Abstract The auditability of large language models is frequently approached as a problem of understanding what occurs inside the neural network. This approach is necessary but incomplete. Contemporary language models perform computation through distributed numerical representations that can encode competing, incorrect, unsafe, hypothetical, and contradictory possibilities without necessarily expressing or acting upon them. Consequently, the detection of an undesirable internal representation does not by itself establish undesirable behavior, just as the absence of an undesirable final output does not establish that the underlying system is operating safely. This thesis proposes a two-surface model of artificial intelligence auditability. Internal auditability examines the computational mechanisms contributing to model behavior, including neural activations, features, circuits, reasoning traces, and causal relationships among internal states. Operational auditability examines the externally reconstructable sequence through which information becomes classification, governance state, authority, tool use, output, and consequence. These surfaces answer different questions and should not be treated as substitutes. Internal auditability asks what computational mechanisms contributed to behavior; operational auditability asks whether the deployed system operated according to its governing rules and whether that operation can subsequently be reconstructed. The Temporal Lineage Doctrine (TLD) is introduced as an example of operational auditability because it requires governed outputs to carry temporal, revision, state, authority, evidentiary, and execution lineage. The resulting thesis argues that artificial intelligence auditing should move beyond both behavioral observation and representational inspection toward transition auditability: measurement of how computational possibilities cross boundaries of classification, epistemic status, authority, and execution.
