Fix CPM hallucination: pricing_type enum + quote validation#7
Conversation
Sellers can now express whether a price is fixed, a floor for negotiation, or unavailable (rate on request). This is the foundation for preventing buyer agent CPM hallucination -- when pricing_type=on_request, pricing fields are None and buyer agents must negotiate rather than fabricate numbers. Changes: - New models/pricing_type.py with PricingType(fixed|floor|on_request) - ProductDefinition: add pricing_type, make base_cpm/floor_cpm Optional - Package: add pricing_type, make base_price/floor_price Optional - QuotePricing: add pricing_type, make base_cpm Optional - Pricing (core): add pricing_type - All default to FIXED for backward compatibility - 18 new tests covering all models and backward compat bead: ar-7rgy Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Records every quote the seller issues to quote_history storage and cross-references incoming buyer proposals against that history. Proposals with CPMs that don't match any active quote are flagged as pricing_verified=false (not rejected — flagged for review). - QuoteHistoryStore: record/find/verify quotes with 1% tolerance - create_quote endpoint: persists to quote_history on issue - submit_proposal endpoint: runs pricing verification, returns result - ProposalResponse: new pricing_verified + pricing_verification_reason - ProposalEvaluation: new pricing_verified field - 10 new tests (9 unit + 1 integration-level) bead: ar-hm9l Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
