Holography Seam Ledger Discharge B2 Unique Zero Of Anomaly Ledger

The unique deficit-free period

In the Recognition Science framework, a ledger is a discrete record of events, and its cost is the forced price of recognizing those events. The theorem b2_unique_zero_of_anomalyLedger establishes a precise fact about one such cost function: for any positive rate parameter κ and any positive period T, the cost C(κ, T) equals zero if and only if T equals 2π/κ. This period, called the deficit-free period, is the unique time interval at which the ledger's per-cycle seam cost vanishes. The result holds for the specific cost reading f(t) = t/2 − 1, which is the anomaly reading in the framework's terminology.

The proof rests on a trace bound for 2×2 matrices that preserve a certain pairing form. For such a matrix W with a positive real eigenvalue x, its trace equals x + x⁻¹, which is always at least 2, with equality exactly when x = 1. This bound, combined with the calibration condition f(2) = 0 and the faithfulness condition f(t) ≠ 0 for t > 2, forces the zero set. The key insight is that the exact form of the anomaly reading is not load-bearing: the same conclusion follows for any reading function satisfying those two conditions. The theorem is proved in the machine-checked library of formal theorems, with no unproved assumptions.

The framework also proves that the anomaly reading is equivalent to a more general conservation condition, and that the cost function equals the framework's canonical cost J(x) = (x + 1/x)/2 − 1. However, the theorem does not claim that the physical seam cost actually satisfies the ledger closure pricing condition. That physical instantiation, whether a real system's cost report and audit discipline realize the framework's axioms, remains an open target. The theorem's power is conditional: if the ledger closure condition holds, then the unique zero is forced.

What the theorem does not claim is equally important. It does not identify the rate parameter κ with any physical horizon clock rate; that identification is a separate open question. It does not assert that the anomaly reading is the only possible reading, only that the zero set is independent of the reading's exact form. And it does not prove that the cost function J is the unique cost satisfying the closure condition; that uniqueness is a separate theorem in the framework. The declaration is a precise, conditional statement about a mathematical structure, not a claim about any specific physical system.

/-- **B2 from the weak residue (THEOREM, FORCED-CONDITIONAL on

deficit-free period `β = 2π/κ` is the UNIQUE zero of the per-cycle cost:

* off the period, `turnRatio ≠ 1` (`turnRatio_eq_one_iff`, CITED), so the trace is
  strictly above 2 (`conserving_trace_bound`) and faithfulness forbids a zero;
* at the period, `turnRatio = 1`, the trace is exactly 2, and calibration fires.

The character anomaly appears NOWHERE: the B2 zero set is forced by conservation,
delivery, calibration, and faithfulness alone. -/

What this page does not claim

The theorem does not identify κ with any physical horizon clock rate. The theorem does not prove that the anomaly reading is the only possible reading. The theorem does not assert that the physical seam cost satisfies the ledger closure condition.
