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.

The Single Idea

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.

01 Status

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.

The new joins are context, not proof. Source-backed workflow tools do not become learner proficiency, and local synthetic evaluator fixtures do not become measured learner outcomes.
02 What Changed

Coverage Now Matches The Repaired Universe

Vector reconciliationFrozen top-worked gaps now match repaired overlays when exact vectors exist.
ProvenanceRows preserve original chunk id, text hash, and title when a repaired vector is used.
Tool contextCanonical workflow and tool evidence join into source-backed candidate context.
Proof fixturesLocal evaluator fixtures join only when source-backed and runtime-safe.

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.

03 Current Proof

The Receipt Is Valid And Conservative

SignalCurrent meaning
frozen_corpusOriginal clean chunk has an exact vector.
repaired_overlayOriginal top-worked row had noisy title text, but a repaired derived chunk has an exact vector and original refs.
proxy_contextUseful source-backed context exists, but it is not learner proof.
04 Review

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.

06 Next Slice

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.

Where to start

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.
