HyExec was an experimental system for wrapping Unix shell commands as fluent, composable objects in JavaScript.

Rather than treating command execution as opaque strings or immediate side effects, HyExec exposed execution parameters—arguments, options, flags, ordering, and grouping—as manipulable structures prior to execution. Command invocation was deferred until explicitly triggered, allowing execution to be described, rewritten, and composed before occurrence.

The project focused on separating execution description from execution itself. Fluent chaining and dynamic command grouping were used to express execution order as a first-class interface, independent of the underlying shell semantics.

HyExec predates any semantic or ontological framing of execution. It is documented here as an early exploration asserting that execution must first become structurally representable and inspectable before it can be meaningfully constrained, audited, or embedded within higher-level semantic systems.
