## Prompt

After committing explicit WireGuard peer configuration, the human
authorized the next incremental lifecycle change.

## Response summary

Added owned WireGuard interface provisioning and teardown through
cancellation-shielded pyroute2 worker calls. Role-specific policy is
validated before mutation, local addresses and explicit peers are
configured, and owned interfaces are removed on exit.
Staged review clarified role-specific test assertions, added the
second peer's endpoint-port check, included conflicting values in
policy errors and aligned annotated assignment with `/py-codestyle`.

## Files changed

- `tractor/discovery/_tunnel.py` - role policy and WG iface lifecycle.
- `tractor/discovery/__init__.py` - public lifecycle and role exports.
- `tests/discovery/test_wg_iface_lifecycle.py` - policy and cancellation
  coverage with privileged calls faked.
- `ai/tpt-backends/03_wg_tunnel_bindspace.md` - initial owned WG iface
  lifecycle contract.

## Human edits

The human selected continuation from explicit peer modeling into the
owned WireGuard interface lifecycle. During staged review, the human
requested clearer role assertions, complete endpoint checks, concrete
error values and inline annotated assignment. The agent applied those
human-directed edits; no direct manual source edits were observed.
