Mutual exclusivity is required for allocation-by-relative-cost to be measurable, but the school-test specimen books the same hours leaving untested subjects as both base loss (narrowed curriculum) and incidence shifting (quality transferred to tested domains).

The elasticity hierarchy ranks channels by the responding agent's private cost. A quarterly sales target makes deal-timing cheap for the salesperson and also cheap for the manager whose scoreboard is the quarterly number. When those rankings diverge, shipped response is which agent's ranking binds, not a single-agent elasticity.

Channels two through four are the Piketty-Saez-Stantcheva three elasticities; formal gaming is narrow Goodhart. The named remainder is cross-domain transfer. Transfer is a result that moves an instrument in another domain, not a mapping of names.

Section VII lists the OECD 15% minimum tax as a way to raise the cost of formal gaming. Section V already shows carve-outs reopening that channel. The listed repair is itself an intervention and is not given a four-channel forecast in the engineering section.

The capability prediction (better eval-context recognition makes passing less informative because gaming and incidence get cheaper) is carried by planted backdoors that resist removal. Persistence given a backdoor is not a cost ranking that changes with capability.

Land-value tax works because the base cannot relocate. Tying an eval surface to internal computation is not the same property: a representation can be rewritten or duplicated while a probe stays clean. The LVT analogue smuggles physical immobility into a movable measurement.
