Fleet Placement specifies where the measurement-stack documents live across twenty-eight fleet surfaces, under one rule: a document's home is the surface whose object the document is about, not the surface that will find it most flattering, and every other surface carries an abstract and a link rather than a competing full definition.
Duplicate canonical definitions across domains are a splice hazard arriving through geography rather than time — the same failure the supersession banners address. Five forms are defined, including an explicit none, so that an absence is a decision rather than an oversight.
Each surface's object is established by live probe and by its canonical surface deposit rather than assumed; title matching produced false positives and is recorded as unreliable.
The placement carrying reputational consequence is named as such. The class model, which locates the archive as an owner of semantic means of production, is placed on the commercial surface — because the model's own test is disclosure at the point of use, and the point of use is the surface that sells.
