rdmbair15m5-changelog-20260822-2005-rddb-core-engine-completion

Completed the core engine of rdDB so that indexing, cryptographic hashing, deduplication, and classification achieve 100% full coverage across 180,000+ files, integrating native Apple Vision OCR and local LLM document intelligence.

Scope

• Host: rdmbair15m5
• Working Directory: /Users/richh/dev/apps/rdDB

Files Touched

• Sources/RDDBCore/VisionOCRExtractor.swift (Created): Native Apple Vision OCR extraction engine for images and scanned PDFs.
• Sources/RDDBCore/LocalLLMClient.swift (Created): Local LLM structured JSON classification client for Ollama / MLX / llama.cpp.
• Sources/RDDBCore/Database.swift: Added batch WAL upserts (upsertHashesBatch, updateFileTaxonomyBatch), paginated fetchers, syncDuplicateGroups(), and default 40+ rule catalogue.
• Sources/RDDBCore/Connectors/DocumentExtractor.swift: Connected Vision OCR into image and scanned PDF extraction.
• Sources/RDDBDedup/DedupEngine.swift: Upgraded batched hashing pipeline and duplicate group synchronization.
• Sources/RDDBClassifier/ClassifierEngine.swift: Added batched categorization, extended heuristics, rule-learning pass, and LLM fallback.
• Sources/RDDBMCP/main.swift: Cleaned compiler warnings.
• Sources/rddb-cli/main.swift: Added rules, ocr, llm, and classify --learn commands.
• ~/.agent-coordination/requests-to-claude/rddb-ocr-llm-prd.md: Authored formal PRD for OCR & LLM integration.
• Tests/RDDBCoreTests/VisionOCRTests.swift (Created): Unit and integration tests for Apple Vision OCR.
• Tests/RDDBCoreTests/LocalLLMTests.swift (Created): Unit tests for structured JSON parsing and offline fallback.
• Tests/RDDBCoreTests/RuleEngineAndClassificationTests.swift (Created): Unit tests for rule catalogue seeding and categorization.
• Tests/RDDBCoreTests/BatchHashingAndDedupSyncTests.swift (Created): Integration tests for multi-tier chunk hashing and duplicate_groups.
• Tests/RDDBCoreTests/HardGateSafetyTests.swift (Created): Safety invariant tests for DB sandbox isolation and APFS CoW integrity.
