Investigation probes for the ADV.wmv intro-video deadlock (feeder's demux
source-read 0x825211a0 returns no-data 0x80500000 where canary returns 0).
- xenia-kernel/state.rs: extend AUDIT-DEREF (fire_audit_pc_probe_if_match) to
deep-dump the demux-state object (to +0xfc), its buffer descriptor [sub+4],
the byte-source sub-objects ([sub+0]/[+0x30]/[+0x94] and [src0+0x2c]), and
to WALK the windowed-buffer cached-block linked list (AUDIT-BLK: per-block
64-bit start/size/dataptr) exactly as mapper 0x82522118 does. Read-only,
env-gated (XENIA_AUDIT_DEREF); lockstep digest unaffected.
- xenia-app/main.rs: XENIA_DUMP_SLOTS observe-only scheduler runqueue dump.
- xenia-app/tests/sylpheed_oracles.rs: resolve ISO via SYLPHEED_ISO, then the
repo-root sylpheed.iso symlink, then default; fix path typo.
- .gitignore: exclude .claude/ (71k files / 66GB agent worktrees) and the
local investigation artifacts (audit-runs/, exit-thread-state.json, zq_*.py).
Findings (full chain in handoff notes): all ASF header metadata parses
correctly (packet size 16415, count 4728, 2 streams); cursors correct
(cur=5868, limit=77.6M); the windowed buffer works and slides (512B blocks);
no-data originates deep in the byte-read/parse chain, not from an empty buffer.

audit-out/ and audit-*.md are local report artifacts produced by the
PPCBUG audit pipeline; *.stdout/*.stderr/*.log are stress-harness run
captures. Switch /target/ to target/ so per-crate target dirs (e.g.
crates/xenia-app/target/ used as a stress-output sink) are also ignored.

Rust reimplementation of the xenia Xbox 360 emulator targeting reverse-
engineering and preservation, initially scoped to Project Sylpheed.
Includes:
- XEX2 loader (LZX decompression, AES decryption, PE parsing)
- XISO / XGD2 disc image VFS
- PPC interpreter with 200+ opcodes and VMX128 decoding
- Static analyzer: functions, cross-references, labels, asm + SQLite output
- HLE kernel covering the xboxkrnl/xam subset used by Sylpheed init
- Debugger with in-memory and SQLite-backed execution tracing
- `xenia-rs` CLI with extract/dis/exec commands that produce cumulative,
superset SQLite databases and opt-in instruction/import/branch traces
