Site names, host assignments and hardware inventories were scattered
through readme.md, CLAUDE.md and a unit-file comment. They belong in the
deploy matrices — the single source of infra truth — and nowhere else.
readme.md now describes roles and measured hardware classes rather than
which box is where; the GPU-contention section is written as a check to
perform rather than a named host. CLAUDE.md gains a standing rule so this
does not creep back.
