Necessity of the order cap in the R-324 re-base #

The following uncapped bridge momentRefinedIntegratedReductionOutputAt_of_generalPeelFibreLogBound consumes the per-fibre ledger R324GeneralPeelFibreLogBound at every order m ≥ 1 with no cap. This file proves that the uncapped residual ledger R324GeneralPeelLedgerFromThree cannot hold — the factorial fibre floor refutes the cancellation-carrying term-sum ledger itself, not merely its norm-inside density majorization:

Consequently the uncapped hypotheses R324LedgerThreeCrossLedger and R324LedgerThreeMixedLedger are incompatible (r324CappedRebase_crossMixed_incompatible). The valid interface therefore caps the order against truncOrder ε.

The trivial signature and its fibre #

The within-half endpoint signature of the identity pairings is the empty pair: nothing is extracted, so there are no interval endpoints.

Any entity realizing the trivial signature has extraction-free pairings in both halves: an extracted interval would contribute a left endpoint to the (empty) signature.

No cancellation at trivial external modes #

With nothing extracted there is no signed diffFactor: the deterministic profile is a plain product of Green factors and covariance factors, hence nonnegative.

The phase-free real profile of one contraction entity: the two deterministic within-half profiles against the cross covariance.

Instances For

    At α = β = 0 every contraction integrand is the coercion of the real profile: all four external characters are 1.

    Trivial-signature terms are real and nonnegative at trivial external modes: the frozen contraction term of any entity in the trivial-signature fibre equals the integral of a pointwise nonnegative real product — no cancellation is available.

    The trivial-signature fibre sum carries the factorial floor #

    The trivial-signature fibre sum is real and dominates every pure-cross density integral at trivial modes. No cancellation: all terms of the fibre are nonnegative reals, and the all-cross subfamily contributes exactly its summed density.

    Nonexistence of an uncapped constant #

    The uncapped per-fibre ledger has no constant. At ε = e⁻¹ the trivial-signature fibre sum at trivial external modes is a sum of nonnegative reals containing the full m! bijection family; the ledger caps it by 4^{2m}·K^m·L^{m-1} = (16K)^m, which the proved factorial floor defeats.

    The uncapped cross and mixed ledgers cannot both hold: their composition would produce the unavailable uncapped peel ledger.
