# CD_READY Semantics Correction

## Corrected Project Rule

`CD_READY` represents media presence/readiness. It is independent of Xbox
authentication and drive unlock state.

A locked Xbox disc can therefore assert `CD_READY`; authorization controls the
accessible media view, not the presence signal supplied to the SMC.

## Superseded Wording

The earlier note and Batch-05 review used the wording “disc inserted, spun up,
and authorized.” The authorization requirement was incorrect and is
superseded by this correction.

## Retained Electrical Rule

The active-low polarity remains valid: the signal is asserted at 0 V and
inactive at 3.3 V.
