+# Bead bf-67io: SQL Migration File Verification
+
+## Task
+Infra: SQL migration file (migrations/0001_initial.sql) — schema is embedded in db.go but no standalone migration file exists per §11.1 plan inventory
+
+## Status
+**ALREADY COMPLETE** - Work was done in commit 31678be prior to bead assignment
+
+## Verification
+- Migration file exists at: `migrations/0001_initial.sql`
+- Created in commit: `31678be` (2026-05-22 15:52:54)
+- Contains all 20 tables from `cmd/acb-api/db.go`:
+  - bots, matches, match_participants, jobs, rating_history
+  - seasons, season_snapshots, series, series_games
+  - predictions, predictor_stats
+  - maps, map_scores, map_votes, map_fairness
+  - programs, playlists, playlist_matches
+  - replay_feedback, feedback_upvotes
+  - enrichment_requests
+
+## Schema Completeness
+All columns from `db.go` are present in the migration file, including:
+- `matches.combat_turns` (line 41)
+- `matches.enrichment_requested_at` (line 43)
+- `bots.debug_public` (line 30)
+- `series.bracket_round`, `bracket_position`, `featured` (lines 116-118)
+
+## Notes
+The migration file uses clean `CREATE TABLE` statements (not `CREATE TABLE IF NOT EXISTS`), which is the correct approach for an initial migration. The idempotent migrations in `db.go` are appropriate for runtime schema enforcement.
