TRANSFORMATION_REPORT.md

Transformation report

This public dataset is a transformed derivative of a private benchmark built from real production accounting records. The transformation is deterministic and applied uniformly across every task, so the accounting relationships survive while no real party, account or transaction is identified.

The real-to-synthetic mapping is not in this directory, is not derivable from anything in it, and is not published.

Design rule

Replace every identity-bearing and externally-correlatable value. Preserve every relationship the accounting depends on.

Concretely, the following are guaranteed to survive the transformation exactly:

• total debits equal total credits, on every task;
• every gold amount remains derivable from a figure visible in the same task;
• quantity x unitCostBasis == costBasis on every tax lot;
• realized gain/loss equals proceeds less relieved basis;
• prices and basis values carry the corresponding monetary and quantity scaling;
• records produced by one on-chain action still share one group identifier;
• the same wallet, entity, counterparty or account is the same synthetic value everywhere it appears;
• word-level links between a counterparty label and an account name - the signal several tasks turn on - are preserved, because tokens are mapped consistently rather than per-occurrence.

Field-by-field

Field / category	Source form	Public form	Method	Reversible from this directory?
Organization	real company name	invented two-word name (ORG-A..ORG-G)	consistent synthetic replacement; assignment order is salt-shuffled so the index carries no ordering information	No
Legal entity	real entity name incl. jurisdiction	invented brand + synthetic Jurisdiction A..H + preserved corporate form (Ltd., Inc., LLC, AG)	consistent synthetic replacement	No
entityType	C-CORP / LLC	unchanged	kept - drives intercompany vs internal-transfer reasoning	n/a
Natural persons	real individuals (lenders, grantees, staff)	role labels: Lender A, Grantee B, Individual C	role-based synthetic replacement; no initials retained	No
Ledger account names	the organization's real chart	accounting-equivalent synthetic names	allowlist rewriting: generic accounting vocabulary passes through, every other token is replaced by a consistent invented token or a role label	No
Ledger account numbers	real GL sequences (4-15 digits)	letter-prefixed synthetic codes (A0001, L0002, I0003, X0004, Q0005)	regenerated per organization, grouped by account type; cannot collide with a numeric source sequence	No
Bank relationships	real institution + partial account number	Bank A..Bank N, partial numbers removed, distinguishing index regenerated, currency retained	synthetic replacement	No
Exchanges / custodians	real venue names	Exchange A..H, Custodian A..D, Prime Broker A..B	synthetic replacement preserving venue role only	No
Exchange enum	the source system's exchangeSourceType	published as recorded, in 23 tasks	retained: it is a public categorical label, and the venue is part of the accounting decision	n/a
Counterparties	real third parties	Market Maker A, Lending Desk A, Validator B, Vendor C, Auditor A, Rewards Distributor A, ...	synthetic replacement preserving the counterparty's economic role	No
Protocol / contract labels	real public protocol names	DEX Protocol A, Staking Protocol B, Bridge A, Multisig Wallet Proxy, Zero Address	synthetic replacement preserving mechanism	No
Wallet addresses	real on-chain addresses	valid-shaped synthetic addresses, format preserved per chain family (0x+40 hex; bech32; base58)	keyed one-way derivation; same source address always yields the same synthetic address	No
Transaction hashes	real on-chain hashes	TXG-00001-style group identifiers	replaced entirely; no hash format and no hash substring is published. Records of one on-chain action share one id	No
Address fragments in names	real address suffixes embedded in wallet/account names	different fragments of the same length and case shape	keyed one-way derivation	No
Name-service handles	real ENS names	<invented>.name	synthetic replacement	No
Asset tickers	real tickers	synthetic tickers with preserved class and derivative structure (st=staked, w=wrapped, br=bridged, av=lending receipt, vd=variable debt, gv=vault share)	consistent synthetic replacement	No
Chains	real chain names	synthetic chain names with preserved L1/L2 and EVM/non-EVM class	consistent synthetic replacement	No
Base-currency amounts	real amounts	rescaled by one global integer factor	exact: an integer factor introduces no rounding, so balance, derivability and gain arithmetic are preserved exactly	No
Token quantities	real quantities	rescaled by a per-asset integer factor	exact: multiplying by an integer cannot add decimal places, so recorded precision and quantityDecimalPlaces stay truthful	No
Unit prices / cost basis	real recorded marks	rescaled with the amounts and quantities they support	prices and basis values carry the corresponding monetary and quantity scaling. Assets held at par keep a par price but are published at reduced precision, so no exact recorded mark is reproduced	No
Fees	real fee quantities and values	rescaled with the same factors as the quantities and amounts they belong to	exact	No
Realized gain/loss	real gains/losses	rescaled by the same global integer factor	exact; gain still equals proceeds less relieved basis	No
Timestamps	real date and time to the second	shifted by one global offset, reduced to minute precision	ordering, intervals, recurrence spacing and tax-lot chronology preserved; the shifted range does not overlap the source range	No
Database identifiers	Mongo ObjectIds, journal/line ids, GL sequence numbers, sync timestamps, template names, provenance	removed entirely	not carried into the export	n/a
Source-system metadata	GL vendor, org database ids, query provenance, internal review status	removed entirely	not carried into the export	n/a
transactionType	the label the source application displays	unchanged	generic vocabulary; carries no identity	n/a
ABI function signatures	standard contract signatures	unchanged for standard signatures (transfer(address,uint256) etc.); non-standard identifiers replaced	universal public signatures, present in millions of contracts	n/a

What deliberately survives

A name built entirely from generic accounting vocabulary is preserved as-is - Treasury, Operating Wallet, Staking Rewards, Vesting, Network Deposits, Locked: R&D + Operations. These phrases are the accounting semantics the benchmark measures; they name no organization, person, place, institution, product or account number, and they occur across the industry. Removing them would destroy the task without improving privacy.

What is deliberately NOT recoverable

The salt, the token map, the address derivation, the numeric factors, the date offset, the asset and chain maps, the task-id permutation, and the mapping from public organization ids to anything real, are all outside this directory. No file here contains a real value, a mapping, a salt, a checksum of a private file, or a pointer to private data.
