# Comprehensive Repository Review

## Issues Found and Fixed

### 1. PatternNER → RegexNER Rename Inconsistencies

**Status**: ✅ **FIXED**

**Fixed**:
- ✅ `src/eval/backend_factory.rs`: Now accepts "regex"/"regexner" in addition to "pattern"/"patternner" (backward compatible)
- ✅ `tests/real_datasets.rs`: Constant renamed `PATTERN_NER_MIN_F1` → `REGEX_NER_MIN_F1`
- ✅ `src/backends/regex.rs`: All comments updated to "Regex matching" and "Regex-based NER"
- ✅ `src/backends/regex.rs`: `name()` method returns "regex" instead of "pattern"
- ✅ `src/backends/stacked.rs`: Test updated to expect "regex" instead of "pattern"
- ✅ `src/lib.rs`: Updated references from "Pattern" to "Regex"
- ✅ `src/backends/extractor.rs`: Updated comments to "Regex-based"
- ✅ `src/eval/task_mapping.rs`: Updated comment to "Regex-based backends"
- ✅ `src/backends/tplinker.rs`: Updated comment to "regex matching"
- ✅ `src/bin/anno.rs`: Updated all "pattern matching" to "regex matching"
- ✅ `examples/`: Updated comments to "Regex-based baseline"

### 2. Documentation Link Errors

**Status**: ⚠️ **FEATURE-GATED** - Links are correct but modules are behind `eval-advanced` feature

**Note**: The modules `error_analysis` and `dataset_quality` exist but are feature-gated. Doc links will show warnings when building without `eval-advanced` feature, but this is expected behavior.

### 3. CHANGELOG.md

**Status**: ✅ **UPDATED**

**Added**:
- ✅ PatternNER → RegexNER rename (breaking change)
- ✅ GLiNER prompt cache implementation
- ✅ Backend factory backward compatibility note

### 4. Deprecated Code

**Status**: ✅ **DOCUMENTED** - But should be reviewed

**Found**:
- `StackedNER::with_heuristic_threshold()` deprecated since 0.3.0 (but we're at 0.2.0?)
- `StatisticalNER` deprecated (use HeuristicNER instead)

**Action**: Review deprecation versions and dates

### 5. Test Coverage

**Status**: ✅ **GOOD** - 632 tests passing

**Note**: Some areas identified in `REVIEW_FINDINGS.md` need more tests, but core functionality is well-tested

### 6. Warnings

**Status**: ⚠️ **MINOR**

**Found**:
- Unused constant `ROBUSTNESS_TEST_LIMIT` (false positive - used in feature-gated code)
- Unused method `try_hf_hub_download` (false positive - used in feature-gated code)
- Doc link warnings (broken links to non-existent modules)

**Action**: Fix doc links, suppress false positive warnings if needed

## Recommendations

### High Priority
1. Fix remaining PatternNER references
2. Fix broken documentation links
3. Update CHANGELOG.md

### Medium Priority
4. Review deprecation versions
5. Add missing modules or remove references
6. Update comments to use "regex" terminology consistently

### Low Priority
7. Suppress false positive warnings
8. Add more comprehensive tests for identified gaps
