3. Checklist Evaluation Workflow
Service Evaluation: WorkspaceService::getChecklist() evaluates setup checklist states. It retrieves information from the database via WorkspaceModel and maps them to the seven steps.
Flow:
Workspace Provisioned: Marked completed.
Configure Invitation: Checks if invitations.invitation_status is not 'draft'.
Select Theme: Checks if invitations.theme_version_id is assigned and greater than 0.
Add First Guest: Checks if non-deleted guest count in the guests table is greater than 0.
Configure Printer: Checks if columns in printer_configurations differ from initial defaults.
Create First Wedding Event: Checks if non-deleted wedding event count in wedding_events is greater than 0.
Ready To Send: Evaluated dynamically based on the logical AND of steps 1 through 6.
4. Progress Calculation Logic
Formula: Calculated as: $$\text{Progress} = \text{round}\left( \frac{\text{Completed Steps Count}}{7} \times 100 \right)$$
Context: Since step 7 completes automatically when steps 1-6 are finished, the progress increments in stages and reaches $100%$ when the entire checklist is unlocked.
5. Ready To Send Logic
Locking Gate: Calculated as a logical AND of steps 1 to 6.
Action: If any step from 1 to 6 is pending, step 7 is marked locked (incomplete) and ready_to_send_unlocked is set to false. Once all prerequisites are complete, step 7 automatically evaluates as completed, unlocking the invitation sending phase.
6. Security Verification
Prepared SQL: Every query in WorkspaceModel uses parameter-bound values (:workspace_id) to avoid SQL injections.
Tenant Isolation: Every database count/retrieve method filters queries using workspace_id to block cross-workspace data access or leakages.
Output Escaping: The view uses escape_html() for every dynamic variable.
