326 methods lifted by AST (bodies identical; ast.dump-verified) into
hermes_cli/cli_{tui,status_bar,voice,model_switch,session,stream,modal,
terminal,info,loops}_mixin.py. cli.py-internal symbols resolve via lazy
'from cli import ...' inside each method (no import cycle; patch('cli.X')
keeps working). The three 'global' writers (_skill_commands, _cli_wake_owner)
now write the cli module attribute explicitly so the origin's readers still
see them. Dropped imports left unused in cli.py; kept display_hermes_home /
build_welcome_banner as re-exports (mixins + tests resolve them via cli).
Repointed two AST change-detector tests to cli_tui_mixin.py; one test
fixture now keeps 'cli' in sys.modules across its patch.dict scope.
70 nested closures (every prompt_toolkit key handler and handler factory, the
clarify/sudo/secret/approval/model-picker/command-palette/stash display
renderers, hint/placeholder/spinner callables, process_loop, spinner_loop,
_signal_handler, wake-startup) become HermesCLI._tui_* methods; run() only
binds them (kb.add(...)(self._tui_x)). The run() locals they closed over are
published on self at their original binding sites (_tui_multiline_shortcuts,
the four paste list-cells; process_loop reads self._app). Then four zero-
back-ref prologue regions become _tui_print_startup, _tui_init_run_state,
_tui_build_key_bindings -> kb and _tui_build_layout(kb) -> (layout, style).
All moved bodies verified AST-identical modulo cli_ref->self and the free-var
rewrites; unresolved-free-name check on every new method is empty. Source-
inspection tests repointed: getsource(run) -> _tui_process_loop, AST lookup of
handle_enter -> _tui_handle_enter.
handle_enter dispatches /steer and /model inline on the UI thread while
the agent is running, calling buffer.reset() then returning. Unlike every
other early-return branch in the handler, these two skipped
event.app.invalidate(). process_command() prints through patch_stdout
(scrolls output above the prompt without redrawing the input line), so the
just-cleared input area could keep showing the submitted '/steer <text>'
until an unrelated redraw fired — looking unsent and inviting an accidental
re-submit.
Add event.app.invalidate() after reset in both inline branches to match
the sibling branches. AST regression test pins the invariant: every
reset-then-return branch in handle_enter must invalidate first.
