+# CRG Grade C Test Coverage
+
+**Repository:** a2ml-showcase  
+**Grade:** C  
+**Last Updated:** 2026-04-04
+
+## Overview
+
+This repository contains A2ML showcase examples and documentation. As a data/showcase repository with no executable code, tests focus on:
+- Valid A2ML example structure
+- Consistency of formatting
+- Completeness of required fields
+- Documentation accuracy
+
+## Test Categories
+
+| Category | Count | Status | Notes |
+|----------|-------|--------|-------|
+| Unit Tests | 4 | ✓ PASS | File existence, structure, SPDX headers, content files |
+| Smoke Tests | 3 | ✓ PASS | A2ML syntax, attestation blocks, policy blocks |
+| Contract Tests | 2 | ✓ PASS | Required A2ML fields, valid trust levels |
+| Aspect Tests | 3 | ✓ PASS | Agent naming, formatting consistency, SPDX consistency |
+| Property-Based Tests | 2 | ✓ PASS | Agent-id declarations, trust level progression |
+| E2E/Reflexive Tests | 2 | ✓ PASS | Attestation parsing, reference resolution |
+| Benchmarks | 2 | ✓ PASS | File read performance, example count baseline |
+
+**Total Test Count:** 18  
+**All Tests Passing:** Yes
+
+## Running Tests
+
+```bash
+deno test tests/validate.test.ts
+```
+
+## Test Details
+
+### Unit Tests (4)
+- Validates all required example files exist
+- Checks for SPDX license headers in examples
+- Verifies content structure has expected sections
+- Confirms markdown files are readable
+
+### Smoke Tests (3)
+- Verifies @attestation blocks are syntactically valid
+- Checks @policy blocks are present and formatted
+- Validates README cross-references
+
+### Contract Tests (2)
+- Every attestation must have: agent-id, attested-by, trust-level
+- Trust levels must be one of: self-declared, verified, audited
+
+### Aspect Tests (3)
+- Agent IDs follow naming convention (lowercase-alphanumeric-hyphens)
+- @attestation/@end blocks are balanced
+- SPDX headers are consistent across documentation
+
+### Property-Based Tests (2)
+- Every declared agent-id must appear in at least one attestation
+- Documentation includes all three trust level progression stages
+
+### E2E/Reflexive Tests (2)
+- A2ML attestation blocks can be parsed into key-value pairs
+- All numbered references [1], [2], etc. are cited in text
+
+### Benchmarks (2)
+- File read operations complete in < 100ms
+- Contains expected number of documented examples (≥ 3)
+
+## Dependencies
+
+- Deno 1.40+
+- deno_std (assert module)
+
+## Future Enhancements
+
+- [ ] Add schema validation against formal A2ML grammar
+- [ ] Validate agent capabilities against registry
+- [ ] Check timestamp formats (RFC3339)
+- [ ] Verify signature formats
