Add .gitea/workflows/docker-build.yml

All list endpoints now accept ?page and ?limit (default 50, max 200) and
return { data, total, page, limit } instead of a bare array, preventing
memory and performance failures at scale.

- GET /api/dogs: adds pagination, server-side search (?search) and sex
  filter (?sex), and a stats aggregate (total/males/females) for the
  Dashboard to avoid counting from the array
- GET /api/litters: adds pagination; also fixes N+1 query by fetching
  all puppies for the current page in a single query instead of one per
  litter
- DogList: moves search/sex filtering server-side with 300ms debounce;
  adds Prev/Next pagination controls
- LitterList: uses paginated response; adds Prev/Next pagination controls
- Dashboard: reads counts from stats/total fields instead of array length
- LitterDetail, LitterForm: switch dogs fetch to /api/dogs/all (complete
  list, no pagination, for sire/dam dropdowns)
- DogForm: updates litters fetch to use paginated response shape

-# 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.

-## 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
+### SQLite Implementation
-The database is a single SQLite file located at `data/breedr.db`. This directory is automatically created on startup if it doesn't exist.
+The database is a single file located at `data/breedr.db`. This directory is automatically created on startup.
-
-### 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:
+Parent relationships are managed in a dedicated `parents` table rather than columns in the `dogs` table.
+- ** dog_id**: The child dog.
+- ** parent_id**: The parent dog.
+- ** parent_type**: 'sire' or 'dam'.
 
-```sql
+**Benefits**: Supports recursive lookups, avoids `ALTER TABLE` complexity for lineage changes, and allows historical mapping of ancestors without full profiles.
-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**:
+### Safe Migrations
-- Avoids complex `ALTER TABLE` operations when changing pedigree logic.
+BREEDR use a migration-free synchronization approach:
-- Cleanly separates dog attributes from lineage relationships.
+1. `server/db/init.js` defines the latest table structures.
-- Supports indexing for fast recursive pedigree lookups.
+2. Safe `ALTER TABLE` guards inject missing columns on startup.
+3. This ensures data persistence across updates without manual migration scripts.
 
 ### Key Tables
-- **`dogs`**: Core dog data (name, breed, sex, microchip, etc.).
+- `dogs`: Registry for kennel and external dogs.
-- **`parents`**: Lineage relationships (Sire/Dam).
+- `parents`: Ancestry relationships.
-- **`litters`**: Groups of dogs from a single breeding.
+- `litters`: Produced breeding groups.
-- **`breeding_records`**: Planned or completed breeding events.
+- `health_records`: OFA clearances and vet records.
-- **`health_records`**: OFA results, vaccinations, and other health tests.
+- `genetic_tests`: DNA panel results.
-- **`genetic_tests`**: DNA panel results.
+- `settings`: Kennel-wide configuration (single row).
-- **`settings`**: Kennel-wide configurations.
 
-## Backend Development

-### API Routes
+## Frontend Documentation
-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
+### Project Structure
-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
+### Design System & Styling
+The UI follows a modern dark-theme aesthetic using **CSS Variables** defined in `index.css`:
+- `--primary`: Brand color (Warm Amber/Blue).
+- `--bg-primary`: Deep Slate background.
+- Glassmorphism effects via `backdrop-filter`.
+- Responsive grid layouts (`.grid-2`, `.grid-3`).
 
-### State Management
+### Key Components
-- **Settings**: Managed globally via `SettingsProvider` in `client/src/hooks/useSettings.jsx`.
+- **PedigreeTree**: horizontal, D3-powered tree with zoom/pan.
-- **Component State**: Local `useState` and `useEffect` are preferred for feature-specific data.
+- **DogForm**: Dual-mode (Kennel/External) dog entry with parent selection.
 
-### Styling
+---
-- CSS Variables are used for theming.
-- The UI uses a modern, clean design with Lucide icons.
 
-### Pedigree Trees
+## API & Backend Development
-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
+### Route Modules (`server/routes/`)
+- `/api/dogs`: Dog registry and photo uploads.
+- `/api/litters`: Litter management and puppy linking.
+- `/api/pedigree`: Recursive ancestry/descendant tree generation.
+- `/api/breeding`: Heat cycle tracking and whelping projections.
 
+### Environment Variables

-```
-
-## 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
-

-## Common Workflows
-
-### Workflow 1: Breeding a Litter
-
-1. ✓ Select breeding pair (sire and dam)
-2. ✓ Create litter record with breeding date
-3. ✓ Track whelping date when puppies are born
-4. ✓ Add each puppy:
-   - Link to the litter
-   - Enter individual details
-   - Assign registration numbers
-5. ✓ View pedigree of any puppy to see full ancestry
-
-### Workflow 2: Recording Historical Dogs
-
-1. ✓ Add foundation dogs (no parents)
-2. ✓ Add their offspring using manual parent selection
-3. ✓ Continue building the family tree
-4. ✓ View pedigrees to verify relationships
-
-### Workflow 3: Planning a Breeding
-
-1. ✓ View pedigrees of potential sire and dam
-2. ✓ Check for common ancestors
-3. ✓ Use trial pairing tool (coming soon)
-4. ✓ Create litter when breeding occurs
-
----
-
-## Tips & Best Practices
-
-### For Litter Management
-
-✅ **Do:**
-- Create the litter record BEFORE adding puppies
-- Enter accurate breeding dates for record keeping
-- Use meaningful notes (progesterone timing, heat cycle info)
-- Link puppies to litters for automatic parent relationships
-
-❌ **Don't:**
-- Don't change sire/dam after litter creation (create new litter instead)
-- Don't forget to update whelping date when puppies arrive
-- Avoid mixing litter-linked and manually-parented puppies
-
-### For Pedigree Viewing
-
-✅ **Do:**
-- Zoom out to see the full tree at once
-- Use drag to focus on specific branches
-- Click nodes to see additional details
-- Reset view if you get lost
-
-❌ **Don't:**
-- Don't try to edit from pedigree view (use dog edit form)
-- Avoid excessive zooming (can make nodes too small)
-
-### Data Entry Tips
-
-1. **Registration Numbers**: Enter consistently (e.g., "AKC-12345")
-2. **Microchips**: Use full 15-digit number
-3. **Birth Dates**: Critical for age calculations and sorting
-4. **Breed Names**: Keep consistent spelling and capitalization
-5. **Colors**: Use standard color terminology for your breed
-

-
-## Troubleshooting
-
-### "No such column: sire" Error
-
-**Problem:** Getting this error when adding a dog
-
-**Solution:** 
-1. Make sure you ran the migration:
-   ```bash
-   node server/db/migrate_litter_id.js
-   ```
-2. Restart the server
-3. Try again
-
-### Pedigree Tree Not Loading
-
-**Problem:** Pedigree modal shows "Loading..." forever
-
-**Possible Causes:**
-- Dog has no parents recorded
-- Network issue
-- Server not running
-
-**Solution:**
-1. Check browser console for errors
-2. Verify server is running
-3. Ensure dog has at least one parent recorded
-
-### Parents Not Auto-Populating
-
-**Problem:** Selected a litter but parents didn't fill in
-
-**Solution:**
-1. Refresh the page
-2. Make sure litter has valid sire and dam
-3. Try selecting the litter again
-
-### Can't See All Generations
-
-**Problem:** Pedigree tree only shows 2-3 generations
-
-**This is normal if:**
-- Older generations don't have parents recorded
-- Foundation dogs have no ancestry
-- You need to add more historical data

-### Recently Added (March 10, 2026 — v0.6.1)
+## 🚀 Quick Start
-- **✅ 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)
-
-### 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
-

-
-## Quick Start
-
-### Docker Deployment (Recommended)
 
+### 1. Docker Deployment (Recommended)
 ```bash
-# Clone repository
 git clone https://git.alwisp.com/jason/breedr.git
 cd breedr
-
-# Build Docker image
-docker build -t breedr:latest .
-
-# Run with docker-compose
-docker-compose up -d
-```
-
-Access at: `http://localhost:3000`
-
-### Upgrading an Existing Installation
-
-The database now uses safe `ALTER TABLE` guards — **you do not need to delete your database to upgrade**. Just pull and rebuild:
-
-```bash
-docker-compose down
-git pull origin master
 docker-compose up -d --build
 ```
+Access at: `http://localhost:3000`
 
-New columns (`is_champion`, all `settings` kennel fields) are added automatically on first boot. Your existing dog data is preserved.
+### 2. Manual Development Setup
-
-### 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)
-
-## Environment Variables
-
-- `NODE_ENV` - production/development (default: production)
-- `PORT` - Server port (default: 3000)
-- `DATA_DIR` - Data directory for SQLite file (default: /app/data)
-- `UPLOAD_PATH` - Upload directory (default: /app/uploads)
-- `STATIC_PATH` - Static assets directory (default: /app/static)
-
-## Development
-
-### Local Development Setup
-
 ```bash
-# Install dependencies
 npm install
-
-# Run development server (frontend + backend, nodemon auto-reload)
 npm run dev
-
-# Build for production
-npm run build
 ```
+> **Note:** The database initializes automatically on first boot. No manual migrations are required.
 
-> **Note:** `npm run dev` uses nodemon for auto-reload on the server. `npm start` (production) does **not** watch for changes — restart is required after pulling updates.
+---

-## 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
-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 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

-- **Added:** Full kennel settings columns in `settings` table with migration guards
-- **Added:** `SettingsProvider` / `useSettings` React context for kennel name in navbar
-- **Fixed:** `useSettings.js` → `useSettings.jsx` (Vite build failure — JSX in `.js` file)
-- **Fixed:** `server/index.js` — `initDatabase()` called with no args; removed duplicate `/api/health` route
-- **Fixed:** `server/routes/settings.js` — rewrote from double-encoded base64 + old key/value schema
-- **Fixed:** `DB_PATH` arg removed from `initDatabase()` call; `DATA_DIR` env var now controls directory

-# 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

-
-## 🚀 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
-
----
-

-## 📋 Phase 4b: Health & Genetics (NEXT UP − v0.7.0)
 
+### 🔜 Next Up — Phase 4b: Health & Genetics Build Order
 > **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
-

-## Microchip Field Fix Verification
-
-### ✅ Schema Files (All Correct)
-
-#### 1. Database Schema: `server/db/init.js`
-- [x] **Line 29:** `microchip TEXT,` (no UNIQUE constraint)
-- [x] **Lines 38-43:** Partial unique index created
-  ```sql
-  CREATE UNIQUE INDEX IF NOT EXISTS idx_dogs_microchip 
-  ON dogs(microchip) 
-  WHERE microchip IS NOT NULL
-  ```
-
-**Status:** ✅ Correct for future installations
-
----
-
-#### 2. UI Form: `client/src/components/DogForm.jsx`
-- [x] **Line 150:** Microchip input has NO `required` attribute
-- [x] Label shows "Microchip Number" (no asterisk)
-- [x] Field is truly optional in the UI
-
-**Status:** ✅ Correct - users can leave microchip blank
-
----
-
-#### 3. Migration Script: `server/db/migrate_microchip.js`
-- [x] Exists and is executable
-- [x] Safely migrates existing databases
-- [x] Idempotent (can run multiple times)
-- [x] Preserves all data during migration
-
-**Status:** ✅ Available for existing installations
-
----
-
-#### 4. Migration Helper: `migrate-now.sh`
-- [x] Shell script for easy execution
-- [x] Checks if container is running
-- [x] Runs migration inside container
-- [x] Restarts container after migration
-
-**Status:** ✅ User-friendly migration tool
-
----
-
-#### 5. Documentation: `docs/MICROCHIP_FIX.md`
-- [x] Problem explanation
-- [x] Solution details
-- [x] Migration instructions (3 options)
-- [x] Verification tests
-- [x] Troubleshooting guide
-
-**Status:** ✅ Complete documentation
-
----
-
-#### 6. README: `README.md`
-- [x] Migration notice at top
-- [x] Link to detailed documentation
-- [x] Upgrade instructions included
-- [x] Recent updates section added
-
-**Status:** ✅ Users will see migration notice
-
----
-
-## For Future Installations
-
-### Fresh Install (No Migration Needed)
-
-When a user does a **fresh install** (no existing database):
-
-1. Container starts
-2. `server/db/init.js` runs automatically
-3. Database created with **correct schema**
-4. Microchip field is **optional from the start**
-5. No migration required ✅
-
-### Existing Installation (Migration Required)
-
-When a user **upgrades** from an old version:
-
-1. Pull latest code
-2. Rebuild Docker image
-3. Start container
-4. **Must run migration:** `docker exec -it breedr node server/db/migrate_microchip.js`
-5. Restart container
-6. Microchip field now optional ✅
-
----
-
-## Testing Checklist
-
-### Test 1: Add Dog Without Microchip
-```bash
-curl -X POST http://localhost:3000/api/dogs \
-  -H "Content-Type: application/json" \
-  -d '{"name":"TestDog1","breed":"Lab","sex":"male"}'
-```
-**Expected:** ✅ Success (201 Created)
-
-### Test 2: Add Multiple Dogs Without Microchips
-```bash
-curl -X POST http://localhost:3000/api/dogs \
-  -H "Content-Type: application/json" \
-  -d '{"name":"TestDog2","breed":"Lab","sex":"female"}'
-```
-**Expected:** ✅ Success (multiple NULL values allowed)
-
-### Test 3: Add Dog With Microchip
-```bash
-curl -X POST http://localhost:3000/api/dogs \
-  -H "Content-Type: application/json" \
-  -d '{"name":"TestDog3","breed":"Lab","sex":"male","microchip":"123456789"}'
-```
-**Expected:** ✅ Success
-
-### Test 4: Duplicate Microchip Should Fail
-```bash
-curl -X POST http://localhost:3000/api/dogs \
-  -H "Content-Type: application/json" \
-  -d '{"name":"TestDog4","breed":"Lab","sex":"female","microchip":"123456789"}'
-```
-**Expected:** ❌ Error (UNIQUE constraint still enforced for non-NULL)
-
----
-
-## Database Verification
-
-### Check Schema Directly
-
-```bash
-# Enter container
-docker exec -it breedr sh
-
-# Open SQLite CLI
-sqlite3 /app/data/breedr.db
-
-# Check table schema
-.schema dogs
-
-# Should show:
-# microchip TEXT,  (no UNIQUE)
-
-# Check indexes
-.indexes dogs
-
-# Should show:
-# idx_dogs_microchip (partial index)
-
-# Verify partial index
-SELECT sql FROM sqlite_master 
-WHERE type='index' AND name='idx_dogs_microchip';
-
-# Should show:
-# CREATE UNIQUE INDEX idx_dogs_microchip 
-# ON dogs(microchip) WHERE microchip IS NOT NULL
-```
-
----
-
-## Rollback Plan
-
-If something goes wrong:
-
-### Option A: Restore Backup
-```bash
-docker stop breedr
-cp /mnt/user/appdata/breedr/breedr.db.backup \
-   /mnt/user/appdata/breedr/breedr.db
-docker start breedr
-```
-
-### Option B: Re-run Migration
-```bash
-docker exec -it breedr node server/db/migrate_microchip.js
-docker restart breedr
-```
-
-### Option C: Fresh Database (Data Loss)
-```bash
-docker stop breedr
-rm /mnt/user/appdata/breedr/breedr.db
-docker start breedr
-```
-
----
-
-## Deployment Verification
-
-After deploying to production:
-
-- [ ] Check container logs for schema initialization
-- [ ] Verify database schema with SQLite CLI
-- [ ] Test adding dog without microchip via UI
-- [ ] Test adding dog with microchip via UI
-- [ ] Confirm no UNIQUE constraint errors
-- [ ] Verify partial index exists
-- [ ] Test duplicate microchip still fails
-
----
-
-## Common Issues
-
-### Issue: Still Getting UNIQUE Constraint Error
-
-**Cause:** Migration not run on existing database
-
-**Solution:**
-```bash
-docker exec -it breedr node server/db/migrate_microchip.js
-docker restart breedr
-```
-
-### Issue: Migration Script Not Found
-
-**Cause:** Old code still in container
-
-**Solution:**
-```bash
-cd /mnt/user/appdata/breedr-build
-git pull
-docker build -t breedr:latest .
-docker stop breedr && docker rm breedr
-# Recreate container with new image
-```
-
-### Issue: Microchip Required in UI
-
-**Cause:** Browser cached old JavaScript
-
-**Solution:**
-- Hard refresh: Ctrl+Shift+R (Windows/Linux) or Cmd+Shift+R (Mac)
-- Clear browser cache
-- Try incognito/private window
-
----
-
-## File Manifest
-
-### Core Files (Must Be Present)
-- ✅ `server/db/init.js` - Database schema (corrected)
-- ✅ `server/db/migrate_microchip.js` - Migration script
-- ✅ `client/src/components/DogForm.jsx` - UI form (microchip optional)
-- ✅ `migrate-now.sh` - Helper script
-- ✅ `docs/MICROCHIP_FIX.md` - Detailed documentation
-- ✅ `docs/VERIFICATION_CHECKLIST.md` - This file
-- ✅ `README.md` - Updated with migration notice
-
-### Validation Commands
-
-```bash
-# Check all files exist
-ls -la server/db/init.js
-ls -la server/db/migrate_microchip.js
-ls -la client/src/components/DogForm.jsx
-ls -la migrate-now.sh
-ls -la docs/MICROCHIP_FIX.md
-ls -la docs/VERIFICATION_CHECKLIST.md
-
-# Verify microchip field in init.js
-grep -n "microchip TEXT" server/db/init.js
-# Should show line 29 with NO UNIQUE
-
-# Verify partial index
-grep -A2 "idx_dogs_microchip" server/db/init.js
-# Should show WHERE clause
-
-# Verify form has no required
-grep -n 'name="microchip"' client/src/components/DogForm.jsx
-# Should NOT have required attribute
-```
-
