One email, always. Every machine due inside the window is batched into a single message per recipient — even when the due dates are days apart.

Open log

Delivery
Emails are queued, retried once on failure and surfaced here. Free hosting cannot run cron — the scheduler is triggered by the first request after the window.

Upload rules

Max file size

Applies to documents and service photos.

Storage used

Allowed file types

PDF JPG / PNG / HEIC DOCX XLSX TXT / CSV ZIP EXE (blocked)

Document rules

Only a name is entered by the uploader. Files are never versioned: removing a document deletes it permanently, and the audit log records who removed it.

Zip archives
Allowed, stored as opaque binaries, download-only. Never extracted server-side.

Serving
Signed, short-lived URLs. Nothing is rendered from the application origin, so an uploaded HTML or SVG cannot execute.

Impersonation

Session limit

Idle session timeout

Impersonation shows a banner, is time-boxed, and writes two audit events (start and end). Every action inside it is attributed to the admin.

Audit

Audit retention

Record old values

Every create, update and delete is logged, including failed logins, downloads, document removals, role changes and scheduled jobs. Audit rows are append-only; no user can edit or delete them.

Audit coverage

Write paths 18 Covered 18 Gaps 0

A mutation without an event is treated as a defect.

Managers see reports, not the audit stream. Department users never see cost, through any route including audit exports.

Jobs are idempotent: the same machine and window never produce two emails.
