Day-12 outbound to Jessica on PR #11750 (VEC case study)

Send a single, factual Slack message in the existing #website thread for PR #11750 (VEC /customers/vec case study). Context: PR #11750 is OPEN, mergeStateStatus=DIRTY, reviewDecision=CHANGES_REQUESTED. Last update 2026-06-05. Jessica went silent after the R5 misalignment and tagged Nick. No Day-11 reply came back inbound. Status today is Day 12 of silence. Draft text (use as-is unless Jessica replied inbound between 04:00Z and 14:00Z): "Hey Jessica — quick checkpoint on the VEC case study PR (#11750). Main has moved on this branch since 06-05 so it has merge conflicts now. Two paths whenever you have a minute: (1) I can rebase + re-share a fresh preview if you want to land it, or (2) I can close the PR out if VEC is parked. No rush, just want to make sure it is not stuck because of me. Whichever you prefer." VERIFICATION (acceptance): - Task claims at or after 14:00Z (set run_after). - Message sent via openclaw message tool, exact existing #website thread for #11750 (look up thread_ts in #website history for the VEC PR thread). - result.message_ts recorded. - OR: cancel with result.cancellation_reason if Jessica or Nick replied inbound between 04:00Z and 14:00Z (in that case, do NOT send the boilerplate — respond to their actual message instead). SCOPE: no code changes. Slack only.
