A standard for measuring how richly a system responds when it is perturbed, and a register of every reading taken under it, failures included.
Every issued reading, on the brain it was taken from, lit by its value. The cortex surface is measured anatomy; where a reading sits on it is schematic, because no deposit publishes electrode positions. Open the atlas to spin it, choose a state and watch a perturbation travel, or fail to.The object of measurement. A system is perturbed at time zero; its response across the window is compared with its own baseline. Windows shown are the standard's TMS-EEG parameter set.
What a reading is
A reading is not a number. It is a record with a number in it: the value, its interval, the scale it belongs to, how it was recorded, the floor the same recording returns when nothing was done, and every condition of the standard it meets or fails. The reference computation is the state-transition perturbational complexity index, PCIST, specified in full so it can be reimplemented from the text alone.
Readings on different scales are never mixed. Readings taken at different grain, in space or in time, are never compared without saying so.
A reading never states whether anything is, or is not, conscious. Not for a person, an animal, a tissue or a machine. Not now, not later.
Where the register stands
Every reading is published with its failures on its face, and the conformance count is published at zero because that is the only way its rise will mean anything.

The documents
Everything the register rests on is published here in full, and every figure on these pages is rendered from the file it comes from.
AtlasEvery issued reading placed on the brain it was taken from, lit by its value. Choose a state and watch a perturbation travel, or fail to.
MethodThe standard itself: what a reading is, how it is computed, and the twelve conformance conditions.
PCIST-1.0 annexThe reference computation, specified so it can be reimplemented from the text alone.
RegisterEvery reading, with the conditions it fails, rendered from the register file.
Conformance vectorsEight diagnostic vectors and an offline verifier for any implementation of the annex.
InstructionHow a reading is recorded, domain by domain, so two raters produce the same record.
GovernanceWho holds the standard and the register, and the separation committed to.
Open call: condition 9The invitation to write an independent implementation, the one condition that cannot be closed from inside.
ResultsEvery result the method rests on, published whether it helped or not.
