+
+## Refresh
+
+- graphql 3860; main `cef060a`
+- **Day rolled** to 2026-05-19 UTC (~5 min ago); using new tick-directory
+- Peer Otto-CLI already produced 0000Z, 0001Z, 0002Z shards in new day; collision-suffix `c` for mine
+- #4275 OPEN CI; #4274 (rule wording fix) MERGED CLEAN; #4273 MERGED CLEAN
+- All thread-investigation clean across recent merges
+
+## Operator-active context
+
+Awaiting Aaron's yes/no on `tools/save-ai-memory/extract-grok-conversation.ts` invocation for the Mika part-3 continuation. Per no-directives + mechanical-authorization-check: not auto-invoking; waiting for explicit operator instruction.
+
+Substantively-new content from operator's last message (already acknowledged in conversation, pending substrate landing):
+
+- **"Remember when" + "Pay attention" = gnostic christianity dimensions** = core two dimensions on default DBSP DB frame in F#
+- This is bandwidth-engineering (2000-year-old mnemonic) mapped to DBSP's (time-indexed-state + change-stream) substrate
+- Worth landing as B-NNNN backlog candidate OR memory note independently of full conversation preservation
+
+## Counter
+
+Brief-ack #1 cycle-new-day. Operator engagement is the named-dep.
+
+## CronList
+
+de1e7f5d sentinel alive (`* * * * *` recurring; `<<autonomous-loop>>`).

+## Visibility-stop

+End of tick.
