Bug-out Shelter #7 – Silent Defense

Mission

The diversion has worked — at least for now — and the raiders are moving away toward the decoy.
But the threat remains imminent: they will find their way back, and any compromise of internal silence will be enough to bring them straight to you.

Now Promèthes must evolve from a vulnerable refuge into a discreet fortress.
No noise, no unnecessary emissions, with defenses capable of reacting instantly if the enemy brings their observation zone closer.
You must plan and schedule silent defensive measures: position equipment for ambush, and organize human rotations that minimize noisy movements.

Act quickly and precisely: every placement, every intervention window must preserve the shelter’s invisibility while maximizing its ability to respond.
It is a game of shadow and patience — and failure will mean that Promèthes will not remain hidden for long.

Rules

You have at your disposal 4 pieces of information:

• windows: possible intervention windows, composed of a start timestamp and an end timestamp (separated by an “_”)
• detections: moments during which noise is detected. You have the timestamp and the detected noise intensity (separated by “:”)
• treshold: the maximum possible noise intensity
• latency: the minimum time between 2 intervention windows (between the end of window N and the start of window N+1)

You must first look for the windows whose total intensity does not exceed the threshold.
The total intensity is the sum of the detected intensities between the start and the end of the window.

Then, it is considered that the first window is always selected (the first being the one that starts the earliest).
We will then try to keep all the windows, in chronological order, as long as they respect the latency criterion.

You must return the number of windows kept and the sum of the total intensities of the windows kept, separated by a ":".

Example:

10:223 or 9:315
