🔬 Evidence tiers
| Tier | Meaning | Permitted wording |
|---|---|---|
| Live bench | Reproduced on the published site with a dated attempt | “Observed”, “completed”, “measured” |
| Official documentation | Current vendor or WordPress.org statement | “Documents”, “states”, “lists” |
| Directory metric | WordPress.org API value captured on a date | Exact version, installs, rating, update date |
| Unverified | No current primary source and no reproduction | Explicitly “unverified”; excluded from verdict support |
Paid and SaaS products remain documentation-tier because no paid code, trial account or borrowed licence is used. A source can establish that a feature is advertised; only the bench establishes that the free plugin completes this benchmark on the current stack.
Where evidence conflicts, the live observation wins for runtime behaviour and the contradiction remains visible. See the evidence index.
