## Prompt

The human asked to proceed with WireGuard Layer B from PR #505's
head, using the established one-change-per-turn workflow and
finishing with a commit plan. This turn was limited to read-only
pyroute2 inspection; peer verification and bindspace provisioning
remain later changes.

During review, the human required the generated Python to follow the
deployed `/py-codestyle` rules and asked for the medium-term plan to
remove pyroute2's asyncio I/O runtime from the Trio read path.

## Response summary

Added Linux-only read helpers for WireGuard device and peer public
keys. Pyroute2's synchronous API is fully contained in a Trio worker
thread, supports named netns reads without creation side effects,
validates decoded keys and always closes the netlink client.
Follow-up edits added the required local annotations, boolean layout,
helper docstrings and 69-column source formatting.

## Files changed

- `pyproject.toml` - Linux-only `wg` optional dependency.
- `uv.lock` - resolved pyroute2 0.9.6 metadata.
- `tractor/discovery/_tunnel.py` - read-only WireGuard helpers.
- `tractor/discovery/__init__.py` - public helper exports.
- `tests/discovery/test_wg_inspection.py` - fake-backed netlink and
  worker-thread regressions.

## Human edits

The human chose the exact #505 head as a stacked base, required
incremental changes ending in commit plans, and limited this turn to
read-only pyroute2 inspection. The human then identified that Ruff
success had not established `/py-codestyle` compliance and directed
the agent to correct the Python-specific annotation, documentation
and layout rules. No direct manual source edits were observed.
