Proposal: Canton CRO - Party/Participant Recovery Orchestration

Development Fund Proposal Submission

Proposal file: /proposals/2026-07-CantonCRO-recovery-orchestration.md

---

Summary

Canton CRO is an open-source CLI that turns the documented 13-step party/participant recovery procedure into a safe, repeatable, provable operation: plan, live preflight, apply, resume, and recovery drills. This is a working tool, not a design proposal: all 13 steps run against real Canton 3.5.8, and a real broken-import recovery drill (genuine Canton error, safe stop, restore, resume) runs in CI on every push.
