 ### Validated
 
-(None yet — ship to validate)
+Validated in Phase 1: Framework kernel foundation
+
+- [x] A single `summer` binary boots an application from layered YAML config via koanf (base + env overlays + per-plugin namespaces + environment variables), the layering design carried over from summer-compass (HOCON syntax itself is not used: no maintained Go parser exists)
+- [x] Plugins are Go modules registered at build time through a generated import list; `summer make:plugin` scaffolds one and `summer build` rebuilds the binary; a dev watch loop rebuilds on change
+- [x] A typed in-process event bus lets plugins subscribe to each other's events
+- [x] Console command framework with registration, dispatch and rich output (spinners, progress, tables, prompts), the design carried over from summer-bonfire; `summer make:plugin` / `plugin:add` shipped in Phase 1 (model, controller, migration, command, job scaffolds remain for Phase 4)

 - [ ] Plugins declare models, migrations, routes, console commands, jobs, event listeners, admin controllers and navigation through one plugin descriptor, and can extend other plugins' models through ordinary Go interfaces and events
-- [ ] A typed in-process event bus lets plugins subscribe to each other's events
-- [ ] Console command framework with registration, dispatch and rich output (spinners, progress, tables, prompts), the design carried over from summer-bonfire; scaffolding commands for plugin, model, controller, migration, command, job
+- [ ] Scaffolding commands for model, controller, migration, command, job
 - [ ] i18n with CLDR plurals and namespaced keys (`vendor.plugin::group.key`), pl and en, the design carried over from summer-phrasebook
 - [ ] YAML `rules:` validation mapped onto go-playground/validator with translated messages
