Replace the manual `$request->route('formSubmissionActionFailure')` workaround
with type-hinted parameters. Implicit route model binding now resolves
FormSubmissionActionFailure correctly on both the platform admin route
(/admin/form-failures/{id}) and the org-scoped route
(/organisations/{organisation}/form-failures/{id}).
Root cause:
On the nested org-scoped route, Laravel's implicit binding triggers its
scoped-binding code path: for the second URL segment, it tries to resolve
the failure as a relation of the route's parent ({organisation}) by calling
`$organisation->formSubmissionActionFailures()`. Organisation has no such
relation (failures live under FormSubmission, not Organisation directly),
so the lookup silently fell through and the controller received a raw
string. PHP then raised a TypeError on the type-hinted parameter.
A second issue compounded it: with the controller method declaring
`(FormSubmissionActionFailure $formSubmissionActionFailure, ?Organisation $organisation)`
the parameter order did NOT match the URL parameter order
(/{organisation}/.../{formSubmissionActionFailure}), so Laravel's
resolveMethodDependencies — which falls back to positional binding when
parameter counts diverge — bound them to the wrong slots.
Fix:
- Register an explicit `Route::bind('formSubmissionActionFailure', ...)`
in AppServiceProvider that loads the model `withoutGlobalScopes()` and
throws ModelNotFoundException on miss. This sidesteps the scoped-binding
parent-relation lookup entirely.
- Add `->withoutScopedBindings()` to all four org-scoped routes (show,
retry, resolve, dismiss) as a belt-and-braces guarantee that Laravel
never enters the scoped-binding path for these nested routes.
- Reorder controller method signatures to put `?Organisation $organisation`
FIRST, matching URL parameter order so positional binding lands the
ULID strings on the correct method parameters.
- Drop the now-unused private `resolveFailure()` helper.
- Tenant scoping continues to be enforced by FormSubmissionActionFailurePolicy
via the failure.submission.organisation_id FK chain (RFC V3); cross-
tenant access still translates denied → 404, never 403.
Tests: all 9 controller tests pass (cross-tenant 404 contract verified for
view, dismiss, and resolve).

Two route groups: /api/v1/admin/form-failures (super_admin platform) and
/api/v1/organisations/{organisation}/form-failures (org_admin scoped).
Same controller, policy authorises via FK chain (RFC V3). Cross-tenant
access returns 404 not 403 to prevent enumeration.
Resolve takes optional note; Dismiss requires DismissalReasonType
enum with conditional note (mandatory for 'other'). Both via
FormRequest validation with explicit i18n message keys.
Implementation note: Laravel implicit model binding for nested-namespace
ULID models doesn't pick up reliably across nested route groups. Using
manual resolveFailure() helper that loads withoutGlobalScopes() (so
cross-tenant access still reaches the policy, which translates denied →
404 per V3). Policy explicitly checks soft-delete via deleted_at since
withoutGlobalScopes bypasses SoftDeletes too. Policy registered
explicitly in AppServiceProvider — auto-discovery doesn't reliably
resolve App\Models\FormBuilder\* → App\Policies\FormBuilder\*.
NOT: admin UI (session 3). Not: public form routes (no API contract
notification needed).
