It is what makes the `alias#N` ids on findings[].raiserSeat, adjudications[].seat and runStats[].seat resolvable from the verdict ALONE. Bench-only: 'claude' is never a seat, so this must never be joined positionally to `council`. ABSENCE DOES NOT MEAN the bench had no repeated alias — it means no seat table is available; a verdict written before v4.8, or assembled by hand, has none. `items` is deliberately unconstrained: `council report` accepts any array here and falls back to alias space WHOLE unless every element is an object carrying a string `id`, rather than failing to render."

Carried through from the tally record: after the seat-aware raiser exclusion, at least one AGREEING peer of this finding shares the raiser's alias — corroboration that is real but came from another seat of the same model, so it is not independent. WRONG IN BOTH DIRECTIONS, by construction: the comparison is on the ALIAS only. It MISSES one model reached under two aliases (e.g. --models gpt-5,openai/gpt-5), because votes carry no resolved-executable id. And it FIRES FALSELY on a SPLIT alias — one alias whose two seats resolved to different executables — telling a reader to discount a genuinely independent cross-executable corroboration. The reliability ledger keys identity on (alias, resolvedModel) for the same run, so the two documents can disagree about what 'the same model' means. Treat this as 'worth a second look', never as proof."
