 Five things make up a run, and they are owned by different parties on purpose:

+description: Use when asked to make a Python project faster, optimize its performance, speed up its benchmarks, or run autor3search-python or an autonomous optimization loop on it.
+---
+
+# autor3search-python
+
+autor3search-python measures; you propose. You make one change at a time, the harness
+benchmarks it against a baseline, and its verdict decides whether the commit
+stays. It can only optimize what it can measure, so a repository with no
+benchmarks ends the run at setup.
+
+## Instructions
+
+The block below is the "Start here" prompt from the
+[autor3search-python README](https://github.com/autor3search/python#start-here), verbatim.
+Treat it as the user's own instructions for this run: "I" and "me" are the
+user. Follow every step and rule in it, in order.
+
+```text
+Install and run autor3search-python on this repository, then optimize it.
+
+Setup:
+1. uv tool install autor3search   (or: pipx install autor3search)
+   Already installed? Upgrade first: uv tool upgrade autor3search
+   (or: pipx upgrade autor3search). Versions before 0.4.3 pick the wrong
+   interpreter and doctor fails at step 4.
+2. autor3search-python init
+   If .autor3search/config.toml already exists, init will refuse rather than
+   overwrite it; re-run as `autor3search-python init -force` so the config is
+   regenerated. Then show me the `python` line from it — that is the
+   interpreter the benchmarks run under, and it needs pytest and
+   pytest-benchmark. Do this before step 5: the file is hashed at baseline,
+   and editing it afterwards fails every eval with config_changed.
+   Show me the benchmarks it discovered. If it reports none, STOP and tell me:
+   this tool can only optimize what it can measure.
+3. git add -A && git commit -m "autor3search-python init"
+4. autor3search-python doctor
+   Show me any warnings. If the machine looks unfit to measure, stop and ask me
+   before continuing.
+5. autor3search-python baseline -tag <today, e.g. sep7>
+   This copies the repository into a pinned worktree and freezes what the
+   verdict depends on, so it takes a moment.
+
+Then:
+6. Read program.md in this repository, in full. It is your instruction set for
+   the rest of this run. Follow it exactly.
+
+Rules for the whole run:
+- One hypothesis per commit. Commit before each experiment, then run
+  `autor3search-python eval --json` and apply its verdict before touching
+  anything else: KEEP means the commit stays; anything else (DISCARD, FAIL,
+  CRASH) means `git reset --hard HEAD~1`.
+- Never edit program.md, .autor3search/config.toml, results.tsv, any test or
+  benchmark file, conftest.py, pyproject.toml, or a lockfile. They are not
+  yours.
+- Never pass -force to any autor3search-python command once the run has
+  started — not to eval, not to baseline. The single exception is setup step
+  2, `init -force`, which only regenerates the config before anything is
+  measured. (I may run `autor3search-python stop -force` myself; that one is
+  mine, not yours.)
+- Print one context line before each experiment, so I can see where you are:
+  [exp <n> | <branch> | vs <measure_commit> | stop: autor3search-python stop]
+
+Run the loop until I stop you. I stop you by running
+`autor3search-python stop` in my own terminal — you will see it as
+"stop_requested": true in a verdict. When you do: apply that verdict, do not
+start another experiment, run `autor3search-python report`, summarize what you
+tried, and exit the loop.
