# Legacy P_Rec_Annot loading audit

Scope: read-only inspection of the deployed network directory and the v1.0.4 source checkout. No legacy DLL was executed, copied, or deployed.

The deployed root has 52 files, including 22 managed DLLs. `Settings.xml` enumerates 20 application modules. The inventory and its SHA-256 values are in `deployed-files.csv`; generated report paths use `<deployed-root>` rather than embedding a new runtime configuration path.

High-confidence conclusion: the central loader is `OrthoLoader.dll`. `OrthoLoader.Ribbon.Initialize()` invokes `OrthoLoader.Initialize()`. The latter reads adjacent `Settings.xml` and calls `acDoc.Editor.Command("._netload", fullPath)` sequentially for the configured modules. The bootstrap that initially loads `OrthoLoader.dll` is not present in either audited directory; it remains unknown. Therefore the audit proves same-directory loading, but cannot prove whether an external launcher first NETLOADed the UNC copy or a local copy.

Source-to-binary mapping is `EXACT_SOURCE_MATCH` for 15 deployed DLLs by SHA-256 against `FilesRelease`. Six newer deployed DLLs are `LIKELY_SOURCE_MATCH` by assembly/project identity and metadata but differ byte-for-byte from the checked-in release output. `InsertElevation.dll` is `MULTIPLE_CANDIDATES` because archival projects share the assembly identity.

## Potential test data

| RelativePath | Type | LikelyPurpose | ContainsProjectData | SafeForTest | Reason |
|---|---|---|---|---|---|
| `Template.dwg` | DWG | legacy command template | Unknown | No | Located beside production deployment; no authorization to open or copy it was established. |
| `test.txt` | text | unknown/empty marker | No content | Not useful | Zero bytes. |
| `Справка*.pdf/docx` | documentation | user instructions | Unknown | Review only | Not a CAD fixture. |

No `Project.xml`, `.dcf`, or explicitly labelled sample/demo Ortho DWG was found in the deployed root.
