## Prompt

> Intercept Claude session
> `7b9c97c4-fff7-4ac4-97fb-35720453308e`, pick up where it
> stopped in its open worktree, finish the tunnelled-address change
> and commit plan, and prepare any outstanding context for another
> provider.

The recovered final prompt specifically called out the `uds` versus
`unix` boundary decision, absent concrete `Address.namespace`
implementations, the corrected namespace test, and the passing
focused and wider suites.

During review, the human further required that tunnelled-maddr work
delegate to `multiaddr`'s encapsulation APIs, challenged the premature
transport-shaped listener hooks and directed their removal, corrected
the long-term bearer provisioning model, and confirmed the intended
split between discovery metadata and bindspace lifecycle code.

## Response summary

Recovered the transcript and matched it to `wkts/addr_unpacking`,
audited the staged implementation, and completed the interrupted
verification and commit-plan work. The audit removed premature
transport-shaped listener hooks, widened the namespace identifier
type, updated stale import documentation, and removed an
invalid-escape warning from the maddr diagram. It also preserved the
layer-C design where tractor provisions the kernel-owned tunnel
bearer without treating it as a message transport.

## Files changed

- `tractor/discovery/_tunnel.py` - tunnel specs, address wrapper, and
  peeling helpers.
- `tractor/discovery/_addr.py` - wrapped-address recognition and
  namespace typing.
- `tractor/discovery/__init__.py` - public tunnel API exports.
- `tests/discovery/test_tunnelled_addr.py` - delegation and boundary
  regression coverage.
- `ai/tpt-backends/03_wg_tunnel_bindspace.md` - distinguish
  tractor-owned bindspace provisioning from kernel socket ownership.

## Human edits

Substantial human-directed editing occurred over several review turns:

- required use of `multiaddr`'s `.encapsulate()`/`.decapsulate()`
  family rather than a hand-rolled tunnel peeler
- rejected the premature `start_listener()`/`close_listener()` hooks
  and directed their removal from this foundational change
- corrected the documentation so tractor retains ownership of future
  bindspace provisioning while the kernel owns the bearer socket
- reviewed and accepted the placement of declarative tunnel metadata
  under `tractor.discovery`, with lifecycle code kept separate

The final source lines were applied through the coding agents, but
these design corrections and deletion decisions came from the human
review and materially shaped the patch.
