Preserve patch size metadata for local agent artifacts

[chubes4]

Summary

• Finalized Homeboy agent-task cook run recovery-homeboy-8118-empty-patch-size into review-ready branch fix/8118-opencode-empty-patch-size.

Proof provenance

• Proof runner: Homeboy agent-task cook loop
• Proof ID: agent-task-finalization:recovery-homeboy-8118-empty-patch-size
• Homeboy run ID: recovery-homeboy-8118-empty-patch-size
• Manual proof: none recorded by this Homeboy finalization

Publication intent

• Schema: homeboy/agent-task-publication-intent/v1
• Action: review_request
• Target kind: code_review
• Adapter: github_pull_request
• Base: main
• Head: fix/8118-opencode-empty-patch-size

Source refs

• Preserve patch size metadata for OpenCode no-op outcomes #8118

Source relationship

• Related finding ID: none recorded
• Source packet ID: none recorded
• Change kind: runtime-fix
• Supersedes: none recorded
• Depends on: none recorded

Runtime guardrails

• Why this is not broader than the packet evidence: Only canonical regular files under the Homeboy-owned artifact root are measured; foreign, inaccessible, directory, and escaping paths remain unknown.
• Evidence discriminators preserved: canonical Homeboy artifact root ownership
• Nearby contracts preserved: unknown foreign artifact paths remain review-only

Attempt summary

Homeboy-owned local artifact files are measured before aggregation; zero-byte patches become no-op while inaccessible artifacts remain conservatively unknown.
