 # Red Bear OS — `pci-spawner` → `driver-manager` Migration Plan
 
-**Document status:** v4.4 canonical planning authority (supersedes v4.3: v4.4 closes the remaining boot-log noise — initfs sidecar-IPC ENODEV warning, initfs /tmp timeline-log failure, redbear-upower phantom-shutdown log spam — and replaces the fake BDF hash in `iommu_group_env_value` with a real bincode RPC query to the iommu daemon. v4.3 in turn superseded v4.2: v4.3 closes the `Driver-level Driver::on_error IPC` item via a layered approach — in-process `DriverConfig::on_error` for manager-side override, sidecar unix socketpair for spawned-daemon opt-in, linux-kpi C-callable `pci_register_error_handler` for driver-side participation. v4.2 in turn superseded v4.1: v4.2 closes the `acpid pci_fd` item and adds per-vendor firmware recipes. v4.1 in turn superseded v4.0: v4.1 closes the three P3 items the v4.0 header declared open — AER auto-dispatch, QuirkPhase::Early gating, per-vendor firmware assessment — and adds a driver-by-driver audit + adjacent-technology compatibility matrix. v4.0 in turn superseded v3.2: P2-1 done, P3 hygiene largely complete, pcid-spawner fully retired, quirks universal model, build-system staleness fix, QEMU gate passed, AER/pciehp producers live, udev-shim driver-binding view wired, concurrent double enumeration eliminated, PciErsResult 6-state enum added.)
+**Document status:** v4.5 canonical planning authority (supersedes v4.4: v4.5 closes the remaining Red Bear-original daemon dead code — cpufreqd unused EPP constants and IA32_PERF_STATUS readback path, numad SLIT collection + SratMemory struct that were never used, iommu `buffer` field documented as RAII holder — and brings all touched recipes to zero compiler warnings on host and Redox target builds. v4.4 in turn superseded v4.3: v4.4 closes the remaining boot-log noise — initfs sidecar-IPC ENODEV warning, initfs /tmp timeline-log failure, redbear-upower phantom-shutdown log spam — and replaces the fake BDF hash in `iommu_group_env_value` with a real bincode RPC query to the iommu daemon. v4.3 in turn superseded v4.2: v4.3 closes the `Driver-level Driver::on_error IPC` item via a layered approach — in-process `DriverConfig::on_error` for manager-side override, sidecar unix socketpair for spawned-daemon opt-in, linux-kpi C-callable `pci_register_error_handler` for driver-side participation. v4.2 in turn superseded v4.1: v4.2 closes the `acpid pci_fd` item and adds per-vendor firmware recipes. v4.1 in turn superseded v4.0: v4.1 closes the three P3 items the v4.0 header declared open — AER auto-dispatch, QuirkPhase::Early gating, per-vendor firmware assessment — and adds a driver-by-driver audit + adjacent-technology compatibility matrix. v4.0 in turn superseded v3.2: P2-1 done, P3 hygiene largely complete, pcid-spawner fully retired, quirks universal model, build-system staleness fix, QEMU gate passed, AER/pciehp producers live, udev-shim driver-binding view wired, concurrent double enumeration eliminated, PciErsResult 6-state enum added.)
