BOOT-PROCESS-AUDIT-2026-05-03.md: full daemon-by-daemon review
of boot sequence from power-on to login prompt. Covers:
- 25+ daemons assessed (critical path, input, display, hardware,
  storage, network, audio, UI, system services)
- Hardware initialization completeness matrix
- ion shell analysis (strengths/gaps vs bash/dash)
- Stale documentation inventory

Archived 5 superseded plans to local/docs/archived/:
- ACPI-I2C-HID, BOOT-PROCESS-IMPROVEMENT, DEVICE-INIT,
  GREETER-LOGIN-ANALYSIS, INTEL-HDA-IMPLEMENTATION

Improvement plan: 5 phases (boot reliability, drivers, UX,
documentation, security) across 6 weeks
