-- 0005_jobs_init_kind.sql
--
-- Add 'init' to the jobs.kind CHECK constraint so the operator can
-- dispatch a `restic init` job from the UI before the first backup.
-- SQLite can't ALTER a CHECK in place, so we rebuild the table.
--
-- Rebuild pattern note: we create jobs_new (with the wider CHECK),
-- copy data over, DROP the original jobs table, then ALTER RENAME
-- jobs_new TO jobs. This avoids the trap of renaming the original
-- first — with legacy_alter_table=OFF (the modern default), a rename
-- propagates into FK references in dependent tables (e.g.
-- job_logs.job_id), leaving them pointing at the temporary name even
-- after we drop it. Migration 0006 cleans up the orphan FK left by
-- the first version of this migration on already-affected DBs.
