# STATE-WP-0051 - Financial Fabric Read Model Adaptation
|
||||
|
||||
## Goal
|
||||
|
||||
Adapt State Hub's Railiance Fabric read model to the improved Fabric intent:
|
||||
financial fabric boundaries, king/lord/tenant ownership, fabric and subfabric
|
||||
containment, cross-boundary utility interfaces, and optional cost/profit center
|
||||
views.
|
||||
|
||||
State Hub remains a read/cache/query surface. `railiance-fabric` remains the
|
||||
source of truth for Fabric graph discovery, normalization, versioning, and
|
||||
exports.
|
||||
|
||||
## Background
|
||||
|
||||
`STATE-WP-0050` added the first State Hub ingest/read model for
|
||||
`railiance-fabric` graph exports. That implementation matches the
|
||||
post-`RAIL-FAB-WP-0016` canon-aligned export.
|
||||
|
||||
The Fabric intent has now shifted away from repo-owned external declarations
|
||||
toward durable infrastructure-responsibility boundaries:
|
||||
|
||||
- the king is responsible for the netkingdom and holds relevant recovery,
|
||||
secrets, and backup authority;
|
||||
- lords pay for fabrics;
|
||||
- tenants pay for restricted subfabric utility;
|
||||
- every graph node needs resolvable ownership;
|
||||
- cross-boundary utility edges are first-class value interfaces;
|
||||
- cost/profit centers are optional accounting attributions and view dimensions;
|
||||
- security-zone concepts such as realm and domain are intentionally not core
|
||||
Fabric concepts.
|
||||
|
||||
This workplan adapts State Hub to import, query, and display the vNext Fabric
|
||||
contract developed by `RAIL-FAB-WP-0017` and populated by `RAIL-FAB-WP-0018`.
|
||||
|
||||
## T01 - Align With The VNext Fabric Export Contract
|
||||
|
||||
```task
|
||||
id: STATE-WP-0051-T01
|
||||
status: todo
|
||||
priority: high
|
||||
state_hub_task_id: "cf39a822-81ec-4834-9b95-b8013ccc1434"
|
||||
```
|
||||
|
||||
Review and align with the vNext Fabric export contract from
|
||||
`RAIL-FAB-WP-0017`.
|
||||
|
||||
Requirements:
|
||||
|
||||
- identify new export fields for fabric/subfabric containment;
|
||||
- identify owner actor fields and king/lord/tenant roles;
|
||||
- identify cross-boundary utility edge metadata;
|
||||
- identify cost/profit center attribution fields;
|
||||
- identify schema/export version metadata;
|
||||
- decide backward compatibility behavior for existing `STATE-WP-0050` imports.
|
||||
|
||||
Done when:
|
||||
|
||||
- State Hub has an implementation checklist for the new export shape;
|
||||
- compatibility and migration behavior are explicit;
|
||||
- blocking questions are fed back to `railiance-fabric` if the export contract
|
||||
is incomplete.
|
||||
|
||||
## T02 - Extend Read-Model Storage
|
||||
|
||||
```task
|
||||
id: STATE-WP-0051-T02
|
||||
status: todo
|
||||
priority: high
|
||||
state_hub_task_id: "989387ff-5c70-4eb4-a418-fd61e2a664dd"
|
||||
```
|
||||
|
||||
Extend State Hub storage for the improved Fabric graph read model.
|
||||
|
||||
Requirements:
|
||||
|
||||
- preserve import metadata and idempotency from `STATE-WP-0050`;
|
||||
- store export schema/version metadata;
|
||||
- store fabric and subfabric identity on nodes and edges;
|
||||
- store owner actor identity and owner role;
|
||||
- store cross-boundary utility metadata;
|
||||
- store node and edge cost/profit center attribution when present;
|
||||
- preserve raw payloads for audit/debugging;
|
||||
- avoid treating imported Fabric graph rows as State Hub-authored work items.
|
||||
|
||||
Done when:
|
||||
|
||||
- migrations and repository/service helpers exist;
|
||||
- old imports remain readable or are intentionally reset with documentation;
|
||||
- latest-import behavior still works.
|
||||
|
||||
## T03 - Update Ingest And Validation
|
||||
|
||||
```task
|
||||
id: STATE-WP-0051-T03
|
||||
status: todo
|
||||
priority: high
|
||||
state_hub_task_id: "97c40d3c-33dd-4848-b375-4302811c0319"
|
||||
```
|
||||
|
||||
Update Fabric graph ingest to accept and validate the vNext export payload.
|
||||
|
||||
Requirements:
|
||||
|
||||
- validate required ownership and fabric/subfabric fields according to the
|
||||
export contract;
|
||||
- preserve incomplete/unresolved markers from Fabric rather than inventing
|
||||
State Hub ownership;
|
||||
- ingest cross-boundary utility edges without flattening their business meaning;
|
||||
- ingest cost/profit center attribution as optional accounting metadata;
|
||||
- record failed validation in normal import/progress surfaces;
|
||||
- keep pull mode from the Fabric registry.
|
||||
|
||||
Done when:
|
||||
|
||||
- direct ingest and pull ingest work for vNext exports;
|
||||
- malformed exports fail without partially mutating the read model;
|
||||
- repeated vNext imports remain idempotent.
|
||||
|
||||
## T04 - Add Query Surfaces And Views
|
||||
|
||||
```task
|
||||
id: STATE-WP-0051-T04
|
||||
status: todo
|
||||
priority: medium
|
||||
state_hub_task_id: "64b0d9d2-bcfc-498f-b9b5-cbbcd3c26ead"
|
||||
```
|
||||
|
||||
Expose read-only query surfaces for the improved Fabric model.
|
||||
|
||||
Queries should support filtering or summarizing by:
|
||||
|
||||
- fabric;
|
||||
- subfabric;
|
||||
- owner actor;
|
||||
- owner role: king, lord, tenant, operator/steward where present;
|
||||
- cross-boundary utility edges;
|
||||
- provider owner and consumer owner;
|
||||
- cost center;
|
||||
- profit center;
|
||||
- unresolved ownership;
|
||||
- unresolved accounting attribution;
|
||||
- source repo and canonical metadata retained from the previous model.
|
||||
|
||||
Done when:
|
||||
|
||||
- API endpoints can answer the primary architecture questions;
|
||||
- existing `/fabric/graph/*` endpoints are extended or versioned cleanly;
|
||||
- no query mutates State Hub workstreams, tasks, messages, decisions, or
|
||||
progress rows.
|
||||
|
||||
## T05 - Add Dashboard/Operator Readiness
|
||||
|
||||
```task
|
||||
id: STATE-WP-0051-T05
|
||||
status: todo
|
||||
priority: medium
|
||||
state_hub_task_id: "852ac7b6-9296-4900-a34d-3e8ed2983237"
|
||||
```
|
||||
|
||||
Prepare State Hub surfaces for operator use.
|
||||
|
||||
Useful summaries:
|
||||
|
||||
- node counts by fabric and subfabric;
|
||||
- nodes by owner and owner role;
|
||||
- cross-boundary utility edges by provider and consumer;
|
||||
- tenant-facing utilities without payment schema;
|
||||
- owned nodes without cost/profit center attribution;
|
||||
- unresolved ownership or containment gaps;
|
||||
- latest import freshness and schema version.
|
||||
|
||||
Done when:
|
||||
|
||||
- API summaries are dashboard-ready;
|
||||
- docs include operator examples;
|
||||
- the UI or documented API flow makes it clear that State Hub is displaying a
|
||||
Fabric read model, not authoring topology.
|
||||
|
||||
## T06 - Verify Against A Rebuilt Railiance Baseline
|
||||
|
||||
```task
|
||||
id: STATE-WP-0051-T06
|
||||
status: todo
|
||||
priority: high
|
||||
state_hub_task_id: "6bee7960-4714-4278-80fc-f8e32ec203bc"
|
||||
```
|
||||
|
||||
Verify the State Hub adaptation against the rebuilt Railiance Fabric baseline
|
||||
from `RAIL-FAB-WP-0018`.
|
||||
|
||||
Requirements:
|
||||
|
||||
- import a vNext export from `railiance-fabric`;
|
||||
- verify fabric/subfabric, ownership, cross-boundary utility, and accounting
|
||||
fields are stored and queryable;
|
||||
- verify old read-model behavior that remains supported;
|
||||
- add regression tests for validation failure, idempotent import, latest import
|
||||
selection, and read-only query behavior;
|
||||
- document refresh commands for operators.
|
||||
|
||||
Done when:
|
||||
|
||||
- State Hub can import and query the improved Fabric export;
|
||||
- tests cover the new fields and compatibility behavior;
|
||||
- operator docs explain how to refresh after a Fabric rebuild.
|
||||
|
||||
## Acceptance
|
||||
|
||||
- State Hub imports the vNext Fabric graph export as a read model only.
|
||||
- Fabric/subfabric containment and owner actor data are stored and queryable.
|
||||
- Cross-boundary utility interfaces can be queried as value interfaces.
|
||||
- Cost/profit center attribution is queryable as accounting/view metadata.
|
||||
- State Hub does not redefine Fabric boundaries or invent ownership.
|
||||
- Regression tests cover ingest, validation, idempotency, latest import, and
|
||||
read-only query behavior.
