A this-invocation output.md is preserved and never retried over, but
Success=false stays a step failure so truncated writes cannot pass.
Prior-round residue without a trusted patch is also not success.

Fresh step invocation is limited to provider terminated/connection plus
a missing target, or an explicit runner failure. A deliverable already
on disk is accepted and never overwritten.

Treat process-0 plus terminated/Connection error/auto_retry_end as a
provider transient. Permanent missing deliverables stay fail-closed and
are never reconstructed from truncated write arguments.
