9.3 — Transactional reminders

[tessak22]

Summary

The time-sensitive per-cow reminders around breeding and calving.

Spec references

• §5.7 (message catalog), §10b (Cattle status)

Requirements

• Schedule reminders off breeding + calving dates (from preg-check/gestation).

Acceptance criteria

• Around a breeding: Insem +21d (watch for return-to-heat), +30d (book preg check), +60d if no preg check booked (§5.7).
• Calving countdown: Due −4wk / −2wk / −5d / −2d / −1d + offer assistance; due-date-passed care check (§5.7).
• Countdown fires only after a final bred preg-check result (7.3) and uses the due date from 1.4.
• Marking the animal inactive STOPS all its pending reminders immediately (§10b, 4.1).
• These are category 1/3 messages; channel resolved via 9.2.

Config over code

Offsets/templates as data/config; due date via gestation_config.

Tests

• bred result schedules the countdown set; inactivating the cow cancels them.
• +21/+30/+60 scheduled from insemination date.

Definition of done

Breeding + calving transactional reminders; inactivation cancels; gated on final results.
