CHANGELOG — Corrosion Admin Panel

All notable changes to this project will be documented in this file.

[Unreleased]

Added (Phase 4 — Module Licensing Backend)

Backend Infrastructure:

• Migration 009_module_licensing.sql — Module marketplace database schema:

  • module_purchases table — License-module ownership tracking with transaction logging
  • module_installations table — Deployment status tracking (pending, installing, installed, failed)
  • Seed data: Loot Manager module ($9.99) with features array
• backend/src/models/modules.rs — Domain models:
  • Module struct with rust_decimal pricing support
  • ModuleWithOwnership — Catalog display with is_purchased flag
  • ModulePurchase, ModuleInstallation — Purchase and deployment records
  • PurchasedModule — Combined view for user's module library
• backend/src/db/modules.rs — Data access layer (11 query functions):
  • get_module_catalog() — All available modules
  • get_catalog_with_ownership(license_id) — Annotated catalog with purchase status
  • get_purchased_modules(license_id) — User's module library with installation status
  • is_module_purchased(license_id, module_id) — Ownership validation
  • record_module_purchase() — Transaction logging with PayPal ID support
  • get_module_installation_status() / update_installation_status() — Deployment tracking
  • get_module_by_id() / get_module_by_slug() — Module lookup
• backend/src/api/modules.rs — REST endpoints with auth middleware:
  • GET /api/modules/catalog — Returns modules with is_purchased flag for current license
  • GET /api/modules/my-modules — Purchased modules with installation details
  • POST /api/modules/purchase — Records purchase (stub transaction for Phase 4 MVP — payment integration deferred to XO's direct touch)

  • GET /api/modules/:module_id/installation-status — Real-time deployment status polling
• Router integration in main.rs at /api/modules with JWT auth requirement

Multi-Tenancy Enforcement:

• All queries scoped by license_id from JWT claims
• Foreign key constraints enforce license-module binding
• Purchase validation prevents cross-tenant access
• Installation status isolated per license

Payment Integration Strategy:

• Purchase endpoint stubs transaction with "STUB_TRANSACTION" ID
