### Task T003 - Characterize current aggregate Dream output and live-data Dream shape

**Started**: 2026-06-29 19:34 **Completed**: 2026-06-29 19:36 **Duration**: 2 minutes

**Notes**:

* Current `scripts/lib/aggregate-orchestration.ts` calls `loadLatestDreamWithSource()`, assigns `dreamResult?.output ?? null`, and emits that value without health metadata.
* Current generated `src/data/live-data.json` has a Dream object dated `2026-06-28` with 4 prescriptions and metadata, but no `healthStatus` or `fixHint`.
* Current committed `src/data/live-data.example.json` has `dream: null`.
* Current loader result contract includes `output`, `source`, and `fileName`; an exploratory probe was corrected after assuming a non-existent `warnings` property.

**Files Changed**:

* `.spec_system/specs/phase38-session03-aggregate-and-dream-health/implementation-notes.md` - recorded baseline Dream output and writer behavior.

**Verification**:

* Command/check: `jq '.dream' src/data/live-data.json`
  * Result: PASS - Generated data has Dream output with `date`, `model`, `generatedAt`, `prescriptions`, and `metadata`, but no health metadata.
  * Evidence: Output showed `date: 2026-06-28` and 4 prescriptions.
* Command/check: `jq '.dream' src/data/live-data.example.json`
  * Result: PASS - Example fallback keeps `dream` as `null`.
  * Evidence: Output was `null`.
* Command/check: `sed -n '1148,1180p' scripts/lib/aggregate-orchestration.ts && sed -n '1488,1508p' scripts/lib/aggregate-orchestration.ts`
  * Result: PASS - Writer currently passes loaded Dream output through and attaches it to the root live-data object.
  * Evidence: Inspected `const dream = dreamResult?.output ?? null` and the final `dream` field assignment.
* Command/check: `bun -e "import { loadLatestDreamWithSource } from './scripts/lib/dream-loader.ts'; const result = await loadLatestDreamWithSource(); console.log(JSON.stringify(result ? { source: result.source, fileName: result.fileName, date: result.output.date, prescriptions: Array.isArray(result.output.prescriptions) ? result.output.prescriptions.length : null } : null, null, 2));"`
  * Result: PASS - Loader returned the primary AI OS Dream output `dream-2026-06-28.json` with 4 prescriptions.
  * Evidence: Command output was `{ source: "primary", fileName: "dream-2026-06-28.json", date: "2026-06-28", prescriptions: 4 }`.
* UI product-surface check: N/A - writer/data characterization only, no UI surface changed.
* UI craft check: N/A - writer/data characterization only, no UI surface changed.

**Notes**:

* Added `scripts/lib/dream/health.ts` with `evaluateDreamHealth()` for `healthy`, `never_ran`, `stale`, and `silent_failure`.
* Added bounded, scheduler-sanitized fix hints so lifecycle failure messages cannot leak private paths, raw streams, tokens, or emails.
* Added `attachDreamHealth()` so aggregate assembly can emit a minimal Dream object when no Dream output exists.
* Exported the helper from `scripts/lib/dream/index.ts`.

**Files Changed**:

* `scripts/lib/dream/health.ts` - new pure health mapper and Dream health field attachment helper.
* `scripts/lib/dream/index.ts` - exported the health mapper.
* `.spec_system/specs/phase38-session03-aggregate-and-dream-health/implementation-notes.md` - recorded task evidence.

**Verification**:

* Command/check: `bun -e "import { evaluateDreamHealth } from './scripts/lib/dream/health.ts'; console.log(JSON.stringify([evaluateDreamHealth({ now: () => new Date('2026-06-29T00:00:00.000Z') }).healthStatus, evaluateDreamHealth({ output: { date: '2026-06-29', model: 'x', generatedAt: '2026-06-29T00:00:00.000Z', prescriptions: [] }, now: () => new Date('2026-06-29T01:00:00.000Z') }).healthStatus]));"`
  * Result: PASS - Mapper imports and returns `never_ran` for no output and `healthy` for fresh output.
  * Evidence: Command output was `["never_ran","healthy"]`.

**Started**: 2026-06-29 19:42 **Completed**: 2026-06-29 19:43 **Duration**: 1 minute

**Notes**:

* Added `DreamHealthStatus` to the browser live-data contract.
* Added optional `healthStatus` and nullable optional `fixHint` to `DreamEntry`, preserving old Dream objects and `dream: null` fallback compatibility.

**Files Changed**:

* `src/lib/live-data-types.ts` - typed additive Dream health fields.
* `.spec_system/specs/phase38-session03-aggregate-and-dream-health/implementation-notes.md` - recorded task evidence.

**Notes**:

* Added `DREAM_HEALTH_STATUSES` and Dream-specific fix-hint validation in `src/lib/validate-live-data.ts`.
* Preserved old Dream objects by leaving health fields optional.
* Invalid `healthStatus` values are removed, and unsafe or overlong `fixHint` values are removed.
* `fixHint` accepts ASCII-safe redaction placeholders while rejecting raw emails, bearer/auth strings, and POSIX/Windows private home paths.

**Files Changed**:

* `src/lib/validate-live-data.ts` - validates additive Dream health fields.
* `.spec_system/specs/phase38-session03-aggregate-and-dream-health/implementation-notes.md` - recorded task evidence.

**Verification**:

* Command/check: `bun -e "import { validateLiveData } from './src/lib/validate-live-data.ts'; const legacy = validateLiveData({ dream: { prescriptions: [] } }); const health = validateLiveData({ dream: { healthStatus: 'stale', fixHint: 'Run Dream again.' } }); console.log(JSON.stringify({ legacy: legacy.dream, health: health.dream }));"`

### Task T007 - Extend sanitizer coverage for Windows usernames, full names, drive/home paths, emails, and configured names

**Started**: 2026-06-29 19:47 **Completed**: 2026-06-29 19:53 **Duration**: 6 minutes

**Notes**:

* Extended `REAL_USER` extraction to recognize Windows-style `Users` home paths after slash normalization.
* Added current-home redaction pairs for Windows drive paths and backslash variants.
* Added path-label redaction for drive-letter labels such as `C-Users-Alice-project`.
* Extended generic redaction to cover raw `C:\\Users\\...` and `C:/Users/...` paths.
* Preserved email redaction, configured `CLAUDE_OS_REDACT_NAMES`/`REDACT_NAMES`, and `CLAUDE_OS_ANONYMIZE=0` override behavior.

**Started**: 2026-06-29 19:53 **Completed**: 2026-06-29 19:57 **Duration**: 4 minutes

**Notes**:

* Added `normalizeAggregatePathLabel()` for browser-facing aggregate labels with forward slashes, collapsed duplicate slashes, trimmed trailing slashes, and uppercase Windows drive letters.
* Added `normalizeAggregatePathKey()` for deterministic comparison keys that collapse Windows slash direction and drive-letter casing.
* Reused the label normalizer in `getRedactedCodexHome()` so configured Codex home labels are stable before emission.

**Files Changed**:

* `scripts/lib/scan-helpers.ts` - added shared aggregate path normalization helpers.
* `.spec_system/specs/phase38-session03-aggregate-and-dream-health/implementation-notes.md` - recorded task evidence.

**Verification**:

* Command/check: `bun -e "import { normalizeAggregatePathLabel, normalizeAggregatePathKey, getRedactedCodexHome } from './scripts/lib/scan-helpers.ts'; console.log(JSON.stringify([normalizeAggregatePathLabel('c:\\\\Users\\\\Alice\\\\repo//'), normalizeAggregatePathKey('C:/Users/Alice/repo'), normalizeAggregatePathKey('c:\\\\Users\\\\Alice\\\\repo'), getRedactedCodexHome({ CODEX_HOME: '~/custom-codex' })]));"`
  * Result: PASS - Label and comparison helpers normalize Windows path variants consistently and preserve redacted configured Codex home labels.
  * Evidence: Output was `["C:/Users/Alice/repo","c:/users/alice/repo","c:/users/alice/repo","~/custom-codex"]`.
* BQC check: PASS - Contract alignment improved by centralizing path normalization for aggregate scanner owners.

### Task T009 - Add Windows-aware app and terminal detection

**Started**: 2026-06-29 19:57 **Completed**: 2026-06-29 20:05 **Duration**: 8 minutes

**Notes**:

* Added Windows Start Menu shortcut indexing and Program Files / `%LOCALAPPDATA%\\Programs` lookup behind the existing `findMacApp()` compatibility helper.
* Existing app-detection call sites now gain Windows desktop app detection without duplicating app-owner code in `detectApps()`.
* Added Windows Terminal, ConEmu/Cmder, and Terminus current-terminal inference.
* Added `windowsTerminal` to installed terminal detections and suppressed Apple Terminal probing outside macOS.
* Missing/unreadable Start Menu and program directories degrade to no detection through guarded `existsSync`/`readdirSync` checks.

**Files Changed**:

* `scripts/lib/scan-helpers.ts` - added Windows desktop app lookup helpers behind `findMacApp()`.
* `scripts/lib/app-detection.ts` - added terminal inference and Windows Terminal installed field.
* `.spec_system/specs/phase38-session03-aggregate-and-dream-health/implementation-notes.md` - recorded task evidence.

**Verification**:

* Command/check: `bun -e "import { detectApps } from './scripts/lib/app-detection.ts'; const apps = await detectApps(); console.log(JSON.stringify({ claudeApp: apps.claudeApp.detected, terminals: apps.terminals.current, hasWindowsTerminal: 'windowsTerminal' in apps.terminals.installed }));"`
  * Result: PASS - App detection runs without unavailable-location failures and includes the new `windowsTerminal` installed field.
  * Evidence: Output was `{"claudeApp":false,"terminals":{"detected":false,"name":"unknown"},"hasWindowsTerminal":true}`.
* Command/check: `WT_SESSION=abc bun -e "import { detectApps } from './scripts/lib/app-detection.ts'; const apps = await detectApps(); console.log(JSON.stringify(apps.terminals.current));"`
  * Result: PASS - Windows Terminal inference works from `WT_SESSION`.
  * Evidence: Output was `{"detected":true,"name":"Windows Terminal"}`.
* BQC check: PASS - Failure path completeness covered by guarded filesystem reads and fallback no-detection results.
* UI product-surface check: N/A - script detection code only, no UI surface changed.
* UI craft check: N/A - script detection code only, no UI surface changed.

### Task T010 - Ensure aggregate CLI detection uses shared Windows executable names and candidate directories

**Started**: 2026-06-29 20:05 **Completed**: 2026-06-29 20:08 **Duration**: 3 minutes

**Notes**:

* Verified `scripts/lib/tool-detection.ts` already delegates candidate directory construction to `candidateCliDirectories()` and Windows command expansion to `executableNames()` from `scripts/lib/platform.ts`.
* Verified `probeCliVersion()` has timeout and spawn-error failure paths and returns `undefined` for non-zero exits or missing output.
* No product-code change was required for this task because the existing implementation already matched the session requirement.

**Files Changed**:

* `.spec_system/specs/phase38-session03-aggregate-and-dream-health/implementation-notes.md` - recorded verification evidence.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/tool-detection.test.ts`
  * Result: PASS - 1 test file passed, 30 tests passed.
  * Evidence: Vitest output covered Windows PATHEXT expansion, POSIX-home fallback directories under win32 injection, PATH precedence, extra dirs, symlinks, non-executable files, non-zero exits, missing commands, and timeout behavior.
* BQC check: PASS - External dependency resilience covered by timeout handling and explicit undefined failure paths.
* UI product-surface check: N/A - CLI detection code only, no UI surface changed.
* UI craft check: N/A - CLI detection code only, no UI surface changed.

### Task T011 - Normalize session scanner workspace and project labels

**Started**: 2026-06-29 20:08 **Completed**: 2026-06-29 20:14 **Duration**: 6 minutes

**Notes**:

* Applied `normalizeAggregatePathLabel()` and `normalizeAggregatePathKey()` in `scripts/lib/session-scanner.ts`.
* Normalized project keys derived from JSONL paths so slash direction and Windows drive-label casing do not split one project into multiple aggregate buckets.
* Normalized generated-output map keys and daily session keys to avoid duplicate counts from slash variants.
* Kept display labels browser-facing while using deterministic keys for aggregation.

**Files Changed**:

* `scripts/lib/session-scanner.ts` - normalized project, activity-output, and daily-session path keys.
* `scripts/lib/scan-helpers.ts` - expanded aggregate path key normalization to drive-letter path labels.
* `.spec_system/specs/phase38-session03-aggregate-and-dream-health/implementation-notes.md` - recorded task evidence.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/session-scanner.test.ts`
  * Result: PASS - 1 test file passed, 41 tests passed.
  * Evidence: Existing session scanner behavior remained compatible after path-key normalization.

### Task T012 - Normalize skill scanner source paths and labels

**Started**: 2026-06-29 20:14 **Completed**: 2026-06-29 20:19 **Duration**: 5 minutes

**Notes**:

* Applied aggregate path normalization to installed skill root deduplication and discovered plugin skill root labels.
* Normalized raw JSONL lines before matching `SKILL.md` paths so Windows backslash paths are recognized.
* Normalized conversation-file keys used for per-conversation SKILL.md-read deduplication.
* Updated the existing skill scanner test mock to expose the new scan-helper normalization functions.

**Files Changed**:

* `scripts/lib/skill-scanner.ts` - normalized skill read paths, root dedupe keys, and discovered skill root labels.
* `scripts/lib/__tests__/skill-scanner.test.ts` - updated scan-helper mock for the new helper exports.
* `.spec_system/specs/phase38-session03-aggregate-and-dream-health/implementation-notes.md` - recorded task evidence.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/skill-scanner.test.ts`
  * Result: PASS after updating the stale scan-helper mock - 1 test file passed, 31 tests passed.
  * Evidence: Initial run failed because the test mock did not expose `normalizeAggregatePathLabel`/`normalizeAggregatePathKey`; after adding the mock exports, Vitest passed.
* BQC check: PASS - Contract alignment improved by using shared normalized labels and deterministic dedupe keys.
* UI product-surface check: N/A - script scanner code only, no UI surface changed.

### Task T013 - Add Windows Obsidian registry/config discovery with fallback behavior

**Started**: 2026-06-29 20:19 **Completed**: 2026-06-29 20:24 **Duration**: 5 minutes

**Notes**:

* Added guarded Obsidian `obsidian.json` registry/config reading via `appSupportDir("obsidian")`.
* Windows branch now trusts Obsidian config vault paths as overrides and scans `~/iCloudDrive`; macOS/Linux keep the existing Mobile Documents scan.
* Missing, malformed, or unreadable Obsidian config returns no candidates instead of failing aggregate.
* Memory folder parsing now normalizes absolute and relative paths before deriving workspace labels and decision markers.
* Updated the existing memory scanner test mock to expose new scan-helper exports.

**Files Changed**:

* `scripts/lib/memory-scanner.ts` - added Obsidian config discovery, Windows branch, and normalized memory relative paths.
* `scripts/lib/__tests__/memory-scanner.test.ts` - updated scan-helper mock for new helper exports.
* `.spec_system/specs/phase38-session03-aggregate-and-dream-health/implementation-notes.md` - recorded task evidence.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/memory-scanner.test.ts`
  * Result: PASS after updating the stale scan-helper mock - 1 test file passed, 26 tests passed.
  * Evidence: Initial run failed because the test mock did not expose `normalizeAggregatePathLabel`; after adding the mock export and Windows defaults, Vitest passed.
* BQC check: PASS - Failure path completeness covered by guarded config reads and degraded empty-candidate fallback.
* UI product-surface check: N/A - script scanner code only, no UI surface changed.
* UI craft check: N/A - script scanner code only, no UI surface changed.

### Task T014 - Attach Dream health metadata during aggregate assembly

**Started**: 2026-06-29 20:24 **Completed**: 2026-06-29 20:30 **Duration**: 6 minutes

**Notes**:

* Aggregate now loads Dream runtime state alongside latest Dream output.
* Aggregate evaluates Dream material readiness from the browser-safe aggregate data before final write validation.
* Aggregate attaches `healthStatus` and `fixHint` to the Dream branch, emitting a minimal Dream object when no output exists.
* Non-healthy Dream health states add bounded aggregate warnings.
* Runtime-state read failures degrade to a bounded warning and output freshness checks instead of failing aggregate.

**Files Changed**:

* `scripts/lib/aggregate-orchestration.ts` - attached Dream health metadata and warnings during host-local/full aggregate assembly.
* `.spec_system/specs/phase38-session03-aggregate-and-dream-health/implementation-notes.md` - recorded task evidence.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/aggregate-orchestration.test.ts`
  * Result: PASS - 1 test file passed, 22 tests passed.
  * Evidence: Existing aggregate orchestration helpers and scoped write behavior remained compatible after Dream health assembly changes.
* BQC check: PASS - Failure path completeness covered by guarded runtime-state read; contract alignment covered by health mapper and validator.
* UI product-surface check: N/A - aggregate data assembly only, no UI surface changed.
* UI craft check: N/A - aggregate data assembly only, no UI surface changed.

* `scripts/lib/aggregate-live-data-write.ts` - added Windows private path privacy patterns.
* `.spec_system/specs/phase38-session03-aggregate-and-dream-health/implementation-notes.md` - recorded task evidence.

**Verification**:

* Command/check: `bun run test -- scripts/lib/__tests__/aggregate-live-data-write.test.ts`
  * Result: PASS - 1 test file passed, 27 tests passed.
  * Evidence: Existing write-boundary validation, scoped merge, lock, and privacy checks remained compatible after adding Windows patterns.
* BQC check: PASS - Trust boundary and error information boundaries strengthened at the generated-data write gate.
* UI product-surface check: N/A - write-boundary code only, no UI surface changed.
* UI craft check: N/A - write-boundary code only, no UI surface changed.

### Task T022 - Inspect generated live-data for Dream health, redaction, ASCII/LF compliance, and platform regression evidence

**Started**: 2026-06-29 21:16 **Completed**: 2026-06-29 21:23 **Duration**: 7 minutes

**Notes**:

* Verified generated `src/data/live-data.json` contains Dream health metadata: `healthStatus: healthy`, `fixHint: Dream output is fresh.`, 4 prescriptions, and the latest Dream date.
* Initial ASCII inspection found raw Unicode source text in generated live data. Added an ASCII-safe JSON serializer at the atomic write boundary so generated files preserve parsed values while escaping non-ASCII bytes.
* Added write-boundary regression coverage proving non-ASCII extension payload content is written as JSON escapes and parses back to the original value.
* Rewrote generated data through `writeHostLocalAggregate()` after the serializer fix; Dream health stayed healthy and the file passed privacy, ASCII, and LF checks.
* Confirmed Linux host-local aggregate behavior remains compatible: optional macOS-only signals were skipped, app detection completed, Windows Terminal and Apple Terminal remained undetected on Linux, and the aggregate wrote successfully.

**Files Changed**:

* `scripts/lib/aggregate-live-data-write.ts` - added ASCII-safe generated-data JSON serialization before atomic writes.
* `scripts/lib/__tests__/aggregate-live-data-write.test.ts` - added ASCII-safe writer regression coverage.
* `src/data/live-data.json` - regenerated through `writeHostLocalAggregate()` with ASCII-safe JSON escapes and Dream health metadata.

* Command/check: `jq '{generatedAt, isExample, dreamStatus: .dream.healthStatus, appsDetected: (.detection.apps | to_entries | map(select(.value.detected == true) | .key)), terminals: .detection.apps.terminals.installed, codexStatus: .localAgents.providers.codex.status}' src/data/live-data.json`
  * Result: PASS - Generated data is non-example host-local output with Dream healthy, expected detected Linux apps, and both Windows Terminal and Apple Terminal undetected.
  * Evidence: Output showed `isExample: false`, detected apps `claudeCode`, `codex`, `gemini`, `openclaw`, and `hermes`, `windowsTerminal.detected: false`, and `appleTerminal.detected: false`.
