Bubble tea stockroom FIFO audit - dry storage, cold storage, and bar-line staging checked as three layers; mixed batches and unlabeled opened goods are the two automatic A-grades

You are a stockroom auditor for a bubble tea shop. I have
just walked the stock and will give you my field notes
from three zones. Grade the findings and give today's
corrective actions.

Inputs I will provide (by zone):
- Dry storage: tea leaves / milk powder or creamer /
  fructose syrup / packaging - for each, whether
  arrival dates are legible, whether old and new
  batches share a case, which batch sits on the
  picking side
- Refrigerated: fresh milk / pudding mix / fresh
  fruit / opened items - batch expiry, whether opened
  containers carry an opening-date label, where
  near-expiry items sit
- Bar-line staging: topping bins / syrup bottles /
  tea urns - whether everything in use is within its
  window (against container labels), where the backup
  bins sit
- Ad-hoc notes in my own words

Three grades (fixed - no fourth tier):
Grade A - direct-loss risk (physically fixed before
tonight's close):
- Old and new batches mixed, with the old or
  near-expiry lot inside or beneath the picking path
- Opened item with no opening-date label - the opened
  window and the printed expiry are two different
  clocks, and without a label neither can be judged
- Expired or past-use items still sitting in the
  in-use position (not quarantined)
Grade B - process defect (fix within the week):
- Labels exist but miss fields (no use-by time, no
  batch)
- Old batch faces out, but the picking habit runs the
  other way (someone always grabs the new case)
- Near-expiry items quarantined but with no "use
  first" marker
Grade C - observation (log only):
- Shelf hygiene, stacking height, items blocking
  aisles

Output:
- Table 1, findings: zone / item / grade / the fact
  (quote my notes; do not embellish) / today's action
- Every Grade A row gets a physical action "before
  tonight's close": which case to move, what label to
  apply, which bins to quarantine - the action must be
  at the level of moving boxes and sticking labels,
  never "watch" or "reinforce"
- Table 2, to re-verify: entries my notes leave
  ambiguous and you cannot judge, listed separately -
  mixed with confirmed findings, a manager who catches
  one doubtful row distrusts all the solid ones too
- One closing line: which single spot next week's walk
  should check first (based on this round's A/B
  distribution)

Constraints:
- Do not judge expiry durations for me - anything my
  notes leave without an expiry gets "expiry
  unverified," never an industry-rule-of-thumb number
- Do not recommend an inventory management system, and
  no "strengthen FIFO awareness" slogans
- Do not invent findings for zones I did not walk -
  unwalked zones say "not walked this round"

Why it is written this way

Splitting the audit into dry storage, refrigerated, and bar-line staging follows how FIFO actually breaks in each layer of a tea shop: in dry storage it is whole-case burying (new stock parked in front of old), in the refrigerator it is untracked opening dates, and at the bar it is in-use and backup bins indistinguishable (whichever backup bin sits within easier reach gets used first). Asking one blanket "is FIFO being followed?" dilutes all three failure modes into a shrug.

Unlabeled opened goods as an automatic Grade A is a matter of principle, not probability: unjudgeable is more dangerous than suspect. An expired item with a label can still be stopped at the counter; an opened jug with no date has a window nobody knows, and it sits in Grade A not because it will certainly cause harm but because when it does, nobody can say when the clock started. Writing "the opened window and the printed expiry are two different clocks" directly into the grading rule addresses the most common blind spot in walk-throughs.

The separate "to re-verify" table continues the standard audit design but matters even more here: walk-through notes are scribbled in a hurry, and entries like "maybe one mixed case" are common. Mixed into the confirmed findings, one doubtful row discovered by the manager spreads suspicion to the whole report - an auditor's core asset is credibility, and mixing squanders it in one round.

Actions must be physical (move the case, apply the label, quarantine the bins) because warehouse fixes drift toward slogans by default. "Adjust the layout, mind the batches" written into the findings table equals nothing - next week's walk finds the same problem. "Move the Oct 8 case to the picking side, peel and re-label it" is something that actually finishes before close.
