Show and tell: five runnable Node workbook automation examples

[gregkonush]

I turned the workflow poll into five runnable @bilig/headless examples for Node services.

They all live in examples/headless-workpaper, run without a browser UI, calculate formulas through WorkPaper, and print deterministic JSON with verified: true after computed readback.

Examples:

• Invoice totals: line totals, subtotal, tax, grand total, and serialized formula readback
  https://github.com/proompteng/bilig/tree/main/examples/headless-workpaper#invoice-totals
• Budget variance alerts: budget vs actual rows, dollar variance, variance percent, and review flags
  https://github.com/proompteng/bilig/tree/main/examples/headless-workpaper#budget-variance-alerts
• Subscription MRR forecast: starting customers, churn, expansion, new customers, and ending recurring revenue
  https://github.com/proompteng/bilig/tree/main/examples/headless-workpaper#subscription-mrr-forecast
• Quote approval threshold: list total, discount amount, quote total, max line discount, and approval status
  https://github.com/proompteng/bilig/tree/main/examples/headless-workpaper#quote-approval-threshold
• Fulfillment capacity plan: forecast orders, required hours, available labor, capacity gap, short days, and status
  https://github.com/proompteng/bilig/tree/main/examples/headless-workpaper#fulfillment-capacity-plan

Try them:

git clone https://github.com/proompteng/bilig.git
cd bilig/examples/headless-workpaper
npm install
npm run invoice-totals
npm run budget-variance
npm run subscription-mrr
npm run quote-approval
npm run fulfillment-capacity

The point is to make service-side spreadsheet logic inspectable: inputs, formulas, computed values, and the verification result are all available as data instead of screenshots.

Feedback I want:

• Which workflow is closest to something you would actually run behind an API, agent tool, job, or CI check?
• Which missing example would make @bilig/headless easier to evaluate in under ten minutes?
• Are the README outputs concrete enough for first-time contributors to add the next example without learning the whole runtime?

Update: I added a search-friendly page for these examples: https://proompteng.github.io/bilig/workbook-automation-examples-node.html

It keeps the clone/run command and current output snippets in one public page, so it is easier to share as a quick eval path outside GitHub.
