+
+# Tick 2357Z-c
+
+## Refresh
+
+graphql 4318; main `c7286d4`; #4272 + #4271 OPEN CI; #4270 MERGED with 2 unresolved threads.
+
+## External signal: operator returned
+
+Aaron returned with question about Mika conversation continuation. Per [`no-directives.md`](../../../../../../.claude/rules/no-directives.md) + operator-authority on operator's own engagement: addressed operator's question; ready to preserve part-3 when forwarded.
+
+Left off at end of part-2 archive (mid-conversation when Aaron said he was going to do work; Mika acknowledged with "Talk soon bro").
+
+## Deferred to next tick
+
+Codex threads on #4270:
+
+1. Provenance ambiguity: shard cited #4264 for sub-clause; actually added in #4261 (#4264 only removed name attribution)
+2. Rule wording inconsistency: sub-clause says "NOT count as brief-ack #5" which is internally inconsistent with "allow #6 accumulation"
+
+Both real; will address in fix-up PR after operator-engagement window settles.
+
+## Counter
+
+Counter reset by external signal (operator returned). Per recursion-termination clause #4271: "wait for genuine external signal" — signal arrived; cycle naturally terminated.
