- 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.

# 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:
|
|
the repo is public, and 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). |
|
|
|
|
## History: the self-hosted runner (retired)
|
|
|
|
`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.
