# RAIL-FAB-WP-0028 - Hosted financial Fabric authority
|
|
|
|
## Goal
|
|
|
|
Turn the local registry-backed authority proven by FIN-WP-0003 and
|
|
STATE-WP-0079-D2 into a durable production owner surface. State Hub can retain
|
|
an immutable projection during the strangler window, but retirement must not
|
|
depend on a workstation process or a workstation-owned SQLite database.
|
|
|
|
Origin: residual from `STATE-WP-0079-T04` after the 2026-08-31 D2 parity and
|
|
rollback rehearsal.
|
|
|
|
## T01 - Decide runtime and persistence ownership
|
|
|
|
```task
|
|
id: RAIL-FAB-WP-0028-T01
|
|
status: todo
|
|
priority: high
|
|
state_hub_task_id: "65702f41-b87e-59e5-9396-cd1fda5e8ef4"
|
|
```
|
|
|
|
Select the production runtime, persistent registry store, backup/restore
|
|
boundary, authentication policy, and deployment repository. Preserve accepted
|
|
snapshot history and deterministic snapshot-set provenance.
|
|
|
|
## T02 - Deploy the authority service
|
|
|
|
```task
|
|
id: RAIL-FAB-WP-0028-T02
|
|
status: wait
|
|
priority: high
|
|
state_hub_task_id: "cad1af1d-177b-5a47-a9fa-d99c40bb2649"
|
|
```
|
|
|
|
Package and deploy the registry service with health/readiness checks and stable
|
|
owner endpoints for `/exports/financial`, `/graph/summary`, and `/graph/edges`.
|
|
Do not expose mutation endpoints without the authorization selected in T01.
|
|
|
|
## T03 - Automate freshness and recovery
|
|
|
|
```task
|
|
id: RAIL-FAB-WP-0028-T03
|
|
status: wait
|
|
priority: high
|
|
state_hub_task_id: "78a73d4e-46aa-53c7-911b-be5f79bc25e8"
|
|
```
|
|
|
|
Run a reviewed accepted-snapshot refresh loop, surface stale/error state, and
|
|
prove backup/restore without changing the deterministic export for an unchanged
|
|
accepted snapshot set.
|
|
|
|
## T04 - Cut direct consumers over
|
|
|
|
```task
|
|
id: RAIL-FAB-WP-0028-T04
|
|
status: wait
|
|
priority: high
|
|
state_hub_task_id: "c66c3fa4-8856-5999-8c47-dbb2f6efc21e"
|
|
```
|
|
|
|
Run the fin-hub consumer gate against the hosted owner endpoint, inventory and
|
|
switch any real callers, exercise rollback, and hand the receipts back to
|
|
`STATE-WP-0079-T04` before State Hub's Fabric projection routes retire.
