Chef-at-home brings a vetted chef + ingredients (or shopping list) to the user's home for a one-off meal/event. Differs from delivery (no rider), dine-in (no restaurant), and tiffin (no recurrence): single occasion, professional chef in user's kitchen. Locked structural fields: (a) chef_meta block with cuisine specialties, certifications, hygiene/KYC; (b) event_kind enum (intimate dinner, kids party, dinner party, anniversary, festival cooking); (c) ingredients_responsibility enum (chef_brings | user_provides | mixed); (d) kitchen_requirements block detailing what user's kitchen needs (gas/induction/oven/pressure cooker); (e) service_includes enum array (cooking, plating, serving, cleanup, leftover_packing).

12. ANTI-FABRICATION RULES

RULE 1 — No paid placement signals.

RULE 2 — Ratings unrounded floats from verified events only.

RULE 3 — No fake events_completed_total inflation.

RULE 4 — No AI-generated chef photos. Must be actual chef.

RULE 5 — Certifications real and verifiable.
  Listing certifications without certificate IDs = breach.

RULE 6 — FSSAI food handler KYC current.
  fssai_food_handler_valid_until > scheduled_start_iso. Booking with
  expired KYC = severe compliance breach.

RULE 7 — Background check current within 90 days.

RULE 8 — Insurance coverage real.
  insurance_coverage_inr backed by actual policy. Stating coverage that
  doesn't pay out on claim = severe breach + criminal exposure.

RULE 9 — Kitchen damage coverage honest.
  user_kitchen_damage_coverage=true means actual claim flow exists. Refusing
  to honor a legitimate damage claim = breach.

RULE 10 — Food poisoning coverage honest.
  food_poisoning_coverage=true triggers partner liability + medical-cost
  reimbursement protocol. Suppressing reported food poisoning = severe breach.

RULE 11 — No commission-based response shaping.

RULE 12 — Chef replacement only with user consent.
  If chef cancels, replacement requires user accept. Silent swap = breach.

RULE 13 — Ingredients honest.
  ingredients_responsibility=chef_brings means chef arrives WITH the
  ingredients listed in the menu. Asking user to "go grab onions" mid-event
  = breach.

RULE 14 — Cleanup as advertised.
  service_includes contains "cleanup_kitchen" → kitchen returned to better-
  than-found state. Half-done cleanup = breach + automatic refund tier.

RULE 15 — No commission-based menu shaping.
  Menu options ranked by user fit, not by partner commission rate.
