 ### Changed
 
+- Simplified status line subagent display by removing running state and hub hint indicators
+
 - Updated online title, memory, and classification tasks to prioritize the `tiny` model role
 
 ### Fixed
 
 - Prevented auto-generated session titles from accidentally re-shouting user all-caps text
-
 - Fixed auto-generated session titles re-shouting emphatic ALL-CAPS from the user's message. `reconcileTitleCasing` (`packages/coding-agent/src/tiny/text.ts`) restored any source token with interior/repeated uppercase, so shouting like "unify ALL ERROR HANDLING" turned the model's clean sentence case ("Unify error handling…") back into "Unify ERROR HANDLING…". Casing is now restored only from mixed-case identifiers the user typed deliberately (`TinyVMM`, `iOS`, `IDs`); pure all-caps is left to the model's own output.
-### Fixed
-
 - Fixed Tavily web search with recency filters to retry once without `time_range` when Tavily returns HTTP 200 with no renderable content. ([#3633](https://github.com/can1357/oh-my-pi/issues/3633))
-### Fixed
-
 - Fixed TUI thought stream stalling and `ui.loop-blocked` warnings during subagent-heavy runs by replacing the mid-run compaction persistence check's O(n²) branch rebuild + per-pair `JSON.stringify` content compare with a one-shot persistence-key snapshot. Content equality is preserved as the rare collision tiebreaker. ([#3629](https://github.com/can1357/oh-my-pi/issues/3629))
-### Fixed
-
 - Fixed marketplace-installed plugins appearing in both the npm plugin list and the OMP extension-package status provider. ([#3628](https://github.com/can1357/oh-my-pi/issues/3628))
