c58196b795
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.

# Launch Xenia Canary with the settings this title actually needs.
|
|
#
|
|
# Four of these are not preferences — they are measured requirements, and every
|
|
# one of them cost a debugging session before it was pinned down:
|
|
#
|
|
# --apu=sdl + SDL_AUDIODRIVER=dummy
|
|
# There is no PulseAudio here, so `--apu=nop` looks like the safe muted
|
|
# choice. It is not: the log then fills with "CreateDriver failed for
|
|
# index=0", the guest never gets past the intro movie, and the window
|
|
# stays black for 8+ minutes. The SDL driver against a dummy device is
|
|
# both silent AND lets the title advance.
|
|
#
|
|
# NO --audio flag
|
|
# The RE notes say "--audio --apu=sdl". `--audio` is NOT a cvar in this
|
|
# tree, and an unknown argument is not a friendly error: xenia calls
|
|
# ShowSimpleMessageBox from ParseLaunchArguments, BEFORE logging is
|
|
# initialised, and that SDL dialog blocks on XIfEvent forever. Headless,
|
|
# the symptom is a 10x10 window, an empty log, and no guest memory —
|
|
# which reads like a hang deep in the emulator rather than a typo.
|
|
# If this ever appears to hang at startup, suspect a bad flag first.
|
|
#
|
|
# --hid=file --pad_file=...
|
|
# The old vgamepad path made its device through /dev/uinput, which is NOT
|
|
# namespaced — a pad created inside a container registers with the HOST's
|
|
# input stack and every scripted press leaks to the user's desktop. This
|
|
# driver reads a text file instead. Drive it with tools/re-capture/pad.py.
|
|
# Trap worth remembering: 360 menus poll XamInputGetKeystrokeEx, not
|
|
# GetState, so a stubbed GetKeystroke looks like a completely dead pad.
|
|
#
|
|
# one instance at a time

|
# Two emulators (or ours + canary) at once perturbs both and the box.

# Enforced with a lockfile rather than left to discipline.
