+### Arc 8 — Post-publish close (operator-confirmed at ~07:00 PST)
+
+After Arc 7's validator extension + serial publish of all four
+transcripts (M.1 @ `7c7c478` → M.2 @ `5dad1b2` → M.3 @ `2007cf3`
+→ M @ `61698af`), driver re-published M with the Arc 7 + §19.2
+candidate #14 + script-edit-disclosure additions (final commit
+`6248f88` on `wiggleverse/ohm-session-history` `main`).
+
+Operator (returned ~07:00 PST, not asleep) confirmed close and
+asked for: (1) the next-session prompt surfaced verbatim in chat
+for easy copy, (2) the transcript updated with this final
+exchange. Driver replied with the prompt printed in full (no
+substantive change from the version embedded in this transcript
+below in the "Prompt the operator can paste…" section; reproduced
+verbatim for ergonomics), then added this Arc 8 + re-published
+per the Session-L "transcript is the final session step" feedback
+memory ("re-finalize if more work happens after").
+
+Final state of this session matches the cut-state table below.
+No code shipped to OHM. Two docs feature branches and three
+ohm-infra/-local proposal/runbook docs are the deliverables that
+become Wave 7's plate.
