Each layer builds on previous layers with increasing validation complexity and execution time. + +### Layer 1: Schema Validation (Fast Path - ~50ms) + +**Purpose**: Verify snapshot JSON structure matches Pydantic model schema + +**Key Checks**: +- JSON serialization/deserialization roundtrip (validates all fields preserve values) +- All required fields present and correctly typed +- No unexpected extra fields in JSON +- UUID, datetime, and enum fields deserialize correctly + +**Validation Functions**: +- `SnapshotValidator.validate_layer_1_schema()` → `ValidationResult` +- `RepoStateSnapshot.model_validate_json()` (Pydantic validation) + +**Expected Duration**: ~40-80ms +**Failure Category**: STRUCTURAL (non-retryable) +**Use Case**: Pre-flight validation for malformed snapshots + +**Integration Test Coverage**: +- `tests/integration/observer/test_snapshot_validation.py::TestSnapshotSchemaValidation` (4 tests) +- Minimal snapshot schema validation +- Roundtrip serialization integrity +- All required fields presence verification +- Error snapshot handling + +### Layer 2: Completeness Validation (Fast Path - ~20ms) + +**Purpose**: Verify snapshot contains required signals and acceptable error thresholds + +**Key Checks**: +- Required signals present (test_signal, dependency_drift, lint_signal) +- At least 3 non-unavailable signals (test, dependency, lint, type, todo, coverage) +- Acceptable collector error count (≤5 errors allowed) +- Signal status fields properly populated + +**Validation Functions**: +- `SnapshotValidator.validate_layer_2_completeness()` → `ValidationResult` +- Signal presence checks: `signals.test_signal is not None` +- Signal status enumeration: "passing", "unavailable", "failing" +- Collector error counting: `len(snapshot.collector_errors) <= 5` + +**Expected Duration**: ~15-30ms +**Failure Category**: STRUCTURAL or TRANSIENT (>5 errors are retryable) +**Use Case**: Detect missing critical signal collectors, excessive collection failures + +**Integration Test Coverage**: +- `TestSnapshotCompletenessValidation` (8 tests) +- Minimal snapshot completeness +- Three-signal minimum requirement +- Limited signal detection +- Unavailable signal handling +- Collector error tolerance + +### Layer 3: Consistency Validation (Moderate Speed - ~50ms) + +**Purpose**: Cross-signal semantic checks ensuring signal values align with status + +**Key Checks**: +- Test signal consistency: If status="passing", then test_count > 0 +- Lint signal consistency: If violation_count > 100, status must be "violations"/"failing" +- Dependency consistency: If status="healthy", then critical_issues == 0 +- Coverage consistency: If total_coverage_pct > 0, coverage data must be present + +**Validation Functions**: +- `SnapshotValidator.validate_layer_3_consistency()` → `ValidationResult` +- Field extraction: `getattr(signal, 'field_name', None)` +- Status-value correlation: comparing enum values with numeric metrics +- Cross-signal validation without external system calls + +**Expected Duration**: ~40-70ms +**Failure Category**: STRUCTURAL (semantic contradiction indicates snapshot error) +**Use Case**: Detect invalid snapshot data created by faulty collection + +**Integration Test Coverage**: +- `TestSnapshotConsistencyValidation` (7 tests) +- Test signal count consistency +- Lint violation status consistency +- Dependency health consistency +- Coverage presence consistency +- Invalid snapshot detection + +### Layer 4: Real-World Accuracy Validation (Slow - 5-30s) + +**Purpose**: Compare snapshot values against actual live tools, with configurable tolerance + +**Key Checks**: +- Test count accuracy: `actual_count ≈ snapshot_count` (within tolerance) +- Coverage accuracy: `actual_coverage ≈ snapshot_coverage` (within tolerance) +- Lint violation count: Compares `ruff check` output count +- External tool execution: pytest, ruff, coverage.py + +**Validation Functions**: +- `SnapshotValidator.validate_layer_4_accuracy(tolerance)` → `ValidationResult` + - `_get_actual_test_count()` → runs pytest --collect-only + - `_get_actual_coverage()` → runs coverage report + - `_get_actual_lint_violations()` → runs ruff check + - Relative error calculation: `abs(actual - expected) / expected` + - Tolerance comparison: `relative_error <= tolerance` + +**Expected Duration**: 5-30s (depends on repo size and tool complexity) +**Failure Category**: TRANSIENT (actual system state may differ from snapshot time) +**Use Case**: Validate snapshots reflect real system state within margin of error +**Configuration**: +- Default tolerance: test_count=1%, coverage=5% +- Customizable per-metric tolerance +- Timeout: 60s default (configurable) + +**Integration Test Coverage**: +- `TestSnapshotAccuracyValidation` (6 tests) +- Test count accuracy within tolerance +- Coverage accuracy verification +- Lint violation count matching +- Timeout
