AI Fluency Coverage, Tool Context, Proof Fixture, And Vector Reconciliation Handoff
The top-band capability receipt now matches repaired vector reality, adds conservative tool and proof context, and keeps runtime authority locked.
This checkpoint turns the AI Fluency top-band receipt from a partial coverage ledger into a stronger production-readiness surface: exact vectors are complete for top 500 and top 1,000, repaired overlays are visible, tool context and local synthetic proof fixtures are joined, and production unlock remains zero.
Local Production-Readiness Slice Complete
The top 500 and top 1,000 ICP/title hardening cohorts now have complete exact Gemini vector coverage in the capability coverage receipt. The receipt counts repaired top-worked-title overlays transparently, instead of treating the original noisy chunks as clean.
Coverage Now Matches The Repaired Universe
The implementation also split workflow and tool status counts, closed DuckDB connections explicitly, softened the receipt status to coverage_receipt_ready_capability_hardening_required, and added tests for repaired vectors and punctuation-normalized title matching.
The Receipt Is Valid And Conservative
uv run aina-data-engine --root /srv/aina/aina-data-engine-room ai-fluency-capability-coverage
| Signal | Current meaning |
|---|---|
frozen_corpus | Original clean chunk has an exact vector. |
repaired_overlay | Original top-worked row had noisy title text, but a repaired derived chunk has an exact vector and original refs. |
proxy_context | Useful source-backed context exists, but it is not learner proof. |
Subagents And Claude Challenged The Patch
Three read-only Codex explorers isolated the vector mismatch, tool/proof join surfaces, and AIN-510 blocker set. Claude CLI then challenged status wording, fixture-count trust, brittle normalization, provenance exposure, and connection handling. Those findings were addressed before validation.
All three subagents have been closed, so the next run has headroom.

Promote Runtime Only After AIN-510 Proof
AIN-510 remains blocked by stale_vector_count: 10, the missing sensitive mismatch fixture suite, and missing rollback proof. The next slice should add deterministic local mismatch fixtures, prove rollback to deterministic fallback, reconcile stale vectors, then expand remaining tool and proof context gaps.

Start with the AIN-510 mismatch-suite and rollback-proof slice. The vectors are now top-band complete; runtime authority is the thing still correctly locked.
