Version synced across the four locked points (pyproject, __version__, README
badge, README install pin) + CHANGELOG.
Corrections this release carries, both measured rather than reasoned:
- docs/LIMITATIONS.md said the script-tag change removed "the last"
quadratic-backtracking site on the output path. It did not. Corrected, with
the 334.7s gate measurement that falsifies it.
- README's coverage line claimed 126/126 classes; the matrix reports 128/128.
Stale since before v0.3.2. Test badge was 642, actual 666.
New residual recorded (LIMITATIONS, now 30 items, README synced): the sweep
flags on timing above a 1.5ms noise floor at N=8000, so an arm hiding under it
could still cost ~23s at the cap. What this supports is "no arm worse than ~23s",
not "no quadratic arm remains" -- and the blind spot is demonstrated, since a
generic-payload pass found only one of the two patterns.
666 tests green, coverage matrix 128/128 with 6/6 gaps holding, exit 0.
