"""Synthetic discovery fixtures. Run from either installed app checkout.
Usage: python3 seed.py SCRATCH_ROOT OPENCODE_BINARY T3_HOME
Use a new SCRATCH_ROOT and a fresh T3_HOME for each commit. OpenCode must be 2.2.5.
Start the dev app with T3CODE_DEV_SEED=0 and --home-dir T3_HOME after preparing settings.
Then rerun this script with --add-projects while that app is running.
No model turn is needed or sent.

#    about 2 minutes 38 seconds after its first discovery. Head showed all six.
# Both sides used the same synthetic skills; no protocol responses were mocked.
# The base also had four CPU busy workers during project 2; the failure
# on project 6 happened after those workers had stopped.
# Shared recordings show the same close/delete/retype sequence on project 6.
# Captures are cropped to the picker and input to exclude operational metadata.
