Pasted (frozen)
Q1Q2Q3Q4
A pasted number freezes the day you paste it. A Flowsheet token tracks the cell, so the memo is right when the model moves.
Provenance, not guesswork
Every value carries its receipt.
Before anything changes in your document, Flowsheet shows where the number came from: workbook, sheet, cell, and how confident the match is.
- Draft means Flowsheet is proposing a match for your review.
- Ratified means you locked it once, so it is the trusted source.
- You hold the commit. Nothing is written until you say lock.
What you get
Built for people who get audited.
Your ratified dictionary
Every lock you make is saved and reused, so repeat tokens resolve instantly with no second guess.
