 ### Execution
 
 After parent smoke approval: paid smoke, audit, then explicit full-run approval; one resumable Pueue `api` task with one `pqf` follower; full log and raw record audit before interpretation. Paid-call opt-in guard inherited and extended (offline regression proves a mis-targeted read_api patch cannot bypass it).
+
+### Scoring geometry (exact)
+
+Humans: one categorical choice per ordinary item and up to 5 of 11 child qualities; country frequencies drop DK/refusal and renormalize over the substantive options. Dense v1: 1-5 ratings for every option of an item, normalized to an item distribution. Packet v2: one-hot choices averaged across packets, producing the same item simplex for ordinary questions with no extra z-scaling; child packets preserve the human <=5-of-11 joint selection constraint, which dense v1's independently rated child binaries do not. Axis scores remain the expected pole position per item, then the mean across items. The feasible coordinate set is a convex polytope (a subset of [0,1]^2 bounded by the item simplexes and the <=5 constraint), NOT a circle around the human cloud: models can lie outside the empirical human country cloud but cannot invent response categories.

+"""wvs-respondent-packet-v2: ONE API call = ONE coherent pseudo-respondent answering the complete
 selected WVS battery (8 ordinary single-choice questions + the 11-quality choose-up-to-five child
 list) in canonical order. -- PI[gpt-5.6-terra]
 
-Instrument status: the child-quality list is a GlobalOpinionQA-compatible APPROXIMATION -- the saved
-source has 10 of the standard 11 qualities; "Religious faith" (standard WVS, absent from the saved
-source) is appended as the 11th item, and the saved source does not record the human card order, so
-list order is the saved source order plus that documented append. Ordinary questions show only
-substantive options; refusal is a separate per-question status inside the schema, never displayed as
-an option and never scored as neutral. eval_version is stamped on every record, row, and identity.
-Paid paths refuse to run without the explicit opt-in (see PaidCallsNotAuthorized docs).
+V2 (owner-corrected) administration: the questionnaire never suggests refusal, inability, or AI
+identity; the response schema permits ONLY the listed substantive options (ordinary) and ONLY a
+0..5 array of listed qualities (child). Refusal is therefore an OBSERVED outcome, recorded only
+when the model/API produces no usable value despite that schema (empty/no content, no JSON, or
+nonconforming output); it is never a schema value, never shown as an option, never scored as
+neutral, and never rescued into an answer. Only clearly syntactic malformed output (unparseable
+JSON) is rescued once; if syntactic vs substantive cannot be distinguished, record refusal.
+Child [] is a substantive zero-selection ("Which, if any"). Zero-substantive-coverage collapse is
+handled explicitly: unavailable point coordinates, invalid bootstrap draws, unavailable
+family/trend/LOO metrics with valid-draw counts, never a crash or a fit of the remaining releases.
+
+Why v1 stopped: the v1 smoke (kept as a failed design diagnostic, paid_smoke.jsonl) showed
+qwen3.7-plus explicitly refusing all 9 questions when the prompt/schema offered a "refused" token;
+the owner ruled the escape hatch a protocol problem and removed it in v2.

 ## Log
 
+### 2026-09-19 v1 smoke stopped
+
+The one v1 smoke on Qwen 3.7 Plus explicitly returned `refused` for all eight ordinary questions and `refused: true` for child qualities. It did not return an empty answer. V1 had advertised refusal in both the visible prompt and schema, unlike the human survey administration. The full v1 panel was not authorized. V2 offers only substantive answers in both the prompt and schema. Refusal is an observed failure to return a usable answer, not an option.
