+# BeepZone Inverory Setup Helper Scripts and Database Files
+Huh so you want to actually try beepzone? (Oh god)
+
+Well then since I have no setup guides tbh I'll provide a bash script here to build and get you started, do not use this in Prod like at all I dont recommend my own software for such things in general tbh.
+
+## Whats in this repository?
+- Database Schema and Dumps from Dev Environement
+- Helper Script to get you started and do some basic user management as no client can do so yet lol
+
+what does the script do ?
+
+helps you get started by priividing an assistive TUI for :
+- running a podman container with mariadb and
+    - letting you configure access details
+    - importing the schema
+    - managing users and roles in the db (create/delete both with bcrypt password hashing)
+    - optionally import some seeding data
+- compiling and setting up SeckelAPI to be able to talk with mariadb
+    - either as a podman container (recommended, uses proper port mapping 5777:5777 and host gateway for db access)
+    - or natively on the system (for dev work)
+    - auto-configures database connection settings
+- compiling the desktop client so you can start beepin
+
+someday once i consider em release worthy it will also obviously be able to compile the terminal/kiosk/embedded client aswell as the mobile app 
+
+a real installer that is not just a setup bash script is planned but thats far into the future idk when 
+
+Setup Scripts currently do not support windows
+
+requirements for script:
+- mac
+    - podman installed and configured (podman-desktop recommended for dev work)
+    - brew installed
+    - mysql-client installed (brew install mysql-client -> script auto detects /opt/homebrew/opt/mysql-client/bin/)
+    - rust and tools installed via rustup
+    - dialog for TUI (brew install dialog)
+- linux
+    - any debian based distro (if not, install dependencies yourself)
+    - mariadb-client installed (apt-get install mariadb-client)
+    - rust and tools installed via rustup
+    - podman installed and configured (podman-desktop recommended for dev work)
+    - dialog for TUI (apt-get install dialog)
+
+internet access too obviously to pull em sources :
+https://git.teleco.ch/crt/beepzone-client-egui-emo.git
+https://git.teleco.ch/crt/seckelapi.git
+
+## how to use
+
+just run the helper script:
+```bash
+./beepzone-helper.sh
+```
+
+it will guide you through:
+1. configuring and running mariadb in podman
+2. importing the database schema (dumped version with all updates)
+3. very basics of managing users and roles (create/delete users/roles with power level 1-100)
+4. setting up SeckelAPI (container deployment recommended)
+5. building the desktop client
+
+the script stores config in `.env` file and auto-detects installed tools in common locations
+
+## container stuff
+
+- mariadb container: exposes port 3306, persists data
+- seckelapi container: uses rust 1.92 + debian trixie, port 5777:5777, connects to mariadb via host.containers.internal
+- both use latest stable base images
+
+## notes
+
+- passwords are hashed with bcrypt cost 12 using htpasswd or python bcrypt fallback
+- database config auto-updates when building containers (uses host.containers.internal for db host)
+- native builds use localhost for db access
+- run scripts provided: ./run-seckelapi.sh and ./run-client.sh (execute from sources/ dir)

+/*
+HOW TO USE FROM YOUR RUST PROXY:
+
+Before any INSERT/UPDATE/DELETE operation, set the user context:
+    SET @current_user_id = 123;
+
+Then execute your query normally. The triggers will automatically:
+1. Auto-populate user tracking fields (if not explicitly provided):
+   • assets.created_by (on INSERT)
+   • assets.last_modified_by (on UPDATE)
+   • borrowers.added_by (on INSERT)
+   • borrowers.last_unban_by (on UPDATE when unbanning)
+   • issue_tracker.reported_by (on INSERT)
+2. Log changes to asset_change_log EFFICIENTLY:
+   • INSERT: Only logs fields that were actually set (non-NULL)
+   • UPDATE: Only logs fields that actually changed
+   • DELETE: Only logs fields that had values (non-NULL) for restore capability
+3. Include user_id and username in logs
+4. Update last_modified_by and last_modified_date automatically
+5. Enforce business rules (prevent deleting borrowed items, validate zone_plus, etc.)
+6. Auto-calculate quantities for lendable items with quantity tracking
+7. Auto-detect and track issues in issue_tracker
+8. Manage physical audits with automatic issue detection
+
+NOTE: You can still explicitly provide user tracking fields in your queries if needed.
+      The triggers only set them if they are NULL and @current_user_id is available.
+
+EFFICIENCY: Change logging only captures non-NULL/changed fields, reducing storage by ~80%
+            for typical operations. The 'changed_fields' JSON array shows exactly what was
+            set/changed/deleted, making audit logs cleaner and more queryable.
+
+PHYSICAL AUDIT WORKFLOW:
+1. Start audit: INSERT INTO physical_audits (audit_type, zone_id, started_by) VALUES ('full-zone', 1, 123);
+2. Scan assets: INSERT INTO physical_audit_logs (physical_audit_id, asset_id, audited_by, status_found, audit_task_id, audit_task_responses, exception_type, found_in_zone_id, auditor_action) VALUES (...);
+3. Complete audit: UPDATE physical_audits SET status = 'all-good' (or 'attention') WHERE id = audit_id;
+4. System automatically creates issues for missing/moved/damaged assets
+
+WRONG-ZONE ASSET HANDLING:
+When asset found in wrong zone (exception_type = 'wrong-zone'), auditor has 3 options:
+- auditor_action = 'physical-move': Auditor will physically move item to correct zone (no issue created)
+- auditor_action = 'virtual-update': Update asset's zone in system to where found (auto-detects label reprinting needs)
+- auditor_action = NULL: Creates standard follow-up issue for later resolution
+
+LABEL REPRINTING DETECTION:
+System automatically detects if asset_tag contains location info when doing virtual-update:
+- Checks if asset_tag contains old zone name or room codes
+- Checks for common label patterns (e.g., "MB101-001", "RoomA-Device")  
+- Creates 'Maintenance' issue with 'Low' priority for label reprinting if needed
+
+CROSS-AUDIT RECONCILIATION:
+System automatically resolves "missing asset" issues from previous audits when assets are found:
+- When asset is scanned in any audit, checks if it was missing from previous completed audits
+- Auto-resolves related missing asset issues with solution 'Automatically Fixed'
+- Logs reconciliation activity in asset_change_log for audit trail
+- Prevents false "missing" reports when assets are just in different locations
+
+ISSUE TRACKER FEATURES:
+- Auto-creates issues for problematic asset status changes
+- Auto-resolves issues when assets return to Good status
+- Tracks borrower ban/unban cycles
+- Comprehensive audit issue detection and tracking
+- Intelligent cross-audit reconciliation to prevent false missing asset reports
+
+Example queries in asset_change_log:
+- changed_fields: ["status", "zone_id"] (array of field names that changed)
+- old_values: {"status": "Good", "zone_id": 5}
+- new_values: {"status": "Faulty", "zone_id": 7}
+
+Example audit_task_responses JSON:
+{"step_1_answer": "yes", "step_2_answer": "Good", "damage_notes": "Minor scratches on case"}
+
+Example issues_found JSON in physical_audits:
+{"missing_assets": 2, "moved_assets": 5, "damaged_assets": 1, "total_issues": 8}
