Description
Foundry release downloads are normally fast, but transient GitHub release-asset failures have been causing E2E and benchmark jobs to fail. The previous
.metamaskActions cache was removed in #43868 because a normalyarn mm-foundryupinstallation usually takes only 1–2 seconds, while restoring the cache on every job added coupling, cache usage, and workflow complexity.This PR keeps that fast direct-download path and adds the cache back strictly as a fallback:
package.jsonbefore executing it.The cache key includes the schema version, platform, architecture, installed
@metamask/foundryupversion, Foundry version, and expected Anvil checksum. A single best-effort step in the trustedmainprep-depsjob maintains the cache using a lookup-only restore; parallel E2E, benchmark, and fixture-update jobs are restore-only consumers and never contend to write it.The shared behavior lives in a local composite action used by all three workflows. It deliberately does not race cache restoration against
foundryup, avoiding concurrent writes to.metamaskand first-success/cancellation coordination.Changelog
