feat: two-pass retrieval with sort order and graph expansion
CI / lint-and-test (pull_request) Has been cancelled
lib/search.py — shared search library:
- Pass 1 (default): top 5 from Qdrant, score >= 0.70, no expansion
- Pass 2 (expand=True): next 5 via offset=5, score >= 0.60, plus
graph expansion from YAML frontmatter edges. Hard cap 10 total.
- Sort order: cosine desc → challenged_by → other graph-expanded
- result_type internal tag for stable sort (direct/challenge/graph)
- Module-level constants for easy threshold tuning post-calibration
- Structural file exclusion (_map.md, _overview.md)
- Within-vector dedup via _dedup_hits()
Caller updates:
- kb_retrieval.py: retrieve_vector_context() calls search(expand=True)
- diagnostics/app.py: search endpoint passes expand query param
- Argus imports from lib/search.py via sys.path (no longer owns search)
Tests: 5 new tests covering pass1-only, pass2 expansion, hard cap,
sort order, challenges-before-other-expansion.
