Handle a resignation on your team: reply, announcement and cover

Someone on my team has just resigned, and I need to handle the next weeks well: respond to them, tell the team and the people who depend on their work, and make sure nothing important is dropped.

Their role, and what they are leaving for if they said: {{role_and_reason}}
Last day: {{last_day}}
What our company allows me to offer or say (counteroffers, exit interviews, who announces departures): {{company_rules}}

Their main responsibilities, open work and anything only they know how to do:
"""
{{their_work}}
"""

The rest of the team and their current capacity: {{team_capacity}}

Produce, with a heading for each part:
1. A reply to their resignation, under 100 words: thank them, acknowledge the news warmly and suggest a time to plan the handover. It should not argue, guilt them or hint at a counteroffer.
2. A team announcement, under 120 words: that they are leaving, their last day, and how their work will be covered while we plan, with no reasons beyond what they agreed to share.
3. A coverage plan as a table with the columns Work, Risk if dropped (high, medium or low), Who covers it, Handover needed (document, shadowing or introduction), Done by.
4. Five questions for the handover meeting that draw out what is not written down. For example: "Which recurring task would we only notice was missing when something broke?"
5. Next steps for the role: backfill, redesign the role, or spread the work, as options with trade-offs for me to decide.

Keep the whole plan under 600 words.

Do not include the person's reasons for leaving in anything others will read unless my notes say they agreed. Do not offer or promise a counteroffer, pay or title; if our rules allow one, list it in part 5 as an option to discuss with {{my_manager}} first.

If the team cannot cover the high-risk work, say so plainly in part 3 rather than spreading it thin on paper. If I have not said who announces departures, mark part 2 "[CHECK WHO ANNOUNCES]".
