"It uses the local Ollama worker for the code-edit step, but it replaces the expensive training run with a synthetic `run.log` writer so the test can finish quickly and reliably.\n",

|
"It covers:\n",
|

"\n",
|
|
"1. locating the `claw-code` repo and `nodes/autoresearch-macos`\n",
|
|
"2. verifying Ollama reachability\n",
|
|
"3. running `autoresearch setup` and `autoresearch status`\n",
|
|
"4. creating or switching to an isolated `autoresearch/<tag>` branch\n",
|
|
"5. recording a synthetic baseline\n",
|
|
"6. running one candidate packet through the local worker\n",
|

"7. finalizing the candidate with `keep` or `discard`\n",
|
|
"8. running a short automatic loop\n",
|
