## Prompt

The human requested the complete tunnelled-maddr parsing/composition
slice as an unattended batch, with every numbered requirement finished
and atomic commit plans prepared at the end. Existing human decisions
required native `multiaddr` encapsulation APIs, no hand-written peeler,
and preservation of tractor's future bindspace lifecycle ownership.

## Response summary

Implemented strict WG key codecs and native single/nested tunnel maddr
parsing and composition, integrated them into discovery APIs, migrated
the multihost example off its duplicate parser, corrected package
dependency metadata, and added focused and end-to-end parser
regressions. Verified the complete tractor suite and built both package
artifacts.

## Files changed

- `tractor/discovery/` - WG codecs, parser/composer, wrapper typing,
  public exports, and discovery dispatch.
- `tests/discovery/` - key, grammar, nesting, round-trip, and public
  boundary regressions.
- `examples/multihost/wg_lan/` - production parser migration and
  updated usage documentation.
- `pyproject.toml`, `uv.lock` - reproducible WG codec and multibase
  dependencies for checkout and package installs.
- `ai/tpt-backends/03_wg_tunnel_bindspace.md` - current layer-A state
  and future bindspace ownership.

## Human edits

The human selected the five-step scope and batch execution model,
required delegation to `multiaddr`'s encapsulation APIs, rejected
transport-shaped listener placeholders in the prerequisite commit, and
clarified that tractor will eventually provision the kernel-owned
bearer through its bindspace layer. The agent implemented and tested
those decisions; no direct manual source edits were observed during
this batch.
