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

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

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

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

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

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

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.
