Before this commit, `unset SYLPHEED_DISC` did not disable the disc-backed
suites on the machine that has the disc: every `disc_root()` fell back to a
hardcoded absolute path that exists on this box. The env var looked like a
control and was not one. Same for $SYLPHEED_RES3D and $SYLPHEED_ISO.
Replace the duplicated resolvers with one `tests/common/mod.rs`:
- 17 local `disc_root()` definitions -> 1
- 7 copies of the skip macro -> 1 (`skip_without_disc!` and siblings)
- 16 hardcoded absolute paths -> 0 executable ones
(3 of those were inline in `mesh_disc.rs`, in no resolver at all,
and 2 were in `examples/`)
- `corpus_report.rs` now reports on the SAME resolver the suites use,
instead of a second copy of the logic its own comments flagged as a
drift risk.
The 17 copies had already drifted into FIVE variants, and they were not all
the same function. `movie_manifest_disc`, `movie_subtitle_disc` and `slb_disc`
honoured $SYLPHEED_DISC and nothing else, while the other 14 fell back. So one
name already meant two things -- a third instance of the shape #16 is about.
The shared helper adopts the env-only behaviour those three already had, rather
than inventing a sixth variant.
Two module docs still described the fallback after it was deleted, which is the
same defect in prose: `texture_disc` claimed "or the default dev path exists"
and `pak_idxd_disc` said "or drop it at the default dev path below". Both now
say what the code does.
Verified both ways on the machine that HAS the corpus, which is the only place
this refactor can be falsified:
A env unset -> "ABSENT -- $SYLPHEED_DISC unset; its suites self-skip"
suites=31 passed=209 failed=0 ignored=14, slowest 0.12s
B env set -> "PRESENT via $SYLPHEED_DISC" (all three corpora)
suites=31 passed=209 failed=0 ignored=14,
slowest 1235.53s (mesh_consistency_disc)
Identical tallies, opposite corpus states, ~10000x apart in wall clock. (A) is
new behaviour -- it was previously unreachable here. (B) proves nothing broke.
`just test-disc` sources `.env` (already gitignored) for the set case. Note the
quoting trap documented there: the corpus paths contain spaces, and an unquoted
`VAR=a b c` parses as "run command `b`", failing silently into ABSENT -- which
looks exactly like a working skip.
Remedy (1) (`#[ignore]` + `--ignored`) is deliberately NOT done here: (3) already
moves the mode from the filesystem into the environment, and `#[ignore]` already
carries three meanings in this directory (corpus-absent, known-failing, bare).
Overloading it a fourth time would re-create the defect.
`cargo fmt --all --check` clean; no new compiler warnings.
Refs #16
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`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
The 16.16 reading of +0x04 rested on twelve bundles at 30.0. They are not twelve
witnesses: they are TWO bundles - pghud_range_main_em/emeff and
pghud_range_nose_em/emeff, both dur 30 - repeated across six language PAKs. A
30-frame flash is equally consistent with 0.5 s at 60 and 1 s at 30, so the
observation that "30.0 bundles are shorter" says almost nothing.
Worse for the clean fixed-point reading: the four bundles at 0x3C0001 would be
60.0000152 fps, which nobody authors. They are py_ranking_jump/py_ranking_next
dialogs, all dur 60. So the better reading is <rate:16>.<flag:16> - a rate-like
number in the high half and a small low field that is 0 on 2843 bundles and 1 on
four, meaning unknown.
Also stated: nothing in this container can settle it by timing, because the
emulator runs on software Vulkan far from real time - a stopwatch would measure
lavapipe rather than the game.

The rate/duration reading of the bundle header came from the values alone, so it
was checked against something the file states independently: the keyframe `time`
fields in the placement region.
Over the 2313 bundles that have both, the largest keyframe time is <= +0x08 in
EVERY one, none exceeds it, and 444 reach it exactly. The refutation attempt is
in the same data: a large unrelated constant would bound every time too, but the
max_time/+0x08 ratio would then pile up near zero - instead it peaks at exactly
1.0 with 520 bundles. Asserted, including the shape of that histogram, so the
bound cannot later be waved through as vacuous.
Stated precisely because the units are a separate claim: what is proven is that
+0x08 is the animation length in the SAME UNIT as a keyframe's time. That the
unit is frames still rests on the values (30/60/120/1200) and on the 16.16
reading of +0x04, which stays amber - the only new evidence for it is that the
twelve 30.0 bundles cap at +0x08 = 30 while the 2843 60.0 ones reach 1440, and
twelve bundles is not a demonstration.
