+### Signature Verification (Modern VDMs)
+
+Recent engine builds perform WinTrust catalog verification for VDM files. This
+project now routes `WinVerifyTrust`/`CryptCAT*` to an external verifier and
+fails closed if verification cannot be performed.
+
+By default, `mpclient` will execute `./tools/wintrust-verify`, which tries
+`osslsigncode verify` first, then `signtool`. You can override the verifier by
+setting `MPENGINE_VERIFY_HELPER` to any binary/script that accepts:
+
+```
+--file <path> [--catalog <path>]
+```
+
+Environment variables:
+* `MPENGINE_VERIFY_HELPER`: Path to a custom verifier helper.
+* `MPENGINE_CATALOG_DIR`: Directory to search for `.cat` files (default `engine`).
+* `MPENGINE_CATALOG_PATH`: Explicit catalog path to use.
+* `MPENGINE_CA_FILE`: CA bundle for `osslsigncode` verification.
+* `MPENGINE_CRL_FILE`: CRL file for `osslsigncode` verification.
+
 There are some other sample tools, `mpstreamfuzz` and `mpscript`.
