# Windows host + client — implementation plan (superseded)

> **This was the original Windows host + client plan (2026-06-10 to 2026-06-14).** All of it
> shipped; its durable design rationale has been folded into
> [`windows-host-rewrite.md`](windows-host-rewrite.md), which is now the single Windows-host
> architecture / status / reference doc.

For the current picture, see:

- **`CLAUDE.md`** ("Where the work stands" → the Windows-host paragraph) — current features and live-validation status.
- **[`windows-host-rewrite.md`](windows-host-rewrite.md)** — architecture, validated invariants, operations, and the hard-won reference notes (`/INTEGRITYCHECK`, the `iddcx` bindgen knobs, the driver-port checklist). Its "Origins & design rationale" section absorbs the keep-worthy parts of this original plan.
- **git history** — the full original plan (SudoVDA control protocol, the no-GPU dev strategy, the phased host-first build order) is recoverable there.

Note: SudoVDA — the off-the-shelf virtual display this plan was built around — was replaced by the
all-Rust `pf-vdisplay` IddCx driver and deleted in commit `84a3b95`.
