 # Implementation Plan
 
-- [ ] 1. Foundation: wire protocol schema and shared reconciliation types
+- [x] 1. Foundation: wire protocol schema and shared reconciliation types
 - [x] 1.1 Define the wire protocol for the reconciliation exchange
   - Add the controller→worker job-state query and worker→controller job-state report as new opcodes, each carrying a paginated list of per-job entries (job ID, status, exit code, worker-reported finish time, and whether the job was part of the original query)
   - Add the two new cluster-wide configuration fields: the recently-finished reporting window and the reconciliation timeout
