CI/pipeline: - KERNEL_TARBALL passed as a YAML env literal '~' was never tilde-expanded and would have failed every hosted kernel-build dispatch; the path is now exported from the shell. Verified reproducible before the fix. - Every job gets timeout-minutes; boot smoke uses timeout -k so a wedged qemu is SIGKILLed instead of holding the job. - Tarball fetch + fail-closed sha256 verification deduplicated into build/fetch-kernel-tarball.sh (with curl retries), used by build-kernel.sh and both CI jobs. busybox fetch gains retries too. - ccache layer for kernel-build (cache keyed on defconfig+patches) recovers the incremental-compile speed the ephemeral-runner move cost. - build-kernel.sh now asserts every fragment option survived olddefconfig — merge_config -m pastes text and Kconfig silently drops unmet symbols. rs485-bridge: - pending-buffer cap (2x max RTU ADU) instead of unbounded growth; explicit accept-loop error handling with backoff instead of .flatten(); per-arm inline bounds instead of the string-keyed lookup whose default would have mis-bounded a future get-input; control-socket cleanup errors surfaced; flag-shaped values rejected in arg parsing; doc example uses a private mktemp dir. Test timing margins widened for contended runners (gap 25->120ms, 60x margin on the split-frame test). VM harness: - stage-1/stage-2 boot scripts share one validated slot parser and one by-name populator (qemu/rootfs/etc/warden-lib.sh) — the duplicated parser had already diverged on validation; userdata/oem mount failures now fail fast with a greppable sentinel; udhcpc fallback keys off the interface actually having an address; switch_root applet guarded. - boot-smoke delegates the qemu invocation to run.sh (machine shape lives in ONE place); run.sh port 0 disables a hostfwd. - mkimage: unknown partition names fail at build time; DISK_END is a max, not last-entry; --state keys validated as filenames. - portal-scenario: mock readiness is asserted (no silent fall-through), hostfwd port collisions retried, mount-failure sentinel fails fast. - ui-shot: fixed sleeps replaced with bounded screendump polling; the repaint assertion is real and documented as such. qmp.py loses its module-global and gains argv validation. Docs/scrub: bench-host paths and the site AP name removed from six more port docs and two evidence tables; path-bearing build artifacts (.elf, .map) untracked (the 154-byte firmware .bin is path-free and stays); ADR-0003 marked visibility-superseded by ADR-0007; stale section cross-reference fixed; flare-edge noted as private for outside readers; stale root-level review report removed per the new workspace rule.
