Merge branch 'master' into plugin-system-fresh

* Fix is_valid_receipt method bug

Strings submitted with a trailing space and no number caused an unhandled exception because Sale::exists() expects an int but a string was passed to it.

- Add guards
- Minor PSR refactor

 # Agent Instructions
 
-This document provides guidance for AI agents working on the Open Source Point of Sale (OSPOS) codebase.
+This document is the single source of truth for all AI agents working on the Open Source Point of Sale (OSPOS) codebase. Read it fully before making any changes.
+
+## Project Overview
+
+OpenSourcePOS is a web-based Point of Sale system built on **CodeIgniter 4** (PHP 8.2+) with MySQL/MariaDB. Frontend uses Bootstrap 3 (Bootstrap 5 migration in progress) and jQuery, with assets built via Gulp.
+
+## Common Commands
+
+```bash
+# PHP dependencies
+composer install
+
+# Frontend dependencies and asset build
+npm install
+npm run build          # Runs Gulp: compiles and copies all CSS/JS to public/resources/
+
+# Run full test suite
+composer test
+
+# Run a single test file
+vendor/bin/phpunit tests/unit/AppTest.php
+
+# Lint / code style check
+vendor/bin/php-cs-fixer fix --config=.php-cs-fixer.no-header.php --dry-run
+
+# Apply code style fixes
+vendor/bin/php-cs-fixer fix --config=.php-cs-fixer.no-header.php
+```
+
+Tests require a MariaDB/MySQL database (see CI config in `.github/workflows/phpunit.yml`).
+
+## Architecture
+
+### Framework & Entry Point
+
+- **Framework**: CodeIgniter 4 — MVC with QueryBuilder ORM, no Eloquent
+- **Web root**: `public/` — `public/index.php` is the only entry point
+- **Routes**: `app/Config/Routes.php`
+- **App config**: `app/Config/App.php` (version, session, security settings)
+- **Environment**: `.env` file (copy from `.env.example`); `CI_ENVIRONMENT` controls dev/prod/test mode
+
+### Directory Layout
+
+```text
+app/
+├── Config/         # CI4 config classes
+├── Controllers/    # ~27 controllers (Sales, Items, Reports, Customers, etc.)
+├── Models/         # ~28 models (Sale, Item, Customer, Supplier, etc.)
+├── Views/          # PHP view templates
+├── Libraries/      # Business logic (Sale_lib, Tax_lib, Receiving_lib, etc.)
+├── Plugins/        # Plugin system — each plugin is a subdirectory here
+├── Database/       # Migrations (ospos_ prefix) and seeds
+├── Language/       # i18n files (IETF BCP 47 locale names)
+├── Filters/        # Request/response filters (auth, HTTPS, etc.)
+└── Events/         # CI4 event subscribers
+public/
+└── resources/      # Built CSS/JS (do not edit directly — generated by npm run build)
+tests/              # PHPUnit test suite
+```
+
+### Key Libraries
+
+`app/Libraries/` holds core business logic:
+- `Sale_lib.php` — sale cart state, pricing, discounts, tax calculation
+- `Tax_lib.php` — multi-tier tax engine
+- `Receiving_lib.php` — purchase orders / receivings
+- `Barcode_lib.php` — barcode generation
+- `Email_lib.php` — email delivery
+- `Token_lib.php` — CSRF/session token management
+
+### Database
+
+- Table prefix: `ospos_` (defined in `app/Config/Database.php`)
+- Migrations live in `app/Database/Migrations/` and run automatically on first access
+- CodeIgniter QueryBuilder throughout — no raw SQL unless necessary
+
+### Plugin System
+
+Plugins live in `app/Plugins/<PluginName>/` and are auto-discovered by `PluginManager`. Each plugin:
+- Extends `BasePlugin` or implements `PluginInterface`
+- Registers event hooks (e.g., `item_sale`, `customer_saved`, view hooks like `customer_tabs`)
+- Can include its own `Views/`, `Models/`, `Controllers/`, and `Language/` subdirectories
+- Configuration stored in `ospos_plugin_config` table
+- See `app/Plugins/README.md` for plugin structure, event hooks, and LICENSE requirements
+
+### Frontend Build
+
+`gulpfile.js` (Gulp 5) copies vendor CSS/JS from `node_modules/` into `public/resources/`. Run `npm run build` after installing npm packages or changing gulp tasks. Do not manually edit files under `public/resources/`.
 
 ## Code Style
 
-- Follow PHP CodeIgniter 4 coding standards
-- Run PHP-CS-Fixer before committing: `vendor/bin/php-cs-fixer fix --config=.php-cs-fixer.no-header.php`
-- Write PHP 8.1+ compatible code with proper type declarations
-- Use PSR-12 naming conventions: `camelCase` for variables and functions, `PascalCase` for classes, `UPPER_CASE` for constants
+- **PSR-12** enforced via PHP-CS-Fixer (config: `.php-cs-fixer.no-header.php`)
+- `camelCase` for variables and methods; `PascalCase` for classes; `UPPER_CASE` for constants
+- PHP 8.2+ features acceptable (named arguments, enums, readonly properties)
+- Views in `app/Views/errors/html/` are excluded from the fixer
+- Run fixer before committing: `vendor/bin/php-cs-fixer fix --config=.php-cs-fixer.no-header.php`
 
-## Development
+## Development Workflow
 
 - Create a new git worktree for each issue, based on the latest state of `origin/master`
 - Commit fixes to the worktree and push to the remote
-
-## Testing
-
-- Run PHPUnit tests: `composer test`
-- Tests must pass before submitting changes
-
-## Build
-
-- Install dependencies: `composer install && npm install`
-- Build assets: `npm run build` or `gulp`
+- Tests must pass before submitting changes (`composer test`)
+- Minimum PHPUnit version: 10.5.16+. Default config: `phpunit.xml.dist`
 
 ## Conventions
 
-- Controllers go in `app/Controllers/`
-- Models go in `app/Models/`
-- Views go in `app/Views/`
-- Database migrations in `app/Database/Migrations/`
+- Controllers → `app/Controllers/`
+- Models → `app/Models/`
+- Views → `app/Views/`
+- Migrations → `app/Database/Migrations/`
+- Plugins → `app/Plugins/` (see `app/Plugins/README.md` for plugin structure, event hooks, and LICENSE requirements)
 - Use CodeIgniter 4 framework patterns and helpers
 - Sanitize user input; escape output using `esc()` helper
 
 ## Security
 
+- `app.allowedHostnames` **must** be set in production (host header injection protection)
+- HTMLPurifier for HTML sanitization; Laminas Escaper for output escaping

 ## Reporting a Vulnerability
 
-Please report (suspected) security vulnerabilities to **[jeroen@steganos.dev](mailto:jeroen@steganos.dev)**. 
+**Option 1: GitHub Security Advisory (Preferred)**
 
-You will receive a response from us within 48 hours. If the issue is confirmed, we will release a patch as soon as possible depending on complexity but historically within a few days.
+1. Create a draft security advisory directly on GitHub:
+   - Go to https://github.com/opensourcepos/opensourcepos/security/advisories
+   - Click "New draft security advisory"
+   - Fill in the vulnerability details using our [template below](#vulnerability-template)
+   - Submit as **draft** (not published)
+
+2. Notify us for triage:
+   - Send an email to **[jeroen@steganos.dev](mailto:jeroen@steganos.dev)** with:
+     - Subject: `[GHSA] Brief description of vulnerability`
+     - Link to the draft advisory
+     - Brief summary
+
+**Option 2: Email Report**
+
+Send vulnerability details to **[jeroen@steganos.dev](mailto:jeroen@steganos.dev)**.
+
+You will receive a response within 48 hours. Confirmed vulnerabilities will be patched within a few days depending on complexity.
+
+## Disclosure Process
+
+### Timeline
+
+| Step | Timeline | Action |
+|------|----------|--------|
+| 1. Report received | Day 0 | We acknowledge within 48 hours |
+| 2. Triage & confirmation | Day 1-3 | We validate the vulnerability |
+| 3. Fix development | Day 3-7 | We develop and test the fix |
+| 4. Patch release | Day 7-10 | We release a security patch |
+| 5. CVE request | Day 7-14 | We request CVE from GitHub (if applicable) |
+| 6. Advisory published | Day 14 | We publish the advisory with credit |
+| 7. Public disclosure | Day 14+ | Full disclosure after patch release |
+
+### CVE Process
+
+**We request CVE identifiers through GitHub's security advisory system.** This is the preferred and easiest method:
+
+1. After we confirm and fix the vulnerability, we'll request a CVE through GitHub
+2. GitHub coordinates with MITRE on our behalf
+3. The CVE is automatically linked to the advisory
+4. You'll be credited as the reporter in the published advisory
+
+**Already have a CVE?** If you've already obtained a CVE from another source (e.g., VulDB, CVE.MITRE.ORG), please include it in your report or advisory. We'll update our advisory to reference the existing CVE.
+
+### No Bug Bounty Program
+
+**Important:** Open Source Point of Sale does not offer a bug bounty program.
+
+- All security research and vulnerability triage is done on a **voluntary basis** in our free time
+- We do not offer monetary rewards for vulnerability reports
+- We do credit reporters in published advisories (unless anonymity is requested)
+- We greatly appreciate the security research community's efforts to help improve project security
+
+### Security Best Practices for Researchers
+
+- **Do not** access, modify, or delete data that doesn't belong to you
+- **Do not** perform denial of service attacks
+- **Do not** publicly disclose vulnerabilities before we've had time to fix them
+- **Do** provide sufficient information to reproduce the vulnerability
+- **Do** allow us reasonable time to fix before public disclosure
+- **Do** report through official channels (GitHub advisories or email)
+
+### Vulnerability Template
+
+When creating a draft advisory, please include:
+
+```
