"""Shared base dataclass for ``pybmodes.workflows.*`` results.

Each workflow function returns a :class:`WorkflowResult` subclass.
The base carries the three fields the CLI needs to translate a
workflow outcome into terminal output + an exit code; subclasses
add the workflow-specific typed payload.

Exit-code convention (matches the existing CLI semantics so any
downstream caller scripting ``pybmodes ...`` keeps working):

- ``0`` — success. Includes "WARN-verdict but tolerated" cases
  for validate; warnings are informational, not failures.
- ``1`` — verdict failure (e.g. ``validate`` returned FAIL,
  ``patch`` ran but a block ended at FAIL after re-fit).
- ``2`` — usage / IO error (missing input, malformed deck,
  conflicting flags). Workflows raise rather than return for
  these; the CLI catches and translates.

Each entry is a complete line (no trailing newline expected; the CLI adds one). Empty when the workflow has nothing to say. errors : list[str] Error-level lines the CLI prints to stderr.
