Implement three-stage execution lifecycle with idempotent runs and complete
provenance tracking via RunManifest.
Core Features:
- PromptRun model with execution lifecycle stages:
1. Analysis: Template analysis and macro extraction
2. Compilation: Macro resolution and context compilation
3. Processing: LLM execution and output generation
- InputBundleHash for deterministic idempotency (FR-4.3)
- RunManifest for complete execution provenance (FR-5)
- LLMAdapter interface for pluggable model providers
- MockLLMAdapter for testing without API calls
- PromptExecutionEngine orchestrating full lifecycle
Idempotent Execution (FR-4.4):
- Calculate SHA-256 hash of complete input context
- Skip execution if identical hash exists
- Cache successful runs by hash
- Support force re-execution via config flag
RunManifest Tracking (FR-5.2):
- Template metadata (id, name, digest)
- Resolved input artifacts and digests
- Compiled prompt digest
- Model configuration
- Output artifacts
- Dependency edges for graph construction
- Timing metadata for performance analysis
Tests (27 passing):
- 17 execution model tests (config, bundle, runs, stages)
- 10 engine tests (execution, idempotency, errors, caching)
Implements:
- FR-4.1: Three-stage execution lifecycle
- FR-4.2: CompiledPrompt during compilation
- FR-4.3: InputBundleHash calculation
- FR-4.4: Skip execution for identical hashes
- FR-5.1: RunManifest persistence
- FR-5.2: Complete manifest contents
- FR-5.3: Nested run linking (foundation)
