## Prompt

After rebasing the TIPC backend branch onto current `main`, inspect the
result before the human force-pushes it. Repair and verify any integration
problems, then provide a proper `/commit-plan` rather than an ad hoc staging
and commit suggestion.

## Response

The range-diff showed that the two omitted pformat commits were already
present on `main`, while the conflict resolutions correctly retained current
platform-aware transport behavior. It also exposed a lost `uv.lock` update:
`pyproject.toml` retained the unreleased WG-capable `multiaddr` source pin,
but the lock still selected the PyPI release.

> `git diff HEAD~1..HEAD -- uv.lock`

Regenerated the lock against current `main`, preserving its newly landed
dependencies while selecting py-multiaddr revision `f86519da`.

The full test suite then found that eagerly importing `Multiaddr` from the
new TIPC module violated `main`'s cold-import contract.

> `git diff HEAD~1..HEAD -- tractor/ipc/_tipc.py`

Moved `Multiaddr` under `TYPE_CHECKING` and supplied the runtime `Any` alias
used by the sibling TCP and UDS backends, retaining lazy multiaddr loading
and runtime annotation resolution.

> `git diff HEAD~1..HEAD -- tests/test_lazy_imports.py`

Extended lazy annotation checks to the TIPC stream and updated
`mk_maddr()`'s expected runtime return type for the branch's interim
`Multiaddr|str` TIPC grammar.

Validation completed:

- `uv lock --check` passed.
- Focused lazy-import, TIPC, and multiaddr checks: 60 passed.
- Full default transport suite: 548 passed, 9 skipped, 7 xfailed,
  3 xpassed.
- Full `--tpt-proto=tipc` suite: 548 passed, 9 skipped, 8 xfailed,
  2 xpassed.

The human corrected the initial ad hoc commit suggestion and required the
repository's complete `/commit-plan` workflow.
