{"standard":"<exact article name from the list>","reason":"<one sentence: what in the spec conflicts with this standard>"}

Examples of real violations to catch: a design that requires the user or agent to REMEMBER to do something (violates "No Manual Work"); a brittle low-context check given blocking authority (violates "Signal vs. Authority"); a feature with no metrics (violates "Observability"); a change to agent-installed files with no migration path (violates "Migration Parity").

THE CLAIMED PARENT STANDARD (trusted):

Your job: decide the FIT verdict between the spec's design and this parent standard.
- "fit": the spec's core purpose is plainly an application or instance of this standard. A reasonable reviewer would not dispute it.
- "weak": there is a real but stretched/partial connection — the standard rhymes with the work but is not plainly its parent (e.g. the standard is scoped to a different domain than the work).
- "none": the spec does not fall under this standard at all, or names it only as a hand-wave.

Be strict: a hand-wave parent ("this loosely relates to coherence") is "none", not "fit". The whole point is that the fit must be INDISPUTABLE to pass.
