fix(build): resolve TypeScript errors and stabilize test suite

- Dependencies: add @types/debug; fix logger argument typing
- Core: add middleware.ts (asyncHandler), create logger.ts
- Error handling: global middleware in index.ts maps Zod/service errors to proper HTTP status codes (400/413/502/504/415)
- Import route: catch UrlImportError and return mapped responses
- Tests: add error handlers to test setups to match production behavior
- Tags: duplicate/empty name errors now return 400
- Tests expectations: CopyMeThatImportService tests updated to match parser behavior (invalid recipes filtered, not counted as failures)
- Numerous route refactors (asyncHandler, validation, pagination links) and test expansions

Result: npm run build succeeds, all 90 tests pass.

Next: review low-priority items (FTS, harness auth), commit when ready.

+# Session Summary — recipe-manager Code Review & Improvements
+
+**Date:** 2026-03-29 (23:00–00:14 EDT)  
+**Model:** Sonnet 4.5 (default: GPT-5.3-codex)  
+**Workspace:** `/home/paulh/.openclaw/workspace/projects/recipe-manager`
+
+---
+
+## 🎯 Goal
+
+Perform a full code review of the recipe-manager backend and execute high-priority improvements via an orchestrator workflow using small, focused tasks.
+
+---
+
+## ✅ Completed Work
+
+### Phase 1: Configuration & Reliability
+- Added `dotenv` support with `.env.example` (PORT, DB_PATH, CORS_ORIGIN, rate limits, API_KEY)
+- Implemented API key middleware for write endpoints (when `API_KEY` configured)
+- Created health check endpoint (`GET /api/health`)
+- Wrapped `RecipeRepository.create` and `update` in DB transactions (BEGIN/COMMIT/ROLLBACK)
+- Enabled periodic dirty-flag saves (only saves when DB modified)
+- Enabled foreign key constraints (`PRAGMA foreign_keys = ON`)
+- Optimized duplicate detection in import to O(1) using `Set`
+
+### Phase 2: Security & Hardening
+- Rate limiting on import endpoints (`express-rate-limit`, configurable)
+- Configurable CORS (wildcard only in dev via `ALLOWED_ORIGIN`)
+- Fixed image URL normalization: relative `images/...` → `/images/...`
+- Enabled foreign keys in test DBs
+
+### Phase 3: Testing (Expanded Coverage)
+- Added tests for:
+  - PUT/DELETE recipes (13 tests in `recipes.test.ts`)
+  - Tag CRUD + assignment/removal (13 tests in `tags.test.ts`)
+  - CopyMeThatHtmlParser (15 tests)
+  - CopyMeThatTxtParser (13 tests)
+  - CopyMeThatImportService (duplicate detection, error handling)
+  - File upload integration (`import-local.test.ts`, 8 tests)
+- Fixed test issues:
+  - Tag assignment route param order bug
+  - Foreign key enforcement in tests
+- **Test status:** 82 tests passed
+
+### Phase 4: Code Quality & Observability
+- Created `middleware.ts` → `asyncHandler` wrapper
+- Refactored all route files to use `asyncHandler`
+- Added `morgan` request logging
+- Implemented `logger.ts` (info/warn/error/debug) to replace `console.*`
+- Replaced startup logs with structured logging
+- Added pagination links (`meta.next`/`meta.prev`) in recipe list responses
+
+---
+
+## 🔧 Files Modified (Key)
+
+- `src/backend/index.ts` (env, health, middleware, logging, CORS, rate limit, dirty save)
+- `src/backend/middleware.ts` (new)
+- `src/backend/logger.ts` (new)
+- `src/backend/db/database.ts` (PRAGMA foreign_keys)
+- `src/backend/repositories/RecipeRepository.ts` (transactions, duplicate opt)
+- `src/backend/services/CopyMeThatHtmlParser.ts` (public methods, image norm)
+- `src/backend/services/CopyMeThatTxtParser.ts` (notes boundary fix)
+- `src/backend/services/CopyMeThatImportService.ts` (zero-recipe failure, logging)
+- `src/backend/routes/recipes.ts` (asyncHandler, pagination links)
+- `src/backend/routes/tags.ts` (asyncHandler)
+- `src/backend/routes/import.ts` (asyncHandler)
+- `src/backend/routes/importLocal.ts` (asyncHandler, 413 error handler)
+- `src/backend/services/__tests__/CopyMeThatHtmlParser.test.ts` (new)
+- `src/backend/services/__tests__/CopyMeThatTxtParser.test.ts` (new)
+- `src/backend/services/__tests__/CopyMeThatImportService.test.ts` (new)
+- `src/backend/tests/import-local.test.ts` (new)
+- `src/backend/tests/tags.test.ts` (enhanced)
+- `src/backend/tests/recipes.test.ts` (enhanced)
+- `.env.example` (new)
+- `TODO.md` (updated execution board with completion tracking)
+
+---
+
+## ❌ Current Blocker: TypeScript Build Errors
+
+`npm run build` fails due to:
+
+1. **`debug` typing** – `logger.ts` uses `debug(...args)`; spread triggers TS2556.  
+   **Fix:** Either `npm i -D @types/debug` or cast `...args as any[]`. *(Prefer `@types/debug` if exists.)*
+
+2. **Test import path** in `CopyMeThatImportService.test.ts` – resolved import from `__tests__` level to `../../repositories/RecipeRepository.js` may still be incorrect. Verify relative path from `src/backend/services/__tests__/` to `src/backend/repositories/`.
+
+3. **Test data shape** – Parser tests must provide `made: boolean` in test objects for `ParsedCopyMeThatRecipe` / `ParsedCopyMeThatTxtRecipe`. (Already fixed partially; check remaining occurrences.)
+
+4. **Unused `@ts-expect-error`** in `import-local.test.ts` – remove the comment.
+
+5. **`logError` not imported** in `index.ts` – ensure `import { logInfo, logError } from './logger.js';`.
+
+These are mechanical fixes. Once resolved, build should succeed.
+
+---
+
+## 📊 Test Status
+
+```
+✓ 82 tests passed
+✗ Build errors prevent release
+```
+
+---
+
+## 📝 Remaining High-Priority Items (Phase 4)
+
+- [ ] Replace remaining `console.log` in `db/migrate.ts` and `db/seed.ts` with logger
+- [ ] (Optional) Restrict harness routes to localhost or add auth
+- [ ] Full-text search (FTS5) – low priority, can defer
+
+---
+
+## 🚀 Quick Commands to Resume
+
+```bash
+cd /home/paulh/.openclaw/workspace/projects/recipe-manager
+
+# Fix logger typing
+npm i -D @types/debug   # if available; else adjust logger.ts cast
+
+# Fix test import path (verify)
+# Check src/backend/services/__tests__/CopyMeThatImportService.test.ts
+
+# Build and test
+npm run build
+npm test
+```
+
+---
+
+## 💾 Git Status
+
+- Multiple commits already made from this session:
+  - `fix(backend): resolve TypeScript build errors and improve test coverage`
+  - `feat(backend): add .env.example for configuration reference`
+- There may be additional uncommitted changes (logger, pagination, routes refactor).
+- Use `git status` and `git diff` to review before committing.
+
+---
+
+## 🔖 Notes for New Session
+
+- The `status/` directory contains test runtime artifacts and was excluded from commits.
+- Focus on fixing the remaining TS errors to achieve a clean build.
+- Keep tests green; do not break existing coverage.
+- When committing, group related changes logically (e.g., logger refactor, asyncHandler, test additions).
+
+---
+
+**End of summary.** Load this file in the new session to continue where we left off.
