Illustrative local event factory, not live GitHub, AI agents or a repository integration. Twenty-four identities are 12 request IDs × two revisions, treated as independent logical jobs. The dedup ledger lasts for the whole saved session. FIFO follows first arrival. A chosen fixed-hour policy admits at most 12 actual worker starts; queueing and duplicate signals use no wake. Next hour explicitly resets only this counter. Three physical desks take at most the selected capacity; reducing capacity lets in-flight jobs finish before new admission. Two explicit work ticks complete a job; visual cycles are scaled to four seconds and do not change work state. Approval represents a human review and passing checks; integration is an explicit local operation. Authentication, payload validation, network retries, branch-head supersession, durable transactions and real provider limits are outside this model.
