"workspaceState": "Hidden intrinsic-sized attached decoder mitigates detached WebKit black later frames. Source 45 repeated native cases plus main/legacy 15 each verify lifecycle and cells 2-4 only. Initial cells 0-1 remain diagnostic: transparent/stale draws and Windows WebKit first-frame timing remain unresolved. Bounded retries now reject wrong-time seeked events before drawing. Do not close this risk or task03 based on partial pixel acceptance."
