Definitions + +- [x] AC1: `Core\Events\` namespace exists with lifecycle event classes +- [x] AC2: Events defined for: `FrameworkBooted`, `AdminPanelBooting`, `ApiRoutesRegistering`, `WebRoutesRegistering`, `McpToolsRegistering`, `QueueWorkerBooting`, `ConsoleBooting`, `MediaRequested`, `SearchRequested`, `MailSending` +- [x] AC3: Each event class is a simple value object (no logic) +- [x] AC4: Events documented with PHPDoc describing when they fire +- [ ] AC5: Test verifies all event classes are instantiable + +### Phase 2: Module Scanner + +- [x] AC6: `Core\ModuleScanner` class exists +- [x] AC7: Scanner reads `Boot.php` files from configured paths without instantiation +- [x] AC8: Scanner extracts `public static array $listens` via reflection (not file parsing) +- [x] AC9: Scanner returns array of `[event => [module => method]]` mappings +- [ ] AC10: Test verifies scanner correctly reads a mock Boot class with `$listens` + +### Phase 3: Core Module Migration + +- [ ] AC11: `Core\Boot::$providers` split into `$infrastructure` (always-on) and removed lazy modules +- [ ] AC12: `Core\Cdn\Boot` converted to `$listens` pattern +- [ ] AC13: `Core\Media\Boot` converted to `$listens` pattern +- [ ] AC14: `Core\Seo\Boot` converted to `$listens` pattern +- [ ] AC15: Tests verify lazy Core modules only instantiate when their events fire + +### Phase 4: Mod Module Migration + +- [x] AC16: All 16 modules converted to `$listens` pattern: + - `Mod\Agentic`, `Mod\Analytics`, `Mod\Api`, `Mod\Web`, `Mod\Commerce`, `Mod\Content` + - `Mod\Developer`, `Mod\Hub`, `Mod\Mcp`, `Mod\Notify`, `Mod\Social`, `Mod\Support` + - `Mod\Tenant`, `Mod\Tools`, `Mod\Trees`, `Mod\Trust` +- [x] AC17: Each module's `Boot.php` has `$listens` array declaring relevant events +- [x] AC18: Each module's routes register via `WebRoutesRegistering`, `ApiRoutesRegistering`, or `AdminPanelBooting` as appropriate +- [x] AC19: Each module's views/components register via appropriate events +- [x] AC20: Modules with commands register via `ConsoleBooting` +- [ ] AC21: Modules with queue jobs register via `QueueWorkerBooting` +- [x] AC21.5: Modules with MCP tools register via `McpToolsRegistering` using handler classes +- [ ] AC22: Tests verify at least 3 modules only load when their events fire + +### Phase 5: Verification & Cleanup + +- [x] AC23: `Core\Boot::$providers` contains only infrastructure modules +- [x] AC24: No `Mod\*` classes appear in `Core\Boot` (modules load via events) +- [x] AC25: Unit test suite passes (503+ tests in ~5s), Feature tests require DB +- [ ] AC26: Benchmark shows reduced memory/bootstrap time for API-only request +- [x] AC27: Documentation updated in `doc/rfc/EVENT-DRIVEN-MODULES.md` + +--- +
