Session Search

Use transcripts as receipts. Do not guess from memory when session history can answer.

Source order

1. Use flowing recall for every memory request.
2. When recall reports No projection head, call discover_scopes, choose one returned exact pair, and retry recall.
3. Read supporting flowing observations and their evidence references.
4. Search native sessions only when exact transcript evidence remains necessary.
5. Verify capture health before claiming Central has the runtime history.

Flowing scope is exact. project is the persisted repository identity, commonly owner.repo. workstream is the persisted branch or bookmark, commonly main or default. A No projection head result means the scope is wrong or empty. Use persisted discover_scopes candidates to correct it. Never synthesize a pair from separate hints or fall back to raw transcripts.

Flowing recall has exactly three lanes:

1. flowing-reflections
2. flowing-observations
3. curated-pages
