- Added a `proseOnlyThinking` configuration setting to suppress raw code blocks in AI thinking traces.
- Implemented `formatThinkingForDisplay` utility to replace code blocks with ellipses in the UI.
- Integrated runtime toggling and live refreshing of message components via streaming reveal controllers.
- Added a live tokens-per-second indicator to the assistant thinking pulse.
- Verified logic with new unit and integration tests for thinking block presentation.
- Standardized elision markers across all tool outputs and filters to use cohesive `[...N [type] elided...]`, `[...Nln elided...]`, and `[...xB elided...]` syntax.
- Updated documentation, prompts, and test expectations to reflect the unified elision format.
- Improved transcript viewer robustness by preventing content aliasing through path-inclusive signature hashing.

- Fixed an alignment issue where the transcript body was incorrectly offset by an extra gutter column relative to the "Agent Hub" title.
- Updated the transcript renderer to omit the redundant outer gutter and ensure file-mention rows include the standard 1-column left pad.
- Added regression tests to verify consistent gutter alignment and correct scroll behavior.
- Replaced inline chat view with a dedicated fullscreen `AgentTranscriptViewer` overlay.
- Introduced `ChatTranscriptBuilder` to enable non-incremental, full-history transcript rendering.
