A general proof for arbitrary -reversible programs would need: -1. A general `post_execution_dist_general` using `eval_to_state` functions -2.

Its proofs are genuinely hard. Don't confuse the two. - ---- - -## Critical Insight #2: is_lambda_CNO Was False - -**Location**: `proofs/coq/lambda/LambdaCNO.v` - -The original definition required: -```coq -(* WRONG - was unprovable and actually false *) -Definition is_lambda_CNO (t : LambdaTerm) : Prop := - forall arg : LambdaTerm, - (exists nf, evaluates_to (LApp t arg) nf) /\ - beta_reduce_star (LApp t arg) arg. -``` - -Problem: `evaluates_to` requires existence of a **normal form**, but -`(lambda_id) Omega` reduces to `Omega` which has NO normal form. -So the termination clause is unsatisfiable for non-normalizing arguments. - -**Fix**: Removed the termination requirement entirely: -```coq -(* CORRECT *) -Definition is_lambda_CNO (t : LambdaTerm) : Prop := - forall arg : LambdaTerm, - beta_reduce_star (LApp t arg) arg. -``` - -Added `cno_application_terminates` as a separate theorem for when the -argument IS normalizing. This is the right decomposition because: -- Identity IS the essence of CNO (same as imperative model) -- Termination for normalizing args follows as corollary -- Side effects absent by construction in pure lambda calculus - ---- - -## Critical Insight #3: ProofIrrelevance for Category Laws - -**Location**: `proofs/coq/category/CNOCategory.v` - -`ProgramMorphism s1 s2` wraps a `Program` with an `eval` proof witness. -To prove category laws (associativity, identity), we need morphism equality. -Two morphisms with the same underlying program must be equal, but their -eval proof witnesses may differ. - -**Solution**: Import `Coq.Logic.ProofIrrelevance` and prove: -```coq -Lemma morph_eq_ext : - forall s1 s2 (m1 m2 : ProgramMorphism s1 s2), - morph_program m1 = morph_program m2 -> m1 = m2. -Proof. - intros s1 s2 [p1 H1] [p2 H2]. simpl. - intros Heq. subst. - f_equal. apply proof_irrelevance. -Qed. -``` - -Then category laws reduce to list properties: -- Associativity: `app_assoc` (list append is associative) -- Left identity: `app_nil_r` (p ++ [] = p) -- Right identity: `reflexivity` ([] ++ p = p by computation) - ---- - -## Critical Insight #4: cno_categorical_equiv Needs Termination - -**Location**: `proofs/coq/category/CNOCategory.v:146` - -Original statement was: -```coq -is_CNO p <-> (forall s s', eval p s s' -> s =st= s') -``` - -The backward direction is **unprovable** because you can't derive termination -from the identity property alone.

(* U (V psi) =q= V psi -- direct from hypothesis *) -+ apply HV_id. (* V psi =q= psi -- direct from hypothesis *) -``` - -### Bug 2: Cexp(RtoC theta) is real exponential, not phase - -`Cexp(RtoC theta)` computes `e^theta` (real exponential), not `e^{i*theta}` -(phase factor). For proper global phase in quantum mechanics, it should be: -```coq -Cexp(Ci * RtoC theta) (* = e^{i*theta} -- proper phase factor *) -``` - -Check the `global_phase` definition carefully before fixing. - -### Missing Axioms for Quantum Proofs - -The 3 `quantum_state_eq` proofs (refl/sym/trans) need: -- `Cmod_Cexp`: `Cmod (Cexp (Ci * RtoC theta)) = 1` -- `Cmult_assoc`, `Cmult_comm` for complex multiplication -- Properties of `Cmod` (multiplicativity, triangle inequality) - -These should be added as axioms with a note that CoqQ or Coquelicot -provides them in a full development. - ---- - -## Critical Insight #6: Infrastructure Axioms in CNO.v - -**Location**: `proofs/coq/common/CNO.v` - -The previous Opus session added these axioms that enable many proofs: - -```coq -(* State equality respects eval *) -Axiom eval_respects_state_eq_right : - forall p s s' s'', eval p s s' -> s' =st= s'' -> eval p s s''. - -Axiom eval_respects_state_eq_left : - forall p s s' s'', eval p s' s'' -> s =st= s' -> eval p s s''. - -(* CNO convenience lemmas *) -Axiom cno_eval_on_equal_states : - forall p s s', is_CNO p -> s =st= s' -> eval p s s'. -``` - -Also proved (not axioms): -```coq -Lemma cno_preserves_state : forall p s s', is_CNO p -> eval p s s' -> s =st= s'. -Lemma cno_terminates : forall p, is_CNO p -> forall s, terminates p s. -``` - -These are used extensively in StatMech.v (cno_logically_reversible) and -should be available to all proof files via `Require Import CNO.` - ---- - -## Remaining Proof Strategies - -### LambdaCNO.v: y_not_cno (HARD) - -Requires proving non-termination of Y combinator.

Need to read and -classify before attempting. - -### MalbolgeCore.v: 1 proof (NOT YET ANALYZED) - -Likely involves Malbolge-specific instruction encoding. - -### QuantumMechanicsExact.v: 3 proofs - -These are probably axiom-level (quantum mechanics fundamentals that -should be axiomatized rather than proved). - ---- - -## Closedness Infrastructure (Lambda Calculus) - -Added in LambdaCNO.v and essential for composition proofs: - -```coq -Fixpoint closed_at (n : nat) (t : LambdaTerm) : bool := ... -Definition closed (t : LambdaTerm) : Prop := closed_at 0 t = true. - -Lemma subst_closed_at : - forall t n s, closed_at n t = true -> subst n s t = t. - -Corollary subst_closed : - forall t s, closed t -> subst 0 s t = t. -``` - -The `lambda_cno_composition` theorem requires closedness hypotheses -because `lambda_compose` uses de Bruijn indices. When you apply -`(lambda_compose f g)` to `arg`, the beta reduction substitutes `arg` -for variable 0 in `(LApp f (LApp g (LVar 0)))`.
