# Ops Hub extension package
Ops Hub implements the owner side of `helixforge.hub-extension` 0.1.0. Hub
Core owns and runs the framework ports; this repository owns the operations
descriptor, capability declarations, event boundary, compatibility bootstrap,
and evidence used to move service-catalog responsibility out of State Hub.
The canonical package is
`registry/hub-extension/v0.1.0/ops-hub.extension.json`. Its stable identity is
`capability.operations.ops-hub`; it also declares
`capability.operations.service-catalog` as an owner capability.
## Ownership boundary
| Surface | Owner |
| --- | --- |
| Descriptor, manifest, operational vocabulary, service-catalog records | `ops-hub` |
| `port.*` schemas, event catalog, registry and projection runtime | `hub-core` |
| Runtime and operator credentials | OpenBao/platform custody; never this package |
| State Hub compatibility routes during retirement | `state-hub` until their evidenced cutover |
Ops Hub is an aspect hub, not a second hub-core deployment. The API endpoint in
the manifest is a discovery reference to the hub-core-hosted compatibility
surface at `https://hub.coulomb.social/api/v2`.
## Events and legacy compatibility
The 0.1.0 port contract emits `ops.endpoint.verified` and consumes
`hub.progress.recorded`. The older `/api/v2` bootstrap seed uses
`ops-endpoint-verified`; hub-core's compatibility adapter retains that legacy
spelling. New port-native evidence uses the dotted catalog event and must not
silently rewrite historical events.
## Validation
```bash
make test
make hub-extension-check
make hub-core-conformance
make interhub-gate
```
`hub-extension-check` validates the owner package against hub-core's packaged
Draft 2020-12 descriptor and manifest schemas, checks every declared event
against hub-core's catalog, and emits a non-secret checksum receipt.
`hub-core-conformance` injects this repository's package into a disposable
hub-core reference runtime. Contract version 0.1.0 automates C1, C3, C4, C5,
C6, and C8 plus Tier-3 F2 and F3. C2 registry resolution, C7 raw-port policy,
C9 dependency-aware readiness, and C10 version negotiation are not automated
by the current hub-core harness and are not represented as passing.
`interhub-gate` is the safe post-cutover production check. It proves that the
hub-core-hosted `/api/v2` surface exposes the bootstrap resources without
requiring a credential or mutating production.
## Authenticated bootstrap
The existing `scripts/ops-hub-bootstrap-api.py` remains the idempotent
compatibility bootstrap client. It creates or reuses the hub, manifest, API
consumer, widgets, and verification event. Follow `docs/bootstrap-runbook.md`.
Operator and runtime keys are never arguments, logs, Git content, or extension
fields. Credential routing starts with:
```bash
warden route show inter-hub-bootstrap-ssh --json
```
The current route is high-risk and attended. A source change or public gate
does not authorize another live bootstrap mutation.
## State Hub retirement handoff
This package satisfies the receiving-side contract for `STATE-WP-0079` Wave
D1. Removing State Hub's service-catalog routes still requires a separate
caller inventory, projection/count comparison, rollback receipt, and explicit
production writer-cutover authorization. Owner readiness is not cutover proof.
