### Failed Tests

None.

## 5. Database/Schema Alignment

### Status: N/A

*N/A because the session introduced no database, migration, ORM, seed, or persisted server-side schema changes. The schema work is limited to Zod browser/runtime data contracts under `src/extensions/trend-finder/schema.ts`.*

### Issues Found

N/A - no DB-layer changes.

***

## 6. Success Criteria

From `spec.md`:

### Functional Requirements

* [x] Existing next-run prediction records, retro rows, and calibration fields parse and render unchanged.
* [x] Dated predictions include target date, lifecycle at filing, target lifecycle, display horizon, cited evidence IDs, and provenance.
* [x] Deterministic fallback produces dated calls without AI and without invented source IDs, evidence IDs, or private metadata.
* [x] Dated predictions grade only on or after their target date; earlier runs keep them pending and not stale.
* [x] Due dated predictions use existing hit/partial/miss/pending outcomes and preserve `future-run` versus `backtest` mode distinction.
* [x] Story Log stays bounded, browser-safe, and sorted deterministically with verdict and due-state filtering.
* [x] Brief and Watchlist expose prediction history without raw archives, private paths, prompt text, provider responses, or unbounded cache rows.

### Testing Requirements

* [x] Prediction tests cover dated fallback buckets, valid AI rows, invalid target dates, unknown lifecycle stages, unknown evidence IDs, and legacy archive parsing.
* [x] Retro tests cover before-target pending, on-target grading, after-target stale behavior, topic disappearance, mode preservation, and calibration counts.
* [x] Collector tests cover Story Log projection bounds, archive merge ordering, sanitized trace counters, and fallback behavior when archives are absent or malformed.
* [x] Schema tests cover additive defaults, max-array bounds, malformed Story Log rows, and old payload compatibility.
* [x] View-model and component tests cover filter counts, reset behavior, empty states, accessible labels, and deterministic row ordering.

### Quality Gates

* [x] All files ASCII-encoded.
* [x] Unix LF line endings.
* [x] Code follows project conventions.
* [x] Focused and full tests pass.
* [x] Browser payload remains bounded; `src/data/live-data.example.json` is 46,117 bytes, under the 1 MB payload limit.
* [x] No new source adapter, credential, AI provider, public collection path, third-party transfer, or bridge endpoint introduced.
* [x] Private prediction and retro archives remain local and never appear as raw browser or static-export content.
* [x] Watchlist and Brief UI remain dense, stable, mobile-safe, and free of obvious horizontal-overflow risks.

## 7. Conventions Compliance

### Status: PASS

| Category       | Status | Notes                                                                                                          |
| -------------- | ------ | -------------------------------------------------------------------------------------------------------------- |
| Naming         | PASS   | New names use Trend Finder prediction/retro/Story Log vocabulary and avoid new global `findtrend` identifiers. |
| File Structure | PASS   | Runtime code, extension UI, tests, fixtures, and schema changes stay in established locations.                 |
| Error Handling | PASS   | AI validation rejects malformed rows; archives continue to degrade through warnings/fallbacks.                 |
| Comments       | PASS   | No obvious commented-out code or noisy comments added.                                                         |
| Testing        | PASS   | Focused tests were added close to runtime, collector, schema, view-model, and component behavior.              |
| Data           | PASS   | Example data remains browser-safe and bounded; generated private runtime data remains out of git.              |

### Convention Violations

None in session-touched files.

## 8. Security & GDPR Compliance

### Status: PASS

**Full report**: See `security-compliance.md` in this session directory.

#### Summary

| Area     | Status | Findings |
| -------- | ------ | -------- |
| Security | PASS   | 0 issues |
| GDPR     | N/A    | 0 issues |

### Critical Violations

None.

## 9. Behavioral Quality Spot-Check

### Status: PASS

**Checklist applied**: Yes **Files spot-checked**:

* `scripts/lib/ai-runtime/predictions.ts`
* `scripts/lib/ai-runtime/retros.ts`
* `scripts/extensions/trend-finder/collector.ts`
* `src/extensions/trend-finder/view-model.ts`
* `src/extensions/trend-finder/components/story-log-panel.tsx`

| Category           | Status | File                                       | Details                                                                                                                        |
| ------------------ | ------ | ------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------ |
| Trust boundaries   | PASS   | `predictions.ts`, `retros.ts`, `schema.ts` | AI output target dates, lifecycle stages, evidence IDs, enums, and string lengths are validated before records are accepted.   |
| Resource cleanup   | PASS   | `collector.ts`                             | No new timers, subscriptions, sockets, or long-lived resources were introduced.                                                |
| Mutation safety    | PASS   | `collector.ts`, `story-log-panel.tsx`      | Story Log projection is deterministic and bounded; UI filter state resets when row signatures change.                          |
| Failure paths      | PASS   | `retros.ts`, `collector.ts`                | Not-yet-due rows are preserved through fallback paths; invalid archives and writes continue to surface warnings.               |
| Contract alignment | PASS   | `schema.ts`, `view-model.ts`, tests        | Runtime, schema, fixture, view-model, Watchlist, Brief, backtest, and replay contracts include the additive `storyLog` branch. |

### Violations Found

None.

### Fixes Applied During Validation

* Added Story Log view-model and component tests for sparse legacy rows, partial/miss/undated/resolved filter counts, direct due-state/outcome labels and tones, and the panel danger tone path.
* Reran coverage after the fix; branch coverage improved from 75.96% to 76.01%, satisfying the 76% threshold.

## Validation Result

### PASS

All validation checks passed after the coverage fix. The session is ready for the `updateprd` workflow step.

### Required Actions

None.

## Next Steps

Run `updateprd` to mark `phase27-session08-dated-predictions-and-story-log` 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/phase27-session08-dated-predictions-and-story-log/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.
