-- Base schema snapshot: the database shape immediately BEFORE migration 0009.
--
-- This file exists solely to feed TestSchemaMatchesMigrations. Applying this
-- file and then running every migration in migrations/ must produce the same
-- schema as applying schema.sql directly. That is the invariant the test
-- enforces, and it is what keeps schema.sql and the migrations in lockstep.
--
-- HOW THIS WAS DERIVED
--
-- Not from history. It was reconstructed by taking the current schema.sql and
-- reversing migrations 0029 down to 0009:
--
--   0029  drop stripe_processed_events
--   0028  drop devices.secret_lookup and its index
--   0027  drop users.registry_domain
--   0026  drop webhooks.last_fired_at
--   0025  drop taken_down_subjects and labeler_cursor
--   0023  (labels table is created by 0023 and dropped by 0025: absent here)
--   0022  drop jetstream_cursor
--   0021  drop repository_stats_daily
--   0020  drop manifests.subject_digest and its index
--   0019  drop advisor_suggestions
--   0018  drop users.oci_client
--   0017  drop repo_pages.user_edited
--   0015  drop webhooks and scans
--   0014  drop users.default_hold_did
--         (hold_captain_records.supporter_badge_tiers is added by 0014 and
--          dropped by 0016, so it nets out and is absent here)
--   0013  drop crypto_keys
--   0012  drop layers.annotations
--   0011  hold_captain_records is rebuilt by 0011; 0010 added successor, so
--         the pre-0010 table has neither successor nor supporter_badge_tiers
--   0009  restore the 11 dead columns on manifests that 0009 removes
--
-- WHAT THIS DOES AND DOES NOT PROVE
--
-- It proves that migrations 0009-0029 transform this shape into schema.sql, and
-- it will prove the same for every migration added from now on. That is the
-- point: new work is covered automatically.
--
-- It does NOT independently verify tables that appear in no migration (tags,
-- oauth_sessions, stars, and the rest predate the migration system). Those are
-- copied from schema.sql here, so the test compares them against themselves and
-- can only ever agree. Drift in those tables on a real database is caught by the
-- startup drift check in schema.go, not by this test.
--
-- The 11 dead columns on manifests are typed TEXT because migration 0009 never
-- reads them (its INSERT ... SELECT names only the columns it keeps), so their
-- original types cannot be recovered and do not affect the outcome.
--
-- WHEN YOU ADD A MIGRATION: do not touch this file. It is a fixed starting
-- point. Update schema.sql instead, which is what the migration must converge
-- on. Only edit this file if you are correcting the reconstruction itself.

    version INTEGER PRIMARY KEY,

-- Versions 1-8 are recorded as already applied, because "the state before 0009"
-- means exactly that. Only 0001 still exists as a file; 0002-0008 were deleted
-- from the tree after they shipped, and migration 0009's own comment confirms
-- 0004 was recorded on production.
--
-- This also keeps the test off a live rake: migration 0001 is the example
-- migration, whose query is `SELECT COUNT(*) FROM schema_migrations`. go-libsql
-- rejects a row-returning statement passed to Exec ("Execute returned rows"), so
-- 0001 would fail hard on any database that has not recorded it. Every real
-- database recorded it years ago, so this is invisible in production, but a
-- future migration that opens with a SELECT would fail the same way. Migrations
-- must not return rows.
