## Prompt
|
||
|
|
|
||
|
|
After committing the foundational bindspace capability model, the
|
||
|
|
human authorized the next incremental Layer C change.
|
||
|
|
|
||
|
|
## Response summary
|
||
|
|
|
||
|
|
Added a borrow-only existing-netns context manager which pins stable
|
||
|
|
identity through an open FD and always releases that local descriptor.
|
||
|
|
The API does not create, enter or remove namespaces and rejects named
|
||
|
|
path traversal.
|
||
|
|
Staged review renamed the context to `attach_netns()`, introduced the
|
||
|
|
readable `CURRENT_NETNS` alias and made key validation errors identify
|
||
|
|
their exact owning field.
|
||
|
|
Follow-up review made the empty-key error spell out that `None` is
|
||
|
|
written as `CURRENT_NETNS` for `BindspaceSpec.key` declarations.
|
||
|
|
|
||
|
|
## Files changed
|
||
|
|
|
||
|
|
- `tractor/discovery/_bindspace.py` - existing-netns lifecycle and key
|
||
|
|
validation.
|
||
|
|
- `tractor/discovery/__init__.py` - public lifecycle export.
|
||
|
|
- `tests/discovery/test_bindspace.py` - current, named, missing and
|
||
|
|
traversal coverage.
|
||
|
|
- `ai/tpt-backends/03_wg_tunnel_bindspace.md` - borrow-only lifecycle
|
||
|
|
contract.
|
||
|
|
|
||
|
|
## Human edits
|
||
|
|
|
||
|
|
The human selected the previously deferred borrow-only netns lifecycle
|
||
|
|
as the next incremental Layer C change. The agent implemented the
|
||
|
|
source changes. During staged review, the human selected
|
||
|
|
`attach_netns()` terminology, requested explicit
|
||
|
|
`BindspaceSpec.key = CURRENT_NETNS` semantics and field-specific key
|
||
|
|
validation. Follow-up review requested the validation error itself
|
||
|
|
connect `None` to `CURRENT_NETNS`. The agent applied those
|
||
|
|
human-directed edits; no direct manual source edits were observed.
