## Problem
`bun run build` failed whenever `REGISTRATION_ENABLED=false`.
`config/fortify.php` only added `Features::registration()` when the env
flag
was truthy, so with the flag off Fortify never registered the
`/register`
routes. Wayfinder only generates helpers for registered routes, so the
`register` / `register.store` helpers imported by
`resources/js/pages/auth/login.tsx`
and `resources/js/pages/auth/register.tsx` no longer resolved and the
build
broke. The build outcome depended on an env flag — not deterministic.
## Fix
Decouple *route registration* from *whether sign-ups are accepted*:
- **Always register** `Features::registration()` in
`config/fortify.php`, so the
`/register` routes (and their Wayfinder helpers) always exist and the
build is
deterministic regardless of the flag.
- Gate acceptance at **runtime** via a new
`config('auth.registration_enabled')`
value (mapped from `env('REGISTRATION_ENABLED', true)`), the single
source of truth.
- When registration is disabled:
- `GET /register` (Fortify register view) and `POST /register`
(`CreateNewUser`)
return **403**.
- Registration CTAs stay hidden via `canRegister` (login view + landing
page).
- Guests are redirected to `/login`
(`AuthEntryPointService::guestRedirectRoute`).
- With the flag enabled (the default), registration behaves exactly as
before.
## Tests
- Rewrote `tests/Feature/Auth/RegistrationDisabledTest.php` to the
runtime
mechanism: registration enabled by default, route helpers always
registered
regardless of the flag, `GET`/`POST /register` return 403 when disabled
(and no
user is created), and the landing/login CTAs hide.
- Updated the `DashboardTest` disabled-registration case to toggle
`config('auth.registration_enabled')` instead of filtering the Fortify
feature.
- Verified `bun run build` succeeds with `REGISTRATION_ENABLED=false`
and that the
`register` / `register.store` Wayfinder helpers are generated.
## Docs
- Updated `README.md` and `.env.example` to describe the 403 behavior
(routes stay
registered rather than being removed).
