# Legacy versus new loading model
| Legacy behavior | Legacy evidence | New implementation | Compatibility requirement | Decision | Risk |
|---|---|---|---|---|---|
| Unknown external bootstrap loads `OrthoLoader.dll` | `loading-chain.md` | Bundle bootstrap not selected yet | Identify the workstation/project startup owner first | Defer loading-model decision | High |
| 20 independent DLLs loaded in order | `Settings.xml`, `Loader.cs:63-81` | one entry assembly currently | Preserve required command availability, not the DLL count | Evaluate command/module migration individually | Medium |
| DLLs loaded from UNC | loader location + `Path.Combine` | local smoke bundle only | Decide offline/update policy with operations owner | Do not hard-code UNC in new code | High |
| Settings.xml controls order | `Loader.cs:104-112` | MSBuild/bundle manifest currently | Preserve explicit dependency ordering where behavior requires it | Document, do not emulate blindly | Medium |
| central PluginsOrtho Ribbon | `Ribbon.cs` | new Promhimproekt tab | Preserve actual command mapping where adopted | Separate UI migration decision | Medium |
| project selection uses local app_netload.lsp | `Ribbon.cs:380-405` | no equivalent | Confirm security/project-selection policy | Do not reproduce hidden local control file | High |
| network icons and documents | `Ribbon.cs:330-357`, deployed files | bundle resources | Bundle only licensed, necessary resources | Replace network runtime dependency | Medium |
Recommendation: do not choose AppLoader or a manual-NETLOAD model yet. First identify the missing external bootstrap and confirm whether `app_netload.lsp` is the corporate launcher contract. Once confirmed, use a single versioned entry assembly with explicit manifest/dependency validation; avoid sequential programmatic NETLOAD and UNC execution because the legacy chain is non-atomic and fails the remaining modules after one error.
