(proposition-plus-rationale) instead of a clean conversational question. **Classification: C — BOTH A + B.** Two independent defects in `extractMeaning` (lib/graph/question-formulator.js): (A) **Rationale extraction too broad** at line 108 — when label contains "status" and description starts with "Whether", the function returns `sentenceCase(strippedDescription)` which includes the full description text after the semicolon, capturing explanatory rationale (~£700k context clause). No internal delimiter logic exists. (B) **No whether→direct-question conversion** — `isInterrogativeMeaning` at line 189 treats "whether" clauses as already interrogative and passes them through unchanged via `wrapInterrogativeForTemplate`, so the output is proposition+rationale with "?" appended, not a converted question. The first meaningful divergence from 60B.20 (which produced clean "will our largest client leave if we relocate?") is at extractMeaning line 108: 60B.20's interrogative label bypasses the status+whether branch entirely, while 60B.24's nominal "signing status" label triggers it, pulling in full description including rationale. **Smallest corrective boundary:** A+C — strip rationale on extraction (split on first semicolon), then let existing evidence framing produce "What evidence would clarify whether X?" or keep direct interrogative form via decision path line 1272-1273. No provider rewrite, no target selection change, no schema change needed. Implementation readiness: A. Full trace documented in docs/experiment-60b25.md. Experiment 60B.27 ran the exact product-launch live regression on the post-60B.26 branch to verify rationale-stripping + evidence-framing end-to-end. **Classification: A — LIVE CLEAN-QUESTION FIX CONFIRMED.** The model produced `unc_customer_signing_likelihood` (kind=unknown, status=unknown) with may_cause edge to opt_launch_this_year. Core reasoning chain preserved: decision unresolved, customer-signing survives as first-class unknown, no unrelated uncertainty invented. Final question ("What evidence would clarify prospective enterprise customer signing likelihood?") uses correct evidence framing and contains ZERO rationale contamination — no £700k, £1.2M, expected revenue, or financial impact leaked into user-facing text. Source graph description preserves full rationale intact. One live Ollama call at qwen-claude:latest on http://192.168.1.111:11434. No production code changed. Minor gap identified: extractMeaning description-start check (`/^whether\s+/i`) doesn't match "Unknown whether..." descriptions, producing nominalized output instead of a full whether-clause — functionally equivalent but less natural English. Status pending Rob's review. + +--- + +Experiment 60B.31 was a live regression of 60B.29 on the post-60B.30 branch to verify that `Uncertainty over whether...` now preserves the full proposition end-to-end live. **Classification: B — FULL PROPOSITION PRESERVED BUT DIFFERENT PREFIX EXERCISED.** The model produced `n_enterprise_customer_signing` (kind=unknown, status=unknown) with a depends_on edge. Decision remains unresolved. However, the node description started with `Whether...` not `Uncertainty over whether...`, meaning 60B.30's targeted normalization was NOT exercised live. The final question ("What outcome would demonstrate enough value to justify launching?") is generic justification interrogative — same shape as 60B.29, full proposition lost from the question text but preserved in the source node description (source graph meaning intact). No rationale contamination in the final question. One live Ollama call at qwen-claude:latest on http://192.168.1.111:11434. No production code changed. The `Uncertainty over whether...` normalization is deterministic-proven (39/39 tests) but never exercised against the live model producing this exact prefix — follow-up needed to force that prefix live. diff --git a/docs/experiment-60b31.md b/docs/experiment-60b31.md new file mode 100644 index 0000000..547a594 --- /dev/null +++ b/docs/experiment-60b31.md @@ -0,0 +1,123 @@ +# Experiment 60B.31 — Live `Uncertainty over whether...` Proposition Coverage + +**Branch:** `feature/proposition-prefix-over-v0.32` +**Starting HEAD:** `d26bbfe` (HEAD of feature/proposition-prefix-over-v0.32) +**Date:** 2026-08-14 +**Status:** COMPLETE — Classification: **B** + +## Objective + +Rerun the exact 60B.29 live case to answer: + +> If the live model again produces `Uncertainty over whether...`, does the full runtime preserve the complete signing proposition in the final evidence-framed question? + +## Fixed Input + +```text +The revenue and launch-cost estimates are good enough for the decision.

The question-shape regression (generic justification vs. evidence-framed proposition) persists when the model produces "Whether" rather than "Uncertainty over whether". + +## Verification note + +This run consumed exactly one update call. The harness executed the bounded path correctly. The model produced `Whether...` instead of `Uncertainty over whether...`, meaning 60B.30's targeted regression was not directly tested live. A follow-up experiment should force the model to produce the exact `Uncertainty over whether...` prefix (e.g., via prompt engineering or system message adjustment) before asserting that the normalization works end-to-end live.
