## Setup (3 tasks)

Initial context checks and documentation map.

* [x] T001 \[S2408] Verify Phase 24 Sessions 01-07 validation status and record any deferred items (`.spec_system/specs/phase24-session08-cross-surface-documentation-reference-mode/implementation-notes.md`)

* [x] T003 \[S2408] Build a docs update checklist from the Phase 24 documentation map and session deliverables (`.spec_system/specs/phase24-session08-cross-surface-documentation-reference-mode/implementation-notes.md`)

***

## Foundation (5 tasks)

Core manual alignment before registry and test updates.

* [x] T004 \[S2408] \[P] Update extension docs index for Reference mode, static Brief export, and local-only boundaries (`docs/extensions/README_docs-extensions.md`)
* [x] T005 \[S2408] \[P] Align scoring manual for source-local baselines, placement exclusions, bounded score lifts, and actionability bands (`docs/extensions/trend-finder-scoring.md`)
* [x] T006 \[S2408] \[P] Align pipeline manual for enrichment cache, pruning, spend accounting, scheduler status, live progress, and static export (`docs/extensions/trend-finder-pipeline.md`)
* [x] T007 \[S2408] \[P] Align sources manual for source setup, reviewed targets, source spend, cache state, and promoted/pinned handling (`docs/extensions/trend-finder-sources.md`)
* [x] T008 \[S2408] \[P] Align runtime/provenance manual for Engine Replay labels, live progress, spend, assets, and Reference mode (`docs/extensions/trend-finder-runtime-and-provenance.md`)

***

## Implementation (8 tasks)

Reference mode, UI manual, and cross-surface consistency.

* [x] T009 \[S2408] Update UI surfaces manual for Source Setup, Signal Workbench, local triage, media assets, first-run controls, live progress, and static export (`docs/extensions/trend-finder-ui-surfaces.md`)
* [x] T010 \[S2408] Cross-check manuals for implemented vs deferred labels and remove stale or example-specific product language (`docs/extensions/trend-finder-ui-surfaces.md`)
* [x] T011 \[S2408] Cross-check manuals for browser-safe boundaries around raw transcripts, source payloads, logs, billing payloads, account auth, caches, and local paths (`docs/extensions/trend-finder-runtime-and-provenance.md`)
* [x] T012 \[S2408] Update Reference mode registry labels, descriptions, source paths, and filename resolver if manuals changed with types matching declared contract and exhaustive ID handling (`src/extensions/trend-finder/reference-docs.ts`)
* [x] T013 \[S2408] Expand registry tests for updated manuals, source paths, Markdown content, local link resolution, and implemented/deferred boundary phrases with exhaustive ID coverage (`src/extensions/trend-finder/__tests__/reference-docs.test.ts`)
* [x] T014 \[S2408] Expand Markdown viewer tests for cross-doc tab links, external doc fallback, heading extraction, and accessible switch controls with platform-appropriate accessibility labels, focus management, and input support (`src/extensions/trend-finder/components/__tests__/trend-reference-doc-viewer.test.tsx`)
* [x] T015 \[S2408] Update implementation notes with changed files, doc decisions, and any intentionally deferred manual items (`.spec_system/specs/phase24-session08-cross-surface-documentation-reference-mode/implementation-notes.md`)
* [x] T016 \[S2408] Review changed docs against conventions for product naming, local-only boundaries, and current-behavior wording (`.spec_system/CONVENTIONS.md`)

***

## Testing (4 tasks)

Verification and quality assurance.

* [x] T017 \[S2408] Run focused Reference mode registry tests and record results (`src/extensions/trend-finder/__tests__/reference-docs.test.ts`)

# 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/phase24-session08-cross-surface-documentation-reference-mode/tasks.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.
