| # CI tiers per SPEC §10. This is tier 1 (smoke: renders + non-black canvas). | |
| # Key facts (research/webgpu-ci-github.md): WebGPU works on free runners via | |
| # SwiftShader Vulkan, BUT headless Chrome never presents the WebGPU canvas on | |
| # Linux — tests must run HEADED under Xvfb (playwright.config.ts handles the | |
| # headless:false + SwiftShader flags when platform is linux). | |
| # Sharding: add a matrix over --shard=N/M when the corpus outgrows one runner. | |

| # corpus scale (software raster, 95 examples) — far too slow to sit on every | |
| # push during the porting phase. Metal-local is the oracle (SPEC §10); CI is | |
| # the regression net, and once nightly is enough for that. | |

| # NOT on push (porting-phase policy, 2026-07-28): ~30 min per run at corpus | |
| # scale is too slow to gate a push-per-pair cadence, and every port is already | |
| # verified on Metal locally (smoke + animates + contact sheet) before it lands. | |
| # Runs on PRs, nightly, and on demand (`gh workflow run ci.yml`). Revisit when | |
| # the corpus is complete and pushes drop to a few a month — then per-push is | |
| # cheap insurance again. | |
| # BLOCKING when it does run: the B17 repair resolved the SwiftShader stall | |
| # matrix (run 30261064018). Exceptions: per-example `ciSkip` in examples.json. | |
