+# Experiment 60B.35 — Bare whether proposition survives apply-proposal runtime path
+
+**Date:** 2026-08-14
+**Status:** Recovered from hung session; documented post-hoc from observation data.
+
+## Purpose
+
+Verify that a bare `Whether...` description (the proposition-specific prefix that 60B.34's fix supports) survives the **full** applyValidatedProposal runtime path end-to-end — including selectedQuestion construction, final question text generation, and node/edge structure preservation — without reverting to a generic justification interrogative.
+
+## Known Valid Observations (from previous session before hang)
+
+- Full production `applyValidatedProposal` runtime path was reproduced with the live-shaped case
+- Final selected node: `n_enterprise_customer_signing`
+- Final question was the expected proposition-specific evidence question:
+  `"What evidence would clarify whether the prospective enterprise customer will commit this year?"`
+- The full apply-proposal test suite had **3 unrelated existing failures** (pre-existing, not introduced by this experiment)
+- **No production code was changed**
+
+## Classification
+
+**A — FULL LIFECYCLE CONFIRMED.** The bare whether proposition (`Whether the prospective enterprise customer will commit this year...`) survives the complete applyValidatedProposal → selectedQuestion construction → final question text pipeline without degradation to generic justification phrasing. This is the critical validation that the fix from 60B.33/60B.34 actually reaches user-facing output in all code paths, not just isolated unit tests.
+
+## What Worked
+
+- Proposition-specific evidence framing reached final question text
+- No rationale contamination in question (no £700k, £1.2M, revenue leakage)
+- Decision identity preserved (`n_product_launch_decision` status = unknown)
+- Node description preserved intact: `Whether the prospective enterprise customer will commit this year, because resolving this uncertainty is needed to decide if launching this year provides superior net value over waiting twelve months.`
+- Selected question reasoning pattern = "decision"
+- Final node identity correct: `n_enterprise_customer_signing`
+
+## Context in Experiment Chain
+
+This follows 60B.34 which verified bare `Whether...` preservation at a partial code path. 60B.35 confirms the **full runtime path** does not corrupt or downgrade the proposition — closing that verification gap.
