# Story 3.3: Content Interlinking Injection - COMPLETE ✅
**Status**: Implemented, Integrated, Tested, and Production-Ready
**Date Completed**: October 21, 2025
---
## Summary
Story 3.3 is **100% COMPLETE** including:
- ✅ Core implementation (`src/interlinking/content_injection.py`)
- ✅ Full test coverage (42 tests, 100% passing)
- ✅ CLI integration (`src/generation/batch_processor.py`)
- ✅ Real-world validation (tested with live batch generation)
- ✅ Zero linter errors
- ✅ Documentation updated
---
## What Was Delivered
### 1. Core Functionality
**File**: `src/interlinking/content_injection.py` (410 lines)
Three types of link injection:
- **Tiered Links**: T1→money site, T2+→lower-tier articles
- **Homepage Links**: All articles→`/index.html` with "Home" anchor
- **See Also Section**: Each article→all other batch articles
Features:
- Tier-based anchor text with job config overrides (default/override/append)
- Case-insensitive anchor text matching
- First occurrence only (prevents over-optimization)
- Fallback insertion when anchor not found
- Database link tracking (`article_links` table)
### 2. Template Updates
All 4 HTML templates now have navigation menus:
- `src/templating/templates/basic.html`
- `src/templating/templates/modern.html`
- `src/templating/templates/classic.html`
- `src/templating/templates/minimal.html`
Each template has theme-appropriate styling for:
```html
<nav>
<ul>
<li><a href="/index.html">Home</a></li>
<li><a href="about.html">About</a></li>
<li><a href="privacy.html">Privacy</a></li>
<li><a href="contact.html">Contact</a></li>
</ul>
</nav>
```
### 3. Test Coverage
**Unit Tests**: `tests/unit/test_content_injection.py` (33 tests)
- Homepage URL extraction
- HTML insertion
- Anchor text finding & wrapping
- Link injection fallback
- Anchor text config modes
- All helper functions
**Integration Tests**: `tests/integration/test_content_injection_integration.py` (9 tests)
- Full T1 batch with money site links
- T2 batch linking to T1 articles
- Anchor text config overrides
- Different batch sizes (1-20 articles)
- Database link records
- Internal vs external links
**Result**: 42/42 tests passing (100%)
### 4. CLI Integration
**File**: `src/generation/batch_processor.py`
Added complete post-processing pipeline:
1. **Site Assignment** (Story 3.1) - Automatic assignment from pool
2. **URL Generation** (Story 3.1) - Final public URLs
3. **Tiered Links** (Story 3.2) - Find money site or lower-tier URLs
4. **Content Injection** (Story 3.3) - Inject all links
5. **Template Application** - Apply HTML templates
### 5. Database Integration
Updated `src/database/repositories.py`:
- Added `require_site` parameter to `get_by_project_and_tier()`
- Backward compatible (default maintains existing behavior)
All links tracked in `article_links` table:
- `link_type="tiered"` - Money site or lower-tier links
- `link_type="homepage"` - Homepage links to `/index.html`
- `link_type="wheel_see_also"` - See Also section links

## How It Works Now
### Before Story 3.3
```
uv run python main.py generate-batch --job-file jobs/example.json
Result:
- Articles generated ✓
- Raw HTML, no links ✗
- Not ready for deployment ✗
```
### After Story 3.3
```
uv run python main.py generate-batch --job-file jobs/example.json
Result:
- Articles generated ✓
- Sites auto-assigned ✓
- URLs generated ✓
- Tiered links injected ✓
- Homepage links injected ✓
- See Also sections added ✓
- Templates applied ✓
- Ready for deployment! ✓
```
