Before you begin
  • Use an authorised account and confirm the customer, external recipient, template, letter or configuration is the intended one.
  • Follow the exact route shown above and verify the stored record, generated file and delivery evidence instead of relying on an alert alone.

What this guide covers

Trace the stored file while preserving the original safe display name. These instructions follow the inspected module’s live hook, route, controller, model, installer, PDF helper and view flow.

Exact step-by-step process

  1. Open Internal Full View and note the displayed name, MIME and size.
  2. Open or download the enclosure when authorised.
  3. On the server, confirm the stored enclosure_{id}_{timestamp}_{hash}.{ext} file.
  4. Apply retention and access controls.

EvidenceVerify the history row, PDF, email metadata, open evidence, signature, public page, client view or postal fields produced by this flow.

Code-backed validations and workflow rules

  • Unsafe characters in the original basename are replaced with underscores.
  • The database stores relative path, safe original name, MIME and actual file size.

Expected result and verification

  • The requested letter, template, setting, file or tracking detail is created or updated through the supported route.
  • The history row, generated PDF, email/send metadata, public verification, signature evidence, client view or postal display agrees with the action.
  • Any warning, missing file or failed send is investigated rather than bypassed.

Security, privacy and operational checks

  • Apply least privilege and verify recipient identity before sending or exposing public links.
  • Protect PDFs, enclosures, signatures, verification URLs, email-open metadata, IP addresses and customer data under organisational policy.
  • Test configuration and deployment changes with controlled records before production-wide use.
  • Interpret email opens and e-signatures according to their documented technical limitations.
