+## Authentication and recovery
+
+- Market-data API keys are separate from the Itô compute CLI's device login.
+  Do not run `ito login`, `ecc ito login`, or open a browser for this skill:
+  those credentials are not a documented substitute for a `baskets:read` or
+  `markets:read` API key. Return control to the originating agent after stating
+  the missing scope and operator-driven access requirement.
+- On `AUTH_MISSING`, request a scoped key through the user's established Itô
+  access channel without collecting it in chat. On `AUTH_REJECTED`, say the key
+  may be expired, revoked, or missing the required read scope.
+- On `RATE_LIMITED`, respect `retry_after_seconds`; do not loop automatically.
+  On `TIMEOUT` or `UPSTREAM_ERROR`, preserve prior cited facts, label the live
+  snapshot unavailable, and offer a bounded retry. Never replace failed live
+  data with invented values.
+- `ITO_MARKET_API_URL` may override the API origin for deterministic local
+  tests. In normal use keep the default `https://itomarkets.com/api/v1`.
