+## 18. v6.0 → v6.0-impl Changelog (2026-06-09 implementation session)
+
+The v6.0 plan was produced on 2026-06-08. On 2026-06-09, an extensive implementation session
+landed 346+ commits across multiple repos, addressing the bulk of the v6.0 plan's stub
+elimination, fork establishment, and driver wiring work. This section summarizes what
+landed and what remains for subsequent sessions.

+
+**P3 (HID core extraction) — 4/4 DONE**: `local/recipes/drivers/redbear-hid-core/` (new crate, 2664 LoC, 43 unit tests), usbhidd/i2c-hidd/intel-thc-hidd wired to it.

+
+### 18.3 Red Bear forks established (12 forks)
+
+Per the **NO OVERLAY-STYLE PATCHES — SCOPED POLICY (AMENDED 2026)** (commits `5396e6c3c` initial, `2b72f61e4` amendment):
+
+| Fork | Path | Status |
+|------|------|--------|
+| `base` | `local/sources/base/` | pre-existing, on `0.2.3` |
+| `bootloader` | `local/sources/bootloader/` | pre-existing |
+| `installer` | `local/sources/installer/` | pre-existing |
+| `kernel` | `local/sources/kernel/` | pre-existing |
+| `libdrm` | `local/sources/libdrm/` | NEW — `26e0c24 libdrm: Red Bear fork with redox patches applied` |
+| `mesa` | `local/sources/mesa/` | NEW — `0ecd6b66c` upstream + `a7e54995f` Redox fixes |
+| `pipewire` | `local/sources/pipewire/` | NEW — `829d32e` + `016669f` |
+| `redox-drm` | `local/sources/redox-drm/` | NEW — `bd787d3` + Gap 3/5/8 fixes |
+| `redoxfs` | `local/sources/redoxfs/` | pre-existing |
+| `relibc` | `local/sources/relibc/` | pre-existing |
+| `userutils` | `local/sources/userutils/` | pre-existing |
+| `wireplumber` | `local/sources/wireplumber/` | NEW — `df92c0b` |
+
+### 18.4 QEMU boot validation
+
+- `local/scripts/test-redbear-full-qemu.sh` (297 lines, executable) — QEMU boot test launcher with `snapshot=on,readonly=on` to protect build artifacts
+- 3 boot logs + 3 analysis docs in `local/docs/boot-logs/`
+- **300s capture reached**: PCI enumeration → pcid-spawner → nvmed (multi-queue) → virtio-blkd → ahcid
+- **Real bug found and fixed**: `virtio-blkd` panicked on `assert_eq!(*status, 0)` when boot drive is read-only (commit `cffacf59 virtio-blkd: handle read-only drives gracefully (VIRTIO_BLK_F_RO feature)`)
+- **Did NOT reach in 300s**: D-Bus, KWin, SDDM, login prompt (would need redbear-full ISO + further fixes)
+
+### 18.5 What remains (the v6.0-impl→v7.0 path)
+
+| Block | Status | Note |
+|-------|--------|------|
+| Build the `redbear-full` ISO | ❌ Blocked | Pre-existing build-system symlink loop in `local/recipes/*/recipe.toml` blocks cookbook rebuild |
+| Mesa fork → EGL Wayland platform working | ❌ Not validated | `local/sources/mesa/` fork established; Wayland EGL flag in mainline; never actually built |
+| QML gate (Kirigami QML_OFF macros) | ❌ Blocked | Real QML runtime requires JavaScript engine + QML parser + Wayland windowing — multi-engineer effort |
+| Real `libdrm` patches | ❌ Not validated | Fork created; patches in fork; never rebuilt against actual mesa |
+| Wayland protocols in redbear-compositor | ❌ Missing | xdg-shell, xdg-output, xdg-decoration, wl_keyboard, wl_pointer, wp_viewporter, linux-dmabuf — only 5/15 of the canonical protocol surface |
+| Hardware GPU enablement | ❌ QEMU only | Intel ARC Xe driver, AMD radeonsi — not yet started |
+
+### 18.6 Architectural decisions documented
+
+- **v6.0 unified input**: single evdev producer at `/scheme/input/evdev` (inputd ring buffer), consumed by evdevd, exposed as `/dev/input/eventN` for libinput.
+- **v6.0 compositor decision**: KWin is primary; redbear-compositor is greeter-only.
+- **NO OVERLAY-STYLE PATCHES — SCOPED POLICY (AMENDED 2026)**: Rule 1 for in-tree components, Rule 2 for big external projects.
+- **12 Red Bear forks established** as durable source-of-truth.
+- **QEMU boot test pattern**: `snapshot=on,readonly=on` for drive attachment to prevent ISO corruption during test runs.
 - §9 v6.0 config changes to redbear-full.toml
 - §10 Evidence model (recalibrated to v6.0 phases)
 - §11 Risk register (12 risks including QML, KWin, PipeWire, xwayland)
