# 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:** platform costs from March 2025 (Bubble.io **$32/mo** since
Feb 2025); sole member payments from November 2025. Operator is **burning
liquidity**. Customer cost-pass-through billing is not active.
### Commands
```bash
cd projects/coulomb-pricing
python3 -m pytest -q
python3 -m observatory --period 2026-06
python3 -m observatory --period 2026-06 --output reports/economics-2026-06.md
```
Manual ledgers will be replaced by Bubble (Sprint 2), Stripe (Sprint 3), and
OpenRouter (Sprint 4) importers.
