v1.3.3 — Security, Performance & Quality

v1.3.3 — Security, Performance & Quality Release

Security

Critical Fixes

• Auth middleware hardened — invalid/expired JWT tokens now return 401 instead of silently passing through. Missing tokens still allowed in open mode.
• WebSocket authentication — server verifies JWT token on connection (/ws?token=<jwt>), rejects invalid tokens with code 4001. Mobile client now sends token on connect.
• ALLOW_ANONYMOUS env var — anonymous access is now explicit opt-in (ALLOW_ANONYMOUS=true by default for backward compatibility). Set to false to require auth on all routes.
• Path traversal fix — scanId in Terry Vision upload is sanitized to alphanumeric characters only.

Hardening

• Helmet security headers — X-Content-Type-Options, X-Frame-Options, Strict-Transport-Security, etc.
• Auth rate limiting — 10 requests/minute on /api/auth/login and /api/auth/register to prevent brute-force.
• Input length validation — recipe title (200 chars), description (2000), notes (2000), ingredients (100 items), steps (100 items), tags (20 items).
• Email format validation on registration endpoint.
• Gemini model list cached server-side (1-hour TTL) — API key no longer sent to clients via proxy.

Database

Performance

• 11 new indexes added (from 2 → 13 total):
  • recipes(user_id), recipes(user_id, updated_at DESC)
  • recipe_images(recipe_id)
  • meal_plans(user_id, date)
  • scanned_items(user_id, consumed, expires_at)
  • push_tokens(user_id), cookbook_entries(user_id)
  • chat_history(user_id, timestamp DESC)
  • dietary_profiles(user_id), terry_vision_scans(user_id), shopping_list(user_id)

Data Integrity

• 9 functions wrapped in transactions: clearStats, addRecipeImage, deleteRecipeImage, deleteCookbookEntry, clearCookbookEntries, deleteTerryVisionScan, clearTerryVisionScans, recordCook, registerPushToken, upsertNotificationSubscription.
• user_id added to UPDATE WHERE clauses in updateRecipe and updateCollection for defense-in-depth.
• Migration system — server/migrations/ directory with migrate.js runner, schema_migrations tracking table, and baseline migration.

Server

Performance

• Async image writes — saveBase64Image converted from writeFileSync to fs.promises.writeFile, no longer blocks the event loop.
• Graceful shutdown — SIGTERM/SIGINT handlers close HTTP server, WebSocket server, and database cleanly.
• WebSocket ping interval .unref()'d so it doesn't prevent process exit.

Architecture

• Shared utilities — isPrivateIP extracted to server/utils.js (was duplicated in index.js and ai.js).
• Config module — magic numbers extracted to server/config.js (rate limits, timeouts, body parser limits, WS ping interval).
• Prompt module — AI prompts extracted to server/prompts.js for easy tuning.
• Request ID middleware — UUID per request attached to req.requestId for log correlation.
• Structured logging — server/logger.js with JSON format in production, pretty in dev, log levels (error/warn/info/debug).
• Enhanced health check — /api/health/detailed reports uptime, DB status, WebSocket connections, memory usage.

Mobile

Stability

• Error boundaries — reusable ErrorBoundary component wraps root navigator and all screen groups. Catches render errors, shows fallback UI with "Try Again" button.
• 42+ empty catch blocks replaced with __DEV__-gated console.warn with context-specific messages.
• 123 console calls gated behind __DEV__ check (no more logs in production builds).

Accessibility

• Accessibility labels added to all interactive elements across 6+ screens: RecipeListScreen, RecipeDetailScreen, EditRecipeScreen, ShoppingListScreen, MealPlannerScreen, CookModeScreen, SettingsScreen, CookbookScreen, BottomNav.
• Includes accessibilityLabel, accessibilityHint, accessibilityRole, and accessibilityState for tabs/checkboxes.

Code Quality

• Deduplicated utilities — splitLines, parseTimerMins, findAllTimers, buildRecipeObject extracted to shared modules.
• expo-image replaces react-native Image in AssistantScreen and SettingsScreen.
• Pressable replaces TouchableOpacity in SwipeableRow for consistency.
• Hardcoded colors in Markdown.js, SwipeableRow.js, VersionBanner.js replaced with theme values.
• Lazy screen loading — heavy screens (TerryVisionScreen, ScanRecipeScreen) use dynamic imports.
• GlobalTimerBar — 1-second interval only runs when active timers exist.
• WebSocket auth — mobile client passes JWT token in connection URL.

DevOps

• GitHub Actions CI/CD — ci.yml (syntax + tests on push/PR), docker.yml (build + push on tag), mobile.yml (expo-doctor on tag).
• Docker — healthcheck fixed, log rotation configured, non-root user, resource limits.

Documentation

• README.md — rewritten with features, tech stack, quick start, architecture overview.
• docs/API.md — all 59 REST API endpoints documented.
• ARCHITECTURE.md — system diagrams, data flows, auth flow, offline strategy, DB schema, security model.
• 22 review reports in reviews/ directory covering code quality, security, database, frontend, DevOps, and performance.

v1.3.0 — Local Nutrition Pipeline & Dietary Intelligence

v1.3.0 — Local Nutrition Pipeline & Dietary Intelligence

Summary

This release transforms Cegin from a recipe manager into a fully offline nutrition-aware cooking app. Every recipe now gets instant macro calculations, allergen warnings, and dietary audit suggestions — all powered by a 2.7MB local USDA database with 14,046 foods. No internet required for nutrition lookups.

Local USDA Nutrition Engine

The biggest feature in this release. A bundled SQLite database containing 14,046 foods from the USDA SR Legacy and Foundation Foods datasets, with full macro data (calories, protein, carbs, fat, fiber) for every entry. The engine uses a 6-strategy search pipeline to match user-written ingredient lines to USDA foods: exact description match, starts-with matching, UK/AU/CA alias matching, FTS5 full-text search, de-pluralization fallback, and last-word fallback. Each food has per-unit gram weights (e.g., 1 cup oats = 81g, not a generic 240g), and the system handles metric volumes (ml/litre), colloquial units ("1 handful", "1 tin"), and count-based items ("2 carrots"). A UK-to-US translation dictionary with 80+ mappings ensures British recipes like "lamb mince" correctly match "ground lamb" in the American database. The entire pipeline runs locally on the device — no server calls, no API keys, no latency.

Instant Allergen Detection

When a recipe loads, the app instantly checks every matched ingredient against a local allergen flags table (7,119 foods flagged). Colored badges appear at the top of the recipe: 🌾 GLUTEN, 🥛 DAIRY, 🥜 NUTS, 🫘 SOY, 🥚 EGGS, 🦐 SHELLFISH. This is completely offline and takes milliseconds — no AI call needed. The flags are based on USDA food categories, not AI guesses, so they're reliable for common whole ingredients.

Terry's Dietary Suggestions

When the dietary audit identifies ingredients that conflict with a profile's needs, Terry now suggests specific substitutions with exact quantities (e.g., "swap 100g butter for 100g ghee"). A new "Apply Terry's Suggestions" button collects all substitutions and opens a picker modal where users can choose between multiple options (e.g., ghee or coconut oil) or add their own custom swaps. When applied, the AI modifies the recipe and opens the editor with Terry's changes highlighted in red — only the new/changed lines appear as red text above each field, and the highlighting clears once the user starts editing. A dark loading overlay with spinner shows while the AI processes. The original recipe image is preserved through the substitution flow.

Pre-processing Pipeline

Before any ingredient line hits the database search, it passes through a multi-stage pre-processor. Compound lines like "For the sauce: 100g butter, 150g dark sugar, 200ml double cream" are split into separate items. Narrative prefixes ("For the filling:", "Toppings:") are stripped. Bracket weights are extracted — "1 tin coconut milk (400ml)" becomes "400ml coconut milk". Prep instructions are trimmed — "500g chicken thighs, diced" becomes "500g chicken thighs". Count-based items get estimated weights — "2 carrots" becomes 120g, "1 clove garlic" becomes 5g. This pre-processing ensures the maximum number of ingredients match the database, which is why nutrition accuracy jumped from ~50% to ~90%+ ingredient coverage.

Dietary Audit Intelligence

The dietary audit now only audits for people in the Health & Diet profiles — Terry never invents names. When all profiles are safe, the audit auto-collapses into a compact green bar ("✓ DIETARY AUDIT — ALL SAFE") that users can tap to expand. The audit prompt now includes explicit instructions to use exact quantities in substitutions and to only return entries for the people listed in the profiles.

• 6-strategy search pipeline — exact match → starts-with → UK/AU/CA alias match → FTS5 full-text → de-pluralization fallback → last-word fallback
• UK-to-US translation dictionary — 80+ mappings: lamb mince→ground lamb, courgette→zucchini, plain flour→all-purpose flour, double cream→heavy cream, etc.
• Global aliases column — foods indexed with UK/AU/CA/CA synonyms for instant cross-locale matching
• Per-food unit conversions — exact USDA gram weights per cup/tbsp/tsp for each specific food (not generic densities)

• FTS5 protein preference — when multiple foods match, prefers entries with actual protein data over sparse Foundation Foods entries

🥗 Instant Allergen Detection

• Local allergen flags — gluten, dairy, nuts, soy, eggs, shellfish detected instantly from USDA database (no API needed)
• Colored badges — 🌾 GLUTEN, 🥛 DAIRY, 🥜 NUTS, 🫘 SOY, 🥚 EGGS, 🦐 SHELLFISH displayed on recipe load
• Batched queries — allergen lookups chunked in groups of 20 to avoid SQLite parameter limits
