## Prompt

The human requested that the bindspace plan preserve the agreed
capability, spawn-bootstrap, endpoint-role, namespace augmentation,
random-address, and teardown semantics, using `github/ns_aware` as
prototype input.

## Response summary

Updated plan-03 and the shared backend contract to separate serializable
bindspace declarations from scoped live capabilities, make namespace
entry a pre-runtime spawn operation, keep maddr paths role-neutral, and
define listen/dial provisioning plus ownership-sensitive teardown.

## Files changed

- `ai/tpt-backends/03_wg_tunnel_bindspace.md` - layer-C capability,
  bootstrap, role, teardown, test, and risk model.
- `ai/tpt-backends/00_shared_backend_contract.md` - distinguish
  transport bind selectors from process namespace lifecycle.

## Human edits

The human supplied the core architecture: structured scoped
capabilities, spawn-time namespace entry, orthogonal namespace
augmentation, source/destination-dependent provisioning, and
role-dependent teardown. They also rejected premature assumptions about
`open_bindspace()` returning an address and requested grounding in the
existing namespace prototype. The agent translated those decisions into
the plan text; no direct manual source edits were observed.
