build_rescan's _FIRST_REFUSAL_RE only matched 'no admissible candidate for
...' and required the quote at end-of-string. PR #359 added the
'recognizer matched but produced no injection ... (category=X)' shape, so
extraction returned None and manufactured spurious shifts. Extend the regex
to both shapes and tolerate the trailing (category=...).
With extraction fixed, the live reader legitimately diverges from the v3
baseline on 10 cases (was 2 at the S.4 cut): 5 more first-refusals shifted
one sentence deeper (0019/0023/0025/0027/0047 — overrides added) and 3
refusals became correct admissions (0003/0021/0024 — the +3 that moved
serving 3->6). wrong stays 0; no admission lost. Tests retargeted to the
live counts and artifacts regenerated.
Follow-up: the v4 tests re-run the live reader, so they will drift again on
the next advance; a frozen v5 snapshot (or artifact-derived expectations)
would decouple them.
