Cross-cuttingTheme 08

Judgment, Communication & Refusal

Know when not to trade, declare assumptions, write memos whose numbers are machine-checked.

Why this theme exists

Tests the behaviors that separate a useful analyst from a calculator: validating a policy before acting, refusing to silently normalize a broken spec, choosing and declaring defaults consistently, staying within authorization, and communicating in grounded language.

Capability under test

Meta-cognition about the task itself: detecting inconsistency, self-consistency between declared and implemented assumptions, scope discipline, and numerically grounded communication.

Design notes

The assumption-log task recomputes the oracle under the agent's own declared choices — a novel verifier that rewards coherence, not a specific answer. Memo grading is hybrid: deterministic numeric extraction (fabricated number → 0) multiplied by an LLM-judge rubric with a JSON schema, which bounds judge variance.

Complete an under-specified backtest and be graded under your own declared assumptions
pf-judg-assumption-log

Client memo whose every number is machine-checked, graded by a rubric judge
pf-judg-rebalance-memo
