# Fin Hub
|
||
|
||
Resource viability hub for the FOS federation — budgets, commitments, burn rate,
|
||
runway projection, and token spend tracking.
|
||
|
||
Fin-hub extends `hub-core` with financial models and read surfaces. Generic hub
|
||
primitives (domains, repos, messages, progress events) come from hub-core;
|
||
fin-specific models (budget, commitment, burn rate, runway, token spend) live
|
||
here.
|
||
|
||
## Status
|
||
|
||
MVP complete (`CUST-WP-0025` T22–T26): models, CSV ingest, runway CLI, FOS
|
||
coupling, RaaS packaging draft. Operational hardening tracked in
|
||
`workplans/FIN-WP-0001-runway-operations-lane.md`.
|
||
|
||
## Quick Start
|
||
|
||
```bash
|
||
cd /home/worsch/fin-hub
|
||
uv sync
|
||
uv run pytest
|
||
uv run finhub runway --balance 12000 --monthly-burn 2100,2200,2000
|
||
uv run finhub ledger import cloud tests/fixtures/cloud-costs.csv
|
||
uv run finhub ledger set-price --client acme --application portal --instance prod-01 --period 2026-07 --amount 100 --source agreement-2026-01
|
||
uv run finhub ledger margins
|
||
uv run finhub evaluate
|
||
uv run finhub evidence --seed-fixtures
|
||
uv run finhub serve
|
||
uv run finhub import-cloud tests/fixtures/cloud-costs.csv
|
||
uv run finhub ops-costs tests/fixtures/hosteurope.csv
|
||
```
|
||
|
||
Cross-hub coupling (`--emit`) posts non-secret progress events to dev-hub when
|
||
`STATE_HUB_API` is reachable.
|
||
|
||
## Client cost attribution
|
||
|
||
HostEurope CSV rows may include `client_id`, `application_id`, and
|
||
`app_instance_id`. All three must be present together. Fin-hub validates them
|
||
as external identifiers and derives the stable key
|
||
`client:<client_id>|app:<application_id>|instance:<app_instance_id>`; callers
|
||
must not invent a second key format. Rows without all three columns remain
|
||
explicitly unattributed for backward compatibility.
|
||
|
||
The SQLite ledger adds the attribution columns automatically when an existing
|
||
ledger is opened. The `ops-costs` report retains its per-service view and adds
|
||
an `attributions` view separated by currency. Client and application identity
|
||
remain authoritative outside fin-hub.
|
||
|
||
Engagement prices are reporting entitlements, not invoices or received
|
||
payments. A price is identified by client/application/instance, reporting
|
||
month, and currency. Corrections are append-only: pass the current record ID
|
||
to `ledger set-price --revision-of`; margin reports use the newest revision
|
||
and preserve the earlier price for auditability.
