Unsubscribing releases both the subscription and the webhook. It requires a first-party client and the flag `tengu_scalable_quiche`, which is off in this build.\n\n**Details**\n\n- the returned https URL is checked against the expected webhook path shape before being used\n- outcomes are reported as `artifact_durable_subscribe` with reasons including trigger_limit, mint_failed, no_wake_minter and client_policy\n\n**Evidence**\n\n`artifact_durable_subscribe`\n\n- Flag `tengu_scalable_quiche`: Off in both readings (read for one account on one subscription tier against v2.1.227; this account: off, anonymous baseline: off, compiled default: off) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Area: Artifacts\n- Tier: Nothing to try yet\n- Useful: 3\/5\n- Signal: 5\/5\n- Present in the build but not switched on"}
