### Metadata Additions

* T006 added `countSummary` and `dreamFieldPolicy` to `PublicDemoSnapshotMetadata`. Because the manifest extends metadata, both `snapshot-metadata.json` and `snapshot-manifest.json` carry the same count summary and Dream field-policy evidence.
* Count summaries are computed from the sanitized projected LiveData output, not from raw input.
* Dream field policy records the current `not-exported` state and routes the allowlist projection to `phase33-session04-harden-dream-projection`.

***

## Fixture Write Results

* T008 pre-write focused exporter test passed before dry-run or final fixture write.
* T009 dry-run passed with no files written. Captured timestamp: `2026-06-25T01:18:58.994Z`; source commit: `95cd61a49ecd`; route coverage count: 24; scan status: `pass`; issue count: 0.
* T011 final write passed. Captured timestamp: `2026-06-25T01:21:06.085Z`; source commit: `95cd61a49ecd`; scan status: `pass`; issue count: 0; routes covered: 24; exporter reported 5 files written.
* T012 and T013 post-write fixture, metadata, and manifest reviews completed.

***

## Privacy Scan Results

* T009 dry-run in-memory scan passed with issue count 0.
* T014 committed-fixture privacy scan passed: 5 scanned, 0 skipped, 0 issues.
* T015 focused post-write snapshot and privacy tests passed: 2 files, 18 tests.

***

## Static Pages Boundary Evidence

* T003: `package.json` keeps `demo:snapshot`, `demo:build:pages`, and `demo:scan:pages` as separate scripts. `demo:build:pages` runs Vite in `demo-pages` mode and `scripts/demo/assemble-pages-dist.ts`; it does not call `demo:snapshot`, schedulers, aggregate, Dream runtime, uploads, or admin mutation commands.
* T016: `scripts/lib/pages-demo-build.ts` requires committed public fixture files (`demo/live-data.snapshot.json`, `demo/snapshot-metadata.json`, and `demo/graphs/index.json`) before assembling the Pages output. The build and assemble path has no `demo:snapshot`, snapshot exporter, scheduler, aggregate, Dream, upload, admin, mutation, or bridge invocation.

***

## Projection Caveats And Handoff

Known planning caveat: Session 02 freezes fixtures and records metadata/count evidence. Full Trend Finder projection hardening is reserved for Session 03, and full Dream Review allowlist projection is reserved for Session 04.

Final handoff:

* Session 03 should harden retained Trend Finder projection coherence for the trimmed topic/evidence rows, Engine Replay state, industry events, run narratives, and movement analyses.
* Session 04 should implement the Dream Review public fixture allowlist and positive/negative privacy coverage. Current public fixture state is `dream: null` with manifest policy `not-exported`.
* Session 05 can polish public demo UI states after Sessions 03 and 04 improve the projected fixture branches.
* Session 06 can run the bundled Pages build, budget, scan, smoke, and deploy gates.

***

## Final Implementation Summary

### Changed Files

* `scripts/lib/pages-demo-snapshot.ts` - added typed count-summary metadata, guarded count helpers, Dream field policy metadata, and metadata wiring.
* `scripts/lib/__tests__/pages-demo-snapshot.test.ts` - added deterministic metadata, count-summary, Dream field-policy, and persisted-manifest assertions.
* `demo-website/public/demo/live-data.snapshot.json` - regenerated public LiveData fixture through `bun run demo:snapshot`.
* `demo-website/public/demo/snapshot-metadata.json` - regenerated metadata with count summary and Dream field policy.
* `demo-website/snapshot-manifest.json` - regenerated review manifest with count summary, Dream field policy, and existing Trend Finder policy.
* `.spec_system/specs/phase33-session02-freeze-public-fixtures/tasks.md` - tracked task completion.
* `.spec_system/specs/phase33-session02-freeze-public-fixtures/implementation-notes.md` - recorded session evidence.
* `.spec_system/state.json` - already reflected the planning handoff: current session set to Session 02 and Session 02 recorded as planned.

The exporter reported writes for `demo-website/public/demo/graphs/index.json` and `demo-website/public/demo/graphs/ai-os.json`; both had no content diff.

### Command Outcomes

* `bun run typecheck:scripts` - PASS after exporter changes and after test changes.
* `bun run test -- scripts/lib/__tests__/pages-demo-snapshot.test.ts` - PASS, 1 file and 7 tests.
* `bun run demo:snapshot --dry-run --json` - PASS, dry-run true, no files written, route coverage 24, scan pass with 0 issues.
* `bun run demo:snapshot` - PASS, final write reported 5 files, route coverage 24, scan pass with 0 issues.
* `bun run demo:scan:pages --fixtures` - PASS, 5 scanned, 0 skipped, 0 issues.
* `bun run test -- scripts/lib/__tests__/pages-demo-snapshot.test.ts scripts/lib/__tests__/pages-demo-privacy-scan.test.ts` - PASS, 2 files and 18 tests.
* Final task-count sanity - PASS, 18 total tasks, 18 completed, 0 pending.
* `bunx prettier --write ...` - applied formatting to the touched source, test, and session Markdown files.
* `bunx prettier --check ...` - PASS, all matched files use Prettier style.
* JSON parse check - PASS, 5 generated JSON files.
* ASCII check - PASS, 10 checked files.
* LF line-ending check - PASS, 10 checked files.
* `git diff --check HEAD` - PASS.

### Count Deltas

* Selected input to generated public fixture: topics 9 -> 8; evidence 199 -> 16; sources 12 -> 12; watchlist 3 -> 3; predictions 9 -> 9; retrospectives 10 -> 10; story log 50 -> 12.
* Advanced/trace deltas: industry events 5 -> 0; run narratives 1 -> 0; movement analyses 9 -> 0; Engine Replay sanitized trace -> null public trace.
* Dream deltas: prescriptions 4 -> 0; tags 12 -> 0; public Dream policy is `not-exported`.

### Task T001 - Verify Phase 33 Session 02 prerequisites, Session 01 completion evidence, and static fixture boundary

**Started**: 2026-06-25 04:10 **Completed**: 2026-06-25 04:10 **Duration**: 1 minute

**Notes**:

* Confirmed `phase33-session02-freeze-public-fixtures` is the current session from the spec analyzer.
* Confirmed environment prerequisites and required tools pass: spec system, `jq`, `git`, and Bun 1.3.14.
* Reviewed the Session 02 phase stub and Session 01 validation evidence. Session 01 validated PASS with 16/16 tasks complete and selected local capture evidence present.
* Confirmed Session 02 scope remains static fixture freezing and review metadata, with Cloudflare deployment and runtime behavior out of scope.

**Files Changed**:

* `.spec_system/specs/phase33-session02-freeze-public-fixtures/implementation-notes.md` - created session log and recorded setup verification evidence.

**Verification**:

* Command/check: `if [ -d ".spec_system/scripts" ]; then bash .spec_system/scripts/analyze-project.sh --json; else bash /home/aiwithapex/.codex/plugins/cache/apex-spec-system/apex-spec/2.1.3-codex/skills/apex-spec/scripts/analyze-project.sh --json; fi`
  * Result: PASS - current session resolved to `phase33-session02-freeze-public-fixtures`; session directory exists; monorepo detection is false.
  * Evidence: Analyzer output reported current phase 33, current session `phase33-session02-freeze-public-fixtures`, and candidate Session 02 incomplete.
* Command/check: `if [ -d ".spec_system/scripts" ]; then bash .spec_system/scripts/check-prereqs.sh --json --env; else bash /home/aiwithapex/.codex/plugins/cache/apex-spec-system/apex-spec/2.1.3-codex/skills/apex-spec/scripts/check-prereqs.sh --json --env; fi`
  * Result: PASS - environment checks passed.
  * Evidence: `overall` was `pass`; spec system, `jq`, and `git` checks passed.
* Command/check: `if [ -d ".spec_system/scripts" ]; then bash .spec_system/scripts/check-prereqs.sh --json --tools "bun,jq,git"; else bash /home/aiwithapex/.codex/plugins/cache/apex-spec-system/apex-spec/2.1.3-codex/skills/apex-spec/scripts/check-prereqs.sh --json --tools "bun,jq,git"; fi`
  * Result: PASS - tool checks passed.
  * Evidence: Bun 1.3.14, jq 1.7, and git 2.43.0 were available.
* Command/check: `sed -n '1,260p' .spec_system/specs/phase33-session01-capture-local-demo-runs/validation.md`
  * Result: PASS - Session 01 validation result is PASS.
  * Evidence: Validation summary records 16/16 tasks complete, deliverables present, tests passing, and no unresolved blockers.
* UI product-surface check: N/A - setup verification only; no user-facing surface changed.
* UI craft check: N/A - setup verification only; no UI changed.

**BQC Fixes**:

* N/A - setup verification only; no application code changed.

### Task T002 - Create implementation notes sections for fixture-freeze evidence

**Started**: 2026-06-25 04:10 **Completed**: 2026-06-25 04:11 **Duration**: 1 minute

**Notes**:

* Created dedicated implementation-notes sections for commands, input counts, dry-run projected counts, fixture writes, generated output counts, privacy scans, static Pages boundary evidence, projection caveats, and Session 03/04 handoff notes.
* Kept the evidence format count-only by default so later entries can record fixture presence without copying private payload bodies.

**Files Changed**:

* `.spec_system/specs/phase33-session02-freeze-public-fixtures/implementation-notes.md` - added the session scaffold and T001/T002 evidence areas.

**Verification**:

* Command/check: `sed -n '1,220p' .spec_system/specs/phase33-session02-freeze-public-fixtures/implementation-notes.md`
  * Result: PASS - required implementation-note sections are present.
  * Evidence: Sections exist for commands, selected input counts, current public snapshot counts, dry-run projected counts, generated fixture counts, fixture write results, privacy scan results, static Pages boundary evidence, projection caveats, and task log entries.
* UI product-surface check: N/A - session artifact only; no user-facing surface changed.
* UI craft check: N/A - session artifact only; no UI changed.

**BQC Fixes**:

* N/A - session artifact only; no application code changed.

### Task T003 - Verify snapshot, build, and scan command separation before fixture work

**Started**: 2026-06-25 04:11 **Completed**: 2026-06-25 04:11 **Duration**: 1 minute

**Notes**:

* Confirmed fixture authoring remains an explicit local operator command through `demo:snapshot`.
* Confirmed Pages build assembly uses committed public fixture files and is not wired to snapshot authoring, scheduler, aggregate, Dream, upload, or admin mutation commands.
* Confirmed fixture privacy scanning is a separate command through `demo:scan:pages`.

**Files Changed**:

* `.spec_system/specs/phase33-session02-freeze-public-fixtures/implementation-notes.md` - recorded static command-boundary evidence.

**Verification**:

* Command/check: `jq '.scripts | with_entries(select(.key | test("^(demo|build|pages|schedule|aggregate|dream|test|typecheck|lint)")))' package.json`
  * Result: PASS - script names and command bodies are separated.
  * Evidence: `demo:snapshot` runs `scripts/demo/export-pages-snapshot.ts`; `demo:build:pages` runs `vite build --mode demo-pages` and `scripts/demo/assemble-pages-dist.ts`; `demo:scan:pages` runs `scripts/demo/scan-pages-demo.ts`.
* Command/check: `rg -n 'demo:snapshot|demo:build:pages|demo:scan:pages|scheduler|aggregate|dream' package.json scripts/demo scripts/lib/pages-demo-build.ts`
  * Result: PASS - package script wiring keeps fixture authoring separate from Pages build and scan commands.
  * Evidence: Matches show `demo:build:pages` has no `demo:snapshot`, scheduler, aggregate, or Dream runtime invocation.
* Command/check: `sed -n '1,220p' scripts/lib/pages-demo-build.ts`
  * Result: PASS - build library requires committed public fixture inputs.
  * Evidence: Required public files include `demo/live-data.snapshot.json`, `demo/snapshot-metadata.json`, and `demo/graphs/index.json`.
* UI product-surface check: N/A - script wiring inspection only; no user-facing surface changed.
* UI craft check: N/A - script wiring inspection only; no UI changed.

**BQC Fixes**:

* N/A - verification-only task; no application code changed.

### Task T004 - Record selected local input counts for Trend Finder, Engine Replay, advanced artifacts, and Dream

**Started**: 2026-06-25 04:11 **Completed**: 2026-06-25 04:12 **Duration**: 1 minute

**Notes**:

* Inspected `src/data/live-data.json` with structured `jq` queries that printed keys, states, and aggregate counts only.
* Resolved Trend Finder data path to `.extensions.items["trend-finder"].data`.
* Recorded selected input counts for Trend Finder topics, evidence, sources, watchlist rows, prediction/retro/story-log data, advanced artifact categories, sanitized Engine Replay state, and Dream prescription fields.

**Files Changed**:

* `.spec_system/specs/phase33-session02-freeze-public-fixtures/implementation-notes.md` - recorded selected local input count summary and T004 evidence.

**Verification**:

* Command/check: `test -s src/data/live-data.json && jq 'keys' src/data/live-data.json`
  * Result: PASS - local selected input exists and parses as JSON.
  * Evidence: Top-level keys include `extensions`, `dream`, `generatedAt`, and other host data branches.
* Command/check: `jq '{extensionsType: (.extensions | type), extensionKeys: (if (.extensions | type) == "object" then (.extensions | keys) else [] end), extensionLength: (if (.extensions | type) == "array" then (.extensions | length) else null end)}' src/data/live-data.json`

### Task T005 - Record current committed public snapshot counts and existing gaps

**Started**: 2026-06-25 04:12 **Completed**: 2026-06-25 04:13 **Duration**: 1 minute

**Notes**:

* Inspected the current committed public fixture before exporter changes or fixture writes.
* Recorded pre-freeze gaps: public snapshot has fewer Trend Finder topics/evidence rows than the selected input, no exported Engine Replay state, no advanced movement/industry/run-narrative artifacts, and `dream: null`.
* Kept the inspection count-only and did not copy evidence snippets or Dream bodies.

**Files Changed**:

* `.spec_system/specs/phase33-session02-freeze-public-fixtures/implementation-notes.md` - recorded current public snapshot count summary and T005 evidence.

**Verification**:

* Command/check: `test -s demo-website/public/demo/live-data.snapshot.json && jq 'keys' demo-website/public/demo/live-data.snapshot.json`
  * Result: PASS - committed public snapshot exists and parses as JSON.
  * Evidence: Top-level keys include `extensions`, `dream`, `generatedAt`, and other host branches.
* Command/check: `jq '{extensionsType: (.extensions | type), extensionKeys: (if (.extensions | type) == "object" then (.extensions | keys) else [] end), trendItemExists: (.extensions.items["trend-finder"] != null), dreamType: (.dream | type)}' demo-website/public/demo/live-data.snapshot.json`
  * Result: PASS - public snapshot has a Trend Finder extension item and `dream` is currently null.
  * Evidence: `trendItemExists` was true; `dreamType` was `null`.
* Command/check: `jq '(.extensions.items["trend-finder"].data // {}) as $tf | (.dream // {}) as $dream | {generatedAt: .generatedAt, trendStatus: (.extensions.items["trend-finder"].status // null), dataState: ($tf.provenance.dataState // null), analysisState: ($tf.provenance.analysisState // null), sourceState: ($tf.provenance.sourceState // null), topics: (($tf.topics // []) | length), evidence: (($tf.evidence // []) | length), sources: (($tf.sources // []) | length), watchlist: (($tf.watchlist // []) | length), predictions: (($tf.predictionRetroSummary.predictions // []) | length), retros: (($tf.predictionRetroSummary.retrospectives // []) | length), storyLog: (($tf.predictionRetroSummary.storyLog // []) | length), demandClusters: (($tf.demandClusters // []) | length), industryEvents: (($tf.industryEvents // []) | length), runNarratives: (($tf.runNarratives // []) | length), movementAnalyses: (($tf.movementAnalyses // []) | length), engineTraceState: ($tf.engineTrace.state // null), engineTraceDecisions: (($tf.engineTrace.decisionTimeline // []) | length), engineTraceSources: (($tf.engineTrace.sources // []) | length), engineTraceArtifacts: (($tf.engineTrace.artifacts // []) | length), engineTraceSections: (($tf.engineTrace.sections // []) | length), engineTraceNarrations: (($tf.engineTrace.stageNarrations // []) | length), engineTraceTopics: (($tf.engineTrace.topics // []) | length), engineTraceWatchlist: (($tf.engineTrace.watchlist // []) | length), dreamIsNull: (.dream == null), dreamPrescriptions: (($dream.prescriptions // []) | length), dreamEvidenceLines: ([$dream.prescriptions[]? | (.evidence // [])[]?] | length), dreamImpactFields: ([$dream.prescriptions[]? | .impact? | select(. != null)] | length), dreamTags: ([$dream.prescriptions[]? | (.tags // [])[]?] | length), dreamGeneratedAtPresent: ($dream.generatedAt != null)}' demo-website/public/demo/live-data.snapshot.json`
  * Result: PASS - current public snapshot counts were recorded.
  * Evidence: Counts are 8 topics, 16 evidence rows, 12 sources, 3 watchlist rows, 8 predictions, 10 retrospectives, 12 story-log rows, no Engine Replay state/artifacts, and no Dream prescriptions because `dream` is null.
* UI product-surface check: N/A - count-only fixture inspection; no user-facing surface changed.
* UI craft check: N/A - count-only fixture inspection; no UI changed.

**BQC Fixes**:

* N/A - count-only inspection task; no application code changed.

### Task T006 - Add minimal manifest count summary and Dream field policy metadata

**Started**: 2026-06-25 04:13 **Completed**: 2026-06-25 04:15 **Duration**: 2 minutes

**Notes**:

* Added typed public snapshot count-summary metadata for Trend Finder and Dream Review.
* Count summaries are derived from the public-safe projected output after allowlist projection and before metadata/manifest writing.
* Added Dream Review field-policy metadata with explicit `not-exported` state for the current exporter behavior and Session 04 as the allowlist handoff.
* Preserved the existing single manifest and metadata path; no separate Trend Finder-only or Dream-only manifest was introduced.

**Files Changed**:

* `scripts/lib/pages-demo-snapshot.ts` - added count-summary and Dream field-policy types, guarded count helpers, metadata wiring, and Dream policy construction.
* `.spec_system/specs/phase33-session02-freeze-public-fixtures/implementation-notes.md` - recorded metadata design evidence.

**Verification**:

* Command/check: `bun run typecheck:scripts`
  * Result: PASS - script TypeScript typecheck completed with exit code 0.
  * Evidence: `tsc --noEmit -p tsconfig.scripts.json` passed after exporter metadata changes.
* Command/check: targeted code inspection of `scripts/lib/pages-demo-snapshot.ts`
  * Result: PASS - metadata now includes `countSummary` and `dreamFieldPolicy`, and `runPagesDemoSnapshot` passes projected `liveData` into `buildMetadata`.
  * Evidence: `PublicDemoSnapshotMetadata` includes the new fields; `buildSnapshotCountSummary` reads sanitized output via guarded record/array helpers; `buildDreamFieldPolicy` records `not-exported` until Dream is allowlisted.
* UI product-surface check: N/A - exporter metadata only; no route or component changed.
* UI craft check: N/A - exporter metadata only; no UI changed.

**BQC Fixes**:

* Trust boundary enforcement: Count summary uses projected public-safe LiveData after validation/projection rather than raw input (`scripts/lib/pages-demo-snapshot.ts`).
* Contract alignment: Metadata and manifest types now include the generated count summary and Dream field policy (`scripts/lib/pages-demo-snapshot.ts`).

***

### Task T007 - Update focused snapshot exporter tests for deterministic metadata

**Started**: 2026-06-25 04:15 **Completed**: 2026-06-25 04:16 **Duration**: 1 minute

**Notes**:

* Extended the focused dry-run manifest test to assert deterministic `countSummary` values for Trend Finder and Dream Review.
* Added assertions that metadata and manifest carry the same `countSummary` and `dreamFieldPolicy` values.
* Extended the write test to assert persisted manifest JSON includes count summary and Dream field policy metadata.

**Files Changed**:

* `scripts/lib/__tests__/pages-demo-snapshot.test.ts` - added manifest/metadata assertions for count summary and Dream field policy.
* `.spec_system/specs/phase33-session02-freeze-public-fixtures/implementation-notes.md` - recorded T007 evidence.

**Verification**:

* Command/check: `bun run typecheck:scripts`
  * Result: PASS - script TypeScript typecheck completed with exit code 0 after test updates.
  * Evidence: `tsc --noEmit -p tsconfig.scripts.json` passed with the new test assertions.
* Command/check: targeted inspection of `scripts/lib/__tests__/pages-demo-snapshot.test.ts`
  * Result: PASS - tests now cover deterministic manifest metadata, count summary, Dream field policy, and persisted manifest fields.
  * Evidence: Dry-run test asserts `first.manifest.countSummary`, `first.manifest.dreamFieldPolicy`, and metadata parity; write test asserts persisted manifest `countSummary` and `dreamFieldPolicy`.
* UI product-surface check: N/A - script test only; no user-facing surface changed.
* UI craft check: N/A - script test only; no UI changed.

**BQC Fixes**:

* Contract alignment: Focused tests now verify the metadata/manifest contract for count summary and Dream field policy (`scripts/lib/__tests__/pages-demo-snapshot.test.ts`).

### Task T008 - Run focused snapshot exporter test file before fixture writes

**Started**: 2026-06-25 04:18 **Completed**: 2026-06-25 04:18 **Duration**: 1 minute

**Notes**:

* Ran the focused snapshot exporter test file after exporter/test updates and before any dry-run or final fixture write.
* All focused exporter tests passed.

**Files Changed**:

* `.spec_system/specs/phase33-session02-freeze-public-fixtures/implementation-notes.md` - recorded pre-write focused test result.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/pages-demo-snapshot.test.ts`
  * Result: PASS - focused snapshot exporter test file passed.
  * Evidence: Vitest reported 1 test file passed and 7 tests passed.
* UI product-surface check: N/A - script test only; no user-facing surface changed.
* UI craft check: N/A - script test only; no UI changed.

**BQC Fixes**:

### Task T010 - Compare dry-run projected counts against selected input counts

**Started**: 2026-06-25 04:19 **Completed**: 2026-06-25 04:21 **Duration**: 2 minutes

**Notes**:

* Ran the exporter in library dry-run mode to inspect only count-summary metadata, Dream policy metadata, scan status, and file-write status.
* Compared projected counts against the selected local input baseline and recorded expected pre-hardening gaps.
* Corrected the T004/T005 prediction and retrospective count notes to use both accepted aliases: `predictions`/`retrospectives` and `recentPredictions`/`recentRetros`.
* Confirmed no files were written during the projected-count inspection.

**Files Changed**:

* `.spec_system/specs/phase33-session02-freeze-public-fixtures/implementation-notes.md` - recorded dry-run projected counts, deltas, and alias correction.

**Verification**:

* Command/check: `bun -e 'import { runPagesDemoSnapshot } from "./scripts/lib/pages-demo-snapshot"; const result = await runPagesDemoSnapshot({ dryRun: true, capturedAt: "2026-06-25T01:18:58.994Z", sourceCommit: "95cd61a49ecd" }); console.log(JSON.stringify({ dryRun: result.dryRun, filesWritten: result.filesWritten, scan: result.manifest.scan, countSummary: result.manifest.countSummary, dreamFieldPolicy: result.manifest.dreamFieldPolicy }, null, 2));'`
  * Result: PASS - dry-run projected counts were printed without writing files.
  * Evidence: `dryRun` true, `filesWritten` empty, scan status `pass`, issue count 0, projected counts 8 topics, 16 evidence rows, 12 sources, 3 watchlist rows, 9 predictions, 10 retrospectives, 12 story-log rows, no Engine Replay state/artifacts, and Dream `not-exported`.
* Command/check: `jq '(.extensions.items["trend-finder"].data) as $tf | {predictions: ((($tf.predictionRetroSummary.predictions // $tf.predictionRetroSummary.recentPredictions // []) | length)), retrospectives: ((($tf.predictionRetroSummary.retrospectives // $tf.predictionRetroSummary.recentRetros // []) | length)), storyLog: (($tf.predictionRetroSummary.storyLog // []) | length)}' src/data/live-data.json`
  * Result: PASS - selected local input prediction/retro aliases were counted accurately.
  * Evidence: 9 predictions, 10 retrospectives, and 50 story-log rows.
* Command/check: `jq '(.extensions.items["trend-finder"].data // {}) as $tf | {predictions: ((($tf.predictionRetroSummary.predictions // $tf.predictionRetroSummary.recentPredictions // []) | length)), retrospectives: ((($tf.predictionRetroSummary.retrospectives // $tf.predictionRetroSummary.recentRetros // []) | length)), storyLog: (($tf.predictionRetroSummary.storyLog // []) | length)}' demo-website/public/demo/live-data.snapshot.json`
  * Result: PASS - current public snapshot prediction/retro aliases were counted accurately.
  * Evidence: 8 predictions, 10 retrospectives, and 12 story-log rows.
* UI product-surface check: N/A - dry-run count inspection only; no user-facing surface changed.
* UI craft check: N/A - dry-run count inspection only; no UI changed.

**BQC Fixes**:

* Contract alignment: Updated count evidence to recognize both prediction/retro field aliases already used by the data contract.

### Task T011 - Run final snapshot export through atomic write path

**Started**: 2026-06-25 04:21 **Completed**: 2026-06-25 04:22 **Duration**: 1 minute

**Notes**:

* Ran the final snapshot export only after focused tests, dry-run, scan, and projected-count review passed.
* Exporter completed successfully and reported 5 allowed fixture targets written.
* Working-tree inspection showed no unexpected public demo fixture paths. Graph fixtures were reported by the exporter write list, but they had no content diff after the write.

**Files Changed**:

* `demo-website/public/demo/live-data.snapshot.json` - generated public LiveData fixture updated by `demo:snapshot`.
* `demo-website/public/demo/snapshot-metadata.json` - generated snapshot metadata updated by `demo:snapshot`.
* `demo-website/snapshot-manifest.json` - generated review manifest updated by `demo:snapshot`.
* `.spec_system/specs/phase33-session02-freeze-public-fixtures/implementation-notes.md` - recorded final fixture write result.

**Verification**:

* Command/check: `bun run demo:snapshot`
  * Result: PASS - final snapshot export completed successfully.
  * Evidence: Output reported captured at `2026-06-25T01:21:06.085Z`, source commit `95cd61a49ecd`, scan `pass (0 issues)`, routes covered 24, and files written 5.
* Command/check: `git diff --name-only`
  * Result: PASS - content diffs are limited to expected session/source/fixture files.
  * Evidence: Diff names included `.spec_system/state.json`, `demo-website/public/demo/live-data.snapshot.json`, `demo-website/public/demo/snapshot-metadata.json`, `demo-website/snapshot-manifest.json`, `scripts/lib/__tests__/pages-demo-snapshot.test.ts`, and `scripts/lib/pages-demo-snapshot.ts`.
* Command/check: `find demo-website/public/demo -maxdepth 3 -type f | sort`
  * Result: PASS - public demo fixture file set remains bounded.
  * Evidence: Files under the public demo fixture directory are `graphs/ai-os.json`, `graphs/index.json`, `live-data.snapshot.json`, `snapshot-metadata.json`, and `trend-finder-assets/README.md`.
* UI product-surface check: N/A - fixture generation only; no route or component source changed.
* UI craft check: N/A - fixture generation only; no UI source changed.

**BQC Fixes**:

* Duplicate action prevention: Final fixture write used the exporter's atomic write plan with duplicate target validation (`scripts/lib/pages-demo-snapshot.ts`).
* Failure path completeness: Final write was gated by successful dry-run and privacy scan; exporter reports write failures through `PagesDemoSnapshotError`.

### Task T012 - Review generated LiveData fixture counts, labels, and caveats

**Started**: 2026-06-25 04:22 **Completed**: 2026-06-25 04:23 **Duration**: 1 minute

**Notes**:

* Reviewed generated `live-data.snapshot.json` with count-only and label-only queries.
* Confirmed Trend Finder is populated with 8 public fixture topics, 16 evidence rows, 12 sources, 3 watchlist rows, 9 predictions, 10 retrospectives, and 12 story-log rows.
* Confirmed provenance labels describe a public fixture and runtime is disabled for the hosted public snapshot.
* Confirmed Dream branch remains `null`; this is recorded as a Session 04 allowlist projection caveat.
* Structured topic inspection confirmed topic rows have schema-valid statuses and bounded evidence ID arrays; one topic has zero linked evidence IDs, which is retained as a Session 03 projection-coherence caveat.

**Files Changed**:

* `.spec_system/specs/phase33-session02-freeze-public-fixtures/implementation-notes.md` - recorded generated fixture counts and T012 evidence.

**Verification**:

* Command/check: `jq '(.extensions.items["trend-finder"].data // {}) as $tf | (.dream // {}) as $dream | {generatedAt: .generatedAt, isExample: .isExample, trendStatus: (.extensions.items["trend-finder"].status // null), dataState: ($tf.provenance.dataState // null), analysisState: ($tf.provenance.analysisState // null), sourceState: ($tf.provenance.sourceState // null), dataLabel: ($tf.provenance.dataLabel // null), analysisLabel: ($tf.provenance.analysisLabel // null), sourceLabel: ($tf.provenance.sourceLabel // null), runtimeProvider: ($tf.runtime.provider // null), runtimeStatus: ($tf.runtime.status // null), topics: (($tf.topics // []) | length), evidence: (($tf.evidence // []) | length), sources: (($tf.sources // []) | length), watchlist: (($tf.watchlist // []) | length), predictions: ((($tf.predictionRetroSummary.predictions // $tf.predictionRetroSummary.recentPredictions // []) | length)), retrospectives: ((($tf.predictionRetroSummary.retrospectives // $tf.predictionRetroSummary.recentRetros // []) | length)), storyLog: (($tf.predictionRetroSummary.storyLog // []) | length), demandClusters: (($tf.demandClusters // []) | length), industryEvents: (($tf.industryEvents // []) | length), runNarratives: (($tf.runNarratives // []) | length), movementAnalyses: (($tf.movementAnalyses // []) | length), engineTraceState: ($tf.engineTrace.state // null), engineTraceDecisions: (($tf.engineTrace.decisionTimeline // []) | length), engineTraceArtifacts: (($tf.engineTrace.artifacts // []) | length), dreamIsNull: (.dream == null), dreamPrescriptions: (($dream.prescriptions // []) | length), dreamTags: ([$dream.prescriptions[]? | (.tags // [])[]?] | length)}' demo-website/public/demo/live-data.snapshot.json`
  * Result: PASS - generated LiveData fixture parses and has populated Trend Finder data.
  * Evidence: Counts are 8 topics, 16 evidence rows, 12 sources, 3 watchlist rows, 9 predictions, 10 retrospectives, 12 story-log rows, runtime disabled, and Dream null.
* Command/check: `jq '{topLevelKeys: keys, trendDataKeys: (.extensions.items["trend-finder"].data | keys)}' demo-website/public/demo/live-data.snapshot.json`
  * Result: PASS - generated fixture shape remains centered on the existing LiveData contract.
  * Evidence: Top-level keys include `extensions`, `dream`, and host data branches; Trend Finder keys include `topics`, `evidence`, `sources`, `watchlist`, `predictionRetroSummary`, `provenance`, and `runtime`.
* Command/check: `jq '(.extensions.items["trend-finder"].data.topics // []) | map({id, status, evidenceCount, evidenceIds: (.evidenceIds | length)})' demo-website/public/demo/live-data.snapshot.json`
  * Result: PASS with caveat - topic rows are present with schema-valid statuses and bounded evidence ID arrays.
  * Evidence: 8 rows were returned; evidence ID array lengths are bounded at 12 or fewer, and one row has zero evidence IDs for Session 03 projection coherence review.
* UI product-surface check: N/A - fixture data review only; no route or component source changed.
* UI craft check: N/A - fixture data review only; no UI changed.

**BQC Fixes**:

* Contract alignment: Generated fixture shape was inspected against the existing LiveData/Trend Finder branch contract.

* Reviewed generated `snapshot-metadata.json` and `snapshot-manifest.json` for source commit, captured timestamp, route coverage, input source statuses, redaction counts, scan status, count summary, field policies, and write targets.
* Confirmed both metadata and manifest contain `countSummary` and `dreamFieldPolicy`.
* Confirmed manifest still contains the existing Trend Finder field policy and expected file list.
* Confirmed no additional committed metadata or manifest files were introduced under `demo-website` outside `dist`.

**Files Changed**:

* `.spec_system/specs/phase33-session02-freeze-public-fixtures/implementation-notes.md` - recorded metadata/manifest review evidence.

**Verification**:

* Command/check: `jq '{schemaVersion, capturedAt, sourceCommit, exporterVersion, routeCoverageCount: (.routeCoverage | length), inputSources: [.inputSources[] | {id, status, kind}], redactionCounts, scan, countSummary, dreamFieldPolicy}' demo-website/public/demo/snapshot-metadata.json`
  * Result: PASS - generated metadata includes provenance, route coverage, input source status, redaction counts, scan result, count summary, and Dream policy.
  * Evidence: Captured at `2026-06-25T01:21:06.085Z`; source commit `95cd61a49ecd`; route coverage count 24; scan pass with issue count 0; Dream policy state `not-exported`.

### Task T016 - Confirm Pages build assembly consumes committed fixtures only

**Started**: 2026-06-25 04:25 **Completed**: 2026-06-25 04:26 **Duration**: 1 minute

**Notes**:

* Confirmed `demo:build:pages` remains a Vite demo-pages build plus `assemble-pages-dist.ts`; it does not invoke fixture snapshot authoring.
* Confirmed the Pages build library requires committed public fixture files before assembly.
* Confirmed build/assemble files have no disallowed snapshot exporter, scheduler, aggregate, Dream runtime, upload, admin, mutation, or bridge invocation.

**Files Changed**:

* `.spec_system/specs/phase33-session02-freeze-public-fixtures/implementation-notes.md` - recorded static build-boundary evidence.

**Verification**:

* Command/check: `jq '{demoBuildPages: .scripts["demo:build:pages"], demoSnapshot: .scripts["demo:snapshot"], demoScanPages: .scripts["demo:scan:pages"], aggregate: .scripts.aggregate, schedulerTrendFinder: .scripts["scheduler:trend-finder:run"], schedulerDream: .scripts["scheduler:dream:run"]}' package.json`
  * Result: PASS - package scripts keep Pages build, snapshot authoring, scan, aggregate, and schedulers separate.
  * Evidence: `demo:build:pages` runs only Vite demo-pages build and `assemble-pages-dist.ts`; `demo:snapshot` is a separate `export-pages-snapshot.ts` command.
* Command/check: `rg -n 'REQUIRED_PUBLIC_FILES|REQUIRED_OUTPUT_FILES|demo/live-data.snapshot.json|demo/snapshot-metadata.json|graphs/index.json|verifyPagesDemoBuildInputs|assemblePagesDemoDist' scripts/lib/pages-demo-build.ts`
  * Result: PASS - build library requires committed fixture inputs and verifies expected output files.
  * Evidence: Required public files include `demo/live-data.snapshot.json`, `demo/snapshot-metadata.json`, and `demo/graphs/index.json`.
* Command/check: `rg -n 'demo:snapshot|export-pages-snapshot|scheduler|aggregate|dream|upload|admin|mutation|bridge' scripts/lib/pages-demo-build.ts scripts/demo/assemble-pages-dist.ts || true`
  * Result: PASS - disallowed runtime/build commands are absent from Pages build/assemble path.
  * Evidence: Command returned no matches.
* UI product-surface check: N/A - build-boundary source inspection only; no route or component source changed.
* UI craft check: N/A - build-boundary source inspection only; no UI changed.

**BQC Fixes**:

* Contract alignment: Build assembly remains aligned with the static fixture contract and requires committed public fixture files.

### Task T018 - Finalize implementation notes and handoff

**Started**: 2026-06-25 04:27 **Completed**: 2026-06-25 04:28 **Duration**: 1 minute

**Notes**:

* Finalized implementation notes with changed-file list, command outcomes, count deltas, projection caveats, blockers, and Session 03/04 handoff notes.
* Confirmed all implementation tasks are ready to be marked complete.

**Files Changed**:

* `.spec_system/specs/phase33-session02-freeze-public-fixtures/implementation-notes.md` - added final implementation summary and T018 evidence.

**Verification**:

* Command/check: `git status --short`
  * Result: PASS - working tree contains expected session, source, and fixture changes.
  * Evidence: Modified files include `.spec_system/state.json`, public fixture JSON files, snapshot source/test files, and the Session 02 spec artifact directory.
* Command/check: `git diff --stat`
  * Result: PASS - diff stats are consistent with exporter/test changes and regenerated fixture files.
  * Evidence: Tracked diff includes 6 files changed before untracked Session 02 artifacts are added; graph fixtures were rewritten with no content diff.
* Command/check: `rg -n '^- \\[[ x]\\] T' .spec_system/specs/phase33-session02-freeze-public-fixtures/tasks.md`
  * Result: PASS - task checklist shows T001 through T017 complete and T018 ready for final checkoff.
  * Evidence: 17 completed rows and 1 pending T018 row before final checklist update.
* UI product-surface check: N/A - final session documentation only; no route or component source changed.
* UI craft check: N/A - final session documentation only; no UI changed.

**BQC Fixes**:

* N/A - final documentation task; no application code changed.

### Task T009 - Run dry-run snapshot export against selected local input

**Started**: 2026-06-25 04:18 **Completed**: 2026-06-25 04:19 **Duration**: 1 minute

**Notes**:

* Ran `demo:snapshot` in dry-run JSON mode before final fixture writes.
* The selected local input was used and projected; the graph registry and `ai-os` graph were parsed; Trend Finder assets were not applicable.
* Dry-run wrote no files and the in-memory public fixture scan passed.
* Redaction count summary: 3 private fields removed, 9 local paths removed, 3 auth details removed, 11 arrays trimmed, 9 labels replaced, and 0 unsafe strings replaced.

**Files Changed**:

* `.spec_system/specs/phase33-session02-freeze-public-fixtures/implementation-notes.md` - recorded dry-run result.

**Verification**:

* Command/check: `bun run demo:snapshot --dry-run --json`
  * Result: PASS - dry-run completed successfully with no file writes.
  * Evidence: JSON output had `ok: true`, `dryRun: true`, `filesWritten: []`, `routeCoverageCount: 24`, input source `live-data` status `used`, scan status `pass`, and issue count 0.
* UI product-surface check: N/A - exporter dry-run only; no user-facing surface changed.
* UI craft check: N/A - exporter dry-run only; no UI changed.

**BQC Fixes**:

* Trust boundary enforcement: Dry-run validated and projected `src/data/live-data.json` before any write.
* Failure path completeness: Dry-run completed before the final write path, preserving the required write precondition.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase33-session02-freeze-public-fixtures/implementation-notes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
