## Prompt

Investigate IB Gateway loss, silent chart survival, infected-actor
shutdown errors and leaked shared memory. Integrate pending tagged
address and broadcast-consumer compatibility work. The human required
isolated worktrees and preservation of the live setup, and selected
tractor piker_pin rather than main as the runtime fix base.

## Response summary

Created isolated piker and tractor worktrees and initially integrated
c07e3cbd and 4af885d9 without committing. That pending merge was later
aborted. The current piker scope is the original IB fail-loud patch
and its regression tests on 5eb4fc9d; neither upstream history is
merged. The live interpreter installation was not changed.

Integration-era logging and Deribit compatibility fixes were archived
outside this patch and are absent from the current worktree. The raw
companion preserves that earlier response as historical output.

## Generated files

- piker/brokers/ib/api.py: propagate actual socket disconnection with
  the last API error through the method-proxy relay.
- piker/brokers/ib/broker.py: raise on trade-event socket loss and
  propagate the disconnect event to the trade consumer.
- tests/test_ib_method_proxy.py: exercise API error plus disconnect.
- tests/test_ib_trade_events.py: preserve callback fill identity and
  raise when the callback bridge disconnects.

Existing IB fail-loud edits and their tests were copied from the
earlier session, whose provenance remains in the fill commit.
The commit plan includes these four files and both provenance logs.

## Verification

Historically, twenty selected piker regression cases passed on the
integrated tree against isolated, patched tractor sources. Those
results do not validate the current post-abort tree or installed
pinned tractor. The new exact-tree commit-plan checks remain pending;
no project tests were run during this planning pass. No live
service/container tests or installed dependency changes were performed.
Original live-worktree diff matched SHA256

## Human contributions

The human identified the dependency branches, corrected the proposed
tractor main base to piker_pin, and required a new worktree after the
agent initially started an uncommitted merge in the live checkout.
That merge was aborted and preservation was verified before isolated
work continued. The human supplied all live incident evidence.
