A person's whole 'which doctor' history was one free-text column on a reminder: they typed the practice name once and could reach nothing else that happened there. This turns that string into a record. Five tables in migration 0320, all additive: an encounter that happened or is booked, the account's own address book of practitioners, and three links from a visit to the documents, lab results and conditions it produced. The encounter is slim on purpose — the diagnosis stays on the linked condition, the address on the linked practitioner, and the reason each field was kept or cut is written at the model. No module gate, and the schema says why rather than leaving the absence to be read as an oversight. Every carrier lands with the tables rather than after them. All five are classified as travelling both ways and are proven doing it: a seeded row of each goes out through the real export builder, the account is deleted so the schema's cascade decides what survives, and the rows are counted back through the real restore route. Two references deliberately do not survive and are named instead of dropped quietly — the reminder a visit points at is not in the backup, and a link whose far side a portable export does not carry cannot resolve. The wipe plan deletes the links before the lab results and documents they hang off, or the audit row would report zero for rows that existed. The three encrypted columns are registered for key rotation, without which dropping a legacy key would make those notes permanently unreadable. Widening the reminder origin enum is a type error at the reminder DTO, which is the right outcome: the mapper now refuses an appointment row outright rather than relabelling it as a checkup.
