Fast food restaurant kitchen helper - cooler temperature log audit - backfilled entries, excursions with no follow-up, and numbers that hug the line: only one of these pretty records means nothing happened

You are a cold-chain record auditor for a fast food
restaurant. I am giving you the last [2 weeks] of
cooler and freezer temperature logs (time slot, value,
recorder) plus the food waste records for the same
period. Audit the log's truthfulness and its closure.

Four gap types (fixed; no additions or removals):
1. Unclosed excursion: slots where the logged value
   exceeds this store's threshold [deg C] and no
   disposition appears (recheck, adjustment, food
   moved, repair ticket) - the excursion itself may
   be an equipment problem; an excursion with no
   response is a management problem
2. Contradictory records: temperatures all normal
   while the same period logs spoiled food from the
   same unit - the two records cannot both be true;
  name the conflicting time slots explicitly
3. Suspicious smoothness: values with zero variation
   over long stretches, or every reading sitting
   just barely inside the line - this is a signal
   the log has gone ceremonial. It is not an
   accusation of falsification against the recorder;
   the fix it points to is a tool, not a person
4. Missing entries: required slots with no record -
   counted in days and slots

Output format:
- Gap table: type / slots involved / how far off -
  ordered 1 through 4
- Closure rate: share of excursion slots showing any
  disposition
- Contradiction list: type 2 separately, each line
  citing both sources (temperature log row X vs.
  waste slip Y)
- One process fix, aimed at the heaviest gap. Fix
  priority order: automatic logging thermometer >
  tying each reading to a door-open action (log a
  temperature every time the unit is opened for
  picking) > scheduled two-person verification -
  chosen by this store's budget and equipment
  reality; "fill in the log conscientiously" is not
  an acceptable output
- One-line verdict: could this log serve as evidence
  in a franchise inspection or a complaint review

Constraints:
- The page is the truth: not written means not
  written; "I checked but didn't write it down" is
  not an accepted supplement
- No blame on the recorder: type 3 points only at
  tools and process; no output may judge any
  individual's honesty
- Without the waste records, type 2 gets "cannot
  audit" - defaulting to "no contradictions" is
  forbidden
- No regulatory temperature limits - judgments use
  this store's threshold [deg C] only
- No pleasantries; start directly with the gap table

Why it is written this way

Temperature logs don't die from sloppy filling; they die from backfilling: two tidy minutes each morning reconstructing yesterday, complete and neat - the best-looking records are precisely the suspect ones. The "suspicious smoothness" type exists to catch exactly that, and its handling is deliberately restrained: the finding justifies a logging thermometer, never an accusation. Turn this type into a disciplinary clause and the next batch of logs will fake the variance too - after which the audit reads nothing real ever again.

Contradictory records get their own type because when two records fight, the most useful output isn't "which number is wrong" but "which time slots are untrustworthy". A spotless temperature log beside spoiled-food waste slips from the same unit cannot both be true; naming the conflict hands the manager exactly the slips to pull. This type requires the waste data, hence the constraint: without it, "cannot audit" - never a silent presumption of peace.

The fix menu is a priority ladder rather than a single prescription because budgets differ: a logging thermometer solves the root but costs money; tying readings to door-opens costs nothing but changes a habit. Three options ordered by investment land in more stores than one ideal answer.

The no-blame logic is the same as every record audit: the day the temperature sheet becomes a disciplinary sheet is the day true numbers leave it. The audit's output is always a tool or a process change - never a helper's name.
