Rewires module installation to use slug + version + checksum_sha256 instead of the opaque module identifier. ModuleInstaller splits marketplace token handling out of install() into helpers, adopts structured error responses, and validates the downloaded archive's SHA-256 against the marketplace manifest before unpacking.
ModuleResource is simplified to accept an already-loaded installed-module instance rather than fetching it from state, exposes access_tier and checksum fields, and drops the auto-disable-on-unpurchased side effect that was bleeding write logic into a read resource. UnzipUpdateRequest accepts a nullable module with a conditional module_name field so the same endpoint serves both app and module updates.
ModulesPolicy::manageModules now short-circuits for super-admins so administration flows (token validation, store state) are not blocked on a company-scoped ability. Two new feature tests cover both the authorization bypass and ModuleResource serialization.
Relocate all 14 files from the catch-all app/Space namespace into proper
locations: data providers to Support/Formatters, installation utilities to
Services/Installation, PDF utils to Services/Pdf, module/update classes to
Services/Module and Services/Update, SiteApi trait to Traits, and helpers
to Support.
Extract ~1,400 lines of business logic from 8 fat models (Invoice, Payment,
Estimate, RecurringInvoice, Company, Customer, Expense, User) into 9 new
service classes with constructor injection. Controllers now depend on
services instead of calling static model methods. Shared item/tax creation
logic consolidated into DocumentItemService.
