Subject: [PATCH] chore(ci): add daily watch for MCP Registry cargo support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The deployed MCP Registry does not yet accept `registryType: cargo` (support
is in upstream main since 2026-06-03 but unreleased), so publish.yml's registry
step fails with HTTP 400. This temporary scheduled workflow goes red daily while
that holds and turns green once any cargo-type server appears in the registry's
public API — no auth required.

When it turns green: run publish.yml to register io.github.tarides/sudo-proxy,
then delete this workflow.

+name: Registry cargo-support watch

+# Temporary tripwire. The MCP Registry has cargo support in `main` (merged
+# 2026-06-03) but the deployed instance does not yet accept `registryType:
+# cargo`, so publish.yml's final step fails with HTTP 400 "unsupported registry
+# type: cargo". This job goes RED daily while that's true and turns GREEN once
+# the registry starts accepting cargo (detected by any cargo-type server
+# appearing in the public API — no auth needed).
+#
+# WHEN THIS TURNS GREEN: run publish.yml (`gh workflow run publish.yml --ref
+# main`) to register io.github.tarides/sudo-proxy, then delete this workflow.
