+# SQL Migrations
+
+Incremental schema changes applied in order by timestamp prefix.
+
+## Naming Convention
+
+Migration directories follow the format:
+
+```
+YYYY-MM-DD-HHMMSS-NNNN_description_goes_here/
+  up.sql
+  down.sql
+```
+
+These are created with the `diesel` tool, and in particular:
+
+> `diesel migration generate description_goes_here`
+
+- `NNNN` is a zero-padded sequence number for ordering multiple migrations on the same timestamp.
+- `up.sql` applies the migration forward.
+- `down.sql` reverses it.
+
+## Table Conventions
+
+- Primary key `id` columns must be `BIGINT(20) UNSIGNED NOT NULL AUTO_INCREMENT`. Do not use signed IDs.
+- Always create tables with `ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin`.
+- All SQL files should start with the standard IntelliJ noinspection comments:
+  ```sql
+  -- noinspection SqlDialectInspectionForFile
+  -- noinspection SqlNoDataSourceInspectionForFile
+  -- noinspection SqlResolveForFile
+  ```
+
+## Rules
+
+- Every `up.sql` must have a corresponding `down.sql` that cleanly reverses the migration.
+- For `CREATE TABLE` migrations, the `down.sql` is typically `DROP TABLE IF EXISTS table_name;`.
+- For `ALTER TABLE` migrations, the `down.sql` reverses the alteration (e.g. `DROP COLUMN`).

+# Squashed / Materialized Schemas
+
+Fully materialized table definitions representing the current state of each table
+after all migrations have been applied. These are not executed — they exist as
+human-readable documentation of the current schema.
+
+## When to Update
+
+Update the corresponding squashed file whenever a migration changes a table's schema
+(adding columns, changing types, dropping and recreating, etc.).
+
+## Table Conventions
+
+- Primary key `id` columns must be `BIGINT(20) UNSIGNED NOT NULL AUTO_INCREMENT`. Do not use signed IDs.
+- Always create tables with `ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin`.

+  -- noinspection SqlDialectInspectionForFile
+  -- noinspection SqlNoDataSourceInspectionForFile
+  -- noinspection SqlResolveForFile
+  ```
+
+## File Organization
+
+Files are named after their table (e.g. `users.sql`, `media_files.sql`).
+Some tables are grouped into subdirectories (e.g. `user_tables/`).
