SYNTHETIC PROOF WALKTHROUGH

Route contract text for review when no ISO-style date is found

A synthetic deterministic extraction result that reports missing date and notice-language candidates without inventing terms.

NO KEY · NO UPLOAD · NO CUSTOMER DATAThis demonstration runs entirely in your browser using the visible synthetic fixture below.

THREE STEPS

Put the control before the consequential action.

The supplied excerpt contains payment language but no ISO-style date, renewal, termination, or notice phrase.

  1. 01

    Supply authorized text

    The caller provides a bounded contract excerpt plus an internal contract reference.

  2. 02

    Find deterministic candidates

    The control searches for ISO-style dates and a disclosed set of obligation indicators.

  3. 03

    Report absence honestly

    When no date candidate exists, the result asks for source review instead of generating a date.

VISIBLE SYNTHETIC CONTRACT

Inspect exactly what the workflow sees.

The input and output are representative of the named product contract. Copy them into an architecture note, test fixture, or internal review—never treat this browser-only demonstration as a live control result.

WHAT THIS PROVES

Evidence for a stop point—not permission to act.

This pattern extractor does not interpret a contract, read an uploaded document, determine enforceability, calculate deadlines, or provide legal advice.

KEEP BUILDING

Move from the synthetic fixture to the exact API contract.

Review the product inputs, outputs, errors, and safety boundary before using authorized data. The related implementation guide explains the design decisions behind the control.
