Start ledger January 2025. Record coulomb.social (3.75 EUR/mo) and coulomb.pro (3.00 EUR/mo) as per-domain expense rows. Remove Bubble and placeholder overhead. Add infrastructure reference catalogs; virtual server records pending invoice data.
Coulomb Pricing (MVP)
Project-specific material for the Coulomb Social Economic Observatory MVP.
Generic adaptive-pricing framework concepts belong in the repository root
(INTENT.md, docs/, research/, registry/). Execution tracking:
workplans/ADAPTIVE-WP-0002-economic-observatory-mvp.md.
Liquidity and cost requirements: REQUIREMENTS.md.
Sprint 1 — Economic Foundations
The observatory/ package reads expense and payment record ledgers and
computes all totals programmatically (ledger.py → economics.py).
| Ledger | File |
|---|---|
| Budget (€1,000 start) | data/budget.json |
| Expense records | data/expense_records.json |
| Payment records | data/payment_records.json |
| Product model | data/product.json |
| Pricing models | data/pricing-models.json |
| Membership | data/membership.json |
Current reality: infrastructure from January 2025 — domains €6.75/mo
(coulomb.social €3.75 + coulomb.pro €3.00, per registrar invoices). Virtual
server records pending. Sole member payments from November 2025. Customer
cost-pass-through billing is not active.

Manual ledgers will be replaced by Bubble (Sprint 2), Stripe (Sprint 3), and OpenRouter (Sprint 4) importers.
