**Started**: 2026-06-08 02:20 **Completed**: 2026-06-08 02:22 **Duration**: 2 minutes

**Notes**:

* Added bridge coverage for endpoint registration, method rejection, loopback enforcement, token checks, safe no-store headers, and live-data spend projection.
* Tested oversized request bodies, malformed JSON, empty payloads, invalid cadence payloads, valid mutations, duplicate write prevention, invalid config, and write failure mapping.
* Asserted bridge responses do not expose temp paths, token-shaped strings, raw process labels, provider payload labels, Actor/Dataset labels, or auth filenames.

**Files Changed**:

* `scripts/lib/__tests__/trend-finder-scheduler-status-bridge.test.ts` - added scheduler status bridge tests.

**BQC Fixes**:

* Duplicate action prevention: tests assert concurrent POST mutations return `write_in_flight` while the first write is held open (`scripts/lib/__tests__/trend-finder-scheduler-status-bridge.test.ts`).
* Trust boundary enforcement: tests assert method, loopback, token, body-size, JSON, and cadence validation failures are enforced at the bridge (`scripts/lib/__tests__/trend-finder-scheduler-status-bridge.test.ts`).
* Error information boundaries: tests assert invalid config and write failure responses are redacted (`scripts/lib/__tests__/trend-finder-scheduler-status-bridge.test.ts`).

**Notes**:

* Added focused helper coverage for registry cadence projection, timer intent, first-run state, command hints, and recurring spend projection.
* Tested cadence mutation validation, atomic config write behavior, unrelated job preservation, and idempotent no-op mutations.
* Covered first-run, unreadable, skipped, failed, and blocked latest-run states plus unsafe diagnostic redaction.

**Files Changed**:

* `scripts/lib/__tests__/trend-finder-scheduler-status.test.ts` - added scheduler status helper unit tests.

**BQC Fixes**:

* Contract alignment: tests assert browser-safe helper output matches the scheduler status and spend projection contracts (`scripts/lib/__tests__/trend-finder-scheduler-status.test.ts`).
* Error information boundaries: tests assert unsafe paths, token-shaped strings, logs, provider payload labels, Actor/Dataset labels, and auth filenames do not appear in browser-safe status (`scripts/lib/__tests__/trend-finder-scheduler-status.test.ts`).

**Verification**:

* `bun test ./scripts/lib/__tests__/trend-finder-scheduler-status.test.ts`

***

* Uses status roles and polite live regions for progress updates.

**Files Changed**:

* `src/extensions/trend-finder/components/live-run-progress.tsx` - created live progress component.

**BQC Fixes**:

* Accessibility and platform compliance: component uses `role="status"`, `aria-live`, labels, and non-text icon decoration (`src/extensions/trend-finder/components/live-run-progress.tsx`).

***

### Task T016 - Create scheduler status hook

**Started**: 2026-06-08 02:37 **Completed**: 2026-06-08 02:42 **Duration**: 5 minutes

**Notes**:

* Added scheduler status controls for load, poll, mutate, revalidate, and reset behavior.
* Added explicit idle/loading/ready/saving/error/offline states, pending mutation keys, and duplicate request protection.
* Revalidates after mutations and aborts outstanding requests on cleanup.

**Files Changed**:

* `src/extensions/trend-finder/use-scheduler-status.ts` - created scheduler status hook.

**BQC Fixes**:

* Resource cleanup: polling interval and abort controller are cleared on scope exit (`src/extensions/trend-finder/use-scheduler-status.ts`).
* Failure path completeness: offline and bridge error states are caller-visible (`src/extensions/trend-finder/use-scheduler-status.ts`).

***

### Task T015 - Update run-control presentation

**Started**: 2026-06-08 02:29 **Completed**: 2026-06-08 02:36 **Duration**: 7 minutes

**Notes**:

* Extended run progress to carry optional live progress snapshots.
* Updated running presentation to show current live stage, live message, and live elapsed label when available.
* Added skipped-run success presentation while preserving cancel, already-running, failed, and coarse fallback states.

**Files Changed**:

* `src/extensions/trend-finder/run-control.ts` - added live progress presentation support.

**BQC Fixes**:

* Contract alignment: run presentation consumes the same live progress view model as UI components (`src/extensions/trend-finder/run-control.ts`).
* Failure path completeness: unavailable progress falls back to coarse lifecycle messaging (`src/extensions/trend-finder/run-control.ts`).

***

### Task T014 - Poll live progress from run hook

**Started**: 2026-06-08 02:29 **Completed**: 2026-06-08 02:36 **Duration**: 7 minutes

**Notes**:

* Added live progress polling after token acquisition during active Trend Finder runs.
* Added cleanup for polling intervals, progress abort controllers, parent abort signals, reset, cancel, completion, and unmount.
* Added unavailable-progress fallback while keeping the coarse run lifecycle active.

**Files Changed**:

* `src/extensions/trend-finder/hooks/use-trend-finder-run.ts` - added live progress polling and cleanup.

**BQC Fixes**:

* Resource cleanup: intervals and abort controllers are released on all run exits and unmount (`src/extensions/trend-finder/hooks/use-trend-finder-run.ts`).
* State freshness on re-entry: reset and new runs restore progress to fresh starting/idle snapshots (`src/extensions/trend-finder/hooks/use-trend-finder-run.ts`).

***

### Task T013 - Add safe async run progress snapshots

**Started**: 2026-06-08 02:21 **Completed**: 2026-06-08 02:27 **Duration**: 6 minutes

**Notes**:

* Added `getSafeTrendFinderRunProgress` to derive browser-safe progress from async process lifecycle state.
* Mapped idle, running, completed, skipped, failed, and timed-out states to live progress without exposing captured stdout/stderr.
* Reused Engine Replay stage IDs for running and completed progress summaries.

**Files Changed**:

* `src/lib/async-trend-finder-run.ts` - added safe progress snapshot builder.

**BQC Fixes**:

* Error information boundaries: raw process errors and buffered logs stay inside the runner and are not included in safe progress (`src/lib/async-trend-finder-run.ts`).
* Contract alignment: progress snapshots use the browser live progress schema fields (`src/lib/async-trend-finder-run.ts`).

***

### Task T012 - Register scheduler bridge and status endpoint

**Started**: 2026-06-08 02:21 **Completed**: 2026-06-08 02:28 **Duration**: 7 minutes

**Notes**:

* Registered the scheduler status bridge in Vite with the shared refresh token, loopback guard, and reviewed local scheduler config path.
* Added a safe `/__run_trend_finder_status` endpoint that returns progress snapshots without raw stdout/stderr or scheduler paths.
* Updated `/__run_trend_finder` to return no-store JSON responses and include safe progress on terminal results.

**Files Changed**:

* `vite.config.ts` - registered scheduler status bridge and safe run progress endpoint.

**BQC Fixes**:

* Error information boundaries: Trend Finder run responses now use sanitized JSON and never include raw buffered process output (`vite.config.ts`).
* Trust boundary enforcement: status endpoint uses the same loopback/token checks as the run endpoint (`vite.config.ts`).

***

### Task T011 - Implement bridge GET and mutation handling

**Started**: 2026-06-08 01:58 **Completed**: 2026-06-08 02:20 **Duration**: 22 minutes

**Notes**:

* Implemented scheduler status GET loading through the safe helper with optional spend projection from parsed live data.
* Implemented scheduler cadence/timer POST mutation handling with strict schema validation and explicit status code mapping.
* Added malformed JSON, oversized body, invalid config, invalid payload, write failure, and write-in-flight response paths.

**Files Changed**:

* `scripts/lib/trend-finder-scheduler-status-bridge.ts` - implemented GET/POST scheduler status bridge behavior.

**BQC Fixes**:

* Failure path completeness: bridge responses provide explicit safe error codes for all expected failure paths (`scripts/lib/trend-finder-scheduler-status-bridge.ts`).
* External dependency resilience: bridge state loading uses bounded timeout and retry around live-data reads (`scripts/lib/trend-finder-scheduler-status-bridge.ts`).

***

### Task T010 - Add scheduler/progress view-model helpers

**Started**: 2026-06-08 02:13 **Completed**: 2026-06-08 02:19 **Duration**: 6 minutes

**Files Changed**:

* `src/extensions/trend-finder/view-model.ts` - added scheduler, checklist, and live progress view-model helpers.

**BQC Fixes**:

* Contract alignment: live progress stage labels exhaustively cover Engine Replay decision stage IDs (`src/extensions/trend-finder/view-model.ts`).
* Accessibility and platform compliance: view-models produce concise labels suitable for accessible UI summaries (`src/extensions/trend-finder/view-model.ts`).

***

### Task T009 - Extend Trend Finder schema defaults

**Started**: 2026-06-08 02:08 **Completed**: 2026-06-08 02:12 **Duration**: 4 minutes

**Notes**:

* Added additive `schedulerStatus` and `liveProgress` fields to the Trend Finder data schema with safe defaults.
* Updated typed collector and fixture constructors to include the new defaults without weakening `TrendFinderData`.
* Verified both app and script typechecks after the schema extension.

**Files Changed**:

* `src/extensions/trend-finder/schema.ts` - added scheduler status and live progress fields.
* `scripts/extensions/trend-finder/collector.ts` - added typed defaults to generated Trend Finder output.
* `src/extensions/trend-finder/fixtures.ts` - added typed defaults to fixture and empty Trend Finder data.

**Started**: 2026-06-08 02:01 **Completed**: 2026-06-08 02:07 **Duration**: 6 minutes

**Notes**:

* Added browser-side schemas and defaults for scheduler status, cadence mutation, first-run checklist items, recurring spend projection, and live run progress.
* Added bounded arrays/counts and endpoint request helpers for scheduler status and live progress.
* Kept the contract additive and resilient to malformed bridge payloads through safe parsers.

**Files Changed**:

* `src/extensions/trend-finder/scheduler-status.ts` - created browser scheduler/progress contract and request helpers.

**BQC Fixes**:

* Trust boundary enforcement: bridge responses are parsed with bounded schemas before UI use (`src/extensions/trend-finder/scheduler-status.ts`).
* Failure path completeness: request helpers map bridge failures to explicit caller-visible errors (`src/extensions/trend-finder/scheduler-status.ts`).

***

### Task T007 - Create scheduler status bridge skeleton

**Started**: 2026-06-08 01:56 **Completed**: 2026-06-08 02:00 **Duration**: 4 minutes

**Notes**:

* Added the Trend Finder scheduler status bridge endpoint with GET/POST routing.
* Reused loopback checks, token validation, bounded JSON body reads, no-store JSON responses, and safe error response mapping.
* Added a per-config write lock and safe live-data spend loading for scheduler projections.

**Files Changed**:

* `scripts/lib/trend-finder-scheduler-status-bridge.ts` - created bridge skeleton and request handler.

**BQC Fixes**:

* Trust boundary enforcement: bridge rejects non-loopback and invalid-token requests before state access (`scripts/lib/trend-finder-scheduler-status-bridge.ts`).
* Duplicate action prevention: bridge serializes config writes by config path (`scripts/lib/trend-finder-scheduler-status-bridge.ts`).
* Error information boundaries: unknown bridge failures return generic diagnostics (`scripts/lib/trend-finder-scheduler-status-bridge.ts`).

***

### Task T006 - Add recurring spend projection

**Started**: 2026-06-08 01:52 **Completed**: 2026-06-08 01:55 **Duration**: 3 minutes

**Notes**:

* Added cadence run-count projection from reviewed scheduler candidates.

* Kept projected values bounded and labeled as projections.

**Files Changed**:

* `scripts/lib/trend-finder-scheduler-status.ts` - added recurring spend projection helper.

**BQC Fixes**:

* Contract alignment: projection states keep exact/estimated/mixed/unavailable/not-applicable semantics from existing spend summaries (`scripts/lib/trend-finder-scheduler-status.ts`).

***

### Task T005 - Add cadence and timer mutation writes

**Started**: 2026-06-08 01:50 **Completed**: 2026-06-08 01:55 **Duration**: 5 minutes

**Notes**:

* Added strict mutation validation for reviewed Trend Finder cadence IDs and boolean timer intent only.
* Added writable local scheduler config validation that rejects unsafe root/job fields, unknown jobs, malformed cadence values, and non-Dream time fields.
* Added atomic temp-file writes with rename and temp cleanup on failure, preserving unrelated scheduler job entries.
* Added semantic idempotency so unchanged cadence/timer mutations do not rewrite the config.

**Files Changed**:

* `scripts/lib/trend-finder-scheduler-status.ts` - added mutation validation and atomic config writer.

**BQC Fixes**:

* Duplicate action prevention: helper returns unchanged mutations without rewriting and bridge-level locking will prevent concurrent writes (`scripts/lib/trend-finder-scheduler-status.ts`).
* Failure path completeness: malformed config, invalid payload, invalid cadence, and write failures map to explicit safe errors (`scripts/lib/trend-finder-scheduler-status.ts`).

***

**Started**: 2026-06-08 01:45 **Completed**: 2026-06-08 01:47 **Duration**: 2 minutes

**Notes**:

* Confirmed source setup bridge enforces loopback and `X-Claude-OS-Token` before state access.
* Confirmed bridge uses bounded request bodies, schema-level validation, no-store JSON responses, write locks, timeout/retry reads, and safe error mapping.
* Confirmed scheduler bridge can reuse the same `BridgeRequest`, `BridgeResponse`, `MiddlewareContainer`, and logger types.

**Files Changed**:

* `scripts/lib/trend-finder-source-setup-bridge.ts` - inspected bridge pattern to reuse.

***

### Task T002 - Verify stage taxonomy and data fields

**Started**: 2026-06-08 01:45 **Completed**: 2026-06-08 01:47 **Duration**: 2 minutes

**Notes**:

* Confirmed Engine Replay decision stages include planner, source-run, normalization, AI analysis, scoring/critic, movement, prediction, retro, and artifact writing stages.
* Confirmed source setup includes file, credential, actor, target, last-run health, diagnostics, and per-source setup status fields for checklist projection.
