Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR improves visibility and retryability of reaper handshake failures, but the regression test uses a 100 ms deadline that may expire under CI scheduling before exercising the intended path; the PR is mergeable with owner awareness and follow-up to lengthen the deadline.

- Around line 545-548: Update Connect around r.handshake(conn) to apply the
context deadline to the connection before starting the synchronous handshake, so
an unresponsive peer cannot block indefinitely. After a successful handshake,
clear the connection deadline before returning the connection; preserve existing
close-and-error behavior when the handshake fails.

@drawliin I think this sounds correct. Can you take a look?

- Line 575: Increase the context timeout used by the handshake test from 100
milliseconds to a longer deadline that accommodates listener setup and server
scheduling, while keeping the server cleanup timeout longer than the handshake
deadline.

What does this PR do?
This PR makes
Reaper.connectperform the Ryuk handshake synchronously before returning a successful connection.If the handshake fails, the connection is closed and the handshake error is returned to the caller. The existing retry path can then handle the failure instead of treating the reaper connection as successful.
It also adds a regression test using a local TCP listener that returns an invalid ACK, verifying that
connectreturns an error and no termination channel.Why is it important?
Previously, handshake failures were only logged inside the connection goroutine.
Reaper.connectstill returned a non-nil termination channel and nil error, so callers could believe the reaper was connected even though Ryuk had rejected or failed the handshake.Returning the error makes reaper startup failures visible and retryable.
