- a frame's __index is its kind's method table and the Region map's 19 shared verbs dispatch in Rust: a widget method call costs one table index instead of a Lua re-entry — the idle UI tick ~20 % lighter, client-wide (2310)
- SetParent names the subtree it moved instead of giving the layout ledger up: a pooled map note's recycle no longer re-derives the whole interface, and a Questie quest-log change's worst frame halves, 166 → 83 ms (2314)
- thirteen single-store windows — honor, talent wipe, the dialog verbs, scoreboard, battlemaster, battle map, book, mirror timers, minimap ping — register their handlers; 18 kinds leave the match (2313)
- the addon-enable RE lands: DefaultState is a seeded byte, the node set is the character list, and a character the store has never seen inherits nothing — 2311's one wrong branch corrected (2316)
