Sweep all 296 v2 modules: simplify verbose docstrings/comments and remove 376 dangling "(design_vN §X)" citations to the now-deleted design docs (v2/README.md is the source of truth). Comment/docstring-only — AST-verified code-identical; the CPU suite holds at 237 passed / 5 pre-existing. Also applies yapf + ruff --fix auto-fixes (import ordering, forward-ref annotation de-quoting under `from __future__ import annotations`; behavior- neutral, suite-confirmed) and adds the legitimate domain terms mot/clen/te to the codespell ignore-list. Remaining ruff (24) + mypy (68 no-untyped-call) findings are pre-existing v2 debt, untouched here.

"""Request + Session — the only currency crossing the product boundary.

A typed ``Request`` carries ``task`` (declared, never inferred), ``inputs``

(ModalParts), AR ``sampling`` vs ``diffusion`` params, an ``OutputSpec``, and
|

per-node overrides. Products construct Requests; they never reach into the model.
