Notes

  • Gated by canStart in ark_detail.md.
  • Only the project initiator (project.initiatorUserId) can call this.
  • After starting, project.completesAt carries the finish time.

Live Verification

  • Not probed (POST is mutating and the 2026-08-26 sweep was read-only).
  • Path, verb and request body were extracted from the official game client bundle (/assets/*.js), so they match what the game itself sends. The response shape is inferred from how the client consumes the reply and is marked as such.
