WalkthroughThe change adds ADR-0022 for authenticated, partition-scoped hub API access to the Postgres desire store. It rejects direct Postgres access and adds the ADR to the index. The remote access spike compares both options, identifies the hub API dependency for desire reads and status writes, and lists timeout, retry, backoff, and degraded-operation behavior as remaining work. Estimated code review effort: 1 (Trivial) | ~2 minutes Merge Risk: ⚪ Minimal · up to This documents the API-mediated access decision without changing production behavior, so it is mergeable with minimal current risk. 🚥 Pre-merge checks | ✅ 11✅ Passed checks (11 passed)

In `@hyperfleet/docs/spike-remote-applier-postgres-access.md`:
- Line 152: Revise the API-mediated desire traffic conclusion near the
referenced discussion to acknowledge that remote appliers now depend on API
availability for partition reads and status writes, unlike the direct Postgres
model. Document required timeout, retry, backoff, and degraded-operation
behavior before characterizing the dependency as acceptable.
- Around line 134-137: The remote applier design document must separately
specify API-to-Postgres controls, including TLS, database authentication,
least-privilege database roles beyond column privileges, and credential
rotation. Update the credential and network-control discussion near the existing
JWT, TokenRequest, and role-sketch statements, while keeping client-to-API
authentication distinct from API-to-Postgres controls.
- Line 76: Define the service-identity-to-partition authorization invariant for
the API layer: derive the partition exclusively from trusted service identity
headers and reject any caller-supplied partition override. Add tests proving
cross-partition reads and writes are denied, and retain database-level defenses
unless application-only isolation is explicitly validated as sufficient.
- Line 120: Update the latency conclusion in the document to be conditional
rather than asserting API-mediated access is acceptable. Define measurable
latency and capacity thresholds, benchmark production-sized concurrent API and
desire workloads across the remote clusters, and base the API-mediated access
decision on whether those thresholds are met.
- Line 80: Update the “Credential lifecycle” documentation to state the
effective token-revocation grace period for the deployed Kubernetes version,
including the 60-second threshold after metadata.deletionTimestamp; revise the
corresponding claim near the later decommissioning discussion as well.

In `@hyperfleet/docs/spike-remote-applier-postgres-access.md`:
- Line 76: Update the Partition isolation description to state that Envoy strips
caller-supplied identity and tenant headers, Authorino injects validated tenant
dimensions, and the API derives partition scope only from those injected headers
rather than directly from JWT claims. Explicitly require rejection of
client-supplied partition parameters and direct API routes.
- Around line 78-80: Update the remote applier authentication design to define
cross-cluster token validation and partition mapping: specify the accepted
issuer, JWKS or TokenReview trust path, API audience, allowed service-account
subjects (including any system identity), and subject-to-partition mapping. Also
document how Authorino injects the trusted identity and partition headers
consumed by the API.
- Line 80: Update the “Client credential lifecycle” section to define the remote
applier’s projected-token mount, token file reload behavior after tokenCacheTtl,
and/or TokenRequest renewal policy. Ensure the contract requires refreshing
credentials before expiry so desire reads and status writes continue
functioning.

In `@hyperfleet/adrs/0022-api-mediated-desire-store-access.md`:
- Line 19: Update the API configuration and startup path so tenant enforcement
is mandatory rather than conditional on config.server.tenant.enabled, and
require a partition dimension for every request. Ensure the service rejects
startup or requests when tenant context is unavailable, preventing unscoped
data-layer queries; if an equivalent mandatory server-side isolation control
already exists, enforce and document it instead.

Nice job condensing this, the ADR reads well and the direction is settled as far as I'm concerned. Rafael's threads are closed out too.
Follow up design ticket is up: HYPERFLEET-1645. That's where the cross cluster identity, partition binding, existing API vs dedicated service, REST vs gRPC, gateway load and the two diagrams land, so none of that needs to be answered here. It'd be worth pointing the spike's open questions section at it so Rafael's tracking ask is closed off.
Left three comments on the ADR, nothing blocking, mostly making sure the ADR doesn't read as more settled than it is.
