T021 - Add schema, view-model, and Workbench tests

**Started**: 2026-06-21 02:39 **Completed**: 2026-06-21 02:41 **Duration**: 2 minutes

**Notes**:

* Added schema coverage for legacy topic payloads missing `securityRelevance` and required-derived topic registration.
* Added security view-model coverage for labels, action summaries, public citation URLs, private URL filtering, and unavailable empty states.
* Added Workbench model coverage for security severity row fields, action chips, filters, facets, search indexing, sorting, summary counts, and stale-filter revalidation.

**Files Changed**:

* `src/extensions/trend-finder/__tests__/signal-workbench-model.test.ts` - Added security schema, view-model, and Workbench model coverage.

**BQC Fixes**:

* Contract alignment: tests lock legacy schema defaults and required-derived registration.
* State freshness on re-entry: tests lock security filter reset when selected severity is absent.
* Error information boundaries: tests lock browser-safe citation URL projection for the view model.

**Verification**:

* `bunx vitest run ./src/extensions/trend-finder/__tests__/signal-workbench-model.test.ts`

***

### Task T022 - Add static Brief security tests

* Added renderer assertions for the Security Lens section marker, severity/action content, public evidence links, and filtering of unsafe citation URLs.
* Extended static Brief QA coverage for over-bound security action and evidence rows.
* Added payload-size coverage for nested `data.topics[].securityRelevance` field reporting when the branch is present.

**Files Changed**:

* `scripts/extensions/trend-finder/__tests__/static-brief-export.test.ts` - Added security lens export assertions.
* `scripts/extensions/trend-finder/__tests__/static-brief-renderer.test.ts` - Added security callout rendering assertions.
* `scripts/extensions/trend-finder/__tests__/static-brief-qa.test.ts` - Added security bounds QA assertions.
* `scripts/extensions/trend-finder/__tests__/measure-payload-size.test.ts` - Added nested security branch size assertion.

* Failure path completeness: tests lock QA failures for missing and over-bound security evidence/action details.
* Contract alignment: tests lock payload-size visibility for present and absent security relevance branches.

**Verification**:

* `bunx vitest run ./scripts/extensions/trend-finder/__tests__/static-brief-export.test.ts ./scripts/extensions/trend-finder/__tests__/static-brief-renderer.test.ts ./scripts/extensions/trend-finder/__tests__/static-brief-qa.test.ts ./scripts/extensions/trend-finder/__tests__/measure-payload-size.test.ts`

***

### Task T023 - Run final verification

**Started**: 2026-06-21 02:44 **Completed**: 2026-06-21 02:48 **Duration**: 4 minutes

**Notes**:

* Ran script and app typechecks successfully.
* Ran the focused runtime, Workbench, Brief export, static Brief, payload-size, and required-derived-field Vitest suites successfully.
* Ran payload-size reporting against `src/data/live-data.json`; the current checked-in payload is below the browser payload boundary, but predates this session and reports `data.topics[].securityRelevance` as a 0-byte missing branch.
* Ran static Brief CLI dry-run against the validated static Brief fixture with QA/privacy passing.
* Attempted static Brief CLI dry-run against `src/data/live-data.json`; it failed required-derived closeout because that checked-in payload is stale and missing `runNarratives`, `industryEvents`, and new per-topic `securityRelevance` branches.
* Ran ASCII validation across changed and untracked session files with no non-ASCII matches.

**Files Changed**:

* `.spec_system/specs/phase29-session12-security-lens/tasks.md` - Marked T023 and completion checklist complete.
* `.spec_system/specs/phase29-session12-security-lens/implementation-notes.md` - Logged final verification.

**BQC Fixes**:

* Contract alignment: final typechecks and focused suites confirm the schema, runtime, UI, export, QA, and payload-size contracts agree.
* Failure path completeness: stale generated live-data failure is explicit and points to required-derived closeout rather than a silent static Brief export.
* Error information boundaries: static Brief fixture dry-run QA/privacy passes and changed-file ASCII scan is clean.

**Verification**:

* `bun run typecheck:scripts`
* `bun run typecheck`
* `bunx vitest run ./scripts/lib/ai-runtime/__tests__/security-lens.test.ts ./scripts/lib/ai-runtime/__tests__/source-breakdown.test.ts ./src/extensions/trend-finder/__tests__/signal-workbench-model.test.ts ./src/extensions/trend-finder/__tests__/brief-export-model.test.ts ./src/extensions/trend-finder/components/__tests__/signal-workbench-view.test.tsx ./scripts/extensions/trend-finder/__tests__/static-brief-export.test.ts ./scripts/extensions/trend-finder/__tests__/static-brief-renderer.test.ts ./scripts/extensions/trend-finder/__tests__/static-brief-qa.test.ts ./scripts/extensions/trend-finder/__tests__/measure-payload-size.test.ts ./scripts/extensions/trend-finder/__tests__/required-derived-fields.test.ts`
* `bun run scripts/extensions/trend-finder/measure-payload-size.ts src/data/live-data.json --threshold-kb=9999 --json`
* `bun run trend-finder:export-brief -- --input <fixture-live-data> --output <temp-out> --dry-run --json`
* ASCII scan of changed and untracked session files
