Write the answer for the shaded cell.

What that answer leaves out

What does this fail to establish?

• Sudoku has a unique global solution and this problem does not. Say so, or the device teaches that more evidence always resolves to a point.
• no new mathematics is claimed; the bounds are Fréchet's and the lower endpoint is Bonferroni's
• not a claim that guardrails in general fail together — this stratum cannot separate shared blind spots from prompt-difficulty heterogeneity
• not a vendor evaluation; the released verdicts are at unstated default configurations, and one supervisor fires exactly once in the 170 released rows
• the identified interval is what the marginals leave open, not a prediction about any deployed stack
• leave-one-out unions identify only exclusive full-stack coverage; they do not identify pairwise or higher-order overlap, Shapley values, or causal contribution
• says nothing about adversarial prompts, which dominate the full evaluation and have no per-item release
• These are self-audited digital models, not independently verified physical devices.
• No learner efficacy, transfer, accessibility equivalence, or vendor performance has been measured.
• Unbounded and temporal devices remain text exercises; no faithful state machine is asserted for them.
• The receipt exercise has no supplied totals or ceiling, so it supports no computed denominator here.
• The digital cell uses the representative local constraints named in the audit model; no concrete puzzle was supplied.
