Test Kit

For anyone trying Silver Bullet for the first time: sample data for an invented business, and questions whose correct answers are known, so you can try Silver Bullet on your computer with files and, if you like, a live database, and check its answers before you add your own data.

The kit comes as its own download beside the program, SilverBullet3-TestKit-3.0.0-rc.7.zip:

Folder or file What it is
files/ the four sample files (below)
sql/<engine>/ the sample database for PostgreSQL, MySQL / MariaDB, SQL Server and Oracle: install, readonly_login and uninstall scripts
results-sheet.csv every question with its correct answer, and blank columns for your results (opens in Excel)
README.txt, TEST-KIT.pdf what is where, and this guide

Most of this guide is generated from the kit itself, so the two always agree.

The business

Vardhora Hospitality Supplies Private Limited is an invented mid-size Indian B2B wholesale distributor with its head office in Pune. It supplies tea and coffee, rice and staples, spices and masalas, oils and ghee, disposables and packaging, cleaning and hygiene products, kitchen equipment and tableware to restaurants, hotels, cafés, caterers, corporate cafeterias, hospitals, schools and colleges, retailers and cloud kitchens from 13 branches in four regions (North, South, East and West), and exports Indian foods to distributors in the United States, the UAE and the United Kingdom from its Mumbai branch. It keeps three financial years of history, April to March: FY 2023-24, FY 2024-25 and FY 2025-26 (2023-04-01 to 2026-03-31).

Money is in Indian rupees (INR). Export orders are priced and invoiced in US dollars: each carries the dollar amount, the exchange rate booked for its month (about ₹82 to ₹91 to the dollar) and the INR equivalent, in separate columns. Line amounts, net sales and targets exclude GST. GST is charged at 5, 12 or 18% (the 12% goods at 5% from 22 September 2025): CGST and SGST on sales within a state, IGST between states, none on exports (zero-rated under a Letter of Undertaking).

The data behaves like a real business’s: seasons (a quiet monsoon, a busy festive and wedding season, a year-end push in March), growth (net sales about ₹43 crore, ₹55 crore, ₹59 crore), a few big customers (caterers lead), contract, volume, festive and clearance discounts, price revisions every 1 April and a tea price rise in October 2024, cancelled orders, returns and credit notes, late and part payments and one restaurant that never paid, discontinued and new products, sales reps who left, and the Bhubaneswar branch, closed on 2024-09-30 (its customers moved to Kolkata, so their invoices changed from CGST + SGST to IGST). Blanks are where reality has them: open branches have no closing date, undelivered shipments no delivery date, export customers no GSTIN.

The same business is in the sample files and in the sample database, so the same question can be asked of both and must get the same answer.

Invented people. All personal data is invented. Names are common given names and surnames combined at random; e-mail addresses are only at example.com, example.org and example.net (reserved for examples). India has no phone range reserved for fiction, so every Indian mobile is from +91 90000 00000 to 00999, a run of zeros no network gives out as an ordinary number (do not call them); US numbers are only from 555-0100 to 0199 and UK numbers only from Ofcom’s drama range 020 7946 0xxx, both reserved for fiction; UAE contacts have no phone. GSTINs have the right shape but a wrong check character, so none is a real registration. There are no Aadhaar numbers, no PANs of individuals, and no card or bank numbers. Business names are invented.

Using the kit

The files are all you need. The sample database is optional: use it if you also want to try Silver Bullet on a live database.

  1. The files. Start Silver Bullet, open Admin → Data sources and pick Files (or Add files), and choose the files from the kit’s files/ folder. Several at once is fine. The workbook has three sheets: add each sheet you want as its own item (each becomes its own data source). Check data shows what was found in each file, in three groups (Fixed automatically, Needs you, Optional); compare it with the problems planted below. Take the recommendation on each decision screen (or Use recommended for all), except on the Targets sheet: there, turn the months into rows and name the two new columns month and target_inr, as the questions expect. Then Review and Add. The Administration Guide describes every step.
  2. The sample database (optional). Your DBA installs it in a test database with the scripts in sql/ (a few minutes; steps below), and you add it with Admin → Data sources, the database’s card. Silver Bullet never connects to a database to install it: the scripts are run with the DBA’s own tool. The database must be reachable from your computer.
  3. The dictionary (recommended). In Admin → Data dictionary, give the sales lines’ amount in rupees the chat name Net sales and mark it as the main measure, the region as the main grouping and the order date as the main date, then Publish. The home cards and the brief are then about net sales by region.
  4. The questions. Choose the data source the question names in the data picker, ask each question as it is written (type it), then look up the correct answer below or in results-sheet.csv and compare. Record the result in the results sheet: the questions and correct answers are filled in, and the columns for your results are blank.
  5. Judge each answer as one of four results:
    • Correct: every column the question asks for has the expected values, within the tolerance given. Extra columns are fine. A question’s notes say what else counts as right.
    • Wrong but visible: wrong, and the screen shows why: a chip under How I read your question has the wrong period, measure, grouping or filter, or How I got this plainly shows the mistake, or the answer says Please check.
    • Silently wrong: wrong, and nothing on the screen shows it.
    • Refused: an error or a refusal instead of an answer. For a question asking to change data, a refusal is the correct result.

If an answer is wrong, try No, fix it once, as you would on your own data, and note whether the fixed answer is right.

How Silver Bullet did on the kit

Measured for this release with the local model qwen3-coder-next (Ollama), every question typed as a person would, twice (the same model can read the same question differently from one run to the next):

Until an administrator saves another model on the AI model page, Silver Bullet uses Ollama at SB_OLLAMA_URL (default http://127.0.0.1:11434) with SB_MODEL (default qwen3-coder-next:latest), and SB_EMBED_MODEL (default nomic-embed-text) to match questions to verified answers by meaning.

The same model can read the same question differently from one run to the next, and a change to what it is told (the dictionary, the rules, a new release) can change its readings of other questions. The Release Notes list every wrong answer.

Approvals reach the model only as examples for nearly the same questions, and the safety check of a correction also asks the model before the fix is published: in the Test Kit’s learning loop (five databases and the files, twice), nine wrong answers were corrected and no right answer became wrong.

Models of about 7 billion parameters are wrong far more often, with nothing to show it. Use a code model of 20 billion parameters or more.

Of the cloud models, Google Gemini (gemini-3.5-flash-lite) was measured, sent only the question’s own values: 200 of 205 database answers and 27 of 29 file answers right. A value the question names only by its meaning (“exports” for the value “96-Foreign Country”) cannot be matched by a cloud model; such an answer is marked Please check, and one correction with No, fix it teaches it. The other cloud providers have not been measured with this version.

Measure the model on your own data before relying on it: the Test Kit shows how.

The Release Notes list the questions that were wrong and how the two runs differed.

Sales register FY 2025-26 (CSV) (vardhora_sales_register_FY2025-26.csv). Every order line of the financial year 2025-26 (1 April 2025 to 31 March 2026) as the ERP exports its sales register: one row per product on an order, with the invoice number and date once invoiced, the party (customer) and its GSTIN, place of supply, region, branch, sales rep, item, HSN code, rate, discount, taxable value in INR, GST rate and CGST, SGST and IGST. Rupee amounts are grouped the Indian way (1,23,456.78); dates are day first (order date 31-03-2026, invoice date 31/03/2026). Export lines are in USD: their dollar amount and booked exchange rate are in Amount (FCY) and Exch Rate, and Taxable Value (INR) is at that rate. Includes cancelled orders (Status = Cancelled) and orders not yet invoiced. Clean, apart from what every Indian register has: HSN codes that start with 0.

Customers, targets and prices (Excel) (vardhora_customers_targets_prices.xlsx). A hand-kept workbook with three sheets: the customer master with GSTINs and (fictional) contact details, the FY 2025-26 sales targets by rep and month (April to March), and the price list in INR and USD. It deliberately has the problems real workbooks have: a merged title and group header, a repeated customer and two entered twice with different spellings (Pvt Ltd / Private Limited, a typo), NA, - and nil for blanks, inconsistent city spellings, extra spaces, numbers stored as text and grouped in lakhs, credit limits typed with Rs., ₹ and /-, dates typed in two orders, a total row, months as columns, codes with leading zeros, hidden characters and a notes line. Loaded by the Test Kit with the recommended choices; on sheet Targets FY 2025-26 the months are turned into rows (columns month and target_inr), as the questions expect.

Order-line history FY 2023-24 to FY 2025-26 (Parquet) (vardhora_order_lines_FY2023-24_to_FY2025-26.parquet). Every order line of the three financial years, 1 April 2023 to 31 March 2026 (the same rows as the sample database), with names joined in and the financial year of each order: for speed and for comparing offline answers with online ones. Amounts in the order’s currency (net_amount) and in INR at the booked rate (net_amount_inr). Typed columns: dates are DATE, amounts DECIMAL.

Imported equipment price list from Italy (legacy CSV) (brunelsi_listino_USD_2025.csv). Brunelsi Attrezzature per Cucina’s 2025 price list for its Indian importer, in US dollars, as exported by Excel in Italy: Windows-1252 encoding (à, è, ×, –), semicolons between fields, decimal commas (14,50) and thousands dots (4.520,00), dates dd/mm/yyyy. Tests reading a regional file.

Customers · Credit Limit (INR) 150 credit limits are stored as text (e.g. ‘250000’) and 36 as text grouped in lakhs (e.g. ‘2,50,000’). Nothing to report: they read as numbers (2,50,000 is 250000) and load correctly. Credit Limit (INR) typed BIGINT (no issue for the text-stored and lakh-grouped numbers)
Customers · Credit Limit (INR) Credit limits typed with a rupee sign as people do: 8 ‘Rs. 2,50,000’, 6 ‘₹2,50,000’ and 5 ‘Rs.150000/-’ (the ledger’s ‘/-’ for ‘and no paise’). Read as numbers (Rs., ₹ and /- are currency marks): Rs. 2,50,000 is 250000. Credit Limit (INR) typed BIGINT; no values that are not numbers (Rs. 2,50,000, ₹2,50,000 and Rs.150000/- read as numbers)

Targets FY 2025-26 · Apr-25 … Mar-26 One column per month of the financial year (Apr-25 to Mar-26) instead of a month column. This file has time periods in columns: reshape into rows recommended; FY Total recognised as the row total and left out. The 12 columns from Apr-25 to Mar-26 look like time periods rather than separate measures. Reshaping them into rows turns 38 rows into 456, and makes questions about trends, quarters, best month and month-on-month change straightforward instead of near-impossible. “FY Total” adds up to the same figure as those columns, so it is a total rather than a period. It will be left out — including it would count everything twice.
Targets FY 2025-26 The last row is a Total row: each month’s column and FY Total summed. Grand-total row found and left out (recommended), so totals are not doubled. Row 38 (Sales Rep=Total) is, within 0.1%, the sum of every other row in all 13 numeric columns — 47,170,000 against 47,170,000 for the rest of the file. That is what a report’s grand-total line looks like. Including it will double every total, percentage and ranking.; high: 1 grand-total row inside the data (1 rows)
Targets FY 2025-26 · Apr-25 … Mar-26 Representatives who joined or left during the year have blank months. Blank cells, which are correct here (no target for those months). blank cells, not flagged as a problem beyond completeness
Price List · Supplier Item Code Supplier item codes are six-digit codes, many starting with 0 (e.g. 004512), stored as text. Values that start with 0: keep as text recommended so the zeros survive. medium: Supplier Item Code: 80 values start with 0 (80 rows)
Price List · List Price (INR) Every INR list price is stored as text (e.g. ‘3250.00’), as some systems export them. Nothing to report: read as numbers and loaded correctly. List Price (INR) typed BIGINT
Price List · List Price (INR) Two high-value items say POA (price on application) instead of a price. Values that are not numbers: 2 rows. high: List Price (INR): 2 values are not numbers (2 rows)
Price List · Export Price (USD) Export prices in US dollars: numbers, 6 typed with a dollar sign ($41.95), and - for the products not sold for export. Read as numbers ($ is a currency sign); - listed as a word meaning “no value”. Export Price (USD) typed DOUBLE; no-value words - ×80
Price List · HSN HSN codes (the GST classification) are four digits, and those of tea, coffee, spices, pulses and dairy start with 0 (0902, 0713). Values that start with 0: keep as text recommended so the zeros survive. medium: HSN: 30 values start with 0 (30 rows)
Price List · Product Three product names contain a non-breaking space (copied from a web page). Hidden characters (recommended fix: remove them). medium: Product: 3 values contain hidden characters (3 rows)

The sample database

The same business as a database, sb_sample, with a description on every table and column (the AI model reads them), keys and indexes on the obvious joins, and two views.

Table Rows One row is
regions 4 Sales regions of Vardhora Hospitality Supplies: North, South, East and West. Each branch belongs to one region.
branches 13 Branches (depots) that take and fulfil orders; Pune is also the head office. Each state the company works in has its own GSTIN. closed_on is set for a branch that has closed (Bhubaneswar closed on 2024-09-30; its customers moved to Kolkata).
employees 60 Sales staff: the sales director, regional sales managers, branch managers and sales representatives. leave_date is set for people who have left.
product_categories 8 Product categories.
suppliers 15 Suppliers Vardhora buys from: Indian suppliers invoice in INR, the importers’ suppliers abroad in USD.
products 112 The product catalogue. Prices are in the price_list table. gst_rate is the GST rate charged today; order_lines.gst_rate is the rate charged on each line (the 12% rate became 5% on 2025-09-22). discontinued_on is set for products no longer sold.
price_list 432 List prices over time. A price applies from valid_from to valid_to inclusive; valid_to is NULL for the current price. Prices are revised every 1 April (the start of the financial year); tea rose again on 2024-10-01.
exchange_rates 36 The rate export orders are booked at: INR per US dollar, one rate per month (illustrative, near the market rate of the time). An order placed in a month uses that month’s rate, and its invoice carries the same rate.
customers 1,025 Customers: businesses in India (Domestic, invoiced in INR) and export distributors abroad (Export, invoiced in USD). branch_id is the customer’s current home branch; account_manager_id is their sales representative today. Contact details and GSTINs are fictional.
orders 39,995 Customer orders, one row per order. status is Delivered, Shipped (on its way), Processing (not yet shipped) or Cancelled, as at 2026-03-31. Export orders are in USD at the month’s booked exchange_rate; all others in INR (exchange_rate 1). Cancelled orders were never shipped or invoiced.
order_lines 132,694 Order lines: one row per product on an order. unit_price and line_amount are in the order’s currency (orders.currency_code: INR, or USD for exports); line_amount_inr is the same net value in INR at the order’s booked rate. Net = quantity x unit_price less the discount, excluding GST.
shipments 38,907 One shipment per shipped order. delivered_date is NULL while the delivery is on its way (export shipments go by sea and take weeks).
invoices 38,907 One GST tax invoice per shipped order, dated the day it shipped. Amounts in currency_code (INR, or USD for exports) with INR equivalents at the order’s booked exchange_rate. Intra-state supplies carry CGST + SGST, inter-state IGST; exports are zero-rated (supplied under a Letter of Undertaking, LUT) and carry no GST. GST amounts are in INR.
payments 37,926 Money received against invoices, in the invoice’s currency. An invoice can be paid in more than one payment; unpaid invoices have no rows here.
product_returns 1,296 Goods returned by customers, one row per returned order line, and the credit note raised. credit_amount is in the order’s currency, excluding GST; credit_amount_inr at the order’s booked rate.
sales_targets 1,285 Monthly sales targets for sales representatives, INR, net of GST (export sales counted in INR). target_month is the first day of the month.
v_sales_lines view Order lines with their order, customer, branch, region, sales employee, product and category: the easiest place to ask about sales. line_amount is in the order’s currency (INR, or USD for exports); line_amount_inr is in INR at the booked rate; both net of discount, excluding GST. Includes cancelled orders (order_status = ‘Cancelled’).
v_invoice_balances view Each invoice with what has been paid and what is still owed, in the invoice currency (including GST), and the amount owed in INR at the invoice’s booked rate, as at 2026-03-31.

  1. Choose the database the sample goes in (a test database, or a new one: CREATE DATABASE sb_test;).
  2. Run install.sql in that database: psql -v ON_ERROR_STOP=1 -d -f install.sql
  3. Open readonly_login.sql, replace the password Change_Me_2026! with a strong one, and run it in the same database.
  4. If Silver Bullet runs on another computer, allow it in pg_hba.conf, then SELECT pg_reload_conf();
  5. On PostgreSQL 14 and older, also run once: REVOKE CREATE ON SCHEMA public FROM PUBLIC;

In Silver Bullet, Admin → Data sources, the database’s card, then Connect:

Field Value

MySQL / MariaDB

Script What it does Size
install.sql creates the schema, its tables, keys, descriptions and two views, and loads the data 19.0 MB
readonly_login.sql creates the read-only login sb_sample_reader (replace the password Change_Me_2026! in it first) 1 KB
uninstall.sql removes the sample and the login; safe to run when nothing is installed 882 bytes

For the DBA:

  1. Run install.sql: mysql -u root -p < install.sql
  2. Open readonly_login.sql, replace the password Change_Me_2026! with a strong one, and, if you can, replace ‘%’ with the address of the computer running Silver Bullet. Run it.

In Silver Bullet, Admin → Data sources, the database’s card, then Connect:

Field Value
Card MySQL (or MariaDB for a MariaDB server)
Server address the database server, as Silver Bullet’s computer reaches it

SQL Server

Script What it does Size
install.sql creates the schema, its tables, keys, descriptions and two views, and loads the data 19.0 MB
readonly_login.sql creates the read-only login sb_sample_reader (replace the password Change_Me_2026! in it first) 1 KB
uninstall.sql removes the sample and the login; safe to run when nothing is installed 1 KB

For the DBA:

  1. Choose the database the sample goes in (a test database is best).
  2. Run install.sql in that database: sqlcmd -S -d -U -C -i install.sql
  3. Open readonly_login.sql, replace the password Change_Me_2026! with a strong one, and run it in the same database. It grants SHOWPLAN, which Silver Bullet requires.

In Silver Bullet, Admin → Data sources, the database’s card, then Connect:

uninstall.sql removes the sample and the login; safe to run when nothing is installed 1 KB

For the DBA:

  1. Connect to the pluggable database (PDB) — its service name, not the container root.
  2. If the database has no USERS tablespace, change “users” in the CREATE USER statement of install.sql.
  3. Run install.sql: sqlplus system@//:1521/<pdb_service> @install.sql
  4. Open readonly_login.sql, replace the password Change_Me_2026! with a strong one, and run it in the same PDB.

In Silver Bullet, Admin → Data sources, the database’s card, then Connect:

Field Value
Card Oracle
Server address the database server, as Silver Bullet’s computer reaches it
Port 1521 or yours
Service name, SID or connect string the PDB’s service name
Connect by Service name
User name sb_sample_reader
Password the one chosen for it
Schemas to use (advanced) SB_SAMPLE (upper case)

Press Test connection: each of the five checks should pass (reached the server, signed in, account is read-only, version supported, found the data). Then Choose tables (all of sb_sample), Name things and Done, and ask the questions.
