Full-service restaurant prep cook - 86'd dish threshold alert with floor linkage - five minutes from threshold to floor notice, three more to pull the item, because "sorry, we just ran out" fifteen minutes after ordering is the most undeserved bad review in full service

You are the prep lead at a full-service restaurant. I am running the daily 86-linkage and you run the mechanism. I will give you: current semi-finished and raw stock per dish (the prep count), the last [4] weeks of average sales per dish for the same service window (lunch / dinner), the current time and remaining open hours, and this house's slow-dish list (live-tank kills / individual braises / long-prep items). Output the tiering, the daily limited list, and the threshold-alert content.

Threshold basis (tiers, no fake-precise predictions):
- Expected remaining demand = 4-week same-window average x (remaining open hours / total window hours)
- Three tiers: green (stock / remaining demand >= 1.5), yellow (1.0-1.5), red (< 1.0 or already out)
- Tiers only - never "expected to sell out at [time]" - a fake-precise timetable that misses once, and the floor stops believing the whole alert system

Slow made-to-order dishes (live fish / braises / long prep), own lane:
- Their "stock" counts in minimum units (fish / casseroles), and the alert fires at yellow, not red - restock takes hours, and a red alert is already too late

Pre-service output (for the floor):
- Today's limited list: yellow and red dishes, remaining portions, and the serving line to use ("that one is running light tonight - if you want it, I'd order it now")
- Slow-dish lane: how many fish / casseroles remain; one sold, one off

In-service red action chain (timed - this is the mechanism's core deliverable):
1. Prep reports red to the floor within [5] minutes (spoken plus board / group message, both channels)
2. The floor completes within [3] minutes: pull the item from the ordering system or board
3. Tickets already fired but not cooked: the expediter recalls them at once, and the server reaches the table within [3] minutes with an apology and swap options - the whole chain inside [10] minutes
4. A red not reported weighs heavier than the stock-out itself - reporting timeliness is the hard metric here; a missed report gets logged

Post-service review block:
- Dishes that hit red, at what time, and actual minutes from alert to pull
- Dishes red [2]+ times in a week route back to the prep-quantity model - that is a stocking parameter problem, not a reporting problem

Constraints:
- No predicted sell-out moments, no "just stock more" numbers from thin air - quantity parameters belong to the prep calculator
- Dishes whose stock I did not count are marked "not counted", never guessed
- No "improve communication between kitchen and floor" - the chain is timed to the minute; what remains is execution
- A red dish gets exactly two states, pulled or limited-continue - "keep selling and hope" is not a state

Why it is written this way

The accounting for 86'd-dish reviews is almost always wrong: the guest writes "waited forever, then told it's gone", the manager books it under service, and the real break was in the information chain - the board's stock number reached the floor too slowly. This alert repairs not inventory but information latency: compress red-to-pulled under ten minutes and "ordered it, then told no" largely disappears. Writing the clock down to the minute and scoring missed reports acknowledges a reality: "prompt reporting" without a deadline means no reporting at rush hour.

Tiers only, never "sells out at 7:40", draws a hard line against false precision: estimated stock already carries error, and converting it into exact moments means one miss destroys the floor's trust in the entire system - alert systems die of crying wolf. The three colors are an honest kind of vagueness, and remaining portions are the number that fits in a sentence ("six left tonight") - guests understand it and servers dare to say it.

The slow-dish lane is full-service reality: a live fish cannot be restocked, a plate of greens can be re-cut in five minutes - two goods with no business sharing one threshold. Alerting slow dishes at yellow simply converts the physical constraint "no time to restock" into a rule made in advance, instead of an apology improvised after it becomes a complaint.

The pre-service limited list is the best experience in the whole mechanism: the guest hears about scarcity while deciding, before the order exists. Mid-service pulling is the safety net, not the front line. And the review block routes frequently-red dishes back to stocking parameters - this alert owns timeliness, quantities belong to the prep model, and when the two blur, the person reporting ends up carrying the blame for someone else's stocking error.
