Two follow-on fixes after the MxValueDetails reader correction:
1. AttributeValueDetails was falling through to the package-binary
fallback even when MxValueDetails returned Supported=true. Cause:
`ReadString(direct, "Supported")` reflects on an anonymous type via
InvokeMember, which returned an empty string under
`BindingFlags.IgnoreCase`, making the StringEquals check fail.
Replace with a typed `Type.GetProperty("Supported").GetValue(direct)`
bool check via the new IsDirectSupported helper.
2. ObjectScript (the `scripts get` body retrieval) skipped the live
attribute path entirely and went straight to the package-binary
parser. The parser truncates strings at certain delimiters (e.g.
marker text containing `\n` or `=` came back as just the prefix).
Now ObjectScript tries `obj.ConfigurableAttributes[<script>.<field>]
.value.GetString()` first and only falls back to the package body
when the direct read returns null. Matches the pattern in
AttributeValueDetails. The package fallback survives for cases
where direct GRAccess doesn't surface the attribute.
End-to-end live round-trip on $DelmiaReceiver.ProcessRecipe.ExecuteText
with marker `// scripts-get round-trip marker\nMe.RecipeDownloadFlag = false;`:
scripts get -> Source: direct-graccess
Body: <marker>
attribute value get -> Value: <marker>
Both readers return the same content the writer wrote. Field then
restored to the original `Me.RecipeDownloadFlag = false;`.
Tests still 66/66.

graccesscli
A .NET Framework 4.8 / x86 CliFx-based CLI for automating AVEVA / Wonderware System Platform Galaxy configuration through the ArchestrA GRAccess COM interop library (ZB.MOM.WW.GRAccess.Cli).
Hard constraints
GRAccess is a 32-bit COM stack. Skipping any of these will fail at load or corrupt Galaxy state:
- Target framework / arch:
net48,x86,[STAThread]. No exceptions. - Cannot be loaded from a .NET 10 / x64 process — see
GRAccess-DLL-and-DotNet10-Notes.md. - AVEVA System Platform must be installed locally (or
ArchestrA.GRAccess.dllregistered in the GAC atC:\Windows\assembly\GAC\Archestra.GRAccess\1.7.0.0_23106a86e706d0ae\). The bundled copy inlib/is for build-time reference only. - In daemon mode, every COM call must be marshalled through
Session/StaComThread.cs; calling GRAccess from any other thread will deadlock or corrupt state. - Keep the root
GRAccessAppalive for the lifetime of any derivedIGalaxy/IgObjecthandle. - Mutation flow is fixed:
CheckOut → modify → Save → CheckIn(comment). SkippingCheckInleaves the object locked in the Galaxy repo. - Build requires Visual Studio / MSBuild with the
x86platform target.

Maintenance
Documentation rules live in ../DOCS-GUIDE.md; the root task → tool index lives in ../CLAUDE.md. When adding, renaming, or removing any doc in this folder, update the resource index above in the same change. When the user-facing CLI surface changes, update docs/usage.md (and keep usage.md aligned).
