Verified Historiographical State: Primary document networks (municipal registers, telegraph receipts, independent eyewitnesses) establish macro-historical events independently of individual absence queries.
Multiple independent primary sources with no possibility of collusion create an overwhelming probabilistic vector that overrides isolated absence claims.
Physical travel limitations and architectural ruins (e.g. breach marks, scorched soil) form unalterable physical constraints on historical reality.
Asking "where were you at the time" confuses an individual witness location with the systemic occurrence of an event attested by hundreds of concurrent logs.
