+# Story 2.2: Configurable Content Rule Engine
+
+## Overview
+Implementation of a CORA-compliant content validation engine that ensures AI-generated HTML meets both universal quality standards and project-specific CORA targets.
+
+## Status
+**COMPLETED**
+
+## Implementation Details
+
+### 1. Database Changes
+- Added `tier` field to `Project` model (default=1, indexed)
+- Created migration script: `scripts/add_tier_to_projects.py`
+- Tier 1 = strictest validation (default)
+- Tier 2+ = warnings only for CORA target misses
+
+### 2. Configuration Updates
+**File:** `master.config.json`
+
+Restructured `content_rules` with two validation levels:
+
+**Universal Rules** (apply to all tiers, hard failures):
+- `min_content_length`: 1000 words minimum
+- `max_content_length`: 5000 words maximum
+- `title_exact_match_required`: Title must contain main keyword
+- `h1_exact_match_required`: H1 must contain main keyword
+- `h2_exact_match_min`: At least 1 H2 with main keyword
+- `h3_exact_match_min`: At least 1 H3 with main keyword
+- `faq_section_required`: Must include FAQ section
+- `faq_question_restatement_required`: FAQ answers restate questions
+- `image_alt_text_keyword_required`: Alt text must contain keyword
+- `image_alt_text_entity_required`: Alt text must contain entities
+
+**CORA Validation Config**:
+- `enabled`: Toggle CORA validation on/off
+- `tier_1_strict`: Tier 1 fails on CORA target misses
+- `tier_2_plus_warn_only`: Tier 2+ only warns
+- `round_averages_down`: Round CORA averages down (e.g., 5.6 → 5)
+
+### 3. Core Rule Engine
+**File:** `src/generation/rule_engine.py`
+
+**Classes:**
+- `ValidationIssue`: Single validation error or warning
+- `ValidationResult`: Complete validation result with errors/warnings
+- `ContentHTMLParser`: Extracts structure from HTML (H1/H2/H3/images/links/text)
+- `ContentRuleEngine`: Main validation engine
+
+**Key Features:**
+- HTML parsing and element extraction
+- Keyword/entity counting with word boundary matching
+- Universal rule validation (hard failures)
+- CORA target validation (tier-aware)
+- FAQ section detection
+- Image alt text validation
+- Detailed error/warning reporting
+
+### 4. Config System Updates
+**File:** `src/core/config.py`
+
+Added:
+- `UniversalRulesConfig` model
+- `CORAValidationConfig` model
+- Updated `ContentRulesConfig` to use nested structure
+- Added `Config.get()` method for dot notation access (e.g., `config.get("content_rules.universal")`)
+
+### 5. Tests
+**File:** `tests/unit/test_rule_engine.py`
+
+**21 comprehensive tests covering:**
+- HTML parser functionality (6 tests)
+- ValidationResult class (4 tests)
+- Universal rules validation (6 tests)
+- CORA target validation (4 tests)
+- Fully compliant content (1 test)
+
+**All tests passing ✓**
+
+## Usage Example
+
+```python
+from src.generation.rule_engine import ContentRuleEngine
+from src.core.config import get_config
+from src.database.models import Project
+
+# Initialize engine
+config = get_config()
+engine = ContentRuleEngine(config)
+
+# Validate content
+html_content = "..."
+project = # ... load from database
+result = engine.validate(html_content, project)
+
+if result.passed:
+ print("Content is valid!")
+else:
+ print(f"Errors: {len(result.errors)}")
+ for error in result.errors:
+ print(f" - {error.message}")
+
+ print(f"Warnings: {len(result.warnings)}")
+ for warning in result.warnings:
+ print(f" - {warning.message}")
+
+# Get detailed report
+report = result.to_dict()
+```
+
+## Validation Logic
+
+### Universal Rules (All Tiers)
+1. **Word Count**: Content length between min/max bounds
+2. **Title**: Must contain main keyword
+3. **H1**: At least one H1 with main keyword
+4. **H2/H3 Minimums**: Minimum keyword counts
+5. **FAQ**: Must have FAQ section
+6. **Images**: Alt text contains keyword + entities
+
+### CORA Targets (Tier-Aware)
+For each CORA metric (h1_exact, h2_total, h2_entities, etc.):
+- **Tier 1**: FAIL if actual < target (rounded down)
+- **Tier 2+**: WARN if actual < target (but pass)
+
+### Keyword Matching
+- Case-insensitive
+- Word boundary detection (avoids partial matches)
+- Supports related searches and entities
+
+## Acceptance Criteria
+
+✅ System loads "content_rules" from master JSON configuration
+✅ Validates H1 tag contains main keyword
+✅ Validates at least one H2 starts with main keyword
+✅ Validates other H2s incorporate entities and related searches
+✅ Validates H3 tags similarly to H2s
+✅ Validates FAQ section format
+✅ Validates image alt text contains keyword and entities
+✅ Tier-based validation (strict for Tier 1, warnings for Tier 2+)
+✅ Rounds CORA averages down as configured
+✅ All tests passing (21/21)
+
+## Files Modified
+
+1. `src/database/models.py` - Added tier field to Project
+2. `master.config.json` - Restructured content_rules
+3. `src/core/config.py` - Added config models and get() method
+4. `src/generation/rule_engine.py` - Implemented validation engine
+5. `scripts/add_tier_to_projects.py` - Database migration
+6. `tests/unit/test_rule_engine.py` - Comprehensive test suite
+
+## Next Steps (Story 2.3)
+
+The rule engine is ready to be integrated into Story 2.3 (AI-Powered Content Generation):
+- Story 2.3 will use this engine to validate AI-generated content
+- Can implement retry logic if validation fails
+- Engine provides detailed feedback for AI prompt refinement
