From 415eff120750beea9b423770cd59f0d7772e794e Mon Sep 17 00:00:00 2001 From: master <> Date: Tue, 16 Dec 2025 14:00:35 +0200 Subject: [PATCH] feat(metrics): Implement scan metrics repository and PostgreSQL integration - Added IScanMetricsRepository interface for scan metrics persistence and retrieval. - Implemented PostgresScanMetricsRepository for PostgreSQL database interactions, including methods for saving and retrieving scan metrics and execution phases. - Introduced methods for obtaining TTE statistics and recent scans for tenants. - Implemented deletion of old metrics for retention purposes. test(tests): Add SCA Failure Catalogue tests for FC6-FC10 - Created ScaCatalogueDeterminismTests to validate determinism properties of SCA Failure Catalogue fixtures. - Developed ScaFailureCatalogueTests to ensure correct handling of specific failure modes in the scanner. - Included tests for manifest validation, file existence, and expected findings across multiple failure cases. feat(telemetry): Integrate scan completion metrics into the pipeline - Introduced IScanCompletionMetricsIntegration interface and ScanCompletionMetricsIntegration class to record metrics upon scan completion. - Implemented proof coverage and TTE metrics recording with logging for scan completion summaries. --- .gitea/workflows/build-test-deploy.yml | 65 +++ README.md | 5 + docs/db/RULES.md | 44 ++ docs/db/SPECIFICATION.md | 61 +++ docs/db/schemas/scan-metrics.md | 195 ++++++++ ...0_0001_0001_ci_quality_gates_foundation.md | 10 +- ...1_0001_sca_failure_catalogue_completion.md | 4 +- ..._0001_proof_chain_content_addressed_ids.md | 28 +- ...01_0001_determinism_scoring_foundations.md | 6 +- .../SPRINT_3406_0001_0001_metrics_tables.md | 19 +- ...SPRINT_3423_0001_0001_generated_columns.md | 4 +- docs/testing/ci-quality-gates.md | 155 ++++++ .../ContentAddressedIdGeneratorTests.cs | 302 ++++++++++++ .../ContentAddressedIdTests.cs | 231 +++++++++ .../JsonCanonicalizerTests.cs | 224 +++++++++ .../MerkleTreeBuilderTests.cs | 170 +++++++ .../Scoring/FreshnessAwareScoringService.cs | 129 +++++ .../DeterminismScoringIntegrationTests.cs | 172 +++++++ .../Metrics/ScanMetricsCollector.cs | 321 +++++++++++++ .../Models/ScanMetricsModels.cs | 173 +++++++ .../Postgres/Migrations/004_scan_metrics.sql | 208 ++++++++ .../Postgres/Migrations/MigrationIds.cs | 1 + .../Repositories/IScanMetricsRepository.cs | 85 ++++ .../PostgresScanMetricsRepository.cs | 445 ++++++++++++++++++ .../Fixtures/ScaCatalogueDeterminismTests.cs | 192 ++++++++ .../Fixtures/ScaFailureCatalogueTests.cs | 295 ++++++++++++ .../ScanCompletionMetricsIntegration.cs | 111 +++++ 27 files changed, 3620 insertions(+), 35 deletions(-) create mode 100644 docs/db/schemas/scan-metrics.md create mode 100644 docs/testing/ci-quality-gates.md create mode 100644 src/Attestor/__Tests/StellaOps.Attestor.ProofChain.Tests/ContentAddressedIdGeneratorTests.cs create mode 100644 src/Attestor/__Tests/StellaOps.Attestor.ProofChain.Tests/ContentAddressedIdTests.cs create mode 100644 src/Attestor/__Tests/StellaOps.Attestor.ProofChain.Tests/JsonCanonicalizerTests.cs create mode 100644 src/Attestor/__Tests/StellaOps.Attestor.ProofChain.Tests/MerkleTreeBuilderTests.cs create mode 100644 src/Policy/__Libraries/StellaOps.Policy/Scoring/FreshnessAwareScoringService.cs create mode 100644 src/Policy/__Tests/StellaOps.Policy.Scoring.Tests/DeterminismScoringIntegrationTests.cs create mode 100644 src/Scanner/StellaOps.Scanner.Worker/Metrics/ScanMetricsCollector.cs create mode 100644 src/Scanner/__Libraries/StellaOps.Scanner.Storage/Models/ScanMetricsModels.cs create mode 100644 src/Scanner/__Libraries/StellaOps.Scanner.Storage/Postgres/Migrations/004_scan_metrics.sql create mode 100644 src/Scanner/__Libraries/StellaOps.Scanner.Storage/Repositories/IScanMetricsRepository.cs create mode 100644 src/Scanner/__Libraries/StellaOps.Scanner.Storage/Repositories/PostgresScanMetricsRepository.cs create mode 100644 src/Scanner/__Tests/StellaOps.Scanner.Core.Tests/Fixtures/ScaCatalogueDeterminismTests.cs create mode 100644 src/Scanner/__Tests/StellaOps.Scanner.Core.Tests/Fixtures/ScaFailureCatalogueTests.cs create mode 100644 src/Telemetry/StellaOps.Telemetry.Core/StellaOps.Telemetry.Core/ScanCompletionMetricsIntegration.cs diff --git a/.gitea/workflows/build-test-deploy.yml b/.gitea/workflows/build-test-deploy.yml index 461935318..b37caf944 100644 --- a/.gitea/workflows/build-test-deploy.yml +++ b/.gitea/workflows/build-test-deploy.yml @@ -575,6 +575,71 @@ PY if-no-files-found: ignore retention-days: 7 + # ============================================================================ + # Quality Gates Foundation (Sprint 0350) + # ============================================================================ + quality-gates: + runs-on: ubuntu-22.04 + needs: build-test + permissions: + contents: read + steps: + -
