Snapshot of every non-log artifact under audit-runs/ from audits 003 through 058: findings.md per audit, comparison CSVs, probe diffs, schema docs, register-dump txts, lr-trace JSONL streams, the saved canary patch diffs, etc. ~284 files / ~52 MB total. Excluded (per .gitignore): probe stdout/stderr/log streams (the raw firehose), guest-memory dumps under audit-026/027/029 (4.5 GB of .bin files; *.bin pattern added to .gitignore this commit). Also adds the orphan audit-058-sub825070F0-activation directory that a subagent accidentally created at project-root instead of under xenia-rs/audit-runs/; relocated to its proper home. Purpose: cross-machine continuity. With these summaries committed, a fresh clone gives the next session the full per-audit context (findings + tables + cascade predictions) without dependence on local-only working tree.

# AUDIT-030 canary-side TRACE-PC-LR captures
|
|
# Build: xenia-canary (Debug Linux x86_64), 30-LOC patch reverted post-session.
|
|
# Patch: src/xenia/cpu/{cpu_flags.{cc,h},backend/x64/x64_emitter.cc,ppc/ppc_hir_builder.cc}.
|
|
# Mechanism: --log_lr_on_pc=N emits HIR Trap(100) on each PC=N exec; trap calls
|
|
# host TrapLogLR(raw_ctx) which XELOGI's PPCContext.lr + r3..r6, r31.
|
|
|
|
# ---- Run A: --log_lr_on_pc=0x824D2C08 (sub_824D2C08, audio init) ----
|
|
# Wall: 22 s, --disable_instruction_infocache=true, --log_level=3.
|
|
# 1 emit message, 1 capture (entry hit during audio init):

# Reading: caller is sub_824D2D14-area at lr=0x824D3054. r3 is host pointer
|
|
# (0xBE62...) into audio_system v80 memory. r4..r6 are init args.
|
|
|
|
# ---- Run B: --log_lr_on_pc=0x824D23B0 (sub_824D23B0, alleged per-frame entry) ----
|
|
# Wall: 2+ minutes (multiple attempts), --disable_instruction_infocache=true.

# 0 emit messages, 0 captures EVER, even after 21,399 KeReleaseSemaphore(0x828A3230)
|
|
# calls + VdSwap=1 in the *first* 2-min run (audio worker active, frame rendered).
|
|
# Second 2-min run got stuck at boot due to slow JIT warm-up post-rebuild
|
|
# (1190-1240 lines log only). 5-min run also stuck.
|
|
# 0/N captures => sub_824D23B0 (PC 0x824D23B0..0x824D2877) is NEVER ENTERED in canary

# during the title-menu loop.
|
|
|
|
# ---- Verification: --break_on_instruction=0x824D2C08 ----
|
|
# SIGTRAP (exit 133) at audio init => break-on-instruction mechanism is live.
|
|
# ---- Verification: --break_on_instruction=0x824D23B0 ----
|
|
# Process ALIVE for 25 s with audio worker firing => no SIGTRAP =>
|
|
# sub_824D23B0 entry not reached, consistent with Run B.
