 - [x] **HTTP-01**: Plugins register route groups on net/http ServeMux with typed params and regex constraints; unknown and malformed ids both return 404 on ownership-scoped resources
 - [x] **HTTP-02**: Plugins register named middleware that other plugins reference by name; the pipeline order is recover, CORS, locale, auth group, must-change-password, org context, rate limit, handler
 - [x] **HTTP-03**: Three mutually exclusive auth groups share the same handlers with different route subsets: JWT under /_fonoteka/api/v1, personal scoped token under /api/v1/fonoteka, and public groups (onboarding, public/{token}, public-wishlist/{token}, invitation inspection)

 - [x] **HTTP-05**: An auth guard registry lets plugins add guards (JWT, personal token, OAuth bearer) that all resolve to the same current-user accessor
 - [ ] **HTTP-06**: Response conventions are preserved: empty arrays serialize as [], timestamps as +00:00, tri-state booleans keep null, conditional keys are omitted not nulled, and no blanket envelope or error middleware wraps OAuth routes
 - [ ] **HTTP-07**: A guarded outbound fetch helper enforces host allow-lists, byte caps and timeouts for user-supplied URLs (manual cover URL, Discogs cover)

 - [Phase 06]: PublicOnlyMode any-host-when-public is proven via skipReservedCheck httptest, not a live public IP dial — Unit tests must not require outbound network
 - [Phase 06]: Keep inv_token outermost so valid credentials populate bouncer.Credential before the limiter selects tok:<id>. — The named bucket must retain per-token isolation for valid credentials instead of collapsing them onto the IP fallback.
 - [Phase 06]: Place throttle:fonoteka-api-token before inv.scope:read in the personal-token middleware declaration. — Missing and invalid credentials must consume the 60/minute per-IP deny-path budget before InvScope returns its PHP-compatible 401 response.
+- [Phase 06]: Replace the split limiter store protocol with one atomic Attempt operation. — Expiry, threshold comparison, admitted increment, and retry duration must share one mutex critical section so concurrent callers cannot bypass Max.
+- [Phase 06]: Use one inline:domainless namespace plus trusted-proxy ClientIP for every anonymous inline throttle. — Host and inline throttle text must not let anonymous callers rotate rate-limit buckets; authenticated requests retain u:<principal id> isolation.
