- nisps/pipeline/input_chain.hpp: faithful f32 port of the manifold input pipeline (invert→deadzone→circular clamp→momentum-modulated zoom→centred power→EMA→momentum update). Caller-supplied dt, internal accumulated clock (no wall clock — deterministic; matches the P1 fixtures' clock contract). Fixed-capacity velocity ring; serialisable state. - nisps/pipeline/output_chain.hpp: curve→EMA→slew→freeze(+per-output mask) chain, capacity-templated (browser cap 4096; firmware would use NOut). - nisps/core/math.hpp: + centered_power(x, exponent) (both chains use it). - bindings: nisps_pipeline_create/destroy, nisps_input_set_config(15-float wire layout)/process/reset, nisps_output_set_config/set_freeze_mask/ process/reset, pipeline state save/load, nisps_curve_apply(+batch) (ids 0-6 = Curve enum, 7 = centred power). - parity v5 Stage 7: rational (transcendental-free) traces through both chains (2 configs each) + full curve catalog — 1273 floats PASS, the pipeline floats bit-identical native↔WASM. - ctest test_pipeline.cpp: deadzone remap, circular clamp, zoom+freeze, sticky anchor, frame-rate-independent EMA, momentum zoom-out/recovery, state round-trip, slew, freeze gate/mask, reseed-on-length-change, centred-power endpoints. Part of one-core-engine-refactor P4; the manifold TS switch follows.
