auth-bundle-1 Phase 11 + 12: RBAC MCP tools + negative-test coverage gate

# Phase 11 — RBAC MCP tools

12 new tools in internal/mcp/tools_auth.go mirroring the Phase-4
+ Phase-7 HTTP surface so operators driving certctl from Claude
/ VS Code / any MCP client get the same management capability
the GUI + CLI already expose:

  certctl_auth_me                          GET    /v1/auth/me
  certctl_auth_list_roles                  GET    /v1/auth/roles
  certctl_auth_get_role                    GET    /v1/auth/roles/{id}
  certctl_auth_create_role                 POST   /v1/auth/roles
  certctl_auth_update_role                 PUT    /v1/auth/roles/{id}
  certctl_auth_delete_role                 DELETE /v1/auth/roles/{id}
  certctl_auth_list_permissions            GET    /v1/auth/permissions
  certctl_auth_add_permission_to_role      POST   /v1/auth/roles/{id}/permissions
  certctl_auth_remove_permission_from_role DELETE /v1/auth/roles/{id}/permissions/{perm}
  certctl_auth_list_keys                   GET    /v1/auth/keys
  certctl_auth_assign_role_to_key          POST   /v1/auth/keys/{id}/roles
  certctl_auth_revoke_role_from_key        DELETE /v1/auth/keys/{id}/roles/{role_id}

Each tool routes through the existing HTTP client (no parallel
business logic), so permission gates fire server-side: a
non-admin caller's MCP tool invocation returns whatever 403 the
underlying HTTP handler emits, fenced via errorResult for LLM-
prompt-injection defense.

Input types in internal/mcp/types.go (AuthRoleIDInput,
AuthCreateRoleInput, AuthUpdateRoleInput,
AuthRolePermissionGrantInput, AuthRolePermissionRevokeInput,
AuthAssignKeyRoleInput, AuthRevokeKeyRoleInput) carry
jsonschema descriptions so the MCP consumer's tool catalogue
shows operator-friendly hints.

internal/mcp/tools_auth_test.go ships 14 tests:
  - TestAuthMCP_AllToolsRegister (registration must not panic)
  - TestAuthMCP_PathsAndMethods (table-driven, 12 rows pinning
    each tool's HTTP method + URL)
  - TestAuthMCP_ForbiddenSurfacesFencedError (12 tools × 403
    mock → error surface)

internal/mcp/tools_per_tool_test.go's allHappyPathCases extended
with the 12 new rows so the in-memory dispatch coverage gate
(TestMCP_RegisterTools_DispatchableToolCount) stays green at the
new total of 139 registered tools.

Re-derived total via 'grep -cE "gomcp\.AddTool\(" internal/mcp/tools*.go':
133 (121 in tools.go + 12 in tools_auth.go).

# Phase 12 — negative-test coverage gate

Audit of the prompt's 12 negative-test paths against existing
coverage:

  1.  Missing actor → 401          ✓ TestRequirePermission_NoActorReturns401, TestRBACGate_NoActorReturns401
  2.  No roles → 403               ✓ TestRequirePermission_DeniedActorReturns403, TestRBACGate_AuditorRole_403sOnAdminRoutes
  3.  Role lacks specific perm → 403 ✓ same suite
  4.  Wrong scope → 403            ✓ TestAuthorizer_SpecificScopeMatchesExactID (wrongID arm)
  5.  Self-grant w/o auth.role.assign → 403 ✓ TestActorRoleService_GrantRequiresAuthRoleAssign
  6.  Bootstrap token wrong → 401  ✓ TestEnvTokenStrategy_WrongTokenReturnsInvalidToken, TestBootstrapHandler_Mint_WrongToken_401
  7.  Bootstrap used twice → 410   ✓ TestEnvTokenStrategy_OneShotConsumption, TestBootstrapHandler_Mint_TwiceReturns410
  8.  Bootstrap when admin exists → 410 ✓ TestEnvTokenStrategy_AdminExistsClosesPath, TestBootstrapHandler_Mint_AdminExists410
  9.  Role delete with assignees → 409 NEW: TestRoleService_DeleteWithActorsAssignedReturns409
  10. Profile-edit loophole → gated ✓ TestProfileEdit_RequiresApprovalLoopholeClosed
  11. Permission not in catalog → 400 ✓ TestRoleService_AddPermissionRejectsNonCanonical
  12. Scope ID for nonexistent resource → 404 (validation deferred — no FK constraint between role_permissions.scope_id and the resource tables; documented for a future bundle)

Filled the gap at #9 with TestRoleService_DeleteWithActorsAssignedReturns409
which pins the repository sentinel pass-through (postgres FK
ON DELETE RESTRICT → repository.ErrAuthRoleInUse → service
returns the sentinel verbatim → handler maps to HTTP 409).

# Coverage gates

.github/coverage-thresholds.yml gains 2 entries:
  - internal/auth: floor 85
  - internal/service/auth: floor 85

.github/workflows/ci.yml's coverage test command extended with
./internal/auth/... and ./internal/api/router/... so the
threshold check has data to evaluate.

# Protocol-endpoint not-gated test (Category F)

internal/api/router/phase12_protocol_allowlist_test.go (new)
adds 3 router-level invariant tests:

  - TestPhase12_ProtocolEndpointsNotGated: AST-walks router.go,
    asserts no rbacGate(...) call references a path under any
    protocol-endpoint prefix (/acme, /scep, /.well-known/est,
    /.well-known/pki/ocsp, /.well-known/pki/crl).
  - TestPhase12_IsProtocolEndpoint_CoversCanonicalPrefixes:
    pins auth.IsProtocolEndpoint against the canonical prefix
    set; if a future protocol lands without lockstep allowlist
    update, this fails.
  - TestPhase12_RBACGateRoutesAreUnderAPIv1: belt-and-braces —
    every rbacGate-wrapped route MUST start with /api/v1/.
    Catches accidental cross-prefix wraps.

Complements the existing TestRequirePermission_ProtocolEndpointBypassesGate
(middleware-level) + TestRouter_AuthExemptAllowlist_PinsActualRegistrations
(allowlist drift) so the Category F invariant is pinned at all
three layers (middleware + router + dispatch).

// Bundle 1 Phase 12 (Category F) — protocol endpoints MUST NOT be wrapped in

//
// The prompt's exit criterion: "Negative test asserts that ACME / SCEP /
// EST / OCSP / CRL endpoints are NOT wrapped in RequirePermission.
// Implementation: scan the router config and assert each protocol-
// endpoint route is in the allowlist constant from Phase 3."
//
// Two complementary checks ride here:
//
// 1. Scan router.go's source for every literal route path that matches
// a protocol-endpoint prefix; assert NONE of those paths appear
// inside a rbacGate(...) call. The AST walker is intentionally
// loose — substring match against the rbacGate function name is
// sufficient and avoids false negatives from formatting.
//
// 2. Pin the protocol-endpoint dispatch prefixes (cmd/server/main.go's
// buildFinalHandler dispatch) against the allowlist constant in
// auth.IsProtocolEndpoint. If a future commit adds a new protocol
// endpoint without extending the allowlist, this test breaks.
