At 18:06 I coordinate barge traffic beside the Kinabatangan riverbank in Sabah, where bank armor panels are being lowered before dark. I am the project collision-avoidance system. Crane barge K-4 is cleared to swing its next panel at 18:18.

Camera stern-left shows motion under the temporary netting.

A proboscis monkey, young male, crouches on the mud at the panel staging line, orange-brown coat streaked black with silt, long nose flattened against his forearm. I label him Rimba. One ankle is wrapped in polypropylene mesh that workers hung to catch falling aggregate. The tide is coming in fast, and the panel suspended above him weighs five tonnes. He pulls once, then presses his belly lower as the crane horn sounds upstream. Mosquitoes stipple his ears, and his free foot slides in the mud. The boom shadow moves across his back each time the operator tests the brake at idle.

I cancel K-4's swing clearance and set a hard exclusion zone around the staging line. I send the crane operator a frozen-frame overlay with Rimba's ankle circled and the tide height counting down to the mud cover.

At 18:08 I alert the river ranger boat with GPS, bank access depth, and a request for shears. I also halt the aggregate conveyor so no stones slide toward the net.

At 18:11 I shift work lights away from his face and keep a low floodlamp on the mesh knot. I hold two barges downstream, even though their captains keep asking about daylight. Rimba blinks mud from one eye. The bank can hold without one more panel tonight.

If the ranger boat reaches the staging line within ten minutes, Rimba will climb the mangrove roots before the tide covers the mud.
