What This Package Adds

PublishingStudio is Capell’s premium editorial timeline package. It brings the publishing loop into one workflow: preview, compare, approve, schedule, publish, and rollback content changes while preserving a readable history of what happened and why.

Draft publishing-studio for safe copy-on-write editing.
Signed live preview links with expiry, revocation, access counts, and a frontend preview banner.
Compare, diff, dry-run validation, field comments, review assignments, publish readiness checks, URL-collision checks, and stale workspace warnings.
Release Workspaces for grouped editorial releases that move coordinated content and package-owned draftable changes live atomically.
Approval history for submit, approve, reject, and request-changes decisions.
Scheduled publishing with release windows, unpublish dates, embargo windows, review reminders, immediate publishing, version history, rollback, and entity restore.
Activity timeline, stale drafts, Migration Assistant import adapters, load-test fixtures, and prune commands for editorial and operational audit trails.

Developer Notes

Adds copy-on-write, draftable model support, workspace events, review policies, preview signing, and page resource extenders without moving domain logic into Filament pages.

PublishingStudioServiceProvider, AdminServiceProvider, ConsoleServiceProvider register package surfaces.
Routes include capell/preview/exit.
Migrations create publishing-studio, versions, preview links, approvals, field comments, review assignments, and workspace columns on core/external tables.
Events track state changes and version rollback.
Publish checks include accessibility, broken links, missing alt text, SEO meta, stale workspace state, URL collisions, and release-window rules.

Operational Notes

Gives editorial teams a Statamic-style content history feel while remaining a separate premium Capell package. Editors can move from draft to preview, review, schedule, publish, and restore without losing the context behind each decision.

Adds workspace and versioning tables.
Adds workspace_id columns to core and external tables.
Adds admin resources/pages/widgets and frontend preview route.
Adds middleware to resolve workspace context.
Adds commands for install, load testing, and pruning abandoned publishing-studio.
Adds Migration Assistant adapters so page imports can stage content into workspaces when import workflows are enabled.

Data And Retention

publishing-studio stores uuid, slug, status, base version, cloned-from workspace, submitted/approved/publish timestamps, and kind/status metadata.
versions stores uuid, number, live flag, manifest, source workspace, and rollback link.
preview_links, workspace_approvals, workspace_review_assignments, and workspace_field_comments support preview, compare, comments, reviewer assignment, approval, and activity history.
Core tables receive workspace_id columns.

Screenshot Plan

Editorial timeline dashboard.
Live preview, preview link management, and preview banner.
Compare, dry-run validation, and publish readiness panel.
Approval history, reviewer assignments, and field comments.
Scheduled publishing queue with embargo, unpublish, and review-reminder metadata.
Stale drafts, recovery imports, activity history, and audit trail.
Rollback, entity restore, and version history flow.

Screenshots

Publishing workflow dashboard

Preview link management

Workspace compare readiness

Scheduled publishing

Stale drafts

Rollback restore from the pages table

The live preview, preview banner, recovery import, and activity history screenshots need seeded workspace/import data before they should be published.

Pitfalls

Models participating in draft/publish must implement Draftable and be registered.
Run migrations in order before using copy-on-write.
Publish checks, stale workspace analysis, URL collisions, and release windows can block publishing.
Preview links need expiry, revocation, and access-count review.
Schedule release windows, unpublish dates, embargo rules, and review reminders must match site operations.
Recovery Center page import screens are owned by Migration Assistant; Publishing Studio contributes workspace target, context, and collision adapters.

Verification

Run vendor/bin/pest packages/publishing-studio/tests when package tests exist.
Run the relevant host-app migration or package install flow in a disposable database.
Open the listed admin or frontend surface and compare it with the screenshot plan.
