nethersx2-turnip-classic documents the shim rules of the revision it
pins, and says so in prose: the classic build is that revision. Compared
to HEAD it reported the same two changes every pass, and recaling would
have repointed its refs at rules this build never had.
pin_frozen says the freeze is deliberate, and the profile is then judged
against its own revision, exactly as one pinned to a superseded tag
already was. Recale and bump are refused for it, which is what makes the
declaration safe to trust.
A recale rewrites the located tokens and leaves the sentence alone, so a
prose run keeps `a.c:228, 1439-1443` while the rendered form drops the
space. Comparing the two literally made a run that had just been written
look unwritten, pending_recale counted it, and bump_commit refused for
ever.
mariani was held back by three of them: it recaled twenty-five refs and
could never advance its pin, which is the desync the all-or-nothing rule
forbids. 67 refs, all anchored.
openbor.c is 55k lines at the pin and 57k at HEAD, over a ceiling of
40k, so its ref reported CHANGED with nothing to act on: the mapping was
never attempted. Diffing that pair takes nine seconds, and the fallback
only runs once exact anchoring has failed, which is rare.
The ceiling now sits above it and still stops a pathological pair from
stalling a sweep of every profile. savesettings moved from 2675 to 2940
and the range maps cleanly.
The diagnostic caught a ref whose file was missing at the pin. nestopia
showed the other shape: the file is there and the line is not yet. Its
palette and database loads were cited at 2041 and 2063, which is where
HEAD carries them, against a pin four hundred lines shorter, and that
reported as a plain GONE with nothing to act on.
A cited line past the end of the pinned file that fits HEAD is the same
finding as before and now says so. nestopia's pin moved to the revision
its refs describe: 8 refs, all anchored.
