Per-branch C51/IQN/CQL/Ens loss budgets driven by per-branch flatness =
var(Q[b]) / (σ[b]² + EPS_DIV). IQN dominates when flat, C51 yields
proportionally. CQL stays gated by existing regime_stability allocator.
Reads Q_VAR_PER_BRANCH (222..226 from Pearl 1's q_branch_stats) AND
NOISY_SIGMA (210..214 from Pearl 3 — must run AFTER both).
20 ISV slots (BUDGET_C51[190..194), BUDGET_IQN[194..198),
BUDGET_CQL[198..202), BUDGET_ENS[202..206), FLATNESS[206..210)).
StateResetRegistry: 5 new FoldReset entries.
producer_step_scratch_buf grew 111 → 131 (20 new outputs).
wiener_state_buf already at 543 (A1 sized for entire SP5 block).
Loss budget consumer migration deferred to Layer B.
