"""Synthetic fixture used for the cold-start comparison.
Usage: python3 seed.py <fresh-output-directory> <checkout> <opencode-binary>
Run once per side, before T3CODE_DEV_SEED=0 vp run dev in that checkout.
Then use the app CLI to add <output>/skill-demo with title 'Skill discovery'.
In the web app create a draft in that project, select OpenCode, type /, then /s1,
reload, and type /s1 again. No model turn is sent.
