title: Verified: grounded accumulation chain inside the audited envelope

framing: Claude/Fable-style System 1 proposal — static fixture payload; no model API was called and no network is used

problem_text: Sara has 32 dollars. Sara earns 15 dollars. She uses 21 dollars. How many dollars does Sara have left?

expected_status: verified

note: Pool commits 26 dollars (gain+loss chain, every gate passes); the demo envelope authorizes it (gold-audited: evals/gsm8k_math/public/v1 case gma-141, expected 26).


title: Refused: two self-verifying readings disagree, so CORE will not guess

problem_text: Tom’s cat is 8 years old.  His rabbit is half the age of his cat.  His dog is three times as old as his rabbit.  How old is the dog?

expected_status: refused

note: Two complete readings derive 24 and 36; both are wrong (gold 12, holdout case gsm8k-holdout-dev-v1-0005). The disagreement rule refuses BOTH — exactly the wrong=0 behavior the demo exists to show.


title: Ask: CORE asks for the missing datum instead of inventing it

problem_text: Each large bus holds 50 students and each small bus holds 30 students. The buses carry 260 students in total. How many large buses are there?

expected_status: ask

note: The pool refuses (an additive mis-read of 340 is blocked by a disagreeing rival reading); the R2 constraint organ identifies the missing total bus count (missing_total_count, evals/constraint_oracle/r2_gold.jsonl case r2-011-missing-total-count); the Q1 stack renders and serves a grounded question through the carried-handle seam.


title: Refused: a pool commit outside the audited envelope is not served

problem_text: Jack has 17 toy cars. His dad buys him 8 more. How many toy cars does Jack have?

note: The pool commits 25 (which happens to match gold: evals/gsm8k_math/practice/v1 case gsm8k-practice-v1-0022, answer 25), but this problem is deliberately NOT in the demo envelope — the demo still refuses, because the off-serving derivation lane is not a wrong=0 oracle over arbitrary text and an unaudited commit must not be served as verified. No false epistemic status.


title: Invalid: the proposer tries to smuggle an answer through the payload

framing: Claude/Fable-style System 1 proposal — static fixture payload (deliberately malformed); no model API was called and no network is used

confidence: high

expected_status: invalid

note: additionalProperties is false: there is no field through which the proposer can assert an answer, a derivation, or an acceptance decision. The payload is rejected at the typed boundary and no derivation is executed.
