AllowedValue
valueThe exact string token the wire accepts and returns for this enum value
(the C# enum identifier, e.g. "CompressionOnly"). Use this directly in

[Description] or [Display(Name=…)] on the enum member when present,
otherwise falls back to the enum identifier.

The slave node's degrees of freedom are tied to the master node according to the constraint code. Top-level entity attribute keyed on the slave node — each node can be a slave in at most one constraint.

SG list-format string (e.g. "2,5-7") — already intersected against the
caller's original filter, ready to paste back into POST /job/analysis/run's
loadCases field.
Per-case list of modes the caller requested that did not produce result rows
for that specific case. Each analysed case can compute a different number of
modes, so a flattened across-cases warning would hide gaps. Each entry names
the case and the SG list-format string of missing mode numbers for it.
Informational — to resolve, raise the analysis modes count to at least
the largest missing mode number and re-run.
RegistrationStatus
Outcome of probing the machine for a SPACE GASS registration.
Mirrors the precedence used by desktop SPACE GASS in
NETLicenses\Licenses.vb::RegistrationSetupCheck: legacy SGREG.DAT
short-circuits before any Titan-type probing, then TitanCloud, then Titan LM.
ResourceMetadata
resourceTypeIdentifies entity types managed by the API. Kept separate from SGFileID to allow for future API-only entities that may not have a formal SPACE GASS FileID.

to a property on the read DTO; jsonName matches the JSON key clients see.

SteelCheckSummaryQueryResult
The query result rows.
Warnings returned when some requested load cases or modes did not have analysis results in the response. (Filter Ids that don't exist in the model are rejected up-front with HTTP 400 by the controller — they never reach this DTO.)
casesNotAnalyzed is an SG list-format string that can be pasted straight
into POST /job/analysis/run's loadCases field to re-run only those
cases. modesNotAnalyzed is a per-case list — each analysed case can compute
a different number of modes, so the warning is keyed by case rather than flattened.
