# validatord smoke — Phase 43 PRD parity acceptance gate.
#
# Validates:
#   - validatord boots, reports /health
#   - POST /v1/validate with kind=playbook returns 200 + Report on
#     well-formed input
#   - POST /v1/validate with kind=playbook returns 422 + ValidationError
#     when fingerprint is missing
#   - POST /v1/validate with kind=fill consults the JSONL roster
#     (phantom candidate → 422 Consistency)
#   - POST /v1/validate with unknown kind returns 400
#   - All assertions go through gateway :3110 (proxy correct)
#
# Doesn't exercise /iterate — that needs a live chat backend, covered
# by cmd/validatord/main_test.go's fakeChatd helper. CI-friendly.
#
# Usage: ./scripts/validatord_smoke.sh
