Two findings that change the design. First, agreement between two independent programs is far more informative than program+reasoner agreement (0.80 vs 0.58 accuracy when agreeing). Second, let me confirm how code_exec handles multiple predecessors:

Confirmed — _extract_code returns a single (last) block across all predecessors, so two programs need two code_exec nodes. Let me add that to the search space:

narration
Train (30 problems) is far more discriminative than val. The key structure for a conditional decider:
decisive+pot2with the program muted: agree 80% @ 0.96 accuracy, split 17% @ 0.00alt+pot2: agree 80% @ 0.88, split 17% @ 0.60
So decisive+pot2 gives the safest CASE A (0.96) and concentrates all failure into a CASE B that currently scores zero — exactly the profile a conditional re-solve exploits.

Both jobs alive (calibT on its pot3 batch, s2 queued behind it). Note the offline simulator predicted decisive+pot2 = 0.767 and the real end-to-end run measured exactly 0.767 — the simulator is faithful. That makes its alt+pot2 = 0.800 trustworthy, so let me upgrade the insurance graph now (pure offline, no GPU):

narration
Two results in. `3c/resolve-in-decision` = 0.800 vs `3c/transcribe-nt` = 0.767 at identical 3-call cost — putting real conditional work in the mandatory decision call beats transcription.
The closure experiment is a clean negative: terse (0.611) did not beat alt (0.633) — it cut tokens slightly but lost conditional accuracy (0.857 vs 0.903). pot3 improved code coverage (0.756 vs 0.722) at equal codeAcc. Prompt-level control of thinking length is weak on this substrate.

s2 complete. Three mechanistically-motivated effects, each confirmed (train, 60 cells):
| spec | acc | |
|---|---|---|
3c/resolve-in-decision | 0.800 | conditional re-solve in the mandatory call |
3c/nt-reasoners-first | 0.783 | reasoner wins verifier tie-breaks |
3c/transcribe-nt | 0.767 | program-writer first (the ordering bug) |
3c/resolve-in-decision-lean | 0.767 | resolver starved of solver context |
3c/nt-no-pot-pred | 0.750 | program muted entirely — loses fallback coverage |
Cache hit rate 894/1032 = 87%. The three effects are independent and combinable, so let me combine them:

narration
3c/resolve-rf = 0.783 vs 3c/resolve-in-decision = 0.800 — a 1-cell difference, i.e. noise. That has a clean mechanistic explanation: with a conditional re-solver, CASE A fires only when all candidates are identical, so the verifier's tie-break ordering becomes irrelevant. Ordering only mattered for the transcriber. I'm at the noise floor of 60 train cells, so let me stop tuning and validate on held-out val:

Val (30 cells) puts all three designs at exactly 0.567 — it cannot discriminate at that sample size. But it does confirm the gate-2 margin: 0.567 vs the best single call on val (alt 0.467, decisive 0.444).
Train now has four designs within 2 cells of each other (0.783–0.817). Rather than search more, let me spend the remaining budget enlarging the sample on the top candidates — solver traces for draw 2 are already cached, so this costs only decision calls:
