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

+# 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.

+# Full SDD workflow
+
+## Configuration
+- **Artifacts Path**: {@artifacts_path} → `.zenflow/tasks/{task_id}`
+
+---
+
+## 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.

+- **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.
+
+Rule of thumb for step size: each step = a coherent unit of work (component, endpoint, test suite). Not too granular (single function), not too broad (entire feature). Unit tests are part of each step, not separate.
+
+Update `{@artifacts_path}/plan.md`.

-# 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.

+# DEVELOPMENT.md
+
+This document provides technical details and guidelines for developing and maintaining the BREEDR Genealogy Management System.
+
+## Tech Stack Overview
+
+### Backend
+- **Node.js & Express**: Core API server.
+- **better-sqlite3**: High-performance SQLite driver.
+- **Multer**: Multi-part form data handling for photo uploads.
+- **Bcrypt & JWT**: (Planned) Authentication and security.
+
+### Frontend
+- **React 18 & Vite**: Modern reactive UI with fast HMR.
+- **React Router 6**: Client-side navigation.
+- **Lucide React**: Consistent iconography.
+- **React-D3-Tree & D3.js**: Dynamic pedigree visualization.
+- **Axios**: Promised-based HTTP client for API communication.
+
+---
+
+## Database Architecture
+
+### SQLite Implementation
+The database is a single file located at `data/breedr.db`. This directory is automatically created on startup.
+
+### "Parents Table" Approach
+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'.
+
+**Benefits**: Supports recursive lookups, avoids `ALTER TABLE` complexity for lineage changes, and allows historical mapping of ancestors without full profiles.
+
+### Safe Migrations
+BREEDR use a migration-free synchronization approach:
+1. `server/db/init.js` defines the latest table structures.
+2. Safe `ALTER TABLE` guards inject missing columns on startup.
+3. This ensures data persistence across updates without manual migration scripts.
+
+### Key Tables
+- `dogs`: Registry for kennel and external dogs.
+- `parents`: Ancestry relationships.
+- `litters`: Produced breeding groups.
+- `health_records`: OFA clearances and vet records.
+- `genetic_tests`: DNA panel results.
+- `settings`: Kennel-wide configuration (single row).
+

+├── App.jsx         # Routing & Layout
+└── index.css       # Global styles & Design System
+```
+
+### 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`).

+### 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.

-## 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

-## Upgrading
-
-### From Earlier Versions
-
-If you have an **old database with sire/dam columns** or missing litter_id:
-
-```bash
-# Backup your data
-cp data/breedr.db data/breedr.db.backup
-
-# Delete old database
-rm data/breedr.db
-
-# Pull latest code
-git pull
-
-# Restart (will create clean schema)
-docker-compose restart
-```
-
-**Important:** The new schema uses a `parents` table instead of sire/dam columns. Parent data cannot be automatically migrated - you'll need to re-enter parent relationships.
-
-## Troubleshooting
-
-### "no such column: weight" or "no such column: sire_id"
-
-Your database has an old schema. Delete and recreate:
-
-```bash
-rm data/breedr.db
-docker-compose restart
-```
-
-### Parent relationships not saving
-
-Check server logs for:
-```
-✔ Dog inserted with ID: 123
-  Adding sire relationship: dog 123 -> sire 5
-  ✔ Sire relationship added
-```
-
-If you don't see these logs, ensure `sire_id` and `dam_id` are being sent in the API request.
-
-### 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.
-

-# 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

-
-## 🚀 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

-- 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

-## 🧐 Developer Notes
-
-### New Development Workflow
-
-**For database changes:**
-1. Edit `server/db/init.js` only
-2. Test with fresh database: `rm data/breedr.db && npm run dev`
-3. Update `DATABASE.md` documentation
-4. No migrations needed!
-
-**For API changes involving parents:**
-- Use `parents` table for sire/dam relationships
-- Check `server/routes/dogs.js` for examples
-- Log relationship creation for debugging
-
-### Testing
-
-Test these scenarios:
-1. Fresh install - database created correctly
-2. Add dog with sire/dam - parents table populated
-3. Add dog via litter - litter_id set, parents auto-linked
-4. View dog details - parents and offspring shown correctly
-5. Pedigree view - multi-generation tree displays
-

-## 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
