| “We tested one golden case.” | Hides variant risk; ignores subkinds. | Build a subkind‑indexed matrix; add boundary tests per column. |
| “Latest data suffices.” | Non‑deterministic; un‑auditable. | Declare Γ_time windows; fail closed on expiry. |
| “Tool is trusted, so we’re done.” | Confuses TA with VA/LA; misses content risk. | Keep TA separate; add VA proofs or LA tests as needed. |
| Bridging without penalties | Understates risk; mapping gaps surface later | Apply scope‑bridge and kind‑bridge penalties to R; publish loss notes. |
| Widening G to cover evidence gaps. | Conflates applicability with available tests. | Keep G honest; expand matrix or lower claim scope explicitly (ΔG−). |
| Inferring scope from how many items match | Scope is not the same as membership | Keep Scope (where it applies) distinct from membership (which items match in the slice). |
