Each earns $96,000 per year ($8,000 per month).\n\nAna and Ben will be backfilled. Each seat stays vacant for 2 months before the replacement starts, and the replacement earns the same salary. Recruiter fee on each backfill: 18% of annual salary.\n\nCho's role is being eliminated and will not be backfilled. Cho leaves Jun 30, so 6 months of salary remain in FY26.\n\nFP&A view: salary only, benefits excluded. Savings are positive; costs are negative.\n\nNotes: the department head says she would 'obviously' want to backfill Cho too. That is not part of the current plan. Cho's severance is handled in a separate forecast line.","rules":[{"type":"plainText"},{"type":"maxWords","max":80},{"type":"maxBullets","max":0}],"promptHints":[{"label":"Names the four lines","patterns":["each backfill","two backfills","no backfill","net for the year"]},{"label":"Gives the fee","patterns":["18%"]},{"label":"Ignores benefits and severance","patterns":["ignore","salary only","benefits"]},{"label":"Bans advice","patterns":["(do not|don'?t).*(say|advice)","facts only"]},{"label":"Caps length","patterns":["\\d+\\s*words","plain"]}],"mistakes":[{"title":"Counting the fee as savings","why":"The AI nets only the vacancy savings and misses the recruiter fee.","fix":"Say: \"Net = vacancy savings minus the recruiter fee (18% of annual salary).\"","checks":["r0"]},{"title":"Treating all three as backfilled","why":"The AI applies the backfill math to Cho.","fix":"Add: \"Cho is not backfilled: remaining months x monthly salary.\"","checks":["r1"]},{"title":"Advising on Cho","why":"The AI recommends backfilling or not.","fix":"Add: \"Facts only.
