Four new caches in wasm-build.yml, keyed on their real inputs:
- Binaryen post-process tools (bin/ only, keyed on the submodule SHA): on a
hit BINARYEN_TRUST_PREBUILT=1 tells build-wasm-opt.sh to skip cmake+ninja
and trust the restored binaries (~46s/run). The guard is env-gated so local
pass iteration (uncommitted sources, same SHA) is unaffected.
- Built wx test apps (tests/apps minus kicad/ staging + gal-webgl/): skips
the whole build step on a hit (~3 min — the post-link hoist+asyncify over
~74 apps dominates). Key covers wx SHA + kicad SHA (some apps compile real
KiCad sources: thread_pool.cpp, libcontext), binaryen SHA, tracked app
sources, and the build/post-link scripts + shims. Gated on a wx cache HIT:
the app build creates the libwx_*.a symlinks the GAL link needs, so on a
wx rebuild the apps must rebuild too.
- Host emsdk (tools/emsdk, keyed on the pinned EMSCRIPTEN_VERSION): mostly
availability insurance — a fresh install is only ~23s but pulls ~340 MB
from github.com + storage.googleapis.com on every run. downloads/ tarballs
are pruned before the post-job save.
- Playwright browsers (~/.cache/ms-playwright keyed on tests/package-lock).
Warm-cache runs should drop from ~12 min to ~8-8.5 min (e2e suites are the
floor). Measured baselines from runs 28577824366 / 28520845242.
