From 902f3316f4a021b54cf6c0118818ec3beb9dbd33 Mon Sep 17 00:00:00 2001 From: Gabor Szabo <168316277+w7-mgfcode@users.noreply.github.com> Date: Sun, 1 Feb 2026 08:17:48 +0100 Subject: [PATCH 01/10] feat(registry): implement model registry for run tracking and deployments (#36) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * docs: expand INITIAL-7 with lifecycle, lineage, and artifact integrity details Co-Authored-By: Claude Opus 4.5 * feat(registry): implement model registry for run tracking and deployments Add model registry feature (PRP-7) with: - ORM models: ModelRun with JSONB columns (model_config, metrics, runtime_info), DeploymentAlias for mutable deployment pointers - Storage: LocalFSProvider with SHA-256 integrity verification and path traversal prevention, abstract interface for future S3/GCS support - Service: RegistryService with state machine validation, duplicate detection, config hashing, and run comparison - API endpoints: CRUD for runs and aliases, artifact verification, run comparison with config/metrics diffs - Database: Alembic migration with GIN indexes for JSONB containment queries - Tests: 103 unit tests (schemas, storage, service) + 24 integration tests - Example: registry_demo.py demonstrating full workflow Run lifecycle: PENDING → RUNNING → SUCCESS/FAILED → ARCHIVED Aliases can only point to SUCCESS runs for deployment safety. Co-Authored-By: Claude Opus 4.5 * docs: update documentation for model registry implementation - README.md: Add registry to project structure, API endpoints section, and example reference - docs/ARCHITECTURE.md: Update section 7.6 with full implementation details, add registry endpoints to section 8, mark Phase 1 complete - docs/PHASE-index.md: Mark phases 4-6 as completed, add detailed completion entries for Forecasting, Backtesting, and Registry Co-Authored-By: Claude Opus 4.5 * docs: add PHASE documentation for forecasting, backtesting, and registry Create missing phase documentation files to complete the project's implementation records: - 4-FORECASTING.md: Model zoo with BaseForecaster interface, train/predict endpoints, and joblib persistence - 5-BACKTESTING.md: Time-series CV with expanding/sliding strategies, metrics calculation, and baseline comparisons - 6-MODEL_REGISTRY.md: Run tracking with state machine, deployment aliases, and SHA-256 artifact integrity verification Update PHASE-index.md to link to the new documentation files. Co-Authored-By: Claude Opus 4.5 * fix(registry): resolve type checking issues with Pydantic model_config alias - Add pydantic.mypy plugin to pyproject.toml for proper Pydantic type checking - Use model_config_data instead of model_config alias in tests to avoid collision with Pydantic's reserved model_config attribute - Update _model_to_response to use model_validate() for proper alias handling - Change docker-compose postgres port to 5433 to avoid conflicts Co-Authored-By: Claude Opus 4.5 * fix: resolve CI failures for registry PR - Import registry models in alembic/env.py for schema validation - Fix import order and remove extraneous f-strings in registry_demo.py - Add type: ignore comments for frozen model tests with pydantic.mypy plugin Co-Authored-By: Claude Opus 4.5 * fix: prevent db_session fixtures from dropping all tables The data_platform and root conftest.py db_session fixtures were dropping all tables after each test, causing subsequent integration tests to fail when they couldn't find migrated tables. Changes: - Remove Base.metadata.drop_all from db_session fixtures - Tests now rely on migrations for table creation - Each test just rolls back its own changes Also fixes ruff format issue in examples/registry_demo.py. Co-Authored-By: Claude Opus 4.5 * fix: add proper test data cleanup to db_session fixtures Update data_platform and ingest test fixtures to clean up test data explicitly instead of dropping all tables or just rolling back. - data_platform: delete test stores, products, calendar entries - ingest: delete test stores, products, sales, calendar entries This ensures test isolation while preserving migrated tables. Co-Authored-By: Claude Opus 4.5 * fix: use separate session for test cleanup to avoid transaction issues When tests cause integrity errors, the session enters a failed state. Use a fresh session for cleanup to avoid PendingRollbackError. Co-Authored-By: Claude Opus 4.5 * fix: use contextlib.suppress instead of try-except-pass Replace try-except-pass patterns with contextlib.suppress to satisfy ruff S110 linting rule.

**DON'T** store absolute paths in artifact_uri — use relative paths +- **DON'T** skip state transition validation — corrupts run lifecycle +- **DON'T** allow aliases to non-SUCCESS runs — undefined behavior in production +- **DON'T** skip checksum verification on load — security risk +- **DON'T** use plain index on JSONB — use GIN for containment queries +- **DON'T** forget to compute config_hash — needed for deduplication +- **DON'T** hardcode storage paths — use Settings +- **DON'T** catch generic Exception — be specific about error types +- **DON'T** use sync operations in async context — will block event loop + +--- + +## Confidence Score: 8/10 + +**Strengths:** +- Clear patterns from forecasting and backtesting modules to follow +- Existing ModelBundle in persistence.py has

+- Integration with existing forecasting module needs coordination +- Duplicate detection edge cases (same config, different data windows) + +**Mitigation:** +- Start with simple GIN index, optimize later if needed +- Use explicit transition validation function +- Use database transactions for alias updates +- Add integration tests covering forecasting → registry flow +- Define clear duplicate

Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * chore: release v0.2.0 (#37) * feat(registry): implement model registry for run tracking and deployments (#36) * docs: expand INITIAL-7 with lifecycle, lineage, and artifact integrity details Co-Authored-By: Claude Opus 4.5 * feat(registry): implement model registry for run tracking and deployments Add model registry feature (PRP-7) with: - ORM models: ModelRun with JSONB columns (model_config, metrics, runtime_info), DeploymentAlias for mutable deployment pointers - Storage: LocalFSProvider with SHA-256 integrity verification and path traversal prevention, abstract interface for future S3/GCS support - Service: RegistryService with state machine validation, duplicate detection, config hashing, and run comparison - API endpoints: CRUD for runs and aliases, artifact verification, run comparison with config/metrics diffs - Database: Alembic migration with GIN indexes for JSONB containment queries - Tests: 103 unit tests (schemas, storage, service) + 24 integration tests - Example: registry_demo.py demonstrating full workflow Run lifecycle: PENDING → RUNNING → SUCCESS/FAILED → ARCHIVED Aliases can only point to SUCCESS runs for deployment safety. Co-Authored-By: Claude Opus 4.5 * docs: update documentation for model registry implementation - README.md: Add registry to project structure, API endpoints section, and example reference - docs/ARCHITECTURE.md: Update section 7.6 with full implementation details, add registry endpoints to section 8, mark Phase 1 complete - docs/PHASE-index.md: Mark phases 4-6 as completed, add detailed completion entries for Forecasting, Backtesting, and Registry Co-Authored-By: Claude Opus 4.5 * docs: add PHASE documentation for forecasting, backtesting, and registry Create missing phase documentation files to complete the project's implementation records: - 4-FORECASTING.md: Model zoo with BaseForecaster interface, train/predict endpoints, and joblib persistence - 5-BACKTESTING.md: Time-series CV with expanding/sliding strategies, metrics calculation, and baseline comparisons - 6-MODEL_REGISTRY.md: Run tracking with state machine, deployment aliases, and SHA-256 artifact integrity verification Update PHASE-index.md to link to the new documentation files. Co-Authored-By: Claude Opus 4.5 * fix(registry): resolve type checking issues with Pydantic model_config alias - Add pydantic.mypy plugin to pyproject.toml for proper Pydantic type checking - Use model_config_data instead of model_config alias in tests to avoid collision with Pydantic's reserved model_config attribute - Update _model_to_response to use model_validate() for proper alias handling - Change docker-compose postgres port to 5433 to avoid conflicts Co-Authored-By: Claude Opus 4.5 * fix: resolve CI failures for registry PR - Import registry models in alembic/env.py for schema validation - Fix import order and remove extraneous f-strings in registry_demo.py - Add type: ignore comments for frozen model tests with pydantic.mypy plugin Co-Authored-By: Claude Opus 4.5 * fix: prevent db_session fixtures from dropping all tables The data_platform and root conftest.py db_session fixtures were dropping all tables after each test, causing subsequent integration tests to fail when they couldn't find migrated tables. Changes: - Remove Base.metadata.drop_all from db_session fixtures - Tests now rely on migrations for table creation - Each test just rolls back its own changes Also fixes ruff format issue in examples/registry_demo.py. Co-Authored-By: Claude Opus 4.5 * fix: add proper test data cleanup to db_session fixtures Update data_platform and ingest test fixtures to clean up test data explicitly instead of dropping all tables or just rolling back. - data_platform: delete test stores, products, calendar entries - ingest: delete test stores, products, sales, calendar entries This ensures test isolation while preserving migrated tables. Co-Authored-By: Claude Opus 4.5 * fix: use separate session for test cleanup to avoid transaction issues When tests cause integrity errors, the session enters a failed state. Use a fresh session for cleanup to avoid PendingRollbackError. Co-Authored-By: Claude Opus 4.5 * fix: use contextlib.suppress instead of try-except-pass Replace try-except-pass patterns with contextlib.suppress to satisfy ruff S110 linting rule. Co-Authored-By: Claude Opus 4.5 --------- Co-authored-by: Gabe@w7dev Co-authored-by: Claude Opus 4.5 * fix: code improvements and documentation fixes - Add date range filter to SalesDaily cleanup in ingest tests - Enforce artifact_hash presence before verification in registry routes - Compute SHA256 from saved file instead of source in storage - Fix override_get_db to mirror production transaction semantics - Filter DeploymentAlias cleanup to only test runs - Update database port to 5433 in config and .env.example - Add language identifiers to fenced code blocks (MD040) - Fix table formatting for markdownlint MD060 - Update PR reference in PHASE/6-MODEL_REGISTRY.md - Convert bare URLs to markdown links in INITIAL-7.md - Wrap __init__.py in backticks in PRP-7 Co-Authored-By:

Async-ready job contracts prepare for background execution of long-running operations (training, backtesting) +- **RAG Integration**: OpenAPI export with rich descriptions enables high-quality function calling via embeddings + +--- + +## What + +### User-Visible Behavior + +1. **Dimension Discovery** + - `GET /dimensions/stores` - List all stores with metadata (code, name, region, type) + - `GET /dimensions/stores/{store_id}` - Get single store details + - `GET /dimensions/products` - List all products with metadata (sku, name, category, brand) + - `GET /dimensions/products/{product_id}` - Get single product details + - Supports filtering by region, category, brand with pagination + +2. **Data Analytics** + - `GET /analytics/kpis` - Aggregated KPIs (total revenue, units, by store/category/date) + - `GET /analytics/drilldowns` - Drill into KPIs by dimension (store, product, date range) + +3. **Job Orchestration (Async-Ready)** + - `POST /jobs` - Create new job (wraps train/predict/backtest) + - `GET /jobs/{job_id}` - Poll job status (PENDING | RUNNING | COMPLETED | FAILED) + - `GET /jobs` - List recent jobs with filtering + - `DELETE /jobs/{job_id}` - Cancel pending/running job + - Synchronous execution initially; contracts support future async migration + +4. **RFC 7807 Error Responses** + - All errors return structured Problem Details format + - Domain-specific error types (URIs) for each error category + - Instance URIs for error tracking/correlation + +5. **OpenAPI Export** + - `GET /openapi.json` - Standard OpenAPI 3.1 schema (already provided by FastAPI) + - `scripts/export_openapi.py` - Export enriched schema for RAG indexing + - All Field descriptions optimized for LLM tool selection + +### Success Criteria + +- [ ] Dimension discovery endpoints implemented with pagination and filtering +- [ ] KPI/drilldown endpoints with date range, store, product filters +- [ ] Job orchestration contracts defined (sync implementation) +- [ ] RFC 7807 ProblemDetail schema integrated with all error handlers +- [ ] All existing endpoints enhanced with rich Field descriptions +- [ ] OpenAPI export script produces RAG-ready documentation

48c7467c2d1624942d207d37c077d3a1f29f8b09 Mon Sep 17 00:00:00 2001 From: "Gabe@w7dev" Date: Sun, 1 Feb 2026 14:37:54 +0000 Subject: [PATCH 10/10] fix: address code review issues for RAG module and docs - Make migration deterministic by hardcoding dimension values instead of reading from environment (alembic migration) - Add pyyaml dependency for YAML parsing in OpenAPI chunker - Fix token count logging to capture original count before truncation - Add path traversal protection to RAG service _read_content_from_path (mirrors registry/storage.py pattern) - Fix markdown linting issues: - Add language tags to fenced code blocks (MD040) - Fix table pipe spacing (MD060) - Fix index_docs.py to treat 200 same as 201 for idempotent responses - Add test for path traversal protection
