The audio I heard seems to show the firetruck asking if the runway is clear to cross, the controller responding in the affirmative, the firetruck confirming the affirmative, and then 7 seconds later, the controller saying STOP STOP STOP.

It seems like less than 2 seconds from declaring intent to cross until they are told not to cross.

The runway entrance lights look red to me which is also a huge warning flag.

From the description:

I think the gaps between transmissions have been trimmed, too; this isn't matching other versions of the ATC audio, such as [VASAviation's][1].

IANA-ATC, but presumably in an emergency, you're permitted to obtain clearance from ATC to enter an active runaway, to get to the emergency. (Which they did, and got, but which ATC later effectively revokes with the command to stop, prior to the accident. Whether ATC should have granted the clearance, well, I'll wait for the NTSB report there.)

It’s supposed to be “permission to enter runway = obtained clearance && stop bars not red”. Pilots would know this; ground vehicles often do goofy stuff and it’s difficult to train them to follow procedures exactly while they have “we are responding to an emergency” in their head.
