# Complete Code-to-Documentation Mapping Reference

## Summary

This document provides a unified reference for mapping **all code entities** (functions, types, interfaces, components, hooks, etc.) to their corresponding documentation.

**Generated**: December 25, 2025

TODO: Audit component/hook documentation coverage, replace TBD values, and update `/src/` path references to match the current `frontends/nextjs/src` layout.

## Code-to-Docs Mapping Process

### Step 1: Locate the Code

```
Question: Where is function X?
    ↓
Answer: /src/lib/{module}.ts
    ↓
Find all exports from that file
```

### Step 2: Find Documentation

```
Question: What documents function X?
    ↓
Path Option 1: /docs/src/lib/README.md → Module overview
Path Option 2: /docs/src/lib/{module}.md → Detailed docs
Path Option 3: /docs/src/lib/FUNCTION_MAPPING.md → Function mapping
```

### Step 3: Reference Documentation

```
Question: Is there a type definition used?
    ↓
Answer: /docs/src/lib/TYPE_DEFINITIONS.md
    ↓
Find the type in one of 60 documented types
```

## Verification Tools

### 1. Directory Coverage Checker
```bash
/tmp/check_doc_coverage.sh [summary|detail|verbose]
```
Verifies directory-to-docs mapping (22/22 = 100%)

### 2. Function Coverage Checker
```bash
/tmp/function_coverage_checker.sh [summary|detail|verbose]
```
Verifies function-to-docs mapping (162 exports cataloged)

### 3. Type Coverage Checker
```bash
/tmp/type_coverage_checker.sh [summary|detail|verbose]
```
Verifies type definition coverage (60/60 = 100%)

### 4. Extract Type Definitions
```bash
/tmp/extract_type_definitions.sh
```
Generates comprehensive type mapping documentation

---

## How to Use These Mappings

### For Code Review
1. Check if new function has corresponding docs
2. Check if new type is in TYPE_DEFINITIONS.md
3. Verify coverage using verification tools

### For Documentation
1. Reference FUNCTION_MAPPING.md for function locations
2. Reference TYPE_DEFINITIONS.md for type definitions
3. Use module documentation files for detailed info

### For Maintenance
1. Update mapping files when adding new exports
2. Run verification tools in CI/CD
3. Keep FUNCTION_MAPPING.md and TYPE_DEFINITIONS.md in sync

### For Navigation
1. Looking for a function? → FUNCTION_MAPPING.md
2. Looking for a type? → TYPE_DEFINITIONS.md
3. Looking for module overview? → README.md
4. Looking for detailed docs? → {module}.md files

---

## Integration with FUNCTION_MAPPING.md

The FUNCTION_MAPPING.md file serves as the primary index and is now updated to include:

1. **Function/Export Mapping** (99% - 161/162)
   - 32 library files
   - 162 total exports
   - 1 gap: seed-data.ts

2. **Type Definition Cross-Reference** (100% - 60/60)
   - Links to TYPE_DEFINITIONS.md
   - Breakdown by category
   - Coverage statistics

---

## Next Steps

### Immediate Priorities
- [ ] Enhance seed-data.ts documentation (1 remaining gap)
- [ ] Create component-level function mapping
- [ ] Document custom hooks comprehensively
- [ ] Integrate tools into CI/CD pipeline

### Future Enhancements
- [ ] Add component interface documentation
- [ ] Document hook return types
- [ ] Create API reference from mappings
- [ ] Generate automatic API docs from mappings
