channel_stream called validate_channel_access, which HTTP-loopbacked to
GET /api/permissions/check — a route that does not exist. Every call 404'd
-> False -> the channel stream closed with WS_1008_POLICY_VIOLATION for
EVERY client, so the real-time channel stream was dead. Removed the
function, its call site, and the now-unused httpx + settings imports.
Post-F004 the panel-token gate is the channel-stream authorization (the
CEO panel is the sole WS client and may view every channel), so the
broken loopback is removed rather than replaced with an in-process check
the CEO always passes. The legitimate enforcement.validate_channel_access
(slugs, in-process static ACL) is a different function and is untouched.
F027 is resolved-by-F004 (no code change): all three per-agent streams
gate on _require_panel_token first, so only the authorized CEO panel can
connect — 'any viewer subscribes to any target' is closed.
TDD; ruff/mypy clean; 530 unit/api+enforcement+RBAC tests green.
F003/F014: /api/v1/do/* only required X-Agent-ID (UUID) — no token check,
unlike the flow routers' role guards. A forged X-Agent-ID passed. Added
require_any_authenticated_agent (token-only; do router serves all roles)
and applied it as a router-level dependency. Binds X-Agent-ID to a verified
HMAC token when ROBOCO_AGENT_AUTH_REQUIRED=true; rejects a forged token
even in dev mode.
F004: /ws/* per-agent streams (channels/agents/sessions/notifications)
never read the nginx-injected X-Agent-Token, so in strict mode an agent on
the Docker network could subscribe to another agent's notifications with
no auth. Added _require_panel_token verifying the CEO panel token against
the CEO identity; wired into all four per-agent streams (system stream
stays operator-only per its docstring). Same strict/dev contract.
TDD: RED tests watched fail (no gate -> 200/accept), then GREEN. ruff+mypy
clean; 399 api/mcp + 29 WS tests green, no regressions.
