# Canonical Machine Identifiers Stable or lower-layer identifiers used as evidence: model strings, package IDs, block-device names, URNs, source-tree paths, protocol record types, hashes, and similar machine-readable keys. ## Scanned_20260730-1314 overlay Pages 3–6, 14, 19, 29, 32–33, 36, and 37–41 show the notebook repeatedly preferring these identifiers over consumer-facing names. See [[Scanned_20260730-1314|Scanned_20260730-1314]]. ## Evidentiary boundary This note records an analytical pattern in the notebook. It does not convert page proximity into proof of causation, coordination, ownership, or attribution.
