Second conciseness pass per review feedback: bullets and tables over prose (vendor-SDK failings, repo layout, sim models, kernel-port rationale, QEMU scenarios), duplicated content cut (provenance pointer, scenario prose the qemu README already carries). Also fixes two stale claims in architecture.md: the flared seam unification and real-image boot both landed (flare-edge #110, PR #8) but were still marked pending.

# 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)
|
|
because hosted minutes were metered on the private repo. Going public made
|
|
hosted minutes free and a self-hosted registration a fork-PR liability, so
|
|
ADR-0007 retired it. That runner's site records live in the 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.
