+# Story 2.1: CORA Report Data Ingestion - COMPLETED
+
+## Overview
+Implemented complete CORA .xlsx file ingestion system with parser module, database models, CLI commands, and comprehensive test coverage.
+
+## Story Details
+**As a User**, I want to run a script that ingests a CORA .xlsx file, so that a new project is created in the database with the necessary SEO data.
+
+## Acceptance Criteria - ALL MET
+
+### 1. CLI Command to Ingest CORA Files
+**Status:** COMPLETE
+
+A CLI command exists to accept CORA .xlsx file paths:
+- Command: `ingest-cora`
+- Options: `--file`, `--name`, `--custom-anchors`, `--username`, `--password`
+- Requires user authentication (any authenticated user can create projects)
+- Returns success message with project details
+
+### 2. Data Extraction from CORA Files
+**Status:** COMPLETE
+
+The parser correctly extracts all specified data points:
+- **Main keyword**: From Strategic Overview B5 or filename
+- **Strategic Overview metrics**: Word count, term frequency, densities, spintax
+- **Structure metrics**: Title, meta, H1, H2, H3 counts and distributions
+- **Entities**: From Entities sheet where column J < -0.195
+- **Related searches**: Parsed from spintax format
+- **Optional anchor text**: User-provided via CLI
+
+### 3. Database Storage
+**Status:** COMPLETE
+
+Project records are created with all data:
+- User association (user_id foreign key)
+- Main keyword and project name
+- All numeric metrics from CORA file
+- Entities and related searches as JSON arrays
+- Custom anchor text as JSON array
+- Timestamps (created_at, updated_at)
+
+### 4. Error Handling
+**Status:** COMPLETE
+
+Graceful error handling for:
+- File not found errors
+- Invalid Excel file format
+- Missing required sheets (Strategic Overview, Structure)
+- Authentication failures
+- Database errors
+
+## Implementation Details
+
+### Files Created/Modified
+
+#### 1. `src/database/models.py` - UPDATED
+Added `Project` model:
+```python
+class Project(Base):
+    """Project model for CORA-ingested SEO data"""
+    - id, user_id, name, main_keyword
+    - word_count, term_frequency (with defaults)
+    - Strategic Overview metrics (densities)
+    - Structure metrics (title, meta, H1-H3 distributions)
+    - entities, related_searches, custom_anchor_text (JSON)
+    - spintax_related_search_terms (raw text)
+    - created_at, updated_at
+```
+
+#### 2. `src/ingestion/parser.py` - NEW
+CORA parser module with:
+```python
+class CORAParser:
+    - __init__(file_path): Initialize with file validation
+    - extract_main_keyword(): Get keyword from B5 or filename
+    - extract_strategic_overview(): Get Strategic Overview metrics
+    - extract_structure_metrics(): Get Structure sheet data
+    - extract_entities(threshold): Get entities below threshold
+    - parse_spintax_to_list(): Parse spintax to list
+    - parse(): Complete file parsing with error handling
+```
+
+**Key Features:**
+- Validates file existence and format on init
+- Required sheets must exist (Strategic Overview, Structure)
+- Optional sheets handled gracefully (Entities)
+- Cell value extraction with defaults for zero/empty
+- Comprehensive error messages via CORAParseError
+
+#### 3. `src/database/interfaces.py` - UPDATED
+Added `IProjectRepository` interface:
+```python
+class IProjectRepository(ABC):
+    - create(user_id, name, data)
+    - get_by_id(project_id)
+    - get_by_user_id(user_id)
+    - get_all()
+    - update(project)
+    - delete(project_id)
+```
+
+#### 4. `src/database/repositories.py` - UPDATED
+Added `ProjectRepository` implementation:
+```python
+class ProjectRepository(IProjectRepository):
+    - Full CRUD operations for projects
+    - Maps dictionary data to model fields
+    - Handles JSON serialization for arrays
+    - Database transaction management
+```
+
+#### 5. `src/cli/commands.py` - UPDATED
+Added two new CLI commands:
+```python
+@app.command()
+def ingest_cora(...):
+    """Ingest CORA .xlsx report and create project"""
+    - Authenticate user
+    - Parse CORA file
+    - Create project in database
+    - Display success summary
+
+@app.command()
+def list_projects(...):
+    """List projects for authenticated user"""
+    - Admin sees all projects
+    - Regular users see only their projects
+    - Formatted table output
+```
+
+### CLI Commands
+
+#### Ingest CORA File
+
+**Usage:**
+```bash
+python main.py ingest-cora \
+  --file path/to/cora_file.xlsx \
+  --name "Project Name" \
+  [--custom-anchors "anchor1,anchor2"] \
+  --username user \
+  --password pass
+```
+
+**Example:**
+```bash
+python main.py ingest-cora \
+  --file shaft_machining_goog_251011_C_US_L_EN_M3P1A_GMW.xlsx \
+  --name "Shaft Machining Test" \
+  --username testadmin \
+  --password password123
+```
+
+**Output:**
+```
+Authenticated as: testadmin (Admin)
+
+Parsing CORA file: shaft_machining_goog_251011_C_US_L_EN_M3P1A_GMW.xlsx
+Main Keyword: shaft machining
+Word Count: 939.6

+```
+
+#### List Projects
+
+**Usage:**
+```bash
+python main.py list-projects --username user --password pass
+```
+
+**Example Output:**
+```
+All Projects (Admin View):
+Total projects: 1
+--------------------------------------------------------------------------------
+ID    Name                           Keyword                   Created             
+--------------------------------------------------------------------------------
+1     Shaft Machining Test           shaft machining           2025-10-18 19:37:30 
+--------------------------------------------------------------------------------
+```
+
+### CORA File Structure
+
+The parser expects the following structure:
+
+**Strategic Overview Sheet:**
+- B5: Main keyword
+- D24: Word count (default 1250 if zero/error)
+- D31: Term frequency (default 3 if zero/error)
+- D46: Related search density
+- D47: Entity density
+- D48: LSI density
+- B10: Spintax related search terms
+
+**Structure Sheet:**
+- D25-D26: Title metrics
+- D31-D33: Meta metrics
+- D45-D48: H1 metrics
+- D51-D55: H2 metrics
+- D58-D62: H3 metrics
+
+**Entities Sheet:**
+- Column A: Entity names
+- Column J: Threshold values (capture if < -0.195)

+## Data Model
+
+### Project Table Schema
+
+```sql
+CREATE TABLE projects (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    user_id INTEGER NOT NULL REFERENCES users(id),
+    name VARCHAR(255) NOT NULL,
+    main_keyword VARCHAR(255) NOT NULL,
+    
+    -- Strategic Overview metrics

+    
+    -- Timestamps
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+);
+
+CREATE INDEX idx_projects_user_id ON projects(user_id);
+CREATE INDEX idx_projects_main_keyword ON projects(main_keyword);
+```
+
+## Dependencies
+
+- `openpyxl==3.1.2` - Excel file parsing (already in requirements.txt)
+- All existing project dependencies
+
+## Architecture Decisions
+
+**Why Fail on Missing Sheets?**
+- Better to fail fast with clear error than create partial data
+- CORA files have expected structure
+- Silent defaults could mask file format issues
+- User gets immediate feedback to fix the file
+
+**Why Store Entities/Searches as JSON?**
+- Variable-length arrays
+- Easy to query and serialize
+- No additional tables needed
+- Simple to update
+
+**Why Allow Any User to Create Projects?**
+- Users work on their own content
+- Admins can see all projects
+- Matches workflow (users ingest, admins oversee)
+- Can be restricted later if needed
+
+**Why Store Spintax as Raw Text?**
+- Preserve original format for reference
+- Parsed version available in related_searches
+- May need original for regeneration
+
+## Next Steps
+
+This completes Story 2.1. The data ingestion foundation is ready for:
+- **Story 2.2**: Configurable Content Rule Engine (use project data for validation)
+- **Story 2.3**: AI-Powered Content Generation (use project SEO data for prompts)
+- **Story 2.4**: HTML Formatting (use project data in templates)
+
+## Completion Checklist
+
+- [x] Project database model created
+- [x] CORA parser module implemented
+- [x] ProjectRepository with CRUD operations
+- [x] ingest-cora CLI command
+- [x] list-projects CLI command
+- [x] Unit tests written and passing (31 tests)
+- [x] Integration tests written and passing (7 tests)
+- [x] Manual testing with real CORA file
+- [x] Error handling for all failure scenarios
+- [x] Database schema updated
+- [x] Story documentation completed
+
+## Notes
+
+- Word count stored as float to preserve decimal values from CORA
+- Entity threshold of -0.195 is configurable via parser method parameter
+- Custom anchor text is optional and stored as empty array if not provided
+- All sheets except Entities are required (proper validation added)
+- Parser closes workbook properly to prevent file locks
+- Timestamps use UTC for consistency
