+# Investigation - External Dogs UI Issues
+
+## Bug Summary
+The "External Dogs" interface does not match the layout and style of the main "Dogs" page. It uses an inconsistent grid layout, lacks the standardized card style, uses different badge implementations, and is missing features like the delete button. Additionally, it uses CSS classes that are not defined in the codebase, leading to broken or default styling.
+
+## Root Cause Analysis
+- **Inconsistent Layout**: `DogList.jsx` (Dogs page) uses a vertical list of horizontal cards, while `ExternalDogs.jsx` uses a grid of square-ish cards.
+- **Undefined CSS Classes**: `ExternalDogs.jsx` references classes like `page-container`, `page-header`, `filter-bar`, and `dog-card` which are not present in `index.css` or `App.css`.
+- **Missing Components**: `ExternalDogs.jsx` uses emoji icons for champion status instead of the `ChampionBadge` and `ChampionBloodlineBadge` components used elsewhere.
+- **Feature Disparity**: The Dogs page includes a delete button with a confirmation modal, which is absent from the External Dogs page.
+- **Helper Usage**: `ExternalDogs.jsx` does not use the `calculateAge` helper, resulting in inconsistent date formatting.
+
+## Affected Components
+- `client/src/pages/ExternalDogs.jsx`
+
+## Implementation Notes
+Refactored `ExternalDogs.jsx` to match `DogList.jsx` in layout, style, and functionality. Key changes:
+- Switched to `axios` for API calls.
+- Adopted the vertical list layout instead of the grid.
+- Used standardized `ChampionBadge` and `ChampionBloodlineBadge` components.
+- Added a search/filter bar consistent with the main Dogs page.
+- Implemented delete functionality with a confirmation modal.
+- Standardized age calculation using the `calculateAge` helper logic.
+- Added an "EXT" badge to the dog avatars to clearly identify them as external dogs while maintaining the overall style.
+
+## Test Results
+- Verified that all components are correctly imported.
+- Verified that API endpoints match the backend routes.
+- Code review shows consistent use of CSS variables and classes (e.g., `container`, `card`, `btn`).

+# Investigation: Bug in Pairing Simulator
+
+## Bug Summary
+In the Pairing Simulator page, clicking the "Simulate Pairing" button results in the following error:
+`Unexpected token '<', "<!--DOCTYPE "... is not valid JSON`
+
+## Root Cause Analysis
+The frontend `PairingSimulator.jsx` makes a POST request to `/api/pedigree/coi` when simulating a pairing. However, the backend `server/routes/pedigree.js` does not define a `/coi` route. Instead, it defines a `/trial-pairing` route that performs the same function.
+
+When the frontend calls the non-existent `/api/pedigree/coi` route, the server returns an HTML 404 page (or the SPA's `index.html` if in production). The frontend then tries to parse this HTML as JSON, leading to the reported error.
+
+Additionally, `PedigreeView.jsx` attempts to call `GET /api/pedigree/:id/coi`, which is also not implemented in the backend.
+
+## Affected Components
+- `client/src/pages/PairingSimulator.jsx`: Calls `/api/pedigree/coi` (POST).
+- `client/src/pages/PedigreeView.jsx`: Calls `/api/pedigree/:id/coi` (GET).
+- `server/routes/pedigree.js`: Missing route definitions for `/coi` and `/:id/coi`.
+
+## Proposed Solution
+1. Update `server/routes/pedigree.js` to:
+   - Alias `POST /api/pedigree/coi` to the existing `trial-pairing` logic.
+   - Implement `GET /api/pedigree/:id/coi` to return the COI for an existing dog based on its parents.
+2. Ensure the COI value returned by the API is consistent with what the frontend expects (0-1 range). Currently, the backend returns a 0-100 range, while the `PairingSimulator.jsx` expects 0-1 and multiplies by 100 in the UI.
+
+## Implementation Plan
+1.  **Backend Changes**:
+    -   Modify `server/routes/pedigree.js` to add `router.post('/coi', ...)` using the same logic as `trial-pairing`.
+    -   Add `router.get('/:id/coi', ...)` to `server/routes/pedigree.js`.
+    -   Adjust the `calculateCOI` response or the route handlers to return COI in the 0-1 range (e.g. `0.05` for 5%) to match `PairingSimulator.jsx`'s expectation.
+2.  **Frontend Cleanup**:
+    -   Check if `PedigreeView.jsx` and `pedigreeHelpers.js` need adjustments once the backend returns the 0-1 range. `formatCOI` in `pedigreeHelpers.js` currently expects 0-100 (it checks `coi <= 5`), so there's an inconsistency in the frontend itself.

+## Agent Instructions
+
+If you are blocked and need user clarification, mark the current step with `[!]` in plan.md before stopping.

+## Workflow Steps
+
+### [x] Step: Requirements
+<!-- chat-id: c41b4352-a09d-4280-9aa2-cf29378edb68 -->
+
+Create a Product Requirements Document (PRD) based on the feature description.
+
+1. Review existing codebase to understand current architecture and patterns
+2. Analyze the feature definition and identify unclear aspects
+3. Ask the user for clarifications on aspects that significantly impact scope or user experience
+4. Make reasonable decisions for minor details based on context and conventions
+5. If user can't clarify, make a decision, state the assumption, and continue
+
+Save the PRD to `{@artifacts_path}/requirements.md`.
+
+### [x] Step: Technical Specification
+<!-- chat-id: c8a2d821-c232-4b10-a4b9-471df9e53543 -->
+
+Create a technical specification based on the PRD in `{@artifacts_path}/requirements.md`.
+
+1. Review existing codebase architecture and identify reusable components
+2. Define the implementation approach
+
+Save to `{@artifacts_path}/spec.md` with:
+- Technical context (language, dependencies)
+- Implementation approach referencing existing code patterns
+- Source code structure changes
+- Data model / API / interface changes
+- Delivery phases (incremental, testable milestones)
+- Verification approach using project lint/test commands
+
+### [x] Step: Planning
+<!-- chat-id: 5128cbb3-0529-47f2-a7ac-9a978ea72267 -->
+
+Create a detailed implementation plan based on `{@artifacts_path}/spec.md`.
+
+1. Break down the work into concrete tasks
+2. Each task should reference relevant contracts and include verification steps
+3. Replace the Implementation step below with the planned tasks
+
+Rule of thumb for step size: each step should represent a coherent unit of work (e.g., implement a component, add an API endpoint). Avoid steps that are too granular (single function) or too broad (entire feature).
+
+Important: unit tests must be part of each implementation task, not separate tasks. Each task should implement the code and its tests together, if relevant.
+
+If the feature is trivial and doesn't warrant full specification, update this workflow to remove unnecessary steps and explain the reasoning to the user.
+
+Save to `{@artifacts_path}/plan.md`.
+
+### [x] Phase 1: Create DEVELOPMENT.md
+<!-- chat-id: 0da2c64e-4b20-423d-9049-46fc0467eaec -->
+1. Research tech stack, monorepo structure, and database schemas in `server/db/`.
+2. Document the "Parents Table" approach and database initialization/migration.
+3. Add setup and development commands.
+4. Verify correctness against `server/db/init.js` and `package.json`.
+
+### [x] Phase 2: Create API.md
+<!-- chat-id: bde368a7-164c-419e-b4b9-582e6ced4a45 -->
+1. Research all routes in `server/routes/` for endpoints, methods, parameters, and responses.
+2. Document endpoint groups: Dogs, Litters, Health, Genetics, Breeding, and Settings.
+3. Provide JSON schema examples for key data models (Dog, Litter, etc.).
+4. Verify endpoints against route handlers in `server/routes/`.
+
+### [x] Phase 3: Create FRONTEND_GUIDE.md
+<!-- chat-id: f0c53f46-3014-4030-9433-3df4d730fde7 -->
+1. Research React patterns, hooks (`useSettings`), and `PedigreeTree` logic.
+2. Document routing, state management, and key reusable components (`DogForm`, `PedigreeTree`, etc.).
+3. Explain styling conventions and theme implementation using CSS variables.
+4. Verify patterns against `client/src/App.jsx`, `client/src/hooks/`, and `client/src/components/`.
+
+### [x] Phase 4: Final Review and Verification
+<!-- chat-id: b87b4e6a-5d6a-4ad2-91dc-70916b830845 -->
+1. Cross-reference all new documentation files with the current codebase (v0.6.1).

+# Product Requirements Document (PRD) - INIT (Codebase Documentation)
+
+## 1. Goal
+The primary goal of this task is to perform a comprehensive scan of the Breedr codebase and create essential developer-focused documentation (`.md` files). This documentation will streamline the onboarding of new agents or developers and simplify the process of implementing new features and fixing bugs.
+
+## 2. Target Audience
+- AI Agents performing code modifications.
+- Human developers contributing to the project.
+
+## 3. Scope of Documentation
+
+### 3.1 DEVELOPMENT.md (Architecture & General Guide)
+This document will serve as the entry point for understanding the Breedr system.
+- **Tech Stack Overview**: React, Express, SQLite (better-sqlite3).
+- **Architecture**: Monorepo structure (`client/`, `server/`), data flow, and core principles.
+- **Database System**: Detailed explanation of the "Parents Table" approach vs. traditional `sire_id`/`dam_id` columns, migration strategies, and schema initialization.
+- **Project Structure**: High-level explanation of key directories and files.
+- **Development Workflow**: How to run the app locally, common commands, and testing procedures (if any).
+- **Coding Standards**: Patterns for backend routes and frontend components.
+
+### 3.2 API.md (REST API Documentation)
+A comprehensive list of all backend API endpoints.
+- **Endpoint Definitions**: URL, method, and purpose.
+- **Request Parameters**: Headers, query params, and body schemas.
+- **Response Format**: Expected JSON structure and status codes.
+- **Key Models**: Descriptions of key data objects (Dog, Litter, Heat Cycle, Pedigree, Settings).
+
+### 3.3 FRONTEND_GUIDE.md (UI/UX & React Patterns)
+A guide focusing on the client-side implementation.
+- **Context & Hooks**: Documentation of `useSettings`, `SettingsProvider`, and any other shared state mechanisms.
+- **Component Patterns**: Key reusable components (`DogForm`, `PedigreeTree`, etc.).
+- **Styling**: Use of CSS custom properties (theming) and global styles.
+- **Pedigree Visualization**: How `react-d3-tree` is integrated and used for genealogy mapping.
+- **Routing**: Client-side navigation structure using `react-router-dom`.
+
+## 4. Non-Functional Requirements
+- **Consistency**: Documentation must match the current state (v0.6.1) of the codebase.
+- **Clarity**: Use clear, concise language and code examples where appropriate.
+- **Maintainability**: Organize documents so they are easy to update when new features are added.
+
+## 5. Success Criteria
+- The three proposed documentation files (`DEVELOPMENT.md`, `API.md`, `FRONTEND_GUIDE.md`) are created in the project root.
+- The documentation accurately reflects the current codebase architecture, API, and frontend patterns.
+- An agent can use these documents to understand how to implement a new feature (e.g., adding a new field to the Dog model) without scanning the entire codebase.

+# Technical Specification - Codebase Documentation (INIT)
+
+This specification outlines the plan for creating comprehensive developer documentation for the Breedr codebase.
+
+## Technical Context
+- **Backend**: Node.js, Express, `better-sqlite3`.
+- **Frontend**: React (Vite), `react-router-dom`, `axios`, `react-d3-tree`.
+- **Database**: SQLite (managed via `server/db/init.js` and `server/db/migrations.js`).
+- **Structure**: Monorepo-style with `client/` and `server/` directories.
+
+## Implementation Approach
+
+The documentation will be split into three main Markdown files in the project root:
+
+1. **DEVELOPMENT.md**: Focuses on architecture, database design, and workflow.
+2. **API.md**: Detailed documentation of all REST API endpoints.
+3. **FRONTEND_GUIDE.md**: Focuses on React patterns, components, and styling.
+
+### Research Methodology
+- **Database**: Analyze `server/db/init.js` for table schemas and `parents` table logic.
+- **API**: Scan `server/routes/*.js` for endpoints, middleware, and request/response structures.
+- **Frontend**: Analyze `client/src/App.jsx` for routing, `client/src/hooks/` for state management, and `client/src/components/` for reusable patterns.
+
+## Source Code Structure Changes
+No changes to existing source code are required. Three new files will be created in the root directory:
+- `/DEVELOPMENT.md`
+- `/API.md`
+- `/FRONTEND_GUIDE.md`
+
+## Documentation Structure
+
+### 1. DEVELOPMENT.md
+- **Overview**: System purpose and high-level architecture.
+- **Project Layout**: Description of key directories (`client`, `server`, `data`, `static`, `uploads`).
+- **Database Design**:
+    - Explain the "Parents Table" approach (decoupling genealogy from the `dogs` table).
+    - Schema overview (Dogs, Litters, Health, Genetics, Settings).
+    - Initialization and migration process.
+- **Getting Started**:
+    - `npm install` (root and client).
+    - `npm run dev` (concurrent execution).
+    - Database initialization (`npm run db:init`).
+- **Coding Standards**: Backend route structure, async/await usage, error handling.
+
+### 2. API.md
+- **Base URL**: `/api`
+- **Authentication**: (Note if any exists, currently seems open).
+- **Endpoint Groups**:
+    - `Dogs`: CRUD operations, photo management, parent/offspring retrieval.
+    - `Litters`: Management of whelping records.
+    - `Health`: OFA records and test results.
+    - `Genetics`: DNA panel markers and results.
+    - `Breeding`: Breeding records and pairing simulations.
+    - `Settings`: Kennel profile management.
+- **Data Models**: JSON schema examples for Dog, Litter, HealthRecord, etc.
+
+### 3. FRONTEND_GUIDE.md
+- **Tech Stack**: Vite, React, CSS Modules/Global CSS.
+- **Routing**: `react-router-dom` configuration in `App.jsx`.
+- **State Management**: `SettingsProvider` and `useSettings` hook.
+- **Pedigree Engine**: Implementation of `react-d3-tree` and `pedigreeHelpers.js`.
+- **Key Components**:
+    - `DogForm`: Complex form with parent selection.
+    - `PedigreeTree`: SVG-based genealogy visualization.
+    - `ClearanceSummaryCard`: Health status overview.
+- **Styling**: Theming with CSS variables (found in `index.css` and `App.css`).
+
+## Delivery Phases
+
+### Phase 1: Core Architecture & Database (DEVELOPMENT.md)
+- Document the tech stack and monorepo structure.
+- Detail the SQLite schema and genealogy logic.
+- Add setup and development commands.
+
+### Phase 2: API Documentation (API.md)
+- Document all routes in `server/routes/`.
+- Provide request/response examples.
+- Document the `parents` table integration in API responses.
+
+### Phase 3: Frontend Guide (FRONTEND_GUIDE.md)
+- Document React component patterns and hooks.
+- Explain the pedigree visualization logic.
+- Document routing and styling conventions.
+
+## Verification Approach
+- **Correctness**: Cross-reference documented schemas with `server/db/init.js`.
+- **Accuracy**: Test documented API endpoints against the running server if possible, or verify via route handlers.
+- **Completeness**: Ensure all components in `client/src/components` and routes in `server/routes` are mentioned or categorized.
+- **Formatting**: Use `markdownlint` (if available) or manual review to ensure readability.

+# Bug Investigation & Implementation Report - Task 7382
+
+## Bug Summary
+The Pairing Simulator was failing with the error: `Unexpected token '<', "<!DOCTYPE "... is not valid JSON`. This was caused by the frontend calling API endpoints (`POST /api/pedigree/coi` and `GET /api/pedigree/:id/coi`) that were not implemented in the backend, leading to HTML 404/SPA responses instead of JSON.
+
+## Root Cause Analysis
+1. **Endpoint Mismatch**: The frontend called `POST /api/pedigree/coi` (Pairing Simulator) and `GET /api/pedigree/:id/coi` (Pedigree View), but the server only implemented `POST /api/pedigree/trial-pairing`.
+2. **COI Scaling Inconsistency**: The server returned COI as a percentage (0-100) in some cases and as a decimal (0-1) in others, while various frontend components (`PairingSimulator.jsx`, `PedigreeView.jsx`, `PedigreeTree.jsx`, `pedigreeHelpers.js`) had differing expectations.
+3. **Data Mapping**: In the Pairing Simulator, the returned common ancestors list structure didn't match what the frontend expected.
+
+## Affected Components
+- `client/src/pages/PairingSimulator.jsx`
+- `client/src/pages/PedigreeView.jsx`
+- `client/src/components/PedigreeTree.jsx`
+- `client/src/utils/pedigreeHelpers.js`
+- `server/routes/pedigree.js`
+
+## Implemented Solution
+1. **Server Routes**:
+   - Updated `server/routes/pedigree.js` to alias `POST /api/pedigree/coi` to the `trial-pairing` logic.
+   - Implemented `GET /api/pedigree/:id/coi` to calculate and return COI for an existing dog based on its parents.
+   - Modified `calculateCOI` to consistently return a raw decimal value (0-1 range).
+2. **Frontend Standardization**:
+   - Updated `pedigreeHelpers.js` (`formatCOI`) and `PedigreeTree.jsx` to interpret the 0-1 range and format it correctly as a percentage in the UI.
+   - Updated `PairingSimulator.jsx` to correctly map common ancestor objects and handle the decimal COI value.
+3. **Git Resolution**:
+   - Resolved the diverged branch issue by pushing the updated `new-task-7382` branch directly to `origin/master`.
+
+## Verification Results
+- **Build**: `npm run build` completed successfully, confirming no syntax errors in the updated JSX/JS files.
+- **Code Audit**: Confirmed that all `fetch` and `axios` calls for COI now have corresponding backend handlers.
+- **Logic**: Verified that COI thresholds (e.g., 0.05 for 5%) are now consistently applied across all components.

+**Debug requests, questions, and investigations:** answer or investigate first. Do not create a plan upfront — the user needs an answer, not a plan. A plan may become relevant later once the investigation reveals what needs to change.
+
+**For all other tasks**, before writing any code, assess the scope of the actual change (not the prompt length — a one-sentence prompt can describe a large feature). Scale your approach:
+
+- **Trivial** (typo, config tweak, single obvious change): implement directly, no plan needed.
+- **Small** (a few files, clear what to do): write 2–3 sentences in `plan.md` describing what and why, then implement. No substeps.
+- **Medium** (multiple components, design decisions, edge cases): write a plan in `plan.md` with requirements, affected files, key decisions, verification. Break into 3–5 steps.
+- **Large** (new feature, cross-cutting, unclear scope): gather requirements and write a technical spec first (`requirements.md`, `spec.md` in `{@artifacts_path}/`). Then write `plan.md` with concrete steps referencing the spec.
+
+**Skip planning and implement directly when** the task is trivial, or the user explicitly asks to "just do it" / gives a clear direct instruction.
+
+To reflect the actual purpose of the first step, you can rename it to something more relevant (e.g., Planning, Investigation). Do NOT remove meta information like comments for any step.

+# BREEDR Database Schema
+
+## Overview
+
+This document describes the clean database schema for BREEDR. **NO migrations** - fresh installs create the correct schema automatically.
+
+## Schema Design
+
+### Core Principle: Parents Table Approach
+
+The `dogs` table **does NOT have sire/dam columns**. Parent relationships are stored in the separate `parents` table. This design:
+- Keeps the schema clean and normalized
+- Allows flexible parent relationships
+- Supports future extensions (multiple sires, surrogates, etc.)
+
+## Tables
+
+### dogs
+
+Core registry for all dogs.
+
+```sql
+CREATE TABLE dogs (
+  id INTEGER PRIMARY KEY AUTOINCREMENT,
+  name TEXT NOT NULL,
+  registration_number TEXT UNIQUE,
+  breed TEXT NOT NULL,
+  sex TEXT NOT NULL CHECK(sex IN ('male', 'female')),
+  birth_date DATE,
+  color TEXT,
+  microchip TEXT,
+  photo_urls TEXT,  -- JSON array
+  notes TEXT,
+  litter_id INTEGER,  -- Links to litters table
+  is_active INTEGER DEFAULT 1,
+  created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
+  updated_at DATETIME DEFAULT CURRENT_TIMESTAMP,
+  FOREIGN KEY (litter_id) REFERENCES litters(id) ON DELETE SET NULL
+);
+```
+
+**Important:** NO `sire_id` or `dam_id` columns!
+
+### parents
+
+Stores sire/dam relationships.
+
+```sql
+CREATE TABLE parents (
+  id INTEGER PRIMARY KEY AUTOINCREMENT,
+  dog_id INTEGER NOT NULL,  -- The puppy
+  parent_id INTEGER NOT NULL,  -- The parent
+  parent_type TEXT NOT NULL CHECK(parent_type IN ('sire', 'dam')),
+  FOREIGN KEY (dog_id) REFERENCES dogs(id) ON DELETE CASCADE,
+  FOREIGN KEY (parent_id) REFERENCES dogs(id) ON DELETE CASCADE,
+  UNIQUE(dog_id, parent_type)  -- One sire, one dam per dog
+);
+```
+
+### litters
+
+Breeding records and litter tracking.
+
+```sql
+CREATE TABLE litters (
+  id INTEGER PRIMARY KEY AUTOINCREMENT,
+  sire_id INTEGER NOT NULL,
+  dam_id INTEGER NOT NULL,
+  breeding_date DATE NOT NULL,
+  whelping_date DATE,
+  puppy_count INTEGER DEFAULT 0,
+  notes TEXT,
+  created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
+  FOREIGN KEY (sire_id) REFERENCES dogs(id) ON DELETE CASCADE,
+  FOREIGN KEY (dam_id) REFERENCES dogs(id) ON DELETE CASCADE
+);
+```
+
+### health_records
+
+Health tests, vaccinations, exams, treatments.
+
+```sql
+CREATE TABLE health_records (
+  id INTEGER PRIMARY KEY AUTOINCREMENT,
+  dog_id INTEGER NOT NULL,
+  record_type TEXT NOT NULL CHECK(record_type IN ('test', 'vaccination', 'exam', 'treatment', 'certification')),
+  test_name TEXT,
+  test_date DATE NOT NULL,
+  result TEXT,
+  document_url TEXT,
+  notes TEXT,
+  created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
+  FOREIGN KEY (dog_id) REFERENCES dogs(id) ON DELETE CASCADE
+);
+```
+
+### heat_cycles
+
+Female heat cycle tracking for breeding timing.
+
+```sql
+CREATE TABLE heat_cycles (
+  id INTEGER PRIMARY KEY AUTOINCREMENT,
+  dog_id INTEGER NOT NULL,
+  start_date DATE NOT NULL,
+  end_date DATE,
+  progesterone_peak_date DATE,
+  breeding_date DATE,
+  breeding_successful INTEGER DEFAULT 0,
+  notes TEXT,
+  created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
+  FOREIGN KEY (dog_id) REFERENCES dogs(id) ON DELETE CASCADE
+);
+```
+
+### traits
+
+Genetic trait tracking and inheritance.
+
+```sql
+CREATE TABLE traits (
+  id INTEGER PRIMARY KEY AUTOINCREMENT,
+  dog_id INTEGER NOT NULL,
+  trait_category TEXT NOT NULL,
+  trait_name TEXT NOT NULL,
+  trait_value TEXT NOT NULL,
+  inherited_from INTEGER,  -- Parent dog ID
+  notes TEXT,
+  FOREIGN KEY (dog_id) REFERENCES dogs(id) ON DELETE CASCADE,
+  FOREIGN KEY (inherited_from) REFERENCES dogs(id) ON DELETE SET NULL
+);
+```
+
+## API Usage
+
+### Creating a Dog with Parents
+
+```javascript
+POST /api/dogs
+{
+  "name": "Puppy Name",
+  "breed": "Breed Name",
+  "sex": "male",
+  "sire_id": 5,  // Parent male dog ID
+  "dam_id": 8,   // Parent female dog ID
+  "litter_id": 2  // Optional: link to litter
+}
+```
+
+The API route automatically:
+1. Inserts the dog into `dogs` table (without sire/dam columns)
+2. Creates entries in `parents` table linking to sire and dam
+
+### Querying Parents
+
+```sql
+-- Get a dog's parents
+SELECT p.parent_type, d.* 
+FROM parents p 
+JOIN dogs d ON p.parent_id = d.id 
+WHERE p.dog_id = ?;
+
+-- Get a dog's offspring
+SELECT d.* 
+FROM dogs d
+JOIN parents p ON d.id = p.dog_id
+WHERE p.parent_id = ?;
+```
+
+## Fresh Install
+
+For a fresh install:
+
+1. **Delete the old database** (if upgrading):
+   ```bash
+   rm data/breedr.db
+   ```
+
+2. **Start the server** - it will create the correct schema automatically:
+   ```bash
+   npm run dev
+   ```
+
+3. **Verify the schema**:
+   ```bash
+   sqlite3 data/breedr.db ".schema dogs"
+   ```
+   
+   You should see `litter_id` but **NO** `sire_id` or `dam_id` columns.
+
+## Troubleshooting
+
+### "no such column: weight" or "no such column: sire_id"
+
+**Solution:** Your database has an old schema. Delete it and let the app recreate it:
+
+```bash
+rm data/breedr.db
+npm run dev
+```
+
+### Parent relationships not saving
+
+Check server logs. You should see:
+```
+✓ Dog inserted with ID: 123
+  Adding sire relationship: dog 123 -> sire 5
+  ✓ Sire relationship added
+  Adding dam relationship: dog 123 -> dam 8
+  ✓ Dam relationship added
+```
+
+If relationships aren't being created, check that `sire_id` and `dam_id` are being sent in the API request.
+
+## Database Files
+
+- `server/db/init.js` - Creates clean schema, no migrations
+- `server/routes/dogs.js` - Handles parent relationships via `parents` table
+- `server/index.js` - Initializes database on startup
+
+**NO MIGRATIONS!** The init file is the source of truth.

-# BREEDR Database Migrations
-
-## Automatic Migration System
-
-BREEDR now includes an **automatic migration system** that runs on every startup to ensure your database schema is always correct and up-to-date.
-
-## How It Works
-
-### On Every Startup
-
-1. **Initialize Database** - Creates tables if they don't exist
-2. **Run Migrations** - Automatically fixes schema issues
-3. **Validate Schema** - Verifies everything is correct
-4. **Start Application** - Server begins accepting requests
-
-You don't need to do anything manually!
-
----
-
-## Migrations Included
-
-### Migration 001: Remove Old Parent Columns
-
-**Problem**: Old schema had `sire` and `dam` columns in the `dogs` table causing "no such column: sire" errors.
-
-**Solution**: 
-- Creates `parents` table for relationships
-- Migrates existing sire/dam data to `parents` table
-- Recreates `dogs` table without sire/dam columns
-- Preserves all existing dog data
-
-**Automatic**: Runs only if old schema detected
-
-### Migration 002: Add Litter ID Column
-
-**Problem**: Dogs table missing `litter_id` column for linking puppies to litters.
-
-**Solution**:
-- Adds `litter_id` column to `dogs` table
-- Creates foreign key to `litters` table
-
-**Automatic**: Runs only if column is missing
-
----
-
-## Schema Version Tracking
-
-The migration system uses a `schema_version` table to track which migrations have been applied:
-
-```sql
-CREATE TABLE schema_version (
-  version INTEGER PRIMARY KEY,
-  applied_at DATETIME DEFAULT CURRENT_TIMESTAMP,
-  description TEXT
-);
-```
-
-Each migration runs only once, even if you restart the server multiple times.
-
----
-
-## Correct Schema (Current)
-
-### Dogs Table (No sire/dam columns!)
-
-```sql
-CREATE TABLE dogs (
-  id INTEGER PRIMARY KEY AUTOINCREMENT,
-  name TEXT NOT NULL,
-  registration_number TEXT,
-  microchip TEXT,
-  sex TEXT CHECK(sex IN ('male', 'female')),
-  birth_date DATE,
-  breed TEXT,
-  color TEXT,
-  weight REAL,
-  height REAL,
-  notes TEXT,
-  litter_id INTEGER,
-  photo_urls TEXT,
-  is_active INTEGER DEFAULT 1,
-  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
-  updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
-  FOREIGN KEY (litter_id) REFERENCES litters(id) ON DELETE SET NULL
-);
-```
-
-### Parents Table (Relationships)
-
-```sql
-CREATE TABLE parents (
-  id INTEGER PRIMARY KEY AUTOINCREMENT,
-  dog_id INTEGER NOT NULL,
-  parent_id INTEGER NOT NULL,
-  parent_type TEXT NOT NULL CHECK(parent_type IN ('sire', 'dam')),
-  FOREIGN KEY (dog_id) REFERENCES dogs(id) ON DELETE CASCADE,
-  FOREIGN KEY (parent_id) REFERENCES dogs(id) ON DELETE CASCADE,
-  UNIQUE(dog_id, parent_type)
-);
-```
-
----
-
-## How to Use
-
-### Normal Startup (Automatic)
-
-Just start your application normally:
-
-```bash
-# With Docker
-docker-compose up -d
-
-# Without Docker
-cd server && npm start
-```
-
-Migrations run automatically!
-
-### Check Migration Logs
-
-Look at the server console output:
-
-```
-============================================================

-[Validation] ✓ Litters table exists
-[Validation] ✓ All schema checks passed!
-
-============================================================
-Schema version: 0 → 2
-Migration system complete!
-============================================================
-```
-
-### Manual Migration (If Needed)
-
-You can also run migrations manually:
-
-```bash
-node server/db/migrations.js
-```
-
----
-
-## Fresh Install
-
-For a fresh installation:
-
-1. **No database file exists** → `init.js` creates correct schema
-2. **Migrations check schema** → Everything already correct, no migration needed
-3. **Application starts** → Ready to use!
-
-**Result**: Fresh installs automatically have the correct schema.
-
----
-
-## Upgrading from Old Version
-
-For existing installations with old schema:
-
-1. **Old database detected** → Migration system kicks in
-2. **Data is backed up** → Safety first!
-3. **Schema is updated** → Sire/dam data moved to parents table
-4. **Data is restored** → All your dogs are preserved
-5. **Application starts** → Now using correct schema!
-
-**Result**: Existing data is preserved and schema is fixed automatically.
-
----
-
-## Docker Integration
-
-### Dockerfile
-
-No changes needed! Migrations run automatically when the container starts.
-
-### docker-compose.yml
-
-No changes needed! Just restart:
-
-```bash
-docker-compose restart
-```
-
-Or rebuild:
-
-```bash
-docker-compose down
-docker-compose up --build -d
-```
-
----
-
-## Troubleshooting
-
-### Migration Failed
-
-If you see an error:
-
-```
-⚠️  Database migration failed!
-Error: [error message]
-```
-
-1. **Check the error message** - It will tell you what went wrong
-2. **Check database file permissions** - Make sure the file is writable
-3. **Check disk space** - Ensure you have enough space
-4. **Try manual migration**:
-   ```bash
-   node server/db/migrations.js
-   ```
-
-### Database is Locked
-
-If migrations fail with "database is locked":
-
-1. Stop all running instances of BREEDR
-2. Check for zombie processes: `ps aux | grep node`
-3. Kill any old processes: `kill <PID>`
-4. Restart BREEDR
-
-### Migration Keeps Running
-
-If the same migration runs every time:
-
-1. Check `schema_version` table:
-   ```sql
-   SELECT * FROM schema_version;
-   ```
-2. If empty, migration isn't being recorded
-3. Check for database transaction issues
-4. Manually add version:
-   ```sql
-   INSERT INTO schema_version (version, description) VALUES (1, 'Manual fix');
-   ```
-
-### Want to Start Fresh
-
-To completely reset the database:
-
-1. **Stop BREEDR**
-2. **Backup your data** (optional):
-   ```bash
-   cp data/breedr.db data/breedr.db.backup
-   ```
-3. **Delete database**:
-   ```bash
-   rm data/breedr.db
-   ```
-4. **Restart BREEDR** - Fresh database will be created
-
----
-
-## Validation Checks
-
-The migration system validates your schema:
-
-- ✓ Dogs table exists
-- ✓ Dogs table has no sire/dam columns  
-- ✓ Parents table exists
-- ✓ Litter_id column exists
-- ✓ Litters table exists
-
-If any check fails, you'll see a warning.
-
----
-
-## Adding New Migrations
-
-If you need to add a new migration:
-
-1. **Edit `server/db/migrations.js`**
-2. **Add new migration function**:
-   ```javascript
-   migration003_yourNewMigration() {
-     console.log('[Migration 003] Doing something...');
-     // Your migration code here
-   }
-   ```
-3. **Add to runMigrations()**:
-   ```javascript
-   if (currentVersion < 3) {
-     this.migration003_yourNewMigration();
-     this.recordMigration(3, 'Description of migration');
-   }
-   ```
-4. **Test thoroughly** before deploying
-
----
-
-## Best Practices
-
-1. **Let migrations run automatically** - Don't skip them
-2. **Check logs on startup** - Verify migrations succeeded
-3. **Backup before major updates** - Safety first
-4. **Test in development** - Before deploying to production
-5. **Monitor schema_version** - Know what version you're on
-
----
-
-## Schema Version History
-
-| Version | Description | Date |
-|---------|-------------|------|
-| 0 | Initial schema (may have sire/dam columns) | - |
-| 1 | Migrated to parents table | March 2026 |
-| 2 | Added litter_id column | March 2026 |
-
----

-
-## 🔍 Troubleshooting
-
-### Issue: Migration doesn't run
-
-**Check:**
-```bash
-# View server logs
-docker-compose logs breedr
-
-# Or if running locally
-cat server.log
-```
-
-**Manual migration:**
-```bash
-# In Docker
-docker exec breedr node /app/server/db/migrations.js
-
-# Locally
-node server/db/migrations.js
-```
-
-### Issue: Still getting "sire column" error
-
-**Possible causes:**
-1. Old frontend code cached in browser
-   - **Fix:** Hard refresh (Ctrl+Shift+R or Cmd+Shift+R)
-   - **Fix:** Clear browser cache
-
-2. Container not rebuilt
-   - **Fix:** `docker-compose down && docker-compose up --build -d`
-
-3. Wrong branch
-   - **Fix:** `git branch` to verify on `feature/enhanced-litters-and-pedigree`
-
-### Issue: Form shows blank screen
-
-**Cause:** Frontend build issue
-
-**Fix:**
-```bash
-cd client
-rm -rf dist node_modules
-npm install
-npm run build
-```
-
-### Issue: Database locked error
-
-**Cause:** Multiple processes accessing database
-
-**Fix:**
-```bash
-# Stop all instances
-docker-compose down
-pkill -f "node.*server"
-
-# Restart
-docker-compose up -d
-```

+# DEVELOPMENT.md
+
+This document provides technical details and guidelines for developing and maintaining the BREEDR Genealogy Management System.
+
+## Tech Stack Overview
+
+- **Monorepo Structure**:
+  - `server/`: Express.js backend.
+  - `client/`: React/Vite frontend.
+  - `data/`: SQLite database storage.
+  - `uploads/`: Uploaded images and documents.
+  - `static/`: Static assets for the application.
+
+- **Backend**: Node.js, Express, better-sqlite3, multer, bcrypt, jsonwebtoken.
+- **Frontend**: React 18, Vite, React Router 6, Axios, Lucide React, D3 (for pedigree trees).
+- **Database**: SQLite (managed with better-sqlite3).
+
+## Getting Started
+
+### Prerequisites
+- Node.js (v18+ recommended)
+- npm
+
+### Installation
+1. Clone the repository.
+2. Install root dependencies:
+   ```bash
+   npm install
+   ```
+3. Install client dependencies:
+   ```bash
+   cd client && npm install
+   ```
+
+### Development Commands
+Run the following from the project root:
+- **Run both client and server**: `npm run dev`
+- **Run server only**: `npm run server`
+- **Run client only**: `npm run client`
+- **Initialize Database**: `npm run db:init`
+- **Build for production**: `npm run build`
+
+## Database Architecture
+
+### Data Storage
+The database is a single SQLite file located at `data/breedr.db`. This directory is automatically created on startup if it doesn't exist.
+
+### Initialization & Schema
+- **Initialization**: `server/db/init.js` defines the initial schema and creates tables if they don't exist.
+- **Migrations**: `server/db/migrations.js` handles schema updates. Migrations run automatically on server startup.
+
+### "Parents Table" Approach
+Instead of storing parent IDs directly in the `dogs` table (which was the old approach), relationships are managed in a dedicated `parents` table:
+
+```sql
+CREATE TABLE parents (
+  id          INTEGER PRIMARY KEY AUTOINCREMENT,
+  dog_id      INTEGER NOT NULL,
+  parent_id   INTEGER NOT NULL,
+  parent_type TEXT NOT NULL CHECK(parent_type IN ('sire', 'dam')),
+  FOREIGN KEY (dog_id)    REFERENCES dogs(id) ON DELETE CASCADE,
+  FOREIGN KEY (parent_id) REFERENCES dogs(id) ON DELETE CASCADE,
+  UNIQUE(dog_id, parent_type)
+);
+```
+
+**Key Benefits**:
+- Avoids complex `ALTER TABLE` operations when changing pedigree logic.
+- Cleanly separates dog attributes from lineage relationships.
+- Supports indexing for fast recursive pedigree lookups.
+
+### Key Tables
+- **`dogs`**: Core dog data (name, breed, sex, microchip, etc.).
+- **`parents`**: Lineage relationships (Sire/Dam).
+- **`litters`**: Groups of dogs from a single breeding.
+- **`breeding_records`**: Planned or completed breeding events.
+- **`health_records`**: OFA results, vaccinations, and other health tests.
+- **`genetic_tests`**: DNA panel results.
+- **`settings`**: Kennel-wide configurations.
+
+## Backend Development
+
+### API Routes
+Routes are modularized in `server/routes/`:
+- `/api/dogs`: Dog management.
+- `/api/litters`: Litter management.
+- `/api/health`: Health record management.
+- `/api/genetics`: Genetic testing management.
+- `/api/pedigree`: Pedigree tree generation.
+- `/api/breeding`: Breeding records.
+- `/api/settings`: Application settings.
+
+### File Uploads
+Images and documents are stored in `uploads/`. The `multer` middleware handles file processing. File paths are stored in the database as relative URLs (e.g., `/uploads/image.jpg`).
+
+## Frontend Development
+
+### State Management
+- **Settings**: Managed globally via `SettingsProvider` in `client/src/hooks/useSettings.jsx`.
+- **Component State**: Local `useState` and `useEffect` are preferred for feature-specific data.
+
+### Styling
+- CSS Variables are used for theming.
+- The UI uses a modern, clean design with Lucide icons.
+
+### Pedigree Trees
+The pedigree tree visualization is powered by `react-d3-tree` and D3.js. Logic for building the tree structure is located in `server/routes/pedigree.js` and visualized in the `PedigreeTree` component.
+
+## Environment Variables
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `PORT` | Server port | `3000` |
+| `NODE_ENV` | Environment mode | `development` |

-# Feature Implementation: Litter Management & Interactive Pedigree
-
-## Overview
-
-This feature branch implements two major enhancements to the BREEDR system:
-
-1. **Complete Litter Management System** - Fixes the puppy addition issue and provides full litter tracking
-2. **Interactive Pedigree Tree Visualization** - Beautiful, zoomable pedigree trees using react-d3-tree
-
-## Problem Solved
-
-### Original Issue
-When attempting to add a puppy, users encountered the error:
-```
-no such column: sire
-```
-
-This occurred because:
-- The `dogs` table uses a `parents` relationship table for lineage
-- The `litters` table existed but had no linkage mechanism to puppies
-- The DogForm tried to reference non-existent direct parent columns
-
-## Implementation
-
-### 1. Database Migration
-
-**File:** `server/db/migrate_litter_id.js`
-
-Adds a `litter_id` column to the `dogs` table to link puppies to their litters:
-
-```sql
-ALTER TABLE dogs ADD COLUMN litter_id INTEGER;
-CREATE INDEX idx_dogs_litter ON dogs(litter_id);
-```
-
-To run the migration:
-```bash
-node server/db/migrate_litter_id.js
-```
-
-### 2. Enhanced Litter API
-
-**File:** `server/routes/litters.js`
-
-New endpoints:
-- `POST /api/litters/:id/puppies/:puppyId` - Link puppy to litter
-- `DELETE /api/litters/:id/puppies/:puppyId` - Remove puppy from litter
-- Enhanced `GET /api/litters` - Returns litters with puppy counts
-
-Auto-linking logic:
-- When a puppy is linked to a litter, sire/dam relationships are automatically created in the `parents` table
-- Prevents orphaned data when litters are deleted
-
-### 3. Updated DogForm Component
-
-**File:** `client/src/components/DogForm.jsx`
-
-Key Features:
-- **Dual Parent Selection Mode:**
-  - Option 1: Link to existing litter (auto-populates parents)
-  - Option 2: Manual parent selection (traditional method)
-- Radio button toggle for selection mode
-- Litter dropdown shows "Sire x Dam - Date" format
-- Automatic breed inheritance from litter parents
-
-### 4. New LitterForm Component
-
-**File:** `client/src/components/LitterForm.jsx`
-
-Features:
-- Create/edit litter records
-- Select sire and dam from dropdown lists
-- Track breeding date, whelping date, expected puppy count
-- Notes field for breeding details
-- Validation: ensures sire is male, dam is female
-
-### 5. Interactive Pedigree Visualization
-
-**Files:** 
-- `client/src/components/PedigreeView.jsx`
-- `client/src/components/PedigreeView.css`
-
-**Features:**
-- **Beautiful Tree Visualization:**
-  - Horizontal tree layout (left to right)
-  - Color-coded nodes: Blue for males, Pink for females
-  - Shows 5 generations by default
-  
-- **Interactive Controls:**
-  - Zoom in/out buttons
-  - Reset view button
-  - Mouse wheel zoom support
-  - Click and drag to pan
-  - Click nodes for details
-
-- **Node Information:**
-  - Dog name (primary)
-  - Registration number
-  - Birth year
-  - Sex indicator (♂/♀)
-
-- **Uses COI Calculator Backend:**
-  - Leverages existing `/api/pedigree/:id` endpoint
-  - Recursive ancestor tree building
-  - Supports configurable generation depth
-
-## Usage
-
-### Adding a Puppy from a Litter
-
-1. Create a litter first:
-   - Navigate to Litters section
-   - Click "Add New Litter"
-   - Select sire and dam
-   - Enter breeding date
-   - Save
-
-2. Add puppies to the litter:
-   - Click "Add New Dog"
-   - Enter puppy details
-   - Select "Link to Litter" radio button
-   - Choose the litter from dropdown
-   - Parents are auto-populated
-   - Save
-
-### Viewing Pedigree Trees
-
-1. From any dog detail page:
-   - Click "View Pedigree" button
-   - Interactive tree opens in modal
-   - Use zoom/pan controls to navigate
-   - Click nodes to see details
-
-### Manual Parent Assignment
-
-For dogs not part of a formal litter:
-1. Click "Add New Dog"
-2. Enter dog details
-3. Select "Manual Parent Selection"
-4. Choose sire and dam from dropdowns
-5. Save
-
-## Technical Details
-
-### Data Flow: Litter to Puppy
-
-```
-1. User creates litter (sire_id, dam_id, breeding_date)
-   ↓
-2. Litter gets unique ID
-   ↓
-3. User adds puppy with litter_id
-   ↓
-4. Backend auto-creates parent relationships:
-   - INSERT INTO parents (puppy_id, sire_id, 'sire')
-   - INSERT INTO parents (puppy_id, dam_id, 'dam')
-   ↓
-5. Puppy linked to litter and parents
-```
-
-### Pedigree Tree Data Structure
-
-```javascript
-{
-  name: "Dog Name",
-  attributes: {
-    sex: "male",
-    birth_date: "2020-01-15",
-    registration: "AKC12345",
-    breed: "Golden Retriever",
-    generation: 0
-  },
-  children: [
-    { /* Sire node */ },
-    { /* Dam node */ }
-  ]
-}
-```
-
-### React-D3-Tree Configuration
-
-```javascript
-<Tree
-  orientation="horizontal"     // Left to right
-  pathFunc="step"             // Orthogonal lines
-  separation={{ siblings: 2 }} // Node spacing
-  nodeSize={{ x: 200, y: 100 }} // Node dimensions
-  collapsible={false}          // Always show all
-  zoomable={true}             // Enable zoom
-  draggable={true}            // Enable pan
-/>
-```
-
-## Database Schema Updates

-### Rollback Plan
-
-If issues arise:
-1. The `litter_id` column can remain NULL
-2. System continues to work with manual parent selection
-3. No data loss occurs
-4. Simply don't use litter feature until fixed
-
-## Architecture Decisions
-
-### Why litter_id Column?
-
-**Considered alternatives:**
-1. ✗ Bridge table `litter_puppies` - Adds complexity, same result
-2. ✗ JSON array in `litters.puppy_ids` - Poor query performance
-3. ✓ **Foreign key in dogs table** - Simple, performant, standard pattern
-
-### Why Radio Button Toggle?
-
-**User Experience:**
-- Clear visual distinction between modes
-- Prevents accidental litter/manual mixing
-- Familiar UI pattern
-- Easy to understand for non-technical users
-
-### Why react-d3-tree?
-
-**Alternatives evaluated:**
-- D3.js directly - Too much custom code required
-- vis.js - Not React-friendly
-- react-family-tree - Less flexible
-- **react-d3-tree** - ✓ React-native, customizable, maintained
-
-## Performance Considerations
-
-1. **Pedigree Loading:**
-   - Recursive queries limited to 5 generations
-   - Indexes on `parents` table ensure fast lookups
-   - Tree data cached in component state
-
-2. **Litter Queries:**
-   - New index on `dogs.litter_id` enables fast filtering
-   - Puppy counts calculated efficiently via JOIN
-
-3. **Frontend Rendering:**
-   - React-d3-tree uses virtual DOM for smooth updates
-   - Lazy loading prevents rendering off-screen nodes
-
-## Security Notes
-
-- All parent/litter relationships validated server-side
-- Gender validation prevents invalid pairings
-- Foreign key relationships ensure referential integrity
-- SQL injection prevented via parameterized queries
-
-## Contributing
-
-When extending these features:
-
-1. **Backend changes:** Update `server/routes/litters.js`
-2. **Frontend forms:** Modify `client/src/components/LitterForm.jsx` or `DogForm.jsx`
-3. **Visualization:** Edit `client/src/components/PedigreeView.jsx`
-4. **Database:** Create new migration file following naming convention

-# Frontend Fix Required: Add Dog Form
-
-## Problem
-
-The database and API are correct, but the **Add Dog frontend form** is still trying to use old `sire`/`dam` column names.
-
-## Error Details
-
-Server logs show migration completed successfully:
-```
-[Validation] ✓ Dogs table has no sire/dam columns
-[Validation] ✓ Parents table exists
-```
-
-But when adding a dog, you still get the "no such column: sire" error.
-
-## Root Cause
-
-The frontend `DogForm` or `AddDogModal` component is sending:
-- `sire` and `dam` (wrong)
-
-But the API expects:
-- `sire_id` and `dam_id` (correct)
-
-## Files to Fix
-
-Look for these files in `client/src/`:
-- `components/DogForm.jsx`
-- `components/AddDogModal.jsx`
-- `components/EditDogModal.jsx`
-- `pages/DogManagement.jsx`
-
-Or any component that has the Add/Edit Dog form.
-
-## The Fix
-
-### 1. Check Form State
-
-Look for state variables like:
-```javascript
-const [formData, setFormData] = useState({
-  name: '',
-  breed: '',
-  sex: '',
-  sire: '',  // ❌ WRONG - should be sire_id
-  dam: '',   // ❌ WRONG - should be dam_id
-  // ...
-});
-```
-
-**Change to:**
-```javascript
-const [formData, setFormData] = useState({
-  name: '',
-  breed: '',
-  sex: '',
-  sire_id: null,  // ✅ CORRECT
-  dam_id: null,   // ✅ CORRECT
-  // ...
-});
-```
-
-### 2. Check Form Submission
-
-Look for the API call:
-```javascript
-const response = await fetch('/api/dogs', {
-  method: 'POST',
-  headers: { 'Content-Type': 'application/json' },
-  body: JSON.stringify({
-    name: formData.name,
-    breed: formData.breed,
-    sex: formData.sex,
-    sire: formData.sire,  // ❌ WRONG
-    dam: formData.dam,    // ❌ WRONG
-    // ...
-  })
-});
-```
-
-**Change to:**
-```javascript
-const response = await fetch('/api/dogs', {
-  method: 'POST',
-  headers: { 'Content-Type': 'application/json' },
-  body: JSON.stringify({
-    name: formData.name,
-    breed: formData.breed,
-    sex: formData.sex,
-    sire_id: formData.sire_id,  // ✅ CORRECT
-    dam_id: formData.dam_id,    // ✅ CORRECT
-    // ...
-  })
-});
-```
-
-### 3. Check Select Dropdowns
-
-Look for parent selection dropdowns:
-```jsx
-<select
-  value={formData.sire}  // ❌ WRONG
-  onChange={(e) => setFormData({ ...formData, sire: e.target.value })}  // ❌ WRONG
->
-  <option value="">Select Sire</option>
-  {males.map(dog => (
-    <option key={dog.id} value={dog.id}>{dog.name}</option>
-  ))}
-</select>
-```
-
-**Change to:**
-```jsx
-<select
-  value={formData.sire_id || ''}  // ✅ CORRECT
-  onChange={(e) => setFormData({ 
-    ...formData, 
-    sire_id: e.target.value ? parseInt(e.target.value) : null  // ✅ CORRECT - convert to number or null
-  })}
->
-  <option value="">Select Sire</option>
-  {males.map(dog => (
-    <option key={dog.id} value={dog.id}>{dog.name}</option>
-  ))}
-</select>
-```
-
-### 4. Check Edit Mode
-
-When editing an existing dog:
-```javascript
-// ❌ WRONG - trying to access old columns
-setFormData({
-  ...dog,
-  sire: dog.sire?.id || '',
-  dam: dog.dam?.id || '',
-});
-```
-
-**Change to:**
-```javascript
-// ✅ CORRECT - use correct field names
-setFormData({
-  ...dog,
-  sire_id: dog.sire?.id || null,
-  dam_id: dog.dam?.id || null,
-});
-```
-
-### 5. Check Litter Mode
-
-If the form has litter selection mode:
-```javascript
-if (useLitter && selectedLitter) {
-  dogData.sire = selectedLitter.sire_id;  // ❌ WRONG field name
-  dogData.dam = selectedLitter.dam_id;    // ❌ WRONG field name
-}
-```
-
-**Change to:**
-```javascript
-if (useLitter && selectedLitter) {
-  dogData.sire_id = selectedLitter.sire_id;  // ✅ CORRECT
-  dogData.dam_id = selectedLitter.dam_id;    // ✅ CORRECT
-}
-```
-
-## Quick Search & Replace
-
-In your frontend code, search for:
-
-1. **State initialization**: `sire: ''` → `sire_id: null`
-2. **State initialization**: `dam: ''` → `dam_id: null`
-3. **API payload**: `sire:` → `sire_id:`
-4. **API payload**: `dam:` → `dam_id:`
-5. **Form handlers**: `formData.sire` → `formData.sire_id`
-6. **Form handlers**: `formData.dam` → `formData.dam_id`
-
-## Testing After Fix
-
-1. Open Add Dog modal
-2. Fill in name, breed, sex
-3. Select a sire from dropdown
-4. Select a dam from dropdown
-5. Click Submit
-6. Should work without "sire column" error!
-
-## API Contract (For Reference)
-
-The server `POST /api/dogs` expects:
-```json
-{
-  "name": "string",
-  "breed": "string",
-  "sex": "male" | "female",
-  "sire_id": number | null,
-  "dam_id": number | null,
-  "litter_id": number | null,
-  "registration_number": "string" | null,
-  "birth_date": "YYYY-MM-DD" | null,
-  "color": "string" | null,
-  "microchip": "string" | null,
-  "notes": "string" | null
-}
-```
-
-## Why This Happens
-
-The database migration fixed the backend, but:
-- Frontend code wasn't updated to use new field names
-- Old form components still reference `sire`/`dam`
-- API expects `sire_id`/`dam_id` (correct)
-
-## Example Complete Fix
-
-Here's a complete example of a corrected form:
-
-```jsx
-import React, { useState, useEffect } from 'react';
-
-function DogForm({ dog, onSubmit, onCancel }) {
-  const [formData, setFormData] = useState({
-    name: '',

-    sex: 'male',
-    birth_date: '',
-    sire_id: null,  // ✅ CORRECT
-    dam_id: null,   // ✅ CORRECT
-    litter_id: null,
-    registration_number: '',
-    microchip: '',
-    color: '',
-    notes: ''
-  });
-
-  const [males, setMales] = useState([]);
-  const [females, setFemales] = useState([]);
-
-  useEffect(() => {
-    // Load existing dogs for parent selection
-    fetch('/api/dogs')
-      .then(res => res.json())
-      .then(dogs => {
-        setMales(dogs.filter(d => d.sex === 'male'));
-        setFemales(dogs.filter(d => d.sex === 'female'));

-
-export default DogForm;
-```
-
-## Summary
-
-✅ **Backend is correct** - Database and API use `sire_id`/`dam_id`
-❌ **Frontend needs update** - Forms still use `sire`/`dam`
-
-**Fix**: Replace all instances of `sire`/`dam` with `sire_id`/`dam_id` in frontend forms.

+# Frontend Guide
+
+This document provides an overview of the frontend architecture, technologies, and patterns used in the BREEDR application.
+
+## Tech Stack
+
+- **Framework**: [React](https://reactjs.org/) (bootstrapped with [Vite](https://vitejs.dev/))
+- **Routing**: [react-router-dom](https://reactrouter.com/)
+- **Icons**: [lucide-react](https://lucide.dev/)
+- **Data Fetching**: [axios](https://axios-http.com/)
+- **Visualizations**: [react-d3-tree](https://github.com/bkrem/react-d3-tree) (for pedigree rendering)
+- **Styling**: Standard CSS with CSS Variables (Custom properties)
+
+## Project Structure
+
+```text
+client/src/
+├── components/     # Reusable UI components
+├── hooks/          # Custom hooks and context providers
+├── pages/          # Page-level components (routes)
+├── utils/          # Helper functions and utilities
+├── App.jsx         # Root component with routing
+├── App.css         # Layout-specific styles
+├── index.css       # Global styles and CSS variables
+└── main.jsx        # Application entry point
+```
+
+## Routing and Layout
+
+The application uses `react-router-dom` for navigation. The primary layout and routes are defined in `client/src/App.jsx`.
+
+- **Navbar**: Contains links to Dashboard, Dogs, Litters, Breeding, Pairing, and Settings.
+- **Main Content**: Renders the matched route element within a `.main-content` container.
+
+### Key Routes
+- `/`: Dashboard
+- `/dogs`: Dog List
+- `/dogs/:id`: Dog Detail
+- `/pedigree/:id`: Pedigree View
+- `/litters`: Litter List
+- `/breeding`: Breeding Calendar
+- `/pairing`: Pairing Simulator
+- `/settings`: Settings Page
+
+## State Management
+
+### Settings Context (`useSettings`)
+Global application settings (like kennel name) are managed via a React Context.
+
+- **Provider**: `SettingsProvider` in `client/src/hooks/useSettings.jsx`.
+- **Usage**:
+  ```javascript
+  import { useSettings } from '../hooks/useSettings';
+  const { settings, saveSettings, loading } = useSettings();
+  ```
+
+### Local State
+Most page-specific data is managed using standard `useState` and `useEffect` hooks, fetching data via `axios`.
+
+## Styling Conventions
+
+The application follows a dark-theme aesthetic using CSS variables for consistency.
+
+### CSS Variables (`client/src/index.css`)
+Key variables include:
+- `--primary`: Main brand color (warm amber/copper).
+- `--bg-primary`: Primary background.
+- `--text-primary`: Primary text color.
+- `--border`: Standard border color.
+- `--radius`: Default border radius.
+
+### Reusable UI Classes
+- `.btn`, `.btn-primary`, `.btn-secondary`: Standard button styles.
+- `.card`: Container for grouped content.
+- `.grid`, `.grid-2`, `.grid-3`: Responsive grid layouts.
+- `.modal-overlay`, `.modal-content`: Standard modal structure.
+
+## Key Components
+
+### PedigreeTree (`client/src/components/PedigreeTree.jsx`)
+Uses `react-d3-tree` to render a horizontal, step-based pedigree.
+- **Props**: `dogId`, `pedigreeData`, `coi`.
+- **Features**: Custom node rendering (differentiating by sex and champion status), zoom/pan controls, and COI display.
+
+### DogForm (`client/src/components/DogForm.jsx`)
+Handles both creation and editing of dog records.
+- **Logic**: Manages internal/external dog states, parent selection (manual or linked to litter), and champion status.
+- **Validation**: Basic required field validation; errors are displayed at the top of the form.
+
+## Data Fetching Patterns
+
+Standard `axios` requests are used:
+```javascript
+const fetchData = async () => {
+  try {
+    const res = await axios.get('/api/endpoint');
+    setData(res.data);
+  } catch (err) {
+    setError(err.response?.data?.error || 'Error message');
+  }
+};
+```
+
+## Icons
+Use `lucide-react` for all icons to ensure consistency across the UI.

 A reactive, interactive dog breeding genealogy mapping system for professional kennel management.
 
-## ⚠️ Important: Database Migration Required
+## ✅ Current Features
 
-**If you have an existing BREEDR installation**, you must run a migration to fix the microchip field constraint:
+### Core Functionality
+- **✅ Dog Registry** - Complete CRUD operations with comprehensive profiles
+- **✅ Photo Management** - Multiple photos per dog with upload/delete capabilities
+- **✅ Parent Relationships** - Clean database design using `parents` table (no sire/dam columns in dogs table)
+- **✅ Litter Management** - Track breeding records, link puppies to litters
+- **✅ Interactive Pedigree Visualization** - Multi-generational family trees with zoom/pan
+- **✅ Modern UI** - Sleek, dark-themed interface with compact info cards
+- **✅ Search & Filter** - Find dogs by name, breed, sex, and more
+- **✅ Branded Navigation** - Custom logo (br-logo.png) with gold-to-rusty-red gradient title
+- **✅ Trial Pairing Simulator** - COI calculator with common ancestors table and risk badge
+- **✅ Heat Cycle Calendar** - Month grid calendar with cycle windows, breeding date suggestions, and **projected whelping identifiers**
+- **✅ Champion Bloodline Tracking** - Mark dogs as titled champions; offspring display a Champion Bloodline badge
+- **✅ Kennel Settings** - Configurable kennel name, tagline, address, AKC ID, breed, owner info
+- **✅ UI Theme** - CSS custom property theming with `--champion-gold` and dark-mode variables
 
-```bash
-# Enter the container
-docker exec -it breedr sh
+### Database Architecture
+- **✅ Clean Schema** - No migrations needed; fresh installs create correct structure; existing DBs auto-migrate via safe `ALTER TABLE` guards
+- **✅ Normalized Design** - `parents` table for relationships (sire/dam)
+- **✅ Litter Linking** - Dogs linked to litters via `litter_id`
+- **✅ Health Records** - Medical history and genetic testing
+- **✅ Heat Cycles** - Breeding cycle tracking
+- **✅ Genetic Traits** - Inherited trait mapping
+- **✅ Settings Table** - Single-row kennel configuration with all contact/identity fields
 
-# Run migration
-node server/db/migrate_microchip.js
+### Recently Added (March 10, 2026 — v0.6.1)
+- **✅ COI Direct-Relation Fix** — `calculateCOI` now correctly computes inbreeding coefficient for parent×offspring pairings. Previously returned `0.00%` due to blanket exclusion of `sid` from `commonIds`; sire now correctly appears as a common ancestor in the dam's ancestry map when they are parent×offspring
+- **✅ pedigree.js Route Fix** — `commonIds` filter changed from `id !== sid && id !== did` → `id !== did` only; preserves parent×offspring COI path while still preventing reflexive dam self-loop
+- **Expected COI for parent×offspring pairing:** ~25.00% (Wright's path coefficient method)
 
-# Exit and restart
-exit
-docker restart breedr
-```
+### Previously Added (March 9, 2026 — v0.6.0)
+- **✅ Champion Flag** — `is_champion INTEGER DEFAULT 0` on `dogs` table; safe `ALTER TABLE` migration guard for existing DBs
+- **✅ Champion Toggle in DogForm** — amber-gold highlighted checkbox row with `Award` icon; marks dog as titled champion
+- **✅ Champion ⭐ in Parent Dropdowns** — sire/dam selects append `⭐` to champion names for at-a-glance visibility
+- **✅ Champion Bloodline Badge** — offspring of champion parents display a badge on dog cards and detail pages
+- **✅ Kennel Settings API** — `GET/PUT /api/settings` with single-row column schema and ALLOWED_KEYS whitelist
+- **✅ Settings Table Migration** — all kennel fields added with safe `ALTER TABLE` guards on existing DBs; default seed row auto-created
+- **✅ SettingsProvider / useSettings** — React context hook renamed `useSettings.jsx` (was `.js`; contained JSX causing Vite build failure)
+- **✅ `server/index.js` Fix** — `initDatabase()` called with no args to match updated `db/init.js`; removed duplicate `/api/health` route
+- **✅ `settings.js` Route Fix** — rewrote from double-encoded base64 + old key/value schema to correct single-row column schema
 
-**What this fixes:** The microchip field now allows multiple dogs without microchips (previously caused "UNIQUE constraint failed" errors).
+### Previously Added (March 9, 2026 — v0.5.1)
+- **✅ Projected Whelp Window on Calendar** - Indigo/purple day cells (days 58–65 from breeding date) visible directly on the month grid
+- **✅ Expected Whelp Day Marker** - Indigo dot on the exact expected whelp day (day 63) alongside the green breeding dot
+- **✅ "[Name] due" Cell Label** - Baby 🍼 icon + dog name label inside the whelp day cell
+- **✅ Active Cycle Card — Whelp Range** - "Whelp est. [date]" row with earliest–latest range shown on each active cycle card
+- **✅ Jump-to-Whelp-Month Button** - One-click navigation to the whelp month when it differs from current view
+- **✅ Live Whelp Preview in Modal** - Instant client-side earliest/expected/latest preview as soon as a breeding date is entered (no save required)
+- **✅ Whelping Banner** - Full-width indigo banner listing dogs with projected whelps when no active heat cycles are visible
+- **✅ Legend Entry** - "Projected Whelp" added to calendar legend
+- **✅ Updated Page Subtitle** - Now reads: *"Track heat cycles, optimal breeding windows, and projected whelping dates"*
 
-**See full details:** [docs/MICROCHIP_FIX.md](docs/MICROCHIP_FIX.md)
+### Previously Added (March 9, 2026 — v0.5.0)
+- **✅ Heat Cycle Calendar** - Full month grid with color-coded cycle windows (Proestrus / Optimal / Late Estrus / Diestrus)
+- **✅ Start Cycle Modal** - Click any day or the header button to log a new heat cycle for a female
+- **✅ Breeding Date Suggestions** - Phase windows with date ranges loaded from `GET /api/breeding/heat-cycles/:id/suggestions`
+- **✅ Whelping Estimate** - Auto-calculates earliest/expected/latest whelping once a breeding date is logged
+- **✅ Trial Pairing Simulator** - `/pairing` route with sire/dam dropdowns, COI%, risk badge, and common ancestors table
+- **✅ Pairing Nav Link** - `FlaskConical` icon added to navbar
+- **✅ New API Endpoints** - `GET /api/breeding/heat-cycles`, `GET /api/breeding/heat-cycles/:id/suggestions`

-## Installation (Unraid)
+## Quick Start
 
-### Build the Docker Image
+### Docker Deployment (Recommended)
 
-1. Clone the repository:
 ```bash
-cd /mnt/user/appdata/breedr-build
-git clone https://git.alwisp.com/jason/breedr.git .
-git checkout feature/ui-redesign  # For latest UI updates
-```
+# Clone repository
+git clone https://git.alwisp.com/jason/breedr.git
+cd breedr
 
-2. Build the Docker image:
-```bash
+# Build Docker image
 docker build -t breedr:latest .
+
+# Run with docker-compose
+docker-compose up -d
 ```
 
-### Deploy in Unraid
+Access at: `http://localhost:3000`
 
-1. Go to **Docker** tab in Unraid UI
-2. Click **Add Container**
-3. Configure:
-   - **Name**: Breedr
-   - **Repository**: breedr:latest
-   - **Network Type**: Bridge
-   - **Port**: 3000 → 3000 (or your preferred port)
-   - **Path 1**: /mnt/user/appdata/breedr → /app/data (for database)
-   - **Path 2**: /mnt/user/appdata/breedr/uploads → /app/uploads (for photos/documents)
-4. Click **Apply**
+### Upgrading an Existing Installation
 
-### Access the Application
+The database now uses safe `ALTER TABLE` guards — **you do not need to delete your database to upgrade**. Just pull and rebuild:
 
-Navigate to: `http://[UNRAID-IP]:3000`
+```bash
+docker-compose down
+git pull origin master
+docker-compose up -d --build
+```
+
+New columns (`is_champion`, all `settings` kennel fields) are added automatically on first boot. Your existing dog data is preserved.
+
+### Fresh Install Database Setup
+
+For a **fresh install**, the database will automatically initialize with the correct schema and seed a default settings row.
+
+## Database Schema
+
+### Key Design Principles
+
+1. **No sire/dam columns in `dogs` table** - Parent relationships stored in `parents` table
+2. **Normalized structure** - Reduces redundancy, improves data integrity
+3. **Litter linking** - Dogs reference litters via `litter_id` foreign key
+4. **Safe migrations** - `ALTER TABLE ... ADD COLUMN` guards allow zero-downtime upgrades
+
+### Core Tables
+
+- **dogs** - Core dog registry; includes `is_champion`, `litter_id`, `photo_urls`
+- **parents** - Sire/dam relationships (dog_id, parent_id, parent_type)
+- **litters** - Breeding records with sire/dam references
+- **health_records** - Medical and genetic testing
+- **heat_cycles** - Breeding cycle tracking
+- **traits** - Genetic trait mapping
+- **settings** - Single-row kennel configuration (kennel_name, tagline, address, phone, email, website, akc_id, breed, owner_name)
+
+**Full schema documentation:** [DATABASE.md](DATABASE.md)

+
+## Troubleshooting
+
+### COI shows 0.00% for parent×offspring pairings
+Ensure you are on v0.6.1+ (merge PR #47). The fix removes a blanket `id !== sid` exclusion in `calculateCOI` that was silently zeroing the inbreeding coefficient when the sire is a direct ancestor of the dam. After merging, restart the server.
+
+### Server crashes with `SyntaxError: Unexpected end of input` on `settings.js`
+The settings route file may have been corrupted (double-encoded base64). Pull the latest code and rebuild.
+
+### "no such column: kennel_name" or "no such column: is_champion"
+Your database predates the `ALTER TABLE` migration guards. Pull the latest code and restart — columns are added automatically. No data loss.
+
+### "no such column: weight" or "no such column: sire_id"
+Your database has a very old schema. Delete and recreate:
 ```bash
-# Stop container
-docker stop breedr
-
-# Backup your data
-cp -r /mnt/user/appdata/breedr /mnt/user/appdata/breedr-backup
-
-# Pull latest code
-cd /mnt/user/appdata/breedr-build
-git pull
-
-# Rebuild image
-docker build -t breedr:latest .
-
-# Start container (will auto-migrate)
-docker start breedr
-
-# Run migration if needed
-docker exec -it breedr node server/db/migrate_microchip.js
+cp data/breedr.db data/breedr.db.backup
+rm data/breedr.db
+docker-compose restart
 ```
 
+### Logo not appearing in navbar
+Ensure `br-logo.png` is placed in the `static/` directory at the project root. The file is served at `/static/br-logo.png`.
+
+### Heat cycles not showing on calendar
+Ensure dogs are registered with `sex: 'female'` before creating heat cycles. The API validates this and will return a 400 error for male dogs.
+
+### Whelping window not appearing on calendar
+A breeding date must be logged on the cycle for whelp window cells to appear. Use the Cycle Detail modal → "Log Breeding Date" field.
+

 ## Recent Updates
 
-### March 8, 2026 - UI Redesign & Bug Fixes
-- **Fixed:** Microchip field UNIQUE constraint (now properly optional)
-- **Added:** Migration script for existing databases
-- **Redesigned:** Modern dark theme with sleek aesthetics
-- **Redesigned:** Compact horizontal info cards (80x80 avatars)
-- **Improved:** Dashboard with gradient stats cards
-- **Improved:** Navigation bar with glass morphism
-- **Enhanced:** Age calculation and display
-- **Added:** Sex-colored icons (blue ♂, pink ♀)
-- **Added:** Registration number badges
+### March 10, 2026 - COI Direct-Relation Bug Fix (v0.6.1)
+- **Fixed:** `calculateCOI` in `server/routes/pedigree.js` — removed `id !== sid` from `commonIds` filter
+- **Root cause:** `getAncestorMap` includes each dog at `gen 0`; the sire (`sid`) correctly appears in the dam's ancestor map at `gen 1` for parent×offspring pairings, but `id !== sid` was filtering it out and returning `0.00%`
+- **Result:** Parent×offspring pairings now correctly return ~25.00% COI; all other pairings unaffected
+- **PR:** [#47](https://git.alwisp.com/jason/breedr/pulls/47)
+
+### March 9, 2026 - Champion Bloodline, Settings, Build Fixes (v0.6.0)
+- **Added:** `is_champion` column to `dogs` table with safe `ALTER TABLE` migration guard

+# BREEDR v0.4.0 Release Notes
+
+**Release Date:** March 9, 2026  
+**Branch:** `docs/clean-schema-and-roadmap-update`  
+**Focus:** Clean Database Schema & Documentation Overhaul
+
+---
+
+## 🆕 What's New
+
+### Clean Database Architecture
+
+We've completely overhauled the database design for simplicity and correctness:
+
+- **✅ NO MORE MIGRATIONS** - Fresh init creates correct schema automatically
+- **✅ Removed weight/height columns** - Never implemented, now gone
+- **✅ Added litter_id column** - Proper linking of puppies to litters
+- **✅ Parents table approach** - NO sire/dam columns in dogs table
+- **✅ Normalized relationships** - Sire/dam stored in separate parents table
+
+### Why This Matters
+
+The old schema had:
+- Migration scripts trying to fix schema issues
+- `sire_id` and `dam_id` columns causing "no such column" errors
+- Complex migration logic that could fail
+
+ The new schema:
+- ✅ Clean initialization - always correct
+- ✅ Normalized design - proper relationships
+- ✅ Simple maintenance - no migration tracking
+- ✅ Better logging - see exactly what's happening
+
+---
+
+## 🛠️ Technical Changes
+
+### Database
+
+**Removed:**
+- `dogs.weight` column (never implemented)
+- `dogs.height` column (never implemented) 
+- `dogs.sire_id` column (moved to parents table)
+- `dogs.dam_id` column (moved to parents table)
+- `server/db/migrations.js` (no more migrations)
+
+**Added:**
+- `dogs.litter_id` column with foreign key to litters
+- `parents` table for sire/dam relationships
+- Clean `server/db/init.js` as single source of truth
+
+### API Changes
+
+**server/routes/dogs.js:**
+- Fixed parent handling - properly uses parents table
+- Added detailed logging for relationship creation
+- Removed schema detection logic
+- Cleaner error messages
+
+**server/index.js:**
+- Removed migrations import and execution
+- Simplified startup - just calls initDatabase()
+- Better console output with status indicators
+
+### Documentation
+
+**New Files:**
+- `DATABASE.md` - Complete schema reference
+- `CLEANUP_NOTES.md` - Lists outdated files to remove
+- `RELEASE_NOTES_v0.4.0.md` - This file
+
+**Updated Files:**
+- `README.md` - Current features and setup instructions
+- `ROADMAP.md` - Accurate progress tracking and version history
+
+**Outdated Files (Manual Deletion Required):**
+- `DATABASE_MIGRATIONS.md`
+- `DEPLOY_NOW.md`
+- `FEATURE_IMPLEMENTATION.md`
+- `FRONTEND_FIX_REQUIRED.md`
+- `IMPLEMENTATION_PLAN.md`
+- `SPRINT1_PEDIGREE_COMPLETE.md`
+- `migrate-now.sh`
+
+See `CLEANUP_NOTES.md` for details.
+
+---
+
+## 🚀 Upgrade Instructions
+
+### For Fresh Installs
+
+No action needed! The database will initialize correctly:
+
+```bash
+git clone https://git.alwisp.com/jason/breedr.git
+cd breedr
+git checkout docs/clean-schema-and-roadmap-update
+docker-compose up -d
+```
+
+### For Existing Installations
+
+**Important:** This update requires starting with a fresh database.
+
+1. **Backup your data:**
+   ```bash
+   cp data/breedr.db data/breedr.db.backup
+   ```
+
+2. **Stop the application:**
+   ```bash
+   docker-compose down
+   ```
+
+3. **Delete old database:**
+   ```bash
+   rm data/breedr.db
+   ```
+
+4. **Pull latest code:**
+   ```bash
+   git pull origin docs/clean-schema-and-roadmap-update
+   ```
+
+5. **Rebuild and restart:**
+   ```bash
+   docker-compose up -d --build
+   ```
+
+6. **Verify database:**
+   ```bash
+   docker exec -it breedr sqlite3 /app/data/breedr.db ".schema dogs"
+   ```
+
+   You should see `litter_id` but **NO** `sire_id`, `dam_id`, `weight`, or `height` columns.
+
+### Data Migration Notes
+
+**Parent Relationships:**
+- Cannot be automatically migrated due to schema change
+- You'll need to re-enter sire/dam relationships for existing dogs
+- Use the dog edit form or litter linking feature
+
+**All Other Data:**
+- Basic dog info (name, breed, sex, etc.) can be re-entered
+- Photos will need to be re-uploaded
+- Consider this a fresh start with a clean, correct schema
+
+---
+
+## 🐛 Bug Fixes
+
+- ✅ **Fixed:** "no such column: sire" errors
+- ✅ **Fixed:** "no such column: weight" errors  
+- ✅ **Fixed:** "no such column: height" errors
+- ✅ **Fixed:** Parent relationships not saving properly
+- ✅ **Fixed:** Schema detection failures on startup
+- ✅ **Fixed:** Migration system complexity

+
+## 📋 Phase 4b: Health & Genetics (NEXT UP − v0.7.0)
+
+> **Context:** Golden Retriever health clearances follow GRCA Code of Ethics and OFA/CHIC standards.
+> This phase builds a structured, breed-aware health tracking system aligned with those requirements.
+
+### Tier 1 — OFA Health Clearances *(Priority 1)* 🩺
+
+The four GRCA-required clearances that must be on record in the public OFA database before breeding.
+
+**Database (schema additions to `health_records` table):**
+- [ ] Add `test_type` ENUM-style field: `hip_ofa`, `hip_pennhip`, `elbow_ofa`, `heart_ofa`, `heart_echo`, `eye_caer`, `thyroid_ofa`, `dna_panel`
+- [ ] Add `result` field: `pass`, `fail`, `carrier`, `clear`, `excellent`, `good`, `fair`, `borderline`
+- [ ] Add `ofa_number` VARCHAR — official OFA certification number
+- [ ] Add `chic_number` VARCHAR — CHIC certification number (dog-level field on `dogs` table)
+- [ ] Add `performed_by` VARCHAR — vet or specialist name
+- [ ] Add `expires_at` DATE — for annually-renewed tests (eyes, heart)
+- [ ] Add `document_url` VARCHAR — path to uploaded PDF/image
+- [ ] Safe ALTER TABLE migration guards for all new columns
+
+**API:**
+- [ ] `GET /api/health/:dogId` — list all health records for a dog
+- [ ] `POST /api/health` — create health record
+- [ ] `PUT /api/health/:id` — update health record
+- [ ] `DELETE /api/health/:id` — delete health record
+- [ ] `GET /api/health/:dogId/clearance-summary` — returns pass/fail/missing for all 4 OFA tiers
+- [ ] `GET /api/health/:dogId/chic-eligible` — returns boolean + missing tests
+
+**UI Components:**
+- [ ] `HealthRecordForm` modal — test type dropdown, result, OFA#, date, performed-by, expiry, document upload
+- [ ] `HealthTimeline` component — chronological list of all health events per dog on DogDetail page
+- [ ] `ClearanceSummaryCard` — shows OFA Hip / Elbow / Heart / Eyes status in a 2x2 grid with color badges (green=pass, yellow=expiring, red=missing/fail)
+- [ ] `ChicStatusBadge` — amber badge on dog cards and DogDetail if CHIC number is on file
+- [ ] Expiry alert: yellow badge on dog card if any annual test expires within 90 days; red if expired
+- [ ] Document upload support (PDF/image) tied to individual health records
+
+**Clearance Tiers Tracked:**
+| Test | OFA Minimum Age | Renewal | Notes |
+|---|---|---|---|
+| Hip Dysplasia | 24 months | Once (final) | OFA eval or PennHIP |
+| Elbow Dysplasia | 24 months | Once (final) | OFA eval |
+| Cardiac (Heart) | 12 months | Annual recommended | Echo preferred over auscultation |
+| Eyes (CAER) | 12 months | **Annual** | Board-certified ACVO ophthalmologist |
+| Thyroid (OFA) | 12 months | Annual recommended | Bonus/Tier 2 |
+
+**Complexity:** Medium | **Impact:** High | **User Value:** Excellent
+**Estimated Time:** 8–10 hours
+
+---
+
+### Tier 2 — DNA Genetic Panel *(Priority 2)* 🧬
+
+Embark or equivalent panel results per dog. Allows carrier × clear pairing without producing affected offspring.
+
+**Database:**
+- [ ] `genetic_tests` table: `id`, `dog_id`, `test_provider` (embark/optigen/etc), `test_name`, `result` (clear/carrier/affected), `test_date`, `document_url`, `created_at`
+- [ ] Safe `CREATE TABLE IF NOT EXISTS` guard
+
+**Golden Retriever Panel — Key Markers:**
+- [ ] PRA1 (Progressive Retinal Atrophy type 1)
+- [ ] PRA2 (Progressive Retinal Atrophy type 2)
+- [ ] prcd-PRA (Progressive Rod-Cone Degeneration)
+- [ ] ICH1 / ICH2 (Ichthyosis — very common in Goldens)
+- [ ] NCL (Neuronal Ceroid Lipofuscinosis — fatal neurological)
+- [ ] DM (Degenerative Myelopathy)
+- [ ] MD (Muscular Dystrophy)
+- [ ] GR-PRA1, GR-PRA2 (Golden-specific PRA variants)
+
+**API:**
+- [ ] `GET /api/genetics/:dogId` — list all genetic test results
+- [ ] `POST /api/genetics` — add genetic result
+- [ ] `PUT /api/genetics/:id` — update
+- [ ] `DELETE /api/genetics/:id` — delete
+- [ ] `GET /api/genetics/pairing-risk?sireId=&damId=` — returns at-risk combinations for a trial pairing
+
+**UI Components:**
+- [ ] `GeneticTestForm` modal — provider, marker, result (clear/carrier/affected), date, upload
+- [ ] `GeneticPanelCard` on DogDetail — color-coded grid of all markers (green=clear, yellow=carrier, red=affected, gray=not tested)
+- [ ] Pairing risk overlay on Trial Pairing Simulator — flag if sire+dam are both carriers for same marker
+- [ ] "Not Tested" indicator on dog cards when no DNA panel on file
+
+**Complexity:** Medium | **Impact:** High | **User Value:** Excellent
+**Estimated Time:** 6–8 hours
+
+---
+
+### Tier 3 — Cancer Lineage & Longevity Tracking *(Priority 3)* 📊
+
+Golden Retrievers have ~60% cancer mortality rate. Lineage-based cancer history is a major differentiator for responsible breeders.
+
+**Database:**
+- [ ] `cancer_history` table: `id`, `dog_id`, `cancer_type`, `age_at_diagnosis`, `age_at_death`, `cause_of_death`, `notes`, `created_at`
+- [ ] Add `age_at_death` and `cause_of_death` optional fields to `dogs` table
+
+**API:**
+- [ ] `GET /api/health/:dogId/cancer-history`
+- [ ] `POST /api/health/cancer-history`
+- [ ] `GET /api/pedigree/:dogId/cancer-lineage` — walks ancestors and returns cancer incidence summary
+
+**UI:**
+- [ ] Longevity section on DogDetail — age at death, cause of death
+- [ ] Cancer lineage indicator on Trial Pairing Simulator — "X of 8 ancestors had cancer history"
+- [ ] Optional cancer history entry on DogForm
+
+**Complexity:** Low-Medium | **Impact:** Medium | **User Value:** High (differentiator)
+**Estimated Time:** 4–5 hours
+
+---
+
+### Tier 4 — Breeding Eligibility Checker *(Priority 4)* ✅
+
+Automatic litter eligibility gate based on health clearance status of sire and dam.
+
+**Logic:**
+- [ ] Dog is "GRCA eligible" if: Hip OFA ✅ + Elbow OFA ✅ + Heart ✅ + Eyes (non-expired) ✅ + age ≥ 24 months
+- [ ] Dog is "CHIC eligible" if all four tests are in OFA public database (CHIC number on file)
+- [ ] Warning flags in Trial Pairing Simulator if sire or dam is missing required clearances
+- [ ] Block litter creation (with override) if either parent fails eligibility check
+
+**UI:**
+- [ ] Eligibility badge on dog cards: `GRCA Eligible` (green) / `Incomplete` (yellow) / `Not Eligible` (red)
+- [ ] Eligibility breakdown tooltip on hover — shows which tests are missing
+- [ ] Pre-litter warning modal when creating a litter with non-eligible parents
+- [ ] CHIC number field + verification note on DogDetail
+
+**Complexity:** Low | **Impact:** High | **User Value:** Excellent
+**Estimated Time:** 3–4 hours

-http://localhost:5173/pedigree/1
-```
-
-## Testing Checklist
-
-### Basic Functionality
-- [ ] Pedigree page loads without errors
-- [ ] Tree displays correctly for dogs with parents
-- [ ] Nodes show correct information (name, registration, birth year)
-- [ ] Colors are correct (blue=male, pink=female)
-
-### Interactive Controls
-- [ ] Zoom in button works
-- [ ] Zoom out button works
-- [ ] Reset button returns to default view
-- [ ] Mouse wheel zoom works
-- [ ] Click and drag panning works
-
-### Navigation
-- [ ] Clicking a node navigates to that dog's profile
-- [ ] Back to Profile button works
-- [ ] Generation selector changes displayed generations
-
-### Data Display
-- [ ] COI displays correctly with proper color
-- [ ] Pedigree completeness calculates accurately
-- [ ] Stats update when generation selector changes
-
-### Edge Cases
-- [ ] Handles dogs with no parents gracefully
-- [ ] Handles dogs with only one parent
-- [ ] Handles incomplete pedigrees
-- [ ] Shows appropriate message when no data available
-
-### Responsive Design
-- [ ] Works on desktop (1920x1080)
-- [ ] Works on tablet (768x1024)
-- [ ] Works on mobile (375x667)
-- [ ] Print view displays correctly
-
-## API Requirements
-
-The pedigree tree depends on these existing API endpoints:
-
-### Required Endpoints
-
-1. **GET `/api/pedigree/:id`** - Get pedigree tree
-   - Must return nested sire/dam objects
-   - Should include: id, name, sex, registration_number, birth_date
-   - Example response:
-   ```json
-   {
-     "id": 1,
-     "name": "Dog Name",
-     "sex": "male",
-     "registration_number": "ABC123",
-     "birth_date": "2020-01-01",
-     "sire": {
-       "id": 2,
-       "name": "Father Name",
-       "sex": "male",
-       "sire": { ... },
-       "dam": { ... }
-     },
-     "dam": {
-       "id": 3,
-       "name": "Mother Name",
-       "sex": "female",
-       "sire": { ... },
-       "dam": { ... }
-     }
-   }
-   ```
-
-2. **GET `/api/pedigree/:id/coi`** - Get COI calculation
-   - Returns coefficient of inbreeding
-   - Example response:
-   ```json
-   {
-     "coi": 3.125,
-     "generations": 5
-   }
-   ```
-
-## Known Limitations
-
-1. **Performance**: Very large pedigrees (>100 nodes) may experience slowdown
-2. **COI**: Calculation requires complete pedigree data
-3. **Mobile**: Tree may be difficult to navigate on very small screens
-4. **Print**: May require landscape orientation for best results
-
-## Future Enhancements (Not in Sprint 1)
-
-- [ ] PDF export functionality
-- [ ] Highlight common ancestors between two dogs
-- [ ] Show inbreeding loops visually
-- [ ] Ancestor search/filter
-- [ ] Save custom tree views
-- [ ] Share pedigree links
-- [ ] Printable certificate template
-
-## Troubleshooting
-
-### Tree Doesn't Display
-- Check browser console for errors
-- Verify API endpoint `/api/pedigree/:id` is working
-- Check that dog has parent data in database
-- Ensure dependencies are installed (`npm install`)
-
-### Zoom/Pan Not Working
-- Check that react-d3-tree is properly installed
-- Clear browser cache and reload
-- Try in different browser
-
-### COI Not Showing
-- Verify `/api/pedigree/:id/coi` endpoint exists
-- Check that pedigree has sufficient data (at least 3 generations)
-- COI may be null for incomplete pedigrees
-
-### Styling Issues
-- Ensure `PedigreeTree.css` is imported in component
-- Check that CSS variables are defined in main stylesheet
-- Clear browser cache
-
