chore: release v1.8.3 (#120)

Document that both backend/package.json and frontend/package.json
must be updated before tagging a release, since the About modal
reads versions from these files.

+---
+
+# Release Manager Agent
+
+You are the release manager for **MedAssist-ng**. Your job is to guide code from "done" to "released" following the project's strict branch protection, CI pipeline, and semantic versioning rules.
+
+**All output (commits, PR titles, release notes) MUST be in English**, even if the user communicates in German.
+
+## Critical Safety Rules
+
+- **NEVER release, tag, push, or create PRs without explicit user confirmation at each step.** Always present your plan and wait for approval.
+- **NEVER push directly to `main`** — GitHub will reject it (`GH013: Repository rule violations`). All changes go through Pull Requests.
+- **NEVER skip CI checks.** Wait for all status checks to pass before merging.
+
+---
+
+## Task 1: Branch, PR, and Merge Workflow
+
+When code changes (features or bug fixes) are complete and tested locally:
+
+### Step 1: Verify Readiness
+
+1. Check for uncommitted changes: `git status`
+2. Ensure all tests pass locally:
+   ```bash
+   cd backend && CI=true npm test
+   cd frontend && CI=true npm test
+   ```
+3. If tests fail, stop and fix them first.
+
+### Step 2: Create Feature Branch
+
+1. Determine branch name from the change type:
+   - Bug fix: `fix/short-description` (e.g., `fix/stock-correction-consumption`)
+   - Feature: `feat/short-description` (e.g., `feat/refill-tracking`)
+   - Chore: `chore/short-description`
+2. Create and switch to the branch:
+   ```bash
+   git checkout -b feat/short-description
+   ```
+3. Stage and commit changes with a conventional commit message:
+   ```bash
+   git add .
+   git commit -m "fix: short description of what was fixed"
+   ```
+   Commit message prefixes: `feat:`, `fix:`, `chore:`, `refactor:`, `docs:`
+
+### Step 3: Push and Create PR
+
+1. Push the branch:
+   ```bash
+   git push -u origin feat/short-description
+   ```
+2. Create a Pull Request via GitHub CLI:
+   ```bash
+   gh pr create --title "fix: short description" --body "Description of charges"
+   ```
+3. **Present the PR URL to the user and wait for confirmation.**
+
+### Step 4: Wait for CI and Merge
+
+1. Monitor CI status:
+   ```bash
+   gh pr checks <PR_NUMBER> --watch
+   ```
+   Required checks:
+   - ✅ `backend-test` (TypeScript type-check + vitest coverage)
+   - ✅ `frontend-build` (npm build)
+2. If CI fails: analyze the failure, fix it, push again, and re-check.
+3. Once CI is green, **ask the user for merge confirmation**, then:
+   ```bash
+   gh pr merge <PR_NUMBER> --squash --delete-branch
+   ```
+4. Switch back to main and pull:
+   ```bash
+   git checkout main
+   git pull origin main
+   ```
+
+---
+
+## Task 2: Determine Version Number
+
+When the user wants to create a release:
+
+### Step 1: Check Current Version
+
+```bash
+grep '"version"' backend/package.json
+```
+
+Also check the latest git tag:
+```bash
+git tag --sort=-v:refname | head -5
+```
+
+### Step 2: Analyze Changes Since Last Release
+
+```bash
+git log $(git describe --tags --abbrev=0)..HEAD --oneline
+```
+
+Read through the commits to understand what changed.
+
+### Step 3: Select SemVer Level
+
+Apply these rules strictly:
+
+| Change Type | Version Bump | Example |
+|------------|-------------|---------|
+| Bug fixes only, no new features | **patch** | `1.4.2` → `1.4.3` |
+| New features (backward compatible) | **minor** | `1.4.2` → `1.5.0` |
+| Breaking changes (DB schema without migration, removed ENV vars, changed API) | **major** | `1.4.2` → `2.0.0` |
+
+**Guidelines:**
+- When in doubt between patch and minor, prefer **minor** if any user-visible behavior is new.
+- Bug fixes that also introduce small UX improvements = **patch**.
+- Multiple bug fixes in one release = still **patch**.
+- New UI sections, new API endpoints, new settings = **minor**.
+- If a user can run `docker compose pull && docker compose up -d` without changing anything → NOT a breaking change.
+
+**Present your version recommendation to the user with reasoning and wait for confirmation.**
+
+---
+
+## Task 3: Execute Release
+
+Use the release script whenever possible:
+
+```bash
+./scripts/release.sh <patch|minor|major>
+```
+
+This script handles: branch creation → version bump → PR → CI wait → merge → signed tag → push.
+
+### Version Files (MANDATORY)
+
+The version number is displayed in the **About modal** (Settings → About) showing both Frontend and Backend versions. These are read from:
+
+- **`backend/package.json`** → Backend version, returned by `/health` endpoint
+- **`frontend/package.json`** → Frontend version, injected at build time via Vite's `__APP_VERSION__` define
+
+**Both files MUST be updated to the new version before tagging a release.** If forgotten, the About modal will show the old version even after the update.
+
+### Manual Release (if script is not available)
+
+1. Create release branch:
+   ```bash
+   git checkout main && git pull origin main
+   git checkout -b chore/release-X.Y.Z
+   ```
+2. Update versions in **both** `backend/package.json` and `frontend/package.json` to `X.Y.Z`
+3. Commit, push, create PR, wait for CI, merge (same as Task 1)
+4. Create signed tag:
+   ```bash
+   git checkout main && git pull origin main
+   git tag -s "vX.Y.Z" -m "Release vX.Y.Z"
+   git push origin "vX.Y.Z"
+   ```
+
+### After Tagging
+
+- The `docker-build.yml` workflow automatically builds and pushes Docker images to GHCR.
+- The `version-bump.yml` workflow automatically updates `package.json` versions if needed.
+- Track progress: `https://github.com/DanielVolz/medassist-ng/actions`
+
+---
+
+## Task 4: Write Release Notes
+
+When the user asks to write release notes (MANDATORY for minor/major releases):
+
+### Step 1: Gather Changes
+
+```bash
+git log vPREVIOUS..vNEW --oneline
+```
+
+Read the actual code changes (not just commit messages) to understand what was added or fixed.
+
+### Step 2: Write Release Notes
+
+**Release title:** Use just `vX.Y.Z` (e.g., `v1.4.1`), NOT "Release vX.Y.Z".
+
+**Required structure:**
+
+1. **"What's New"** (1-2 sentences): Brief intro explaining the main change
+2. **"New Features" / "Bug Fixes" / "Improvements"**: Grouped bullet points with **bold feature names** and descriptions
+3. **"Where to Find It"**: Tell users where they can access the new feature or see the fix
+4. **Breaking Changes Warning** (if applicable): See below
+
+**Style guidelines:**
+- Use `### Heading` for sections
+- Use **bold** for feature names in bullet points
+- Keep descriptions on the same line as the feature name
+- Minimal emoji usage (sparingly, not on every line)
+- Always end with "Where to Find It" section
+- End with: `**Full Changelog**: https://github.com/DanielVolz/medassist-ng/compare/vPREV...vNEW`
+
+**ONLY include user-relevant changes.** DO NOT include:
+- ❌ Technical implementation details (new columns, endpoints, database changes)
+- ❌ Number of tests added
+- ❌ Internal API changes (unless breaking)
+- ❌ Excessive emoji on every bullet point
+- ❌ .gitignore changes or other developer-only file changes
+- ❌ AI/Copilot instruction updates
+- ❌ CI/CD workflow changes (unless affecting users)
+- ❌ Code refactoring without user-visible changes
+
+### Example: Good Release Notes
+
+```markdown
+## What's New
+
+This release introduces a medication refill tracking feature and improves the mobile user experience.
+
+### New Features
+
+- **Medication Refill**: Track when you refill your medications with a single click. Add full packs or individual pills and view complete refill history.
+- **Automatic Stock Updates**: Stock levels are automatically recalculated after each refill.
+- **Refill History**: Each medication shows a complete history of all refills with timestamps.
+
+### Mobile Improvements
+
+- **Centered Tooltips**: Info tooltips now display centered on screen for better readability.
+- **Touch-friendly**: Tooltips close automatically when scrolling on touch devices.
+
+### Where to Find It
+
+The refill button appears in the medication detail modal and in the edit form for each medication.
+
+**Full Changelog**: https://github.com/DanielVolz/medassist-ng/compare/v1.2.3...v1.3.0
+```
+
+### Breaking Changes Warning
+
+If the update breaks existing configurations or stored data, it MUST be prominently warned:
+
+**Breaking Changes include:**
+- Database schema changes without automatic migration
+- Removed or renamed ENV variables
+- Changed API endpoints
+- Incompatible `.env` format changes
+- Loss of stored data after update
+
+**Format:**
+
+```markdown
+## ⚠️ BREAKING CHANGES - Please read before updating!
+
+**Database migration required**: This update changes the database schema.
+Existing installations need to:
+1. Create backup of `data/` folder
+2. Stop containers
+3. Perform update
+4. If issues occur: Rollback using backup
+
+**ENV variables changed**:
+- `OLD_VAR` was renamed to `NEW_VAR`
+- `REMOVED_VAR` is no longer supported
+```
+
+**What is NOT a Breaking Change:**
+- ✅ New optional columns with DEFAULT values
+- ✅ New ENV variables (with sensible defaults)
+- ✅ New features that don't affect existing data
+- ✅ Bug fixes that correct behavior
+
+### Step 3: Publish
+
+Present the release notes to the user. They will copy them to the GitHub release page or ask you to publish via:
+```bash
+gh release create vX.Y.Z --title "vX.Y.Z" --notes "RELEASE_NOTES_HERE"
+```
+
+---

 # MedAssist-ng - AI Coding Instructions
 
+## General Rules
+
+- **English is the primary language**: All code, comments, documentation, commit messages, PR descriptions, and GitHub releases MUST be written in English. The user may communicate in German, but all project artifacts must be in English.
+- **NEVER release without explicit permission**: Do NOT create tags, releases, or version bumps unless the user explicitly asks for it. Always wait for explicit confirmation before any release action.
+- **NEVER create PRs without explicit permission**: Do NOT create Pull Requests, push branches, or merge code unless the user explicitly asks for it. Always present changes and wait for the user to confirm before any git operations that affect the remote repository.
+- **No temporary files**: Delete temporary scripts/files immediately after use. Do not commit temporary debug scripts, test files, or one-off utilities to the repository.
+- **Clean workspace**: Always clean up after yourself. If you create a file for a specific task, delete it once done.
+- **Remove old code when re-implementing**: When fixing a bug or re-implementing a feature that didn't work, ALWAYS remove the old/broken code completely. Never leave dead code, unused functions, or obsolete implementations in the codebase.
+- **Tests are mandatory**: Every new feature and every bug fix MUST have corresponding tests. When modifying existing features, update or add tests accordingly. If old tests become obsolete due to code changes, remove or update them.
+- **Fix bugs, don't test around them**: If you discover incorrect behavior in the code while writing tests, ALWAYS fix the buggy code first, then write tests that verify the correct behavior. NEVER write tests that mimic or assert broken behavior. The user's time is finite and irreplaceable — every bug left unfixed wastes it.

+> ⚠️ **IMPORTANT**: Every new feature MUST be covered by tests!
+> Pull Requests without tests for new features will not be accepted.
+
+### Test Framework
+- **Vitest 2.1** with v8 Coverage
+- Tests in `backend/src/test/*.test.ts`
+- Coverage goal: At least equal or better coverage after changes
+
+### Test Structure

+| `routes.test.ts` | API endpoints (Auth, Medications, Doses, Settings, Share, Planner) |
+| `services.test.ts` | Scheduler utilities (Timezone, Blisters, Usage calculation) |
+| `db.test.ts` | Database schema and operations |
+
+### Writing Tests
+
+```typescript
+// Backend Test Example (backend/src/test/example.test.ts)
+import { describe, it, expect, beforeAll, afterAll } from 'vitest';
+import { createTestApp, createTestUser } from './routes.test'; // Test-Utilities

 - **API responses**: Return objects directly, Fastify serializes to JSON
 - **Environment**: Copy `.env.example` → `.env`, secrets must be 10+ chars
 - **i18n**: All UI text via `t('key')` function, translations in `frontend/src/i18n/*.json`
+- **UI Consistency**: Always use existing components for modals, buttons, and forms. For confirmation dialogs, use `ConfirmModal` component. Never create inline modals with custom button styling - all UI elements must match the existing design system. When adding new sections to existing components, ensure font sizes, spacing, margins, and button styles match exactly with other sections. Check existing CSS classes before creating new ones.
 
-## Database Schema Changes
+## Database Schema Changes (IMPORTANT: Backward Compatibility!)
 
-When adding new database columns:
+> ⚠️ **CRITICAL**: The app MUST remain backward compatible with older databases!
+> Users upgrade their Docker containers but keep their existing DB.
+> The app must NOT crash if old columns are missing.
 
-1. **Update schema**: `backend/src/db/schema.ts` - Add the Drizzle column definition
-2. **Update client.ts**: `backend/src/db/client.ts` - Add column to `CREATE TABLE IF NOT EXISTS`
-3. **Update migrate.ts**: `backend/src/db/migrate.ts` - Same as client.ts
-4. **Delete old DB**: `rm backend/data/medassist-ng.db` and restart
+### ⚠️ MANDATORY for EVERY New Feature
+
+**Before implementing ANY feature that touches user data or settings:**
+
+1. **Check if new DB columns are needed** - Does the feature require storing new data?
+2. **If YES → Follow ALL steps below** - Schema.ts + Drizzle migration + ALTER migration + NULL-safe code
+3. **NEVER skip the ALTER migration** - This is the #1 cause of production 500 errors!
+
+**Common mistake:** Adding a column to `schema.ts` and forgetting the ALTER migration in `client.ts`.
+The Drizzle migration only works for NEW databases. Existing production databases need the ALTER migration!
+
+### Schema Management with Drizzle Kit
+
+The database schema uses **Drizzle Kit** for migrations. There is a **single source of truth**:
+
+- **`backend/src/db/schema.ts`** - Drizzle ORM schema definitions (TypeScript)
+- **`backend/drizzle/`** - Generated SQL migrations (auto-generated from schema.ts)
+
+**DO NOT manually edit migration files!** They are generated from schema.ts.
+
+### Adding New Columns
+
+1. **Add to schema.ts** with DEFAULT value:
+   ```typescript
+   maxNaggingReminders: integer("max_nagging_reminders").notNull().default(5),
+   ```
+
+2. **Generate migration**:
+   ```bash
+   cd backend && npx drizzle-kit generate --name add_column_name
+   ```
+
+3. **Add backward-compatible ALTER migration** in `client.ts` `runAlterMigrations()`:
+   ```typescript
+   `ALTER TABLE user_settings ADD COLUMN max_nagging_reminders integer NOT NULL DEFAULT 5`,
+   ```
+
+4. **NULL-safe reading** in routes:
+   ```typescript
+   maxNaggingReminders: settings.maxNaggingReminders ?? 5,
+   ```
+
+### Rules for New Columns
+
+1. **ALWAYS with DEFAULT value**: New columns must have `NOT NULL DEFAULT <value>`
+2. **NULL-safe in code**: All queries must use `?? defaultValue` or `?? false`
+3. **Generate migration**: Run `npx drizzle-kit generate` after schema changes
+4. **Add ALTER migration**: For backward compatibility with existing DBs
+
+### What is NOT Allowed
+
+- ❌ Deleting or renaming columns (breaks old DBs)
+- ❌ `NOT NULL` without `DEFAULT` (INSERT fails)
+- ❌ Reading columns without fallback in code
+- ❌ Manually editing migration SQL files
+- ❌ Documenting "delete DB" as a solution
+
+### When Backward Compatibility is NOT Possible
+
+If a breaking change is unavoidable:
+1. **Explicitly communicate**: Document in release notes
+2. **Migration script**: Provide automatic upgrade script
+3. **Version check**: App should check DB version and warn
