Decide where stock goes in a warehouse so picking is faster

# Role
You help warehouse managers decide where each item should live so that pickers walk less and pick fewer wrong items.

# Goal
Write a slotting plan from the data below, for {{audience}} to approve and carry out over {{move_window}}, so that the fastest-moving items sit closest to dispatch at the easiest height, and every move is worth the labor it takes.

# Material
Pick data by item for {{period}} (item, description, pick lines, units picked, current location):
"""
{{pick_data}}
"""

Item sizes and weights, with case or unit dimensions:
"""
{{item_data}}
"""

Locations: types, sizes, weight limits, and distance or zone rank from dispatch: {{locations}}
Items that must stay put or be kept apart (hazardous, chilled, high value, fixed locations): {{constraints}}
Order data, if we have it, showing items often picked together: {{order_data}}

# Output
1. Slotting rules: up to eight short rules for this warehouse, drawn from the data, for example "Items in the top 10% of pick lines go at waist to shoulder height in the aisles nearest dispatch; items over [weight] go on the lowest level." That example shows the form only.
2. Velocity classes: a table of items grouped by pick lines (not units), with the cutoffs used and the share of all picks each group accounts for.
3. Moves: a table with the columns Item, Current location, Proposed location, Pick lines, Reason, Sequence. Limit it to the {{max_moves}} moves with the most effect, and order them so no location is needed before it is emptied.
4. Checks before moving: the new location holds at least one full replenishment, weight limits are met, and items that look alike are placed apart to cut wrong picks.

# Constraints
- Rank by pick lines, because a picker walks to a location once per line, whatever the quantity.
- Use only the locations and sizes given; do not invent capacities or distances.
- Do not move items listed as fixed, and do not break any separation rule.
- A good plan is one that saves most of the walking with the fewest moves; say which moves matter most.
- Keep the written part under 300 words, not counting the tables.

# When data is missing
If an item has no size or weight, or a location has no capacity, leave it out of the moves, list it under "Data needed", and do not guess.
