-The `brew trust` step is Homebrew's tap-trust gate: dependencies from
-third-party taps stay refused until their tap is trusted once, and
-ecrou's engine, libkrun, ships from libkrun's own tap. The macOS
-build loads libkrun from that tap at runtime and boots through
-Hypervisor.framework; the formula signs the binary with the
-hypervisor entitlement macOS requires, so the install needs no extra
-steps. Building from source instead:
-
-```
-brew install libkrun/homebrew-krun/libkrun e2fsprogs libarchive
-cargo build --release -p ecrou-cli
-codesign --force --sign - --entitlements packaging/homebrew/ecrou.entitlements \
-  target/release/ecrou
-```
-
-Every local build needs that last line: cargo output is ad-hoc signed
-without the entitlement, and macOS refuses VM creation to it — `ecrou
-probe` says so and prints the command.
