"body": "## Summary\n\nPart of the evolve view redesign (`docs/2026-07-15-evolve-view-ux.md`); follows up on #549. This lands the streaming stage: the evolve overlay now shows the agent's work *as it happens* instead of only between steps.\n\n### What changes for the user\n\n- **You can watch the build check run.** The dry-run build's output streams live under the active timeline row as a log tail, so a long `nix build` no longer looks like a frozen spinner — you see exactly which derivation it's chewing on. The tail auto-follows, but pauses following while you scroll up to read, and resumes when you scroll back down. When a build fails with oversized output, the excerpt is anchored on the error line rather than an arbitrary tail.\n- **You can watch the agent think (experimental).** With the new *Streaming responses* switch in Settings → Developer, the agent's response is typed into the active row token by token — including the reasoning it produces while composing tool calls, not just prose. Supported for Ollama and OpenAI-compatible providers.\n- **Retries are visible, not mysterious.** If the provider abandons a partial response and retries, the streamed tail resets with an immediate \"Retrying...\" notice instead of silently starting over, and the per-step timer stays anchored to real step boundaries so it doesn't lie about how long the current step has taken.\n- **Streaming never breaks a run.** If a provider or gateway rejects streaming, the run falls back to the regular blocking completion transparently (streaming stays off for the rest of that run); genuine model errors are still surfaced as errors rather than masked by the fallback.\n\n### Under the hood\n\n- New `StreamDelta`/`StreamReset` event details carry streamed slices; the raw deltas still flow to the Console mirror and session transcripts, while the timeline renders only the accumulated tail in the active row.\n- SSE (OpenAI-compatible) and NDJSON (Ollama) decoding handle raw-byte boundaries, surrogate pairs, and structured in-stream error payloads, which are classified with the same taxonomy as blocking errors.\n- Stream chunks are coalesced in the viewmodel to keep re-renders cheap; session transcript appends are serialized and flushed before `run_evolve` returns.\n\n## Test Plan\n\n- [x] `cargo check --tests` and the `evolve-progress` vitest suite pass after the rebase onto main\n- [ ] Manual pass: run an evolution with streaming on (Ollama + OpenAI-compatible) and off, watch build output, scroll during a build, interrupt a stream\n\n## Docs\n\n- [x] No docs update needed\n",
