The repo's documentation framed it as a support repo for one product (WardenOS). Since going public the real audience is anyone with a Luckfox Pico 86 Panel: a maintained 6.18 kernel, an off-device development loop, and a device simulator that exist nowhere else for this board. Reframe the README and top-level docs board-first, with WardenOS documented as the downstream consumer it is (ADR-0008). Also an editorial pass over the whole doc set: - every H1/H2 is now a short title, not a sentence (ADRs, qemu/, patches/, drivers/, architecture, NPU feasibility, config-lint, payload); workflow flowchart titles fixed at the source in tools/flowgen.py and regenerated with fresh bench numbers - README Quick Start commands verified against the scripts; requirements corrected (curl, bare python, gcc >= 14) and the MC/DC gate added as a step (run green locally on gcc 14.2) - dropped the 'needs python (not python3)' vendor dig: build-kernel.sh inherited the same requirement (filed #10 to remove it) - glossed MC/DC and HPMCU on first use; marked the tests/uboot-ab reference as flare-edge; deduplicated the three-simulator list into the root README table

CI/CD
.github/workflows/ci.yml — every job runs on GitHub-hosted ubuntu-latest.
No self-hosted runner is (or may be) reachable from this repo's workflows —
on a public repo, a fork PR that gets one approved run could otherwise
execute code on private infrastructure (ADR-0007).
Jobs
| Job | Runner | What it does |
|---|---|---|
test |
ubuntu-latest | cargo test (sim + config-lint + qemu/rs485-bridge) + cargo-llvm-cov line coverage on sim; outputs passed/coverage. |
mcdc |
ubuntu-latest | 100% MC/DC enforced on every drivers/*/test (gcc-14 -fcondition-coverage). |
bench |
ubuntu-latest | Smoke-runs the sim + rs485-bridge micro-benchmarks; emits ns/op trend JSON. |
patches-apply |
ubuntu-latest | Fetches pristine linux-6.18.46 (cached, sha256-verified) and applies patches/* in order. |
qemu-tools |
ubuntu-latest | shellcheck on qemu/**.sh; builds the initramfs (pinned busybox) and the A/B disk image. |
kernel-build |
ubuntu-latest, dispatch-only | apt-installs the cross toolchain + qemu, build/build-kernel.sh → zImage + rv1106-warden.dtb, QEMU -M virt boot smoke (fail-closed), artifact upload (best-effort). Trigger: gh workflow run ci.yml. |
prune-artifacts |
ubuntu-latest, dispatch-only | Deletes kernel-rv1106 artifacts beyond the newest 3. |
badges |
ubuntu-latest | Renders loc/tests/coverage shields on push to main ([skip ci] + paths-ignore loop guard). |
Runner History
kernel-build originally ran on a repo-scoped self-hosted runner (ADR-0004,
2026-08-25, verified end-to-end) because hosted minutes were metered on the
private repo. Going public made hosted minutes free and made a self-hosted
registration a liability, so ADR-0007 moved the job to ubuntu-latest and
retired the registration. Site-specific install records for that runner live
in our private deployment log, not here.
Badges
Static shields SVGs are committed by the badges job. The GitHub-native
ci.yml status badge works live regardless.
