# Raw output - outbound tunnel boundary

The human requested the next tunnelled-address slice using the same
per-step commit-plan flow. Existing design decisions require retaining
tunnel metadata until the narrow IPC transport boundary and never
teaching exact-type transport tables about tunnel wrappers.

> `git diff HEAD~1..HEAD -- tractor/ipc/_chan.py tests/ipc/test_channel_tunnel_boundary.py`

Extended channel address inputs to accept tunnel declarations, then
called `strip_tunnels()` immediately before exact-type transport lookup
and `connect_to()`. Added plain/tunnel parameterized coverage proving
both operations receive the identical TCP overlay while the original
wrapper retains its tunnel spec.

Verification included focused IPC tests, Ruff, discovery/IPC suites,
and the full tractor suite.
