These three suites encoded pre-refactor behavior and broke the 15.10.3 release CI. - event-controller read grouping: the group header count now reflects aggregated display rows (distinct files), and a mid-turn visible-reasoning break finalizes the prior group but keeps it live until pending reads settle (97ae0fd3,b5eff5b3). - gallery harness: lsp no longer attaches an instance renderer (custom rendering removed ind9d06134), so the custom-branch regression guard is retargeted to task, which still attaches its renderer and merges call+result. - eager-todo enforcement: the prelude reminder converts to a developer-role message now that auxiliary messages map to developer for compaction (e13f2de5).
