# Emulator Baseline Register

## v206 — Known-Good Behavioral Baseline

User-confirmed live behavior:

- Windows sees one emulated `HL-DT-ST DVD-ROM GDR8050L`;
- VLC reads the locked/video partition before authentication;
- `unlockdrive.exe` authenticates and exposes the Xbox game view;
- stateful eject policy is the regression reference.

The exact v206 package is not embedded in this snapshot. Its scope is preserved
without inventing source-level proof.

## v258 — Current Handoff Baseline

Exact package SHA-256:

```

v258 closes READ(10) parser/descriptor state handoff while keeping the
firmware-derived media-window delta, single-call-stack proof, READ(12)
equivalent closure, and exact timer/MMIO behavior open.

## Negative Lineage

v235-v249 Windows-runner automation caused instability and must not be revived
without explicit user direction. v234 restored the stable line used by v250-v258.
