# Phase 2 PR #3 Checklist: History Index and Topic Search
|
|
|
|
Created: 2026-02-12
|
|
Owner: Flynn core
|
|
Status: ready to implement
|
|
|
|
## Goal
|
|
|
|
Add lightweight session history indexing to support topic/keyword search and improve future routing/context decisions.
|
|
|
|
## Scope
|
|
|
|
In scope:
|
|
- message metadata indexing (keywords/topics)
|
|
- search API over indexed history
|
|
- optional routing confidence boost hook
|
|
- gateway handlers for search and reindex
|
|
|
|
Out of scope:
|
|
- heavyweight semantic/vector history search
|
|
- UI redesign for history explorer
|
|
|
|
## Files
|
|
|
|
New:
|
|
- `src/session/indexer.ts`
|
|
- `src/session/search.ts`
|
|
- `src/session/indexer.test.ts`
|
|
- `src/session/search.test.ts`
|
|
- `src/gateway/handlers/history.ts`
|
|
|
|
Modified:
|
|
- `src/config/schema.ts`
|
|
- `src/session/store.ts`
|
|
- `src/session/manager.ts`
|
|
- `src/daemon/index.ts`
|
|
- `src/daemon/routing.ts`
|
|
- `src/gateway/handlers/index.ts`
|
|
|
|
## Implementation Steps
|
|
|
|
1. Add `history_index` config section (`enabled`, `max_keywords`, `search_limit`, etc.).
|
|
2. Extend session persistence with metadata field (migration-safe).
|
|
3. Implement indexer:
|
|
- tokenize + stopword filtering
|
|
- extract top keywords/topics
|
|
- attach metadata when messages are written
|
|
4. Implement searcher:
|
|
- query keyword overlap
|
|
- rank by relevance + recency
|
|
5. Wire into session manager lifecycle.
|
|
6. Add gateway handlers:
|
|
- `history.search`
|
|
- `history.reindex`
|
|
7. Add optional routing hook to boost confidence when query overlaps strong historical topics.
|
|
|
|
## Validation Commands
|
|
|
|
```bash
|
|
pnpm typecheck
|
|
pnpm test:run src/session/indexer.test.ts
|
|
pnpm test:run src/session/search.test.ts
|
|
pnpm test:run src/session/store.test.ts
|
|
pnpm test:run src/session/manager.test.ts
|
|
pnpm test:run src/daemon/routing.test.ts
|
|
pnpm test:run
|
|
pnpm lint
|
|
pnpm build
|
|
```
|
|
|
|
## Acceptance Criteria
|
|
|
|
- Metadata indexing persists without breaking existing sessions.
|
|
- History search returns ranked, relevant results.
|
|
- Reindex operation is safe and idempotent.
|
|
- Existing session behavior remains unchanged when feature disabled.
|
|
- Routing boost path is optional and bounded.
|
|
|
|
## Risks
|
|
|
|
- DB migration regressions on existing data.
|
|
- Mitigation: additive migration + migration tests.
|
|
- Search noise (low precision).
|
|
- Mitigation: score threshold + max result cap.
