# TaskPack Manifest and Planning

## Module
TaskRunner

## Status
IMPLEMENTED

## Description
Full task pack manifest system with loading, validation, planning, and plan hashing for deterministic execution verification.

## Implementation Details
- **Manifest model**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Core/TaskPacks/TaskPackManifest.cs` -- task pack manifest schema
- **Manifest loader**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Core/TaskPacks/TaskPackManifestLoader.cs` -- loads manifests from filesystem/storage
- **Manifest validator**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Core/TaskPacks/TaskPackManifestValidator.cs` -- validates manifest structure and constraints
- **Planner**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Core/Planning/TaskPackPlanner.cs` -- creates execution plans from manifests
- **Plan model**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Core/Planning/TaskPackPlan.cs` -- execution plan data model
- **Plan hasher**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Core/Planning/TaskPackPlanHasher.cs` -- deterministic plan hashing for verification
- **Plan insights**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Core/Planning/TaskPackPlanInsights.cs` -- planning insights and analysis
- **Expressions**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Core/Expressions/TaskPackExpressions.cs` -- expression evaluation for manifest conditions
- **Canonical JSON**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Core/Serialization/CanonicalJson.cs` -- deterministic JSON serialization for plan hashing
- **Tests**: `src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Tests/TaskPackPlannerTests.cs`, `TestManifests.cs`, `TestManifests.Egress.cs`
- **Source**: Feature matrix scan

## E2E Test Plan
- [ ] Verify manifest loading from filesystem
- [ ] Test manifest validation catches invalid structures
- [ ] Verify planner creates correct execution plans from manifests
- [ ] Test deterministic plan hashing produces consistent hashes
- [ ] Verify expression evaluation in manifest conditions
