## From README

Parallel session caveats Multi-repo workspace anchor: drop a .omc-workspace marker at the parent directory so multiple sessions across sub-repos share one .omc/. Resolution order: OMCSTATEDIR \> .omc-workspace \> git \> cwd. See docs/REFERENCE.md. Session id source: OMCSESSIONID env var wins in CLI contexts; hook payload data.sessionid wins in hook contexts. Plan id (when applicable): Ultrawork has no persistent state; two concurrent runs are independent by design. No plan-id needed. Parallel verdict: supported (stateless component) Relationship to Other Modes Ultrawork is the parallelism layer. Ralph adds persistence and verification. Autopilot adds the full lifecycle pipeline.
