Lease portfolio intelligence
Every lease read and reconciled to source: option windows, rent reviews, make-good and outgoings, each answer tied to its clause.
Sourcetrace · document intelligence by Lumen & Lever
Your contracts are full of clocks. They run whether or not anyone is watching.
Sourcetrace is the instrument the AI Verdict’s evidence read runs on. Controlled document intelligence over your organisation’s documents, spreadsheets and operational records. Every answer traces to source.
Private Australian hosting is available. Where it is selected, your data stays in Australia.
Exhibit
Question
When does the option to renew have to be exercised?
Sourcetrace
Written notice must be given no earlier than twelve and no later than six months before the term ends. The term ends 30 June 2027, so the window runs 30 June 2026 to 30 December 2026.

123 Collins Street, Lease.pdf
page 14 · clause 12.2(a)
"The Tenant may renew the Lease by giving the Landlord written notice not less than six (6) months and not more than twelve (12) months before the expiry of the Term."
The gap
An answer you cannot check is an answer you cannot rely on.
General assistants read across your files and return an answer. As a rule they do not show which line produced it.
Tools built for drafting and summarising are fine for drafting and summarising. For a decision that carries liability, the source is the point.
Sourcetrace answers, then shows the clause.
What Sourcetrace does
Three things, and it shows its work on every one.
Reads your material.
Contracts, leases, reports, spreadsheets, correspondence, operational records.
Answers in plain language.
Ask a question, get an answer a board can read.
Traces every answer to source, and watches the deadlines.
Document, page, clause. Nothing asserted without a line behind it, and every dated obligation surfaced before it passes.
Sourcetrace includes the document-structure engine Lumen & Lever uses before model work begins. It preserves layout, tables, annotations and page evidence before anything reaches a model. The controls are set out in the standard.
Technical provenance
The lineage is public.
The structure-preserving approach behind Sourcetrace started as rtfstruct, an open-source parser that reads Rich Text Format as a structured document tree rather than as plain text. That public lineage matters because traceability starts before a model sees the material.
rtfstruct is published under Apache-2.0. Inspect the source repository, cite the archived v0.1.1 release using DOI 10.5281/zenodo.21781834, and read why we built rtfstruct.
Where it applies
The same capability, pointed at the records that carry the risk.
Property
Construction
Contract administration
Every entitlement and claim traced to the clause behind it, with the chronology assembled from the site record.
Bespoke
Document-intensive workflows
Any organisation whose decisions live in contracts, reports, spreadsheets and records. If the work is document-heavy, it is in scope.
Where it is commissioned
Sourcetrace reaches an organisation inside one engagement.
It is not sold on its own. It runs the evidence read inside The AI Verdict, and inside technical due diligence when the price of a company depends on its records.
