- Scheme gains /recover: write '<pci_addr> <reset_device|rescan_bus| disconnect>' to trigger AER recovery. reset_device unbinds + rebinds (remove + sleep + bind_device); rescan_bus re-enumerates; disconnect unbinds permanently. Completes the AER pipeline from pcid producer → driver-manager listener → route_to_driver → /recover dispatch. - Plan v4.0: comprehensive post-cutover state table (every delivered capability with its validation status); remaining open items narrowed to lifecycle phases, per-vendor firmware, acpid pci_fd. - AGENTS.md + docs/README.md bumped to v4.0.
