+Clarion refuses to start the HTTP read API on a non-loopback bind unless **both**
+`serve.http.allow_non_loopback: true` is set **and** an authentication secret is
+resolved at startup — either an HMAC identity secret via
+`serve.http.identity_token_env` (preferred, per ADR-034) or a legacy bearer
+token via `serve.http.token_env`. A non-loopback bind with neither secret
+resolved fails closed at startup with `CLA-CONFIG-HTTP-NO-AUTH`. The
+startup-warning surface (endpoint unauthenticated; protect outside Clarion)
+applies only to the loopback-without-token mode, which remains the ADR-014
+default for the local sidecar case.
 
 **Rationale**: loopback is not a complete security boundary, but accidental
-network exposure is the highest-risk failure mode for the registry-backend
-surface. The guard makes that exposure explicit.

-- **Wardline→Filigree findings are pipeline-coupled through Clarion in v0.1.** Wardline's SARIF output reaches Filigree only via Clarion's `clarion sarif import` translator. This violates pipeline composability for the (Wardline, Filigree) pair. *Retirement condition*: Wardline gains a native Filigree emitter (see Clarion's ADR-015), at which point Clarion's SARIF translator retires and the pair composes directly. The asterisk ships with v0.1 and retires in v0.2.
+- **Wardline→Filigree findings are pipeline-coupled through Clarion in v1.0.** Wardline's SARIF output reaches Filigree only via Clarion's `clarion sarif import` translator. This violates pipeline composability for the (Wardline, Filigree) pair. *Retirement condition*: Wardline gains a native Filigree emitter (see Clarion's ADR-015), at which point Clarion's SARIF translator retires and the pair composes directly. The asterisk ships with v1.0 and is tracked for retirement under `release:v1.1`.
 - **Clarion's Python plugin imports `wardline.core.registry.REGISTRY` at startup.** This is initialization coupling scoped to the Wardline-aware plugin specifically, not to Clarion as a product — Clarion's core and any non-Wardline-aware plugins do not depend on Wardline being importable. The coupling is named so it does not slip unexamined into a future general-purpose plugin. If a future plugin introduces similar initialization coupling without a clear "this plugin is specifically about Wardline" justification, it violates this rule.
 
 Asterisks are acceptable only with a written retirement condition and an honest statement of which failure-test mode is being temporarily violated. A "we'll fix it later" without a test-mode citation is not an asterisk; it is the stealth-monolith failure mode wearing different clothes.
