**Notes**:

* Added scan trigger and scan status route coverage under root and `/api` prefixes.
* Added validation coverage for invalid scope, mode, root, and unsafe Quest ignore patterns.
* Added duplicate in-flight conflict coverage using a blocked injected command runner.
* Updated unsupported-route expectations so shipped scan routes are no longer listed as planned unsupported routes while analyze and project-scan remain planned.
* Verified with `npx vitest run apps/server/tests/suggestionRoutes.test.ts apps/server/tests/unsupportedRoutes.test.ts`.

**Files Changed**:

* `apps/server/tests/suggestionRoutes.test.ts` - Added scan route behavior, validation, and duplicate-trigger coverage.

* Trust boundary enforcement: route tests assert unsafe scan request fields are rejected without echoing unsafe input (`apps/server/tests/suggestionRoutes.test.ts`).
* Contract alignment: route tests assert root and `/api` scan routes return protocol-style scan status responses (`apps/server/tests/suggestionRoutes.test.ts`).

***

### Task T021 - Write Scan Orchestrator Tests

**Started**: 2026-06-10 09:01 **Completed**: 2026-06-10 09:03 **Duration**: 2 minutes

**Notes**:

* Added tests for full scan orchestration, diff scan changed-file selection, cached TODO-family issue reuse, fallback-to-full behavior, commit tracking, ignored path exclusion, status updates, and non-blocking stale startup scans.
* Used injected git and command runners with temporary approved roots so tests do not invoke real local tooling.
* Verified the new test with `npx vitest run apps/server/tests/codebaseScanOrchestrator.test.ts`.

**Files Changed**:

* `apps/server/tests/codebaseScanOrchestrator.test.ts` - Added scan orchestrator coverage.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/tasks.md` - Marked T021 complete.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/implementation-notes.md` - Logged scan orchestrator test completion.

**BQC Fixes**:

* External dependency resilience: tests inject bounded git and command runners instead of invoking local tools (`apps/server/tests/codebaseScanOrchestrator.test.ts`).
* State freshness on re-entry: tests assert diff scans re-read current git status and previous manager state (`apps/server/tests/codebaseScanOrchestrator.test.ts`).
* Contract alignment: tests assert manager-owned status and `suggestion_update` events reflect scan mutations (`apps/server/tests/codebaseScanOrchestrator.test.ts`).

***

### Task T020 - Write Quest Ignore Tests

**Started**: 2026-06-10 08:59 **Completed**: 2026-06-10 09:01 **Duration**: 2 minutes

**Notes**:

* Added focused tests for pattern normalization, unsafe pattern rejection, path normalization, ignore-file loading, merged request patterns, and matched path exclusion.

* `apps/server/tests/questIgnore.test.ts` - Added Quest ignore helper coverage.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/tasks.md` - Marked T020 complete.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/implementation-notes.md` - Logged Quest ignore test completion.

**BQC Fixes**:

* Trust boundary enforcement: tests assert unsafe absolute, traversal, backslash, NUL, too-long, and non-ASCII patterns are rejected (`apps/server/tests/questIgnore.test.ts`).
* Contract alignment: tests assert file and request patterns merge into deterministic relative-path matching (`apps/server/tests/questIgnore.test.ts`).

***

***

### Task T017 - Wire Settings Scan Action

**Started**: 2026-06-10 02:24 **Completed**: 2026-06-10 02:25 **Duration**: 1 minute

**Notes**:

* Wired the Settings scan action to send persisted Quest ignore patterns to the scan client.
* Added an in-handler duplicate guard in addition to the disabled button state.
* Existing loading, success, error, and offline scan feedback paths remain active.

**Files Changed**:

* `apps/web/src/components/SettingsDrawer.tsx` - Sent Quest ignore patterns with scan requests and guarded duplicate scan calls.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/tasks.md` - Marked T017 complete.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/implementation-notes.md` - Logged scan action wiring.

**BQC Fixes**:

* Duplicate action prevention: the scan handler returns early while a scan is already running (`apps/web/src/components/SettingsDrawer.tsx`).
* Failure path completeness: existing explicit error and offline UI states continue to handle scan failures (`apps/web/src/components/SettingsDrawer.tsx`).

***

### Task T016 - Add Settings Quest Ignore Field

**Started**: 2026-06-10 02:24 **Completed**: 2026-06-10 02:25 **Duration**: 1 minute

**Notes**:

* Added an accessible multiline Quest ignore pattern field to Settings.
* Revalidated local scan feedback by resetting the drawer-local scan state each time Settings opens.

**Files Changed**:

* `apps/web/src/components/SettingsDrawer.tsx` - Added Quest ignore pattern textarea and drawer re-entry reset.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/tasks.md` - Marked T016 complete.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/implementation-notes.md` - Logged Settings UI field implementation.

**BQC Fixes**:

* State freshness on re-entry: scan feedback resets when the drawer opens (`apps/web/src/components/SettingsDrawer.tsx`).

***

### Task T015 - Emit Updates And De-list Scan Routes

**Started**: 2026-06-10 02:23 **Completed**: 2026-06-10 02:24 **Duration**: 1 minute

**Notes**:

* Scan status transitions emit canonical suggestion update events through the existing suggestion broadcast helper.
* Issue replacement is followed by a status update emission so snapshots contain both fresh issues and final status.
* Removed shipped scan route prefixes from planned unsupported-route classification while keeping analyze and project-scan planned.

**Files Changed**:

* `apps/server/src/lib/codebaseScanOrchestrator.ts` - Emits suggestion updates after status and issue mutations.
* `apps/server/src/lib/unsupportedRoutes.ts` - Removed scan route prefixes from planned unsupported routes.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/tasks.md` - Marked T015 complete.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/implementation-notes.md` - Logged update emission and unsupported route changes.

**BQC Fixes**:

* Contract alignment: emitted snapshots are manager-owned `suggestion_update` payloads (`apps/server/src/lib/codebaseScanOrchestrator.ts`).
* Failure path completeness: failed scans also emit a final failed status snapshot (`apps/server/src/lib/codebaseScanOrchestrator.ts`).

***

### Task T014 - Add Scan Trigger And Status Routes

**Started**: 2026-06-10 02:22 **Completed**: 2026-06-10 02:23 **Duration**: 1 minute

**Notes**:

* Added `GET /suggestions/scan/status` and `POST /suggestions/scan` under the shared suggestions router.
* Validated codebase scope, scan mode, `?full=true`, optional root, and Quest ignore patterns.
* Duplicate in-flight scans return a compact 409 conflict.

**Files Changed**:

* `apps/server/src/routes/suggestions.ts` - Added scan status and trigger handlers plus validation helpers.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/tasks.md` - Marked T014 complete.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/implementation-notes.md` - Logged scan route implementation.

**BQC Fixes**:

* Duplicate action prevention: route conflicts while the orchestrator has an in-flight scan (`apps/server/src/routes/suggestions.ts`).
* Trust boundary enforcement: route validation rejects unsupported scope, mode, root, and unsafe ignore patterns (`apps/server/src/routes/suggestions.ts`).
* Error information boundaries: conflict and validation responses do not echo request bodies or local roots (`apps/server/src/routes/suggestions.ts`).

***

### Task T013 - Wire Startup Stale Scan Lifecycle

**Started**: 2026-06-10 02:22 **Completed**: 2026-06-10 02:23 **Duration**: 1 minute

**Notes**:

* Instantiated the codebase scan orchestrator in server creation and scheduled stale startup scans after route setup.
* Kept startup scans disabled under `NODE_ENV=test` unless a test opts in.
* Destroy now clears scan timers and recovers running status before destroying the suggestion manager.

**Files Changed**:

* `apps/server/src/server.ts` - Wired scan orchestrator construction, route dependency injection, startup scheduling, and shutdown cleanup.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/tasks.md` - Marked T013 complete.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/implementation-notes.md` - Logged server startup lifecycle wiring.

**BQC Fixes**:

* Resource cleanup: pending startup scan timers are cleared on shutdown (`apps/server/src/lib/codebaseScanOrchestrator.ts`).
* Failure path completeness: shutdown recovers a running scan status to failed instead of leaving it stuck (`apps/server/src/lib/codebaseScanOrchestrator.ts`).

***

### Task T012 - Implement Diff Scan Selection And Cache Reuse

**Started**: 2026-06-10 02:21 **Completed**: 2026-06-10 02:21 **Duration**: 1 minute

**Notes**:

* Diff scans now require a previous scan commit and cached TODO-family issues.
* Changed-file subsets run through the scanner while cached TODO-family issues for unchanged, non-ignored files are reused.
* Missing previous commit or cache falls back to a full scan.

**Files Changed**:

* `apps/server/src/lib/codebaseScanOrchestrator.ts` - Added diff selection, TODO cache reuse, and full fallback behavior.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/tasks.md` - Marked T012 complete.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/implementation-notes.md` - Logged diff scan implementation.

**BQC Fixes**:

* State freshness on re-entry: diff scans re-read manager state and git state for each run (`apps/server/src/lib/codebaseScanOrchestrator.ts`).
* Contract alignment: reused cached issues are still protocol-valid manager issues and ignored files are excluded before replacement (`apps/server/src/lib/codebaseScanOrchestrator.ts`).

***

### Task T011 - Implement Git Helper Logic

**Started**: 2026-06-10 02:20 **Completed**: 2026-06-10 02:21 **Duration**: 1 minute

**Notes**:

* Added current HEAD lookup and changed-file discovery from `git status` plus committed diffs since the last scanned commit.
* Normalized git file paths before use and filtered ignored paths before diff scans.

**Files Changed**:

* `apps/server/src/lib/codebaseScanOrchestrator.ts` - Added bounded git command runner and changed-file parsing.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/tasks.md` - Marked T011 complete.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/implementation-notes.md` - Logged git helper implementation.

**BQC Fixes**:

* External dependency resilience: git commands use timeouts and bounded output (`apps/server/src/lib/codebaseScanOrchestrator.ts`).
* Error information boundaries: git failures are reduced to stable status behavior and compact messages, not raw stdout or stderr (`apps/server/src/lib/codebaseScanOrchestrator.ts`).

***

### Task T010 - Implement Full Scan Orchestration

**Started**: 2026-06-10 02:20 **Completed**: 2026-06-10 02:21 **Duration**: 1 minute

**Notes**:

* Full and daily scans now run TODO, git status, lint, build/typecheck, and test scanners through the orchestrator.
* Scanner timeout, bounded output, caps, root rejection, and compact failure behavior stay delegated to the Session 06 scanner boundary.

**Files Changed**:

* `apps/server/src/lib/codebaseScanOrchestrator.ts` - Added full scan orchestration over all codebase issue scanners.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/tasks.md` - Marked T010 complete.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/implementation-notes.md` - Logged full scan orchestration.

**BQC Fixes**:

* Failure path completeness: root rejection and scanner failures map to failed scan status or compact scanner failures (`apps/server/src/lib/codebaseScanOrchestrator.ts`).
* External dependency resilience: command scanner timeouts and output bounds remain enforced by the scanner layer (`apps/server/src/lib/codebaseIssueScanners.ts`).

***

### Task T009 - Extend Scan Client Request Model

**Started**: 2026-06-10 02:19 **Completed**: 2026-06-10 02:20 **Duration**: 1 minute

**Notes**:

* Updated the web scan client to post to `/suggestions/scan?full=true` with `scope`, `forceFull`, root, and Quest ignore patterns.
* Added status-style response parsing while preserving compatibility with file and issue array counts.

**Files Changed**:

* `apps/web/src/lib/scanCodebase.ts` - Added Quest scan request payload and status response parsing.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/tasks.md` - Marked T009 complete.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/implementation-notes.md` - Logged scan client implementation.

**BQC Fixes**:

* Error information boundaries: response summaries sanitize server-provided text and do not include the configured root path (`apps/web/src/lib/scanCodebase.ts`).
* Contract alignment: the client accepts both status-style scan route responses and legacy count-bearing scan shapes (`apps/web/src/lib/scanCodebase.ts`).

***

### Task T008 - Add Quest Ignore Settings State

**Started**: 2026-06-10 02:18 **Completed**: 2026-06-10 02:19 **Duration**: 1 minute

**Notes**:

* Added persisted `questIgnorePatterns` state, defaults, hydration, setter, and reset behavior.
* Normalized multiline input before store mutation and persistence with line, text, and per-line bounds.

**Files Changed**:

* `apps/web/src/store/useSettingsStore.ts` - Added Quest ignore Settings state and normalization.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/tasks.md` - Marked T008 complete.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/implementation-notes.md` - Logged Settings state implementation.

**BQC Fixes**:

* State freshness on re-entry: persisted snapshots are normalized during hydration and reset returns the field to default (`apps/web/src/store/useSettingsStore.ts`).
* Trust boundary enforcement: the browser bounds multiline input before it is sent to the server (`apps/web/src/store/useSettingsStore.ts`).

***

### Task T007 - Add Manager-Owned Issue Replacement

**Started**: 2026-06-10 02:18 **Completed**: 2026-06-10 02:18 **Duration**: 1 minute

**Notes**:

* Added `replaceCodebaseIssues` to validate every issue before mutation, dedupe by manager issue key, apply protocol caps, and replace scan-owned state in one mutation.
* Existing manager rollback behavior protects the previous store if validation or replacement fails.

**Files Changed**:

* `apps/server/src/managers/suggestionManager.ts` - Added atomic codebase issue replacement support.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/tasks.md` - Marked T007 complete.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/implementation-notes.md` - Logged manager replacement implementation.

**BQC Fixes**:

* Concurrency safety: replacement uses the manager mutation guard and rollback path (`apps/server/src/managers/suggestionManager.ts`).
* Contract alignment: all replacement inputs are parsed through protocol validation before store mutation (`apps/server/src/managers/suggestionManager.ts`).

***

### Task T006 - Extend Scanner Options

**Started**: 2026-06-10 02:17 **Completed**: 2026-06-10 02:18 **Duration**: 1 minute

**Notes**:

* Added normalized `changedFiles` support and `ignorePath` predicates to scanner options.
* Applied ignore filtering before TODO source-file loading and after command-output issue parsing.
* Kept deterministic ordering for changed-file subsets and filtered command issues.

**Files Changed**:

* `apps/server/src/lib/codebaseIssueScanners.ts` - Added changed-file and ignore filtering support.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/tasks.md` - Marked T006 complete.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/implementation-notes.md` - Logged scanner option implementation.

**BQC Fixes**:

* Trust boundary enforcement: unsafe changed-file paths are discarded during scanner option normalization (`apps/server/src/lib/codebaseIssueScanners.ts`).
* Contract alignment: command-backed issue filtering uses the same normalized issue paths as the persisted protocol contract (`apps/server/src/lib/codebaseIssueScanners.ts`).

***

### Task T005 - Create Scan Orchestrator Lifecycle Boundary

**Started**: 2026-06-10 02:16 **Completed**: 2026-06-10 02:18 **Duration**: 2 minutes

**Notes**:

* Added a `CodebaseScanOrchestrator` with single-flight scan execution, status transitions, update broadcasts, stale startup scheduling, and shutdown cleanup.
* Added bounded git command helpers for head and changed-file discovery without persisting raw command output.

**Files Changed**:

* `apps/server/src/lib/codebaseScanOrchestrator.ts` - Added scan orchestration boundary, status lifecycle, git helpers, and cleanup hooks.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/tasks.md` - Marked T005 complete.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/implementation-notes.md` - Logged orchestrator lifecycle implementation.

**BQC Fixes**:

* Duplicate action prevention: scan execution is single-flight and duplicate callers receive an in-flight error (`apps/server/src/lib/codebaseScanOrchestrator.ts`).
* Resource cleanup: startup timers are cleared and running status is recovered on destroy (`apps/server/src/lib/codebaseScanOrchestrator.ts`).
* External dependency resilience: git helpers use timeouts and bounded output (`apps/server/src/lib/codebaseScanOrchestrator.ts`).

***

### Task T004 - Create Quest Ignore Helpers

**Started**: 2026-06-10 02:15 **Completed**: 2026-06-10 02:16 **Duration**: 1 minute

**Notes**:

* Added `.factionos-questignore` loading, request pattern normalization, deduping, bounds, and deterministic path matching.
* Rejected absolute paths, parent traversal, backslashes, NUL bytes, non-ASCII patterns, and empty path segments before matching.

**Files Changed**:

* `apps/server/src/lib/questIgnore.ts` - Added Quest ignore normalization, file loading, and matcher utilities.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/tasks.md` - Marked T004 complete.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/implementation-notes.md` - Logged helper implementation.

**BQC Fixes**:

* Trust boundary enforcement: unsafe ignore patterns are rejected before they can affect scan scope (`apps/server/src/lib/questIgnore.ts`).
* Error information boundaries: ignore file read failures expose only stable error codes, not file contents or raw paths in responses (`apps/server/src/lib/questIgnore.ts`).

***

### Task T003 - Verify Web Settings Scan Baseline

**Started**: 2026-06-10 02:15 **Completed**: 2026-06-10 02:15 **Duration**: 1 minute

**Notes**:

* Confirmed `scanRoot` persistence, hydration, setter, and reset behavior are already present in the Settings store.
* Confirmed `runCodebaseScan` currently posts to the compatibility `/llm/scan-codebase` route and sanitizes local failures.
* Confirmed `SettingsDrawer` keeps scan state local, prevents empty-root scans, disables duplicate clicks while scanning, and renders compact status feedback.

**Files Changed**:

* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/tasks.md` - Marked T003 complete.
* `.spec_system/specs/phase18-session07-scan-orchestration-and-quest-ignore-patterns/implementation-notes.md` - Logged web baseline verification.

# 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://faction-os.gitbook.io/faction-os-docs/.spec_system/archive/sessions/phase18-session07-scan-orchestration-and-quest-ignore-patterns/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.
