Replace pre-aggregated costs.json with expense_records.json (48 line-item
records) and payment_records.json. All monthly and cumulative totals are
computed deterministically in observatory/ledger.py. Correct Bubble.io to
$32/mo (since Feb 2025) — infrastructure €69.44/mo not €72.20.
Split infrastructure vs payment-processing costs. Liquidity burn now
uses infrastructure cash out only (€1,155.20 cumulative) because Stripe
fees are already deducted from net member payments. Total platform cost
(€1,158.24) remains visible for gross-margin economics.
Restore operator platform costs (Bubble, domains, Stripe) with monthly
history from March 2025 and member payments from November 2025. Track
€1,000 starting budget, cumulative burn, and remaining liquidity in the
economics dashboard. Document LQ requirements in REQUIREMENTS.md.
