Phase 5 Plan 02: Album/Collection vertical slice Summary

Album/Collection slice with six gormigrate steps, Jsonable/MoneyString casts, lagoon.Validate, ordered album_artists pivot writes, and PHP lifecycle hooks proven on real Postgres

Performance

• Duration: 27 min
• Started: 2026-09-18T16:55:11Z
• Completed: 2026-09-18T17:22:30Z
• Tasks: 3
• Files modified: 32

Accomplishments

• Six Fonoteka migrations widen collections/albums (including track_titles and TEXT discogs_id) and create artists (Various Artists seed), styles, ratings, and reservations; each rolls back in isolation
• lagoon.Jsonable[T] round-trips SQL NULL vs '[]'; MoneyString formats Postgres numeric(10,4) to a 4-decimal string with no binary floating type in the cast
• Artist/Genre/Style BeforeValidate/AfterDelete and Collection BeforeDelete cascade (via WithSoftDeleteCascade) are ported from PHP and tested against real Postgres
• lagoon.Validate translates this slice's rule strings (between, quoted oneof, custom money range, unique:table with deleted_at) and fails loudly on unknown tokens
• SaveAlbum uses the PHP FILL_FIELDS subset, syncArtists delete-then-insert, and Album.BeforeSave (refreshTrackTitles + stampMarketPrice) including the PHP ceiling case "12.55555" → "12.5556"

Plan metadata: pending (this file)

Files Created/Modified

• lagoon/jsonable.go, lagoon/jsonable_test.go — TEXT JSON cast, NULL vs []
• lagoon/validate.go, lagoon/validate_test.go — rule-string engine
• lagoon/fill.go — nil zeros the field; jsonable columns Scan from JSON
• fonoteka.go/plugins/golem15/fonoteka/updates/10_album_slice.go — six migrations
• fonoteka.go/plugins/golem15/fonoteka/models/album.go — final columns, Fillable/Rules, BeforeSave
• fonoteka.go/plugins/golem15/fonoteka/models/{artist,style,album_artist,album_rating,album_reservation,money_string,slug}.go
• fonoteka.go/plugins/golem15/fonoteka/models/{collection,collection_editor,genre}.go — widened + hooks
• fonoteka.go/plugins/golem15/fonoteka/classes/{album_write_service,collection_write_service,artist_resolver,join_tables,serialize}.go
• fonoteka.go/parity/migrate_test.go, album_slice_models_test.go, album_write_service_test.go

Decisions Made

• Jsonable payload is Data (not Value) because driver.Valuer.Value() plus a field named Value fails go vet
• KeepMarketPriceSource is a gorm:"-" flag on Album, set by SaveAlbum when requested contains market_price_source
• CollectionFillFields is name, description — PHP has no CollectionWriteService, so the service list is a subset of Fillable() excluding owner_id
• Various Artists seed uses PHP's natural key name_key = "various artists" (slug various-artists)
• github.com/go-playground/validator/v10 v10.30.4 is added to the framework module as the STACK-named engine behind lagoon.Validate

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] Jsonable cannot use a field named Value

• Found during: Task 2 (Jsonable cast)
• Issue: go vet rejects a struct field and method both named Value; type Jsonable[T] T is also illegal in Go
• Fix: Struct with Data/Valid/NullOnEmpty tagged gorm:"-" so GORM uses Scanner/Valuer instead of walking inner fields
• Files modified: lagoon/jsonable.go, lagoon/jsonable_test.go
• Verification: go vet ./lagoon/... and go test ./lagoon/... -run TestJsonable
• Committed in: 20b0199 (Task 2)

2. [Rule 2 - Missing Critical] Fill ignored nil on non-pointer fields

• Found during: Task 3 (SaveAlbum money nil-in → NULL-out)
• Issue: lagoon.Fill left MoneyString unchanged on explicit nil, so the blank-to-NULL path could not be requested
• Fix: nil now zeros any field; types implementing sql.Scanner (Jsonable) Scan from JSON when convertValue cannot assign
• Files modified: lagoon/fill.go
• Verification: TestSaveAlbumMoneyNormalization nil case
• Committed in: 2c5d92d (Task 3)

3. [Rule 3 - Blocking] Existing migrate tests hardcoded two Fonoteka IDs

• Found during: Task 1 (six new migrations)
• Issue: TestMigrateSeedsCanonicalGenres and TestRollbackLastIsolatesFonoteka expected exactly the Phase-3 pair
• Fix: Expect eight IDs; RollbackLast now asserts create_album_reservations drops only that table
• Files modified: fonoteka.go/parity/migrate_test.go
• Verification: those tests plus TestAlbumSliceMigrationsUpDown
• Committed in: e24a614 (Task 1)

4. [Rule 2 - Missing Critical] widen_albums/collections needed columns omitted from Phase 3 stubs

• Found during: Task 1 (reading folded PHP files)
• Issue: description (collections), public_enabled/public_token_generated_at, and shelf/quantity/notes exist in PHP but not in 00_base.go
• Fix: Added every column the folded PHP files (and the RESEARCH fillable list) require
• Files modified: fonoteka.go/plugins/golem15/fonoteka/updates/10_album_slice.go
• Verification: TestAlbumSliceMigrationsUpDown and later model tests
• Committed in: e24a614 (Task 1)

---

Total deviations: 4 auto-fixed (2 missing critical, 2 blocking) Impact on plan: Required for vet, money nil-out, and a compiling schema that matches PHP. No scope creep. Album.Fillable() has 21 names copied from PHP/RESEARCH (plan said 20 — a count error).

Issues Encountered

None beyond the auto-fixes above.

Authentication Gates

None.

Known Stubs

• classes/artist_resolver.go albumBeforeSaveCallback is a type-guard registration seam; name-to-id find-or-create stays in PHP's ArtistResolver::resolveOne and is not needed for this plan's ID-based syncArtists
• SerializeAlbum/SerializeCollection omit photos/thumbs (Plan 05-04) and reservation context (Phase 12)

User Setup Required

None - no external service configuration required.

Next Phase Readiness

Ready for 05-03 (secrets/encrypted credentials). Wave-2 Album/Collection models, validations, and write-service fill boundaries are in place. lagoon.Validate and lagoon.Jsonable are reusable for later models.

Self-Check: PASSED

• Key files exist on disk (jsonable, validate, 10_album_slice, write services, join_tables, models)
• Commits e24a614, 20b0199, 445133e, 2c5d92d, 4879996 exist
• go vet ./... and go test ./lagoon/... green in summercms.go
• go vet ./... and go test ./... green in fonoteka.go (parity + plugin modules)
