"""
Lab Eval: Full Teaching Pipeline Trace — All Three Identity Packs

For each identity pack configuration, runs a complete teaching session
and traces every layer with structured output.  Nothing is written to
packs or manifolds.  The vault is in-process and session-scoped.

Outputs structured JSON to stdout.  Exit 0 always (this is an
exploration trace, not a pass/fail assertion).

To run:
    python -m evals.lab.teaching_trace
    python -m evals.lab.teaching_trace | python -m json.tool
