The formula's url pointed at the tag's source archive while its sha256 came from the darwin tarball — two files, one checksum, so brew refused every install. The formula now pours the darwin tarball itself: the release workflow attaches it to the GitHub release, the tap formula pins that asset's real sha256, and installs stop compiling rust (the CI-signed entitlement also survives, which a source build would have stripped).

The binary is ad-hoc signed with the com.apple.security.hypervisor
|
|
entitlement. Rebuilding from source (cargo) requires re-signing:
|
|
codesign --force --sign - --entitlements packaging/homebrew/ecrou.entitlements target/release/ecrou
|
|
`ecrou probe` reports this when the entitlement is missing.
