Architecture

The flow is RFP (seeded, status overlay) → quote build (room subtotal = BAR × rooms × nights × (1 − negotiated%) + event-space day rate × nights + 12% tax + narrative) → send (simulated email) → confirm (group booking + invoice + optional corporate account) or decline. The quote draft is a deterministic template composer — no model call.

Reads shared property / room_type / rate_plan and the foundation guest. Writes its own C4 overlay — RFP status, quotes, group bookings, corporate accounts — held per credential in the C4Store scope, plus a mirrored shared-core booking on confirmation. In Stage-2 these map to demo_eco_* RFP/quote/group/corporate tables, with the core booking written via C4Sinks.coreBooking. The data invariant holds: owner writes canonical; a viewer's RFP/quote/group writes are credential-scoped, ephemeral, reset-clearing.

Emits quote.sent (send), group.booked + booking.created (confirm) and corporate.created (new company); uses the host notification for the simulated quote email (the #34/#35 send path). Metered AI: none — the rfp-read→quote-draft stage records a $0 cost_ledger row labelled 'deterministic (rules · $0)'; there is no demo_cache. Honesty is inspector-only (plus the on-surface AI-assist-draft/simulated badge).

No real quote-drafting LLM, no real email delivery (the quote lands in the in-app sent viewer), and no real invoicing/payment rail — settlement belongs to the simulated Payments & Partner Settlements #34 in a later cluster. No real imagery, no PII, no proprietary metrics appear anywhere.
