I was wrong. AVEVA Tech Note 537 ("Creating an Application Object Script
Using GRAccess", April 2008) documents the supported pattern:
ConfigurableAttributes[<script>.<field>].SetValue(MxValue) inside a
CheckOut/Save/CheckIn cycle. graccesscli's existing
FindAttributeForMutation already follows this — writes to MxCategoryPackageOnly_Lockable
script-text fields persist correctly.
The earlier "writeback gap" diagnosis was a phantom caused by a reader-side
issue. `object attribute value get` against a script body returns
"Supported: False / Attribute value is not exposed" because
MxValueDetails uses a case-sensitive `ReadProperty(attr, "Value")` lookup
plus an accessor probe (GetBoolean -> GetInteger -> GetFloat -> GetDouble
-> GetString) that can fall through silently for some MxValue shapes. The
COM-side property is exposed as `value` (lowercase), readable as
`attr.value.GetString()` -- which the live probe at
`analysis/ide-edit-investigation/probe_setvalue/` does and confirms the
post-write content matches the marker exactly.
Live verification on $TestMachine.UpdateTestChangingInt.DeclarationsText
and $DelmiaReceiver.ProcessRecipe.{ExecuteText,DeclarationsText}:
=== verdict ===
marker landed on same-proxy ConfigurableAttributes: True
marker landed on same-proxy Attributes : True
marker landed on fresh-proxy ConfigurableAttributes: True
marker landed on fresh-proxy Attributes : True
The probe also confirmed that two earlier graccesscli `object scripts set`
invocations (which I had wrongly believed failed) had persisted -- the
marker text I wrote previously was still on disk in
ProcessRecipe.{ExecuteText,DeclarationsText} when read directly via
attr.value.GetString(). The probe restored both fields to their original
values.
This commit:
- Updates the misleading [Command(...)] / [CommandOption(...)]
descriptions in GRAccessSurfaceCommands.cs back to honest versions
citing TN-537.
- Restores the --file-using examples for `object scripts set` and
`object scripts create` across script-editing.md, llm-integration.md,
usage.md, and zb-testmachine.md.
- Removes the test that asserted the (wrong) EnsureMutableViaSetValue
guard. Re-aims ScriptCommandDescriptions_… at the corrected wording.
- Removes two leftover EnsureMutableViaSetValue calls in the trigger-period
/ trigger-type write paths (both targeted MxCategoryWriteable_C_Lockable
attributes; would never have fired even if the helper still existed).
- Adds analysis/ide-edit-investigation/REPORT.md (replacing the earlier
wrong report) plus the probe sources under probe_setvalue/.
The MxValueDetails reader gap (case-sensitive ReadProperty + accessor
probe) is a real follow-up: `object attribute value get` should
case-insensitively read `value` and try GetString first when the
underlying MxValue.DataType is MxString. Out of scope here -- that's a
separate, smaller fix.
Test count delta: 67 -> 66 (-2 wrong tests, +1 corrected description test).
