- Enabled DEC 2026 for Alacritty/VS Code and via TERM_FEATURES Sy token.
- Stopped blanket-disabling SSH for recognized direct terminals.
- Made the DECRQM probe enable sync on a positive report, not just disable.
- Extracted synchronizedOutputUserOverride so opt-out beats force-on.
- ToolExecutionComponent was updated to skip append-only treatment for finalized blocks and pass result state into `isStreamingPreviewAppendOnly`.
- Eval rendering was changed to render full code continuously and to report append-only status only once a result exists, avoiding commitment of stale pending previews.
- 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.
- Marked expanded write previews as append-only so over-tall streaming output can commit head rows.
- Threaded resolved status-line `segmentOptions` into `#buildSegmentContext` construction.
- Added regression tests for scrollback retention and append-only state transitions.
- Fixed assistant transcript blocks to expose append-only commit-safe boundaries.
- Updated TUI live-region commit and pinned-paint logic to clamp commit-safe ends.
- Fixed long streamed assistant replies to remain in native scrollback on overflow.
- 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.
- Prevented foreground streams from committing live rows, which left a stale pending tool box above the running box.
- Added initial live-region pinned paint for ED3-risk hosts with unknown viewport.
- Reconciled stale cached DEC 2048 geometry against live OS dims on resize so content reflows.
