Evidence limitations
- Only installation and loading were observed; functional correctness and package safety are not established.
- Subpath batches share module caches and globals; root modes use separate fresh sandboxes.
- Package-visible harness observations can be tampered with. They are not adversarial attestation.
- Evidence applies to these exact artifacts, dependency snapshot, runtime images and Linux amd64/glibc policy.
- Runtime error codes are captured observations and can also be thrown by package code.
