Takes the port branch up to77320d5e-- the state the human play-tested on 2026-09-02 -- for SOURCE paths only. Not a branch merge: `auto/port-p6-audio` is 366 commits and 938 files, and most of that must not land. WHAT COMES IN (76 files, all human-confirmed working): * the logo splash animation.08ed3dd1found it: `pose_at` ASSIGNED the settle instant instead of clamping to it, so the splash never animated at all -- and the same bug manufactured a passing harness result, because the harness photographed t past the settle. Confirmed by play-test: "cannot notice any obvious difference from the actual game." * gamepad input -- (A)/(B) bound additively (`ui_accept` ships with NO joypad binding), stick latched with hysteresis at the game's own 61% digitise threshold. This is what made (A), video-skip and Extras work at all. * menu navigation and flow, menu audio, the exporter, the authored declarations, and 23 verification tools under tools/port/. WHAT IS DELIBERATELY LEFT ON THE BRANCH: * everything afterc0ae460a-- the F5/F6 title-timing investigation, whose own tip commit calls itself a "hand-off for one-minute human checks". Unchecked by definition; it goes through the new review gate like anything else. * the OPTIONS menu work of 2026-09-03. Real, probably good, NOT play-tested. * the F1 repeat mechanism, which its own commit calls "deliberately inert". WHAT MUST NOT LAND, AND WHY THE .gitignore CHANGED: 545 MB of extracted game content was committed on that branch -- 850 sprite, audio and transcoded video files under `export-probe/` and `export-probe2/`, plus 246 MB of loose .wav and .tsv at the repo root. This repository's own rule, in this file, is "never game content". The rule was not missing. It was written, and it was tightened on that very branch, with a careful comment explaining why BOTH `export/` and `data/base/` had to be listed -- while the exporter was writing to a third name that nobody had thought to list. Enumerating names is the thing that failed. So the ignore rules now describe the SHAPE: any top-level `export*/`, game media by extension, and loose capture output at the root. Verified both ways -- it catches all four offenders and ignores nothing currently tracked. Verified: `cargo check --workspace` clean; all nine GDScript files parse in project context, with a positive control (an injected syntax error is detected, 3 lines) so the clean result means something. `tools/port/check-all` was NOT run -- it needs the container, the export tree and a display.

# Remove driver-inserted silence from a capture, exactly.

# tools/port/strip-padding in.wav out.wav

#
|
|
# WHEN THIS IS VALID, AND WHEN IT IS VANDALISM. The distinction is the whole
|
|
# tool and getting it backwards destroys the artefact:
|
|
#
|
|
# * PulseAudio's monitor SUBSTITUTES silence. It advances on a wall clock and
|
|
# replaces audio that existed when the producer was late. Information is
|
|
# gone; deleting the holes compresses time unevenly and repairs nothing.
|
|
# DO NOT RUN THIS ON A MONITOR CAPTURE.
|
|
# * Xenia's ALSA writer PADS. It inserts silence between samples the guest
|
|
# emitted when its ring is empty (`alsa_audio_driver.cc:359`). Nothing is
|
|
# lost and nothing is overwritten, so removing the padding is EXACT -- it
|
|
# hands back the contiguous stream the guest produced.
|
|
#
|
|
# CONTROLLED, not argued. A real music+SFX bed (137.37 s, with 454 zero runs of
|
|
# its own) had 1 149 holes inserted at 8.37/s to +9.9 % length, matching the
|
|
# observed ALSA profile, then was stripped:
|
|
#
|
|
# original vs itself r 1.000 lag 0.0 s margin +0.141 [ceiling]
|
|
# PADDED vs original r 0.436 lag -12.2 s margin +0.006 [destroyed]
|
|
# STRIPPED vs original r 1.000 lag 0.0 s margin +0.142 [recovered]
|
|
#
|
|
# Frame counts: original 6 593 984, stripped 6 559 880, and the original stripped
|
|
# of its own genuine zero runs 6 560 044 -- a difference of 164 frames, 3.4 ms in
|
|
# 137 s, from inserted holes abutting genuine ones and merging.
|
|
#
|
|
# ⚠️ It removes GENUINE silence too, and cannot tell the two apart -- that is why
|
|
# the reference above is the unstripped original: recovery does not depend on
|
|
# stripping both sides. On this material the genuine runs total 0.71 s in 137 s
|
|
# and cost nothing measurable. On material that is mostly silence they would.
