+Scanlook (current product summary)
 
-## Scanlook (current product summary)
-Scanlook is a modular inventory management platform for warehouse operations.
+Scanlook is a modular inventory management platform for warehouse operations. Current Focus: Implementing "Smart Scanning" workflows that dynamically route scans based on regex rules to handle complex data (like Data Matrix codes) vs simple manual entry.
+Operating rules (must follow)
 
-Long-term goal: evolve into a full WMS, but right now focus on making workflows reliable and the module system robust.
+    Be accurate, not fast. Double-check code, SQL, and commands before sending.
 
-## Operating rules (must follow)
-1) **Be accurate, not fast.** Double-check code, SQL, and commands before sending.
-2) **No assumptions about files/environment.** If you need code, schema, logs, config, versions, or screenshots, ask me to paste/upload them.
-3) **Step-by-step only.** I'm a beginner: give ONE small step at a time, then wait for my result before continuing.
-4) **No command dumps.** Don't give long chains of commands. One command (or tiny set) per step.
-5) **Keep it to the point.** Default to short answers. Only explain more if I ask.
-6) **Verify safety.** Warn me before destructive actions (delete/overwrite/migrations). Offer a safer alternative.
-7) **Evidence-based debugging.** Ask for exact error text/logs and versions before guessing.
-8) **CSS changes:** Ask which device(s) the change is for (desktop/mobile/scanner) before editing. Each has its own file.
-9) **Docker deployment:** Production runs in Docker with Gunicorn on Linux (PortainerVM). Volume mounts only /app/database to preserve data between updates.
-10) **Database changes:** Never tell user to "manually run SQL". Always add changes to migrations.py so they auto-apply on deployment.
+    No assumptions about files/environment. If you need code, schema, logs, config, versions, or screenshots, ask me to paste/upload them.
 
-## How you should respond
-- Ask for the minimum needed info (3–6 questions max), then propose the next single step.
-- When writing code: keep it small, readable, and consistent with Flask best practices.
-- When writing SQL: be explicit about constraints/indexes that matter for lots/bins/sessions.
-- When talking workflow: always keep session isolation (shift-based counts) as a hard requirement.
+    Step-by-step only. I'm a beginner: give ONE small step at a time, then wait for my result before continuing.

-**Current Version:** 0.17.1
+    Keep it to the point. Default to short answers. Only explain more if I ask.
 
-**Tech Stack:**
-- Backend: Python 3.13, Flask, Gunicorn (production WSGI server)
-- Database: SQLite (located in /database/scanlook.db)
-- Frontend: Jinja2 templates, vanilla JS, custom CSS
-- CSS Architecture: Desktop-first with device-specific overrides
-  - style.css (base/desktop)
-  - mobile.css (phones, 360-767px)
-  - scanner.css (MC9300 scanners, max-width 359px)
-- Deployment: Docker container with Gunicorn, Gitea for version control + container registry
+    Verify safety. Warn me before destructive actions (delete/overwrite/migrations). Offer a safer alternative.
 
-**Project Structure:**
-- app.py (main Flask app, core routes, module loading)
-- /blueprints/users.py (user management blueprint - non-modular)
-- /modules/ (modular applications - invcount, conssheets)
-  - Each module has: __init__.py, routes.py, migrations.py, manifest.json, templates/
-- /templates/ (core templates: login.html, home.html, base.html, admin_dashboard.html, module_manager.html)
-- /static/css/ (style.css, mobile.css, scanner.css)
-- /database/ (scanlook.db, init_db.py)
-- db.py (database helper functions: query_db, execute_db, get_db)
-- utils.py (decorators: login_required, role_required)
-- migrations.py (core database migrations)
-- module_manager.py (ModuleManager class - handles module lifecycle)
-- Dockerfile (Python 3.13-slim, Gunicorn with 4 workers)
-- docker-compose.yml (orchestrates scanlook container with volume for database)
-- gunicorn_config.py (Gunicorn hooks for module loading in workers)
+    Evidence-based debugging. Ask for exact error text/logs and versions before guessing.
 
-**Module System (v0.17.0+):**
-- **Modular Architecture:** Each module is a self-contained plugin with its own routes, templates, migrations
-- **Module Structure:** 
-  - manifest.json (metadata: name, version, author, icon, description)
-  - __init__.py (creates blueprint via create_blueprint())
-  - routes.py (defines register_routes(bp) function)
-  - migrations.py (get_schema(), get_migrations())
-  - templates/{module_key}/ (module-specific templates)
-- **Module Manager UI:** /admin/modules - install/uninstall/activate/deactivate modules
-- **Module Upload:** Drag-and-drop ZIP upload to add new modules
-- **Module Installation:** Creates database tables, registers in Modules table, grants access to users
-- **Module Uninstall:** Triple-confirmation flow, always deletes data (deactivate preserves data)
-- **Auto-restart:** After module install, server restarts to load new routes
-  - Dev (Flask): Thread-based restart via os.execv()
-  - Production (Gunicorn): HUP signal to master for graceful worker reload
-- **Database Tables:**
-  - Modules (module_id, name, module_key, version, author, description, icon, is_active, is_installed)
-  - UserModules (user_id, module_id) - grants access per user
+    CSS changes: Ask which device(s) the change is for (desktop/mobile/scanner) before editing. Each has its own file.
 
-**Current Modules:**
-1. **Inventory Counts (invcount)** - Cycle counts and physical inventory
-   - Routes: /invcount/
-   - Tables: LocationCounts, ScanEntries, Sessions, etc.
-2. **Consumption Sheets (conssheets)** - Production lot tracking with Excel export
-   - Routes: /conssheets/
-   - Tables: cons_processes, cons_sessions, cons_process_fields, etc.
+    Docker deployment: Production runs in Docker with Gunicorn on Linux (PortainerVM). Volume mounts only /app/database to preserve data between updates.
 
-**Key Features:**
-- Modular plugin architecture with hot-reload capability
-- Module Manager with drag-and-drop upload
-- Session-based counting workflows with archive/activate
-- Master/current baseline upload (CSV)
-- Staff scanning interface optimized for MC9300 Zebra scanners
-- Scan statuses: Match, Duplicate, Wrong Location, Ghost Lot, Weight Discrepancy
-- Role-based access: owner, admin, staff
-- Auto-initialize database on first run
-- Database migration system (auto-applies schema changes on startup)
-- Production-ready with Gunicorn multi-worker support
+    Database changes: Never tell user to "manually run SQL". Always add changes to migrations.py so they auto-apply on deployment.
 
-**Development vs Production:**
-- **Dev:** Windows, Flask dev server (python app.py), auto-reload on file changes
-- **Production:** Linux Docker container, Gunicorn with 4 workers, graceful reloads via HUP signal

+Smart Router Engine (v0.18.0+):
+
+    Concept: A "Universal Pipeline" that processes scans based on Regex matching.
+
+    Workflow:
+
+        Router (routes.py): Matches barcode to a Rule (e.g., Rule 10=Manual, Rule 20=DataMatrix).
+
+        Engine (global_actions.py): Executes a JSON chain of actions:
+
+            MAP: Extracts data (Lot, Weight) using fixed slicing or regex.
+
+            CLEAN: Formats data (Trim, Remove Zeros).
+
+            DUPLICATE: Checks DB. Can BLOCK or WARN. (Pause & Resume supported).
+
+            INPUT: Checks if data is missing. PAUSES execution to open Frontend Modal. RESUMES when User clicks Save.
+
+            SAVE: Commits clean data to the module's detail table.
+
+    Frontend (scan_session.html): Handles needs_input signals to open modals and sends extra_data back to the engine to resume processing.
+
+Module System (v0.17.0+):
+
+    Modular Architecture: Each module is a self-contained plugin with its own routes, templates, migrations
+
+    Module Manager UI: /admin/modules - install/uninstall/activate/deactivate modules

+
+        Routes: /conssheets/
+
+        Tables: cons_processes, cons_sessions, cons_proc_{key}_details, cons_process_router
