## Superseded by

| Archived | Superseded By |
|----------|---------------|
| `BOOT-PROCESS-IMPROVEMENT-PLAN.md` | `BOOT-PROCESS-AUDIT-2026-05-03.md` |
| `DEVICE-INIT-COMPREHENSIVE-IMPROVEMENT-PLAN.md` | `CONSOLE-TO-KDE-DESKTOP-PLAN.md` |
| `GREETER-LOGIN-ANALYSIS.md` | `GREETER-LOGIN-IMPLEMENTATION-PLAN.md` |
| `INTEL-HDA-IMPLEMENTATION-PLAN.md` | (Deferred — audio is P3 priority) |
| `ACPI-I2C-HID-IMPLEMENTATION-PLAN.md` | (Deferred — USB HID is primary input path) |
| `GRUB-INTEGRATION-PLAN.md` | GRUB is fully implemented (redbear-grub config, installer support, grub recipe) |
| `VFAT-IMPLEMENTATION-PLAN.md` | VFAT is fully implemented (fatd, fat-mkfs, fat-label, fat-check) |
| `USB-BOOT-INPUT-PLAN.md` | Superseded — USB HID in initfs, USB storage in initfs (Phase B2). Boot-input analysis remains historically useful; the live-input priority lives in `USB-IMPLEMENTATION-PLAN.md` v2. |
| `XHCID-DEVICE-IMPROVEMENT-PLAN.md` | Superseded by `USB-IMPLEMENTATION-PLAN.md` v2 — phases 1–7 absorbed into the new plan's P0–P3. |
| `USB-IMPLEMENTATION-PLAN-v1-2026-04.md` | Superseded by `USB-IMPLEMENTATION-PLAN-v2-2026-07.md` (archived). v1 overstated xHCI interrupt-driven operation; v2 rebased onto current source state and Redox 0.x USB HEAD. |
| `USB-IMPLEMENTATION-PLAN-v2-2026-07.md` | Superseded by `USB-IMPLEMENTATION-PLAN.md` v3 (current). v2 captured P0–P5 host-controller work; v3 expands to full USB first-class-citizen scope including UAS, error recovery, CDC ACM, HID report parsing, and hardware matrix. |
| `USB-VALIDATION-RUNBOOK-2026-07.md` | Historical validation runbook for P0 era. v3 validates against the expanded scope. |
| `ZSH-PORTING-PLAN.md` | Deferred indefinitely — ion is the default shell |
