+====== Deterministic Execution ======
+[[public:99_annexes:annex-b-terms-and-definitions:start|Go up to Terms and Definitions]]
+===== Discussion =====
+Deterministic Execution is execution in which the same controlled inputs, initial conditions, rules, and processing sequence produce the same defined result or an equivalent result within specified tolerances.
+The controlled inputs may include source revisions, dependencies, configuration, tool versions, environment characteristics, credentials, provider capabilities, and execution parameters.
+Deterministic Execution reduces unintended variation by eliminating or controlling implicit defaults, mutable references, interactive choices, timing-dependent behavior, and unrecorded environmental influences.
+Within Crucible, [[public:99_annexes:annex-b-terms-and-definitions:v:version_pinning|Version Pinning]], a [[public:99_annexes:annex-b-terms-and-definitions:p:pull_lock|Pull Lock]], declarative inputs, structured logging, and non-interactive operation support Deterministic Execution.
+===== Definition =====
+//execution in which the same controlled inputs, initial conditions, rules, and processing sequence produce the same defined result or an equivalent result within specified tolerances//
+===== Source =====
+Generalized from software engineering, reproducible-build, workflow automation, systems engineering, and computational-process usage and specialized for the Crucible architecture and operational model.
+===== Note =====
+Deterministic Execution does not require every generated identifier, timestamp, network address, or provider-assigned value to remain identical. The applicable criteria determine which outputs must be identical and which may be equivalent.
+Deterministic Execution supports [[public:99_annexes:annex-b-terms-and-definitions:r:reproducibility|Reproducibility]], but Reproducibility may also require preservation of inputs, tools, environments, and evidence over time.
+===== Example =====
+A Crucible Image Build uses the same pinned repositories, installation medium, package snapshot, tool versions, configuration, and execution rules to produce equivalent hardened Machine Images across repeated pipeline executions.
