# Pack Run Approval Gates

## Module
TaskRunner

## Status
IMPLEMENTED

## Description
Approval gate system for task packs with coordinator, decision service, state tracking, and gate state updating.

## Implementation Details
- **Approval coordinator**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Core/Execution/PackRunApprovalCoordinator.cs` -- orchestrates approval gate flow
- **Approval state**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Core/Execution/PackRunApprovalState.cs` -- approval state tracking model
- **Approval status**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Core/Execution/PackRunApprovalStatus.cs` -- approval status enum
- **Approval store interface**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Core/Execution/IPackRunApprovalStore.cs` -- approval persistence contract
- **Gate state updater**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Core/Execution/PackRunGateStateUpdater.cs` -- updates gate states during execution
- **Decision service**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Infrastructure/Execution/PackRunApprovalDecisionService.cs` -- processes approval decisions
- **File-based store**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Infrastructure/Execution/FilePackRunApprovalStore.cs` -- file-backed approval persistence
- **Postgres store**: `src/TaskRunner/__Libraries/StellaOps.TaskRunner.Persistence/Postgres/Repositories/PostgresPackRunApprovalStore.cs` -- PostgreSQL approval persistence
- **Tests**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Tests/PackRunApprovalCoordinatorTests.cs`, `PackRunApprovalDecisionServiceTests.cs`, `PackRunGateStateUpdaterTests.cs`
- **Source**: Feature matrix scan

## E2E Test Plan
- [ ] Verify approval gates block execution until approved
- [ ] Test approval coordinator handles multi-approver gates
- [ ] Verify gate state transitions (pending -> approved/rejected)
- [ ] Test approval persistence survives service restart
- [ ] Verify rejected gates prevent pack run continuation
