Representations

Compressed forms competing on measured preservation. An envelope is a fact about a cohort and a k, earned by an executed trial; a declared representation that has never been trialled shows none.

this envelope -> the same envelope on a learned model, whose geometry differs from a hashed-token backend; recall at 5 -> recall at any other k

cannot_infer
poor preservation here -> poor preservation generally; a hashed-token embedding spreads signal uniformly across dimensions, which is the worst case for sign quantization

a crude projection -> a learned one; discarding dimensions is not dimensionality reduction

a cosine reported on model tensors -> a preservation envelope for candidate retrieval; these are different axes and different questions

a shape that works on three fixtures -> an envelope; three examples establish that the path exists, not what it preserves
