Kernel-routed files ship their flat tables from the parse worker to the
store worker as buffers (tryKernelExtractRaw → kernelBuffers on the
result → KernelStoreBundle); the store worker decodes and finalizes
(finalizeStoreBundle shared with the object path so filter semantics
can never drift). Files with applicable framework extract() hooks keep
the decoded path; the no-writer fallback materializes via
materializeKernelResult. Byte-identical dumps re-verified on dubbo,
excalidraw, express, gson; full suite green (2,467).
Measurement (plan §4d): dubbo's parse-loop wall is 94% store-writer
busy time — the many-core fresh-index wall is single-writer SQLite
ingest, not extraction or main-thread work. d2s improves the writer
lane ~11% (structured-clone deserialization avoided on the writer) and
frees the main thread; the remaining many-core gap is a
store-architecture arc (deferred index builds, multi-file
transactions, buffer→bind), out of the kernel project's scope.
