The single matrix job becomes two independent jobs on the oak Gitea
runners (oak-ubuntu-2404 / oak-windows-2025 — the user's labels, kept
as-is). Every runner.os conditional collapses into the owning job and
all macOS steps are removed. actionlint.yaml whitelists the two oak
runner labels (actionlint needs -config-file now that the config lives
under .gitea/ instead of the default .github/ path).
Gitea prep: .github becomes .gitea (the act runner looks there), and
every actions/cache + Swatinem/rust-cache step is commented out until
the self-hosted instance has a cache provisioned. The remaining
marketplace actions (checkout/upload-artifact are act-compatible;
msys2/setup-msys2, dtolnay/rust-toolchain and softprops/action-gh-release
need a runner test / replacement) are a follow-up.
tests: the two gpui keystroke tests that flaked on Windows CI (undo
pair, snapping toggle — each once, values identical to the pass state,
Global-route keys) now dispatch each key with a double park. The root
cause is not fully pinned: the loss happens inside gpui's synthetic
key dispatch on Windows (both tests hold every test lock; production
is unaffected). The CI retry-once remains the backstop. The earlier
idea of advancing the simulated clock to flush gpui's pending-input
timer is off the table: the mock engine's playback ticks with executor
time, so a clock advance moves the playhead out from under the
assertions (observed: playhead 14 vs expected 9).
