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 C+22 broad-impact (2026-05-18)
Resolved
- None (escalation, no engine change).
Advanced
- None on main chain (C+21 baseline 104,607 preserved).
- None on sister chains (11/32/3/41/16 all preserved).
Persisted
- The scheduler-determinism class persists. Same root cause C+20 escalated. Multiple downstream effects of the same asymmetry now identified at idx 104,608 (wait.begin — absorbed by C+21) and idx 104,610 (post-wait nested-Enter branch — NOT absorbable per reading-error #23).
NEW
- Reading-error class #34: cold-run determinism depends on
input path form. Running ours against the loose
default.xexrather than the parent.isoproduces a different boot trajectory (40× more imports, 1.6M unimpl warnings, different thread-create sequence). All cold-vs-cold protocol runs MUST use the.isopath. ✓ documented ininvestigation.mdandcold-vs-cold-result.md.
Permanent infrastructure contribution
- None (no engine, diff-tool, schema, or emitter changes).
Tests
- 204 (unchanged from C+19/C+21).
