ci: select runners by capability, not by location - #242
Merged
Conversation
`runs-on` named `node-b`, `linux` and `x64`. The last two are advertised by every self-hosted runner and selected nothing. `node-b` is a *location*, and using it as a fleet selector is why proxmox-gha-public-rust and wsl2-gha-public-rust sat idle — both `busy: false` — while all three Node B workers were busy and jobs queued behind them at a p90 of 207s and a p99 of 1153s (2026-08-19 development-cycle review). Labels now name capabilities only. Jobs that need a Docker daemon keep `docker`/`publish`, which only the DinD-backed workers advertise; jobs needing Tailnet reachability keep `tailnet`. Every job in this repository was checked for Docker use before its label was dropped. The org policy gate is unaffected: it requires the literal `self-hosted` and rejects dynamic `runs-on`, both of which still hold.

node-b/linux/x64fromruns-on; keepsdocker/publish/tailnet. Part of the 2026-08-19 development-cycle review —node-bwas a location used as a fleet selector, leaving 2 of 5 runners idle while jobs queued at p90 207s. Every job audited for Docker use first. Policy gate unaffected (still requires literalself-hosted).
