- updateCanvasWidgetTextFromKeyboard now stamps the edit it derives and applies onto the routed event, so the app dispatch hears exactly what the retained editor did — Escape's search-field clear, its composition cancel, and the single-line ArrowUp/Down caret jumps were runtime-only before and never reached the model.
- The app-side msgForKeyboard consumes the stamped edit first and keeps its own derivation only as the fallback for events that never crossed the runtime.
- The context-menu edit path routes through the same seam and dispatches the stamped event.

- Suppress event records staged while a journaled widget_accessibility_action dispatch is on the recorder's staging stack: the verb's synthesized key/text/drop children are deterministic derivations the replayed action re-runs, so recording both dispatched every child twice on replay.
- Effect results still write through mid-action in feed-then-dispatch order, and event_count/checkpoint ordinals stay coherent with the records a replay reader actually sees.
- Pin the class end to end: repeated AX press and set_text plus the composition verbs record and replay with exactly-once input counts and one journal record per action.

- Stage a synthetic widget_accessibility_action inside dispatchCanvasWidgetAccessibilityAction when no platform tag-23 event is on the recorder's staging stack: the direct verb surfaces (embed widgetAction, automation widget_action — now delegated through the same dispatch) journaled only untargeted focus-routed children while the verb's focus write stayed unjournaled, so a first-in-session composition or set_text replayed against the wrong editor or none at all; nested inside a staged platform AX event the synthetic stage is a suppressed placeholder, keeping exactly one record.
- Add the composition kinds to the platform WidgetAccessibilityActionKind enum (values 11-13, additive) with both widget_bridge mappings, so the journal and replay's tag-23 arm carry every verb.
- Pin the class: composition first-in-session, composition while another field holds focus, and set_text first-in-session all record action-only journals and replay onto their target editor; a recorder mechanics test pins the nested placeholder.

- A CLOSED combobox's ArrowUp/Down are its open keys: the app dispatch resolves the press before any stamped edit, so the caret derivation now yields no edit there and the retained editor agrees with the model mirror; an open picker's arrows already walk into the mounted menu, and an expanded trigger without one keeps the caret jump both sides hear.
- Bump the session journal format to v4: this branch serializes the composition action codes 11-13 into accessibility-action records, which a v3 reader would have called corrupt instead of refusing as version skew; the skew message now names the version this build reads, and the skew test pins refusal of older journals too.
- Rewrite the journal's stale coverage note: every automation verb journals now (direct-surface verbs as the outer-wins widget_accessibility_action record), so the v1 do-not-journal caveat is gone.
