ingest.el's transduce() was renamed to transduce_manifold() earlier the same day on the reasoning that it 'was never signal->geometry -- it chunks already-extracted content and PACKS it into a node+edge manifold, one layer up, and it had taken the name that belongs to the primitive underneath it.' That reasoning was backwards. Producing a node+edge manifold is not a layer above transduction, it IS transduction. Signal -> one vector is the operation underneath, and its name is geometry. The layer doing it right was renamed out of the way so the layer doing it wrong could have the name. With the primitive corrected to return a Manifold, the two layers do the same kind of thing and the inversion dissolves. What is left is a real distinction about MODALITY, not layering: transduce() dispatches to a realizer that knows its modality and can name its components; transduce_bytes() is the opaque-bytes realizer, the decomposition available to a reader that knows nothing about what it is reading. It still yields components and relations, which is why it is transduction and not packing -- it just cuts on byte boundaries, so its components are positional rather than meaningful. That is a limitation of this realizer, not the definition of the operation. Renamed by modality rather than demoted by layer. A distinct symbol is still mechanically required: reusing transduce here is a conflicting-types error the moment ingest.c links el_runtime.c. lang/examples/transduce.el asserted #144's contract and would now fail, so it is replaced by the decomposition worked example: transduce a chord, persist the five components and six relations as real nodes and edges, read each part's geometry back off its own node, and ground one part while its sibling is demonstrably untouched.
