- 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.

… 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.

…ault A finding's category no longer comes from a per-code table default that a raise site overrides. The code does not determine which part of a model is at fault: duplicated-error is raised about a type from one place and a relation from five, and invalid-name about a type, a relation and a condition. Each raise site now builds the scoped error itself and the collector reads the category and the metadata back off it, so newScopedCause, the errors.As chain that read the scope back, the category override and errorInfo.Category are all gone. The five scope types implement a ModelError interface with Kind and Scope, which is what makes reading the category off the cause possible. Its unexported method seals it, so those five are the only implementations. WithSentinel supplies the sentinel separately, which keeps errorInfoByType the only place a code's sentinel is decided while the raise site decides the scope. ValidationError.Cause is that interface rather than a bare error. The field a raise site fills in is called part rather than cause. Cause elsewhere in this package means the error a thing wraps: errorInfo.Cause is the sentinel a code implies, ErrRelation.Cause the sentinel a scope holds, ValidationError.Cause the error a finding wraps. This one holds a part of the model and is given its sentinel afterwards, so it is named for what it holds. Severity and ModelErrorKind resolve their wire names through a switch instead of a pair of package-level maps built by an init closure. The reverse direction is written out rather than derived from the forward one, and the wire-name round trip covers every declared value, so the two cannot drift apart unnoticed. unemittedErrorTypes and allErrorTypes are read only by tests, so they live with them. Only the map cost anything in a shipped binary, since a slice of constants is eliminated, but neither belongs in the package's non-test sources. Emitted findings are unchanged. Calling every Raise method, and validating every case in the DSL corpus, produces byte-identical messages, severities, categories, positions, metadata and sentinel matches.

@senojj addressed your comments, feel free to re-review 😄 |
Each validation error is now built by a constructor at the site that detects it and added to ValidationErrors, which is the only sink. The ErrorCollector type and its Raise* methods are gone; position resolution lives in error_construction.go and the constructors in error_builders.go. Output is unchanged: the shared corpora under tests/data still match on message, symbol, error type and position.
The three constructors that took four or more same-typed string arguments now take a named-field struct, so a transposed argument is a compile error rather than a silently wrong message or scope. The remaining constructors put meta before lineIndex, the order the majority already used, so the two trailing pointers no longer differ by constructor.
… the stack Replace the collector-and-bool flow with findings constructed at the point of failure and returned up the stack. - Finding is the wire shape (msg, line, column, file, metadata) with no custom JSON. Findings is both the collection and the error, following go/scanner.ErrorList; Err() is the only place it becomes an error. - Leaf validators take only what they check and return *Finding. The calling phase stamps position (at) and file/module provenance (in), because the caller is what holds the source text and proto metadata. - Kind, the wire errorType, is the single identity axis. The severity/ category/cause classification, its sentinels and table, the error collector, and the engine/options/summary/report types are removed. - Line lookups fold runs of inline whitespace (space, tab, form feed, the lexer WHITESPACE alphabet) so tab-separated declarations resolve. Matching only: columns still resolve against the raw line. Output is unchanged: both shared corpora pass with byte-identical message, errorType, symbol, line and column. BREAKING CHANGE: the exported validation API is now Finding, Findings, Kind, ValidateDSL and ValidateJSON.

The corpus header still said pkg/go attaches severity, category and criticality to each finding and that those expectations live in pkg/go/validation/testdata/severity-category-cases.yaml. The findings refactor removed that classification and that file, so the note described code and a path that no longer exist, in a file shared with pkg/js and pkg/java. The shared-field paragraph above it is unchanged and still correct.
Each validation phase now returns an error rather than appending to a Findings slice. A phase joins its findings with errors.Join, validate joins the phases the same way, and a single joinFindings boundary is the one place a nil *Finding is filtered out. ExtractAllAs[E error] walks the joined error tree and returns every finding in the order errors.Join laid them down, replacing the Findings type and its errors.As recovery. The corpus output is unchanged.

What this does
Restructures Go validation so findings are constructed at the point of failure and returned up the stack, replacing the collector threaded down through every validator.
Findingis one diagnostic; its fields are the wire shape (msg,line,column,file,metadata{…}).Findings []*Findingis the collection and, when non-empty, the error — thego/scanner.ErrorListpattern.ValidateDSL/ValidateJSONreturnnilor aFindings.Kind(the wireerrorType) is the single identity axis.*Finding; the calling phase stamps position and file/module, since it is what holds the source lines and the protoSourceInfo.Removed
The severity/category/cause classification and its table, the sentinels and scoped error types (
pkg/go/errorsreturns to its pre-branch file), the collector, and the engine/options/summary/report types. Severity was one uniform value across every code and nothing consumed the rest; each removed piece can return additively when something emits or consumes it.Output compatibility
Both shared corpora pass with byte-identical message,
errorType, symbol, line and column. Line lookups now fold runs of inline whitespace (space, tab, form feed — the lexer'sWHITESPACEalphabet) so tab-separated declarations resolve; columns still resolve against the raw line.Breaking
The exported surface is now
Finding,Findings,Kind(+ constants),Range,Metadata,ValidateDSL,ValidateJSON.
