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ADR-0004 marked superseded-in-part; docs/ci-cd.md rewritten (site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.

Phase 4+5 of the device sim:
- Display + touch verified end-to-end: virtio-gpu at 720x720 (fbdev
emulation) renders the real WardenOS dashboard from the static LVGL
fbdev+evdev UI build (flare-edge qemu-vm-support tools/build-ui-vm.sh);
QMP input-send-event taps the Metrics tab and qemu/tests/ui-shot.sh
asserts the repaint from screendumps. Two load-bearing QEMU flags found
and documented: -global virtio-mmio.force-legacy=false (gpu/input are
VERSION_1-only) and the 200ms press hold (an instantaneous press+release
lands inside one LVGL indev poll and never clicks).
- qemu/tests/qmp.py: minimal QMP client (screendump, tap, quit).
- stage-2 init starts warden-ui when present and fb0 exists.
- docs/decisions/0006-qemu-device-sim.md: virt-not-custom-board, the
enters-at-kernel boundary, fragment policy, naming, consequences.
- docs/architecture.md: new section 7 (device emulation), order-of-work
item 7; modbus cross-reference to the bridge.
- qemu/README.md: emulated-vs-not table, scenarios, gotchas, host/runner
requirements. docs/ci-cd.md: runner needs one-time qemu-system-arm
install (fail-closed smoke until then, [maintainer]-gated). Repo README updated.
Final sweep on this commit: shellcheck clean, bridge 7/7 tests, boot smoke
PASS, portal scenario PASS (check-in + fw pull + signed .wfw download),
ui-shot PASS (touch navigates to Metrics) — all under the final flags.

Point the badges job's branch guard at refs/heads/main and update the README /
ci-cd docs to name main as the canonical branch, ahead of establishing main from
bringup as the SDK's first main commit.

First recursive code-review-harness pass over the authored SDK code (sim/,
config-lint, flowgen, drivers/{relays,freshness}, build/, ci.yml). Four parallel
dimension reviewers; all findings at every severity corrected per workspace rule.
Correctness / reliability:
- freshness.c min_budget_ms: use a `seen` flag, not `best==0`, as the empty
sentinel — a zero-tolerance (max_stale_ms==0) binding was silently widened to a
looser neighbour's budget. Regression test added; still 66/66 MC/DC.
- config-lint parse_reserved_ranges: match `reg` as a whole property token (ident
boundary before, `=` after) so `reg-names` / a `region-*` label no longer
mis-parses into a bogus reserved range.
- config-lint loader check: fail closed — flag any loader with a LOAD_ADDR that is
not a known-safe boot component, instead of only known MCU names, so a future
coprocessor ("Rtos"/"Bl32") can't slip past the 0x40000-brick gate.
- build-kernel.sh: sha256 verification is now mandatory (refuse to build if the pin
is missing) and the mktemp scratch tree is removed on exit (trap), while a
caller-provided WORK is left intact for CI artifact upload.
Test quality:
- freshness: added the age==max_stale boundary case and a clock-wraparound
(now < last_ok) fail-safe-to-UNKNOWN test.
- relays: unsetenv(WARDEN_GPIO_ROOT) at main() so the NULL-env arm is hermetic.
Security / CI:
- ci.yml: top-level `permissions: contents: read` (badges overrides to write);
pin taiki-e/install-action to commit SHA (v2.86.7).
Maintainability / docs:
- drivers/enforce-mcdc.sh: one shared, name-derived gate replaces the two
copy-pasted per-driver scripts; Makefiles call ../../enforce-mcdc.sh.
- docs/architecture.md: §3/§4/§6/§7 rewritten to match reality — NPU/RGA models,
config-lint, and the relays+freshness MC/DC harnesses are done; kernel §6 now
reflects the 5.10->6.18.46 forward-port (ADR-0001), not the superseded plan44/6.6.
- README: status blurb + layout table corrected (kernel/, .github/; stale ci/ and
patches/ descriptions fixed). hpmcu "8 tests" -> 7 in docs.
- freshness.{c,h}: ADR reference points at flare-edge ADR-0004 (warden-sdk's
ADR-0004 is the CI runner — number collision).
- normalize rustfmt drift across sim/ + config-lint.
All green: sim 37 tests, config-lint 8 tests, both drivers 100% MC/DC (relays
40/40, freshness 66/66), clippy clean under -D warnings, gitleaks clean.

test job runs cargo test across sim + config-lint and cargo-llvm-cov line coverage
on the sim crate; badges job renders loc/tests/coverage shields on push to bringup
([skip ci] + paths-ignore loop guard). mcdc/bench/kernel-build jobs land with
P2/P4/P1. README carries the CI + badge row.

The c8a3 brick was a memory-map fault no behavioural sim can catch: a
boot-loaded coprocessor firmware dropped at 0x40000, which is a reserved-memory
carve-out on Thunder-Boot boards but plain kernel RAM on ours. config-lint is
the static gate for it — parse the rkbin loader .ini for every LOADERn=Hpmcu
LOAD_ADDR, parse the target devicetree for reserved-memory ranges, fail if any
MCU load lands outside a reservation.
Tests encode the brick as a regression against the REAL Thunder-Boot .ini
(Hpmcu@0x40000): fails with no rtos@40000 node, passes once reserved; our
board's non-TB loader (no boot-loaded MCU) always passes. 6/6 green; CLI
verified against the on-disk rkbin .ini files.

New from-scratch SDK for WardenOS (RV1106). First substance: the hardware
simulator's core — a MemBus register/SRAM seam (one trait, real /dev/mem backend
on device + in-memory SimBus on host) and a faithful port of the HPMCU watchdog
firmware (hpmcu/watchdog/main.c) as HpmcuSim, with 8 tests validating boot-grace
fire, heartbeat-timeout, disarm stand-down, and the flared arm-within-grace safety
property (no boot-loop) — all off-device, in a virtual clock, in <1ms.
This closes the gap the Explore map flagged: flared's devmem.rs/hpmcu.rs are the
only register-touching modules with zero tests. README lays out the SDK vision
(modern kernel, tiered driver MC/DC, proper RGA/HPMCU/NPU simulator, own repo).
