A clone of this repo pushed to a new repository -- a private mirror, an internal re-host -- inherits .github/workflows together with its cron. The full platform matrix then runs on that owner's Actions bill, nightly and unattended. Forks are only partially covered: GitHub disables scheduled workflows there, but nothing covers a fresh repository, and nothing warns the owner. This mirrors OpenIPC/firmware#2255, where the same inherited cron was measured at 97 jobs and 2,146 billed minutes from a single unattended night, and never converged: publishing failed on the mirror, so the sha skip-gate could never engage and the matrix rebuilt in full every night. The rule: unattended runs happen only on the canonical repo. Anywhere else a workflow runs only if someone explicitly asked for it (workflow_dispatch), or if it is both free and attended (pull_request on a public repo). This is deliberately stricter than gating purely on cost -- a public re-host's minutes are free and its cron is still skipped, because a re-host quietly publishing nightly releases under its own name is a worse outcome than wasted minutes. master carries the guard on preflight; buildroot needs it and inherits the skip. manifest gates its cron-originated workflow_run path the same way, because a nightly whose jobs all skipped still completes and fires workflow_run. cleanup carries it on its weekly cron. build-one is dispatch-only and needs nothing. The pull_request clause is unreachable here today -- no workflow in this repo has a pull_request trigger -- and is kept on purpose: it is the clause that lets contributor PRs run, and omitting it would mean adding a pull_request trigger later silently skips CI on every fork. That over-block was the first thing reviewers caught upstream. Upstream impact is none: on OpenIPC/builder the first disjunct is true, so every added condition is a tautology and each job's if reduces to what it was before.
