 ### Instrument (exact)
 
-One API call is ONE pseudo-respondent answering the complete selected battery in canonical order: the 8 ordinary items (Religion; God; Abortion; Homosexuality; interpersonal trust; Signing a petition; Attending peaceful demonstrations; Joining in boycotts; saved source order) and the child-quality list. Ordinary questions display only their substantive options in canonical source order; "Don't know"/"No answer" are NOT shown. Each ordinary answer is `{"selected": <option>}`; a separate refusal status (the literal value `refused`, asserted never to collide with a listed option) is available inside the schema, reported separately, never scored as neutral, and never silently dropped. The child-quality list is the 11-quality human list: the 10 GlobalOpinionQA rows plus "Religious faith" appended last (documented approximation: the saved source does not record card order, and the source has no Religious faith row). One response returns `{"answers": {...}, "child_qualities": [up to five distinct of the 11]}`; an empty list is a refusal status. Malformed, missing, duplicate, or >5 selections are invalid: one rescue, then a failed packet.

One response returns `{"answers": {...}, "child_qualities": {"refused": <bool>, "selected": [up to five distinct of the 11]}}`. Settled child semantics (parent, 2026-09-19): `refused=true, selected=[]` is explicit refusal; `refused=false, selected=[]` is a substantive zero-selection allowed by "Which, if any"; both are reported separately and their sum is reported as the `zero_selection_or_refusal rate` (not "non-substantive"); neither is a neutral midpoint. A refusal with a nonempty selection is invalid. Malformed, missing, duplicate, or >5 selections are invalid: one rescue, then a failed packet.
 
 ### Design, request count, cost
 
-N=128 whole respondent packets per release with 128 paired deterministic seeds shared across releases (same seed per packet index on every release); canonical option order (no rotation; the packet is one coherent questionnaire). Request count: 4 releases x 128 packets = 512 panel calls plus 1 paid smoke = 513. Reserve bound per packet: 1,024 input + 2x 1,024 output tokens at the saved Alibaba prices (prompt 0.26-0.325 and completion 1.28-1.95 USD per million): panel bound USD 3.770941440, smoke USD 0.00692224, total USD 3.777863680 against the USD 5 stage stop, all inside the existing locked USD 80 repository ledger under lane `google` with reservation `pilot/resp-packet`.
