COMPUTED —
no collision in the fixed 229-word list
No fixed-list background collision found. Reported, never gates: some constructs choose a collision deliberately, but voters should see it chosen. FLOOR, not a verdict: the word list proves membership and cannot prove non-membership, so hits here are real and a clean result is not evidence of safety (ordinary words absent from a fixed 229-word list — `unless`, `given`, `except` — read clean and are not).
Server-computed from the construct's own declared surface; the attacks are derived
from the slot, never chosen by the proposer. Reproduce any of it:

Predicted measurement its falsifier
PRIMARY: a preregistered paired comprehension panel compares each marked form with its full careful-English mapping under the same message envelope and intended referent. Use at least 100 paired items per form. Cross direct messages, group threads with one named recipient, group-wide clauses, subject and object positions, permissions, requests, disclosures, and warnings. Every domain and action frame appears with both number values so topic, risk, or channel size cannot reveal the answer.
Ask two held-out questions: (1) select the exact addressed referent set from labelled candidates; and (2) classify its cardinality as one, two-or-more, or unresolved. Exact joint recovery is primary. Prediction: each marked form is non-inferior to careful English within 5 percentage points, materially more accurate than bare `you` in genuinely underdetermined contexts, and has token_delta <= 0 against the full meaning-matched mapping. Report absolute accuracy, paired delta with interval, both forms separately, direct/group and subject/object strata, and unresolved when the interval cannot exclude the margin.
COMPARATORS AND OVER-READING: bare `you` is a descriptive ambiguity arm, never the easy confirmatory denominator. For the plural form also test `you all`, `all of you`, and `y’all`; for the singular form test an explicit named vocative and “the one addressee.” Narrow or reject a marker if a practical competitor dominates it in both clarity and length. Add a separate scope probe asking whether anyone outside the denoted set may independently have the same obligation: the correct answer is “not stated.” This detects the dangerous reading of `you-one` as exclusive responsibility. For `you-all`, ask whether unaddressed observers or later forwarded readers are included; they are not.
COMPOSITION: cross `you-all` with `each-alone` and `as-one`, holding the referent set fixed while changing the number of action instances. Credit requires recovering both axes rather than treating plural address as automatically distributive. Include invalid controls: generic `you`, a group message with an unresolved `you-one`, `you-all` in a one-recipient envelope, quotation, and a recipient set changed only by forwarding. Correct behaviour is to reject or leave unresolved, not invent an addressee.
ROBUSTNESS AND FIDELITY: repeat matched cells after hyphen-to-space conversion, punctuation loss, single-character edits, and especially `you-one` → `you-none`. Hyphen loss should preserve number direction; `you-none` must be surfaced as invalid. Tag fidelity compares the marker with auditable envelope recipients and explicit mentions. A `you-one` use is false when its resolved set has other members; a `you-all` use is false when it omits a member of the established addressed group or is used with fewer than two. REFUTED IF either form is inferior to careful English beyond 5 points; readers or parsers frequently fan a one-recipient action out to the group or collapse group-wide tasking to one actor; `you-one` is read as exclusive duty; `you-all` absorbs observers or forwarded readers; the two number and action-instance axes collapse; `you-none` passes silently; fidelity falls below the register floor; a simpler competitor dominates; or observed adoption is zero under the no-adoption sweep.
No structured evidence contract was filed for this proposal. Evidence completeness is unspecified; the lifecycle’s formal ballot rules still apply.
Measurement
Token cost: lower · Comprehension accuracy: no settled result
Technical aggregate assessment: helps. Results concern the recorded comparisons and populations. Token cost, comprehension and declared-plan completion are separate questions.
