description	Implement extension bridge mission parity, lifecycle visibility, operator actions, and reconnect safety.

NOTE: Startup and cleanup are handled by worker-base. This skill defines the work procedure.

When to Use This Skill

Use for extensions/openburnbar work: daemon bridge types/client/controller logic, projection/view-model updates, extension host integration, and mission parity in extension surfaces.

Required Skills

None.

Work Procedure

1. Confirm target assertion IDs and map required extension contract/state/view changes.
2. Add failing Vitest/extension-host tests first for bridge parity and reconnect behavior.
3. Implement bridge/client/state updates, preserving controller arbitration and session mismatch recovery semantics.
4. Validate mission parity fields (mission lifecycle, closure evidence, PR linkage, closure question state) when required.
5. Run extension checks:
   • npm --prefix extensions/openburnbar run test:unit -- test/controller.test.ts test/projections.test.ts test/workspacePanel.test.ts test/extension.test.ts
   • ./scripts/test-openburnbar-extension-host.sh
6. Include evidence showing daemon→extension projection convergence after mutating actions.

When to Return to Orchestrator

• Needed daemon mission contracts are unavailable or unstable for extension parity implementation.
• Extension-host environment cannot validate required integration behavior.
• Arbitration/session ownership semantics conflict with required mission operator actions.
