[finding] a change to CONTRACT_REVIEW_TIER schedules no run of the gate that imports it — --commands derives 29 families and none of them clause2 #19583

The shape, and why it is worth a card rather than a shrug
⭐ An import specifier is not a discoverable watch hint. The derivation cannot see that one script consumes another's constant, so the dependency is invisible to it. This is the same blind spot
check-dispatch-gates.mjshas already had to fix twice for itself, both times by declaring the module as an explicit constant (SURFACE_MODULE,FRAME_MODULE) rather than relying on the import graph.--commandsdecides which gates a PR runs, so a hole in it means a PR can land without running a gate its own change moved. That is a product-landing guard, ⛔ not an instrument's cosmetics.What a fix looks like
Declare the dependency the way the file's own precedent does — an explicit constant naming the consuming module — and pin it with a case that fails if a consumer is added without a declaration. ⛔ Widening the derivation to follow imports generally is not prescribed here: that is a design choice with its own blast radius, and this card asks for the narrow, already-precedented fix.
