to a living model of
business commitments.
PostSig LineageAI™ connects the contract record to the business reality it governs. As agreements, orders and business activity change, it maintains the connected understanding teams need to establish what applies and see where it matters.

A connected understanding
of your commitments.
LineageAI is PostSig’s model of business commitments, connecting source evidence, relationships and changes over time to establish what applies.
Our model represents the business context: the products, companies and investments involved, the commitments between them, and the records that establish or change those commitments. This is a structured model of business context, rather than a foundation language model.
Relationship modeling
Understand what changes what.
Represent how a source amends, replaces, supplements or preserves an existing commitment. A new document may affect one provision while other terms continue.
Temporal resolution
Establish what applies at a point in time.
Read effective dates alongside the scope of each change to establish which terms apply together, retaining earlier positions as part of the history.
Evidence lineage
Keep the sources behind the position.
Trace the resulting position to the records that establish or modify it. Preserve the history and make unresolved conditions or missing evidence explicit.
Each change has a scope
and an effective date.
LineageAI connects those changes to the commitments they affect, establishing which terms apply together while preserving the evidence and history behind them.
An amendment may change pricing while other provisions remain intact. A service order may remove a product while separate use conditions continue. The governing position draws on the relevant provisions across those sources.
Your commitments

A few finer points.
What if the records do not support a complete answer?
A conclusion should distinguish what the available evidence establishes from what still needs checking. In the invoice example, a missing billed period prevents the charge from being matched to the applicable service scope. That missing fact stays explicit.
Does a newer document replace everything that came before?
A change may affect only pricing, one service or a particular right. Other provisions continue unless the applicable documents change them. Establishing the current commitment requires reading the relevant sources together.
