sidecar_health

ing.crank/crank · Verify this server

Live reachability probe against the deployed execution sidecar. Thin wrapper around ``sidecar_service.is_configured``/``healthcheck`` -- THE tool that replaces a tester's local ``curl $SIDECAR_URL/health`` (docs/LANE2_DEVNET_VERIFY_RUNBOOK.md Gate C): that curl only proves the TESTER's own shell can reach a sidecar, never whether the DEPLOYED mcp.crank.ing server can -- the exact gap that let the checklist read fully green on 13 Aug 2026 while ``poll_agent_wallet_enable`` was still failing with "managed signing unavailable (sidecar unreachable)". This tool runs the probe from the server's own network path instead. Unconfigured (``SIDECAR_URL`` unset) raises a structured CONFIG_ERROR with NO network attempt -- feature-detected first via ``is_configured``, the same presence-only check ``go_live_status.posture.sidecar.configured`` reads (crank_mcp/services/go_live.py); the two must never disagree. Configured but unreachable returns an OK envelope with ``reachable: False`` -- distinct from "not configured" -- so a caller (or the runbook's Gate C) can tell "we never tried" apart from "we tried and it's down". FREE read, never gated (never in x402 PAID_TOOLS): booleans/counts/hosts only, no secret ever leaves this tool (mirrors go_live.posture's presence-only pattern -- never ``config.SIDECAR_AUTH_TOKEN`` itself).
