domain-facts.json

One dossier per corpus type, with every fact the model holds about it pre-joined: annotations with their written arguments, fields joined to their declared types, operations with their invocations, accesses and throw sites. Written by domain-facts.

No dossier is emitted for a stub type. Field names are those of DomainFacts in packages/analyzer/src/domain-facts.ts.

Top level

Field	Type	Meaning
`kind`	string	always `codegraph.domainFacts/1`
`generatedBy`	string	always `@codegraph/analyzer`
`view`	`ViewDescriptor`	`{name, filters}`
`langs`	string[]	distinct `lang` values in the union, sorted
`framework`	string	the framework profile applied, when one was
`modules`	`ModuleFact[]`	sorted by id
`types`	`TypeDossier[]`	sorted by id
`diagnostics`	object	`types`, `operations`, `invocations`, `accesses`, `throwSites`, and `wiring` when a framework was applied

`modules[]` — `ModuleFact`

Field	Type	Meaning
`id`	EntityId
`name`	string
`types`	EntityId[]	the dossier types this module contains, sorted
`imports`	`ModuleImportFact[]`	`{to, name?, count, external}` — `count` is the base import edges folded into this one

`types[]` — `TypeDossier`

Field	Type	Meaning
`id`	EntityId
`kind`	string
`name`	string
`module`	EntityId	the containing module
`anchor`	`{file, span}`
`loc`	number	gross span length, derived from the anchor
`stereotype`	string	the framework’s own word for what the type is FOR, when a profile said so
`annotations`	`AnnotationFact[]`
`supertypes`	`SupertypeFact[]`
`metrics`	`Record<string, number>`	the extractor’s measures, unmodified; absent means “not measured”
`fields`	`FieldFact[]`
`operations`	`OperationFact[]`
`injectionPoints`	`InjectionPoint[]`	where the container hands dependencies in, with the corpus candidates

`AnnotationFact`

Field	Meaning
`annotation`	the annotation type — normally a stub, its jar being absent
`name`	its simple name, when the model carries one
`module`	the declaring module’s name — what a framework table matches on
`arguments`	`NamedArgument[]`, the written values
`anchor`

`SupertypeFact`

{to, name?, relation, external, provenance} — relation is "inheritance" or "interfaceImplementation".

`FieldFact`

Field	Meaning
`id`, `kind`, `name`
`declaredType`, `declaredTypeName`
`declaredTypeKind`	the declared type’s profile kind (`enum`, `class`, …) — carried, not interpreted
`declaredTypeExternal`
`annotations`
`value`	the declaration-site constant (`Literal`), when the model carries one
`anchor`

`OperationFact`

Field	Meaning
`id`, `kind`, `name`, `signature`, `anchor`
`loc`	gross span length
`entryPoint`	a framework entry-point annotation sits on it (nothing in the corpus calls it)
`annotations`
`metrics`	the extractor’s measures; absent means “not measured”
`invocations`	`InvocationFact[]` — includes facts from nested lambdas and blocks, anchored where they occurred
`accesses`	`AccessFact[]`
`throws`	`ThrowFact[]`

InvocationFact: {to, targetType?, targetTypeName?, targetStereotype?, external, provenance, anchor}. AccessFact: {to, field?, ownerType?, ownerTypeName?, isRead, isWrite, external, provenance, anchor}. ThrowFact: {to, name?, external, provenance, anchor}.

`InjectionPoint`

Present only with --framework. An inference, labelled as one.

Field	Meaning
`id`	the attribute or parameter the container fills
`consumer`	the stereotyped type it belongs to
`declaredType`	the declared type asked for; absent when the model does not say
`via`	`"annotation"` or `"sole-constructor"` — how the point was recognized
`qualifier`	`@Qualifier("x")` / `@Named("x")`, when one narrows this point
`candidates`	corpus implementations the container could supply, sorted; possibly empty
`note`	why the candidate set is empty or narrowed — stated, never silent

An annotation with a written argument, from the same run:

{ "annotation": "java:java.lang.annotation/Retention", "name": "Retention",
  "module": "java.lang.annotation",
  "arguments": [
    { "name": "value",
      "value": { "k": "enum", "type": "java:java.lang.annotation/RetentionPolicy", "name": "RUNTIME" } }
  ],
  "anchor": { "file": "com/acme/order/Audited.java", "span": [7, 7] } }

Deterministic: two runs over one model are byte-identical.
