It exists as its own record because the File ontology is closed and has no field for extracted content, and because a reading has provenance of its own: which model produced it, how confidently, and when. The same file may be read more than once, by different models or at different times, and each reading is a separate record rather than an overwrite — a later reading does not make an earlier one untrue about what was believed then. A FileExtraction is always DERIVED: it is evidence about the file, never a fact about the world, and anything asserted on its basis should reference it.",

Enforce the kind payload matrix.

The schema accepts kind: "ocr" with text: null and kind: "vision" with a string text. Add draft-07 if/then or oneOf branches that enforce the agreed relationship between kind, text, and observations.

Validate the w3ds:// scheme.

fileRef accepts values such as not-a-uri because it only has a string type. This conflicts with the source-file URI contract in Line 34. Add a scheme constraint in the schema and validate the complete vault-specific URI grammar at write time.

Proposed constraint 
     "fileRef": {
       "type": "string",
+      "format": "uri",
+      "pattern": "^w3ds://",

Require or explicitly model missing provenance.

The required array omits model and capturedBy. A valid record can therefore have no model or application attribution. This conflicts with the objective that each extraction retains its own provenance and with the statement that model is needed to revisit stale readings. Require both fields, or make them nullable and define the unknown state.

Proposed required fields 
-  "required": ["id", "kind", "readAt", "fileRef"],
+  "required": ["id", "kind", "readAt", "fileRef", "model", "capturedBy"],

Also applies to: 46-46

schema explicitly defines a nullable unknown state.
