Top-Band Abstain Semantic Bridge Handoff
Three source-backed abstains moved into caveated local fallback. Everything sensitive stayed held.
The three abstain rows that survived hardening now have a second proof layer: semantic QA plus a caveated runtime contract bridge. They move from raw abstain to local fallback only, while sensitive rows, repair-first rows, and confirmation-required rows stay held.
What Changed
Added top_band_abstain_semantic_qa_v1 and top_band_abstain_contract_bridge_v1. The semantic QA lane consumes hardening candidates and requires source evidence, clean guardrails, and responsibility snippets that support the title.
The bridge lane consumes only QA pass rows and JD-aware role context, then emits caveated local fallback rows for production runtime contracts. These rows are intentionally not serve-now promotions.
Live Counts
| Metric | Count | Meaning |
|---|---|---|
| Semantic QA candidates | 3 | The hardening-approved bridge candidates. |
| Semantic QA passed | 3 | Rows allowed into the bridge. |
| Contract bridge rows | 3 | Caveated local fallback rows added to runtime contracts. |
| Remaining repair queue rows | 27 | Rows still held as abstain. |
Before this slice, the top-1,000 route mix was 944 serve, 22 fallback, and 30 abstain. This slice shifted only the 3 QA-passing rows into fallback.

Added two source modules, two focused test files, four validation receipts, four report companions, and this handoff pair. Updated CLI/report wiring, production runtime contracts, artifact allowlisting, tests, and regenerated downstream route/runtime receipts.

Artifact policy proof confirmed that durable validation and report receipts are trackable while bulk DuckDB/vector artifacts remain ignored.
Next Move
The next production-readiness slice should work the 27 remaining abstains by category: keep case manager confirmation-required, repair the 8 repair-first rows from existing source authority, hold the 18 sensitive-policy rows until a regulated-role policy lane exists, and continue JD-aware role-context coverage instead of title-only repairs.

Start with the 27 remaining abstains, but preserve the hard boundary: repair or policy first, bridge only after source-backed semantic proof.
