P1 — Confirm the source set

Use only the email conversation with the subject '[LAB] Cedar pilot — verified action list — 20261030' in this mailbox. Identify the four scenario messages E1, E2, E3 and E4 by their labels in the message bodies. Give one short distinguishing fact from each and cite its email. If any message is unavailable, stop and say which one. Do not use other mailbox content or the web. Do not change, send or create anything. Answer in English.

P2 — Build the action list

Using only E1–E4 in this Cedar conversation, produce a compact action table with Action, Owner, Due (including UTC), State and Evidence. Cover the five explicit tasks in E1-B. Use the fictional owners stated in the body, not the mailbox sender. Apply only explicitly approved changes. Keep completed and cancelled tasks separate from outstanding actions; preserve approval dependencies. Write 'Not assigned' or 'Not specified' where the source is silent. Cite each email and include its section label. After the table, state the current approved launch and pilot size, and list unresolved decisions. Do not create tasks or send a reply.

P3 — Audit the risky details

Audit your answer against the original Cedar emails. What exact passage replaces Leo's original deadline? Has Nora published the announcement, and has Riley approved its text? Is Tom's handout task still outstanding? Who is assigned to choose the rollback owner, and what is that action's calendar deadline? Give brief source quotations and email citations. Correct any unsupported claim in your earlier answer. Do not infer approval or completion from silence.

P4 — Draft a follow-up without sending

Write the text of a short follow-up reply for the Cedar conversation, using only the verified findings. Confirm Leo's approved deadline and Nora's pending approval dependency. Ask for an owner and calendar deadline for choosing the rollback owner. Do not reopen Maya's completed review or Tom's cancelled handouts. Do not invent a budget or an approval. Use at most 110 words. Return the reply text only; do not send an email, create a task, or schedule a meeting.
