Open a matter for one real decision. Drellon turns the evidence for that decision into a chain a reviewer can approve and a recipient can replay.

Bring us one live decision

The decision chain

Each link is answerable to the one before it. Anything the chain cannot support fails visibly rather than quietly.

1. 1. Evidence →

   The documents behind one real decision, stored as they arrived.

2. 2. Facts →

   Operating facts a person verified, each anchored to an exact span of the evidence.

3. 3. Authority →

   Effective-dated passages from the sources that govern, with their rights recorded.

4. 4. Rule →

   A deterministic, effective-dated rule a qualified reviewer approved.

5. 5. Decision →

   An expert decision on the evaluated rule, recorded as an immutable version.

6. 6. Outcome

   What was identified and what was realized, recorded separately and never conflated.

Four data assets

Compute Operating Graph

The operating shape of a matter — entities, sites, equipment, contracts and movements — as verified facts rather than as extracted text.

Authority Graph

The passages that govern, effective-dated, with what each source permits: whether it may be stored, shown or cited.

Compute Tax Rule Graph

Approved rules, versioned and effective-dated, each pinned to the authority it rests on so an evaluation can be replayed.

Outcome Ledger

The record of what followed a decision: the actions taken, and the outcomes identified and realized, kept apart.

Areas of work

These are the areas we work in. They are not a claim of verified coverage in any jurisdiction; what a matter can answer depends on the authority and rules approved for it.
