+may load-balance across gateway instances) rather than ride one gateway's

+"""Gateway-side relay authentication primitives. EXPERIMENTAL.
+
+The connector⇄gateway channel is authenticated because a gateway may be
+customer-managed and internet-exposed (see the connector repo
+``docs/connector-gateway-auth-design.md``). This module is the **gateway half**
+of two HMAC schemes whose wire bytes must match the connector's TypeScript
+exactly:
+
+1. **WS upgrade auth** (gateway → connector): the gateway presents
+   ``Authorization: Bearer <token>`` on the ``/relay`` WebSocket upgrade, where
+   ``token = make_upgrade_token(gateway_id, secret)``. Mirrors the connector's
+   ``relayAuthToken.ts`` ``makeToken`` (``src/core/relayAuthToken.ts``):
+   ``base64url(f"{payload}:{exp}:{sig}")`` with
+   ``sig = HMAC_SHA256(f"{payload}:{exp}", secret).hexdigest()`` and
+   ``payload == gateway_id``.
+
+2. **Inbound delivery signature** (connector → gateway): the connector signs
+   each inbound POST with the per-tenant *delivery key*, carried as
+   ``x-relay-timestamp`` + ``x-relay-signature`` headers; the gateway verifies
+   before accepting the event. Mirrors the connector's ``deliverySigning.ts``:
+   ``sig = HMAC_SHA256(f"{ts}.{body_json}", key).hexdigest()`` over the EXACT
+   request body bytes, with a replay-window skew check.
+
+Both schemes use a **multi-secret verify list** (primary first, then a secondary
+during a rotation window), exactly like ``api/src/handlers/stats_oauth.ts`` — so
+a secret rotation doesn't invalidate outstanding tokens.

+"""Gateway-side inbound delivery receiver. EXPERIMENTAL.
+
+The connector delivers normalized inbound events to a tenant's gateway over a
+**signed HTTP POST** (connector ``src/relay/httpGatewayDelivery.ts``), NOT over
+the gateway's outbound ``/relay`` WebSocket: the connector instance that owns a
+platform socket is generally not the instance a given gateway dialed out to, so
+inbound is delivered to a tenant ENDPOINT (which may load-balance across gateway
+instances). Each delivery is HMAC-signed with the per-tenant **delivery key**
+(``gateway/relay/auth.py``); this receiver verifies the signature over the EXACT
+raw request bytes before accepting the event.
+
+Two routes (mirroring the connector's two POST targets):
+  POST {base}            {"type":"message",  "event": <MessageEvent>, ...}
+  POST {base}/interrupt  {"type":"interrupt","session_key": ..., "reason"?}
+
+The receiver:
+  1. reads the RAW body bytes (never a reparsed/re-serialized form — the HMAC is
+     over the literal bytes the connector signed),
+  2. verifies ``x-relay-signature`` / ``x-relay-timestamp`` against the delivery
+     key verify list (primary + secondary during rotation), within the replay
+     window — rejects 401 on any failure,
+  3. parses the JSON and dispatches: a ``message`` to the inbound handler (the
+     RelayAdapter's ``handle_message`` via the transport's normal path), an
+     ``interrupt`` to the interrupt handler.
+
+EXPERIMENTAL: the transport protocol may change without a deprecation cycle
+until ≥2 Class-1 platforms validate it. See docs/relay-connector-contract.md.

+    bind-mount it (``~/.hermes:/opt/data``) so config/sessions/memory persist

+    containerised gateway and a host install share one ``$HERMES_HOME``, a
+    home-scoped stamp is a single slot describing two different installs:
+    the container stamps ``docker`` on every boot, the host install then reads
+    ``docker`` and ``hermes update`` refuses to run ("doesn't apply inside the
+    Docker container") even though the host binary is a perfectly updatable
+    git/pip install. Scoping the stamp to the install tree gives each install
+    its own truthful marker.
+
+    Self-healing for already-poisoned homes: a legacy ``docker`` value in the
+    home-scoped stamp is only honoured when we are genuinely in a container.
+    On a host install that read a contaminating ``docker`` stamp, we fall
+    through to managed/.git/pip detection instead — so existing shared-home

+"""``hermes gateway enroll`` — enroll a self-hosted gateway with a relay connector.
+
+The connector⇄gateway channel is authenticated (the gateway may be
+customer-managed and internet-exposed). This command is the gateway half of the
+zero-touch enrollment in the connector repo's
+``docs/connector-gateway-auth-design.md``:
+
+  1. Resolve a fresh Nous Portal access token from the existing login
+     (``~/.hermes/auth.json``) — the same path ``hermes dashboard register``
+     uses (``resolve_nous_access_token``). This proves *which Nous org (tenant)*
+     the caller owns; the connector derives the authoritative tenant from it via
+     ``GET /api/oauth/account`` (never from anything the gateway asserts).
+  2. POST ``{enrollmentToken, gatewayId}`` to the connector's ``/relay/enroll``
+     with that token in the ``Authorization`` header, over TLS.
+  3. The connector verifies the enrollment token (signature + single-use +
+     tenant match), mints a per-gateway secret, get-or-creates the per-tenant
+     delivery key, and returns both ONCE.
+  4. Persist ``GATEWAY_RELAY_ID`` / ``GATEWAY_RELAY_SECRET`` /
+     ``GATEWAY_RELAY_DELIVERY_KEY`` (+ ``GATEWAY_RELAY_URL`` if supplied) into
+     ``~/.hermes/.env``. The per-gateway secret authenticates the WS upgrade;
+     the per-tenant delivery key verifies signed inbound deliveries.
+
+Managed/hosted installs do NOT self-enroll: the orchestrator (NAS) mints the
+secret directly and stamps it into the container env, so this command refuses to
+run under ``is_managed()`` (mirrors ``dashboard register``).
+
+EXPERIMENTAL: the relay auth scheme may change without a deprecation cycle until
+≥2 Class-1 platforms validate the contract.

+"""Regression for #47967 — empty-name phantom tool calls.
+
+Weak open models (mimo, nemotron-class) that see tool-call XML/JSON sitting in
+file contents or tool output get *primed* and emit their own structured tool
+calls that mimic the payload — usually with an empty/whitespace ``name``. Those
+calls can't be fuzzy-repaired toward a real tool, so the dispatch loop returns an
+error and the model retries. Before this fix, every empty-name error dumped the
+full tool catalog back to the model, which fed the priming loop more names to
+mimic and inflated context 3-4x across the retry budget.
+
+The fix: a blank/whitespace-only tool name gets a terse anti-priming error that
+tells the model in-context tool-call syntax is DATA, with NO catalog dump. A
+genuinely-wrong-but-nonempty name (an actual typo) still gets the full catalog
+so the model can self-correct.
+
+These assert the *behavior contract* of the dispatch branch (what content goes
+back to the model for each name shape), exercised end-to-end through
+``AIAgent.run_conversation`` against an in-process mock provider — not a snapshot
+of the message string.
