Find shipments by status, creation date range, route, or customer. Returns summaries, newest first. Use this to answer 'where are the late deliveries' or 'what did customer X ship last week' before calling get_shipment for details.

Full detail for one shipment: items, extra charges, total amount, and the complete status history. Use after search_shipments when the summary is not enough.

Public tracking timeline for a shipment: the subset of events a recipient would see, without internal ops notes. Use this when the question is 'where is my package'.

Price a shipment for a route, weight, and product. Resolves the layered rate table (base per route and weight bracket, product override, destination special) and returns the winning rule with the math, plus the price of the other products for comparison.

List outbound manifests (line-haul loads grouped by destination region and date), with shipment counts and total weight. Use for capacity and dispatch questions.

Contents of one manifest: the shipments on it, total weight, and shipment count. Use after list_manifests to see what is on a specific load.

Aggregate delivery performance per route for a period: on-time rate, average transit days, and exception counts. Use for questions like 'which route underperformed last month'. Read-only; fetches up to 1000 shipments.

List customer invoices with amount, due date, and payment status. Use for billing questions like which customers still have unpaid invoices.

Set the status of a shipment. Disabled unless the server runs with ALLOW_WRITES=1; in demo mode the change is kept in memory only. Use only when the user explicitly asks to change a status.
