v0.18.2

Added

• Paid benchmark cells now persist provider-completion checkpoints and support verifier-only replay from the exact retained provider patch without another provider call.

Changed

• Benchmark progress now reports the active environment, provider, or verifier phase with elapsed time and its effective timeout.
• Benchmark cancellation gives Pier a bounded graceful-cleanup window before process-group escalation.

Fixed

• Provider streams and patches survive verifier failures, cancellation, cleanup errors, and artifact-promotion failures; failed promotion retains and reports its staging path.
• Linux cleanup repairs verifier-owned logs for running and stopped containers before removal, including root ownership repair through a temporary container when needed.
• Failed verifier replays retain their checkpoint and staging evidence instead of becoming resumable paid failures, while sanitization preserves a byte-exact private replay patch.
