- P19-init-startup-hardening: Replace panic-grade expect/unwrap in init startup paths (getns, register_scheme_to_ns, setrens, filename parsing) with graceful error handling and logging - P19-acpid-startup-hardening: Replace panic-grade calls in acpid with graceful degradation (rxsdt read failure → warn + exit 0, SDT parse → error + exit 1, I/O privilege → fatal, scheme registration → fatal, setrens → warn + continue, event loop errors → log + continue) - P18-9-msi-allocation-resilience: Regenerate with git diff -U0 -w format for maximum context resilience - fetch.rs: Change --fuzz=0 to --fuzz=3 for resilient patch application - AGENTS.md: Document robust patch generation technique as mandatory - Add P4/P5/P6/P7 patches (estale, dmi, i2c, ps2d hardening) - Add P21 kernel x2apic SMP fix patch - Multiple local recipe source improvements (redox-drm, driver-manager, driver-acpi, thermald) - Config updates for redbear-mini and redbear-device-services - Subsystem assessment document
