bvandeusenandClaude Opus 5	a01deeb851	fix(shapes): the signature basis admits the band true instances score in (#4306) ... Measured over 459 judged instance rows against every same-family canon: true instances score 1.0 or ~0.795 (a model whose mixin list differs from the canon's), and 0.8 cut the second band entirely. The proposal is read before it is confirmed, so the floor admits it: 0.75 takes every measured true row, at 35 wrong-canon pairings instead of 14.

bvandeusenandClaude Opus 5	312dc9f6f7	fix(shapes): the semantic arm proposes at the write-path floor, not a private 0.8 (#4208) ... 0.8 was sized for proposals nobody reads; every semantic proposal is read by a judge before it is confirmed. Measured, it proposed 0 of 150 while judged instances of a canon score 0.68-0.71 - the write-path hint's own floor asks the same question of the same documents at 0.68. The arm now uses that floor, scans 8 hits instead of 3 (a true instance ranked 4th behind snippets of other language families), and the proposer version bumps to 5 so rows examined under the old floor are read again.

bvandeusenandClaude Opus 5	a875a1b2ee	fix(shapes): a semantic miss is not evidence — the divergence check stops reading it (#4208) ... Measured live: true instances of the service-unit canon score 0.68-0.71 against it at best, helpers 0.66-0.75 against unrelated snippets, and nothing reaches the 0.8 floor. The "conclusive miss" fired for nearly every body and silenced real divergences exactly as it silenced helpers. The stored miss basis, its flag withdrawal and the report plumbing are removed; the floor stays at 0.8 and the new-shapes-first ordering stays. False prompts are answered by judgment (exempt with a reason).
