Use the synthetic small propositional calculus or synthetic receipt specified here, not actual Lean execution. The original source pulse did not run Lean builds for these questions. A statement, tactic log and kernel-checked proof are different obligations. Context=[{"name":"h6","type":"P6"},{"name":"q6","type":"Q6"}], term={"kind":"pair","left":{"kind":"var","name":"h6"},"right":{"kind":"var","name":"q6"}}, claimed_type=["and","P6","Q6"]. Atomic types are uppercase names; [imp,A,B] and [and,A,B] are implication and conjunction. Terms use var, lam, app, pair, fst, snd; this toy rule forbids rebinding a context name. Give (inferred type, claimed type, exact type match?).
G001 — Use the synthetic small propositional calculus or synthetic receipt specified here, not actual Lean execution. The original source pulse did not run Lean builds for these questions. A statement, tactic log and kernel-checked proof are different obligations. Context=[{"name":"h6","type":"P6"},{"name":"q6","type":"Q6"}], term={"kind":"pair","left":{"kind":"var","name":"h6"},"right":{"kind":"var","name":"q6"}}, claimed_type=["and","P6","Q6"]. Atomic types are uppercase names; [imp,A,B] and [and,A,B] are implication and conjunction. Terms use var, lam, app, pair, fst, snd; this toy rule forbids rebinding a context name. Give (inferred type, claimed type, exact type match?).Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.
Before
synthetic proposition/term calculus or supplied synthetic receipt
After
no actual Lean build,source-digest check or kernel acceptance
Conditions: none
Apply only the specified small calculus or synthetic receipt protocol.Statement,tactic completion,term presence and kernel acceptance are separate.No Lean is run and the teaching guide is not promoted to a formal proof.
Rule: synthetic_proofterm_not_actual_kernel · Uses: G001
Before
raw context=[{"name":"h6","type":"P6"},{"name":"q6","type":"Q6"}]After
validated English-locale context=[["h6","P6"],["q6","Q6"]]
Conditions: none
Validate every context name and type,reject duplicates,and display in the specified English order without translating opaque names.

Before
path=root/left;term={"kind":"var","name":"h6"};context=[["h6","P6"],["q6","Q6"]]After
variable lookup type=P6
Conditions: none
Look up the exact name in the current lexical context.Do not treat a similar name or a missing binding as an assumption.
Rule: synthetic_variable_typing · Uses: G001, S002
Before
path=root/right;term={"kind":"var","name":"q6"};context=[["h6","P6"],["q6","Q6"]]After
variable lookup type=Q6
Conditions: none
Look up the exact name in the current lexical context.Do not treat a similar name or a missing binding as an assumption.
Rule: synthetic_variable_typing · Uses: G001, S003
Before
path=root;term={"kind":"pair","left":{"kind":"var","name":"h6"},"right":{"kind":"var","name":"q6"}};context=[["h6","P6"],["q6","Q6"]];left type=P6;right type=Q6After
conjunction introduction type=[and, P6, Q6]
Conditions: none
The two subterms have types A and B,so the ordered pair has type A∧B.Preserve component order.
Rule: synthetic_pair_conjunction_intro · Uses: G001, S004
Before
inferred type=[and, P6, Q6];declared claim=[and, P6, Q6]
After
exact structural type match=Yes
Conditions: none
Compare the inferred type structurally with the claim.Do not fill the inference from the claim.A match belongs only to this synthetic calculus.
Rule: synthetic_claim_checked_not_assumed · Uses: G001, S005

The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
