}Replace a test's spec
Replaces what the spec covers and makes a new revision. An edit that changes what is played or checked clears the calibration, so the test stops gating until calibrated again. An archived test is refused (422).

What the test list calls it. Null on tests made before titles.
production: a stored call replayed. custom: written as a spec. probe: written for a brief line no call exercises; never gates.
production, custom, probe The lane a defect lives in: hearing, understanding, flow, speaking or integrations.
hearing, understanding, flow, speaking, integrations, null The caller's intent the test covers.
