- Line 38: Update flattenSchema to track the parent schema keyword and
distinguish schema objects from properties maps, skipping description, title,
and $id only as schema annotations so properties with those names are preserved.
In the leaf-array branch, sort only keywords with unordered-array semantics and
preserve order for const and other ordered values; serialize leaf values with
JSON encoding instead of fmt.Sprint so types 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.

…bers Drop the substring-scan gate on the second decode pass: JSON allows the key to be spelled with escapes, and encoding/json matches it after unescaping, so the gate skipped a key the decoder would have read. Decode both candidates as json.RawMessage and only unmarshal string values. Decoding into any turned a number that overflows float64 into an error that failed the whole decode before payload was read.

Some TDF files record their spec version as `tdf_spec_version` instead of `schemaVersion`, either at the manifest root or under `payload`. This SDK only reads `schemaVersion`, so those files are read as legacy (hex digests) and fail to decrypt. **Change:** read the version from `schemaVersion`, then root `tdf_spec_version`, then `payload.tdf_spec_version`. Non-string values like `null` are skipped. The writer still emits `schemaVersion` only. Reader-only, backwards compatible. Counterparts: opentdf/platform#4060 (Go), opentdf/web-sdk#1054. **Testing:** unit tests for each placement and precedence; end-to-end decrypt with the version under each name. `mvn verify` passes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * The SDK now recognizes manifest versions stored in either the root or payload, while preserving an existing `schemaVersion` when present. * Manifests with missing or null segment sizes now use the corresponding integrity-information defaults; explicit values, including zero, are retained. * Reading alternate version fields and serializing a manifest retains the version under the canonical `schemaVersion` field. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: Paul Flynn <pflynn-virtru@users.noreply.github.com> Co-authored-by: Paul Flynn <pflynn-virtru@users.noreply.github.com> Co-authored-by: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(sdk): read the TDF spec version from all three places, and stop trusting it Read the manifest's spec version in precedence order: schemaVersion at the root, then the non-aligned tdf_spec_version at the root, then tdf_spec_version under payload. Only non-empty strings count; null and other non-string values are skipped without throwing. The resolution lives in resolveSpecVersion. The writer is unchanged and emits schemaVersion only. Stop using that field to choose the integrity-digest encoding. The reader now recomputes the raw digest and accepts the recorded value if it is base64 of the raw bytes or base64 of their hex, for segment hashes and the root signature (digestMatchesRecorded). The assertion signature is checked against both spellings of the assertion hash. The field is unauthenticated and only tracked the encoding because this SDK's writer sets both from one setting; hex is an invertible encoding of the same MAC, so accepting both weakens nothing. Previously a raw-digest file whose version sat only under payload (or was absent) was treated as legacy and failed integrity, as did a hex-digest file that carried a 4.3.0 label. Counterpart of opentdf/platform#4060.

This PR now only widens where the version is read from: root schemaVersion, then root tdf_spec_version, then payload.tdf_spec_version. The resolved version still selects hex vs raw digests, as before.
