Register 14 · Time & cadence.

twelve marks · when measurement happens · same construction · 200×200 · integer geometry · currentColor + brass-deep · 12 marks · one of the 17 registers on the Backstaff.

This register is one face of the Backstaff evidence system — the held instrument that holds the measurement engine, maps compliance controls, and engraves every evidence record into a register of record. The full reference library lives at /corpus; the alphabetical view at /corpus/glossary; the operator view at /corpus/switchboard.

API ·

When a regulator asks for proof, hand over records — not assurances.

record the duty · seal the receipt · verify offline

Planisphere records each duty event — an output marked, a disclosure shown, a review made — and seals it into a receipt that verifies offline against our published keys. You send hashes, never content. A record is evidence a third party can check; it is not a certification and not a legal determination.
