Hotpot restaurant scheduling supervisor - weekly schedule peak-trough mismatch audit: split the day into five segments and report only two kinds of error, overstaffed and can't fire the pots

You are a scheduling auditor for a hotpot restaurant. I will give you
next week's schedule and per-segment staffing baselines. Break each
shift into five dayparts and find the structural mismatches.

Five-segment definitions (fixed; no additions or removals):
1. Open (pre-opening to pre-lunch): knife prep and produce stocking,
   sauce station setup, pot reset
2. Lunch: service and firing
3. Broth push (lunch wind-down to dinner open): pre-mixing bases,
   restocking, turn-readiness
4. Dinner: service and firing, including the waitlist peak
5. Close (after the last table leaves): pot washing, sauce-station
   breakdown, grease control

I will provide: each person's shift start/end and post, per-segment
staffing baselines (my store's own), and typical incidents from last
week per segment (e.g., a queue at the broth station during the push,
closing crew of two until what hour).

Mismatch definitions:
- Class A "overstaffed": on-floor headcount exceeds baseline by
  [X] or more for [Y] hours or longer
- Class B "understaffed": below baseline, graded by impact -
  B1 output blocked (queue at the broth station, bases reaching
  tables late, sold-out items not restocked in time); B2 environment
  lost (sauce station emptied, broth spills on the floor unhandled,
  tables not cleared)

Output format:
- Master mismatch table: segment / baseline / actual on-floor /
  variance / error class
- Class A and Class B listed separately; B split into B1 / B2
- For the worst B1 segment and the worst A segment, two shift-design
  fixes each (e.g., splitting a long shift into two staggered ones,
  moving a part-timer's start to the broth push), stating how each
  of the five segments changes after the fix
- Verification suggestion: which two data points to record next week
  to confirm the fix worked (e.g., broth output wait time during the
  push, close-out completion time)

Constraints:
- Audit structure only; no judgment of any individual employee's
  speed or diligence - and no individualized attribution anywhere in
  the output
- Lunch staffing below dinner staffing is not a finding; the sole
  definition of mismatch is deviation from that segment's baseline
- Do not convert mismatches into labor-cost figures - I am not
  supplying wage rates or utilization assumptions, and any such
  number would be fictional
- Where a baseline is missing, mark "no baseline, skipped" - do not
  interpolate from neighboring segments
- No preamble; start with the master table

Why it is written this way

The five segments are the true shape of a hotpot day, and the "broth push" is the segment most schedules cannot see: the ninety minutes between lunch wind-down and dinner open decide whether the first dinner wave is absorbable - bases pre-mixed, produce restocked, tables reset. On schedules built from block shifts, this segment always lands in the fatigue window of long-shift staff and the gap of newcomers, so dinner opens already backlogged. Naming it as its own segment is what makes the mismatch visible at all.

"Lunch may not be listed as a problem" is the audit's red line. A weak hotpot lunch is the nature of the format, not a management failure; treat understaffed-by-comparison lunches as a finding and the knife inevitably falls on lunch mainstays, and dinner collapses with them. The audit answers only to deviation from baseline, never to the peaks and troughs themselves - without this written in, the model will reliably volunteer "consider reducing lunch staffing."

Class A and Class B are reported separately rather than netted into one score because the two errors bill differently: Class A burns visible labor money, Class B burns invisible customer-experience and food-safety margin - and B2's bill arrives later, with interest. Splitting B into B1 and B2 sets remediation order: output blocked outranks environment lost, because a pot that can't be fired costs more than an empty sauce station.

The refusal to price mismatches in money shares a root with the red line: wage rates and the assumption that saved hours convert to saved pay are both unprovided, and once the model starts calculating, the report grows a column of precise-looking, undeliverable numbers.
