# Class LittleGhost::CodeMode::ProgramResult

Documentation version: Edge

Canonical HTML: https://littleghostai.org/docs/LittleGhost/CodeMode/ProgramResult.html

Describes one observation of a code-mode program. Its output contains text
produced since the previous observation.

`value` carries the completed program's language value when the engine
supports one. `status` is `:completed`,
`:still_working`, `:terminated`, or `:error`.
`error` contains a model-program error; lifecycle and cleanup failures raise
instead.
