e.rule.¶

e.rule. is a match pattern, never a code. It selects every code below it, including ones minted after your handler was written.

The obstacle: A norm we enforce, neither authority nor verification.

This obstacle has no standard sub-descriptors, so every leaf under it is one a repo minted for itself.

Codes under this prefix¶

• e.rule.expired.f — The signature is past the expiry its own signer declared, so I won't accept it.
• e.rule.stale.f — The signature is outside the age limit this verifier accepts.
