Non-receipt may indicate routing, endpoint, or configuration errors. It may also be perception caused by delay.

Why further debugging often fails

Without delivery evidence, guessing is ineffective.

Responsibility boundary

Delivery proof is owned by the sender platform.

What evidence would change this verdict

• Sender-side delivery logs confirming failure

Deterministic verification

Final decision

CONDITIONAL.
