QC Digital Signature Final PDF and Completion Delivery Scheduled Task

The Final PDF and Completion Delivery Scheduled Task finishes work that may still be pending after the last required signer completes a Request. QCDS creates the task with a 5-minute default cadence.

It finalizes completed PDFs, retries eligible completion failures, and processes due completed-document email delivery without changing the frozen Request snapshot or signer evidence.

What the Task Does

QCDS completion is intentionally idempotent. When every required actionable participant is complete, QCDS can generate the protected final PDF, mark the Request completed, and deliver completion messages. If a normal completion or completion email is still pending, the Scheduled Task picks up that work on a later run.

The task also processes the bounded recovery queue for Requests in completion_failed when the protected render set is ready. Recovery bookkeeping does not rewrite stored signatures, signer-field values, or the immutable Request snapshot.

Default Five-Minute Schedule

The installer creates one canonical QC Digital Signature Final PDF and Completion Delivery task with a 5-minute interval. QCDS preserves an administrator-selected schedule on update, but the task still depends on Joomla Scheduled Tasks actually being triggered.

A signer can therefore finish successfully while the Request briefly remains in a completing or recovery state until the next scheduler execution finishes the protected artifact/delivery work.

How Automatic Completion Recovery Works

QCDS caps automatic final-PDF recovery at three attempts per Request. If another attempt is available, the first retry waits about 5 minutes and the next waits about 30 minutes before the third/final automatic try. Missing legacy render metadata is treated as a preparation condition rather than consuming an attempt.

If all automatic attempts are exhausted, QCDS stops the loop. An authorized sender can use the explicit Retry Final PDF action to reset the bounded recovery sequence rather than repeatedly recreating the Request.

If Completion Appears Stuck

  1. Open System > Scheduled Tasks and confirm the Final PDF and Completion Delivery task is enabled.
  2. Review its last execution, next execution, and failure count.
  3. Confirm Joomla's scheduler runner is firing reliably; a valid task row can still be overdue on a quiet site.
  4. Open the affected Request and distinguish a PDF finalization failure from a completed-document email delivery failure.
  5. If QCDS reports that automatic recovery is exhausted, use the explicit Retry Final PDF action only after correcting the underlying PDF/render issue.

Do Not Duplicate the Task

The installer requires exactly one enabled canonical completion task and disables duplicate rows. If the task is missing or damaged, repair/reinstall the current QCDS package rather than creating competing completion workers.
