PROJECT TERMINOLOGY
Stripe API - Tide Casa service billing: Quotes, setup/maintenance subscription checkout, invoices, cancel/discard and guest purchase contracts. ServiceBillingProvider supports sandbox or explicitly gated live configuration; creation requires checkout/cards-only/method configuration gates. Webhook signature verification and invoice/refund reconciliation code exists.

MJos Predictive Model: umbrella project and first manifestation of the Bangel Language in this edition.
Bangel Language: typed expression layer.
Elsa: compiler.
JP: independently admitted representation; preserve its actual versioned protocol.
Joanna: runtime and execution evidence.
MJ: separate permission and resource authority.
UNKNOWN: unavailable or unsupported value, never numerical zero.

PROJECT TYPES
- BillingEnvironment: sandbox | live
- Quote: initial + monthly + currency + fingerprint + terms version
- SubscriptionState: provider-bound
- InvoiceEvidence: amount + paid/refunded state

PROFILE RULE
Keep case-sensitive neural r0/r9 distinct from uppercase R-state semantics. Historical MJ-PBMEF build IDs are provenance, not current company branding. Existing evidence profiles retain their source-specific meanings.

EVIDENCE LIMITS
- Distinct from merchant payments, which are currently test-only.
- Source ability to configure live is not evidence live billing is activated.
- No subscriptions were created or changed.

Publication is pending owner review. White papers are excluded.
