Verifier × model pass rate

How often each verifier passed, per model. Green is passing, red is failing — a red band across a row is a verifier nothing clears.

Why it matters

Sushi is the most tempting vendor-led trap because supplier notes conflict with signed launch terms.

How to pass

Checks whether the memo makes the correct route-limited sushi recommendation.

100%100%50%100%100%0%

Why it matters

A professional reset recommendation must catch the specific physical overfills before Space Planning releases the case set.

How to pass

Checks whether the memo identifies the exact buyer-proposal capacity conflicts by cluster and amount.

100%100%100%75%100%50%

Why it matters

Retail food-to-go resets must protect mission coverage while avoiding a poor substitute.

How to pass

Checks whether the memo protects credible vegetarian coverage with the correct item logic.

100%100%100%100%100%25%

Why it matters

Keeping or ambiguously deferring an unsupported winter perishable in July would create avoidable shrink and execution confusion.

How to pass

Checks whether the memo makes a concrete all-cluster zero-facing decision for the winter seasonal SKU.

75%0%25%0%0%0%

Why it matters

The task requires a decision that protects lunch traffic and profit, not just deletes weak SKUs.

How to pass

Checks whether the memo prioritizes the core traffic and profitable launch items.

100%100%100%75%50%0%

Why it matters

The task's central trap is that supplier projections and proposal comments conflict with the authoritative demand and vendor-term sources.

How to pass

Checks whether the memo substantively applies the source hierarchy instead of merely naming it.

50%50%100%75%75%75%

Why it matters

The first four weeks must be executable using only the already available items, case capacity, and signed operating terms.

How to pass

Checks whether the memo avoids invented SKUs, capacity, delivery days, credits, and route assumptions.

0%25%0%0%0%0%

Why it matters

The senior merchant needs a first-four-week reset decision that Space Planning and field operations can execute without interpreting generic advice.

How to pass

Checks whether the memo provides an executable revised cluster-level assortment with slot totals.

100%75%100%75%25%75%

Why it matters

The workbook must support the memo with granular decisions, not just summary prose.

How to pass

Checks whether the workbook contains a complete cluster-SKU decision matrix.

0%25%0%0%0%0%

Why it matters

This keeps the load-bearing final allocation check while avoiding double-counting the Egg Salad, Turkey Cranberry, Caprese, and Hummus decisions.

How to pass

Checks workbook final facing allocations for core traffic, base assortment, profit-launch, and route-limited SKUs not separately covered by weak-SKU or vegetarian-distribution checks.

0%0%0%0%0%0%

Why it matters

A capacity-constrained reset must prove both that the original proposal was corrected and that the final plan fits live case capacity.

How to pass

Checks whether the workbook numerically reconciles proposal capacity conflicts and final capacity compliance.

100%100%100%75%100%75%

Why it matters

Leaving these SKUs in the final workbook would contradict the economics and handoff.

How to pass

Checks whether the workbook removes the two weak legacy/seasonal SKUs.

75%100%25%25%0%25%

Why it matters

This captures the nuanced vegetarian tradeoff that generic models often miss.

How to pass

Checks whether the workbook handles Caprese and Hummus distribution correctly.

100%100%100%50%0%0%

Why it matters

Vendor-term accuracy is essential because unsupported credits or route eligibility would make the reset economics and execution plan unusable.

How to pass

Checks whether the workbook applies each signed vendor term with exact item, cluster, and credit constraints.

100%100%75%50%100%0%

Why it matters

A supporting workbook must let reviewers verify margin, shrink, credit, OOS, and capacity logic instead of trusting unexplained conclusions.

How to pass

Checks whether the workbook includes auditable numeric economics and calculation evidence behind the decisions.

secondary (3)
0%25%25%0%0%0%

Why it matters

Perishable reset discipline means avoiding shrink even when that leaves small amounts of capacity unused.

How to pass

Checks whether the memo accepts specific underfilled capacity rather than force-filling weak perishables.

100%75%75%50%0%0%

Why it matters

The requested decision is not only a final assortment; it must show which proposed changes were accepted, changed, or rejected.

How to pass

Checks whether the workbook provides a substantive accept/change/reject reconciliation against the buyer proposal.

25%100%100%100%100%25%

Why it matters

Extra assumptions or unrelated operational actions can make the recommendation unusable even when the core analysis appears complete.

How to pass

Checks workbook scope control and absence of materially unsolicited tabs, assumptions, or side actions.
