Compliance by design, not by policy.
A policy can be ignored. The system cannot. Wēlr is built so compliance is the default, not something you prepare for.
Four hard constraints — never violated.
- Constraint 01
Separation of duties is enforced in code.
Creator ≠ approver. Executor ≠ approver. Checked at the model and view layer — not just documented.
- Constraint 02
Audit-log records are immutable.
Audit log models do not expose update() or delete(). No migration may add them. No view may modify audit records.
- Constraint 03
Self-approval is rejected at every layer.
Agent workflows, application code, and user-facing features. No user approves their own work — ever.
- Constraint 04
Every action is attributable.
Descriptive entries with object IDs. Traceability is never squashed out of history.
| UTC | Actor | Action | Detail | Object |
|---|---|---|---|---|
| 14:06:40Z | system — | export | Evidence package assembled from the trace below | PKG-2891 |
| 14:02:11Z | M. Reyes Service Engineer | execute | Captured cryogen pressure 0.62 psig | WO-00342818 · §05 |
| 14:01:55Z | M. Reyes Service Engineer | execute | Scanned lockout LK-7831 | WO-00342818 · §04 |
| 13:58:02Z | K. Davis Manager | approve | Rev 4.2 promoted to live — approver ≠ author | PROC-MRL-118 |
| 13:52:44Z | S. Whelan Tech Writer | blocked | Self-approval refused — author cannot approve | PROC-MRL-118 |
| 13:48:07Z | S. Whelan Tech Writer | create | Rev 4.2 drafted from source p.118 | PROC-MRL-118 |
Read it bottom-up and every constraint on the left is visible in the record: an author drafts a revision, the system refuses to let them approve their own work, a second person approves it, an engineer executes against the approved revision, and the evidence package assembles from that trace rather than being reconstructed afterwards.
A readiness view your quality team can act on before the audit.
Wēlr scores six compliance domains continuously and exports a single audit package on demand. Training, NCR, Inspection, Calibration, Procurement, Service — each with the evidence it took to earn the score, signed and locked.
Ready to stop stitching service evidence together?
If your team is juggling PDFs, support packages, work orders, customer updates, and QA evidence across five systems, Wēlr is worth a look.
