Proof Classification: CNO Core Theory Focus

1. Classification Principle

Priority: Core CNO properties, especially reversibility and inverse operations

Focus areas: 1. CNO identity (programs that do nothing) 2. CNO reversibility (inverse operations are CNOs) 3. CNO composition (CNOs compose to CNOs) 4. Logical ↔ Thermodynamic reversibility (Landauer/Bennett)

De-prioritize: Domain extensions (quantum, filesystem) until core is solid


2. 🎯 TIER 0: Critical CNO Reversibility (TOP PRIORITY)

2.1. 1. StatMech.v:cno_logically_reversible ⭐⭐⭐

Line: 260 Statement:

Theorem cno_logically_reversible :
  forall p : Program,
    is_CNO p ->
    logically_reversible p.

What it proves: CNOs are their own inverses (identity is its own inverse)

Status: 80% complete, needs final step

Difficulty: 🟢 EASY (5-10 tactics)

What’s needed: - Helper lemma: eval_state_eq (if s =st= s' and eval p s s'', then eval p s' s'') - OR: Simplify using "CNO preserves state, so eval p s s"

Priority: ⭐⭐⭐ HIGHEST - This is THE core CNO reversibility proof

Estimated effort: 1 hour (with helper lemma)

Dependencies: None (self-contained once helper added)


2.2. 2. StatMech.v:bennett_logical_implies_thermodynamic ⭐⭐⭐

Line: 249 Statement:

Theorem bennett_logical_implies_thermodynamic :
  forall (p : Program) (P : StateDistribution),
    logically_reversible p ->
    shannon_entropy P = shannon_entropy (post_execution_dist p P).

What it proves: Bennett’s key insight - logical reversibility implies thermodynamic reversibility

Difficulty: 🔴 HARD (30+ tactics, needs bijection theory)

What’s needed: - Lemma: Reversible programs induce bijections on states - Lemma: Bijections preserve entropy (measure theory) - May need to axiomatize or prove bijection preservation

Priority: ⭐⭐⭐ HIGHEST - Core connection between logic and physics

Estimated effort: 1 week (substantial theory)

Dependencies: Bijection theory, entropy preservation


3. 🔥 TIER 1: Core CNO Identity & Composition

3.1. 3. LambdaCNO.v:lambda_id_is_cno ⭐⭐

Line: 130 Statement: Identity function (λx.x) is a CNO

Difficulty: 🟡 MEDIUM (10-20 tactics)

What’s needed: - Assumption: arg is a value (in normal form) - OR: Weaker property: "reduces to arg eventually"

Priority: ⭐⭐ HIGH - Canonical CNO example

Estimated effort: 2-3 hours


3.2. 4. LambdaCNO.v:lambda_cno_composition ⭐⭐

Line: 151 Statement: Composing two CNOs yields a CNO

Difficulty: 🟡 MEDIUM (15-25 tactics)

What’s needed: - Prove termination of composition - Prove identity property of composition - Use properties from lambda_id_is_cno

Priority: ⭐⭐ HIGH - CNO composition theorem

Estimated effort: 3-4 hours
