Phase 5 Plan 01: Winter layout and lagoon primitives Summary

Models-leaf rule confirmed on three more plugins; fonoteka.go restructured into Winter directories with self-registering registries; lagoon.Fill, lifecycle cascade, Paginate, and RegisterJoinTable shipped with tests

Performance

• Duration: 16 min
• Started: 2026-09-18T16:32:17Z
• Completed: 2026-09-18T16:48:36Z
• Tasks: 4
• Files modified: 37

Accomplishments

• Probed keios.eu golem15/user, jz golem15/chat, and pxpx pixelpixel/checkout; every live models/ → sibling edge is a cast or service-calling hook, so the leaf rule holds and the folded todo is closed
• Restructured both Phase-3 fonoteka.go plugins into models/, classes/, updates/ (plus controllers/ and middleware/ on fonoteka) with Register/All collectors; plugin.go returns models.All()/updates.All() and never needs a later-plan edit
• lagoon.Fill copies only allow-listed keys, logs dropped keys once in non-production, and stays silent in production; five Has* hook interfaces plus WithSoftDeleteCascade are integration-tested on testcontainers Postgres
• lagoon.Paginate emits {data, meta{current_page,last_page,per_page,total}} with no links; RegisterJoinTable documents the pivot-write contract and refuses a nil db
• ROADMAP.md and REQUIREMENTS.md no longer treat "27 migrations" as a target; criterion 3's HTTP DTO fuzz is Phase 12's job

Plan metadata: pending (this file)

Files Created/Modified

• .planning/notes/plugin-layout-winter-directories.md — three dated Evidence sections plus widened cast/hook conversion treatments
• .planning/todos/done/verify-models-leaf-rule.md — closed folded todo
• fonoteka.go/plugins/golem15/fonoteka/{models,classes,controllers,middleware,updates}/* — Winter layout and registries
• fonoteka.go/plugins/golem15/fonoteka/plugin.go, routes.go — models.All()/updates.All(), hook Boot, genres route
• fonoteka.go/plugins/golem15/user/{models,classes,updates}/* and plugin.go — same layout for the user plugin
• fonoteka.go/parity/*_test.go — import paths follow the new packages
• lagoon/fill.go, lagoon/fill_test.go — allow-list Fill + HasFillable/HasHidden
• lagoon/lifecycle.go, lagoon/lifecycle_test.go — Has* hooks and transactional cascade
• lagoon/paginate.go, lagoon/paginate_test.go — DATA-10 envelope
• lagoon/relations.go, lagoon/relations_test.go — SetupJoinTable wrapper and pivot-write contract
• .planning/ROADMAP.md, .planning/REQUIREMENTS.md — D-01/D-07 wording

Decisions Made

• The models-leaf rule is confirmed, not excepted: PHP contracts, value objects, formatters, job dispatch, and broadcasting traits convert as casts (move into models/) or service-calling hooks (register from classes/)
• Later Phase 5 plans add files under models/, updates/, and classes/; they do not edit plugin.go
• WithSoftDeleteCascade is a named one-line wrapper around the GORM BeforeDelete transaction, not a second transaction
• Paginate does not slice rows; callers pass an already-sliced DTO list and the helper only computes LastPage
• HTTP-level fill fuzz is explicitly Phase 12; this plan's DATA-06 delivery is the lagoon.Fill primitive

Deviations from Plan

Auto-fixed Issues

1. [Rule 2 - Missing Critical] Nil pagination data marshals as []

• Found during: Task 4 (Paginate envelope)
• Issue: json.Marshal of a nil slice is null, which is Pitfall 4 and would break house REST [] parity
• Fix: Paginate replaces a nil rows argument with []T{}
• Files modified: lagoon/paginate.go, lagoon/paginate_test.go
• Verification: TestPaginateNilDataIsEmptyArray
• Committed in: 52638fb (Task 4 code)

2. [Rule 3 - Blocking] Shipped migration Go identifiers needed package qualifiers after the move

• Found during: Task 2 (plugin restructure)
• Issue: updates/00_base.go cannot stay package fonoteka and still live in the updates subpackage; CanonicalGenres/Genre{} live in models/
• Fix: SQL strings unchanged (P3 D-17); package clause and models.CanonicalGenres/models.Genre{} qualifiers only
• Files modified: fonoteka.go/plugins/golem15/fonoteka/updates/00_base.go
• Verification: go test ./... -run TestParityCorpus passing 1/ported 1; seed rollback still uses the same table/slug SQL
• Committed in: 3171a49 (Task 2)

---

Total deviations: 2 auto-fixed (1 missing critical, 1 blocking) Impact on plan: Both required for []-not-null parity and a compiling Winter-layout move. No scope creep.

Issues Encountered

None.

Authentication Gates

None.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

Ready for 05-02 (Album/Collection slice). Wave-2 plans can add model, update, and class files without editing plugin.go. lagoon.Fill, lifecycle hooks, Paginate, and RegisterJoinTable are available for those models.

Self-Check: PASSED

• Key files exist on disk (lagoon primitives, plugin registries, closed todo, three Evidence sections)
• Commits a9c77fc, 3171a49, fec23e2, 969a5f5, 52638fb, c85fa24 exist
• go vet ./... and go test ./... -short green in summercms.go
• go vet ./... and go test ./... -run TestParityCorpus green in fonoteka.go
• grep "27 migrations" .planning/ROADMAP.md .planning/REQUIREMENTS.md has no matches
