+## Gear namespace checkpoint — native #292 / shared #9 (2026-10-10)
+
+Character/class source category now governs item normalization, grants, equip
+and active stats independently from dungeon source. Shared profile schema 8
+migrates missing-category WoW records only for explicit WoW owners and retains
+foreign/unidentified/invalid RoM records plus assignments in recovery. Rejected
+updates leave stored bytes unchanged. Native ordinary loot stays disabled;
+boss cards and simulator reward policy retain their existing behavior.
+
+253 unique focused source tests, full-scope app typecheck and release hygiene
+pass. The composed native bundle builds, 21 selected native cases pass, and five
+public Ready WoW level-80 snapshots match the pre-change bundle with controlled
+clock/RNG. This does not certify overall balance or equipped Ready gear.
+
+No dungeon was entered for this checkpoint, so no new Cellblock Rush boss,
+GPU screenshot, browser roster/dungeon inspection, manual fight or listening
+result is claimed. The source browser build stops at missing ignored Manastorm
+assets; browser release/visual verification remains open. Native offline gear
+persistence, recovery presentation and authenticated RoM progression remain
+under #124. See docs/GAME_GEAR_NAMESPACES.md and gear-namespace-validation.json.
