Optional dispatch_allow bool (default false). When true, inject a .dispatch-allow file at repo root on the resolved default branch after substitution, marking the new project dispatch-eligible (dispatch#3) without a manual follow-up commit. Rides the existing upsertRetry path so injection inherits the infra#179 branch-readiness / partial_failure handling; a stalled injection degrades exactly like substitution. Reported in files_substituted. false/omitted is byte-for-byte unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
