 # Archived Documentation
 
+Last synced: 2026-07-13 — this archive inventory is dynamically maintained and
+tracks only files that currently exist in this directory.
+
 These documents were written during earlier phases of Red Bear OS development.
 They contain historical context and analysis but are **superseded** by more
 current plans. They are kept for reference only.
 
-## Superseded by
+## Inventory
 
-| Archived | Superseded By |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-| `USB-BOOT-INPUT-PLAN.md` | Superseded — USB HID in initfs, USB storage in initfs (Phase B2).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-| `XHCID-DEVICE-IMPROVEMENT-PLAN.md` | Superseded by `USB-IMPLEMENTATION-PLAN.md` v2 — phases 1–7 absorbed into the new plan's P0–P3.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-| `USB-IMPLEMENTATION-PLAN-v1-2026-04.md` | Superseded by `USB-IMPLEMENTATION-PLAN-v2-2026-07.md` (archived).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-| `USB-IMPLEMENTATION-PLAN-v2-2026-07.md` | Superseded by `USB-IMPLEMENTATION-PLAN.md` v3 (current).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 |
+| Archived | Status |
+|----------|--------|
+| `ACPI-I2C-HID-IMPLEMENTATION-PLAN.md` | Deferred; USB HID remains the primary input path. |
+| `INTEL-HDA-IMPLEMENTATION-PLAN.md` | Deferred; audio remains a later priority. |
+| `KERNEL-SCHEDULER-MULTITHREAD-IMPROVEMENT-PLAN.md` | Historical scheduler analysis kept for reference. |
+| `README.md` | Archive metadata only. |
+| `repo-governance.md` | Historical governance note kept for reference. |
+| `USB-BOOT-INPUT-PLAN.md` | Superseded by the current USB implementation planning. |
+| `USB-VALIDATION-RUNBOOK-2026-07.md` | Historical validation runbook for the earlier USB phase. |
+| `XHCID-DEVICE-IMPROVEMENT-PLAN.md` | Superseded by the current USB implementation planning. |

+## Supersession notes
+
+- `USB-BOOT-INPUT-PLAN.md` and `XHCID-DEVICE-IMPROVEMENT-PLAN.md` were
+  absorbed into the newer USB implementation work.
+- `ACPI-I2C-HID-IMPLEMENTATION-PLAN.md` and `INTEL-HDA-IMPLEMENTATION-PLAN.md`
+  remain as deferred historical references.
+- `KERNEL-SCHEDULER-MULTITHREAD-IMPROVEMENT-PLAN.md` and `repo-governance.md`
+  are retained as archive-only context.
