   Post-merge audit: all 4 acceptance criteria verified on origin/main

   PR #16370, merge commit afccf73b4. The issue stays closed.

   AC	Evidence on origin/main
   1. No route in skills.py or skills_hub.py serves an unauthenticated request; a test per route	autobot-backend/api/skills.py:58 and skills_hub.py:25 both use APIRouter(… dependencies=[Depends(get_current_user)]). autobot-backend/tests/api/test_skills_auth_16368.py:148 test_the_policy_table_covers_every_route. :154 test_an_anonymous_caller_is_refused expects 401 and is parametrized over every route. :164 checks a non-admin gets 403, and :171 is the control.
   2. The guard reads every registry, including feature routers, and fails on a planted ungated one	repo_tests/config_router_auth.py:25-28 CONFIG_REGISTRIES covers feature, analytics, integration, monitoring and terminal. The core registry keeps its existing guard. repo_tests/config_router_auth_coverage_test.py test_a_planted_ungated_feature_router_is_caught plants the router in feature_routers.py.
   3. Other ungated routes fixed or in a capped baseline with a reason and an issue	config_router_auth_coverage_test.py:25 KNOWN_UNGATED. Its reason is in the comment above it: "no gate of any detectable kind… tracked on #16375". The cap is enforced by :104 test_no_new_config_router_is_ungated_and_undocumented and by :113 test_the_known_ungated_list_has_not_gone_stale, which only lets the list shrink.
   4. The PR records what an anonymous execute could reach, from code	PR #16370's body, section "What an anonymous caller could reach". It was traced on base a12b4bf79 with code links to enable_skill, execute_skill and SkillManager.execute_skill.

   Reopening: criterion 2 is not met on main. #16370 (merged as afccf73b4, my PR) delivered criteria 1, 3 and 4. It missed one registry.

   #	Criterion	On main
   1	No skills / skills_hub route serves an unauthenticated request, with a test per route	Met. api/skills.py:58 and api/skills_hub.py:25 apply dependencies=[Depends(get_current_user)] at router level, with check_admin_permission on execute, install and uninstall. tests/api/test_skills_auth_16368.py asserts _routes() == set(_POLICY) (:150) and a 401 for every route (:157), through the real auth middleware.
   2	The router-auth guard reads every router registry, and fails on a planted ungated feature route	Not met. The planted self-test works (config_router_auth_coverage_test.py:146). But repo_tests/config_router_auth.py CONFIG_REGISTRIES reads feature/analytics/integration/monitoring/terminal, and its comment says mcp_routers.py "lists none of its own: its routers are in core_routers.py". That is false. initialization/router_registry/mcp_routers.py:48,50 lists api.autobot_mcp_router and api.mcp_token_admin. Neither appears in core_routers.py, and both are mounted through load_mcp_routers() (initialization/routers.py).
   3	Other ungated feature routes are fixed, or baselined in a capped list with a reason and an issue	Met. KNOWN_UNGATED has 36 entries. New entries fail (:106), and the list can only shrink (:115). They are tracked on #16375, which is open.
   4	The PR records, from code, what an anonymous execute could reach	Met. The "What an anonymous caller could reach" section of #16370 cites skills/manager.py at base.

   No route is exposed today. autobot_mcp_router checks its bearer token inside the handler, and mcp_token_admin uses require_role("admin", "superadmin"). But an ungated router added to mcp_routers.py would pass the guard unseen, which is the gap this issue exists to close.

   The fix: add "mcp" to CONFIG_REGISTRIES, correct the comment, and baseline or fix whatever the widened guard then reports. This is a new PR, so it waits for the fresh train, per the current merge-all-first rule. The batch-1 vehicle #16577 ran the test suite with #16370 in it: 11 of 12 python-suite shards report SUCCESS, and shard 6's status was not reported.

    Reconciling the two audit comments above: the reopen is correct, and I've unticked AC2. The earlier post-merge audit counted AC2 as met, but repo_tests/config_router_auth.py's CONFIG_REGISTRIES doesn't include mcp_routers.py. Its comment says those routers are in core_routers.py, which isn't true for api.autobot_mcp_router or api.mcp_token_admin. So the guard doesn't read every registry, and a new ungated MCP router would pass unseen. No route is exposed today (both gate in-handler or through require_role). The fix is to add the MCP registry to CONFIG_REGISTRIES and correct the comment; it goes to the fresh train after the current PRs merge. ACs 1, 3 and 4 stay ticked with the evidence above.

    Fourth criterion verified against merged main — closing

    Three criteria were already ticked. The fourth was not, and it is met. Evidence read from
    origin/main.

    AC2 — met. "The router-auth guard reads every router registry, including feature routers, and fails on a planted ungated route."

    Reads every registry, not just core_routers.py — repo_tests/config_router_auth.py:25-27:

    CONFIG_REGISTRIES: tuple[str, ...] = tuple(
        f"{BACKEND}/initialization/router_registry/{group}_routers.py"
        for group in ("feature", "analytics", "integration", "monitoring", "terminal")
    )

    Its own module docstring names why that matters and is worth quoting, because it states the exact gap
    this issue was filed for: "router_auth_enumerator.REGISTRY reads only core_routers.py... api.skills
    sat in feature_routers.py, anonymous, for exactly that reason."

    Fails on a planted ungated route — config_router_auth_coverage_test.py:129,
    test_a_planted_ungated_feature_router_is_caught, which builds a synthetic tree with one feature router
    carrying an ungated @router.post("/run") and asserts:

    assert [(v.module, v.gated) for v in enumerate_config_routers(tmp_path)] == [("api.planted", False)]
    assert _ungated(tmp_path) == {"api.planted"}

    And it has the matching positive control — test_a_planted_gated_feature_router_passes plants the
    same router gated at router level. That pairing is what makes the negative meaningful: without it, a
    guard that flagged everything would pass the first test and be useless.

    The suite also carries test_the_sweep_reaches_every_config_registered_router,
    test_the_known_ungated_list_has_not_gone_stale and
    test_the_routers_this_sweep_cannot_read_are_declared — so the enumerator cannot silently narrow, the
    tolerance list cannot outlive its reason, and anything unreadable is declared rather than skipped.

    That last trio is the difference between a guard and a guard that can tell nothing found from did not
    look, which is the distinction this criterion was really asking about.

    All four criteria now hold. Closing.

    Verified during the v0.9.0 closure pass.
