+# Repository Guidelines
+
+## Project Structure & Module Organization
+- `src/` – app code
+  - `components/` (React, PascalCase files), `pages/` (Astro/API routes), `lib/` (domain + utilities, kebab-case), `hooks/`, `layouts/`, `styles/`, `tests/`, `types/`, `data/`, `content/`.
+- `scripts/` – operational TS scripts (DB init, recovery): e.g., `scripts/manage-db.ts`.
+- `drizzle/` – SQL migrations; `data/` – runtime SQLite (`gitea-mirror.db`).
+- `public/` – static assets; `dist/` – build output.
+- Key config: `astro.config.mjs`, `tsconfig.json` (alias `@/* → src/*`), `bunfig.toml` (test preload), `.env(.example)`.
+
+## Build, Test, and Development Commands
+- Prereq: Bun `>= 1.2.9` (see `package.json`).
+- Setup: `bun run setup` – install deps and init DB.
+- Dev: `bun run dev` – start Astro dev server.
+- Build: `bun run build` – produce `dist/`.
+- Preview/Start: `bun run preview` (static preview) or `bun run start` (SSR entry).
+- Database: `bun run db:generate|migrate|push|studio` and `bun run manage-db init|check|fix|reset-users`.
+- Tests: `bun test` | `bun run test:watch` | `bun run test:coverage`.
+- Docker: see `docker-compose.yml` and variants in repo root.
+
+## Coding Style & Naming Conventions
+- Language: TypeScript, Astro, React.
+- Indentation: 2 spaces; keep existing semicolon/quote style in touched files.
+- Components: PascalCase `.tsx` in `src/components/` (e.g., `MainLayout.tsx`).
+- Modules/utils: kebab-case in `src/lib/` (e.g., `gitea-enhanced.ts`).
+- Imports: prefer alias `@/…` (configured in `tsconfig.json`).
+- Do not introduce new lint/format configs; follow current patterns.
+
+## Testing Guidelines
+- Runner: Bun test (`bun:test`) with preload `src/tests/setup.bun.ts` (see `bunfig.toml`).
+- Location/Names: `**/*.test.ts(x)` under `src/**` (examples in `src/lib/**`).
+- Scope: add unit tests for new logic and API route tests for handlers.
+- Aim for meaningful coverage on DB, auth, and mirroring paths.
+
+## Commit & Pull Request Guidelines
+- Commits: short, imperative, scoped when helpful (e.g., `lib: fix token parsing`, `ui: align buttons`).
+- PRs must include:
+  - Summary, rationale, and testing steps/commands.
+  - Linked issues (e.g., `Closes #123`).
+  - Screenshots/gifs for UI changes.
+  - Notes on DB/migration or .env impacts; update `docs/`/CHANGELOG if applicable.
+
+## Security & Configuration Tips
+- Never commit secrets. Copy `.env.example` → `.env` and fill values; prefer `bun run startup-env-config` to validate.
+- SQLite files live in `data/`; avoid committing generated DBs.
+- Certificates (if used) reside in `certs/`; manage locally or via Docker secrets.

+
+## Project Overview
+
+Gitea Mirror is a self-hosted web application that automatically mirrors repositories from GitHub to Gitea instances. It's built with Astro (SSR mode), React, and runs on the Bun runtime with SQLite for data persistence.
+
+**Key capabilities:**
+- Mirrors public, private, and starred GitHub repos to Gitea
+- Supports metadata mirroring (issues, PRs as issues, labels, milestones, releases, wiki)
+- Git LFS support
+- Multiple authentication methods (email/password, OIDC/SSO, header auth)
+- Scheduled automatic syncing with configurable intervals
+- Auto-discovery of new repos and cleanup of deleted repos
+- Multi-user support with encrypted token storage (AES-256-GCM)
+

+
+### Key Architectural Patterns
+
+#### 1. Database Schema and Validation
+- **Location:** `src/lib/db/schema.ts`
+- **Pattern:** Drizzle ORM tables + Zod schemas for validation
+- **Key tables:**
+  - `configs` - User configuration (GitHub/Gitea settings, mirror options)
+  - `repositories` - Tracked repositories with metadata
+  - `organizations` - GitHub organizations with destination overrides
+  - `mirrorJobs` - Mirror job queue and history
+  - `activities` - Activity log for dashboard
+  - `user`, `session`, `account` - Better Auth tables
+
+**Important:** All config tokens (GitHub/Gitea) are encrypted at rest using AES-256-GCM. Use helper functions from `src/lib/utils/config-encryption.ts` to decrypt.
+
+#### 2. Mirror Job System
+- **Location:** `src/lib/helpers.ts` (createMirrorJob)
+- **Flow:**
+  1. User triggers mirror via API endpoint
+  2. `createMirrorJob()` creates job record with status "pending"
+  3. Job processor (in API routes) performs GitHub → Gitea operations
+  4. Job status updated throughout: "mirroring" → "success"/"failed"
+  5. Events published via SSE for real-time UI updates
+
+#### 3. GitHub ↔ Gitea Mirroring
+- **GitHub Client:** `src/lib/github.ts` - Octokit with rate limit tracking
+- **Gitea Client:** `src/lib/gitea.ts` - Basic repo operations
+- **Enhanced Gitea:** `src/lib/gitea-enhanced.ts` - Metadata mirroring (issues, PRs, releases)
+
+**Mirror strategies (configured per user):**
+- `preserve` - Maintain GitHub org structure in Gitea
+- `single-org` - All repos into one Gitea org
+- `flat-user` - All repos under user account
+- `mixed` - Personal repos in one org, org repos preserve structure
+
+**Metadata mirroring:**
+- Issues transferred with comments, labels, assignees
+- PRs converted to issues (Gitea API limitation - cannot create PRs)
+  - Tagged with "pull-request" label
+  - Title prefixed with `[PR #number] [STATUS]`
+  - Body includes commit history, file changes, merge status
+- Releases mirrored with assets
+- Labels and milestones preserved
+- Wiki content cloned if enabled
+- **Sequential processing:** Issues/PRs mirrored one at a time to prevent out-of-order creation (see `src/lib/gitea-enhanced.ts`)
+
+#### 4. Scheduler Service
+- **Location:** `src/lib/scheduler-service.ts`
+- **Features:**
+  - Cron-based or interval-based scheduling (uses `duration-parser.ts`)
+  - Auto-start on boot when `SCHEDULE_ENABLED=true` or `GITEA_MIRROR_INTERVAL` is set
+  - Auto-import new GitHub repos
+  - Auto-cleanup orphaned repos (archive or delete)
+  - Respects per-repo mirror intervals (not Gitea's default 24h)
+- **Concurrency control:** Uses `src/lib/utils/concurrency.ts` for batch processing
+
+#### 5. Authentication System
+- **Location:** `src/lib/auth.ts`, `src/lib/auth-client.ts`
+- **Better Auth integration:**
+  - Email/password (always enabled)
+  - OIDC/SSO providers (configurable via UI)
+  - Header authentication for reverse proxies (Authentik, Authelia)
+- **Session management:** Cookie-based, validated in Astro middleware
+- **User helpers:** `src/lib/utils/auth-helpers.ts`
+
+#### 6. Environment Configuration
+- **Startup:** `src/lib/env-config-loader.ts` + `scripts/startup-env-config.ts`
+- **Pattern:** Environment variables can pre-configure settings, but users can override via web UI
+- **Encryption:** `ENCRYPTION_SECRET` for tokens, `BETTER_AUTH_SECRET` for sessions
+
+#### 7. Real-time Updates
+- **Events:** `src/lib/events.ts` + `src/lib/events/realtime.ts`
+- **Pattern:** Server-Sent Events (SSE) for live dashboard updates
+- **Endpoints:** `/api/sse` - client subscribes to job/repo events
+
+### Testing Patterns
+
+**Unit tests:**
+- Colocated with source: `filename.test.ts` alongside `filename.ts`
+- Use Bun's built-in assertions and mocking
+- Mock external APIs (GitHub, Gitea) using `src/tests/mock-fetch.ts`
+
+**Integration tests:**
+- Located in `src/tests/`
+- Test database operations with in-memory SQLite
+- Example: `src/lib/db/index.test.ts`
+
+**Test utilities:**
+- `src/tests/setup.bun.ts` - Global test setup (loaded via bunfig.toml)
+- `src/tests/mock-fetch.ts` - Fetch mocking utilities
+
+### Important Development Notes
+
+1. **Path Aliases:** Use `@/` for imports (configured in `tsconfig.json`)
+   ```typescript
+   import { db } from '@/lib/db';
+   ```
+
+2. **Token Encryption:** Always use encryption helpers when dealing with tokens:
+   ```typescript
+   import { getDecryptedGitHubToken, getDecryptedGiteaToken } from '@/lib/utils/config-encryption';
+   ```
+
+3. **API Route Pattern:** Astro API routes in `src/pages/api/` should:
+   - Check authentication via Better Auth
+   - Validate input with Zod schemas
+   - Handle errors gracefully
+   - Return JSON responses
+
+4. **Database Migrations:**
+   - Schema changes: Update `src/lib/db/schema.ts`
+   - Generate migration: `bun run db:generate`
+   - Review generated SQL in `drizzle/` directory
+   - Apply: `bun run db:migrate` (or `db:push` for dev)
+
+5. **Concurrency Control:**
+   - Use utilities from `src/lib/utils/concurrency.ts` for batch operations
+   - Respect rate limits (GitHub: 5000 req/hr authenticated, Gitea: varies)
+   - Issue/PR mirroring is sequential to maintain chronological order
+
+6. **Duration Parsing:**
+   - Use `parseInterval()` from `src/lib/utils/duration-parser.ts`
+   - Supports: "30m", "8h", "24h", "7d", cron expressions, or milliseconds
+
+7. **Graceful Shutdown:**
+   - Services implement cleanup handlers (see `src/lib/shutdown-manager.ts`)
+   - Recovery system in `src/lib/recovery.ts` handles interrupted jobs
+
+## Common Development Workflows
+
+### Adding a new mirror option
+1. Update Zod schema in `src/lib/db/schema.ts` (e.g., `giteaConfigSchema`)
+2. Update TypeScript types in `src/types/config.ts`
+3. Add UI control in settings page component
+4. Update API handler in `src/pages/api/config/`
+5. Implement logic in `src/lib/gitea.ts` or `src/lib/gitea-enhanced.ts`
+
+### Debugging mirror failures
+1. Check mirror jobs: `bun run db:studio` → `mirrorJobs` table
+2. Review activity logs: Dashboard → Activity tab
+3. Check console logs for API errors (GitHub/Gitea rate limits, auth issues)
+4. Use diagnostic scripts: `bun run test-recovery`
+
+### Adding authentication provider
+1. Update Better Auth config in `src/lib/auth.ts`
+2. Add provider configuration UI in settings
+3. Test with `src/tests/test-gitea-auth.ts` patterns
+4. Update documentation in `docs/SSO-OIDC-SETUP.md`
+
