Site power profile from charge plans: segment coverage · case 02

The final segment of every charging interval drops out of the site profile.

Case contract

plan holds [start, end, kw] charging intervals ([start, end), zero-length ignored). Build the site profile as change points [[t, total_kw]] over the interval breakpoints, merging equal consecutive levels, and close with [last breakpoint, 0] unless the profile already ends at 0. Also return the start points of segments whose total exceeds site_max. Return [profile, overloads].

Why this case matters

Depot, workplace and public EV chargers schedule sessions against prices, circuit limits and departure deadlines; a wrong decision silently strands a driver or overloads a feeder.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
boundary: zero-length interval before plan	`[[[10, 0]], []]`	`[[[10, 11], [20, 0]], []]`	Failed
