Phase 5 Plan 06: Full-fidelity unit/fuzz coverage and security review Summary

lagoon.Fill and six D-07 write paths fuzzed against real Postgres; every registered model hidden-marshaled; Collection.public_token matches PHP's plain UNIQUE; attach photos/image/thumb/delete smoked; T-05-01..24 mapped in 05-SECURITY-REVIEW.md

Performance

• Duration: 23 min
• Started: 2026-09-18T18:30:26Z
• Completed: 2026-09-18T18:53:12Z
• Tasks: 3
• Files modified: 12

Accomplishments

• FuzzFill ran 20s with zero crashers; non-allow-listed fixture fields never change. FuzzSaveAlbum / FuzzSaveCollection (20s each) and four credential fuzz targets persist against testcontainers Postgres and reject server-owned keys
• TestHiddenNeverMarshals enumerates 26 Fonoteka + 2 user models (28 total) and asserts every Hidden() sentinel and json:"-" field is absent from JSON
• TestCollectionPublicTokenDeleteThenRecreate gets a real unique-violation after soft-delete and succeeds after hard-delete
• TestAttachSmoke covers ordered photos, attachOne image, Winter thumb filename, soft-delete keep, and two-phase force-delete against memblob
• 05-SECURITY-REVIEW.md maps T-05-01 through T-05-24; .Reveal() exists only on the method and in tests; no production AutoMigrate; no Association Mode pivot writes

Plan metadata: pending (this file)

Files Created/Modified

• lagoon/fill_fuzz_test.go — FuzzFill plus nil/empty map smoke
• lagoon/hidden_marshal_test.go — framework HasHidden fixture
• .planning/phases/05-data-layer-full-fidelity/05-SECURITY-REVIEW.md — threat map and greps
• fonoteka.go/plugins/golem15/fonoteka/classes/postgres_test.go — testcontainers harness (parity helpers are package main)
• classes/album_write_service_fuzz_test.go, collection_write_service_fuzz_test.go, credential_write_service_fuzz_test.go
• classes/hidden_marshal_test.go, collection_public_token_test.go, attach_smoke_test.go
• plugins/golem15/fonoteka/go.mod, go.sum — testcontainers-go v0.44.0, gocloud.dev (test imports)

Decisions Made

• The All() hidden-marshal walk lives in fonoteka.go classes tests; putting it in lagoon would import the app into the framework module (CLAUDE.md two-repo rule). The plan's own fallback is used. lagoon.TestHiddenNeverMarshals still exists so the verify command passes
• Credential models have no write-service file; the fuzz path uses Fillable() minus user_id/organisation_id/api_key/token so a fuzzed owner-FK override cannot stick (D-05 two-layer, matching AlbumFillFields excluding collection_id)
• classes.TestMain starts ICU pl-PL Postgres and migrates both plugin sets; activateAppPlugins/parityDB cannot be imported from package main

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] classes tests cannot import parity helpers

• Found during: Task 1
• Issue: activateAppPlugins/parityDB live in fonoteka.go/parity package main
• Fix: classes/postgres_test.go TestMain + lagoon.Migrate of both plugin sets
• Files modified: fonoteka.go/plugins/golem15/fonoteka/classes/postgres_test.go
• Verification: fuzz seeds and 20s runs
• Committed in: 836da04 (Task 1)

2. [Rule 2 - Missing Critical] credential Fillable() includes owner FKs

• Found during: Task 1
• Issue: Using Fillable() as the allow-list would let a fuzzed user_id/organisation_id change the owner, contradicting the acceptance criterion
• Fix: Working allow-list drops owner FKs and Encrypted columns; secrets are set via NewEncrypted then Save
• Files modified: credential_write_service_fuzz_test.go
• Verification: four credential fuzz seed corpora
• Committed in: 836da04 (Task 1)

3. [Rule 3 - Blocking] Hidden-marshal All() cannot live in lagoon

• Found during: Task 2
• Issue: Importing both plugin models.All() from summercms.go would make the framework know about Płytarium
• Fix: Fixture test in lagoon/hidden_marshal_test.go; registry walk in classes/hidden_marshal_test.go (plan-allowed fallback)
• Files modified: both hidden_marshal_test.go files
• Verification: go test ./lagoon/... -run TestHiddenNeverMarshals and go test ./classes/ -run TestHiddenNeverMarshals
• Committed in: 1fcf5ab, 1ecd660 (Task 2)

Total deviations: 3 auto-fixed (1 missing critical, 2 blocking) Impact on plan: Required for compiling tests, the owner-FK assertion, and the two-repo rule. No production-code scope creep.

Issues Encountered

Album.BeforeSave.stampMarketPrice clears market_price_source when stored money is blank. The album fuzz seeds a real price and strips market_price_stored from the fuzzed map so the assertion measures mass-assignment, not money-normalization (already covered by TestSaveAlbumMoneyNormalization).

Production code already existed; TDD tasks wrote tests that pass against it. A leak of collection_id/market_price_source would still fail the fuzz.

Authentication Gates

None.

TDD Gate Compliance

Plan type is execute, not type: tdd. Tasks 1–2 have tdd="true" but cover existing code from 05-01..05-05. No RED commit: a passing test here means the fillable/hidden invariants hold, not that the test is wrong. GREEN is the test commit itself.

Known Stubs

None that prevent this plan's goal.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

Phase 5 is complete. Fill, hidden, encrypted, attach, and schema-diff invariants have closing tests and a committed security review. Ready for Phase 6 (HTTP routing, auth groups, rate limiting). HTTP DTO fuzz remains Phase 12 (D-07). StaticHandler is_public gate remains Phase 6/12 (T-05-16).

Self-Check: PASSED

• Key files exist on disk (lagoon/fill_fuzz_test.go, lagoon/hidden_marshal_test.go, 05-SECURITY-REVIEW.md, classes fuzz/hidden/public_token/attach/postgres tests)
• Commits 7ead5e0, 1fcf5ab, e0a11c3 (summercms.go) and 836da04, 1ecd660, 4f88c2f (fonoteka.go) exist
• go vet ./... and go test ./... green in summercms.go
• go vet ./... and go test ./... plus plugin modules green in fonoteka.go
• FuzzFill / FuzzSaveAlbum / FuzzSaveCollection each ran -fuzztime=20s with zero crashers
• grep AutoMigrate on fonoteka.go/plugins and summercms.go/lagoon production code is zero (test-only mentions)
