ci: close the if that cost last night's release, and parse-check the rest (#122)
The Collect guard added to the publish job in #121 shipped without its closing `fi`. Run 32096242353 -- the first nightly to reach the new single publish job -- built all 107 devices, staged 219 assets, and then died in `bash -e` with line 25: syntax error: unexpected end of file from `if' command on line 14 before writing anything. No nightly-20260818-* release exists, `nightly` and `latest` still carry the 17th's images, and ci-gate went red. The gate did its job; there was simply nothing left to publish by then. Nothing caught it earlier because the publish job carries `if: github.event_name != 'pull_request'` -- there are no artifacts to publish on a PR, so the entire path is unreachable from PR CI by construction. Both of #121's runs were green without ever executing the step. #121 said as much ("none of this path can run on a pull request") and checked the four states offline, but offline-checking the logic does not check that the script parses, and that is what broke. So the one-line fix, plus the check that would have caught it in seconds without a runner: lint-workflow-shell.py parses every `run:` block in .github/workflows/ with `bash -n`, and lint.yml runs it on PRs and on master pushes that touch either. Notes on the checker: - ${{ }} is not shell, so each expression is replaced with a plain word first. That is a real limitation -- an expression interpolating shell syntax is checked as the word, not as what it expands to -- and the substitution preserves line counts so reported lines still point at the right line. --self-test asserts an unterminated `if` containing an expression is still rejected while the closed form passes, because the way this breaks is by making everything pass. - Steps are found by walking for any mapping with a `run:` key rather than by the jobs.*.steps[*] path, so nothing depends on guessing where they live, and a discovery floor fails the run if the walk stops finding them. A checker that silently checks nothing looks exactly like a clean tree. - Syntax only. It says nothing about quoting or `-e` semantics; a shellcheck pass wants per-block disables for the substitution above and is a separate change. actionlint would cover more and is worth considering later; keeping this narrow is what makes it noise-free now. ci-matrix.py classifies both new files as no-build. They were names it had never heard of, and unknown widens by design, so the first push queued all 107 devices to prove a one-line YAML fix -- #121, which touched only master.yml, ran 19. This PR still took the full matrix because it edits ci-matrix.py itself, which always widens; the selector is not trusted to pick a smaller matrix for its own changes. PyYAML is installed explicitly rather than inherited from the runner image, and the workflow declares `contents: read` rather than taking the repo default. Both from review; neither would have failed the job today. Verified: the checker flags the merged master.yml with the same message the runner gave, passes the fixed tree, and all five guard states behave as #121 intended -- normal night publishes, a broken download and a green-but-empty dist both fail, and a dead matrix with nothing built still exits clean.

ci: build pull requests, and only the devices they reach (#120)
* ci: build pull requests, and only the devices they reach This repo had no pull_request trigger at all. A change landed unbuilt, and the nightly found out the next morning -- or a user did. Turning PR CI on meant 107 device builds per push, which is why it stayed off. Almost every change here is one device: 639 of the file touches in the last 200 commits sit under a single devices/<dir>/, and the median commit reaches 2 devices. So narrowing first is what makes PR CI affordable at all. .github/scripts/ci-matrix.py maps the paths a PR touches to the devices that build them, and master.yml takes its matrix from it. The mapping is not written down, it is read off the tree the same way builder.sh reads it. builder.sh line 121 locates a device by its defconfig and copies that WHOLE devices/<dir>/ tree over the firmware clone, so the devices a file affects are exactly the devices whose defconfig shares its directory. That distinction is load-bearing: devices/common/ backs 18 targets and devices/apfpv/ backs 2, and treating a directory as one device would skip 17 real builds. A defconfig still names one target even inside a shared directory. THE NIGHTLY IS NOT NARROWED. builder.sh re-clones OpenIPC/firmware at HEAD on every run, so what a nightly builds is decided mostly outside this repo; master.yml already carries the scar of an earlier gate that skipped on this repo's HEAD and left upstream fixes invisible to users. Every event except pull_request gets the whole matrix, and --self-test asserts that for schedule, workflow_dispatch and push. Nothing on a pull_request may write a release. The three upload steps were gated only on an image existing, so with a pull_request trigger added they would have clobbered the published nightly and latest assets that users flash. They and the Telegram post are now guarded on the event. master.yml and check-adjacent plumbing get a 15-device smoke set rather than all 107: they decide how a build runs, not what it produces. --self-test enforces the cover -- every vendor, architecture, toolchain tuple and variant, plus both shared device directories -- rather than the list, so the set can be re-picked while the property holds. It already earned itself: the first run rejected my hand-picked set for missing arm-openipc-linux-gnueabi, which exactly one target in the tree has, and musleabihf. Also adds the CI Gate umbrella check, since a dynamic matrix cannot be named in branch protection and nothing reported a verdict before; and freezes the 7 defconfigs that exist but are in no matrix, so a device falling out of CI is a test failure rather than a silent skip. Replaying the last 200 commits: 20330 device-builds if every PR built everything, 5930 with the selector, 70.8% less, no coverage leaks. 43 of the 49 that still widen do so on paths that no longer exist (devices/ssc338q_apfpv/ before it became devices/apfpv/, the old top-level common/, a deleted builder-local.sh); restricted to commits whose paths survive, it is 78.2%. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * ci: derive the device list instead of writing it down Adding a camera IS the work in this repo: 8 of the 10 PRs open right now add a device, and 14% of recent commits do. With the list written down in ci-matrix.py, every one of those PRs also had to edit that file -- and a change to that file cannot narrow, because it is what does the narrowing. So registering one camera cost a full 107-device build to prove one device. The most common change got the worst outcome. The matrix is now every defconfig under devices/, minus a NOT_BUILT opt-out that keeps the 7 already in the tree but out of CI. Adding a device is creating its directory, nothing else, and it builds exactly that device. This is the opposite call to OpenIPC/firmware's ci-matrix.py, on purpose. There the matrix is curated -- 29 defconfigs are deliberately never built and boards are not the product -- so an explicit list is the honest description and an opt-out list would be noise. Here devices are the product and the list is just "all of them". The derived matrix is identical to the 107 master.yml carried: nothing lost, nothing gained. --self-test now checks the opt-outs still name real defconfigs, so a rename cannot leave a device silently building under its new name while its old name sits in NOT_BUILT. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * ci-matrix: own $GITHUB_OUTPUT instead of being redirected into it The docstring said the default mode writes $GITHUB_OUTPUT; it printed key=value lines to stdout and left the workflow to redirect them there. Raised in review on #120. Fixing the prose would have made the file honest, but the redirect itself is the weaker half. Under `>> ${GITHUB_OUTPUT}` every print() in this file is one keystroke away from corrupting the step outputs, and a crash between the first line and the last leaves a half-written file that Actions still reads. That the diagnostics go to stderr is what keeps it safe today -- a rule that has to hold forever, rather than a property of the code. So the script appends the three lines itself when $GITHUB_OUTPUT is set, and prints them when it is not, so a local run still shows its decision. --stdin never touches the file: it is the mode for reading with your eyes. master.yml drops the redirect, though leaving one in place would have been harmless -- with the file written directly, stdout is empty.
