3. Transaction Workflow
Owner: WorkspaceService owns and controls the active database transaction lifecycle. No nested transactions or SQL is present in the service class.
Flow:
Service initiates a single database connection.
Runs $db->beginTransaction().
Executes all insertions sequentially.
Commits the transaction if all insertions complete without throwing throwables.
4. Provisioning Workflow
Provisioning is executed in the following atomic order (wrapped entirely in the database transaction):

Slug Check: Verifies if the slug is unique via WorkspaceModel::slugExists(). Throws a \RuntimeException if a duplicate exists.
Workspace Record: Inserts a new row in the workspaces table with a default status of 'provisioned'.
Couple Account: Generates a secure random 12-character hex temporary password, hashes it using password_hash(), and inserts a new row in the users table linked to the newly created workspace_id (Role ID 2).
Retention Policy: Maps Plan ID (1 for Starter, 2 for Professional) to active/archived default durations (180/365 or 365/730 days) and inserts a new row in the retention_policies table.
Invitation Record: Inserts a draft invitation record pinned to Theme Version 1 (Klasik Putih v1.0).
Default Invitation Sections: Loops and inserts 8 default configuration sections (hero, story, gallery, venue, rsvp, wishes, gift, music) with visibility values.
Default Message Templates: Inserts default template wording for invitation, H-1 reminder, and wedding day reminder categories.
Printer Configuration: Inserts a default row for check-in print settings.
Audit Logging: Inserts a transaction audit record recording the action, actor, target entity, and safe states (excludes credentials/passwords).
5. Rollback Strategy
Any exception or error during execution triggers the catch (\Throwable $e) block in WorkspaceService.
The service calls $db->rollBack() to undo all database updates, ensuring zero orphaned records or half-provisioned configurations in the tables.
The exception is then rethrown for the thin controller to handle, translate to user-friendly messages, and redirect back to the form with old inputs.
6. Audit Strategy
An entry is written to the audit_logs table under action_type = 'workspace.provisioned' and action_category = 'system'.
Records the IP address and the ID/name of the Super Admin who performed the action.
Stores the configured settings in the after_state JSON block.
Secrets Protection: The generated plain text password and the hashed password are explicitly excluded from the audit log state, protecting user secrets.

Walkthrough
The Workspace Provisioning Business Logic (WS-001B) task is fully completed, tested, and automatically approved.

The transactional provisioning engine is integrated with the view form, and all tests verify correctness.

I am standing by for the next task description (e.g. WS-002 Workspace Setup Checklist) to proceed!
