Add or change a database schema in a PROMPT 2.0 Go service using golang-migrate + sqlc — write the migration and queries, regenerate type-safe Go, and stay green on the migration CI check. Use when adding a table/column, writing SQL queries, or running sqlc.

1. Write the migration

Migrations are in servers/<service>/db/migration/, numbered sequentially: NNNN_short_description.up.sql (zero-padded 4 digits, next number after the highest existing one).
Down migrations are OPTIONAL and inconsistent across services — only add a matching NNNN_short_description.down.sql if that service already ships .down.sql files (ls servers/<service>/db/migration/*.down.sql). If it doesn't, stay up-only to match convention.
Keep one logical change per migration; never edit an already-merged migration — add a new one.

2. Write queries

Add/extend SQL in servers/<service>/db/query/*.sql with sqlc annotations, e.g.:
```
-- name: GetTutors :many
SELECT * FROM tutors WHERE course_phase_id = $1;
```
Use :one, :many, :exec, :execrows as appropriate.

3. Regenerate Go

From servers/<service>/: sqlc generate (config in sqlc.yaml; output lands in db/sqlc/, package db, pgx/v5). Or make sqlc-<service> from the repo root.

Use generated methods in services:

import db "github.com/prompt-edu/prompt/servers/<service>/db/sqlc"
tutors, err := queries.GetTutors(ctx, coursePhaseID)

4. Verify (matches CI)

cd servers/<service> && go build ./... && go test ./... (tests use testcontainers-go).
The detect-migrations.yml workflow flags migration changes — ensure new files follow the NNNN_*.up.sql naming and that db/sqlc/ was regenerated and committed alongside the migration.
Never commit a migration without its regenerated db/sqlc/ changes.
