Module composer 

Contract-driven multiline composer and generic runtime request overlays.

The runtime descriptor is the only capability source. This module does not dispatch harness-specific commands or own any agent/session behavior.

Structs

ComposerCapabilities

Composer controls copied from the SDK runtime descriptor.

ComposerModel

ComposerOverlay

One SDK-owned request displayed by the composer.

ComposerRenderer

Pure Ratatui projection of composer, request overlay, commands, and footer.

Enums

ComposerAction

Runtime action produced by one editor operation.

ComposerOverlayKind

Generic overlay category. Child approvals remain typed approvals on the wire; the child distinction is presentation metadata from the payload.

ComposerTurnState

Immediate local turn state. A submit changes this before any runtime await.
