            ## RDP Wrapper — Automated INI Release

            | Field | Value |
            |---|---|
            | INI `Updated` date | `${{ steps.meta.outputs.inidate }}` |
            | Published | ${{ steps.meta.outputs.stamp }} |
            | RDPWrapOffsetFinder | ${{ steps.finder.outputs.finder_ver }} |

            ### Assets
            | File | Purpose |
            |---|---|
            | `rdpwrap.ini` | Latest offset database for all known termsrv.dll versions |
            | `RDPWrapOffsetFinder_x64.zip` | x64 finder bundle — extract and run `RDPWrapOffsetFinder.exe` directly |
            | `RDPWrapOffsetFinder_x86.zip` | x86 finder bundle — extract and run `RDPWrapOffsetFinder.exe` directly |
            | `RDPWrapOffsetFinder_x64.exe` / `Zydis_x64.dll` | Loose x64 binaries (used by the installer) |
            | `RDPWrapOffsetFinder_x86.exe` / `Zydis_x86.dll` | Loose x86 binaries (used by the installer) |

            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.
