# Orao 2026 v0.5 — BOS/SM i VDOS

- VDOS is treated as rebranded IDOS by user-authorized working assumption
- Floppy reduced to 140 KiB, one DOS volume
- HDD remains 20 MiB with temporary 140-KiB volumes; final layout deferred
- BOS/SM and VDOS subset execute in CPU code; own native ABI, no recovered ROM claim

- Native ROM service dispatcher and context preservation
- Native command loop, DOS 3.3 VTOC/catalogue and bounded binary files
- 140-KiB floppy; 146 HDD volumes with boundary isolation
- Per-PID hardware leases, native IPC wrappers, file import/export and native execution
