            ## RDP Wrapper — Automated INI Release

            | Field | Value |
            |---|---|
            | INI `Updated` date | `${{ steps.meta.outputs.inidate }}` |

            | RDPWrapOffsetFinder | ${{ steps.finder.outputs.finder_ver }} |

            ### Assets
            | File | Purpose |
            |---|---|
            | `rdpwrap.ini` | Latest offset database for all known termsrv.dll versions |
            | `RDPWrapOffsetFinder_x64.exe` | Auto-generates offsets for unknown x64 Windows builds |
            | `RDPWrapOffsetFinder_x86.exe` | Auto-generates offsets for unknown x86 Windows builds |
            | `Zydis_x64.dll` / `Zydis_x86.dll` | Required runtime for the offset finder |

            The installer fetches `rdpwrap.ini` from this release automatically.
            If your termsrv.dll version is not in the INI, the installer downloads the
            offset finder tools and generates the missing section on-the-fly.
