Method Update

internal/tui/prompt.go:96–121

Update is the promptInput's message entry point. Large pastes are swallowed into a chip and chip-aware keys handled before delegation; everything else falls through to the textarea. reconcile() runs after any value-shifting path.

// into a chip and chip-aware keys handled before delegation; everything else
// falls through to the textarea. reconcile() runs after any value-shifting path.

			return next, nil

		if handled, next := p.handleChipKey(kmsg); handled {
			return next, nil
		}
		// A key the chip-aware handlers didn't claim (a typed rune, or a cursor
		// move like Ctrl+B/Ctrl+F that the textarea owns) is about to reach the
		// textarea. Snap out of any chip first so the keystroke can't land inside
		// a label and split it: a split label desyncs reconcile, which, when two
		// chips share a label, cross-maps the survivor to the wrong paste.
