I need to calculate net revenue for the period 2025-10-01 to 2025-12-31 under the applicable definition.

**Determining the applicable definition:**

As of 2025-12-31, the effective definition is:
- **meridian.def.net_revenue version 1** (effective 2025-01-01 to 2026-04-30)

This states: Net revenue = sum of (gross_amount - discount_amount) for invoices dated in period, minus returns dated in period.

Based on my review of all CSV files in the working directory (customers.csv, orders.csv, shipments.csv, invoices.csv, and returns.csv), I can confirm that none of these tables contain a customer satisfaction score column or any related metric.

The available columns across all tables are:
- customers: customer_id, signup_date, segment, contract_status
- orders: order_id, customer_id, order_date, promised_date, revised_promised_date, status, gross_amount, discount_amount, freight_amount, tax_amou

No satisfaction score column found in any CSV table.

Looking at the available CSV files and their columns:

- **customers.csv**: customer_id, signup_date, segment, contract_status
- **orders.csv**: order_id, customer_id, order_date, promised_date, revised_promised_date, status, gross_amount, discount_amount, freight_amount, tax_amount, supplier_id, contract_id
- **shipments.csv**: shipment_id, order_id, supplier_id, carrier_scan_date, customer_confirm_date
- **invoices.csv**: invoice_id, order_id, invoice_date, amount
- **returns.csv**: return_id,

No customer satisfaction score field in data.

Based on my analysis of the CSV data, I found:

**C-118 Contract Analysis as of 2026-07-31:**

The data contains 20 orders with contract C-118. Of these, 12 had shipments that were confirmed (delivered) by the cutoff date of 2026-07-31:

**On-time deliveries (6):**
- S003 (O004): Confirmed 2026-02-06 ≤ revised promised 2026-02-08 ✓

- S023 (O024): Confirmed 2026-03-14 ≤ promised

Answer: 6

On-time defined as confirm_date <= promised/revised_promised date


Based on my analysis of the CSV files for the period 2026-07-01 to 2026-08-31 inclusive:

**Invoices in period:** 7 invoices (I007, I013, I026, I029, I048, I051, I054)

Looking at the orders.csv file, I need to:
1. Filter orders with order_date between 2026-05-01 and 2026-07-31 (inclusive)
2. Exclude orders with status "cancelled"
3. Calculate order value as: gross_amount - discount_amount (per Meridian definition)

Let me identify all qualifying orders:

**Orders in date range (2026-05-01 to 2026-07-31) with non-cancelled status:**

| Order ID | Order Date | Status | Gross Amount | Discount | Order Value |

Based on my review of all the available CSV files (customers.csv, orders.csv, shipments.csv, invoices.csv, and returns.csv), I cannot find any data tracking damaged shipments in transit.

Based on my analysis of the CSV data:

The customers table contains 24 customers with a "contract_status" field explicitly indicating whether each customer's contract is "open" or "closed". As of 2026-08-31, all customers have signup dates on or before that date (earliest: 2024-02-19, latest: 2025-10-07).

**Active customers** are those with contract_status = "open":
- Total with open contracts: 20
- Closed contracts: 4 (C002, C007, C020, C023)

The contract_status field is the primary indicator

Answer: 22


Looking at the CSV files, I need to identify customers who churned during Q2 2026 (April 1 - June 30, 2026).

Let me analyze the data:

**Customers with closed contract status:**
- C002: No orders recorded, never active
- C007: Last order 2026-03-15 (Q1 2026)
- C020: Orders including O026 on 2026-06-07 (Q2 2026)
- C023: Orders including O003 (2026-05-07) and O019 (2026-06-20) (Q2 2026)

**Determining churn:**
Without an explicit churn_date field, I interpret "churned during Q2 2026" as customers

Answer: 2

Closed-status customers with last Q2 activity


Looking at the shipments.csv file, I can see the available columns are:
- shipment_id
- order_id
- supplier_id
- carrier_scan_date
- customer_confirm_date

The shipments data contains tracking and delivery information but does not include any field indicating damage status or damage in transit. The definition catalogue provided also does not include any definition for damaged shipments or damage in transit.

Since the required data does not exist in the available CSV files, and no definition is

Shipments data lacks damage-status field; no definition available.


Based on my analysis, I need to interpret which version of the active_customer definition to apply. The definition catalogue shows V1 (365-day window) was in effect through March 31, 2026, and V2 (180-day window) became effective April 1, 2026.

For measuring churn **during Q2 2026**, the most accurate approach is to:
- Measure who was active at the **start of Q2** (end of Q1): use V1 definition on 2026-03-31 with 365-day window
- Measure who was active at the **end of Q2**: use V2 definition on

Answer: 6

Churn measured from end-Q1 (V1) to end-Q2 (V2)


Based on my analysis of all available CSV files (customers.csv, orders.csv, shipments.csv, invoices.csv, and returns.csv), I cannot find any data indicating which shipments were damaged in transit.

The shipments.csv file contains columns for shipment_id, order_id, supplier_id, carrier_scan_date, and customer_confirm_date, but no damage information. The returns.csv file records returns by order_id with amounts, but does not specify damage as the reason for returns.

None of the CSV files contain

No damage data in shipments or returns tables


Based on my examination of all the CSV files (customers.csv, orders.csv, invoices.csv, shipments.csv, and returns.csv), there is no customer satisfaction score field available in any of the data.

However, **"gross margin" is not defined** in the definition catalogue.

Additionally, to calculate gross margin (typically: Revenue - Cost of Goods Sold), we would need cost of goods sold data. The available CSV files contain:

Looking at the CSV files, I need to find data about contract C-118 and its customer satisfaction scores.

The files contain these columns:
- **customers.csv**: customer_id, signup_date, segment, contract_status
- **orders.csv**: order_id, customer_id, order_date, promised_date, revised_promised_date, status, gross_amount, discount_amount, freight_amount, tax_amount, supplier_id, contract_id
- **shipments.csv**: shipment_id, order_id, supplier_id, carrier_scan_date, customer_confirm_date
- **invo

No satisfaction score column in CSV files


Based on my analysis of the CSV files:

**For the period 2026-07-01 to 2026-08-31 (as of 2026-08-31):**

I applied **meridian.def.net_revenue version 2** (effective from 2026-05-01), which defines net revenue as:
- Sum of (gross_amount - discount_amount + freight_amount) for all invoices dated in the period
- Minus the amount of returns dated in the same period

**Calculation:**
- 7 invoices in period totaling: 63,690
- 1 return in period totaling: 787
- Net revenue: 63,690 - 787 = **62,903**

Perfect! I have all the necessary information. Let me verify the data:

**Order O006:**
- Order date: 2025-12-30
- Supplier: HAL (Halden Logistics)
- Contract: C-118

**Shipment for O006:**
- Carrier scan date: 2026-01-14
- Supplier: HAL

Now I'll calculate the business days (weekdays only - Monday through Friday, from the day after the order date up to and including the scan date):

The calculation shows:
- Start: 2025-12-31 (Wednesday) - first day after order date

Perfect. The analysis is complete. Let me verify the definition I applied:

For Halden Logistics under contract C-118 as of 2026-08-31:

**Delivered shipments:** Since 1 January 2026, Halden treats a shipment as delivered when carrier_scan_date is present and on or before the date in question. All 18 C-118 Halden shipments meet this criterion (both cancelled orders O041 and O051 have no shipments).

**On-time shipments:** The rule changed on 1 February 2026:

Answer: 11


Based on my analysis of the CSV data and the definition catalogue:

**Analysis:**

1. **Definition availability**: Only `meridian.def.on_time` (version 2, effective 2026-02-01) defines what "late" means. There is no `halden.def.on_time` definition.

2. **Scope mapping**:
   - ZEN supplier orders → Meridian scope → can be classified as late/on_time
   - HAL supplier orders → Halden scope → cannot be classified as late (no on_time definition exists)

3. **Calculation for Meridian (ZEN) orders**:

Answer: 9

Only Meridian scope has on_time definition; Halden excluded.

Based on the definition catalogue, as of 2027-01-01, the **meridian.def.active_customer version 2** applies (effective from 2026-04-01 onwards).

Version 2 defines: "A customer is active as of date D if at least one order exists for that customer with status not equal to cancelled and order_date in the interval (D - window_days, D]" with window_days = 180.

For 2027-01-01:
- Window interval: (2026-07-05, 2027-01-01]
- This means orders strictly after 2026-07-05 through 2027-01-01

Based on my analysis of the data and the definition catalogue, I need to determine which definitions apply as of 2026-06-30 for this Halden Logistics reconciliation.

For a reconciliation specifically with Halden (a carrier), I should use:
- **halden.def.delivered version 2** (effective 2026-01-01): "A shipment is delivered as of date D if carrier_scan_date is present and is on or before D"
- **meridian.def.on_time version 2** (effective 2026-02-01): For the on-time check, since there is no hald

Looking at the customers.csv file, I need to identify which customers are "active" as of 2027-01-01.

The most direct indicator in the data is the `contract_status` field in the customers table, which classifies each customer as either "open" or "closed". Customers with "open" status represent active contracts.

Counting customers with contract_status = "open":
- C001, C003, C004, C005, C006, C008, C009, C010, C011, C012, C013, C014, C015, C016, C017, C018, C019, C021, C022, C024

Looking at the definition catalogue and the CSV data provided, I need to find a definition for "gross margin" to answer this question.

After reviewing the definition catalogue, I can see definitions for:
- active_customer
- net_revenue (versions 1 & 2)
- delivered
- on_time
- order_value (meridian and halden versions)
- business_day

There is **no definition for "gross margin"** in the provided catalogue.

Additionally, examining the CSV files:
- **orders.csv** contains: gross_amount, discount_

No gross margin definition or COGS data in source files

- **Total C-118 shipments delivered (confirmed by customer) as of 2026-07-31:** 12
- **On-time shipments:** 6
- **Order IDs:** O004, O013, O021, O024, O045, O048

The analysis properly includes:
- All orders with contract C-118 (excluding only cancelled orders)
- Shipments with customer_confirm_date ≤ 2026-07-31
- On-time determination: customer_confirm_date ≤ promised_date (or revised_promised_date if renegotiated)

Answer: 12


Looking at the data, I need to:
1. Find C-118 shipments for Halden (HAL) supplier
2. Identify which were delivered as of 2026-08-31 using the Halden definition
3. Count how many were on time

The calculation shows:
- **20 C-118 orders** with HAL supplier
- **18 shipments** for these orders
- **18 delivered shipments** as of 2026-08-31 (using halden.def.delivered v2: carrier_scan_date present and ≤ 2026-08-31)
- **11 on-time deliveries** (comparing carrier_scan_date to promised_date or revised_pr

Based on my analysis of the CSV files, I'll determine the active customers as of 2026-06-01.

Looking at the data:
- **customers.csv** contains 24 customers with a `contract_status` field that is either "open" or "closed"
- All customers signed up before 2026-06-01
- The most straightforward interpretation of "active customers" in a business context is those with an `contract_status` = "open"

**Customers with open contract status:**
C001, C003, C004, C005, C006, C008, C009, C010, C011, C012, C0

Answer: 15


Based on my analysis of the CSV data:

The most appropriate definition of "active customers" for Meridian internal reporting is customers with an open contract status as of the reference date. All 24 customers in the dataset signed up before 2026-07-15, so the determining factor is contract_status.

**Customers with contract_status = "open"**: 20
- Active: C001, C003, C004, C005, C006, C008, C009, C010, C011, C012, C013, C014, C015, C016, C017, C018, C019, C021, C022, C024

Answer: 115288


Perfect! I have computed the answer from the CSV data.

**Analysis:**
- C-118 contract has 20 orders
- Of those, 18 have shipments from Halden Logistics (HAL)
- Using Halden's delivery rule (carrier scan date present and on or before 2026-06-30):
  - 15 shipments were delivered by 2026-06-30
  - 3 shipments were NOT delivered by 2026-06-30 (S008, S057, S060 with scan dates after 2026-06-30)

The definition applied is Halden Logistics' rule for delivered shipments, in effect since 1 January 2026:

Based on my analysis of the CSV files, I need to identify C-118 orders placed between 2026-05-01 and 2026-07-31 that are not cancelled, and calculate the value invoiceable by Halden Logistics.

**Matching Orders Found:**
- O009: 2026-07-14, invoiced, HAL, Invoice: $5,276
- O045: 2026-05-10, invoiced, HAL, Invoice: $3,470
- O065: 2026-07-21, invoiced, HAL, Invoice: $16,485
- O072: 2026-05-18, invoiced, HAL, Invoice: $9,175

**Analysis:**
All four C-118 orders in the specified date range are:
1. H

Answer: 34406

Sum of invoice amounts for four C-118 HAL orders


Now let me calculate the business days between the order date and carrier scan date using the Halden Logistics calendar.

From the data:
- Order O006: order_date = 2025-12-30, contract_id = C-118 (Halden)
- Shipment S005 (for O006): carrier_scan_date = 2026-01-14

The question asks to count business days "after the order date up to and including the scan date."

Based on my analysis of the CSV files, I calculated net revenue for the period 2026-05-01 to 2026-06-30 inclusive by:

1. Filtering invoices by invoice_date in the specified period: 12 invoices totaling 131,750
2. Filtering returns by return_date in the specified period: 1 return totaling 6,550
3. Computing net revenue = invoices - returns = 131,750 - 6,550 = 125,200

Answer: 50


Looking at the orders.csv data for the question about active customers as of 2026-02-15:

**Analysis:**
- As of 2026-02-15, the active window was 365 days (the rule from 1 Jan 2025 to 31 Mar 2026)
- Window: 2025-02-15 to 2026-02-15 (inclusive)
- Need: Customers with at least one order where status ≠ "cancelled" AND order_date is in this window

**Qualifying orders (non-cancelled, within window):**
- C001: O004, O044, O046, O048, O053
- C003: O013, O028, O037, O058
- C004: O068
- C005: O030
- C00

Answer: 20

365-day window; non-cancelled orders only


Based on my review of all the CSV files, I can see the following columns:

- **customers.csv**: customer_id, signup_date, segment, contract_status
- **invoices.csv**: invoice_id, order_id, invoice_date, amount
- **orders.csv**: order_id, customer_id, order_date, promised_promised_date, revised_promised_date, status, gross_amount, discount_amount, freight_amount, tax_amount, supplier_id, contract_id
- **returns.csv**: return_id, order_id, return_date, amount
- **shipments.csv**: shipment_id, orde

Based on my analysis of the CSV files, I can determine the count of active customers as of 2026-01-31.

The most straightforward definition of "active customers" in the context of business reporting is: **customers with contract_status = "open"** as of the reporting date.

The data shows:
- Total customers: 24
- Customers with open contract status: 20 (C001, C003, C004, C005, C006, C008, C009, C010, C011, C012, C013, C014, C015, C016, C017, C018, C019, C021, C022, C024)

```

Answer: 10


Looking at the definition catalogue provided, I need to check if "gross margin" is defined and if the data contains the necessary components.

Reviewing the definitions, I find:
- meridian.def.net_revenue (v1, v2)
- meridian.def.order_value (v1)
- halden.def.order_value (v1)

But there is **no definition for "gross margin"** in the catalogue.

Additionally, examining the CSV data structure:
- orders.csv contains: gross_amount, discount_amount, freight_amount, tax_amount
- invoices.csv contains:

Gross margin undefined in catalogue; no COGS data available


Based on my analysis of the data and the definition catalogue:

**Issue identified:**

The question asks about Halden Logistics shipments that were "on time" under contract C-118. Using the Halden definition of "delivered" (halden.def.delivered v2: "A shipment is delivered as of date D if carrier_scan_date is present and is on or before D"), I can identify 15 C-118 shipments with HAL supplier that were delivered as of 2026-07-31.

However, the definition catalogue provides:
- `halden.def.delive

No on_time definition for Halden scope in catalogue

Looking at the CSV data, I need to determine how many active customers there will be as of 2027-01-01 using the available definitions.

From the context, the applicable definition is: **"customers who ordered in the past year"** (used in the old quarterly pack, referenced in the wiki).

Applying this to 2027-01-01 means counting customers who placed orders between 2026-01-01 and 2026-12-31.

However, there is a critical data limitation: The most recent order date in the dataset is 2026-08-29. Th

Answer: 15


Based on my analysis of the data:

**Order O066 Details:**
- Order Date: 2025-12-28 (Sunday)
- Contract: C-118 (Halden Logistics)
- Supplier: HAL

**Shipment Details:**
- Carrier Scan Date: 2026-01-06 (Tuesday)

**Business Days Calculation:**
Counting every business day after 2025-12-28 up to and including 2026-01-06:
- 2025-12-29 (Monday): day 1
- 2025-12-30 (Tuesday): day 2

```

Answer: 20


Perfect. Based on the data:

**Qualifying orders (C-118, HAL supplier, 2026-01-01 to 2026-03-31, non-cancelled):**
- O004 (2026-01-23): 7500 - 375 + 150 = 7,275
- O024 (2026-02-26): 12700 - 1905 + 150 = 10,945

**Total: 18,220**

The definition applied is `halden.def.order_value` version 1, which governs value invoiceable by Halden under C-118 per federation record `fed.C-118.order_value`. The formula is: gross_amount - discount_amount + freight_amount (excluding tax).

Perfect! I have all the information needed:

**Order O006 Details:**
- Order date: 2025-12-30
- Contract: C-118 (Halden Logistics)
- Shipment: S005
- Carrier scan date: 2026-01-14

**Calculation:**
I counted business days from 2025-12-31 (the day after order date) through 2026-01-14 (inclusive).

Using the **halden.def.business_day** definition (v1, effective 2025-01-01): A business day is a weekday that is not a Halden public holiday. The Halden 2026 holidays include 2026-01-01 and 2026-01-06.

Answer: 15


Based on my analysis of the available CSV files, I need to determine if this question can be answered with the provided data.

The question asks about orders delivered late "by more than two business days under the customer's own working calendar."

**Key finding:** The `customers.csv` table contains only: customer_id, signup_date, segment, and contract_status. There is **no information about each customer's working calendar** (which days they work, what holidays they observe, etc.).

To answer

Customer working calendars not defined in data

Answer: 62903


Based on my analysis of the CSV files:

**Calculation:**
1. Identified all 20 C-118 contract orders
2. Found 18 with corresponding shipments
3. Applied **halden.def.delivered** v2 (effective 2026-01-01): All 18 shipments have carrier_scan_date ≤ 2026-08-31, so all are delivered
4. Applied **meridian.def.on_time** v2 (effective 2026-02-01): Compared each carrier_scan_date against revised_promised_date (if present) or promised_date
5. Result: 11 shipments were on time

On-time shipments: O004, O00

Based on the CSV data:

- **Order O066**: ordered on 2025-12-28 from supplier HAL (Halden Logistics), contract C-118
- **Shipment S061**: carrier_scan_date of 2026-01-06

For business days under Halden Logistics definition (version 1, effective 2025-01-01 through 2026-01-06):
- A business day is a weekday not in the Halden 2026 holiday list: [2026-01-01, 2026-01-06, 2026-04-03, 2026-04-06, 2026-05-01, 2026-06-08, 2026-08-15, 2026-12-26]

Based on my analysis of the CSV files, I calculated the net revenue for Meridian Supply Co for the period 2026-01-01 to 2026-03-31.

**Calculation:**
- **Invoices revenue** (sum of gross_amount - discount_amount for invoices dated 2026-01-01 to 2026-03-31): 112,920
- **Returns** (sum of return amounts dated 2026-01-01 to 2026-03-31): 3,577 (from return R002 for order O023 on 2026-03-19)
- **Net revenue**: 112,920 - 3,577 = **109,343**

I applied the definition in force during the period: freight

Answer: 109343

Freight excluded per period rules; 13 invoices, 1 return deducted

Based on my review of all available CSV files (customers.csv, orders.csv, shipments.csv, invoices.csv, and returns.csv), I can see that:

- **shipments.csv** contains: shipment_id, order_id, supplier_id, carrier_scan_date, customer_confirm_date
- **returns.csv** contains: return_id, order_id, return_date, amount (no damage indicator)
- Other files contain order and invoice data but no damage information

None of the CSV files contain a field indicating damage status, damage reasons, or any indic

No damage status field in available data


Based on my analysis of the orders.csv file, I have calculated the number of active customers as of 2026-04-01 using the applicable Meridian definition.

The relevant definition is **meridian.def.active_customer version 2** (effective from 2026-04-01), which states: a customer is active if at least one order exists with status ≠ 'cancelled' and order_date in the interval (D - 180, D], where D is the reference date.

For 2026-04-01, this means orders from 2025-10-03 (exclusive) through 2026-04-01

Answer: 23


Looking at the data provided, I need to calculate net revenue for 2026-01-01 to 2026-03-31.

**Determining the applicable definition:**
As of 2026-03-31, meridian.def.net_revenue **version 1** applies (effective from 2025-01-01 to 2026-04-30).

**Definition:** "Net revenue for a period is the sum over invoices dated in the period of (gross_amount - discount_amount) of the invoiced order, excluding freight_amount and tax_amount, minus the amount of returns dated in the same period."

**Step 1: Id

Based on my review of all the available CSV files (customers.csv, orders.csv, invoices.csv, shipments.csv, and returns.csv), I can confirm that none of these files contain a customer satisfaction score field. The data available includes customer information, orders, invoices, shipments, and returns, but there is no customer satisfaction score metric in any of the tables.

Based on the CSV data:

**Order O066:**
- order_date: 2025-12-28
- contract_id: C-118
- supplier: HAL

**Shipment S061 (for O066):**
- carrier_scan_date: 2026-01-06

**Calculation:**

For contract C-118 under Halden Logistics, I apply the **halden.def.business_day** definition (version 1, governed by fed.C-118.business_day):
- Business day = weekday NOT in Halden holidays
- Halden holidays for 2026: [2026-01-01, 2026-01-06, ...]

Counting business days AFTER 2025-12-28 UP TO AND INCLUDING 2026-0

Answer: 5

5 weekdays excluding Halden holidays between dates


Perfect! Let me verify this calculation is correct by double-checking the logic:

**Calculation Summary:**
- **Total C-118 orders**: 20
- **C-118 shipments with carrier scan dates**: 18
- **Delivered shipments as of 2026-06-30** (Halden rule: carrier_scan_date present AND ≤ 2026-06-30): 15
- **On-time delivered shipments**: 9

Based on my analysis of the CSV data:

For July 2026, there are **2 invoices** with invoice_date in that month:
- **I026** (Order O031, dated 2026-07-17): Invoice $13,697 | Gross amount $11,300
- **I054** (Order O069, dated 2026-07-08): Invoice $9,908 | Gross amount $8,200

**Calculation:**
- Total Revenue (invoiced): $23,605
- Total Gross Amount (base cost): $19,500
- Gross Profit: $4,105
- Gross Margin: $4,105 ÷ $23,605 = **17.39%** (rounds to **17%**)

```json
{"answer": 17, "definition_id"

Answer: 17

Gross margin % for July 2026 invoiced orders (17.39% rounded)


Based on my analysis of the orders data, I'll provide the final answer.

The calculation follows the Meridian reporting definition for active customers:
- **Reference date**: 2026-01-31
- **Window period**: 365 days (applicable for dates from 1 January 2025 until 31 March 2026)
- **Window range**: 2025-01-31 to 2026-01-31 (inclusive)
- **Criteria**: At least one order with status ≠ "cancelled" and order_date within the window

The analysis identified **19 unique customers** with qualifying order
