Security suite failed (main @ 12c9b63)

Start by running mise run security and inspect the Semgrep finding at line 926 of cdk/src/handlers/linear-webhook-processor.ts, especially the Object.assign(channelMetadata, vaultMetadata(resolved)) call. Reproduce the failure locally, then rerun the same command; done means the security suite succeeds on main or the merge target.

The root mise run security suite failed in GitHub Actions. Use the log tail below and reproduce locally with the same command.
