Overview

Replays the engine's bulk SAX record table (leptris#1298) to the bridge protocol. One drain crossing replaces the per-event recorder replay; the only String materializations left are the name/value/text data the handler actually consumes. End events reconstruct from the records' parent indices with a name-carrying stack — pre-order records make a parent mismatch the exact close boundary, and self-closing elements pop at their next sibling, matching the callback engine's event stream.
