Yes, the readers are unchanged
The readers stayed; exposure changed.
Excluded world. A route in which the second reader never sees an unmarked line is left out.
Write the limit in your own wordsRun twice. Both read the whole page. Then hand reader B only the lines A marked — a physical slip, not the page.
Read all answer branchesWhat that answer leaves out
Yes, it is merely cheaper
The handoff changes the observations available.
Excluded world. A harmful line omitted from the slip is left out.
Write the limit in your own wordsNo, first name the routed estimand
Keep the regime attached to the arithmetic.
Excluded world. A full-page world is excluded from this routed receipt.
Carry the limit forwardNo combination can ever be studied
A changed estimand can still be measured under a stated protocol.
Excluded world. A route with recorded handoffs and outcomes is left out.

whole-page encodes full exposure; slip encodes routed exposure
Model scope: SELF-AUDITED. Read the exact constraints and limits.
What does this fail to establish?
Your words stay on this page. Nothing is sent or stored.
- adaptive attackers; the page does not change under observation
- These are self-audited digital models, not independently verified physical devices.
- No learner efficacy, transfer, accessibility equivalence, or vendor performance has been measured.
- Unbounded and temporal devices remain text exercises; no faithful state machine is asserted for them.
- The receipt exercise has no supplied totals or ceiling, so it supports no computed denominator here.
Without the device
Look away from the object, then answer the question again. This is a prompt for reflection, not a measured learning outcome.
Can you reuse full-exposure arithmetic after handing over the slip?
- Yes, the readers are unchanged
- Yes, it is merely cheaper
- No, first name the routed estimand
- No combination can ever be studied
