- Extract duplicated thread/message pagination functions to shared utils module - Refactor pagination token parsing to use Option combinators instead of defaults - Split access token generation from assignment for clearer error handling - Add appservice token collision detection at startup and registration - Allow appservice re-registration with same token (for config updates) - Simplify thread relation chunk building using iterator chaining - Fix saturating_inc edge case in relation queries with explicit filtering - Add concise comments explaining non-obvious behaviour choices
