## Prompt

The human pointed out that the agent had produced no changes after the
previous commit and expected the next incremental implementation.

## Response summary

Corrected the sequencing mistake and added explicit serialized
bindspace lifecycle policy plus generic `open_bindspace()` dispatch.
Borrowed and owned netns contexts share a policy-neutral FD-pinning
primitive while validating their public lifecycle before side effects.

## Files changed

- `tractor/discovery/_bindspace.py` - lifecycle policy, ownership
  invariants, shared pinning and dispatch.
- `tractor/discovery/__init__.py` - public policy and dispatcher exports.
- `tests/discovery/test_bindspace.py` - lifecycle serialization,
  validation and both dispatcher branches.
- `ai/tpt-backends/03_wg_tunnel_bindspace.md` - explicit lifecycle
  policy independent of transport role.

## Human edits

The human identified that the agent had accidentally repeated a
summary of already committed work instead of implementing the next
slice. That correction directly caused this lifecycle/dispatcher
change to be implemented. The agent wrote the source changes; no
direct manual edits were observed.
