Chilled-Water Valve Override
Critical Room 204 · AHU-2 · CHWV-204
A BAS operator intends to override a chilled-water valve from 35% to 100% after a complaint that a critical room is warming. The demonstration preserves the route from observed condition to verified outcome.

Authentication alone was not enough. The route lacked a reason, duration, release condition, and post-check window. Without those objects, the proposed override was not execution-ready.
The correction added bounded duration, safe limits, automatic release, and an outcome check without replacing the original route history.
The record shows the condition, evidence, authority, binding, exact commit, simulated command, release, outcome, unresolved limitations, and proof boundary.
