Configuration
Host contract for the reusable configuration-editor panels (ParameterPanel, ControlOverridesPanel, RVOverridesPanel, and the composite ConfigurationEditorPanel).
The interface decouples those panels from any specific controller so they can be re-mounted in other GUI surfaces — the Scenario app's per-scenario editor window in particular, which hosts the same three panels against a per-scenario edit-buffer rather than a process-wide controller — and so future non-Swing hosts (web form, CLI editor) can drive the same state shape.
What the host owns
Snapshots captured at probe time (modelDefaults, controlsSnapshot, rvSnapshot) — the panels read these once for rendering placeholder text, column populations, and table rows. They do not change during the editor's lifetime.
Live state (runOverrides, controlOverrides, rvOverrides) — the panels both subscribe to these flows (to update their displays on external mutation) and push changes via the matching mutators below.
Validation bus + EDT-confined coroutine scope — for field-level error markers and panel-internal collectors.
What the panels do
Subscribe to the StateFlows for display sync.
Call the mutators when the user edits a field, toggles an override checkbox, or clicks Reset-all.
Decorate field/row appearance from validation findings via validationBus.
The panels never reach back to host concerns like Save, Run, window title, or dirty-tracking — those belong to the parent frame/controller and are above this interface.
Implementations
ksl.app.swing.single.SingleAppController— owns single-app state directly.ksl.app.swing.scenario.ScenarioEditBuffer— adapts aScenarioSpec-shaped buffer to this contract for the per-scenario editor window.
Properties
Pending control overrides (all three families).
Probe-time controls snapshot; drives the rows of ControlOverridesPanel.
Probe-time author-curated catalog of nominated inputs and outputs, or null when the model supplied none. Optional metadata: editor panels may use it to label and feature the salient inputs/outputs, but must behave exactly as before when it is null. Defaults to null so hosts that do not supply a catalog need not override it.
Probe-time model defaults; drives placeholder text in ParameterPanel.
Pending run-parameter overrides.
Pending RV-parameter overrides.
Probe-time RV snapshot; drives the rows of RVOverridesPanel.
Validation feedback bus; panels decorate field/row state from it.
