Foundation for the AI chatbot + text generation feature. Phase 1 is infrastructure only: driver plumbing, configuration storage with encrypted API keys, global vs per-company resolution, admin + company UI pages, and an optional installer wizard step. The chat assistant and text-generation WYSIWYG integration come in later phases.
**Driver plumbing (app/Support/Ai/)** — AiDriver abstract, AiDriverFactory, AiException, AiChatResponse DTO, OpenRouterDriver concrete implementation. OpenRouter is the OpenAI-compatible aggregator that unlocks hundreds of models behind one API key and one request shape — ideal as the default v1 driver. Drivers are extensible the same way exchange rate drivers are: the module Registry's generic registerDriver('ai', ...) machinery plus a typed Registry::registerAiDriver() convenience wrapper (shipped in the upstream invoiceshelf/modules package in a paired commit).
**AiConfigurationService** — mirrors MailConfigurationService shape but with one deliberate deviation: API keys are encrypted at the service layer via Crypt::encryptString before persistence. OpenRouter bearer tokens have much bigger blast radius than SMTP passwords. Same settings / company_settings tables, same global-vs-per-company pattern, same use_custom_ai_config override toggle. Resolution order: global ai_enabled must be YES, then the company either overrides via use_custom_ai_config=YES (and can opt out with ai_enabled=NO inside the override) or inherits the global config.
**Controllers** — Admin/Settings/AiConfigurationController (global CRUD + driver list + test connection), Company/Settings/CompanyAiConfigurationController (per-company override + test), Setup/AiConfigurationController (installer wizard step, skippable with explicit ai_enabled=NO). API key is always masked as '********' in GET responses — the frontend submits the placeholder back on save and the backend preserves the stored value.
**Installer wizard** — new optional step 7 'AI' between Mail and Account. Default OFF with a Skip button. MailView.vue now routes to installation.ai instead of installation.account; installation.ai then routes to installation.account. Step order comment updated in routes.ts.
**Admin + Company settings pages** — AdminAiConfigView (no toggle, always global) and AiConfigView (with use_custom_ai_config BaseSwitchSection that auto-saves OFF). Both share AiConfigurationForm which renders the driver selector, API key input with show/hide, driver-specific config_fields (base_url for OpenRouter), and per-role enable toggles with free-text model inputs backed by a datalist of suggested models from driver metadata.
**Bootstrap endpoint** — adds an ai block to the response: { enabled, chat_enabled, text_generation_enabled }. All three are booleans resolved through AiConfigurationService::resolveForCompany(). Never leaks the API key. Frontend feature flags read from bootstrapData.ai to decide whether to show Phase 2/3 UI.
**Bouncer ability** 'manage ai config' added to SettingsPolicy, gated on isSuperAdmin() (same pattern as manage email config, manage pdf config).
**Tests** (22 new) — Unit: AiDriverFactory resolves built-in + Registry-contributed drivers, rejects unknown, merges availableDrivers. AiConfigurationService: encryption round-trip, resolution order (3 cases: global off, inherit global, override with company key, override with opt-out), makeDriver null/instance cases, listDrivers metadata. Feature: admin save + read with api key masking, preserve-on-placeholder behavior, company toggle ON/OFF semantics, bootstrap ai flags reflect resolution, company opt-out path.
372 tests pass (was 350, +22). Pint clean. npm run build clean. Phase 2 (chat assistant + tool calling) and Phase 3 (WYSIWYG text generation popup) are separate follow-up commits — this one is the foundation only.
Two plural outliers were the only directories in Services/ and Support/ that didn't follow the singular naming convention we normalized in commit 947d00a9 (Documents -> Document).
**Integrations/ExchangeRate/ -> ExchangeRate/.** The Integrations/ umbrella was both plural AND introduced an extra layer of nesting no other Support subdir had (Pdf/, Hashids/, Module/, Update/ are all one level deep). Dropping the umbrella fixes both problems in one move and matches the existing shape. When AI providers eventually land, they follow the same pattern as Support/Pdf/: a sibling subdir at Support/Ai/, not buried under an umbrella.
**Formatters/ -> Formatting/.** Formatter (singular noun) would have been awkward; Formatting (gerund describing the capability) reads naturally as a namespace segment. The subdir holds DateFormatter, TimeFormatter, TimeZones — classes whose common thread is 'things that do formatting', which the gerund captures better than either the singular or plural noun form.
10 files renamed, 4 consumers updated (DriverRegistryProvider, ExchangeRateProviderService, FormatsController, ExchangeRateDriverFactoryTest). 350 tests pass, Pint clean.
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.
Finishes the Support/ consolidation pass: the three remaining root-level files get grouped into purpose-named subdirs, matching the shape the Pdf/, Hashids/, Update/, and Module/ subdirs took in the earlier sweep.
- BouncerDefaultScope → Support/Bouncer/ (Bouncer-specific authorization scope)
- CustomPathGenerator → Support/Media/ (Spatie MediaLibrary path generator — media config references it from config/media-library.php)
- InstallWizardAuth → Support/Setup/ (folded into the existing Setup/ subdir alongside EnvironmentManager, FilePermissionChecker, InstallUtils, RequirementsChecker — it's install-wizard-flow state)
4 consumer files updated (AppServiceProvider, LoginController, UseInstallWizardTokenAuth middleware, config/media-library.php). app/Support/ root is now completely empty of standalone PHP files except helpers.php.
ModuleInstaller has the same shape as Updater (moved in 7cf72b9f): every method is public static, no constructor, no DI, no instance state. It orchestrates marketplace operations — fetch catalog, download zip, verify checksum, unzip, copy files, run module:migrate/module:enable, dispatch install/enable events — but the orchestration itself is stateless procedural plumbing.
Emitting events and writing to the Module eloquent model doesn't make it a service; plenty of static helpers touch models. The distinguishing factor is stateless-procedural vs DI-injected-workflow, and this is clearly the former.
4 consumers updated: ModulesController, ModuleInstallationController, InstallModuleCommand, and a doc comment in config/invoiceshelf.php. 350 tests still pass.
This leaves app/Services/ with no single-file driver-less subdirs except Mail/Module/Pdf/Storage which have multiple files each. The Module/ subdir in Services is now deleted entirely — the marketplace installer moved out and there were no other files in there.
Updater is a pure static procedural class — all eight public methods (checkForUpdate, download, unzip, copyFiles, deleteFiles, cleanStaleFiles, migrateUpdate, finishUpdate) are static, there's no constructor, no DI, no instance state. It's stateless self-update plumbing, same character as the Setup/ helpers that moved to Support/ in commit 6d1816bd.
Moving it out of Services/ leaves Services/ exclusively for DI-injected classes with real business logic, which is the contract the reorg was aiming for. Update/ now lives next to Setup/ in Support/ where the other install/upgrade-time utilities live.
Only 3 consumers needed touching: UpdateController, UpdateCommand, and a reference in config/invoiceshelf.php's comment. 350 tests still pass.
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.
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.
