Make flattenSchema preserve JSON Schema semantics.
The map branch skips description, title, and $id by name before it knows whether the map is a schema object or a properties map. Therefore, properties with those names disappear from the comparison.
The leaf-array branch sorts every array, so [1, 2] and [2, 1] under const compare equal even though array order is significant. The scalar branch uses fmt.Sprint, so distinct JSON values such as true and "true" also compare equal.
Track the parent schema keyword. Skip prose only for annotation keywords in schema objects. Sort only arrays whose keyword has unordered semantics. Serialize leaf values with JSON encoding so their types and ordering remain distinct.

…yload Manifest.UnmarshalJSON now resolves the spec version in precedence order: schemaVersion, then tdf_spec_version at the manifest root, then tdf_spec_version under payload. Only non-empty strings count; other values (null is known in the wild) are skipped without failing the decode. The writer still emits schemaVersion only. experimental/tdf aliases sdk.Manifest, so it picks this up too.

Skip non-string values without converting their numbers.
When root tdf_spec_version is 1e400 and payload.tdf_spec_version is "4.3.0", the second decode returns an overflow error before the fallback can select the payload string. Go decodes numbers into any as float64 and returns an error for overflow. The same failure occurs for an object or array containing that number. (raw.githubusercontent.com)
Use json.RawMessage for both candidates. Decode only string candidates and skip other value types. Add a case with an overflowing root number and a valid payload version.
Based on PR objectives, non-string version values must be skipped.

Recognize escaped spellings of the version key.
When the key is "tdf_spec_\u0076ersion", this gate skips the fallback. Go decodes that spelling as tdf_spec_version. The manifest therefore retains an empty version and selects legacy signature encoding, which prevents decryption of a versioned container. The escaped-key case in sdk/manifest_test.go already supplies the triggering input. JSON key matching occurs after escape decoding. (raw.githubusercontent.com)
Remove the literal-only gate, or make it account for escaped keys. Update the test to expect "4.3.0".
Proposed gate correction
- if m.TDFVersion != "" || !bytes.Contains(data, offSpecSpecVersionKey) {
+ if m.TDFVersion != "" {
return nil
}📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Some TDF files record their spec version as
tdf_spec_versioninstead ofschemaVersion, either at the manifest root or underpayload. This SDK only readsschemaVersion, so those files are read as legacy (hex digests) and fail to decrypt.Change: read the version from
schemaVersion, then roottdf_spec_version, thenpayload.tdf_spec_version. Non-string values likenullare skipped. The writer still emitsschemaVersiononly.Reader-only, backwards compatible. Counterparts: opentdf/java-sdk#411, opentdf/web-sdk#1054.
Testing: unit tests for each placement and precedence; end-to-end decrypt with the version under each name.
