Proof-Tail Context Repair

The proof-tail lane is now cumulative and uses real JD/workflow context refs without relaxing title-authority or generic-family gates.

The Single Idea

The proof-tail fixture lane is now cumulative and context-aware. It keeps prior supplemental fixtures, adds rows backed by strong JD/workflow context refs, and leaves only real title-authority or generic-family repair cases blocked.

01 · What Changed

Cumulative Fixtures, Real Context Refs

The command now retains existing proof-tail fixtures already joined into coverage, then adds new fixtures for current gap rows only when they pass the same local-only/source-backed gate.

The new allowance is narrow: if source_record_ref_count is stale or zero, the row can still pass only when it has at least three strong JD/workflow/named-tool context refs. Title-authority-missing and generic-family rows still block.

Where To Start

Create the title-authority and generic-family repair lane for the remaining 20 rows. Do not use broad aliases or embeddings as a shortcut.
