"description": "Calculates a construction material supplier's preliminary notice and lien filing deadlines from delivery events (contract supplier-events-v2), for questions that need deadline dates. Available baselines cover Florida and Kansas private projects; other states and public projects return review_required, which is a valid result, not an error. How the parameters depend on each other: last_delivery_date is required when deliveries_complete is true. Florida (FL) takes florida_final_payment_status and florida_termination_status; Kansas (KS) takes kansas_extension_status; these are rejected for other states. Each takes yes, no or unknown: an omitted or unknown answer keeps the affected deadline under review, and a blanket review flag is not accepted. The Florida final-payment answer holds the notice for suppliers not hired by the owner. A Florida event date is accepted only with the matching yes answer. Delivery dates are furnishing dates, not invoice dates. Returns JSON with an overall status (calculated or review_required), preliminary_notice and lien_filing (each with its own status: calculated, not_required, review_required or awaiting_final_delivery, plus deadline, days_from_now, description and statute source_url), critical_warnings, statute_citations, an exact echo of the submitted inputs and a disclaimer. Invalid or contradictory facts return an error naming the field before any API call. Requires a customer key and consumes one plan calculation unit. No project is saved, notice sent or lien filed. Not legal advice.",

"description": "Evaluates supplier-events-v3 project facts against the exact discovered rule and question identities. Returns independent notice and lien outcomes with sources and an exact nested input echo. When RI discovery asks ri_mailed_within_200_days after ri_mailed=yes, confirm whether mailing occurred within 200 days of first delivery. No, Unknown or omitted confirmation requires review; recording alone does not establish a 40-day target. Only calculated outcomes contain calculated deadline dates. Report every candidate_deadlines entry with its ID, date and sources under the API explanation. For NH review fallbacks, first_furnishing is a conservative checkpoint and final_furnishing is informational pending contract grouping and qualifying completion; passing the first checkpoint does not itself establish expiry. A calculated contract_completion outcome uses only the returned deadline, without substituting the first checkpoint or recomputing a date. Review candidates do not establish filing deadlines, completion or scheduled reminders. An optional preliminary_notice.notice_duties collection contains independently required named notices, each with its own calculated date, explanation and sources; the legacy preliminary date is only their earliest summary. Report every validated duty without inferring duties from candidates or treating one notice as satisfying all duties. A separate optional preliminary_notice.planned_notice_targets collection contains qualified intent planning targets with their target dates, assumed filing dates, full ten- or thirty-day intervals, explanations and sources. Planning targets do not establish statutory expirations, actual filing, notice completion or scheduled notifications. An optional verified action_by is a Conservative action date planning target under qualified review; the statutory deadline and countdown remain unresolved, with explanation, sources and warnings. Optional recurring_notice_facts supplies actual Tennessee furnished months or New Hampshire account records. Tennessee recurring_notice_periods cover entered periods only, including paid and unknown states; known unpaid duties remain independent. New Hampshire recurring_notice_checkpoints are advisory check-ins with unresolved legal status, not legal deadlines, service, completion or scheduled reminders; they do not reset earlier gaps. Never infer intervening months or blanket completion. Stale identities return 409, unavailable reviewed sources return 503. Requires a customer key and consumes one plan calculation unit. No project is saved, notice sent or lien filed.",
