CORE DEFINITIONS
===============
Nothing := Empty
Recognition (A B : Type) := {recognizer : A, recognized : B}
MP : Prop := ¬ ∃ _ : Recognition Nothing Nothing, True

RecognitionStructure := {U : Type, R : U → U → Prop}

chainFlux (L : Ledger M) (ch : Chain M) : ℤ := phi L (Chain.last ch) - phi L (Chain.head ch)

THEOREM PROOFS (LEAN FUNCTIONS)
===============================

T1: mp_holds : MP
- Proof: intro ⟨⟨r, _⟩, _⟩; cases r
- Logic: Empty type has no constructors

T2: T2_atomicity {M} [AtomicTick M] : ∀ t u v, postedAt t u → postedAt t v → u = v
- Uses: unique_post from AtomicTick class
- Logic: existential uniqueness implies equality

T3: T3_continuity {M} (L : Ledger M) [Conserves L] : ∀ ch, ch.head = ch.last → chainFlux L ch = 0
- Direct: Conserves.conserve (interface axiom)
- Bridge: discrete continuity equation

T4: T4_unique_on_component {δ} {p q : Pot M} (hp : DE δ p) (hq : DE δ q) {x0 y} (hbase : p x0 = q x0) (hreach : Reaches x0 y) : p y = q y
- Uses: diff_const_on_ReachN via edge_diff_invariant
- Logic: constant difference propagates along paths

T5: T5_cost_uniqueness_on_pos {F : ℝ → ℝ} [JensenSketch F] : ∀ {x}, 0 < x → F x = Jcost x
- Uses: AveragingDerivation interface + exp-axis agreement
- Logic: symmetry + unit + averaging → unique cost

T6: eight_tick_min {T} (pass : Fin T → Pattern 3) (covers : Surjective pass) : 8 ≤ T
- Uses: no_surj_small via cardinality argument
- Logic: cannot cover 2^3 patterns with < 8 elements

T7: T7_nyquist_obstruction {T D} (hT : T < 2^D) : ¬ ∃ f : Fin T → Pattern D, Surjective f
- Alias: no_surj_small
- Logic: cardinality obstruction

T8: LedgerUnits.equiv_delta (δ ≠ 0) : DeltaSub δ ≃ ℤ
- Maps: n·δ ↦ n (non-canonical for δ ≠ 0)
- Logic: subgroup isomorphism via Classical.choose

KEY LEAN TECHNIQUES USED
========================
1. Inductive types: ReachN, Chain construction
2. Classical logic: Classical.choose for existence
3. Typeclass system: AtomicTick, Conserves, SymmUnit
4. Cardinality arguments: Fintype.card bounds

inBall (K : Kinematics α) (x : α) (n : Nat) (y : α) : Prop := ∃ k ≤ n, ReachN K k x y

ballP (K : Kinematics α) (x : α) : Nat → α → Prop
| 0, y => y = x

- unit0 : F 1 = 0

AveragingDerivation (F : ℝ → ℝ) extends SymmUnit F : Prop :=
- agrees : AgreesOnExp F (∀ t, F (Real.exp t) = Jcost (Real.exp t))

LogModel (G : ℝ → ℝ) : Prop :=
- even_log : ∀ t, G (-t) = G t
- base0 : G 0 = 0  
- upper_cosh : ∀ t, G t ≤ ((Real.exp t + Real.exp (-t)) / 2 - 1)

CLASSICAL BRIDGE MAPPINGS
=========================
T3: Conserves ↔ DiscreteContinuity (∂ρ/∂t + ∇·J = 0)
