# Complete the hub-extension conformance profile

## Goal

Turn the deliberately open Tier-2 checks in
`helixforge.hub-extension/0.1.0` into executable framework evidence without
making an extension repository implement hub-core policy. OPS-WP-0003 passed
the current C1/C3/C4/C5/C6/C8 profile; this residual owns C2, C7, C9, and C10.

## Add registry resolution evidence

```task
id: HUB-WP-0009-T01
status: todo
priority: medium
state_hub_task_id: "0702bd43-146e-5f5d-9bf3-81ae4a367afb"
```

Implement C2 against the public registry/discovery contract, including missing,
ambiguous, and stale registrations. Keep repository and capability authority in
their owner systems and make registry audit history queryable.

## Enforce raw-port configuration policy

```task
id: HUB-WP-0009-T02
status: todo
priority: medium
state_hub_task_id: "427a663c-fbd5-55c8-9889-6946a5072932"
```

Implement C7 so production configuration cannot bypass named ports or silently
enable overlapping authorities. Cover policy allow, deny, and unavailable
behavior without embedding credentials in fixtures.

## Prove dependency-aware readiness

```task
id: HUB-WP-0009-T03
status: todo
priority: high
state_hub_task_id: "41476950-bb3f-5fc3-8d44-bea3d851e5f9"
```

Implement C9 for every enabled port and compatibility group. Readiness must
fail when its required database, policy, registry, or owner projection is
unavailable while unrelated disabled groups remain non-blocking.

## Add contract-version negotiation

```task
id: HUB-WP-0009-T04
status: todo
priority: medium
state_hub_task_id: "90849a2d-c3ac-5fca-b86f-88cef2803957"
```

Implement C10 using descriptor min/max versions and explicit incompatibility
responses. Include the 0.1 compatibility adapter and ensure future versions do
not silently accept a contract they cannot interpret. Record tenant-isolation
coverage separately if it still exceeds this profile.

## Acceptance

- [ ] C2, C7, C9, and C10 are automated and fail closed
- [ ] The conformance report distinguishes unsupported from pass/fail
- [ ] Ops Hub's canonical owner package passes the expanded profile
- [ ] Any tenant-isolation residual has its own live owner record
