`cargo fmt --all -- --check` has failed on every run in this repository's
history, identically on `main` and on every branch. This is #12.
Mechanical: `cargo fmt --all`, nothing else. 154 files, all `.rs`, no other
extension touched. `cargo check --workspace` exits 0 afterwards, so nothing
changed semantically.
ON THE ORDERING, WHICH WAS THE REAL QUESTION.
HANDOFF-2026-09-06 section 7 warns this is the expensive fix: a whole-tree
reformat before #7 and #8 return "would put a conflict in every file of 861
commits and make the reviews those items exist to enable unreadable".
That is measurably too pessimistic, and it had been reasoned rather than
tested. Measured here by three-way merging a rustfmt'd `main` against both
unmerged branches, file by file:
file/branch pairs tested 32
merges CLEAN 28
merges CONFLICTING 4 (8 conflict hunks total)
sylpheed-cli/src/main.rs 1 hunk
sylpheed-export/src/check.rs 1
sylpheed-export/src/screen.rs 4
sylpheed-export/src/video.rs 2
All four are against `auto/frame-blend-draw-path` only;
`auto/port-p6-audio` does not conflict anywhere. The earlier framing --
154 dirty files, 133 that cannot collide, 21 that can, the collision set
carrying 147 of 774 hunks (19%) -- reproduces exactly. What it did not say
is that most of the 21 still merge cleanly, because rustfmt's edits and the
branches' edits rarely land on the same lines.
So the cost of sweeping now is 4 files and 8 hunks for one branch, against
a check that is otherwise red forever. Deliberately NOT folded into the
WASM PR: 154 reformatted files would make that one unreviewable.
Closes#12
Two things settled, one of them a correction of my own claim from the last
iteration.
The cue unit is verified rather than assumed. parse_timing computes mm*60+ss,
but only if the token really is mm:ss.cc, so I checked against an independent
oracle: the movies are on the disc and a cue must land inside its own movie.
66 English movies with subtitle tracks, 0 cues land after the movie ends.
Centiseconds would have overflowed essentially all 66. The seconds reading
stands and the verdicts built on it survive.
"The sample rate does not converge" does not. I reported implied rates of
39742 / 20563 / 23108 Hz as irreconcilable. They are not estimates of the
same quantity -- each is a ONE-SIDED BOUND. The audio must be at least as
long as the last cue, so samples/cue is an UPPER bound; it cannot outlast its
movie, so samples/movie is a LOWER bound. Intersecting:
bank samples cue movie lower Hz upper Hz
VOICE_D_450 158967 4.00 9.30 17091 39742
VOICE_D_451 76084 3.70 9.30 8180 20563
VOICE_D_453 108608 4.70 9.30 11677 23108
=> 17091-20563 Hz, non-empty. A single rate IS consistent.
I had been comparing them as competing point estimates, which is why they
looked contradictory.
What is still open, and stated as such: that window contains no standard XMA
rate. The lower bound assumes a whole bank plays inside one movie, and each of
these banks is bound to 3-5 movie slots -- so if a bank holds several takes
the lower bound is void, leaving rate <= 20563, which 22050 nearly meets.
Next step recorded: establish whether a shared bank is one line or several.
