## 3. ASCII Encoding Check

### Status: PASS

| File Set                                                               | Encoding | Line Endings | Status |

| Supporting changed implementation, fixture, e2e, and schema test files | ASCII    | LF           | PASS   |
| Session spec artifacts                                                 | ASCII    | LF           | PASS   |

### Encoding Issues

None.

## 4. Test Results

### Status: PASS

| Metric      | Value         |
| ----------- | ------------- |
| Total Tests | 3725          |
| Passed      | 3725          |
| Failed      | 0             |
| Coverage    | Not collected |

### Commands Run

* `bun run test` - PASS, 315 test files and 3725 tests.
* `bun run typecheck` - PASS.
* `bun run typecheck:scripts` - PASS.
* `bun run lint` - PASS.
* `bun run scripts/extensions/trend-finder/measure-payload-size.ts src/data/live-data.example.json --threshold-kb=1024` - PASS, `extensions.items["trend-finder"].data` is 14,138 bytes under the 1,048,576 byte boundary.
* `git diff --check` - PASS.
* ASCII/CRLF validation across changed and untracked files - PASS.

### Failed Tests

None after remediation. During validation, the first full `bun run test` surfaced one stale assertion in `src/lib/__tests__/trend-finder-schema.test.ts` expecting `topic-006` to only carry `research-only`; the fixture now legitimately includes `contested-reception`. The assertion was updated and the full suite passed.

## 5. Database/Schema Alignment

### Status: N/A

N/A - this session introduced no DB-layer changes, migrations, persisted hosted storage, schema DDL, seed database changes, or ORM metadata updates.

### Issues Found

N/A - no DB-layer changes.

***

## 6. Success Criteria

From spec.md:

### Functional Requirements

* [x] `receptionSignal` defaults to `unavailable` for legacy or unsupported payloads.
* [x] A high-engagement hostile-ratio fixture resolves to `ratioed`, receives `contested-reception`, and cannot produce `act_now`.
* [x] Topics with no defensible aggregate metric remain `unavailable`.
* [x] Endorsed or mixed aggregate cases render as bounded labels without suppressing valid evidence rows.
* [x] Live and static polarity grids show reception values instead of the Session 03 placeholder.

### Testing Requirements

* [x] Unit tests written and passing for reception derivation, source-breakdown wiring, and action caps.
* [x] Schema/view-model/component tests cover legacy defaults, labels, tones, accessibility labels, and long text safety.
* [x] Static Brief export/renderer tests cover projected reception cells and privacy scan behavior.
* [x] Engine Trace tests prove no comment-body sentinel reaches sanitized trace output.
* [x] Focused test commands recorded in implementation notes during the implement step.

### Non-Functional Requirements

* [x] Browser payload stays under the 1 MB extension budget.
* [x] Static Brief and Engine Replay remain browser-safe and do not expose raw source rows, private paths, prompts, provider responses, or comment bodies.
* [x] No new source, collector, media boundary, database, or hosted storage path is introduced.

### Quality Gates

* [x] All files ASCII-encoded.
* [x] Unix LF line endings.
* [x] Code follows project conventions.
* [x] New enum branches use exhaustive handling and explicit fallback behavior.

## 7. Conventions Compliance

### Status: PASS

| Category       | Status | Notes                                                                                                                   |
| -------------- | ------ | ----------------------------------------------------------------------------------------------------------------------- |
| Naming         | PASS   | `receptionSignal`, `contested-reception`, and `contested_reception` follow nearby enum naming patterns.                 |
| File Structure | PASS   | Runtime helper, tests, UI projection, static Brief, and docs live in established Trend Finder locations.                |
| Error Handling | PASS   | Malformed reception inputs default to `unavailable`; malformed action inputs keep the established safe review fallback. |
| Comments       | PASS   | No noisy commented-out code added.                                                                                      |
| Testing        | PASS   | Focused tests live alongside runtime, script, component, schema, and e2e behavior they cover.                           |

### Convention Violations

None.

| Contract alignment | PASS   | Schema, runtime helper, action cap, trace parser, static Brief projection, and tests share the new enum contract. |                                                                                         |

### Violations Found

None.

### Fixes Applied During Validation

* Updated `src/lib/__tests__/trend-finder-schema.test.ts` so `topic-006` expects the new `contested-reception` risk flag alongside `research-only`.

## Validation Result

### PASS

Session 03 validates successfully. The implementation adds aggregate-only reception state, propagates contested reception risk, prevents contested/ratioed topics from producing `act_now`, replaces reserved live/static reception grid cells, and keeps trace/static payloads bounded and privacy-safe.

### Required Actions

None.

## Next Steps

Run updateprd to mark session complete.

## 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/validation.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.
