## Setup (2 tasks)

Initial configuration and environment preparation.

* [x] T001 \[S2903] Verify analyzer state, Session 02 completion, and Session 03 stub scope before editing (`.spec_system/PRD/phase_29/session_03_reception_signal_aggregate_only.md`)
* [x] T002 \[S2903] Verify collector ordering from scoring through source breakdowns and action attachment (`scripts/extensions/trend-finder/collector.ts`)

***

## Foundation (6 tasks)

Core structures and base implementations.

* [x] T003 \[S2903] \[P] Create aggregate-only reception helper contract with schema-validated metric inputs and explicit unavailable fallback (`scripts/lib/ai-runtime/reception-signal.ts`)
* [x] T004 \[S2903] Add `receptionSignal` enum, default literal, topic schema field, and optional topic typing with legacy-safe parsing (`src/extensions/trend-finder/schema.ts`)
* [x] T005 \[S2903] Add `contested-reception` risk flag plus bounded reception action cap/warning enum contracts with exhaustive schema handling (`src/extensions/trend-finder/schema.ts`)
* [x] T006 \[S2903] Prepare source-breakdown wiring types for reception assignment and deterministic risk flag merging (`scripts/lib/ai-runtime/source-breakdown.ts`)
* [x] T007 \[S2903] Prepare action-priority input parsing for reception-aware caps with schema-validated input and explicit fallback behavior (`scripts/lib/ai-runtime/action-priority.ts`)
* [x] T008 \[S2903] Add reception label, tone, description, and risk flag copy mappings with exhaustive enum handling (`src/extensions/trend-finder/view-model.ts`)

***

## Implementation (9 tasks)

Main feature implementation.

* [x] T009 \[S2903] Implement aggregate metric thresholds for endorsed, contested, ratioed, mixed, and unavailable without reading comment bodies (`scripts/lib/ai-runtime/reception-signal.ts`)
* [x] T010 \[S2903] Wire reception derivation into source breakdowns before action recommendations and merge `contested-reception` idempotently (`scripts/lib/ai-runtime/source-breakdown.ts`)
* [x] T011 \[S2903] Cap contested and ratioed reception below `act_now` with deterministic cap, warning, and calibration output (`scripts/lib/ai-runtime/action-priority.ts`)
* [x] T012 \[S2903] Add enum-only reception signal fields to sanitized collector trace summaries without raw metric or body leakage (`scripts/extensions/trend-finder/collector.ts`)
* [x] T013 \[S2903] Replace the reserved reception grid cell with projected reception values and accessible labels (`src/extensions/trend-finder/view-model.ts`)
* [x] T014 \[S2903] Preserve projected reception cells in static Brief report schema and export projection with bounded row counts (`scripts/extensions/trend-finder/static-brief-export.ts`)
* [x] T015 \[S2903] Render static Brief reception cells through existing escaped grid markup with no remote scripts or raw payload leakage (`scripts/extensions/trend-finder/static-brief-renderer.ts`)
* [x] T016 \[S2903] Include `receptionSignal` in payload pressure reporting and keep the 1 MB extension boundary explicit (`scripts/extensions/trend-finder/measure-payload-size.ts`)
* [x] T017 \[S2903] Update Trend Finder scoring docs for aggregate-only reception states, risk flag, action cap, and comment-body non-goal (`docs/extensions/trend-finder-scoring.md`)

***

## Testing (5 tasks)

Verification and quality assurance.

* [x] T018 \[S2903] \[P] Add helper and source-breakdown tests for state thresholds, unavailable fallback, body-ignored inputs, and risk flag propagation (`scripts/lib/ai-runtime/__tests__/reception-signal.test.ts`)
* [x] T019 \[S2903] \[P] Add action-priority tests proving ratioed and contested topics cannot become `act_now` while endorsed topics use normal caps (`scripts/lib/ai-runtime/__tests__/action-priority.test.ts`)
* [x] T020 \[S2903] \[P] Add schema, view-model, and grid component tests for legacy defaults, labels, tones, accessibility labels, and long text safety (`src/extensions/trend-finder/__tests__/view-model.test.ts`)
* [x] T021 \[S2903] \[P] Add static Brief and Engine Replay privacy tests for reception cells and no comment-body sentinel leakage (`scripts/extensions/trend-finder/__tests__/static-brief-export.test.ts`)
* [x] T022 \[S2903] Run focused Vitest suites, payload-size check, type checks as needed, and ASCII validation for session files (`package.json`)

***

## Completion Checklist

Before marking session complete:

* [x] All tasks marked `[x]`
* [x] All tests passing
* [x] All files ASCII-encoded
* [x] implementation-notes.md updated
* [x] Ready for the validate workflow step

***

## Next Steps

Run the validate workflow step to independently verify the completed implementation.

# 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/phase29-session03-reception-signal-aggregate-only/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.
