Package app is the interactive session shell: one event loop composing the input reader, the composer editor, and the screen painter into a running terminal application.

Package editor is the composer's line editor: the multi-line buffer the user types a prompt into, with grapheme-correct cursor movement, a kill ring, undo, and atomic paste chips.

Package fuzzy ranks completion candidates against a typed pattern.

Package input decodes the terminal's raw byte stream into typed events: keys with modifiers, bracketed pastes, and focus changes.

Package mdstream partitions streamed markdown into a stable prefix and a mutable tail.

Package render turns session content into pre-styled, pre-wrapped terminal lines: markdown through a goldmark AST walk, fenced code through a chroma highlighter bucketed into the theme's syntax roles, and file changes through a width-adaptive diff view.

Package screen is the terminal renderer core for the interactive session: line-array components, a diffing painter, and scrollback-native output.

Package term manages the terminal's lifecycle around an interactive session: raw mode, the private modes the session needs (bracketed paste, focus reporting, the kitty keyboard enhancement), the terminal size, and a portable resize watcher.

Package theme is the semantic styling layer for the terminal session.
