[1.3.25] - 2026-08-31

The stream-idle deadline now defaults to 30 minutes instead of 120 seconds. Reasoning models (o-series, GPT-5, extended thinking) stay silent for minutes after headers arrive; the old default killed healthy streams. Setting the API request timeout to 0 disables both deadlines.
Message list scroll, pinning, and history-load viewport state is extracted from MessageList.tsx into a dedicated viewport module — the component shrinks by ~1000 lines to presentation only.

Fixed summarized turns leaking back into the model context: the compaction watermark cut is now refused whenever the summary row is missing (windowed load miss or not-yet-committed summary), instead of silently dropping the compacted range and leaving the model with only the latest turn.
Fixed the Worker context source hiding the compacted range when the watermark's summary row was not on disk; the chat store now re-fetches a just-committed summary before applying the cut.
Fixed streamed text and thinking doubling when a gateway replayed a snapshot or the live stream, reattach, and sync echo delivered the same chunk in one frame. The Worker now takes only the incremental part of deltas, ignores reasoning_summary_text.done snapshots that duplicate streamed deltas, and the renderer no longer subscribes twice while the live send loop owns the session.
Fixed tool calls failing required-field validation when a model sent path or target_file instead of the schema's file_path / notebook_path; common aliases are now coerced onto the canonical property.
