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-040 canary patch — extends audit-030 TrapLogLR helper to log
|
|
# r3..r10 + r28..r31 plus a 32-byte memdump from r4 and r5 (the two source
|
|
# pointers passed into sub_8244FC90). Total +56 LOC across 4 files. Applied
|
|
# 2026-05-09 then reverted at session close; `git status` clean afterwards.
|
|
#
|
|
# Files changed:
|
|
# src/xenia/cpu/backend/x64/x64_emitter.cc (+43) TrapLogLR + dump_bytes
|
|
# src/xenia/cpu/cpu_flags.cc (+5) log_lr_on_pc cvar
|
|
# src/xenia/cpu/cpu_flags.h (+2) DECLARE_uint64
|
|
# src/xenia/cpu/ppc/ppc_hir_builder.cc (+6) Trap(100) emit on PC match
|
|
#

|
# Build: cd build/ && ninja -f build-Debug.ninja xenia_canary
|
|

|
|
# The TrapLogLR helper now reads:
|
|
# ctx->r[3..10], ctx->r[28..31], ctx->lr
|
|
# thread_state->memory()->TranslateVirtual<const uint8_t*>(r4) -> 32 bytes
|
|
# thread_state->memory()->TranslateVirtual<const uint8_t*>(r5) -> 32 bytes
|
|
#
|
|
# Output format:
|
|
# TRACE-PC-LR pc=8244FC90 lr=82450440 r3=BC65CD00 r4=701CF580 ... r31=701CF3C0
|
|
# TRACE-PC-LR r4* addr=701CF580 bytes=F800008C 00000000 ... (8 dwords hex)
|
|
# TRACE-PC-LR r5* addr=BC79C960 bytes=820B57D0 FFFFFFFF ... (8 dwords hex)
|
|
#
|
|
# Reusable for other ctor-input investigations: change --log_lr_on_pc value;
|
|
# reinterpret r4*/r5* dumps based on the target function's argument convention.
