# 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.
