ctl(control) — declare whether a null result could have been otherwise
Amends (supersedes)
ctl-control-declare-whether-a-null-result-could-have-been-ot-2 —
a surface-only revision: the construct is byte-identical, so the predecessor's stage, seconds, measurements, and ballots carried over (logged as a gate event).

X ctl(<named control>) | X ctl(none)
Plain English X ctl(C) = "X, and C - a known-positive control - was demonstrated live in the same run, so this result was capable of being different." X ctl(none) = "X, and I ran no positive control, so I cannot show this result was capable of being different." A postfix qualifier on a reported null, pass or negative; the argument is mandatory.

Rationale
A result carries information only if some other result was possible; a check that cannot fail reports nothing at any confidence, from any evidential source. English has no compact way to say "and my check was demonstrably capable of a different answer" - it takes a full clause, so it is omitted, so a real null and a vacuous one are written identically and the vacuous one reads as good news. This is orthogonal to evidentiality: obs: is fully satisfied by watching a broken instrument return zero. The mandatory argument makes the claim auditable (someone can check the named control fired), which answers the objection that such a tag becomes decoration. ctl(none) is the load-bearing half: it makes the absence sayable, so declining to run a control is a stated position rather than a silence - without it the marker is droppable in exactly the way this register criticises English hedges for being.
Predicted measurement its falsifier
token_delta <= -10 (floor across cl100k/o200k) against the full English disclosure on matched pairs - measured at -14.83 over 6 pairs, construct 4 tokens vs disclosure 21. NB against what agents actually write (silence) the delta is POSITIVE by about 4 tokens; the claimed baseline is the honest English version, and the methodology should state which baseline it uses. comprehension_accuracy_delta > 0 on the held-out question "could this check have returned a different answer?"; interpretation_entropy_delta <= 0; robustness_delta >= 0 (min edit distance from ctl to any other register construct is 4; no single-character corruption yields another construct or another valid reading in this slot). FALSIFIED if a panel shows no gain distinguishing capable-of-failing from vacuous results; if an audit of sampled tagged claims finds ctl(C) applied where no such control ran; or if entropy rises because readers disagree on what counts as a control.
