# Phase 5: Data layer full fidelity Verification Report

**Phase Goal:** All 25 Płytarium models and their squashed migration set are ported with matching relations, casts, hooks, and the fillable/hidden/encrypted-cast mass-assignment and serialization discipline. This is security-load-bearing — mass-assignment boundaries and encrypted-at-rest credential casts are named security invariants in the PHP source — apply the security-review agent and the DTO-vs-model convention from the first model onward.
**Verified:** 2026-09-18T19:07:45Z
**Status:** passed
**Re-verification:** No — initial verification

Must-haves are the five ROADMAP success criteria (they override plan-level truths). Plan `must_haves` were checked as supporting evidence. The ROADMAP goal is a data-layer outcome, not a user-story sentence (`gsd-sdk query user-story.validate` → `false`); MVP user-flow coverage is mapped from that outcome below, same pattern as Phase 3.

`05-SECURITY-REVIEW.md` maps T-05-01 through T-05-24; independent greps of `.Reveal()`, `.Association(`, and `AutoMigrate` match the review.

## User Flow Coverage

User story (phase outcome, not a planner-formatted sentence): «A Golem15 developer can persist Płytarium's 25 models on Postgres with PHP-matching schema, fillable/hidden/encrypted discipline, and Winter-shaped attachments, so the Nuxt app's future API layer can sit on a faithful data layer.»

| Step | Expected | Evidence | Status |
|------|----------|----------|--------|
| Port all 25 models + squashed migrations | Tables, columns, indexes match the PHP snapshot; rollback isolates Fonoteka | 26 fonoteka `models.All()` types (25 PHP models + `AlbumArtist` pivot) + Settings dedicated table; `TestSchemaMatchesPHPSnapshot` PASS; `TestRollbackIsolatesFonotekaFullSchema` PASS | ✓ |
| Write Album/Collection/credentials | Unknown and server-owned keys never persist | `lagoon.Fill` + `AlbumFillFields`/`CollectionFillFields` + credential narrower list; `FuzzSaveAlbum`/`FuzzSaveCollection`/credential fuzz seed corpus PASS | ✓ |
| Serialize without leaking secrets | Hidden columns and Encrypted plaintext absent from JSON | `TestHiddenNeverMarshals` (26+2 models); `Encrypted.MarshalJSON`/`String`/`GoString` redact; `.Reveal()` only in tests | ✓ |
| Attach photos/image | Morph PHP class string, ordered photos, lazy Winter-named thumbs, soft-delete keeps blobs | `MorphName()` on Album/Collection; `TestAttachSmoke` PASS | ✓ |
| Outcome | Schema equals PHP (allow-listed diffs only); fill/encryption invariants hold | This session: schema-diff, rollback, money, encrypted, hidden-marshal, attach-smoke, cross-plugin callback all green | ✓ |

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
| --- | ------- | ---------- | -------------- |
| 1 | All 25 models exist with matching table names, columns, indexes and defaults, and every Go migration runs up and down individually; the final schema matches PHP's (migrations are squashed per final-state table). `summer migrate:rollback --plugin=fonoteka` rolls back only that plugin's last migration. | ✓ VERIFIED | RESEARCH inventory rows 1–25 all have a Go model + `init()` `Register`. Extra: `AlbumArtist` pivot and dedicated `golem15_fonoteka_settings` (Open Question 2). Committed `parity/testdata/php_schema_snapshot.sql` is a real `pg_dump` (2245 lines, Postgres 16.15). `TestSchemaMatchesPHPSnapshot` this session PASS — diffs `information_schema` columns/uniques/FKs/`pg_indexes` with three commented `allowedDiffs` (settings table, users column-count, extra oauth_refresh_tokens.user_id FK). `TestRemainingMigrationsUpDown` and `TestRollbackIsolatesFonotekaFullSchema` PASS: last Fonoteka ID `202609180018_create_fonoteka_settings` rolls back alone; user history and earlier Fonoteka tables survive. `lagoon.Migrate(gdb, nil)` creates `system_files` (`TestMigrateRunsSystemFilesFirst` PASS). Defaults/nullability are not in the automated diff (commented P3 D-17 type-family canonicalization); behavioral tests cover the load-bearing ones (settings singleton seed, `reservations_allowed`, unique `public_token`). |
| 2 | A many-to-many relation with pivot business columns (`album_artists.sort_order`, `CollectionEditor.role/granted_at/granted_by`) round-trips correctly for a 3+ artist album; belongsTo/hasOne/hasMany relations return ordered results. | ✓ VERIFIED | `syncArtists` is delete-then-`Create` on `golem15_fonoteka_album_artists` with `SortOrder: i` — zero `.Association(` calls in production (only a forbid comment in `lagoon/relations.go`). `classes/join_tables.go` `init` registers `RegisterJoinTable` for `Album.Artists`/`AlbumArtist` and `Collection.Editors`/`CollectionEditor`; `plugin.go` `Boot` runs `classes.RegisterHooks`. This session: `TestAlbumArtistsOrderRoundTrip` PASS (3 artists, shuffle, pivot `ORDER BY sort_order`); `TestCollectionEditorsPivotRoundTrip` PASS (`role`/`granted_at`/`granted_by` via direct take + `Preload("Editors")`). Ordered attachMany photos: `TestAttachSmoke` `ORDER BY sort_order`. Note: most belongsTo/hasOne/hasMany are FK columns rather than GORM association fields (`Album` has no `Ratings`/`Reservation`/`Collection` field); reads that need order use explicit `ORDER BY`, matching RESEARCH's "not relation-preload magic" for pivots. |
| 3 | The fill boundary of the PHP write services (at minimum Album, Collection and the four credential models) is fuzzed against real Postgres with random extra and server-owned keys, asserting nothing outside the allow-list is persisted (service-level, this phase). Serialization honors the hidden deny-list with an explicit per-call override. | ✓ VERIFIED | Two-layer fill: `Album.Fillable()` includes `collection_id`/`market_price_source`; `AlbumFillFields` excludes them (`TestSaveAlbumFillFieldsSubset`). `SaveAlbum`/`SaveCollection` call `lagoon.Fill` with the narrower list. Credential fuzz uses `credentialWriteFields` stripping `user_id`/`organisation_id`/`api_key`/`token`. This session: `FuzzSaveAlbum`/`FuzzSaveCollection`/`FuzzSaveUserAiCredential` seed corpus PASS against testcontainers Postgres; `FuzzFill` (framework fixture) PASS under `-short`. `json.Unmarshal` into GORM models is absent from production plugin code. Hidden: `json:"-"` + `Hidden()`; `classes.TestHiddenNeverMarshals` walks 26 fonoteka + 2 user models (PASS). Override is greppable `Encrypted.Reveal()` (D-08), not a serializer flag — production call sites: none. HTTP DTO fuzz is Phase 12 per this same criterion. |
| 4 | The money cast round-trips the PHP ceiling and blank-string cases as a fixed 4-decimal JSON string (never `float64`), and an encrypted-at-rest credential column is AES-GCM encrypted at rest and hidden from serialization. | ✓ VERIFIED | `MoneyString` is `string` + `big.Rat.FloatString(4)`; no `float64` in `fonoteka.go` plugin/model code. `Album.BeforeSave` → `stampMarketPrice`. This session: `TestSaveAlbumMoneyNormalization` PASS (`""`/`nil`/`"not-a-price"` → SQL NULL/`""`; `"12.55555"` → `"12.5556"`; JSON is a quoted string or `null`). `lagoon.Encrypted`: stdlib `crypto/hkdf` + AES-256-GCM, version prefix `0x10`, `Reveal` only accessor, `MarshalJSON`/`String`/`GoString` emit `[redacted]`. `TestEncryptedRoundTrip`, `TestEncryptedFreshNonce`, `TestEncryptedRedacts`, `TestEncryptedPreviousKeysFallback`, `TestEncryptedLoadAppKeyRejectsInvalid` PASS. Credential models type `api_key`/`token` as `lagoon.Encrypted` `json:"-"` + `Hidden()`. `OpenFromApp` (serve + migrate CLI) calls `loadEncryptionKeysFromApp`; empty `app.key` fails with `SUMMER_APP__KEY`. `DecryptLaravelPayload` is only referenced from `laravel_decrypt.go` and its test. |
| 5 | Paginated responses use the exact `{data, meta{current_page,last_page,per_page,total}}` envelope with no `links` key; another plugin extends a model's lifecycle through the GORM callback registry and a companion migration without editing the owning plugin's file; soft-deletable + uniquely-keyed tables pass a delete-then-recreate test. | ✓ VERIFIED | `lagoon.Page`/`PageMeta` JSON tags are exactly those four meta keys; `TestPaginateEnvelope` PASS (marshaled JSON has `data`/`meta`, no `links`; nil rows → `[]`). No production handler calls `Paginate` yet — this phase has no paginated HTTP routes (Phase 12). DATA-11: `parity/fixtureplugin` is constructed in-process, not `party.Register`ed, not imported from `app/app.go`. `Boot` registers `fixtureplugin:demo_album_created` after `gorm:create` gated on `models.Album`; own gormigrate adds `demo_extension_note`. `TestCrossPluginCallback` PASS (column exists, Album create increments counter, Genre does not, companion struct round-trips the note). `TestCollectionPublicTokenDeleteThenRecreate` PASS: soft-delete then reuse `public_token` → unique violation (plain UNIQUE, no partial index); hard-delete frees it. |

**Score:** 5/5 truths verified

Supporting plan truths that hold in code (not extra score rows): models-leaf probe closed (todo `done/`); Winter-directory plugins with `Models()`/`Migrations()` → `All()`; `lagoon.Fill` dropped-key logging; `WithSoftDeleteCascade` Collection→Album (`TestCollectionBeforeDeleteCascadesAlbums`, `TestWithSoftDeleteCascadeRollback`); `lagoon.Validate` unique respects `deleted_at`; `system_files` before plugin sets; Winter `ThumbFilename`/`PartitionDirectory`; blob via `gocloud.dev/blob` (memblob in tests, fileblob URL in `config/storage.yaml`); `key:generate`; organisations in the user plugin with no `widen_users`; notifications/wishlist tables have no `REFERENCES` on `user_id`/`collection_id`; security review maps every T-05-*.

### Required Artifacts

`gsd-sdk query verify.artifacts` reports missing files because PLAN paths are `summercms.go/lagoon/...` and `fonoteka.go/...` — those are not subdirectories of cwd. Verified against the two-repo layout (`lagoon/X` in cwd, `/media/nvme/dev/golem15/summercms.io/summercms/fonoteka.go/X` in the sibling).

### Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
| ----------- | ---------- | ----------- | ------ | -------- |
| DATA-03 | 05-01, 05-02 | timestamps, soft delete, lifecycle hooks, in-tx cascade | ✓ SATISFIED | GORM-native BeforeSave/BeforeDelete/AfterDelete; Collection cascade; BeforeValidate is a method tests call (not auto-dispatched — lifecycle.go documents this) |
| DATA-04 | 05-02 | belongsTo/hasOne/hasMany/belongsToMany + pivot business columns | ✓ SATISFIED | album_artists.sort_order + CollectionEditor columns round-trip; FKs for other relations |
| DATA-05 | 05-02 | rule strings → Laravel-shaped 422 map | ✓ SATISFIED | `lagoon.Validate`; `SaveAlbum` returns `FieldErrors`; unique respects soft-delete |
| DATA-06 | 05-01, 05-02, 05-06 | mass assignment via fillable; hidden + override | ✓ SATISFIED | service-level Fill this phase; HTTP request DTOs deferred to Phase 12 by SC 3 |

No orphaned Phase 5 IDs in REQUIREMENTS.md. HTTP half of DATA-06 is explicitly Phase 12.

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
| ---- | ---- | ------- | -------- | ------ |
| `lagoon/lifecycle.go` | 9–12 | `HasBeforeValidate` is not registered as a GORM callback | ℹ️ Info | Artist/Genre/Style slug defaulting is caller-invoked; GORM-native hooks (BeforeSave/Delete) do fire. Discretion in CONTEXT.md. |
| `classes/artist_resolver.go` | 34–43 | GORM callback body is a comment | ℹ️ Info | Intentional models-leaf seam; `SaveAlbum` calls `ResolveArtists` + `syncArtists` |
| `surf/serve.go` / `app/app.go` | — | `attach.OpenBucket` / `attach.Publish` never called at boot | ℹ️ Info | No HTTP upload/static route this phase (T-05-16). Helpers + tests exist. |
| `lagoon/paginate.go` | — | `Paginate` used only from its test | ℹ️ Info | No paginated HTTP handler this phase |
| `models/album.go` | — | No GORM fields for hasMany ratings / hasOne reservation / belongsTo collection | ℹ️ Info | FKs exist; Preload convenience deferred. Named SC 2 pivots are implemented. |
| `internal/build/artifact.go` | 177 | `TODO: describe` in make:* stub text | ℹ️ Info | Phase 4 scaffolding template, not Phase 5 debt |
| — | — | No `TBD`/`FIXME`/`XXX` in Phase 5 Go code | — | Debt-marker gate clean |

Independent security greps (excluding `.planning/`): `.Reveal()` only in `encrypted.go` definition + tests; `.Association(` only the forbid comment; production `AutoMigrate` zero (`TestNoAutoMigrate`, `TestPluginMigrationsDoNotUseAutoMigrate`).

### Human Verification Required

None. Schema equality, fill/encryption, thumbs, rollback isolation, and the fixture plugin are covered by testcontainers tests run this session.

### Gaps Summary

No blocking gaps. Phase goal is achieved in the codebase: 25 Płytarium models plus the Settings dedicated table and AlbumArtist pivot, squashed migrations whose final schema diffs equal the committed PHP snapshot (three documented allow-list entries), two-layer fillable fuzzed at service level, Encrypted AES-GCM with redaction, Winter-shaped attachments, pagination envelope, DATA-11 fixture plugin, and isolated `migrate:rollback --plugin`.

Non-blocking follow-ups already scheduled: HTTP DTO fuzz (Phase 12), StaticHandler `is_public` gate and bucket publish at serve (Phase 6), `widen_users` (Phase 7 AUTH-02).
