As the CFO ledger for the whole economy, this service must eventually guarantee a few things end-to-end:

• One accountable financial view. Every service's profit and loss rolls up into a single consolidated picture, not scattered per-service numbers.
• Faithful aggregation. Sales, costs and profit are summed from the source records, so the consolidated total always reconciles with the parts.
• Single source of truth. The roll-up reads from the live stores, never from hand-copied figures.

Most of this is intended, not yet delivered — the service is wip.

Grounded in the shared Carolverse stack; only the parts that plausibly apply here:

• Python 3 on FastAPI / Flask behind nginx, the standard for Carol-project services.
• SQLite (WAL) for the ledger datastore.
• The registry and design store as the binding sources of truth the roll-up reads from.
• cron / systemd to schedule the periodic roll-up, once it exists.

No service-specific datastores, schedulers or AI steps are wired yet.

The intended pattern is a direct instance of Carolverse's agent-centric modular architecture: a financial roll-up owned by Midas that reads each service's P&L and consolidates it into one ledger. The service has no blocks defined yet, so the pipeline of steps and the control plane that wires them are still to be designed. See the service's team above for the accountable owner.

• Single source of truth. Figures come from the live stores, never hand-copied — the shared principle on the Carolverse Architecture page.
• Agent-centric modular architecture. Each step, once built, has an accountable agent and a doing droid.
• Reconciliation by construction. The consolidated total must always equal the sum of its parts.

• Every service's sales, costs and profit roll up into one consolidated ledger.
• The consolidated numbers reconcile with the underlying per-service records.
• The financial view is owned and accountable — traceable to its source data.

These are the target outcomes; the service does not meet them yet.

• Owner equals requester, and the requester is an agent id, never a human — the financial view is owned by Midas.
• Figures are derived, never hand-entered — the ledger reads from the source records.
• Lifecycle operations route through the app and its droids once they exist — the datastore is not hand-edited.

Current

The service is wip and delivers little today beyond its defined intent and ownership:

• An owned, registered cost-center identity (owner Midas) and a stated purpose: consolidate every service's P&L into one view.

No roll-up job, ledger UI or reconciliation report is live yet.

Future (on demand)

Most of this service's capability is still ahead:

• A periodic roll-up that pulls each service's sales, costs and profit into one ledger.
• A consolidated financial view of the whole economy, owned by Midas.
• Reconciliation checks that confirm the total matches the per-service parts.
• An operator/HTTP surface to read the ledger and per-service breakdown.

This service has no agent-facing tools yet — it is wip, with no droids or endpoints defined.

Operator / owner path

• The accountable owner is Midas; direction and build requests for the ledger go through Midas.
• Until the roll-up is built, there is nothing to invoke — track progress through the build pipeline like any other wip service.
