| # Runner router: use the shared org-level self-hosted `copse-checks` pool when | |
| # one is online, else GitHub-hosted. The pool is the unified runner image in | |
| # copse-dev/agent-pane's ci-runners/ (registered at org scope), shared across | |
| # org repos — this repo only needs the light check tier, which those runners | |
| # carry. Same fail-open contract as agent-pane's pick-runner (see that repo's | |
| # ci.yml for the full rationale): ANY uncertainty (fork PR, no PAT, API error, | |
| # none online) falls back to hosted, so CI never queues on a runner that isn't | |
| # there. Fork PRs always take hosted so untrusted code never lands on a | |
| # self-hosted box (and GitHub withholds secrets from fork runs anyway, so the | |
| # RUNNERS_PAT is never exposed to them). | |
| # | |
| # To enable self-hosted routing, add a repo (or org) secret RUNNERS_PAT with | |
| # org runner read (classic `admin:org`, or fine-grained organization | |
| # "Self-hosted runners: Read"). Without it, this stays on hosted. | |
