Some checks failed
The audio work was three parts and I shipped two. The transcode-fidelity method and the pinned 5.1 downmix landed; the null sink -- the only one that answers "what does the GAME play" -- I deferred to "the next natural rebuild window" and then rebuilt both images four times without doing it. pulseaudio-utils is now in both, with tools/audio-capture wrapping it: a null sink is a real device as far as an application is concerned, so Canary and Godot open it normally and parec records what they emit. This unblocks the decoder's Q8. The cue-to-event bindings are currently a name match against the authors' own identifiers -- a plausible guess, not a measurement -- and capturing what the game plays on a menu move converts them. `audio-capture run` reports the peak level and warns when the capture is silent, because silence is the failure that looks like success: a WAV of exactly the right duration, full of zeroes, because the application opened a different sink. A duration check alone passes it, which is how a confident wrong number gets made.

# Autonomous port agent for the Sylpheed Godot menu shell.

# DELIBERATELY SMALL. The reverse-engineering container next door is 4.36 GB

|
# because it builds Xenia Canary and drives it under a software Vulkan stack.
|
|
# This agent has no emulator, no oracle and no C++ build: it converts already-
|
|
# decoded assets and drives Godot. Keeping it light is what lets both containers
|
|
# run on one 12-core / 15 GB box without the memory pressure that has crashed it.
|
|
#
|
|
# What it needs, and nothing else: Rust (the exporter), Godot 4 (the runtime),
|
|
# ffmpeg (the transcode), and a headless display to screenshot Godot for
|
|
# comparison against the reference renderer.
