Detect application-context mismatch after execution. Verifies applicability when correct output may not fit the actual context, registering each mismatch through a fail-closed deficit-fit certificate before adaptation, producing contextualized execution. The transformative revalidation loop is non-monotone — adapting the result mutates the evaluation target and can breed emergent mismatches; re-scan is mandatory. This is the non-monotone/transformative side of the contextualize ↔ distill boundary (distill is the monotone/read-only-of-source side). Type: (ApplicationDecontextualized, AI, CONTEXTUALIZE, Result) → ContextualizedExecution. Alias: Epharmoge(ἐφαρμογή).
