ChatRuntime.attach_contemplation(enabled=True) flips an opt-in
flag; when on, each emitted DiscoveryCandidate runs through
teaching.contemplation.contemplate before the sink writes the
JSONL line. Default off ⇒ Phase B raw output preserved byte-
identical.
Trust boundary
- Contemplation is read-only over pack + corpus.
- Without an attached discovery sink the flag is inert (no hidden
work — emission requires an observable destination).
- Active teaching corpus on disk byte-identical pre/post.
Lanes: smoke 67 / runtime 19 / cognition 121 / contemplation-
wiring 6 — all green. Cognition eval unchanged.
