One clean-room 4 KiB match finder feeds both: Yaz0 writes grouped eight-bit control streams behind the usual sixteen-byte header, Yay0 splits mask, link and chunk tables with big-endian offsets and a length byte for long matches. Headers, table bounds, output bounds and reference distances are all checked on the way back in. The Yay0 writer allocated its two-byte link buffer inside the token loop, which the release build refuses as a stack-overflow risk.

What changed
Yaz0BuildingBlockandYay0BuildingBlockprimitives to the benchmarkable catalogueVerification
Added NUnit coverage for:
The implementations are clean-room from the published Nintendo format descriptions; repository CI performs compile/test verification in this environment. Because these are new public building-block types, the new package README drift gate may produce a regenerated Core README artifact which will be committed verbatim if required.
