- As with
ValidateDSL, returningErrorOrNil()here discards a warning/advisory-only collection, leaving JSON callers no value from which to readAllFindings. Preserve findings in the public result (or clearly expose a separate findings-returning API) so non-blocking validation output is not silently lost.
docs/validation/model/TROUBLESHOOTING_GUIDE.md:24 - This troubleshooting row says an unrecognised version produces
invalid-schema-version, while the validator emitsinvalid-schemaand the preceding row already gives that fix. Please identify this slug as currently unemitted so users do not search validation output for a code they can never receive.

- An unrecognised declared version is emitted as
invalid-schema, notinvalid-schema-version(ValidateSchemaVersioncallsRaiseInvalidSchemaVersion, which tagsInvalidSchema). This related-error link therefore directs readers to an unemitted slug instead of the error they will actually see.
- [`invalid-schema-version`](./invalid-schema-version.md) - When the declared version is not recognised
docs/validation/model/README.md:24
- This row still assigns unrecognised versions to
invalid-schema-version, butValidateSchemaVersionemitsinvalid-schemafor them and the linked page now says the same. Keeping this entry makes the error-code index contradict both the implementation and the updatedinvalid-schemarow; mark this slug as currently unemitted (or remove it from the emitted-error table).

ErrorOrNildrops the collection when all findings are warnings/advisories, so callers of this primary entry point receiveniland cannot recover those findings witherrors.As. The new non-blocking classifications are therefore invisible unless callers bypassValidateDSLand know to useValidationEngine/CreateValidationReport. Return findings separately from validity (for example, a result pluserror), or provide a result-returning companion API and make this limitation explicit.
This issue also appears on line 68 of the same file.

- These fields are nonzero on every collector-produced finding, so
omitemptydoes not preserve the old wire shape: JSON now gains bothseverityandcategory(and scoped metadata fields are also newly populated). This contradicts the PR description's breaking-change statement that the wire format is unchanged except for one message. Please update the compatibility/release notes to identify the additive wire change, or avoid emitting these fields if unchanged output is required.
// Severity states whether this finding makes the model invalid. Findings that
// do not block are reported without failing validation.
Severity fgaerrors.Severity `json:"severity,omitempty"`
// Category is the part of the model this finding is about.
Category fgaerrors.ModelErrorKind `json:"category,omitempty"`
pkg/go/validation/errors.go:266
- A collection containing only
nilreportsHasFindings() == true, andCountAllsimilarly counts the nil slot, even thoughBlocksandUnwrapexplicitly define nil as not being a finding. This is reachable through the public constructor,Add(nil), or the exportedErrorsfield and produces contradictory public totals. Filter nil entries consistently (ideally in the sharedfindingsview) or reject them on insertion, and update the test that currently asserts the raw slice length.
// HasFindings reports whether anything at all was reported, blocking or not.
func (e *ValidationErrors) HasFindings() bool {
return len(e.findings()) > 0
pkg/go/validation/multi_file_validation.go:165
- Duplicate type names are represented last-wins in
typeModuleMap, but this loop walks every declaration. If twodocumentdeclarations use different modules, the last module receivesdocumenttwice while the first receives none; the previous map-based implementation listed the logical type once. Deduplicate type names while preserving declaration order soGetModuleInforemains accurate even when inspecting an invalid model.

- Around line 86-97: Update the comment above validateRelationReferences to
state that relation-reference validation runs only when
options.SkipSemanticValidation is false, aligning it with the existing condition
while preserving the explanation of later-phase gating.
- Around line 150-185: Update the summary-building loop in the validation
summary function to increment FindingsBySeverity for every finding, including
those with nil Metadata, before the metadata guard. Keep the existing skip for
metadata-dependent ErrorsByType, ErrorsByFile, and critical-error
classification, preserving the documented total-findings behavior.

… cause Each finding carries a severity, the part of the model it is about, and a sentinel wrapped in a scoped error type, so callers match with errors.Is and errors.As rather than on message text. The shared corpora under tests/data are the contract this is checked against. The runner compares the message exactly, along with the symbol, the error type and both ends of the reported position, and pairs each expected error with a distinct finding. Go now also reads json-validation-cases.yaml, which the JS and Java validators already consume. That runner found the multiple-modules-in-file rule reporting a file's modules in wording of its own, in name order, and without the modules a relation declares. It now collects them as the reference does and reports them in the order the model declares them. Findings that took their order from ranging a map are ordered too, so validating one model twice reports the same list. A malformed condition name is scoped to the condition through RaiseInvalidConditionName: metadata.condition carries the name, metadata.type stays empty, and errors.As yields *ErrCondition. Severity and ModelErrorKind serialise as their wire name through MarshalText and UnmarshalText. A map key needs those methods specifically, since encoding/json consults neither String nor MarshalJSON for a key, and ValidationSummary.FindingsBySeverity is keyed by Severity. BREAKING CHANGE: the validation entry points return error instead of *ValidationErrors, and LineRange/ColumnRange are replaced by a single Range. ErrorCollector.GetErrors is now AllFindings. RaiseInvalidRelationError no longer takes validRelations, RaiseReservedRelationName takes the enclosing type, and SemanticValidator.GetRelationNames is gone. ValidateMultipleModulesInFile and ValidateBasicModelStructure take []FileInfo in place of map[string]map[string]bool. The multiple-modules message text now matches the other SDKs, and a file whose only extra module is declared by a relation now fails validation.

Adds severity, category and typed causes to
pkg/go/validationfindings, via a newpkg/go/errorspackage.Description
What problem is being solved?
errors.Istarget on a finding, so callers matched message text.ErrorMetadata'sType/Relation/Conditionwere declared but never populated.len(errors) > 0.How is it being solved?
pkg/go/errors/sentinels.go, matched witherrors.Is. 5 of them matchpkg/typesysteminopenfga/openfgaby name and by message text.errors.As:ErrObjectType,ErrRelation,ErrRelationCondition,ErrCondition,ErrModel. The first two are field-for-field identical totypesystem.InvalidTypeErrorandInvalidRelationError.Severity(error/warning/advisory, withBlocks()) andModelErrorKind, the scope as a name for consumers that only see JSON. Both are int enums fromiota + 1with anUnspecifiedzero, so a value that was never set cannot pass for one that was.ModelErrorKindalso picks which scoped type wraps the sentinel, so it is not only a serialised label.MarshalText/UnmarshalText, which keeps the names on the wire and the ordinals renumberable. A map key needs those methods specifically:encoding/jsonconsults neitherStringnorMarshalJSONfor a key, andValidationSummary.FindingsBySeverityis keyed bySeverity.error_info.gomaps code to severity, category, cause andCritical: 22 entries for the 22 codes with a raise site, the other 5 declared codes listed inunemittedErrorTypes. A raise site can override the category where one code reaches more than one scope.errors.Aspayload cannot drift.What changes are made to solve it?
offendingTypeemitted fromRaiseInvalidTypeRelation, the raise sitepkg/jssets it at, carrying the enclosing type aspkg/jsdoes. No corpus case asserts that field, so a Go test pins it.RaiseInvalidConditionName:metadata.conditioncarries the name,metadata.typestays empty, anderrors.Asyields*ErrCondition.RaiseInvalidNamewith a nil type had reported it as an object type.HasErrors/Count/GetErrors/ValidationReport.IsValidcount blocking findings;AllFindings/HasFindings/CountAllcount all.criticalErrorTypesfolded into the same table, so criticality and blocking cannot disagree.RunAllValidationsgated later phases on any finding, so one advisory would have skipped duplicate, entry-point, tupleset, complex-operation and wildcard validation. It now counts blocking findings.tests/data/json-validation-cases.yaml, whichpkg/jsandpkg/javaalready consume.multiple-modules-in-filethree ways: Go's own message wording; relation-declared modules never collected, so such a file passed; module list ranged out of amap[string]bool, so it varied per run.Setinsertion and JavaLinkedHashSet. Sorting is deterministic and still fails the corpus. Proto maps carry no order, so relation and condition walks are sorted by name.pkg/go/validation/testdata/severity-category-cases.yaml, not the shared corpus:pkg/javareads that file with a bareYAMLMapperandpkg/jsasserts withtoMatchObject, so a Go-only key breaks both. A test enforces it; the corpus gains a header comment only.docs/validation/modelschema pages rewritten around what is emitted: an unrecognised version reportsinvalid-schemawithinvalid schema 0.9, and a malformedschemaline is a transformer syntax error with no code.
