# Raw output - model bindspace capabilities

The human authorized the next incremental Layer C change after
committing endpoint namespace visibility.

> `git diff HEAD~1..HEAD -- tractor/discovery/_bindspace.py tractor/discovery/__init__.py tests/discovery/test_bindspace.py ai/tpt-backends/03_wg_tunnel_bindspace.md`

Added frozen, serializable `BindspaceSpec` and
`BindspaceIdentity` models for the initial Linux netns kind. Added a
plain slotted `BindspaceHandle` which carries ownership and an optional
namespace FD without being serializable by default msgspec encoding.

The live handle validates declaration/identity kind and name, ownership
values, non-negative FDs and FD/inode correspondence. Serializable
models reject empty identities and kinds without implementations.

Added round-trip, non-serialization, identity-mismatch, empty-identity
and unsupported-kind tests. Ruff passed; discovery plus
message-serialization coverage passed 125 tests with 2 xpasses.
