notes: build-canary points at a source root that does not exist here
Recorded as a blocker rather than worked around, because it changes what the
next session can plan.
The faithful-capture route is an internal tap at SDLAudioDriver::SubmitFrame,
which receives exactly frame_size_ bytes of the guest s own frame in guest order
with no wall clock in the loop. A cvar-gated WAV writer there would record what
the guest PRODUCED rather than what a device CONSUMED, so it would be gap-free
however slowly the emulator runs -- which is precisely the defect that made both
ADV captures unusable.
The change is small. The build is not. build-canary builds
${PROJECT_DIR:-/work}/xenia-canary, which does not exist in this container; the
source is at /canary. The warm 235 MB tree at /sylph-home/re/canary-build is
configured with CMAKE_HOME_DIRECTORY=/work/xenia-canary, also missing, and its
build-Release.ninja carries no per-file rules -- it re-runs CMake first, and that
reconfigure fails on the absent root. So any Canary change is a full reconfigure
against /canary plus a full compile, at SYLPH_JOBS=4 on a box sitting at about
700 MB free with a documented history of full-parallel builds OOM-killing the
host.
Not attempted: that is a whole session s risk for one probe, and the next session
should decide with the cost in front of it rather than discover it halfway
through.

notes: run-canary is silent TWICE over, and the 6-channel stream is a red herring
Completes an entry committed an hour ago that was incomplete, which is worse than absent because it looked authoritative. Fixing SDL_AUDIODRIVER alone still records silence: run-canary also passes --mute=true on its own command line (line 98). With the driver fixed and the mute left alone, Canary attaches a healthy 6-channel stream, holds it at 100 percent volume, reports Corked: no, and emits nothing. Both layers have to go, and "$@" is last so --mute=false on the caller s side wins. Also records that parec defaults to stereo/44.1 kHz and will resample a 6-channel monitor without saying so -- the first successful-looking capture came back 2ch 44100 from a 6ch sink. And a red herring I nearly published as a finding. pactl shows Canary s stream as float32le 6ch 48000Hz with a full 5.1 channel map, which reads as the guest requesting 5.1 and would have been strong support for the hypothesis that a voice cue s three streams are 5.1 channel pairs. It is not evidence about the game at all: AudioDriver::kFrameChannelsDefault is a hardcoded 6, and the code path actually used, SDLAudioSystem::CreateDriver(index, semaphore, &driver), constructs SDLAudioDriver(semaphore) taking every default. The format is Xenia s; only the content of those six channels is the guest s. That is the same failure this corpus recorded in METHOD earlier today -- the specific observation and the general rule reading identically -- caught this time before it was written down rather than after.

notes: run-canary is silent by default, which records perfect silence
Both of these cost time in one session and both are the kind that look like
success.
run-canary line 82 is SDL_AUDIODRIVER=${SDL_AUDIODRIVER:-dummy}, and its own
header explains why: --apu=nop stalls the guest in the intro movie, so the SDL
driver against a dummy device is what lets the title advance. But the comment s
premise -- "there is no PulseAudio here" -- stopped being true when
tools/audio-capture landed, since that starts a daemon on demand. So a capture
through the null sink records pure silence, of the right length, behind a run
that looks perfectly healthy. The override is
PULSE_SINK=cap SDL_AUDIODRIVER=pulseaudio run-canary, and the live check is
pactl list sink-inputs: empty means Canary never attached and the sink sits at
IDLE. audio-capture s own -inf peak warning is the backstop, but it only fires
after the whole run.
Separately, pkill -f and pgrep -f match the caller s OWN command line. Hit twice
here: pkill -9 -f adv_audio_cap.sh killed the shell running it, and an
until ! pgrep -f "probe.py --run" loop never exited because the loop s own
command line contained the pattern -- which looks exactly like the job hanging.
Kill by process name with ps -o pid= -C instead.

decoder: tell it about the reference assets, and that the DB can be wrong
Some checks failed
The mounts landed but the agent could not learn of them: I documented them in CONTAINER-NOTES.md, which the decoder's prompt does not list, and then restarted the container -- so a fresh session with no memory of the exchange had a 586 MB database and a decompressed image sitting unmentioned in its filesystem. Now in the PROMPT itself, not only in a document, because the prompt is the one thing a new session is guaranteed to read. CONTAINER-NOTES.md is also added to its reading list. And the caveat that matters more than the asset. The .pe is PRIMARY -- the bytes the console executed. The database is somebody's ANALYSIS of them, produced by a disassembler that had to guess, and it is wrong in the ways disassemblers are wrong: misdecoded mnemonics where data was read as code, function boundaries short or long or merged or split, coverage missing entirely for code reached only by indirect dispatch, and names that are derived rather than symbols. So a finding resting on a database row is not established until the bytes agree: read the same address out of the .pe and check. Where they disagree the image wins, and the disagreement is itself worth recording, because it tells the next reader which parts of the database to distrust. A fast index into 9.2 MB of machine code, not a source of truth. |

decoder: mount the disassembly DB and the flat VA image
Some checks failed
The decoder had neither, and reported the gap precisely: four scripts in this repo READ /work/xenia-rs/sylpheed.db and nothing produces it, so the whole static PPC route was consumers with the producer missing. Both exist on the host and are now mounted read-only: the 586 MB database (25 481 functions, 851 classes with RTTI, EH tables, imports, 1.8M indirect-dispatch candidates) and the decompressed image. The image is the more useful of the two. It is a FLAT VA DUMP -- file offset = VA - 0x82000000 -- so reading a known address needs no XEX decrypt, no LZX, and no booted emulator. The decoder had independently recovered the same bytes by dumping /dev/shm/xenia_memory_* and validating against the GamePart table, which is good work and a sound method, but it noted itself that needing a running emulator is a bad dependency for something the entire static corpus rests on. It does not need one. Also recorded that an earlier claim the .pe was STALE was tested and refuted, so nobody re-litigates it, and that instructions.raw is an INT rather than hex. Written down as reference material, explicitly NOT a deliverable: they are read-only, they come from outside the repository, and a fresh checkout elsewhere has neither. Reimplementing the producer belongs in sylpheed-formats, and until it exists every static finding rests on an artefact this project cannot rebuild. |

agents: merge main at the start of every iteration
Some checks failed
Both agents read the protocol, their mission and the shared tooling from their OWN checkout, and both work on topic branches -- so without an explicit sync they follow whichever version of the rules existed when the branch started. Found concretely: tools/audio-capture and two protocol revisions were on main while the decoder worked for hours from a branch that had neither. The port had merged on its own initiative and did have them, which is exactly the kind of divergence nobody notices until the two disagree about what the rules say. |

agents: they never spoke, the decoder lost the disc, and both shared one state dir
Some checks failed
Three defects, all mine, found by checking instead of assuming. **They never exchanged a word.** SendMessage=0, ListAgents=0 across both new sessions. PROTOCOL.md specified in detail what a message MAY and MAY NOT do and never said how to send one or that the other agent was addressable -- they knew that last time only because the human told them directly, and rebuilding with fresh volumes wiped it. Policy without mechanism is prose. Now documented with the two addresses, a worked example, and an instruction to introduce themselves on the first iteration rather than waiting to have a question. **The decoder lost the disc and the ISO.** They used to arrive inside the project mount and silently stopped when /work became a clone. Silently is the word: the disc-gated tests SELF-SKIP without SYLPHEED_DISC and report green, so a whole test suite would have passed while measuring nothing. Both are now mounted explicitly, the ISO at a stable path so run-canary does not depend on host directory names. **Both agents shared one Claude state directory.** They share the host's ~/.claude, and once both working directories became /work they resolved to the same projects/-work/ -- two supposedly independent agents writing to one place, which undoes the point of separate checkouts. Each now has its own volume, seeded once from the host with credentials only, so a token refresh writes locally and neither can corrupt the host's auth. Also widened the pacing rule. It banned ScheduleWakeup by name; the decoder then scheduled itself an hourly cron job -- not harmful, but the same instinct that ended a run yesterday, through a door I had left open. Now: no self-scheduling by any route. Mount audit after the changes: shared and intentional are the exchange volume and the read-only credential seed. Everything else -- repo, Claude state, cargo, target, canary, disc, ISO -- is per agent or one-sided. |

containers: each agent clones the monorepo into its own volume
Some checks failed
The last structural fix for the collision class that has bitten three times. Both containers now clone the repository into their OWN named volume instead of bind-mounting a human's working tree, so an agent's local git config cannot capture a human's commits, a credential helper cannot leak a container-only path onto the host, and a `git add -A` cannot sweep another party's in-flight files. Cloned once at startup and never auto-pulled: pulling under a running agent moves files out from under whatever it is mid-edit, which is the same bug again. Accepted knowingly: Claude Code keys per-project memory off the working directory, so moving off the host path starts that memory empty. The corpus in docs/ is the memory that matters and it travels with the clone. Other changes: * docker/agent -> docker/decoder; the launcher is sylph-decoder. Roles, not "the agent", now that there is more than one. * /reborn is gone -- one repository now, so the port reads HANDOFF from its own checkout rather than through a live read-only mount of someone else's tree. * Canary mounts separately at /canary; it stays a fork tracking upstream. * A shared `sylpheed-exchange` volume at /exchange, with tools/ on PATH so `share` is available in both. * The decoder's credential file gets the .host-copy treatment the port already had -- `credential.helper=store` rewrites by rename-over-target, which is EBUSY on a bind mount and reports a fatal that is not one. * Budget split deliberately: decoder 5 cpu / 6 GB, port 3 / 4, leaving room for the planned Referee. "Half the host" was right when there was one agent. Prompts move to docs/agents/ and are rewritten around the protocol: the oracle is the running game, dynamic RE stays with the decoder, each iteration must attempt to refute one claim of the other, and neither may verify its way out of its own role. |

agents: the team protocol, the share tool, and a player's-eye navigation doc
Some checks failed
**navigation.md rewritten from the player's chair.** It was written from the inside out -- GamePart ids, pak names, sprite names -- which is how WE find things, not what the game shows anyone. Now it describes what is on screen, what you press and what happens, with internals as footnotes. Most rows are open on purpose: it exists to be filled in by playing, and the in-game tutorials are the resource for the flight half. **tools/share** gives transient files provenance without giving them history. Three kinds of thing were travelling down one channel with opposite needs: code and decoded knowledge want permanence, cited evidence wants permanence, and "look at this PNG" wants no history at all. The third kind bloats a repository forever; passing it by message is worse, because the receiver gets bytes with no idea which build produced them. `share put` records who, when, what, the sender's commit, and whether their tree was dirty -- because a capture taken from a modified tree cannot be reproduced from the sha, and the receiver deserves to know that before building an argument on it. **docs/agents/PROTOCOL.md** is the contract. The parts that matter: Dynamic RE stays with the Decoder -- most of what is open is behavioural and cannot be answered from the file. What the planned Referee adds is different: bias enters at what you CHOOSE to capture, so a corpus captured to a fixed protocol by someone with no hypothesis is worth more than one captured to settle an argument. A message may point, ask, prioritise and challenge. It may not change scope, redefine ground truth, or carry a finding instead of writing it down -- including a message claiming to relay the human, because a relayed instruction has no evidence attached and this project has watched a wrong belief travel further and faster than its correction. Adversarial duty is explicit: every iteration, try to refute one claim of another agent and record the attempt either way. Run your own instrument through a control first. Disagreements go to the human with both positions, not to whoever is more certain. And no agent may verify its way out of its own role: the Port has no oracle, the Decoder builds nothing, the Referee interprets nothing. |
