Encode the feature-folder layering contract as a CI gate: lib is the floor, store/ui must not import features/app, cross-feature only via the barrel, no cycles. dependency-cruiser resolves the @/ alias via tsconfig; tests excluded. Land as a ratchet: the 738 current violations are seeded into .dependency-cruiser-known-violations.json and ignored via --ignore-known, so HEAD is green and any NEW violation fails CI. Regenerate the baseline as the drain removes an exception; the count is the tracked residual debt. Wired via `npm run dep:check` into a new dependency-cruiser job in eslint.yml and the ci-ok required-check aggregate.

// Architecture / layering guard for the feature-folder structure (PR #1225, group A1).

|
// Encodes the layering contract the restructure established:
|
|
//
|
|
// lib (feature-free infra: api clients, format, i18n, util, media, server, navigation)
|
|
// ▲
|
|
// store / ui (cross-cutting global stores; domain-agnostic primitives) — may import lib
|
|
// ▲
|
|
// cover / music-network (top-level domains — peers; may import lib, store, ui)
|
|
// ▲
|
|
// features/<x> (may import lib, store, ui, cover, music-network, other features via barrel only)
|
|
// ▲
|
|
// app (shell + bridges — may import anything)
|
|
//
|
|
// A lower layer may NOT import a higher one. Cross-feature access goes through the
|
|
// `@/features/<x>` barrel only, never a deep path. No import cycles anywhere.
|
|
//
|
|
// Ratchet: current known violations (residual legacy dirs + documented inversions) are
|
|
// captured in `.dependency-cruiser-known-violations.json` and ignored via `--ignore-known`
|
|
// (see `npm run dep:check`). Any NEW violation fails CI. As the drain (group E) removes an
|
|
// exception, regenerate the baseline so the count ratchets toward zero.
