Verdict

attempt_result: BLOCKED_WITH_EXACT_REPO_GAP
agent_behavior: PASS_CORRECT
production_mutation: NONE
root_cause: branch_precondition_reversed
actual_main_HEAD: 3d26a09
actual_feature_HEAD: 4649423
execution_enabled: false
next_effort: medium

The agent correctly did not run the planned merge because the live repo state contradicted the expected precondition. This is not a code defect and not a production issue. It means main already contains O3, while the feature branch is one commit behind main.

Accepted observed state

expected:
  main: 4649423
  feature: 3d26a09
observed:
  main: 3d26a09
  feature: 4649423
relationship:
  feature_is_ancestor_of_main: true
  main_is_ancestor_of_feature: false
  feature_to_main_count: 1
  main_to_feature_count: 0
safety:
  milestone: O3
  execution_enabled: false

Ruling

selected_next: SYNC_FEATURE_TO_MAIN_O3
reason:
  - main already has the desired O3 commit
  - feature branch is stale by one commit
  - synchronize feature to main by ff-only merge or checkout/reset only if safe
  - no production mutation involved

Preferred operation: fast-forward feature/constitution-snapshot-mark-dryrun to main@3d26a09, not merge main again.

Boundaries

forbidden:
  - production mutation
  - live orchestrator execution
  - enabling execution kill-switch
  - deploy/restart
  - push/tag remote
  - rewrite history unless explicitly proven safe and approved
  - non-ff merge

Final status

status: MAIN_ALREADY_O3__FEATURE_STALE__SYNC_FEATURE_NEXT
next_action: run_medium_feature_sync_to_main_O3
