Register Your Team Identity
As your first action, record your name@team. Run exactly:
python3 ~/.claude/protocols/pact-plugin/../hooks/shared/session_registry.py register --name '<your-name>@<your-team>'
Use your name/team from the spawn prompt. It self-acquires session_id and is fail-safe (internal error → no-op); a missing symlink is a shell error, not a no-op. Do NOT add a fallback or rewrite the path. Identity bookkeeping — exempt from the teachback no-Bash-before rule.
