textContent/data-placeholder probes replace inputValue/placeholder reads,
evaluate-string selectors move to the composer anchor, queued fills wait
out the submit round-trip's read-only span, and the refreshed aria goldens
drop the hover tooltip the old interaction order happened to capture.
The client-bundle preset pins the production/development exports condition
(lexical's node-condition file selects its flavor with a top-level await a
CJS bundle cannot carry); the composer carries an explicit aria-label (a
div's data-placeholder does not name it the way a textarea placeholder
did); READMEs, the composer.bar slot doc, and the Agent Note record the
editor architecture; web e2e drives the contenteditable surface.
