## M0 — Project bootstrap (repo readiness)
* Tasks:
  - [x] Finalize `composer.json` (namespaces, scripts, suggests) and `LICENSE`.
  - [x] Add `.editorconfig`, `.gitattributes`, `.gitignore`, example `.env.example`.
  - [x] Set up CI (lint, static analysis, unit tests) and basic build badge.
* Acceptance:
  - [x] Fresh clone installs (without running suggested packages) and passes linters/analysis/tests.

[↑ Back to Top](#table-of-contents)
## M1 — Core HTTP kernel and routing
* Tasks:
  - [x] Implement the HTTP kernel: `PSR-15` pipeline via `Relay`.
  - [x] Wire `nyholm/psr7(-server)` factories and server request creation.
  - [x] Integrate `nikic/fast-route` with a RouteCollector and dispatcher.
  - [x] Define route → controller resolution (invokable controllers).
  - [x] Add minimal app bootstrap (front controller) and DI container wiring (`PHP-DI`).
  - [x] Addendum: Route groups (prefix only) via `Router::group()`
* Acceptance:
  - [x] Sample route returning a JSON 200 via controller.
  - [x] Controllers are invokable (`__invoke(Request)`), one route per controller.
  - [x] Route groups (prefix only) work and are tested.

[↑ Back to Top](#table-of-contents)
## M2 — Configuration and environment
* Tasks:
  - [x] Load `.env` via `vlucas/phpdotenv` and expose `Phred\Support\Config`.
  - [x] Define configuration precedence and document keys (e.g., `API_FORMAT`, `APP_ENV`, `APP_DEBUG`).
* Acceptance:
  - [x] App reads config from `.env`; unit test demonstrates override behavior.

[↑ Back to Top](#table-of-contents)
## M3 — API formats and content negotiation
* Tasks:
  - [x] Finalize `ContentNegotiationMiddleware` using `.env` and `Accept` header.
  - [x] Bind `ApiResponseFactoryInterface` to `RestResponseFactory` or `JsonApiResponseFactory` based on format.
  - [x] Provide developer‑facing helpers for common responses (`ok`, `created`, `error`).
* Acceptance:
  - [x] Demo endpoints respond correctly as REST or JSON:API depending on `API_FORMAT` and `Accept`.

[↑ Back to Top](#table-of-contents)
## M4 — Error handling and problem details
* Tasks:
  - [x] Finalize `ProblemDetailsMiddleware` with RFC7807 (REST) and JSON:API error documents.
  - [x] Integrate `filp/whoops` for dev mode (`APP_DEBUG=true`).
  - [x] Map common exceptions to HTTP status codes; include correlation/request IDs in responses/logs.
* Acceptance:
  - [x] Throwing an exception yields a standards‑compliant error response; debug mode shows Whoops page.

[↑ Back to Top](#table-of-contents)
## M5 — Dependency Injection and Service Providers
* Tasks:
  - [x] Define Service Provider interface and lifecycle (register, boot).
  - [x] Module discovery loads providers in order (core → app → module).
  - [x] Add examples for registering controllers, services, config, and routes via providers.
  - [x] Define contracts: `Template\Contracts\RendererInterface`, `Orm\Contracts\*`, `Flags\Contracts\FeatureFlagClientInterface`, `Testing\Contracts\TestRunnerInterface`.
  - [x] Define config/env keys for driver selection (e.g., `TEMPLATE_DRIVER`, `ORM_DRIVER`, `FLAGS_DRIVER`, `TEST_RUNNER`).
  - [x] Provide “default adapter” Service Providers for the shipped packages and document swap procedure.
* Acceptance:
  - [x] Providers can contribute bindings and routes; order is deterministic and tested.
  - [x] Drivers can be switched via `.env`/config without changing controllers/services; example provider route covered by tests.

[↑ Back to Top](#table-of-contents)
## M6 — MVC: Controllers, Views, Templates
* Tasks:
  - [x] Controller base class and conventions (request/response helpers).
  - [x] View layer (data preparation) with `getphred/eyrie` template engine integration.
  - [x] Template rendering helper: `$this->render(<template>, <data>)`.
* Acceptance:
  - [x] Example page rendered through View → Template; API coexists with full‑site rendering.
  - [x] Rendering works via RendererInterface and can be swapped (e.g., Eyrie → Twig demo) with only configuration/provider changes.

[↑ Back to Top](#table-of-contents)
## M7 — Modules (Django‑style app structure)
* Tasks:
  - [x] Define module filesystem layout (Nested Controllers/Views/Services/Models/Templates/Routes/Tests).
  - [x] Module loader: auto‑register providers, routes, templates.
  - [x] Namespacing and autoload guidance.
  - [x] Core CLI: add `create:module <name>` command to scaffold a module with nested resources.
  - [x] ORM‑agnostic module layout (to support Pairity DAO/DTO and Eloquent Active Record):
    - [x] `Modules/<X>/Models/` — domain models (pure PHP, ORM‑neutral)
    - [x] `Modules/<X>/Repositories/` — repository interfaces (DI targets for services)
    - [x] `Modules/<X>/Persistence/Pairity/` — DAOs, DTOs, mappers, repository implementations
    - [x] `Modules/<X>/Persistence/Eloquent/` — Eloquent models, scopes, repository implementations
    - [x] `Modules/<X>/Database/Migrations/*` — canonical migrations for the module (no duplication per driver)
* Acceptance:
  - [x] Creating a module with the CLI makes it discoverable; routes/templates work without manual wiring.
  - [x] Switching `ORM_DRIVER` between `pairity` and `eloquent` requires no changes to services/controllers; providers bind repository interfaces to driver implementations.

[↑ Back to Top](#table-of-contents)
## M8 — Database access, migrations, and seeds
* Tasks:
  - [x] Integrate `getphred/pairity` for ORM/migrations/seeds.
  - [x] Define config (`DB_*`), migration paths (app and modules), and seeder conventions.
  - [x] CLI commands: `migrate`, `migration:rollback`, `seed`, `seed:rollback`.
  - [x] All persistence usage in examples goes through Orm contracts; can be swapped (Pairity → Doctrine adapter demo optional).
  - [x] Add `register:orm <driver>` command:
    - [x] Verify or guide installation of the ORM driver package.
    - [x] Update `.env` (`ORM_DRIVER=<driver>`) safely.
    - [x] Create `modules/*/Persistence/<Driver>/` directories for existing modules.
* Acceptance:
  - [x] Running migrations modifies a test database; seeds populate sample data; CRUD demo works.
  - [x] All persistence usage in examples goes through Orm contracts; can be swapped (Pairity → Doctrine adapter demo optional).

  - [x] Utility commands: `test[:<module>]`, `run`, `db:backup`, `db:restore`.
