# Extra-pipe teardown

The learner can `close()` the extra handles they hold when a minted conversation is done, keep the dedicated worker and its implicit port, treat a later extra post as a drop (no throw), and refuse `terminate()` / GC / the `close` event as the teardown API. That is now the floor.

Evidence: the learner said they passed lesson 7 (teardown lab + checks).

Implications: issue #24’s success criteria are covered. Next is interleaved retrieval of choose/reject plus teardown so storage strength can catch up with fluency. Do not close #24 until that drill is passed.
