Every PR and every push to main therefore serializes + ~70 s of verify + ~10 s of Gitleaks on a single executor; bursts (the + documented ~60 queued runs, and the 34-open-PR fleet incidents) queue + linearly. +- Current queue depth at inspection: **0 queued / 0 in progress** (16 open + PRs). The burst is intermittent, but the structural single-executor limit + is unchanged — the choke point re-appears with every fleet fan-out. +- Measured per-run cost (run 31824436668, verify job 94845093580): + npm ci 3 s (cache hits), npm test 30 s, Chromium render-blocking check + 27 s, wrangler dry-run 2 s. A second runner roughly halves fleet drain + time for verify and Gitleaks alike. +- The VPS (netcup-rs2000, 8 cores) already hosts the identical hardened + runner pattern per repo (e.g. 0509 runs three instances + `verify1/2/3` on one slice), so the scale-out approach is the established + fleet convention, not a new pattern. + +## Change + +`.github/workflows/ci.yml` and `.github/workflows/secret-scan.yml`: replace +the single-label `runs-on` with a 2-element matrix over the per-instance +runner labels `tinystudio-io-verify1` / `tinystudio-io-verify2` (both carry +the shared `self-hosted, linux, x64, vps-verify` labels). The job names +(`verify`, `Gitleaks`) are unchanged, so the branch-protection required +checks keep their exact contexts. + +Rationale for keeping everything on self-hosted VPS runners: governance +(`agent-contract.md`, `governance.md`) prefers VPS CI runners, and prior PRs +(#64/#65/#66) deliberately moved these jobs off `ubuntu-latest`; moving +Gitleaks to GitHub-hosted would also split the secret-scan evidence trail. + +## Not done in this PR (host provisioning) + +The GitHub-side runner does not exist yet. Provisioning it requires running +on the VPS as root/sudo (creating user `ghatiny-verify2`, installing the +runner under `/var/lib/github-runners/tinystudio-verify2`, adding the systemd +unit instance + label `tinystudio-io-verify2`, and starting it). That is +outside the repo's owned files, so it is documented here as the follow-up +step; until it runs, the verify2 matrix leg stays queued ("No runner +satisfies...") and verify/Gitleaks behave exactly as today on verify1. + +## Verification + +- YAML parses (node yaml); workflow job names unchanged (`verify`, + `Gitleaks`) → required-check contexts preserved. +- Job-level matrix with self-hosted label arrays is the standard Actions + pattern used across the fleet. +- No runtime gate or site logic touched; the repo's npm suite is unaffected.
