Add 148 integration tests exercising actual SQL against PostgreSQL for
all previously untested repository files. Includes 6 new fixture helpers
in testhelpers_db.go and CI PostgreSQL service configuration.
Discovered and documented existing RecordPurchase SQL bug (ambiguous
column reference in ON CONFLICT clause).
Replace 4 independent schema management code paths (Docker shell
script, setup wizard pg_restore, test helpers, manual psql) with a
single migration runner embedded in the server binary.
The new server/migrations/ package uses Go embed to bundle all SQL
schemas. On startup, Migrate() creates a schema_version tracking
table, detects existing databases (auto-marks baseline as applied),
and runs pending migrations in transactions.
Key changes:
- Consolidated init.sql + 9.2-update + 33 patches into 0001_init.sql
- Setup wizard simplified to single "Apply schema" checkbox
- Test helpers use migrations.Migrate() instead of pg_restore
- Docker no longer needs schema volume mounts or init script
- Seed data (shops, events, gacha) embedded and applied via API
- Future migrations just add 0002_*.sql files — no manual steps
Codecov requires an account and token to function. Replace it with
a self-contained `go tool cover` step that fails the build if total
coverage drops below 50% (currently ~58%). This catches test
regressions without external service dependencies.
The guild daily RP rollover TODO in handlers_guild_ops.go was stale —
the feature was already implemented via lazy rollover in
handlers_guild.go. Several other items in technical-debt.md were also
resolved in prior commits (typos, db guard investigation). Updated
the doc to reflect current state and bumped codecov-action to v5.
- Add lint to build job's needs so lint failures prevent artifacts
- Combine race detector + coverage into a single test run
- Pin golangci-lint to v2.1.6 to avoid surprise breakage
- Rename workflow from go-improved.yml to go.yml
