Before extraction, the pipeline now:
1. Identifies 3-5 themes from source (Haiku, ~$0.002/source)
2. Searches Qdrant for each theme + title (with author-stripped variant)
3. Injects "Prior Art" into extraction prompt showing existing KB claims
4. Requires ENRICHMENT/CHALLENGE to cite specific target_claim (hard gate)
Reduces near-duplicate extractions (our #1 rejection cause) by showing
the extractor what the KB already knows before it starts.
Prior art also persisted to .prior-art/ sidecar files and included in
PR body for reviewer verification.

Atomic extract-and-connect (lib/connect.py):
- After extraction writes claim files, each new claim is embedded via
OpenRouter, searched against Qdrant, and top-5 neighbors (cosine > 0.55)
are added as `related` edges in the claim's frontmatter
- Edges written on NEW claim only — avoids merge conflicts
- Cross-domain connections enabled, non-fatal on Qdrant failure
- Wired into openrouter-extract-v2.py post-extraction step
Stale PR monitor (lib/stale_pr.py):
- Every watchdog cycle checks open extract/* PRs
- If open >30 min AND 0 claim files → auto-close with comment
- After 2 stale closures → marks source as extraction_failed
- Wired into watchdog.py as check #6
Response audit system:
- response_audit table (migration v8), persistent audit conn in bot.py
- 90-day retention cleanup, tool_calls JSON column
- Confidence tag stripping, systemd ReadWritePaths for pipeline.db
Supporting infrastructure:
- reweave.py: nightly edge reconnection for orphan claims
- reconcile-sources.py: source status reconciliation
- backfill-domains.py: domain classification backfill
- ops/reconcile-source-status.sh: operational reconciliation script
- Attribution improvements, post-extract enrichments, merge improvements
