Looking for one ugly workbook case to turn into a fixture

[gregkonush]

I am trying to make the next few Bilig examples come from real workbook-shaped problems instead of more synthetic demos.

If @bilig/headless is almost useful for a Node service, agent tool, import/export job, pricing sheet, payout model, validation workbook, or finance/ops check you have, send one reduced public case here or through the fixture form:

https://github.com/proompteng/bilig/issues/new?template=workbook_fixture.yml

Useful cases are small and boring:

• sheet names, cells, ranges, and formulas
• expected output from Excel, another system, or a manual check
• actual Bilig output or missing API
• one command or script a maintainer can run

Please do not send private customer spreadsheets or confidential business data. Replace names and numbers, keep the formula shape, and make sure the reduced file can become a public test, docs page, example, or corpus fixture.

What I want from this loop: fewer claims, more public proof. If a real blocker turns into a committed fixture, future evaluators can see exactly what was fixed and how to reproduce it.

Narrowing this request a bit: I am especially looking for one reduced ExcelJS-style workbook that has shared formulas or stale cached formula values after a Node service edits inputs.

The useful shape is small:

• one sheet with input rows and repeated formula rows;
• the exact cells ExcelJS reports as sharedFormula or old cached results;
• the expected values after Excel or LibreOffice recalculates;
• the value Bilig gets, or the import/runtime gap that blocks it.

I wrote up the boundary here so the fixture ask is concrete, not a generic "try my library" pitch:

If someone has this failure mode in a private workbook, please reduce the data before sharing. Fake names and numbers are fine; the formula shape is what matters.
