## Setup (2 tasks)

Initial configuration and environment preparation.

* [x] T001 \[S2910] Verify analyzer state, completed Phase 28 prerequisite, and Session 10 stub scope before implementation (`.spec_system/PRD/phase_29/session_10_seed_candidate_review_artifact.md`)
* [x] T002 \[S2910] Inspect current canonical seed, topic identity, normalization, topic projection, private diagnostics, and collector handoff paths (`scripts/extensions/trend-finder/collector.ts`)

***

## Foundation (5 tasks)

Core structures and base implementations.

* [x] T003 \[S2910] \[P] Create seed-candidate helper contract with row schema, reason codes, bounds, deterministic ordering, and schema-validated input (`scripts/extensions/trend-finder/seed-candidates.ts`)
* [x] T004 \[S2910] \[P] Add read-only canonical seed lookup helpers for normalized alias and keyword collision checks without mutating reviewed seed arrays (`scripts/lib/ai-runtime/canonical-topic-seeds.ts`)
* [x] T005 \[S2910] \[P] Add read-only reviewed keyword lookup helpers for collision checks without enabling keyword pack writes (`scripts/extensions/trend-finder/sources/keyword-packs.ts`)
* [x] T006 \[S2910] Expose minimal weak-identity context needed by candidate generation while preserving existing resolver output and match behavior (`scripts/lib/ai-runtime/topic-identity.ts`)
* [x] T007 \[S2910] Add defaulted private diagnostics manifest artifact ID and kind entries for seed candidates with legacy manifest fallback behavior (`src/extensions/trend-finder/schema.ts`)

***

## Implementation (9 tasks)

Main feature implementation.

* [x] T008 \[S2910] Implement candidate derivation for unknown canonical IDs and repeated weak identity rows with bounded pagination, validated filters, and deterministic ordering (`scripts/extensions/trend-finder/seed-candidates.ts`)
* [x] T009 \[S2910] Implement high-quality unclustered evidence and source-local outlier candidate detection with explicit loading, empty, error, and unavailable states for missing context (`scripts/extensions/trend-finder/seed-candidates.ts`)
* [x] T010 \[S2910] Implement proposed alias and keyword normalization plus collision checks against canonical seeds and reviewed keyword packs with exhaustive reason-code handling (`scripts/extensions/trend-finder/seed-candidates.ts`)
* [x] T011 \[S2910] Implement private seed-candidate row projection with evidence IDs, source IDs, collision details, priority band, and `manual_review_required: true` (`scripts/extensions/trend-finder/seed-candidates.ts`)
* [x] T012 \[S2910] Preserve reviewed evidence attributes needed for candidate scoring without adding collection fields or widening source inputs (`scripts/extensions/trend-finder/normalize.ts`)
* [x] T013 \[S2910] Pass resolved identity and evidence context into candidate generation without changing public topic output or browser-safe topic fields (`scripts/extensions/trend-finder/topics.ts`)
* [x] T014 \[S2910] Wire collector seed-candidate generation after topic identity context exists and before diagnostics handoff with idempotency protection for repeated run assembly (`scripts/extensions/trend-finder/collector.ts`)
* [x] T015 \[S2910] Write the private `seed-candidates` artifact through diagnostics storage with atomic write behavior, temp-file cleanup, and safe warning fallback on failure (`scripts/extensions/trend-finder/private-diagnostics.ts`)
* [x] T016 \[S2910] Keep browser payload and payload-size checks limited to safe manifest metadata with no candidate rows, proposed aliases, private paths, or artifact file names (`scripts/extensions/trend-finder/measure-payload-size.ts`)

***

## Testing (4 tasks)

Verification and quality assurance.

* [x] T017 \[S2910] \[P] Add seed-candidate unit tests for unknown IDs, unclustered evidence, source-local outliers, collision checks, ordering, row bounds, and no-signal cases (`scripts/extensions/trend-finder/__tests__/seed-candidates.test.ts`)
* [x] T018 \[S2910] \[P] Add private diagnostics tests for written, skipped, and failed seed-candidate artifacts, manifest safety, path omission, and browser-slimmed payload privacy (`scripts/extensions/trend-finder/__tests__/private-diagnostics.test.ts`)
* [x] T019 \[S2910] \[P] Add collector, identity, and normalization tests proving no new collection, no canonical/keyword mutation, unchanged identity behavior, and preserved reviewed evidence context (`scripts/extensions/trend-finder/__tests__/collector.test.ts`)
* [x] T020 \[S2910] Run focused Vitest suites, payload-size check, private-artifact scan, 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 verify session completeness.

# 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-session10-seed-candidate-review-artifact/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.
