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ADR-0003 marked visibility-superseded by ADR-0007; stale section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.

Decision/directive lines keep their dates and content, drop the name;
hands-on confirmations become "confirmed by hand at the panel"; a dangling
CLAUDE.md reference becomes "repo policy". Upstream vendor author
attributions in the GPL kernel sources (MODULE_AUTHOR, copyright headers,
LKML citations) are third-party legal attributions and stay.

Preparing the repo to go public (ADR-0007):
- CI: kernel-build moves from the self-hosted runner to ubuntu-latest
(installs its own cross toolchain + qemu, caches the pristine tarball).
On a public repo a registered self-hosted runner is reachable from
approved fork-PR workflows — i.e. arbitrary code on private
infrastructure — and the build never actually needed the SDK host.
ADR-0004 marked superseded-in-part; docs/ci-cd.md rewritten (site
specifics now live only in the private deployment log).
- Licensing: LICENSE gains the GPL-2.0 carve-out for patches/ and the
kernel source excerpts (Linux derivatives; per-driver provenance was
already tracked in PROVENANCE.md); patches/README.md states it too.
- Scrubbed from the tip: bench-unit dev credentials and its gadget IP
(m2-boot notes), the site AP SSID+BSSID and a neighboring AP's BSSID
and the device WLAN MAC (wifi bring-up evidence — BSSIDs are
geolocatable), the runner mesh IP. NOTE: these remain in git history;
decision on a pre-publication history rewrite is separate.
- Emoji cleanup across 21 tracked files (kernel port docs, review report,
enforce-mcdc.sh) per repo text conventions: status marks became
[x]/[wip]/[ ]/OK plain text.
- "[maintainer]-gated" process phrasing normalized to "maintainer-gated"
(attributions in dated evidence docs kept).
Verified: zero emojis tracked; scrub grep clean; patches carry no internal
references; ci.yml parses; shellcheck unchanged.

RTC: ported the vendor rockchip,rv1106-rtc driver (rtc-rockchip.c) to 6.18 — one
API delta (rtc_register_device -> devm_rtc_register_device). Verified on
warden-c8a3: /dev/rtc0 registers and reads.
tsadc thermal: ported the rv1106 data + rk_tsadcv9_initialize + the TSADCV9/VOGRF
macros + code table from the vendor; adapted .chn_id[SENSOR_CPU] -> .chn_offset
for 6.18. Verified: thermal_zone0 "soc-thermal" reads 39.8 C.
i2s-tdm: rv1126 fallback compatible added (DAI builds; sound card needs the acodec
port next). saradc still -22 (clk-rv1106 SARADC divider — deferred).
Includes the NPU + RGA open-source port plans (research): rknpu kernel driver is a
small port (RV1106 config already in the vendor driver; 4 dead-code headers need
compat stubs) but no open userspace exists for this NPU gen; RGA = port the vendor
char-dev rga3 driver (WardenOS's librga uses /dev/rga, not V4L2), + a cma pool +
hrtimer_setup. All ports are open source (vendor C source / mainline siblings).
