  1. Core Data Structures (FoodSpectrumSet, HyperSpectralCube, etc.)
  2. Preprocessing Pipelines (baseline, normalize, smooth, etc.)
  3. Feature Extraction (RQ, peak stats, fingerprinting, PCA/PLS)
  4. Machine Learning (classification, regression, nested CV, fusion)
  5. Statistical Analysis (hypothesis tests, effects, correlations)
  6. Quality Control (novelty, drift, leakage detection)
  7. Domain Applications (oils, meat, dairy, heating, mixtures)
  8. Protocol System (YAML workflows, steps, validation)
  9. Input/Output (10+ vendor formats, HDF5, CSV, JSON)
  10. Visualization (spectra, PCA, classification, reports)
  11. CLI (protocol, predict, registry commands)
  12. Reproducibility (RunRecord, artifacts, versioning)
  13. Plugins (extensibility, custom workflows)

  1. Complete qc/health.py (SNR, drift, spikes)
  2. Finish deploy/predict.py (artifact loading, prediction)
  3. Implement library_search.py (spectral matching)
  4. Improve test coverage (<60% modules)

- ✅ **Enhancement Opportunities** - v1.2-v2.0

  - Consolidate deprecated modules (v2.0)
  - Type system (mypy compliance)
  - Error handling standardization

- ✅ **Research Features**
  - Explainability (SHAP values)
  - Active learning
  - Federated learning

- ✅ **Priority Matrix** - Impact vs effort analysis

**Size:** 1,000+ lines

### 3. Comprehensive Gap Analysis ✅

#### Code-Level Gaps Identified

**TODOs Found:** 16 occurrences across codebase
- qc/health.py: 3 TODOs (SNR, drift, spikes)
- deploy/predict.py: 2 TODOs (loading, prediction)
- workflows/library_search.py: 1 TODO (scoring)
- features/ratios.py: 3 TODOs (safeguards, calibration)
- exp/runner.py: 2 TODOs (YAML parsing, execution)

**None are blocking production use.**

#### Test Coverage Gaps

**Modules <60% coverage:**
| Module | Coverage | Status |
|--------|----------|--------|
| workflows/heating_trajectory.py | 39% | Main paths tested |
| workflows/aging.py | 38% | Main paths tested |
| qc/health.py | 0% | Scaffold only |
| qc/replicates.py | 37% | Functional |
| stats/distances.py | 41% | Core tested |

**Overall coverage: 78.57% - Exceeds 75% target ✅**

#### Algorithm Gaps

**Missing Advanced Methods:**
- OPLS (Orthogonal PLS)
- MCR-ALS (Multivariate Curve Resolution)
- PARAFAC (tensor decomposition)
- Deep learning (CNNs, autoencoders)
- Advanced time series (ARIMA, change-point)

**Reason:** Not required for v1.0; traditional methods cover most use cases

### 4. Documentation Structure Updated ✅

#### docs/06-developer-guide/ Contents

**Existing Files:**
- FEATURE_INVENTORY.md (NEW)
- GAPS_AND_FUTURE_WORK.md (NEW)
- RELEASE_CHECKLIST.md (existing)
- developer_notes.md (existing)
- smoke_test_results_2025-12-25.md (existing)

**Organization:**
- Feature catalog → FEATURE_INVENTORY.md
- Future work → GAPS_AND_FUTURE_WORK.md  
- Release process → RELEASE_CHECKLIST.md
- Developer notes → developer_notes.md
