The user asked to continue the piker broadcast-consumer audit after committing the Deribit ownership fix. The next isolated item was IB’s actor-local _quote_streams cache, which retained a raw channel owned by its first caller and constructed competing broadcaster roots for later callers.
git diff HEAD~1..HEAD -- piker/brokers/ib/feed.py
Factored _open_aio_quote_channel() as the raw asyncio-channel context and made open_aio_quote_stream() cache that context by symbol through maybe_open_context(). Every caller now receives a lexical child from the retained LinkedTaskChannel broadcaster, while the raw source remains alive until its final cache user exits. Removed the manual _quote_streams registry and teardown mutation.
git diff HEAD~1..HEAD -- tests/test_ib_broadcast.py
Added a concurrent ownership regression using real Tractor broadcast state. It proves miss and hit callers use the same symbol/context factory, receive the same quote through distinct children, close independently, and leave the owner live after the hit exits.
