### Task T001 - Verify phase evidence and Dream fixture gap

**Started**: 2026-06-25 05:51 **Completed**: 2026-06-25 05:52 **Duration**: 1 minute

**Notes**:

* Verified Phase 33 progress evidence shows Sessions 01 through 03 complete and Session 04 not started.
* Confirmed committed Pages snapshot still exports no public Dream branch.
* Confirmed spec-system state lists Phase 33 Sessions 01 through 03 as completed sessions.

**Files Changed**:

* `.spec_system/specs/phase33-session04-harden-dream-projection/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase33-session04-harden-dream-projection/tasks.md` - updated task progress.

**Verification**:

* Command/check: `rg -n 'Session 0[1-4]|Progress|Complete|Not Started|dream.*null|Dream Review' .spec_system/PRD/phase_33/PRD_phase_33.md .spec_system/PRD/phase_33/session_0*_*.md`
  * Result: PASS - phase PRD records Sessions 01 through 03 complete and Session 04 not started, and documents the `dream: null` gap.
  * Evidence: matched Phase 33 progress rows and current snapshot gap text in `.spec_system/PRD/phase_33/PRD_phase_33.md`.
* Command/check: `jq '{dreamType:(.dream|type), dreamIsNull:(.dream == null), generatedAt:.generatedAt}' demo-website/public/demo/live-data.snapshot.json`
  * Result: PASS - public fixture gap is present.
  * Evidence: reported `dreamType` as `null` and `dreamIsNull` as `true`.
* Command/check: `jq '.completed_sessions | map(select(test("phase33-session0[1-3]")))' .spec_system/state.json`
  * Result: PASS - spec state confirms prior phase sessions are complete.
  * Evidence: returned `phase33-session01-capture-local-demo-runs`, `phase33-session02-freeze-public-fixtures`, and `phase33-session03-harden-trend-finder-projection`.
* UI product-surface check: N/A - documentation and fixture inspection only; no user-facing surface changed.
* UI craft check: N/A - no UI changed.

### Task T002 - Inspect Dream contracts, validation, transforms, and exporter

**Started**: 2026-06-25 05:52 **Completed**: 2026-06-25 05:57 **Duration**: 5 minutes

**Notes**:

* Confirmed private `DreamOutput` includes `date`, `model`, `generatedAt`, bounded prescriptions, and optional runtime metadata.
* Confirmed private Dream validation already rejects privacy issues, but the public Pages snapshot still needs a narrower allowlist because `LiveData.dream` is intentionally loose.
* Confirmed `deriveDreamData()` consumes a small browser-facing shape with `generatedAt`, `prescriptions`, optional `evidence`, `command`, `dollarImpact`, and `timeImpactMins`.
* Confirmed `scripts/lib/pages-demo-snapshot.ts` already owns public privacy scanning, redaction counters, metadata, manifest, and static fixture writes; this is the correct boundary for the Dream projection.

**Files Changed**:

* `.spec_system/specs/phase33-session04-harden-dream-projection/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase33-session04-harden-dream-projection/tasks.md` - updated task progress.

**Verification**:

* Command/check: `sed -n '1,260p' scripts/lib/dream/contracts.ts`
  * Result: PASS - private Dream output contract inspected.
  * Evidence: found `MAX_DREAM_PRESCRIPTIONS`, required `DreamOutput.model`, and required prescription fields.
* Command/check: `sed -n '1,620p' scripts/lib/dream/output-validation.ts`
  * Result: PASS - private validation behavior inspected.
  * Evidence: found schema validation for top-level Dream fields and prescription limits.
* Command/check: `sed -n '1,260p' scripts/lib/dream/output-reader.ts && sed -n '1,260p' scripts/lib/dream/loader.ts`
  * Result: PASS - private file reader and loader inspected.
  * Evidence: reader returns only validated Dream outputs and loader skips invalid or empty output files.
* Command/check: `rg -n "dream|deriveDreamData|transformDream|Dream" src/lib/home-transforms.ts src/lib/transforms/dream.ts src/lib/live-data-types.ts`
  * Result: PASS - consumer and public LiveData shape inspected.
  * Evidence: `DreamEntry` is loose, `transformDream()` reads prescriptions/lastRun, and `deriveDreamData()` normalizes prescriptions into dashboard suggestions.
* Command/check: `sed -n '1,2555p' scripts/lib/pages-demo-snapshot.ts`
  * Result: PASS - exporter boundary inspected.
  * Evidence: current public projection sets `dream: null`; metadata functions already summarize and label Dream output when `data.dream` is non-null.
* UI product-surface check: N/A - source inspection only; no user-facing surface changed.
* UI craft check: N/A - no UI changed.
* BQC Fixes: N/A - no runtime code changed in this task; contract alignment risk identified for later tasks.

### Task T003 - Run baseline Dream count and field-key review

**Started**: 2026-06-25 05:57 **Completed**: 2026-06-25 05:59 **Duration**: 2 minutes

**Notes**:

* Reviewed only aggregate Dream counts and key names from local generated input.
* Confirmed local generated input has 4 Dream prescriptions with safe public candidate keys: `id`, `title`, `summary`, `rationale`, `nextAction`, `priority`, and `tags`.
* Confirmed optional `evidence`, `command`, `dollarImpact`, and `timeImpactMins` are absent in the current local candidate but still required by the session allowlist when safe.
* Confirmed the public fixture still has no exported Dream branch.

**Files Changed**:

* `.spec_system/specs/phase33-session04-harden-dream-projection/implementation-notes.md` - recorded task evidence without raw Dream bodies.
* `.spec_system/specs/phase33-session04-harden-dream-projection/tasks.md` - updated task progress.

**Verification**:

* Command/check: `jq '{dreamType:(.dream|type), generatedAtPresent:(.dream.generatedAt|type == "string"), datePresent:(.dream.date|type == "string"), modelPresent:(.dream.model|type == "string"), metadataPresent:(.dream.metadata|type == "object"), prescriptionCount:(.dream.prescriptions|length // 0), prescriptionKeys:((.dream.prescriptions // []) | map(keys) | unique), optionalFieldCounts:{rationale:((.dream.prescriptions // []) | map(has("rationale")) | map(select(.)) | length), nextAction:((.dream.prescriptions // []) | map(has("nextAction")) | map(select(.)) | length), priority:((.dream.prescriptions // []) | map(has("priority")) | map(select(.)) | length), tags:((.dream.prescriptions // []) | map(has("tags")) | map(select(.)) | length), evidence:((.dream.prescriptions // []) | map(has("evidence")) | map(select(.)) | length), command:((.dream.prescriptions // []) | map(has("command")) | map(select(.)) | length), dollarImpact:((.dream.prescriptions // []) | map(has("dollarImpact")) | map(select(.)) | length), timeImpactMins:((.dream.prescriptions // []) | map(has("timeImpactMins")) | map(select(.)) | length)}}' src/data/live-data.json`
  * Result: PASS - aggregate local Dream counts and field keys reviewed without printing prescription bodies.
  * Evidence: reported object Dream input, 4 prescriptions, generatedAt/date/model/metadata present, and no current evidence or impact fields.
* Command/check: `bun --eval 'import { readFileSync } from "node:fs"; import { collectPublicDemoPrivacyIssues } from "./scripts/lib/pages-demo-snapshot"; const dream = JSON.parse(readFileSync("src/data/live-data.json", "utf8")).dream; const issues = collectPublicDemoPrivacyIssues(dream, "$.dream"); console.log(JSON.stringify({ issueCount: issues.length, codes: [...new Set(issues.map((issue) => issue.code))].sort(), paths: issues.map((issue) => issue.path).sort() }, null, 2));'`
  * Result: PASS - aggregate public privacy scanner baseline has no Dream issues.
  * Evidence: reported `issueCount: 0`.
* Command/check: `bun --eval 'import { readFileSync } from "node:fs"; import { validateDreamOutput } from "./scripts/lib/dream/output-validation"; const dream = JSON.parse(readFileSync("src/data/live-data.json", "utf8")).dream; const result = validateDreamOutput(dream); console.log(JSON.stringify(result.ok ? { ok: true, prescriptionCount: result.value.prescriptions.length, metadataPresent: result.value.metadata !== undefined } : { ok: false, issueCount: result.issues.length, codes: result.issues.map((issue) => issue.code) }, null, 2));'`
  * Result: PASS - current local Dream branch validates against the private Dream contract.
  * Evidence: reported `ok: true`, `prescriptionCount: 4`, and metadata present.
* Command/check: `jq '{publicDreamType:(.dream|type), publicDreamIsNull:(.dream == null)}' demo-website/public/demo/live-data.snapshot.json`
  * Result: PASS - committed public fixture still has no Dream branch.
  * Evidence: reported `publicDreamType: null` and `publicDreamIsNull: true`.
* UI product-surface check: N/A - data inspection only; no user-facing surface changed.
* UI craft check: N/A - no UI changed.

### Task T004 - Add Dream projection constants and allowlist helpers

**Started**: 2026-06-25 05:59 **Completed**: 2026-06-25 05:59 **Duration**: <1 minute

**Notes**:

* Added Dream projection limits aligned with `MAX_DREAM_PRESCRIPTIONS`.
* Added top-level and per-prescription allowlist sets for public Dream projection.
* Added dropped-field accounting so ignored private Dream fields still update redaction counters and privacy issue counts.

**Files Changed**:

* `scripts/lib/pages-demo-snapshot.ts` - added Dream projection constants, allowlist sets, and dropped-field accounting helper.
* `.spec_system/specs/phase33-session04-harden-dream-projection/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase33-session04-harden-dream-projection/tasks.md` - updated task progress.

**Verification**:

* Command/check: `bun --eval 'await import("./scripts/lib/pages-demo-snapshot.ts"); console.log("module ok")'`
  * Result: PASS - exporter module imports after the constants/helper change.
  * Evidence: command printed `module ok`.
* Command/check: targeted inspection of `scripts/lib/pages-demo-snapshot.ts`
  * Result: PASS - constants and allowlist helper are scoped to Dream projection and placed before the Trend Finder projection constants.
  * Evidence: `DREAM_TOP_LEVEL_ALLOWLIST`, `DREAM_PRESCRIPTION_ALLOWLIST`, and `countDroppedDreamFields()` are present.
* UI product-surface check: N/A - exporter helper only; no user-facing surface changed.
* UI craft check: N/A - no UI changed.
* BQC Fixes: N/A - helper preserves trust-boundary accounting but does not yet process runtime input.

***

### Task T005 - Implement safe Dream field projectors

**Started**: 2026-06-25 05:59 **Completed**: 2026-06-25 05:59 **Duration**: <1 minute

**Notes**:

* Added safe text projection that drops strings with public-demo privacy issues and counts each issue.
* Added bounded tag and evidence array projectors.
* Added command and impact number helpers that preserve only safe, finite public values.
* Added priority validation for the public `low`, `medium`, and `high` enum.

**Files Changed**:

* `scripts/lib/pages-demo-snapshot.ts` - added safe Dream string, id, array, priority, command, evidence, tag, and impact helper functions.
* `.spec_system/specs/phase33-session04-harden-dream-projection/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase33-session04-harden-dream-projection/tasks.md` - updated task progress.

**Verification**:

* Command/check: `bun --eval 'await import("./scripts/lib/pages-demo-snapshot.ts"); console.log("module ok")'`
  * Result: PASS - exporter module imports after adding field projectors.
  * Evidence: command printed `module ok`.
* Command/check: targeted inspection of `scripts/lib/pages-demo-snapshot.ts`
  * Result: PASS - field projectors use `collectPublicDemoPrivacyIssues()` and bounded arrays before any Dream data is exported.
  * Evidence: `safeDreamText()`, `projectDreamTags()`, `projectDreamEvidence()`, `projectDreamCommand()`, and `safeDreamImpactNumber()` are present.
* UI product-surface check: N/A - exporter helper only; no user-facing surface changed.
* UI craft check: N/A - no UI changed.
* BQC Fixes:
  * Trust boundary enforcement: unsafe Dream strings are dropped at field projection time instead of being passed to the public fixture (`scripts/lib/pages-demo-snapshot.ts`).

***

### Task T006 - Implement bounded prescription projector

**Started**: 2026-06-25 05:59 **Completed**: 2026-06-25 05:59 **Duration**: <1 minute

**Notes**:

* Added a Dream prescription projector that requires safe `id`, `title`, and `summary`.
* Preserved optional allowlisted `rationale`, `nextAction`, `priority`, `tags`, `evidence`, `command`, `dollarImpact`, and `timeImpactMins` only when safe.
* Added per-prescription dropped-field accounting for private or out-of-allowlist keys.

**Files Changed**:

* `scripts/lib/pages-demo-snapshot.ts` - added `projectDreamPrescription()`.
* `.spec_system/specs/phase33-session04-harden-dream-projection/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase33-session04-harden-dream-projection/tasks.md` - updated task progress.

**Verification**:

* Command/check: `bun --eval 'await import("./scripts/lib/pages-demo-snapshot.ts"); console.log("module ok")'`
  * Result: PASS - exporter module imports after adding the prescription projector.
  * Evidence: command printed `module ok`.
* Command/check: targeted inspection of `scripts/lib/pages-demo-snapshot.ts`
  * Result: PASS - projector requires schema-minimum public fields and bounds optional public fields.
  * Evidence: `projectDreamPrescription()` returns `null` when required safe fields are absent and never spreads raw prescription records into the public output.
* UI product-surface check: N/A - exporter projection only; no user-facing surface changed.
* UI craft check: N/A - no UI changed.
* BQC Fixes:
  * Trust boundary enforcement: raw prescription records are not copied wholesale; every exported field is allowlisted and validated (`scripts/lib/pages-demo-snapshot.ts`).
  * Failure path completeness: invalid prescriptions become omitted rows, allowing the top-level projector to fall back to `dream: null` if none survive (`scripts/lib/pages-demo-snapshot.ts`).

***

### Task T007 - Implement top-level Dream projector

**Started**: 2026-06-25 05:59 **Completed**: 2026-06-25 05:59 **Duration**: <1 minute

**Notes**:

* Added `projectDreamData()` to preserve safe `generatedAt`, optional `date`, optional `lastRun`, and bounded prescriptions.
* Dropped model, metadata, provider/runtime state, and any other non-allowlisted top-level Dream fields.
* Added a final privacy scan over the projected Dream branch with unavailable fallback if a scanner issue remains.

**Files Changed**:

* `scripts/lib/pages-demo-snapshot.ts` - added top-level Dream projection.
* `.spec_system/specs/phase33-session04-harden-dream-projection/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase33-session04-harden-dream-projection/tasks.md` - updated task progress.

**Verification**:

* Command/check: `bun --eval 'await import("./scripts/lib/pages-demo-snapshot.ts"); console.log("module ok")'`
  * Result: PASS - exporter module imports after adding the top-level Dream projector.
  * Evidence: command printed `module ok`.
* Command/check: targeted inspection of `scripts/lib/pages-demo-snapshot.ts`
  * Result: PASS - top-level projector does not export `model`, `metadata`, provider labels, or runtime details.
  * Evidence: `projectDreamData()` constructs a fresh `DreamEntry` from allowlisted fields and returns `null` if generatedAt or all prescriptions are unavailable.
* UI product-surface check: N/A - fixture projection only; no user-facing surface changed.
* UI craft check: N/A - no UI changed.
* BQC Fixes:
  * Trust boundary enforcement: Dream branch is re-created from allowlisted fields and privacy-scanned before returning (`scripts/lib/pages-demo-snapshot.ts`).
  * Failure path completeness: missing, empty, or fully unsafe Dream input falls back to `null` instead of partially exporting private data (`scripts/lib/pages-demo-snapshot.ts`).

### Task T008 - Add transform compatibility assertions

**Started**: 2026-06-25 05:59 **Completed**: 2026-06-25 05:59 **Duration**: <1 minute

**Notes**:

* Added a focused Dream fixture to the snapshot exporter tests.
* Added assertions that projected Dream data passes through `deriveDreamData()` into dashboard suggestions with evidence, command, and impact fields.
* Verified private `model` and `metadata` fields are absent from the public projected Dream branch.

**Files Changed**:

* `scripts/lib/__tests__/pages-demo-snapshot.test.ts` - added Dream fixture and home-transform compatibility test.
* `.spec_system/specs/phase33-session04-harden-dream-projection/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase33-session04-harden-dream-projection/tasks.md` - updated task progress.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/pages-demo-snapshot.test.ts`
  * Result: PASS - focused snapshot exporter tests passed.
  * Evidence: 1 test file passed, 12 tests passed.
* Command/check: targeted inspection of `scripts/lib/__tests__/pages-demo-snapshot.test.ts`
  * Result: PASS - compatibility assertion exercises `deriveDreamData(data)` against projected public Dream data.
  * Evidence: test checks generated timestamp, two suggestions, evidence, command, dollar impact, and time impact.
* UI product-surface check: N/A - test-only change; no user-facing surface changed.
* UI craft check: N/A - no UI changed.
* BQC Fixes:
  * Contract alignment: test now verifies the exporter output matches the existing home dashboard Dream transform contract (`scripts/lib/__tests__/pages-demo-snapshot.test.ts`).

***

### Task T009 - Wire Dream projector into public LiveData projection

**Started**: 2026-06-25 05:59 **Completed**: 2026-06-25 05:59 **Duration**: <1 minute

**Notes**:

* Replaced the hard-coded public `dream: null` assignment with `projectDreamData(input.dream, counts)`.
* Verified the current local generated input now projects to a non-null Dream branch with 4 prescriptions.
* Verified projected local input still passes the public demo privacy scanner.

**Files Changed**:

* `scripts/lib/pages-demo-snapshot.ts` - wired Dream projection into `projectLiveDataForPublicDemo()`.
* `.spec_system/specs/phase33-session04-harden-dream-projection/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase33-session04-harden-dream-projection/tasks.md` - updated task progress.

**Verification**:

* Command/check: `bun --eval 'import { readFileSync } from "node:fs"; import { validateLiveData } from "./src/lib/validate-live-data"; import { projectLiveDataForPublicDemo, scanPublicDemoPayload } from "./scripts/lib/pages-demo-snapshot"; const input = validateLiveData(JSON.parse(readFileSync("src/data/live-data.json", "utf8"))); const { data } = projectLiveDataForPublicDemo(input, "2026-06-25T00:00:00.000Z"); const dream = data.dream; console.log(JSON.stringify({ dreamType: dream === null ? "null" : typeof dream, prescriptionCount: Array.isArray(dream?.prescriptions) ? dream.prescriptions.length : 0, scanStatus: scanPublicDemoPayload(data).status }, null, 2));'`
  * Result: PASS - current local Dream input projects into public LiveData.
  * Evidence: reported `dreamType: object`, `prescriptionCount: 4`, and `scanStatus: pass`.
* Command/check: `bun run test -- scripts/lib/__tests__/pages-demo-snapshot.test.ts`
  * Result: PASS - focused snapshot exporter tests pass with Dream projection wired.
  * Evidence: 1 test file passed, 12 tests passed.
* UI product-surface check: N/A - fixture data path only; no user-facing surface changed.
* UI craft check: N/A - no UI changed.
* BQC Fixes:
  * Failure path completeness: public projection now returns `dream: null` for missing, empty, or fully unsafe Dream input while exporting safe populated input (`scripts/lib/pages-demo-snapshot.ts`).

***

### Task T010 - Update Dream snapshot count summaries

**Started**: 2026-06-25 05:59 **Completed**: 2026-06-25 05:59 **Duration**: <1 minute

**Notes**:

* Updated Dream impact counting to count `dollarImpact` and `timeImpactMins` fields.
* Verified the current local generated input reports exported Dream counts after dry-run projection.
* An initial ad hoc fixture check failed because `DEFAULT_LIVE_DATA` did not include a Trend Finder item required by the exporter; reran verification against the real current input.

**Files Changed**:

* `scripts/lib/pages-demo-snapshot.ts` - added multi-key present-field counting and updated Dream impact summary fields.
* `.spec_system/specs/phase33-session04-harden-dream-projection/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase33-session04-harden-dream-projection/tasks.md` - updated task progress.

**Verification**:

* Command/check: `bun --eval 'import { runPagesDemoSnapshot } from "./scripts/lib/pages-demo-snapshot"; const result = await runPagesDemoSnapshot({ workspaceRoot: process.cwd(), capturedAt: "2026-06-25T00:00:00.000Z", dryRun: true }); console.log(JSON.stringify(result.manifest.countSummary.dream, null, 2));'`
  * Result: PASS - Dream count summary derives from the projected branch.
  * Evidence: reported `state: exported`, `prescriptions: 4`, `tags: 12`, `evidenceLines: 0`, `impactFields: 0`, and `generatedAtPresent: true`.
* Command/check: targeted inspection of `scripts/lib/pages-demo-snapshot.ts`
  * Result: PASS - impact counts use `dollarImpact` and `timeImpactMins`.
  * Evidence: `countPresentFieldsForKeys()` feeds `countSummary.dream.impactFields`.
* UI product-surface check: N/A - metadata/count logic only; no user-facing surface changed.
* UI craft check: N/A - no UI changed.
* BQC Fixes:
  * Contract alignment: count summary now matches the actual exported Dream impact field names (`scripts/lib/pages-demo-snapshot.ts`).

***

### Task T011 - Update Dream field policy metadata

**Started**: 2026-06-25 06:00 **Completed**: 2026-06-25 06:02 **Duration**: 2 minutes

**Notes**:

* Updated exported Dream policy to list generated timestamp, date or last-run label, prescription ids, titles, summaries, rationales, next actions, priority labels, tags, evidence lines, commands, and impact estimates.
* Updated exclusions to explicitly name model names, provider labels, raw prompts, raw logs, runtime details, diagnostics, local paths, credentials, and token-like strings.
* Replaced deferred policy wording with `deferredTo: none` now that Session 04 owns the projection.
* Updated stale tests that still expected deferred Session 04 policy for unavailable Dream fixtures.

**Files Changed**:

* `scripts/lib/pages-demo-snapshot.ts` - updated Dream field policy metadata.
* `scripts/lib/__tests__/pages-demo-snapshot.test.ts` - updated field-policy expectations for unavailable Dream fixtures.
* `.spec_system/specs/phase33-session04-harden-dream-projection/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase33-session04-harden-dream-projection/tasks.md` - updated task progress.

**Verification**:

* Command/check: `bun --eval 'import { runPagesDemoSnapshot } from "./scripts/lib/pages-demo-snapshot"; const result = await runPagesDemoSnapshot({ workspaceRoot: process.cwd(), capturedAt: "2026-06-25T00:00:00.000Z", dryRun: true }); console.log(JSON.stringify(result.manifest.dreamFieldPolicy, null, 2));'`
  * Result: PASS - dry-run manifest reports Dream as allowlisted for the current local input.
  * Evidence: output included `state: allowlisted`, detailed included/excluded field lists, `fallbackLabels` with `Frozen real Dream Review snapshot`, and `deferredTo: none`.
* Command/check: `bun run test -- scripts/lib/__tests__/pages-demo-snapshot.test.ts`
  * Result: PASS - focused snapshot exporter tests pass after policy update.
  * Evidence: 1 test file passed, 12 tests passed.
* UI product-surface check: N/A - metadata/test change only; no user-facing surface changed.
* UI craft check: N/A - no UI changed.
* BQC Fixes:
  * Contract alignment: manifest and metadata policy now describe the fields actually exported by the Dream projector (`scripts/lib/pages-demo-snapshot.ts`).

### Task T013 - Record Dream count deltas and projection decisions

**Started**: 2026-06-25 06:03 **Completed**: 2026-06-25 06:03 **Duration**: <1 minute

**Notes**:

* Count delta from pre-session public fixture to regenerated fixture:
  * Dream state: `not-exported` -> `exported`.
  * Prescriptions: `0` -> `4`.
  * Tags: `0` -> `12`.
  * Evidence lines: `0` -> `0` because current local candidate has no evidence field.
  * Impact fields: `0` -> `0` because current local candidate has no `dollarImpact` or `timeImpactMins` fields.
  * Generated timestamp present: `false` -> `true`.
* Projection decisions:
  * Preserve only allowlisted Dream fields needed by public demo and home dashboard transforms.
  * Drop private top-level `model`, `metadata`, provider labels, runtime details, diagnostics, raw prompts/logs, local paths, credentials, and token-like strings.
  * Preserve optional `evidence`, `command`, `dollarImpact`, and `timeImpactMins` only when present and safe; current local fixture does not include those optional fields.
  * Keep public demo static-only; do not run Dream Review, schedulers, collectors, bridge endpoints, uploads, analytics, or writes during Pages generation.

**Files Changed**:

* `.spec_system/specs/phase33-session04-harden-dream-projection/implementation-notes.md` - added explicit Dream count delta and decision summary.
* `.spec_system/specs/phase33-session04-harden-dream-projection/tasks.md` - updated task progress.

**Verification**:

* Command/check: `jq '{dreamType:(.dream|type), generatedAtPresent:(.dream.generatedAt|type == "string"), datePresent:(.dream.date|type == "string"), lastRunPresent:(.dream.lastRun|type == "string"), prescriptionCount:(.dream.prescriptions|length // 0), prescriptionKeys:((.dream.prescriptions // []) | map(keys) | unique)}' demo-website/public/demo/live-data.snapshot.json`
  * Result: PASS - regenerated Dream payload summary recorded without raw Dream bodies.
  * Evidence: reported object Dream branch, generatedAt/date present, 4 prescriptions, and public candidate keys only.
* Command/check: `jq '.countSummary.dream' demo-website/public/demo/snapshot-metadata.json`
  * Result: PASS - count deltas align with regenerated metadata.
  * Evidence: reported exported state, 4 prescriptions, 12 tags, 0 evidence lines, 0 impact fields, and generatedAt present.
* Command/check: `jq '.dreamFieldPolicy' demo-website/snapshot-manifest.json`
  * Result: PASS - projection decisions align with regenerated manifest policy.
  * Evidence: manifest reports allowlisted inclusions and private exclusions with `deferredTo: none`.
* UI product-surface check: N/A - implementation notes only; no user-facing surface changed.
* UI craft check: N/A - no UI changed.

* UI product-surface check: N/A - test-only change; no user-facing surface changed.
* UI craft check: N/A - no UI changed.
* BQC Fixes:
  * Contract alignment: positive test locks the public Dream allowlist to fields described by the session spec (`scripts/lib/__tests__/pages-demo-snapshot.test.ts`).

* UI product-surface check: N/A - test-only change; no user-facing surface changed.
* UI craft check: N/A - no UI changed.
* BQC Fixes:
  * Error information boundaries: tests prove private runtime/provider details and token-like strings do not leave the projection boundary (`scripts/lib/__tests__/pages-demo-snapshot.test.ts`).

**Started**: 2026-06-25 06:05 **Completed**: 2026-06-25 06:06 **Duration**: 1 minute

**Notes**:

* Added fallback coverage for missing Dream input, empty prescriptions, and fully unsafe prescription content.
* Verified each fallback keeps `dream: null`, produces no dashboard suggestions, and passes the public privacy scanner.

* UI product-surface check: N/A - test-only change; no user-facing surface changed.
* UI craft check: N/A - no UI changed.
* BQC Fixes:
  * Failure path completeness: tests lock the unavailable fallback for invalid Dream input instead of partial export (`scripts/lib/__tests__/pages-demo-snapshot.test.ts`).

## Design Decisions

### Decision 1: Project Dream Through An Explicit Public Allowlist

**Context**: Private Dream output includes model/provider/runtime metadata and can contain extra fields on prescriptions.

**Options Considered**:

1. Reuse private Dream output as-is after validation - rejected because the private contract includes fields the public demo must not expose.
2. Build a fresh public Dream object from explicit fields - chosen.

**Chosen**: Build a fresh public Dream object from explicit fields.

**Rationale**: This keeps the public snapshot small, deterministic, browser-safe, and aligned with the home dashboard transform contract.

### Decision 2: Drop Unsafe Optional Fields And Fall Back When Required Fields Are Unsafe

**Context**: Optional Dream fields can contain local paths, prompt text, command output, credentials, or token-like strings.

**Options Considered**:

1. Replace unsafe optional fields with generic fallback text - rejected because it would inflate public output with vague copy.
2. Drop unsafe optional fields and skip prescriptions whose required fields are unsafe - chosen.

**Chosen**: Drop unsafe optional fields and return `dream: null` if no safe prescriptions remain.

**Rationale**: This avoids leaks while keeping unavailable states honest and parseable.
