2.0.0 - 2025-10-22

🎉 Specimen-Centric Provenance Architecture

Major Achievement: Fundamental architectural shift from image-centric to specimen-centric data model, enabling full lineage tracking and production-scale data quality management.

Added - Specimen Provenance System

• 🔬 Specimen Index (src/provenance/specimen_index.py)
• SQLite database tracking specimens through transformations and extraction runs
• Automatic deduplication at (image_sha256, extraction_params) level
• Multi-extraction aggregation per specimen for improved candidate fields
• Data quality flagging: catalog duplicates, malformed numbers, missing fields

• Full audit trail from original camera files to published DwC records

• 📊 Deduplication Logic

• Deterministic: same (image, params) = cached result, no redundant processing
• Intentional re-processing supported: different params aggregate to better candidates
• Prevents waste: identified 2,885 specimens extracted twice (5,770 → 2,885)

• Cost savings: eliminates duplicate API calls and processing time

• 🏗️ Specimen-Centric Data Model

• Specimen identity preserved through image transformations
• Provenance DAG: original files → transformations → extractions → review
• Content-addressed images linked to specimen records

• Support for multiple source formats per specimen (JPEG, NEF raw)

• 🛡️ Data Quality Automation

• Automatic detection of catalog number duplicates across specimens
• Pattern validation for malformed catalog numbers
• Perceptual hash detection for duplicate photography

• Missing required fields flagged for human review

• 📈 Multi-Extraction Aggregation

• Combines results from multiple extraction attempts per specimen
• Selects best candidate per field (highest confidence)
• Enables iterative improvement: reprocess with better models/preprocessing
• All extraction attempts preserved for audit trail

Added - Migration & Analysis Tools

• 🔄 Migration Script (scripts/migrate_to_specimen_index.py)
• Analyzes existing raw.jsonl files from historical runs
• Populates specimen index without modifying original data
• Detects duplicate extractions and reports statistics
• Runs comprehensive data quality checks

• Example usage:

  python scripts/migrate_to_specimen_index.py \
      --run-dir full_dataset_processing/* \
      --index specimen_index.db \
      --analyze-duplicates \
      --check-quality
  

• 📊 Extraction Run Analysis (docs/extraction_run_analysis_20250930.md)

• Documented root cause of duplicate extractions in run_20250930_181456
• ALL 5,770 extractions failed (missing OPENAI_API_KEY)
• Every specimen processed exactly twice (no deduplication)
• Provides recommendations for prevention

Added - Production Infrastructure

Research Impact

Architectural Foundation: - From: Image-centric, duplicates allowed, no specimen tracking - To: Specimen-centric, automatic deduplication, full provenance

Economic Impact: - Eliminates redundant extraction attempts (identified 2,885 duplicates) - Prevents wasted API calls on already-processed specimens - Enables cost-effective iterative improvement via aggregation

Scientific Impact: - Full lineage tracking for reproducibility - Cryptographic traceability (content-addressed images) - Data quality automation (catalog validation, duplicate detection) - Supports progressive publication with human review tracking

Technical Implementation

• Database Schema: 7 tables tracking specimens, transformations, extractions, aggregations, reviews, quality flags
• Deduplication Key: SHA256(extraction_params) for deterministic caching
• Aggregation Strategy: Multi-extraction results combined, best candidate per field selected
• Quality Checks: Automated SQL queries detect violations of expected invariants
• Migration Safety: Additive only, original data never modified, full rollback capability

Backward Compatibility

✅ Fully Backward Compatible - Existing extraction runs remain valid (no modification) - Old workflow continues to work without migration - New features opt-in via migration script - No breaking changes to CLI interface - Gradual adoption supported

Production Readiness

• ✅ Async web architecture (Quart + Hypercorn)
• ✅ Docker containerization with health checks
• ✅ Data quality automation
• ✅ Full provenance tracking
