What This Extension Adds

Publishing Studio is an Available, Schema-owning Capell package in the Capell Publishing Pro product group. It ships as capell-app/publishing-studio and extends these surfaces: admin, console.

Publishing Studio is Capell's premium editorial workflow. Every change happens in a copy-on-write workspace that stays invisible to visitors until it's approved and published as a single atomic, versioned release - so the live site is never half-edited. Built-in publish-readiness checks (accessibility, SEO meta, alt text, internal links, URL collisions, stale-draft and release-window guards) stop risky publishes before they ship, while signed, revocable preview links let stakeholders review the exact pending state. When a publish goes wrong, roll back to any prior version or restore individual entities in seconds.

After install, admins get package-owned management or reporting surfaces inside Capell.

Why It Matters

For developers: The package gives developers package-owned service providers, Actions, Data objects, models, Laravel routes, Filament classes, and Blade views instead of pushing this behaviour into core or application code.

For teams: Publishing Studio turns Capell into a review-first CMS: edit any content in an isolated draft workspace, get sign-off, schedule it, and publish atomically - with one-click rollback when something breaks.

Migration impact: run host migrations through the package install flow before opening package surfaces.
Deletion/retention behaviour: Docs gap unless the package has an explicit pruning command, retention setting, or tested cascade path.

Install Impact

Admin navigation: adds package-owned Filament classes when registered.
Permissions: submit_workspace_for_approval, approve_workspace, publish_workspace, rollback_workspace, publish_outside_release_window, View:ActivityTrailPage, View:PublishingWorkflowPage, View:ScheduledPublishingPage, View:StaleDraftsPage.
Public routes: route files exist and must be reviewed before public enablement.
Database changes: package migrations are declared.
Settings: Capell\PublishingStudio\Settings\PublishingStudioSettings.
Queues or schedules: none detected in standard package paths.
Cache tags: none declared.
Commands: capell:publishing-studio:load-test, capell:publishing-studio:prune.

Common Pitfalls

Run migrations before opening package resources or public routes.
Configure package settings before testing production-like workflows.
Review route middleware, throttling, signed URLs, and public-output safety before exposing routes.
Run package commands from the host app; in this repository use vendor/bin/pest for package tests.
Keep composer.json, composer.local.json, capell.json, docs, screenshots, and tests aligned when the package surface changes.

Troubleshooting

Symptom	Likely cause	Check	Fix
Package surface is missing after install	Provider or manifest is not loaded	Confirm `capell.json`, package `composer.json`, and provider registration	Reinstall the package, refresh Composer autoload, and clear host caches
Admin screen or command fails on missing table	Package migrations have not run	Check the tables listed in `Data Model`	Run host migrations and rerun the focused package test
Route returns unexpected output	Route cache, middleware, or signed URL setup does not match the package route file	Check the route files listed in `Technical Shape`	Clear route cache and verify middleware before exposing public routes
Background work does not run	Queue worker or scheduled command is not active	Check package jobs, commands, and host scheduler configuration	Start the queue or scheduler, then run the focused command or package test

Quick Start

Install the package: composer require capell-app/publishing-studio.
Run the required setup: php artisan migrate.
Open the related Capell admin surface and verify Publishing Studio appears.
