# Archived Documentation

Last synced: 2026-07-27 — 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They contain historical context and analysis but are **superseded** by more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.

## Inventory

| Archived | Status |
|----------|--------|
| `ACPI-I2C-HID-IMPLEMENTATION-PLAN.md` | Deferred; USB HID remains the primary input path. |
| `BUILD-SYSTEM-IMPROVEMENTS.md` | Historical build-system improvement plan; absorbed into `../../AGENTS.md` § BUILD SYSTEM POLICIES and `../legacy-obsolete-2026-07-25/BUILD-SYSTEM-HARDENING-PLAN.md`. |
| `DRIVER-MANAGER-MIGRATION-PLAN.md` | v1.0 → v5.9 round-by-round migration plan (2861 lines, 182 KB). Historical record of pcid-spawner → driver-manager cutover and all v5.x work. Superseded by `../DRIVER-MANAGER.md` (post-v5.9 systematic assessment). Read the current-state doc; read this archive for round-by-round history. |
| `IMPLEMENTATION-MASTER-PLAN.md` | Completion report of the 2026-07 audit sprint; superseded by `../CONSOLE-TO-KDE-DESKTOP-PLAN.md`. |
| `IMPROVEMENT-PLAN.md` | RESOLVED quality-audit plan (38/38); historical reference only. |
| `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. |
| `RELIBC-IPC-ASSESSMENT-AND-IMPROVEMENT-PLAN.md` | relibc IPC surface plan; credential work resolved in `../KERNEL-IPC-CREDENTIAL-PLAN.md`. |
| `SLEEP-IMPLEMENTATION-PLAN.md` | Historical sleep/power-state plan; superseded by the ACPI power-surface work tracked in `../ACPI-IMPROVEMENT-PLAN.md`. |
| `repo-governance.md` | Historical governance note kept for reference. |
| `SOURCE-ARCHIVAL-POLICY.md` | Absorbed into `../../AGENTS.md` § RELEASE MODEL / SOURCE-OF-TRUTH RULE. |
| `STUBS-FIX-PROGRESS.md` | Final-state log of the completed stub→real-code campaign. |
| `SYSTEM-STABILITY-AND-UPSTREAM-SYNC-PLAN.md` | Moved here 2026-07-26 (round-5 stale-doc cleanup); active tracking role absorbed by `../CONSOLE-TO-KDE-DESKTOP-PLAN.md` and the current subsystem plans. |
| `UPSTREAM-SYNC-PROCEDURE.md` | Moved here 2026-07-27 from `../legacy-obsolete-2026-07-25/`. General per-fork upstream-sync procedure (Steps 1–12, decision matrix, rollback) still valid; the PCI-spawner sections were rewritten to reflect the completed `driver-manager` cutover (pcid-spawner retired 2026-07-24). Superseded for PCI-driver architecture by `../DRIVER-MANAGER.md`. |
| `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.
- 2026-07-18 archival (release-bump cleanup): `IMPROVEMENT-PLAN.md`,
  `IMPLEMENTATION-MASTER-PLAN.md`, `STUBS-FIX-PROGRESS.md`,
  `RELIBC-IPC-ASSESSMENT-AND-IMPROVEMENT-PLAN.md`, `SOURCE-ARCHIVAL-POLICY.md`
  moved here from `local/docs/`. All inbound references were updated to the
  `archived/` paths in the same pass.
- 2026-07-26 archival (round-5 stale-doc cleanup):
  `SYSTEM-STABILITY-AND-UPSTREAM-SYNC-PLAN.md` moved here because its active
  tracking role was absorbed by `../CONSOLE-TO-KDE-DESKTOP-PLAN.md` and the
  current subsystem plans.
- 2026-07-27 archival (PCI-spawner doc cleanup):
  `UPSTREAM-SYNC-PROCEDURE.md` moved here from
  `../legacy-obsolete-2026-07-25/`. Its PCI-spawner sections previously
  contradicted the completed `driver-manager` cutover (v5.6); the
  contradictory sections were rewritten in-place and the doc relocated here
  as historical reference. Inbound references in `DRIVER-MANAGER-MIGRATION-PLAN.md`,
  `NETWORKING-IMPROVEMENT-PLAN.md`, and `PACKAGE-BUILD-QUIRKS.md` were
  repointed to this `archived/` path in the same pass.
- 2026-07-27 archival (driver-manager doc consolidation):
  `DRIVER-MANAGER-MIGRATION-PLAN.md` moved here. The 2861-line v1.0 → v5.9
  round-by-round plan was replaced by `../DRIVER-MANAGER.md` (~685 lines,
  current-state focused). The new doc adds the post-v5.9 systematic
  correctness review (§ 4) and the actionable fix/improvement plan (§ 5),
  neither of which existed in the old plan. Historical round-by-round
  detail is preserved in this archive. Inbound references in
  `../HARDWARE-VALIDATION-MATRIX.md`, `../CONSOLE-TO-KDE-DESKTOP-PLAN.md`,
  `../REDBEAR-FULL-SDDM-BRINGUP.md`, `../evidence/driver-manager/D5-AUDIT.md`,
  `../../AGENTS.md`, `../../../docs/README.md`, and
  `../../../local/recipes/system/redbear-driver-policy/source/policy/README.md`
  were repointed to `../DRIVER-MANAGER.md` in the same pass.
