# ADR-0006: Reef Production Admission
|
|
|
|
Date: 2026-07-26
|
|
Status: Accepted
|
|
|
|
## Context
|
|
|
|
Fabric topology can say that a reef hosts a rail or binds a workload, but that
|
|
does not demonstrate capacity, isolation, recoverability, or approval for a
|
|
critical internet-facing service.
|
|
|
|
## Decision
|
|
|
|
Rail and `rapp` bindings use explicit readiness states: `declared`,
|
|
`installed`, `verified`, `production-approved`, and `deprecated`.
|
|
|
|
Critical workloads require machine-readable conformance evidence plus explicit
|
|
acceptance of residual risks that cannot be automated. Mixed-rail reefs use
|
|
defined split triggers.
|
|
|
|
The detailed contract is
|
|
[`docs/reef-production-readiness-contract.md`](../reef-production-readiness-contract.md).
|
|
|
|
Who may reach a listener is a different axis:
|
|
[`ADR-0008`](ADR-0008-private-by-default-exposure.md). Production
|
|
admission does not imply a public surface. A public surface requires
|
|
this admission **and** an exposure grant.
|
|
|
|
Neither admission nor exposure is an authorization decision. Whether an
|
|
actor may perform an action on a resource is `access-engine`
|
|
([`ADR-0009`](ADR-0009-netkingdom-security-layer-interaction.md)).
|
|
`production-approved` MUST NOT be read as permission to act.
|
|
|
|
## Consequences
|
|
|
|
- `hosts_rail` and `binds_rapp` no longer imply deployability.
|
|
- `reef-railiance` may host Knative in wave 2, but Qonto cannot be called
|
|
production-approved solely from that declaration.
|
|
- Repeated evidence collection should become functional automation.
|
|
- `production-approved` is not permission to publish a listener. See
|
|
ADR-0008.
|
|
- `production-approved` is not an authorization decision. See ADR-0009.
