# AGENTS - Scanner Gate Library

## Roles
- Backend engineer: .NET 10 gate policy, DI wiring, configuration, and determinism.
- QA / bench engineer: tests for policy evaluation, caching, audit logging, and config validation.

## Required Reading
- docs/README.md
- docs/07_HIGH_LEVEL_ARCHITECTURE.md
- docs/modules/platform/architecture-overview.md
- docs/modules/scanner/architecture.md
- src/Scanner/AGENTS.md
- Current sprint file under docs/implplan/SPRINT_*.md

## Working Directory & Boundaries
- Primary scope: src/Scanner/__Libraries/StellaOps.Scanner.Gate
- Test scope: src/Scanner/__Tests/StellaOps.Scanner.Gate.Tests (create if missing)
- Avoid cross-module edits unless explicitly allowed in the sprint file.

## Determinism and Safety
- Inject TimeProvider and IGuidGenerator; no DateTime.UtcNow or Guid.NewGuid in production code.
- Use InvariantCulture for parsing/formatting and stable ordering for rule evaluation.

## Testing
- Cover policy evaluation, options validation, caching behavior, and audit logging.
- Use deterministic fixtures and fixed time providers in tests.
