examples: the Riemann Hamiltonian P14 is the capacity-arm operator (149)

Intent: close the loop of ex 148 by identifying the canonical TNFR-Riemann
Hamiltonian P14 as EXACTLY the capacity-arm operator of the dual-lever -- the
structural reason it sees the primes/zeros while the pressure substrate is blind.
Unifies physics (nu_f), number theory (free monoid), and the Riemann program
(P14) under one structure (the user's synergy/centralisation direction).
Operators: none modified. Affected invariants: #1 Nodal Equation Integrity,
#4 Grammar Compliance (characterization).

Measured on the canonical P14 (build_prime_ladder_hamiltonian):
- M1: every P14 node (p,k) carries nu_f = k*log p (CAPACITY arm, 20/20 exact)
  and dNFR = 0 (PRESSURE neutral, 20/20) -- P14 puts all structural information
  on the capacity lever, the axis (log=nu_f) carrying von Mangoldt + the zeros.
- M2: inter-prime orthogonality = free-monoid freedom (ex 147) -- the ladders
  are disconnected (n_primes independent components), distinct primes are
  independent invariant subspaces = the Euler product at the operator level.
- M3: the weighted trace reproduces Z_vM(s) = -zeta'/zeta(s) (P12) to machine
  precision (certificate spectrum error 0, trace rel-error ~1e-16, overall_ok);
  the zeros are its poles (ex 148 M2).

Paradigm insight: P14 lives on CAPACITY (sees the zeros), the per-node substrate
on PRESSURE (smooth, blind) -- the two operators are on the two arms of the
dual-lever, which EXPLAINS the ex-148 dichotomy and unifies physics nu_f <->
free-monoid size-grading <-> the prime-ladder Hamiltonian.

Honest scope: P14 already exists/reproduces von Mangoldt; the NEW part is the
unifying reading (P14 = capacity-arm operator) explaining the substrate
blindness of 148. No new operator, does NOT advance RH (G4 open, S(T) in
Fix(S_n)^perp still the obstruction, program paused at T-HP). Docs: README +
AGENTS.md showcase + my-agent.md + TNFR_NUMBER_THEORY.md section 12.2.

Grammar<->number-theory<->Riemann synergy: 146 (kernel) + 147 (free monoid) +
148 (zeros on capacity arm) + 149 (P14 = capacity-arm operator).

 - **Primality as Grammatical Inertness**: [examples/07_number_theory/146_primality_grammatical_inertness.py](examples/07_number_theory/146_primality_grammatical_inertness.py) (bridges the grammar thread 139-145 to the number-theory thread 40/100-102, never connected before. The single bridge is the nodal equation itself: every operator/"word" acts on form through ∂EPI/∂t=νf·ΔNFR, and on an arithmetic node ΔNFR is the canonical §4 primality field [ΔNFR(n)=ζ(Ω−1)+η(τ−2)+θ(σ/n−(1+1/n)), prime ⟺ ΔNFR=0], so via the dual-lever (ex 37/130) the CAPACITY lever νf is a scalar gain on the PRESSURE ΔNFR. MEASURED at the nodal-equation level (NOT the canonical graph operators, which recompute ΔNFR from neighbours — the arithmetic ΔNFR is a per-node field): (M1) ONE EQUILIBRIUM, THREE READINGS — n prime ⟺ ΔNFR(n)=0 (the theorem) ⟺ local coherence C(n)=1/(1+|ΔNFR|)=1 (maximal); the primes are exactly the zero-pressure, maximal-coherence nodes (0 mismatches in [2,60]). (M2) THE CAPACITY LEVER — PRIMES ARE THE GRAMMATICAL KERNEL: under the nodal flow EPI+=dt·νf·ΔNFR every prime is FROZEN for every νf (12/12 at νf∈{0.5,1,2}), a composite drifts and its drift FACTORS exactly as (νf gain)×(arithmetic pressure) — doubling νf doubles the drift exactly (27/27); the capacity lever scales the RATE but can never move a prime, so primes are the kernel of the whole νf-lever sub-grammar. (M3) THE U2 PRESSURE AXIS — THE GRAMMAR'S CONVERGENCE TARGET IS PRIMALITY: U2 drives ΔNFR→0, i.e. C→1; the maximal-coherence target C=1 IS exactly primality, and C decreases monotonically with Ω (mean C: prime 1.000, Ω=2 0.239, Ω=3 0.130, Ω=4 0.089, Ω=5 0.085 — factorization complexity is structural coherence DEBT); a prime needs the EMPTY word (the identity of the star-free syntactic monoid, ex 145) — it is already at the convergence target. PARADIGM INSIGHT (the user's thesis realized): the grammar dynamics is a LENS that unifies the number-theory module with the operator grammar — primality is grammatical inertness. HONEST SCOPE: primality ⟺ ΔNFR=0 is the existing §4 theorem; the NEW content is the grammar-lens reading (dual-lever kernel + U2 target + monoid identity); the bridge lives at the nodal-equation level (per-node arithmetic ΔNFR, not graph diffusion); restates the theorem through the grammar dynamics, not new number theory, closes no open problem)
 - **Numbers as Words / the Dual-Lever as Monoid Gradings**: [examples/07_number_theory/147_numbers_as_free_monoid_words.py](examples/07_number_theory/147_numbers_as_free_monoid_words.py) (deepens 146 to its algebraic core, uniting physics + grammar + number theory in one statement. By the Fundamental Theorem of Arithmetic the multiplicative monoid (ℕ,×) is the FREE COMMUTATIVE MONOID on the primes — numbers ARE words: primes=letters, 1=empty word, Ω(n)=word length, multiplication=concatenation; this is the arithmetic counterpart of the operator grammar's syntactic monoid (ex 145). MEASURED: (M1) THE COHERENCE DEBT SPLITS BY COMPOSITION LAW — the three ΔNFR pressure channels (TNFR_NUMBER_THEORY §4) are distinguished by how they compose under ×: the factorization channel ζ(Ω−1) is ADDITIVE (Ω completely additive ⇒ a monoid homomorphism; P_Ω(mn)=P_Ω(m)+P_Ω(n)+ζ exact, residual 0 — the free-monoid/word-length backbone), while the divisor η(τ−2) and abundance θ(σ/n−(1+1/n)) channels are MULTIPLICATIVE (τ,σ multiplicative on coprime — the divisor lattice); so ΔNFR = 1 ADDITIVE channel (Ω) + 2 MULTIPLICATIVE channels (τ,σ). (M2) MULTIPLYING BY A PRIME = THE UNIT DESTABILIZER — building 1→2→6→30→210 one prime at a time adds exactly ζ to the factorization channel each step (C drops 1.0→0.21→0.096→0.049), and the additive channel ALONE detects primality (Ω(n)=1 ⟺ n prime, 0 mismatches in [2,80]; the §4 theorem is 3× redundant — each channel detects primality — but only Ω is the clean free-monoid backbone; primes = single letters Ω=1, 1 = empty word Ω=0). (M3) THE DUAL-LEVER = THE TWO ADDITIVE GRADINGS — the free commutative monoid on primes has two canonical additive gradings, and they are exactly the two arms of the dual-lever (ex 37/130) restricted to arithmetic: COUNT Ω (Σ exponents → the ΔNFR factorization pressure channel) and SIZE log n (Σ eₚ·log p → the νf capacity, ex 94 atom νf=log p), both exact monoid homomorphisms (ℕ,×)→(ℝ,+); Ω asks how MANY prime letters (pressure arm), log asks how BIG the word is (capacity arm). PARADIGM INSIGHT: one algebraic statement fixes the dictionary physics dual-lever ↔ free-monoid gradings ↔ primality across three modules — the synergy the user expected to be key. HONEST SCOPE: Ω-additive, τ/σ-multiplicative, primes = irreducible generators of (ℕ,×), and the FTA free-monoid structure are CLASSICAL facts; the NEW content is the TNFR-lens reading (the three ΔNFR channels split by composition law, the additive channel = the primality-bearing backbone, the dual-lever = the two gradings); restates classical multiplicative number theory through the grammar/dual-lever lens, not new number theory, closes no open problem)
 - **The Capacity Arm Carries von Mangoldt — the Riemann Zeros Live Where the Substrate Is Blind**: [examples/07_number_theory/148_capacity_arm_carries_von_mangoldt.py](examples/07_number_theory/148_capacity_arm_carries_von_mangoldt.py) (answers the user's key question through the grammar/dual-lever lens: WHICH arm of the dual-lever (ex 147) carries the arithmetic difficulty — the Riemann zeros — and why is the per-node substrate blind to it? MEASURED: (M1) THE CAPACITY ARM IS THE VON MANGOLDT SUM — log n = Σ_{d|n} Λ(d) exactly (residual ~1e-16 over [2,200]; Möbius-inverse Λ=μ*log), so the SIZE grading log (the νf arm, ex 94/147) IS the divisor-sum of von Mangoldt, and ψ(x)=Σ Λ — the Chebyshev staircase carrying S(T)=(1/π)arg ζ(½+iT), the sole open obstruction of the TNFR-Riemann program (ex 96) — is the capacity arm's summatory. (M2) THE ZEROS ARE THE POLES OF THE CAPACITY SERIES — −ζ'/ζ(s)=Σ Λ(n)n⁻ˢ (P12) blows up as a simple pole (residue 1) at ρ₁=½+14.1347i: |−ζ'/ζ(ρ₁+ε)|≈1/ε measured 9.6/49.6/249.6 at ε=0.1/0.02/0.004; by contrast Σ Ω(n)n⁻ˢ=ζ(s)·P(s) has ζ in the NUMERATOR so a zero of ζ is a ZERO of the Ω series — the PRESSURE arm does not see the zeros as poles. (M3) THE PRESSURE ARM IS SMOOTH; THE SUBSTRATE ENCODES IT, HENCE BLIND — Ω obeys the Erdős–Kac Gaussian CLT ((Ω−loglog n)/√(loglog n), spread ≈1.13 over [3,10⁵]; slow convergence because loglog n≈2.4 is tiny, but a CLT not a zero-driven oscillation); the per-node substrate encodes the pressure arm (Φ_s ← ΔNFR ← Ω), so it is structurally BLIND to the capacity/von-Mangoldt arm where the zeros live — the SAME Fix(G)^⊥ blindness measured in ex 103/116/120, S(T)∈ker(R∞)∩Fix(S_n)^⊥ being the capacity arm's oscillatory half. PARADIGM INSIGHT (the user's direction realized): the dual-lever LOCATES the Riemann difficulty — it lives on the capacity (νf/log) axis the per-node substrate does not encode, which is exactly WHY the substrate is blind (it encodes pressure ΔNFR/Ω, the smooth zero-free side). HONEST SCOPE: log=Λ*1, Λ=μ*log, and −ζ'/ζ=Σ Λ n⁻ˢ with poles at the zeros are CLASSICAL analytic number theory (P12 is the TNFR prime-ladder form); the NEW content is the dual-lever localisation of the zeros on the capacity arm + the structural explanation of substrate blindness; does NOT prove or advance RH (G4 stays open, S(T)∈Fix(S_n)^⊥ unreachable, program PAUSED at T-HP), it locates the wall on the dual-lever axis the substrate omits — a sharper statement of where the obstruction lives, not a closure)

MEASURED on the canonical P14 (build_prime_ladder_hamiltonian + verify_hamiltonian_reproduces_prime_ladder): (M1) P14 IS THE CAPACITY-ARM OPERATOR — every node (p,k) carries νf = k·log p (the CAPACITY arm, 20/20 exact) and ΔNFR = 0 (the PRESSURE arm neutral, 20/20); P14 places ALL structural information on the capacity lever, the same axis (log = νf) carrying von Mangoldt + the Riemann zeros (ex 148). (M2) INTER-PRIME ORTHOGONALITY = THE FREE-MONOID FREEDOM — the prime ladders are structurally disconnected (n_primes independent components, each a single prime's ladder), so distinct primes are independent invariant subspaces of P14 = the Euler product at the operator level = the free-monoid generators (ex 147); the prime 'letters' do not couple. (M3) THE CAPACITY OPERATOR REPRODUCES von MANGOLDT — P14's weighted spectral trace Tr(Ŵ e^{−sĤ}) = Z_vM(s) = Σ Λ(n) n⁻ˢ = −ζ'/ζ(s) (P12) to machine precision (certificate: spectrum error 0.0e+00, trace rel-error ~1e-16, overall_ok), and the Riemann zeros are the poles of this trace (ex 148 M2); P14 reaches the capacity/zeros side BECAUSE it is built on νf = k·log p. PARADIGM INSIGHT: P14 lives on the CAPACITY arm (sees the zeros), the per-node symplectic substrate lives on the PRESSURE arm (Φ_s ← ΔNFR ← Ω, smooth, blind) — the two operators are on the two arms of the dual-lever, which EXPLAINS the ex-148 capacity-sees/pressure-blind dichotomy and unifies physics νf-capacity ↔ free-monoid size-grading (ex 147) ↔ the prime-ladder Hamiltonian (P14) under one structure. HONEST SCOPE: P14 already exists and already reproduces the von Mangoldt trace — this adds no new operator and proves nothing new about ζ; the NEW content is the unifying reading (P14 = the capacity-arm operator) that structurally explains the substrate blindness of ex 148. It does NOT advance RH: G4 stays open, the oscillatory residue S(T) ∈ ker(R∞) ∩ Fix(S_n)^⊥ — the capacity arm's oscillatory half — is still the obstruction, and the program stays PAUSED at T-HP. The value is the synergy it fixes, one structure across three modules)
