The late start was a second condition on the start filter, end - s < 1_500_000,
only within one bank. ADV's predecessor trailer sits 3618816 B before end, so it
was rejected and start fell back to anchor, a TOC offset rather than a stream
boundary -- which is why it hit regions over 1.5 MB and never single-stream ones.
ADV region 3114352 -> 3618816 B, streams 2 of 3 -> 3 of 3, complete, dropping
zero chunks. S00A 1 of 3 -> 2 of 3 with the third digitally silent. The runtime
no longer prints an incomplete line for either.
Also fixes the warning crying wolf: S00A still read KNOWN INCOMPLETE over a
93.694 s stream of exact zeroes. Exported gains content_waves and the warning,
console line and manifest field all key on kept < content rather than kept <
present. Second time in two iterations this warning was wrong in the cautious
direction -- over-warning is what makes the next real warning unreadable.
S00A is a second movie in the predicted direction: kept went 1 -> 2 because a
chunk that was a different duration now matches at 93.694 s. Not independent
ground truth, but a different asset and the outcome was predicted first.

FOUR THINGS, and the first is what MISSION section 3 calls the measure of
progress.
DELETED `exit_ramp_units` AND `exit_ramp_seconds`. They were authored because the
disc had no time slot on a group's final keyframe, so the ramp into it was the
one unknown duration per screen. Under the corrected record layout that keyframe
does not exist -- a group is an 8-byte header then frames x {u32 time; 36-byte
pose} and every pose is timed. VERIFIED DEAD BEFORE DELETING: setting it to 9999
(166 s) moved the boot's transitions by 0.04 s, which is wall-clock jitter, and
both uses in ScreenView are gated on a condition that no longer fires on any of
the export's 866 keyframes.
INVERTED THE FORMAT'S OWN RULE. `check.rs` enforced "the final keyframe has no
`t`; the disc has no time slot there" and FORMAT.md stated it. Both are now
backwards, and the validator fired 150 times on a re-export. I had not run
`check` between pinning the tag and measuring against the oracle -- the pixel
harness was green while the format validator was failing on every screen with a
multi-keyframe group. A correctness harness does not replace a format one; they
fail at different layers.
GUARDED A SCALE-0 LEAF, which the Decoder hit in its own renderer: its leaf
branch marked the element drawn unconditionally while the blit returned early on
zero scale, so a scale-0 leaf suppressed its parent and blanked the element --
live on all four loading screens. This port did not have the bug only because
authored/rendering.json happens not to list pgloading_loop5. That is an accident
of a gate written for another reason, not a defence, so `_draw_leaf` now reports
whether it drew and `_draw` falls back to the parent.
ISOLATED THE PACING QUESTION rather than leaving it as a suspected regression.
Legacy association: publisher 4.70 agrees, developer 3.92 DIFFERS. Corrected:
publisher 4.26 DIFFERS, developer 3.62 agrees. Both misses are ~0.03 s outside a
composite bound. The association traded which screen is marginally out; it did
not regress the pacing.
Bumped the pin c -> d for the parser and audio changes. Its headline renderer
change does not reach this port: sylpheed-cli builds from the workspace crate.

I tested the wrong switch. SYLPHEED_KF_TIME_SHIFT is a superseded partial fix: it
got the association right but LEFT POSE 0 UNTIMED, which is exactly why the
untimed keyframe appeared to move from last to first. The real correction is the
DEFAULT in the tagged crate, with the old reading behind SYLPHEED_KF_TIME_LEGACY.
So last iteration's five rows measured a mismatch against a knob nobody should
use -- I suspected they were not decisive, I did not suspect the knob was retired.
THE CONSEQUENCE IS MUCH SMALLER THAN I BUDGETED. A placement group is an 8-byte
header then frames x {u32 time; 36-byte pose}, so pose 0's time is the group's
lead-in word and every pose is timed. Measured on the re-export: 866 keyframes,
0 untimed. `pose_at`'s "the final keyframe carries no t, so give it a synthetic
time" premise does not invert, it DISAPPEARS -- dead code rather than wrong code,
which is why nothing needed re-deriving. And the leaf now reads t=0 x=-639,
t=150 x=-39, t=540 x=1521, giving x=781 at t=355: the Decoder's predicted
top-left, and the 1300 px discrepancy is gone.
Pinned by tag, which is what MISSION section 2's tagging rule is for. BLOCKED was
wrong in both directions -- "cannot be taken yet" AND "only when that branch lands
on main". It arrives when the tag is pinned.
COST STATED: sylpheed-cli builds from the workspace crate, so until this reaches
main the exporter and the reference renderer read different decoders and
verify-screen compares two eras. verify-capture is unaffected -- it compares
against oracle captures and never touches the CLI. Revert to the path dependency
when the tag is an ancestor of main.
Oracle: publisher_logo 1.00% -> 0.75%, developer_logos 0.39% -> 0.33%, and
extras' differing region COLLAPSING from 736x525 to 398x295 at the sweep position
-- the residual localised onto the one element still in question. title unchanged
at 1.82%, now posed at t=355, the Decoder's FITTED sweep time. t=390 measures
1.65% and picking it would be fitting the pose to the score.
REFUTED, MINE: "ptlogo_eff2 is the single drawn element at a scale that is not a
whole multiple of 100%". That census was parents-only; the 45 leaves hold
thirteen distinct non-whole-multiple scales and 125% is among the rarest at two.
The claim's real content was "the only one the port draws" -- about my element
set, not the disc.

The crate is in the workspace and builds, but its lock entry was never
committed -- `build-export` regenerates it on every fresh container, so it
only shows up as a dirty tree nobody caused.

The movie cutscene subtitle + voice pipeline, driven by the ADVERTISE_MOVIE
manifest (the authoritative movie -> subtitle -> voice index). Also flushes
several sessions of local WIP (async viewer loading, grouped-pool XBG7/hero-ship
decode, drawlog tooling). See docs/HANDOFF-movie-voice-subtitles-2026-07-19.md.
Subtitles (movie_subtitle.rs):
- Full movie->track->text chain; join multi-line captions sharing one timing
(fixes S13A dropped "Look at it father" line); overlap-safe active_cues();
Latin-1 accents preserved.
Voice (slb.rs): XACT .slb -> XMA1 RIFF; take the FIRST sub-wave bounded by its
declared data size (fixes S10-S16 alternate-take garble); list_voice_clips.
Manifest (movie_manifest.rs): parse ADVERTISE_MOVIE (0x5B983A08) for the real
movie->voice binding (not always VOICE_<movie>; e.g. hokyu -> VOICE_D_* in etc\).
Resolve the token's sound.pak path via sounds.tbl. DIRECT bindings only — the
demo-id shared-clip fallback for unbound hokyu movies was verified WRONG in-game
and reverted (unbound hokyu stay unvoiced; correct join key is an OPEN problem).
Viewer: manifest-driven voice (movie player toggle + solo button), standalone
"Voice Lines" browser, stacked caption overlay.
Tests: 46 formats-lib + 11 viewer-lib + movie_manifest/movie_subtitle/slb disc
tests; full workspace green.

Decode and present four more PAK item types in the pack browser's detail
pane. All content is decoded off-thread in build_pak_rows and attached to
each PakRow, then rendered with egui's own texture facilities — the Bevy
texture pipeline and egui's global font system are untouched.
formats crate (Bevy-free, reusable by CLI):
- ixud: parse IXUD localized-string tables as subtitle cue lists (UTF-16BE
pool, SUBTITLE header + (text, timecode) pairs -> Vec<Cue{start,end,text}>).
- font: OTF/TTF/ttcf metadata (family / faces / glyphs) via ttf-parser.
viewer:
- PakRow gains `content: PakContent` (Subtitle | Font | Png | Text | None);
classify_content fills it for IXUD / fonts / PNG / xml+text within the
existing decode budget. Font samples are pre-rasterized off-thread with
ab_glyph into an image (ImageRgba) — ab_glyph returns Option/Result at every
step, so a bad font yields no sample instead of panicking (the earlier
egui set_fonts approach crashed the app on atlas rebuild).
- draw_pak_browser dispatches on content: subtitle cue table, font metadata +
sample image, PNG image, scrollable text; else the existing IDXD detail.
Borrow-split PakView instead of cloning the (now heavy) rows each frame;
one hash-keyed egui texture cache serves both PNG and font-sample images.
Subtitle<->movie auto-matching is deferred: movie filenames don't hash to the
IXUD keys and no cross-reference table was found (the link is an internal
MSG_DEMO id), so the movie player gets no subtitle track yet.
Tests: ixud unit tests; disc tests for the real English subtitle track
(cues + timecodes), eng/deu localization, font metadata, and off-thread
rasterization of the real font.

Add an in-explorer video player for the dat/movie/*.wmv cutscenes.
Decode via the ffmpeg/ffprobe CLI (no libav linking): video streams from an
`ffmpeg -f rawvideo -pix_fmt rgba` pipe read into fixed w*h*4 frame chunks over
a bounded channel (paused/behind => ffmpeg back-pressures on its pipe); one
reused Image is overwritten in place each tick. Audio is best-effort: the track
is pre-decoded to a temp stereo WAV and played through a rodio Sink (volume /
play / pause / seek-via-skip_duration for free). Native-only under
cfg(not(wasm32)); VideoPreview registers unconditionally so the UI compiles for
wasm. Mirrors the .pak load pipeline (FileSelected -> bg thread ->
IsoLoaderMsg::VideoLoaded -> apply_loaded_video -> advance_video_playback), with
a single free_video teardown wired into every other viewer's reset.
Controls:
- play/pause button, click-on-frame toggle, Space / arrow (+-10s) shortcuts
- seekable timeline with mm:ss labels; volume slider (greyed when no audio)
- live scrubbing: a coalescing one-shot `ffmpeg -ss -frames:v 1` grabber always
jumps to the knob's latest position, so dragging shows the frame under the
knob in real time; that grabbed frame also bridges the gap after a commit-seek
so there's no black flash while the streaming decoder catches up.

Reworks the XPR2 texture path after RE against the retail disc (viewer
previews were scrambled/failed).
- de-tile: replace the naive Morton-over-32×32 approximation with the
faithful Xenos Tiled2D bank/pipe/macro-tile address formula (ported
from xenia texture_address.h). Verified correct: the Acheron backdrop
decodes to a sharp planet with its spiral storm.
- endian: undo the X360 word byte-swap per the fetch-constant endianness
field (k8in16/k8in32/k16in32) — without it BCn/ARGB data is noise.
- cubemaps: parse TXCM resources (skybox/backdrops), decoding face 0,
instead of erroring "No TX2D found".
- A8R8G8B8: correct channel order after the k8in32 swap ([A,R,G,B]→RGBA)
— the Acheron backdrop is now correctly green, not red.
- XPR files are texture PACKS; add XPR_RES_INDEX to select a resource.
- CLI `texture export` now writes real PNGs (texpresso BCn decode +
image), replacing the stub. Adds texpresso + image deps.
- tests/texture_disc.rs: integration test running the pipeline over real
disc .xpr files (28/28 parse). RE debug knobs: XPR_NO_DETILE /
XPR_NO_ENDIAN / XPR_FORCE_ENDIAN.
KNOWN ISSUE: mipmapped DXT1 textures still decode to noise — mip 0 is
not at base_address in the multi-resource packs (localized to a mip
storage-offset quirk; uncompressed + de-tile + endian are all verified).
