# Hub-extension conformance
`hub_core.conformance` is the reusable Tier 2/3 harness scaffold for contract
version 0.1.0. It drives only public HTTP ports, so a FastAPI `TestClient` , an
`httpx.Client` , or another compatible target can be used without importing the
runtime implementation.
The harness mutates its target. Run it against a disposable instance or a
dedicated test namespace:
```bash
hub-core api --host 127.0.0.1 --port 8010
hub-core conformance --base-url http://127.0.0.1:8010
hub-core conformance --base-url http://127.0.0.1:8010 --json
```
## Implemented profile
| ID | Tier | Automated evidence |
| --- | --- | --- |
| C1 | 2 | Packaged descriptor, manifest, and catalog validate against Draft 2020-12 schemas |
| C3 | 2 | Runtime health probe returns healthy |
| C4 | 2 | Repeated manifest registration is reported as a duplicate |
| C5 | 2 | Cataloged progress/interaction events are accepted; wrong-family and unknown events are rejected |
| C6 | 2 | Contract and scenario fixtures reject secret-shaped keys, credentialed database URLs, and private keys |
2026-09-27 23:59:35 +02:00
| C7 | 2 | Disabled compatibility groups (`/api/v2/hubs` , `/console` ) deny access without needing fixture credentials |
2026-08-21 10:58:03 +02:00
| C8 | 2 | Registry response propagates the request correlation identifier |
2026-09-27 23:59:35 +02:00
| C9 | 2 | `/readyz` reports each dependency (database, `port.repo` projection, workload projection, authorization) individually, only degrading when a configured dependency is unavailable or stale |
| C10 | 2 | A registration whose `contract_version_min` /`contract_version_max` excludes the runtime's contract version is rejected with an explicit incompatibility error |
| C2 | 2 | `GET /ports/registry/registrations/{hub_slug}` resolves missing (404) and ambiguous (two hub_slugs sharing one `reuse_surface_id` ) registrations, and `GET .../audit` returns queryable registration history |
2026-08-21 10:58:03 +02:00
| F2 | 3 | Progress and interaction fixture events appear only in their respective projections |
| F3 | 3 | Authority fixtures appear in projections with declared rebuild sources and provenance hashes |
The projection scenario is shipped in the wheel as
`fixtures/projection-rebuild.json` . Correlation and time fields are generated
per run, allowing the harness to identify its own evidence without relying on
global row counts.
## Deliberately open checks
2026-09-27 23:59:35 +02:00
F1 registry audit history at framework scale (beyond the per-`hub_slug` audit
trail above), F4 `/api/v2` consumer smokes, F5 MCP projection binding, F6
policy fail-closed behavior beyond the raw-port group check above, F7
2026-08-21 10:58:03 +02:00
telemetry rejection, and F8 migration metadata isolation require ports or
absorption slices that are not part of the T04 minimal vertical. Tenant
isolation also remains open because the 0.1 runtime has no tenant identity or
authorization context yet. These gaps must not be interpreted as passing; the
harness reports only the implemented profile above.

## Access enforcement and CI gates
`make ci-check` runs the test suite, checks the reviewed access inventory for
source drift, builds distributions and validates an installed wheel outside the
2026-09-28 12:38:04 +02:00
checkout's import path. The wheel check uses a fresh environment and refreshes
the Hub package so rebuilding the same version cannot reuse an older installation. Forgejo runs these gates for `main` pushes and manual
2026-09-28 12:26:40 +02:00
runs, using the full commit SHA and a unique temporary checkout. CI installs the
locked development and runtime dependencies first. Individual gates are
`make test` , `make inventory-check` and `make package-check` .
`tests/test_enforced_conformance.py` runs all twelve existing Tier 2/3 checks
through an explicitly enforced runtime using a real signed IAM JWT and synthetic
owner facts, policy and audit. It verifies event attribution against authorization
records. Additional journeys establish valid state, deny both reads and writes
for anonymous/invalid credentials, revoked entitlement, policy denial and
policy/audit outages, then independently read back unchanged stored messages.
These tests run in the ordinary suite; they need no external owner checkout.
The installed-wheel gate validates runtime/security imports, packaged action and
browser route coverage, contract fixtures/schemas and the migration template.
It makes no owner requests and starts no service. The separate optional Audit
Core interoperability suite still requires `HUB_CORE_AUDIT_CORE_SOURCE` and is
not silently represented as covered by ordinary CI. Local CI-equivalent success
is not a deployed Forgejo receipt or live owner/platform acceptance.
