Screening

Forgeries keep getting better.Reading harder doesn't scale.

Calyx screens the documents that arrive at your firm and the parties behind them for markers inconsistent with what they claim to be — then reconciles both against records held outside the transaction, by authorities with no stake in it. The finding is sealed as evidence a third party can verify without our help.

The sample
You can fabricate the instrument.
The reference
You cannot fabricate the authority's record of it.
The architecture

Two screens. One reference base.

Almost everything that arrives at a firm is one of two things: a document, or a party. They fail differently, so they're screened differently — but both are struck against the same body of external ground truth.

Screen one

The instrument

Is this document what it claims to be?

Deeds, guarantees, bank letters, proof of funds, notarial certificates, wire instructions, filings, invoices. Screened for markers inconsistent with the class of instrument they claim to belong to, then reconciled against the authority that issued or recorded it.

Screen two

The counterparty

Is this party what it claims to be?

The entity, its registration and standing, the people named as principals, the address, the licensing the claimed activity requires, and whether what the party asserts about itself matches what the registers actually hold.

Corpus sits underneath both

Corpus is the reference base — a versioned, sourced library of what a genuine instrument of each class actually contains, what a legitimate entity's public record actually looks like, and which authority holds the record that settles it. The screens strike the sample. Corpus is what it's struck against. It gets deeper every month, and it doesn't transfer to anyone else.

And when it's both

A wire instruction is a document and a counterparty at the same time. So is a payoff letter, an engagement solicitation, an invoice from a vendor you haven't paid before. Forcing those into one lane is how a screen misses — both run, and the finding carries both sections. Where the classification itself is uncertain, that uncertainty is recorded rather than resolved silently.

The method

Inspection loses. Reconciliation holds.

A convincing forgery defeats a careful reader — that's what makes it convincing. It cannot defeat the registry, the issuing bank, or the court docket, because those records were never the forger's to write. Every criterion pairs what the sample asserts with the record that settles it.

No single marker decides anything. Findings come from convergence — several criteria pointing the same way at once.

01

Instrument markers

Does it behave like the instrument it claims to be — form, tool chain, internal structure, metadata consistent with its stated origin.

Reconciles againstThe issuer's own record. SWIFT for a bank guarantee. The recorder for a deed. The docket for a filing.
02

Entity existence and standing

Does the named entity exist in the jurisdiction it claims, in good standing, with a formation date consistent with the history it asserts.

Reconciles againstSecretary of State and commercial registries. Not the counterparty's own representation.
03

Principals and authority

Do the people cohere — names, titles, credentials, and the authority to sign what they signed. Is anyone identifiable at all.

Reconciles againstBar and licensing registries. Filings naming officers and authorised signatories.
04

Licensing and regulatory record

Where the claimed activity requires a credential, does it exist, is it current, and is it held in this entity's own name. This criterion carries the most weight, because it admits no innocent exception.

Reconciles againstState licensing boards, SAM.gov, FINRA, insurance departments, and the regulator's own record of the relationship claimed.
05

Financial coherence

Do the figures and the shape of the transaction hold together, and which way is capital actually flowing.

Reconciles againstMarket terms for the instrument class. Published fee schedules. Lien and judgment records.
06

Infrastructure forensics

Do domains, headers, routing and telephony match the claimed geography and identity. Does the digital footprint match the claimed operating history.

Reconciles againstRDAP and DNS. The organisation's published channels, obtained independently — never the ones supplied to you.
07

Proof-of-funds integrity

Is the evidence reachable through a channel the counterparty does not control.

Reconciles againstThe holding institution, reached on details you obtained yourself.
08

Sanctions and designation

Does the party appear on a restricted list. Name collisions are common, which is exactly why this one is resolved by a person rather than by a match score.

Reconciles againstOFAC SDN, the Consolidated Screening List, and applicable debarment records.
09

Claim-to-record consistency

What the party or document asserts about itself, set against what the authority recorded. Founding year against registration date. Headquarters against address of record. Scale against filing history.

Reconciles againstEvery register named above, read together rather than one at a time.
10

Behavioural markers

Urgency, secrecy, engineered deadlines, withheld payment instructions, pressure to bypass a step.

Reconciles againstNothing external — read from the interaction itself, which is precisely why it never stands alone.
The readout

Three axes. Never collapsed into one.

How much the markers converge is a different question from how much we could actually reach. Most systems average them into a single score and lose the distinction that matters most.

Fabrication risk

Convergence and weight of the markers present in what was screened. Is this what it claims to be?

File risk

Whether a prudent firm should rely on this for the commitment actually in front of them. A thing can be entirely genuine and still be a bad bet.

Confidence

Completeness of the inputs. What was supplied, what was reachable, what was missing — reported honestly and never blended into the other two.

PROCEED

No disqualifying markers within the scope screened. Not a clearance, and the finding says so.

PROCEED WITH CONDITIONS

Markers present that a stated condition addresses — escrow, payment on delivery, a verified callback on independently obtained details.

CAUTION

Material deviations present. A person has to resolve them before anything is committed.

STANDBY

The screen could not be completed at usable confidence. Not a negative finding — an incomplete one, with the gaps named.

ADVERSE

The evidence runs against what the document or party claims.

Scope is fixed before a verdict is available, and below a confidence floor the only available verdict is STANDBY. A system that will say not yet, and here is what I would need is worth more than one that always produces an answer.

The record

Defensible to a third party, not just persuasive to you.

Every screened document is hashed exactly as received, before anything is done to it. The finding is hashed too. Both go into a provenance record issued alongside it.

Anyone holding a copy can recompute the digest with shasum -a 256 and compare. A match establishes the file is byte-identical to the one screened. A mismatch establishes it is not, without revealing what changed. No key, no software, and no cooperation from Calyx is required — the check is repeatable by a stranger years from now.

Content integrity is fixed; time is asserted. A hash proves what a document contained, not when it existed. Where a qualified time source is required, the record is anchored to an RFC 3161 timestamp authority — and where it is not, the record says so on its face.

An absent record doesn't read as neutral in an exam or a deposition. It reads as whatever the other side argues it means.
The boundary

It flags and verifies. It never adjudicates.

This is the load-bearing constraint, not a disclaimer at the bottom of a page. A screen that renders verdicts about people is one a court, a carrier, or opposing counsel can take apart. One that documents what it found and routes the decision is one they can rely on.

Never determines fraud, guilt, or intent
Never names an individual as a wrongdoer
Never renders a legal, tax, or coverage determination
Never says safe, cleared, certified, or verified
Never treats a channel the counterparty supplied as verification
Never issues a finding without stated scope and stated limits

Every finding is reviewed and released by a named human operator before it is issued. Nothing auto-clears and nothing auto-accuses. Determinations route to the professional who owns them — counsel, the client's own accountant, a licensed broker, or the authorities.

Screening covers commercial entities and the principals named in connection with their business conduct. It is not a background check on individuals, and it is not used for employment, credit, insurance, or housing eligibility decisions.

Where it's used

Before you rely on it.

Screening happens at intake — before the wire, before the closing, before the counterparty becomes a client. Findings are useful afterwards too, but they're cheapest before.

Counterparty onboarding

Corporate records, identity documents, bank references and agreements screened as a set, so the conflicts between them become visible.

Funds and instruments

Proof of funds, bank letters, guarantees and payoff statements — with the channel that produced them treated as part of the evidence rather than as a given.

Title and conveyance

Deeds, notarial certificates and identity evidence, reconciled against the recorded chain and the commission record behind the seal.

Inbound correspondence

Demands, invoices, wire instructions and solicitations — envelope and instrument screened together, since the message carries the document.

Changed payment instructions

The single highest-value trigger. A counterparty already engaged, sending new details — re-screened against the baseline, where the change itself is the finding.

Firms screening for clients

Accounting, legal, title and brokerage firms running intake diligence on behalf of the clients who rely on them, with a record that survives the question later.

Screening runs as a service, or on the node — on hardware the firm owns, behind its own firewall, with confidential material never leaving the building.

Send the one you're not sure about.

A scoped screen on a real document or a real counterparty is the fastest way to see what this produces — the finding, the reasoning, and the record behind it.
