 "title": "Test whether a starting preference leaves a lasting mark",
 "page_title": "How to test whether a starting preference leaves a lasting mark with Proteus",
 "summary": "Install a removable preference, then read the harness with structural distance and the crystallization test.",
 "who": "A researcher asking whether an initial condition still shapes a self-evolving harness after the preference is removed.",
 "problem": "A preference can seem to persist just because the prompt still carries it, so it is unclear what the harness built on its own.",
 "outcome": "A structural distance report per surface and a crystallization reading, which shows the harness state with the disposition taken away.",
 "steps": [
  "`pip install proteus-evolve==0.4.0`",
  "`proteus run --harness minimal --arm neutral --arm review:notes --arm review:tools --seeds 4 --episodes 8 --out runs/<target>` (inferred, check the README)",
  "`proteus measure --harness minimal --out runs/<target>` (inferred, check the README)",
  "`proteus measure --travel`"
 ],
 "agent_prompt": "In the Proteus repo (proteus-evolve/Proteus), run the minimal harness with a neutral arm and a review:notes arm into runs/<target>, then run proteus measure --travel. Expected output: per-surface structural distance (added, dropped, revised) and path length for each arm. Verify that the neutral arm's path length is reported alongside the review arm's, so the two can be compared.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "30 minutes",
 "basis": "readme",
 "caveat": "The crystallization test reads the harness state, so its meaning depends on the surfaces the harness declares, and the offline minimal harness has fewer surfaces than a real agent.",
