v3 port. The Gotenberg PDF driver was missed when the SSRF guards were added
to the AI, exchange-rate and file-disk drivers: gotenberg_host was validated
only with 'url', and the driver POSTs the rendered HTML to it.
Reuses the existing infrastructure (consistency with the other drivers):
- Wires App\Rules\PublicHttpUrl into the gotenberg_host validation rule.
- Adds PrivateNetworkGuard::assertAllowed() in GotenbergPdfDriver before the
outbound call (covers env/seed/stale config + DNS rebinding).
Adds a unit test asserting the gotenberg_host rule rejects private/loopback/
link-local addresses and allows a public one.
Services/Integrations/ExchangeRate/ and Services/Pdf/ were both mostly Support-shaped: interfaces, abstract classes, static factories, concrete adapter drivers, DTOs, and exceptions — infrastructure that doesn't carry business logic. They only each had one real DI-injected service mixed in.
This commit applies the same Services=DI-business-logic / Support=stateless-plumbing rule we've been using throughout the reorg:
**Moved to Support/Integrations/ExchangeRate/** (7 files): ExchangeRateDriver (abstract), ExchangeRateDriverFactory (static), ExchangeRateException, and the four concrete drivers (CurrencyConverter, CurrencyFreak, CurrencyLayer, OpenExchangeRate). These are HTTP adapters over third-party currency APIs — same shape as the Hashids library wrapper classes already in Support.
**Moved to Support/Pdf/** (6 files, merging with existing Pdf utilities): PdfDriver (interface), PdfDriverFactory (static), PdfService (static facade), GotenbergPdfDriver, GotenbergPdfResponse (DTO), ResponseStream (interface). The Support/Pdf/ dir now contains the full PDF rendering subsystem — drivers + sanitizer + template/image utilities.
**Promoted to Services/ root** (the real DI services): ExchangeRateProviderService (CRUD for ExchangeRateProvider model) and FontService (font package install/download orchestration). Both are proper DI services — instance methods, model writes, HTTP side effects.
Services/Integrations/ and Services/Pdf/ are now empty and deleted. Services/ holds only DI-injected classes; Support/ holds all the plumbing.
17 files renamed (git detects 90-99% similarity), 4 consumer files updated (DriverRegistryProvider, PdfServiceProvider, ExchangeRateProviderController, FontController, GeneratesPdfTrait, test). 350 tests pass, Pint clean.
The app/Services/ directory had grown into 22 flat files at the root plus 7 uneven subdirectories — finding anything required scrolling through an alphabetical mix of small CRUD services, infrastructure drivers, and install-time utilities. This commit groups services by domain, folds Backup into a new Storage namespace, and moves framework-infrastructure and install-time helpers out of Services and into Support where they belong.
New Services layout: Documents/ (Invoice, Estimate, RecurringInvoice, Payment, Expense, Transaction, DocumentItem, SerialNumber, Currency — matches the 'Documents' navigation group); Company/ (Company, Member, Invitation); Mail/ (MailConfiguration, CompanyMailConfig); Storage/ (FileDisk, plus Backup folded in). ExchangeRateProviderService moves next to its drivers in ExchangeRate/; FontService moves into Pdf/ where it belongs. CustomerService, ItemService, CustomFieldService stay at the Services root as standalone single-file domains.
Moves to Support/: Hashids/ (library wrapper — not business logic); Setup/ (one-shot install-time utilities — stateless helpers); Pdf/ (ImageUtils, PdfTemplateUtils, plus the existing PdfHtmlSanitizer consolidated into the same subdir). These are all framework infrastructure and stateless utilities — the 'service' label never really fit them.
Namespace declarations in 29 moved files updated to match new paths. 62 consumer files (controllers, other services, tests, database factories, seeders, routes, bootstrap/providers.php) have their use statements rewritten via a literal-string replacement script — no regex meant no risk of half-matching. Three Documents services needed an explicit 'use App\Services\Mail\CompanyMailConfigService' added because the same-namespace short reference they relied on no longer resolves after the split.
Verified: composer dump-autoload, 350 tests pass (850 assertions), vendor/bin/pint clean, npm run build succeeds.
