MechaCat02 ef93a4fa14 handoff: VSync/event-wedge fixes + iterate 2.A–2.BC research notes 
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.

STOP: a primary equivalence invariant failed. Downstream divergences are not interpretable until this is resolved. Re-run with --phase-b-dump-section-content on both engines and binary-diff the regions to localize.

Phase C handoff

Suggested attack order: σ first (structural), then γ ranked by object type (Thread > Event > Semaphore > Mutex > Timer > File > Other), then δ. ε and τ are catalog-only.
