# Overview

A protocol's audit should not silently describe yesterday's code.

ContractAtlas compares what is **live on a Soroban network** with what a protocol **declares in a manifest**: the expected WASM hash for each contract and the audit references that list reviewed artifacts. It reports one of four states per contract and renders the same report in a terminal, in CI and (via [contractatlas-studio](https://github.com/Contract-Atlas/contractatlas-studio)) on a public page.

| Status        | Meaning                                                                                                                  |
| ------------- | ------------------------------------------------------------------------------------------------------------------------ |
| `match`       | Live WASM hash equals the declared hash, and an audit lists that hash as reviewed                                        |
| `drift`       | Live hash differs from the declared hash, or matches it but no audit lists it                                            |
| `incomplete`  | Evidence is not enough to compare: no declared hash, no audit, a source-commit-only audit, or a non-WASM executable      |
| `unavailable` | The ledger could not be read, or the instance is not a live entry (archived, expired or undeployed: not distinguishable) |

A failed read is never reported as drift, and a missing artifact mapping is never reported as audited.
