Source changes (dormant parity infra, retained from iterate 2.AI/2.AO): - xenia-kernel/exports.rs: nt_create_event manual_reset polarity + related event wiring - xenia-gpu/mmio_region.rs: D1MODE_VBLANK_VLINE_STATUS hardcode parity Also lands the audit-runs/ analysis notes (.md/.txt/.json digests) for the iterate 2.x VSync/0x10e8/0x1004 wedge investigation. Raw trace dumps (.jsonl/.gz/.csv/.stdout) and agent worktrees (.claude/) are gitignored as regenerable local artifacts — see memory + HANDOFF for the running findings.

Phase 4 — Re-validation (XAM audit)
| gate | result |
|---|---|
| 1. cvar-OFF determinism (3 runs) | PASS all 3 = c6d895829b4611964978990ae1cb8a6a (SAME as C+6½ baseline) |
2. Phase B image_canonical_sha256 |
PASS unchanged (no Phase B re-snap needed — no body changes) |
| 3a. Phase A main matched prefix ≥ 102158 | PASS 102158 (unchanged) |
| 3b. Phase A all other tid chains | PASS no regression — see below |
| 4. Both engines build clean | PASS ours: cargo build --release ok (only pre-existing dead-code warning) |
| 5. Unit tests | PASS 146 passed, 0 failed, 0 ignored, 0 measured |
| 6. Hallucination count | N/A — 0 hallucinations found, audit clean |
Gate 1 — determinism
c6d895829b4611964978990ae1cb8a6a digest-cvaroff-1.json
c6d895829b4611964978990ae1cb8a6a digest-cvaroff-2.json
c6d895829b4611964978990ae1cb8a6a digest-cvaroff-3.json
Identical to C+6½'s baseline. Confirms the single class-E rewire is
cvar-OFF inert (and indeed XamShowGamerCardUIForXUID is not hit in
the 50M Phase A window, so even cvar-ON behavior is unaffected at
this horizon).
Gates 3a, 3b — Phase A matched-prefix table
| chain | C+6½ | XAM-audit | Δ |
|---|---|---|---|
| canary tid=6 → ours tid=1 (main) | 102158 | 102158 | 0 (preserved) |
| canary tid=4 → ours tid=11 | 5 | 5 | 0 |
| canary tid=7 → ours tid=2 | 26 | 26 | 0 |
| canary tid=12 → ours tid=7 | 2 | 2 | 0 |
| canary tid=14 → ours tid=9 | 39 | 39 | 0 |
| canary tid=15 → ours tid=10 | (no div) | (no div) | 0 |
No regressions on any chain. No advances on any chain — expected, because XamShowGamerCardUIForXUID is not exercised by the current boot window.
Gate 5 — unit tests
cargo test -p xenia-kernel --release — 146/146 pass. Same count
as C+6½ (no tests added or modified — XAM audit is rewire-only).
