The marker now carries the convention's lane-instance suffix + (`work-items:work-loop@`, `work-items:attend-queue@`), so each instance + creates, reads, and edits exactly one comment no sibling can match, and every counter in the + block is per-instance. Earn-trust is re-earned per instance; item-level ratifications still + travel with the item, so only the blanket period-end flag resets. + +### Added + +- **`lane_instance` config key, and an instance-collision check in `work-loop`'s durable state.** + The id defaults to the sanitized lowercased hostname and is validated `^[a-z0-9][a-z0-9-]{0,31}$` + inside the lane's own executable block — it is operator-supplied text interpolated into a shell + string and a `jq` program, so it is rejected rather than sanitized-and-continued. Partitioning is + only correct while ids are distinct, so the state block (now `work-items/loop-state@2`) carries + `lane_instance`, a per-session `writer_nonce`, a per-cycle `heartbeat_at`, and `paused_until`: a + differing nonce over a stale block is the ordinary restart adoption, and a differing nonce over a + *fresh* block means another live lane holds this id — the lane writes nothing, escalates, and + stops. The check runs before any write, so a duplicate id degrades to a stopped lane rather than + a clobbered `first_drain_complete`.
