- Fell back to generic `Request was aborted` text when no abort reason was provided.
- Adjusted tool-execution rendering to apply state-based background tinting and spacing for non-framed outputs.
- Detected framed block children and skipped extra padding and tinting so those custom renderers stay flush.

- Live-region tests were added for expanded eval output overflow and for append-only transitions from pending to finalized streaming states.
- Added `isStreamingPreviewAppendOnly` to `ToolRenderer` for per-tool streaming mode selection.
- Updated `ToolExecutionComponent` to query append-only predicates only while a call preview is streaming.

- Moved the persistent model selector default from Ctrl+L to Alt+M, preserving existing user remaps.
- Reserved Alt+M so extensions cannot shadow the model selector shortcut.

- Updated EventController to keep foreground render mode active from agent_start through agent_end so live-region rebuild remains enabled during a turn.
- Pinned stop-reason assistant errors to the editor banner and suppressed the transcript's inline Error line while pinned, then restored it on the next agent_start.
- Added tests covering error-banner suppression/restoration and eager native scrollback rebuild ordering before loading animation.
- Updated rawTextInputFromPartialJson to stop excluding values that start with '[' from raw text fallback detection.

- Added a persistent error banner so stream errors survive transcript scroll.
- Cleared the banner when the next turn starts.
- Skipped pinning for aborts and normal stops.
- Cleared native scrollback on `omp`/`omp -c` so the resumed transcript no longer stacks on the prior run's welcome screen.
- Tracked assistant block finalization so aborted streaming messages stay repaintable when status rows land beneath them on ED3-risk terminals.
- Added image-reference rendering to make `[Image #N]` placeholders clickable in chat.
- Added MIME-aware image blob materialization with extensioned sidecar paths.
- Added clickable path, line, and URL hyperlinks for read, search, and fetch outputs.
- Hardened OSC8 hyperlink emission with URI validation and control-byte/idempotency checks.
- Replaced bottom-most-block liveness with a finalization check so the live region spans every still-mutating block.
- Kept unfinalized tools repaintable when out-of-band inserts append finalized blocks below them.
- Recomputed blocks as they cross out of the live region to seal their final content.
- Added `NativeScrollbackLiveRegion` seam so components report the live suffix start.
- Stopped ED3-risk streaming from dropping sealed transcript rows above the live block.
- Appended newly sealed rows once while keeping the active tail deferred to checkpoint.
The session-tree selector collapsed to "No entries found" whenever the
default filter rejected every entry. On a fresh session that is the
normal case: `sdk.ts` writes `model_change` + `thinking_level_change`
at startup so model + thinking state survive resumes, and the default
filter treats both as bookkeeping. `selector-controller.showTreeSelector`
guards on `tree.length === 0` so the selector still opens, and the user
sees an unexplained empty panel with `(0/0)` next to a "Recent sessions"
list that does contain data.
Split the empty-state branch into three shapes:
- `flatNodes.length === 0` → unchanged "No entries found".
- `searchQuery` non-empty → "No entries match search \"…\"" plus a
Backspace hint, with the real total in `(0/N)`.
- otherwise → "N entries hidden by the current filter [mode]" plus
"Press Alt+A to show all, Alt+D for default", with the real total in
`(0/N)`.
So the fresh-session case now explains why the panel is empty and how
to widen it instead of reading as "/tree is broken".
