- build-kernel.sh fragment assertion: survives a missing trailing newline (the read footgun, reproduced) and treats an absent symbol on a disable line as FATAL, symmetric with the enable arm. - fetch-kernel-tarball.sh checks the pin before downloading; both fetchers add --retry-connrefused. - mkimage rejects '.'/'..' state keys. - ui-shot: VM liveness checked before every QMP call, console.log preserved as evidence on every failure path, repaint deadline widened to 90s with the contended-runner rationale documented. - rs485-bridge: overflow discards back off one gap and rate-limit their log line, mirroring the accept-loop fix; clippy nit fixed. - .gitignore ignores *.elf/*.map so the untracked artifacts cannot silently return; CI shellcheck glob now covers build/ and the rootfs boot scripts (directives added for the deliberate in-guest source paths). - Docs: NPU parity row matches its sibling verification docs; line-pinned audit cross-references unpinned; CROSS_COMPILE documented in the build header; payload README lists warden-ui; ci-cd tense settled. Verified: guards negative-tested (bad state keys, no-newline fragment); boot smoke, portal scenario, ui-shot all PASS; 53 tests green; shellcheck clean across the widened glob; clippy zero.

RV1106 6.18 driver parity vs the 5.10 vendor kernel
Goal: every driver the panel's 5.10 kernel runs must work at ≥ parity on our
self-built 6.18. Source of truth = the running 5.10 system on warden-c8a3
(lsmod + /proc/interrupts, captured 2026-08-24). Verify each on hardware via
the A/B _b-slot loop (../docs/m2-boot-on-c8a3.md); [x] means confirmed on
c8a3, not just compiled.
