# GroundTruth.Reproducible - Agent Instructions
## Module Overview
This library supports reproducible build verification, rebuild execution, and
determinism validation for binary artifacts.
## Key Components
- **RebuildService** - Orchestrates reproducibility verification runs.
- **IRebuildService** - Abstraction for rebuild operations.
- **LocalRebuildBackend** - Local rebuild execution backend.
- **ReproduceDebianClient** - Debian reproducible build helper.
- **DeterminismValidator** - Compares outputs for deterministic builds.
- **SymbolExtractor** - Extracts symbols for diff analysis.
- **AirGapRebuildBundle** - Offline bundle input for rebuilds.
## Required Reading
- `docs/README.md`
- `docs/07_HIGH_LEVEL_ARCHITECTURE.md`
- `docs/modules/platform/architecture-overview.md`
## Working Agreement
- Keep output deterministic (stable ordering, UTC timestamps).
- Avoid new external network calls; honor offline-first posture.
- Update sprint status and document any cross-module touches.
