Import uses ESM; require uses CommonJS. Root modes use fresh sandboxes. Subpath batches share module caches and globals. Select a result to inspect its evidence.

Static manifest, native and script observations

Static indicators are context; their presence alone does not establish a prerequisite or failure.

Reproduce these inputs

Download both files, then run on a qualified Linux amd64/runsc host with the pinned images available. Rebuilding creates a new snapshot generation.

Reproduction inputs Exact package lock

compatlab reproduce ./d09824f9-dd88-46c0-91ba-b3893adbe576-reproduction.json --rebuild --lockfile ./package-lock.json --json

The original worker last reported its sealed snapshot as available. Verified reuse requires those actual bytes in your local state directory. Setup and replay limits

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.
