<objective>
Close the HTTP-04 verification gap by correcting the live personal-token genres middleware onion and proving the unauthenticated deny path consumes the 60/minute bucket.

Purpose: remove the rate-limit bypass that currently allows unlimited missing/invalid personal-token requests to reach InvScope's 401 path without incrementing the limiter.
Output: the exact `inv_token` -> `throttle:fonoteka-api-token` -> `inv.scope:read` declaration and an isolated assembled-router regression proving request 61 is denied with the PHP-compatible 429 body.

<interfaces>
From `summercms.go/surf/router.go`:
- `Router.wrap` iterates `rt.middleware` from the last name to the first, so the first listed middleware becomes the outermost runtime wrapper.
- `Assemble(app, plugins) (http.Handler, error)` calls `BuildRouter`, which creates a new `FixedWindowLimiter` and `MemoryStore` for that assembled handler.

From `summercms.go/bouncer/registry.go`:
- A guard error without `UnauthorizedWriter` continues the chain without `bouncer.User` or `bouncer.Credential`, allowing `InvScope` to own the exact 401 body per D-08.

From `fonoteka.go/plugins/golem15/fonoteka/plugin.go`:
- `fonoteka-api-token` uses `tok:<id>` when `bouncer.Credential` contains `*models.ApiToken`; otherwise it falls back to `surf.ClientIP` and enforces Max 60 over one minute.

  <action>
    In `Plugin.Routes`, change only the live personal-token genres group's `surf.Use` arguments from `inv_token`, `inv.scope:read`, `throttle:fonoteka-api-token` to `inv_token`, `throttle:fonoteka-api-token`, `inv.scope:read`. This exact source order is required because `surf.Router.wrap` composes last-to-first: `inv_token` remains outermost and resolves a valid credential before the bucket key is computed (preserving `tok:<id>` per D-01/D-06), the throttle then consumes both authenticated and unauthenticated traffic (D-02), and `InvScope` remains the innermost scope/401/403 gate (D-08). Do not move throttle before `inv_token`, do not alter bucket limits or key logic, and do not address unrelated REVIEW.md warnings.

    In `routes_isolation_test.go`, add `TestPersonalTokenGenresUnauthenticatedRequestsAreRateLimited` using the existing real-plugin activation pattern: create a fresh `bootConfig` and `backpack.App`, publish a fresh `bouncer.Registry`, activate exactly `golem15.user` and `golem15.fonoteka`, and register a test-local `inv_token` guard that always returns unauthenticated without implementing `UnauthorizedWriter`. Assemble once with `surf.Assemble`; this construction must be local to the test and not shared or parallelized, so `BuildRouter` supplies a fresh `FixedWindowLimiter`/`MemoryStore` and no other test can consume its bucket.

    Send 61 independent `httptest.NewRequest` calls to `GET /api/v1/fonoteka/genres` through that assembled handler, with no Authorization header and the same explicit `RemoteAddr` on every request. Use a fresh recorder for every call. Assert requests 1 through 60 return 401 and, after `strings.TrimSpace`, the existing `{"error":"Invalid token"}` body, proving the throttle does not replace the normal deny response before exhaustion. Assert request 61 returns 429 and its raw body is exactly `{"message":"Too Many Attempts."}`, with `X-RateLimit-Limit: 60` and `X-RateLimit-Remaining: 0`. The test must exercise the production route, real middleware factory, real named bucket, and real limiter; do not hand-compose middleware or call `FixedWindowLimiter` directly.

    Search production route declarations under `fonoteka.go/plugins/golem15/fonoteka` for any other route containing both `inv.scope:` and `throttle:`. Apply this same order only if another live production route exists in the current tree; do not change test-only boot probes, empty future groups, or unrelated route stacks speculatively.

    - `routes.go` contains `surf.Use("inv_token", "throttle:fonoteka-api-token", "inv.scope:read")` on the live `/api/v1/fonoteka/genres` group and does not contain the old `inv_token`, `inv.scope:read`, `throttle:fonoteka-api-token` order.
    - `TestPersonalTokenGenresUnauthenticatedRequestsAreRateLimited` calls the handler returned by `surf.Assemble` for the real two-plugin set; it does not construct a limiter or middleware chain directly.
    - The test uses one fresh assembled handler and a stable explicit RemoteAddr for all 61 requests, with no `t.Parallel`, global handler, or shared limiter state.
    - Requests 1-60 assert HTTP 401 plus trimmed body `{"error":"Invalid token"}`; request 61 asserts HTTP 429 plus raw body exactly `{"message":"Too Many Attempts."}`, `X-RateLimit-Limit: 60`, and `X-RateLimit-Remaining: 0`.
    - The targeted command exits 0 under `-short`, proving the regression does not require Docker, Postgres, or shared test state.

## Trust Boundaries

| Boundary | Description |
|----------|-------------|
| unauthenticated client -> personal-token route | Missing or invalid bearer traffic is attacker-controlled and must consume a bounded per-IP budget before credential/scope denial returns |
| inv_token context -> limiter key resolver | Valid credentials must be available before rate limiting so users receive independent tok:<id> budgets; unauthenticated traffic must safely fall back to ClientIP |

## STRIDE Threat Register

| Threat ID | Category | Component | Disposition | Mitigation Plan |
|-----------|----------|-----------|-------------|-----------------|
| T-06-21 | Denial of Service | `/api/v1/fonoteka/genres` middleware chain | mitigate | Put `throttle:fonoteka-api-token` between `inv_token` and `inv.scope:read`; the assembled-route 61-request regression proves missing credentials cannot bypass the 60/minute deny-path budget |
| T-06-22 | Denial of Service | `fonoteka-api-token` key selection | mitigate | Keep `inv_token` outermost so valid credentials populate `bouncer.Credential` before the bucket key closure runs and retain per-token `tok:<id>` isolation rather than sharing an IP bucket |
| T-06-SC | Tampering | package supply chain | accept | This gap closure performs no npm, pip, cargo, or Go module install and changes no dependency manifest; it uses only already-audited Phase 6 code |

From `fonoteka.go`, run `go test ./plugins/golem15/fonoteka -run 'TestPersonalTokenGenresUnauthenticatedRequestsAreRateLimited|TestFullRouteTableAuthGroupMutualExclusivity' -count=1 -short`, then `go test ./plugins/golem15/fonoteka/... -count=1 -short`. Confirm a source grep shows only the target live order for the personal-token genres route.

<success_criteria>
- The live personal-token genres group declares `inv_token`, `throttle:fonoteka-api-token`, `inv.scope:read` in that exact order.
- A fresh assembled-router test proves requests 1-60 without credentials return the existing 401 body and request 61 from the same IP returns the exact PHP-compatible 429 body and exhausted-limit headers.
- The regression runs under `-short` with no database or external service and cannot inherit limiter counters from another test.
- HTTP-04's verification blocker and REVIEW CR-01 are directly closed without changing unrelated warnings or deferred work.
