Closes three of the five gaps identified at v4.8:
- G-A1 (CRITICAL): AER/pciehp hash-dedup was order-dependent.
Fixed by v5.0 monotonic seq from pcid.
- G-A2 (CRITICAL): cpufreqd/thermald integration was broken.
Fixed by v5.1 real cpufreq scheme server.
- G-A3 (HIGH): pcid FIFO rollover could silently drop events.
Fixed by v5.0 MAX_EVENTS=256 + high_water_mark.
- G-A5 (HIGH): driver-manager restart re-applied recovery actions.
Fixed by v5.0 atomic-rename persistence at
/var/run/driver-manager/event-seqs.json.
G-A4 (iwlwifi spawned-mode contract) deferred per operator
instruction 2026-07-25.
v4.9 records:
- Five-gaps table with v4.9 status (4 fixed, 1 deferred)
- Adjacent-tech compatibility matrix v4.8 vs v4.9
- v5.x work program with implementation evidence + commit hashes
- Verification gate (tests: 112 driver-manager + 21 cpufreqd, all
passing; zero new warnings)
