The initial residual endpoint integral after the complete nested run #
The first theorem integrates the a.e. endpoint-to-run seam without changing the order in which norms are taken. The second theorem chooses every cutoff-dependent constant before the coupling, scale, pairings and traces, then combines the two within-half scale ledgers with the exact initial nested-cross order ledger.
Pure algebraic/Fubini bridge from a signed two-half collapse equality to the endpoint-norm form consumed below. The exact order identity is the only bookkeeping input; no pointwise estimate is used here.
Integrate the pointwise endpoint seam against any supplied complete-run integral estimate. This fixed-data lemma keeps the two literal terminal scale products visible for the subsequent exact order ledger.
Cutoff-uniform residual endpoint closure. The Phase-A provider and the complete-run provider are both chosen before all scale and combinatorial data. For any two compatible traces, the endpoint integral is controlled by one inserted majorant at the ambient order.
