Jeremie Fraeys 3248279c01 refactor: Phase 3 - Extract data integrity layer ... Created integrity package with extracted data utilities: 1. internal/worker/integrity/hash.go (113 lines) - FileSHA256Hex() - SHA256 hash of single file - NormalizeSHA256ChecksumHex() - Checksum normalization - DirOverallSHA256Hex() - Directory hash (sequential) - DirOverallSHA256HexParallel() - Directory hash (parallel workers) 2. internal/worker/integrity/validate.go (76 lines) - DatasetVerifier type for dataset validation - VerifyDatasetSpecs() method for checksum validation - ProvenanceCalculator type for provenance computation - ComputeProvenance() method for task provenance Note: Used 'integrity' instead of 'data' due to .gitignore conflict (data/ directory is ignored for experiment artifacts) Functions extracted from data_integrity.go: - fileSHA256Hex → FileSHA256Hex - normalizeSHA256ChecksumHex → NormalizeSHA256ChecksumHex - dirOverallSHA256HexGo → DirOverallSHA256Hex - dirOverallSHA256HexParallel → DirOverallSHA256HexParallel - verifyDatasetSpecs logic → DatasetVerifier - computeTaskProvenance logic → ProvenanceCalculator Build status: Compiles successfully		2026-02-17 14:20:41 -05:00
