- Design note from the node lane's 30-s propagation reading: a node behind a slow link keeps mining its own chain and the N4 "synced" test cannot see it. New `src/merge.rs` (pure): `not_merging(MergeCheck)` is true when every sink the network reports is more than the merge depth ahead of ours (the node's `params.merge_depth` via igneum_getNodeInfo, else 3,600) and none of our blocks has appeared in the network's view for 120 s, after at least 120 s of mining. Known-failed test first (`a_node_whose_blocks_never_merge_reads_behind_and_holds_the_miner`).
- Engine: every 30 s while mining, the observer's /api/live (600-s window, this machine's lanes marked) gives the network's sink and the newest block of ours it shows (`merge::view_of`); the watch line's decision runs after sync_decision_v2; the state reads "behind" with sync_cause "not merging" and the message "behind: your blocks are not merging into the network"; the miner is held through the existing synced gate; one error event with the gap in blocks. Source owed: peers' own sinks (igneum_getNodeInfo over the peer list) when the node exposes them; the observer is the first view.
- UI: nodeWords' behind case names the cause. 42 UI tests, 172 box tests. Nothing of this on the Mac tonight.
- Decided (main, 7 October 2026, 05:00 UK): `igneum_getPeers` stays on 0.3.19; the observer-based merge check ships in 0.3.18. The Mac check when it takes 0.3.18: the hands moved to the build box at 00:18 UK, so hand node 1 no longer holds 26610; the app, left in external mode, reads "node stopped" and starts its own node only on relaunch (the apply). Check after the apply: own node on 26610/26611, api/state node.mode own, digest_source rpc, synced; the miner stays paused. Read-only; nothing else that night.
