existing verification and Stellar CLI provenance entries, so the v0.2.3
artifacts are traceable to their contract source.

binding definitions, preserving the existing contract and code mapping
structure.
- Around line 105-106: Update the error classification logic in the parser
around the SOROBAN_CONTRACT_ERRORS lookup so generic numeric codes are not

In `@src/stellar/router-client.ts`:
- Around line 368-371: Update the method containing the coreId lookup and
void_stream call to load the complete NFT stream data, verify its type is
GeneratedStreamType.Flow, and reject Lockup tokens before invoking void_stream;
only convert and pass the core ID after this validation.
In `@src/stellar/stream-nft-client.ts`:
- Around line 76-77: Update the ownership/transferability logic in
src/stellar/stream-nft-client.ts at lines 76-77 to use an authoritative
transferability query or explicitly enforce and test the invariant that every
owned NFT can be transferred; do not rely solely on ownerOf. Update
src/stellar/router-client.ts at line 352 to derive its metadata from that same
authoritative invariant rather than independently returning true.

Record the contract release and commit for the v0.2.3 artifacts.
The provenance checklist at Lines 35-40 requires every binding release to include a contract release tag and commit. The new section records the verification command, CLI version, and WASM hashes, but omits both source identifiers. Add them so the listed artifacts remain traceable to an exact contract source.

Synchronize the error definitions with the generated bindings.
The table maps Flow code 2 to StreamAlreadyVoided. The generated Flow binding defines code 2 as Unauthorized.
The table also maps Lockup code 102 to StreamNotCancelable. The generated Lockup binding defines code 102 as Unauthorized.
These mismatches cause valid contract failures to produce incorrect names and messages. Generate this table from the contract specifications or update every entry against the current bindings.

Do not classify generic error codes as Soroban contract errors.
An HTTP error with code: 401 matches these paths and becomes Paymaster AlreadyInitialized. The same parser handles failures from every Stellar client.
Require a Soroban-specific error shape or contract-error message. Alternatively, pass the expected contract to the parser and validate its code range.

Reject Lockup NFTs before calling void_stream.
coreStreamId discards the NFT stream type. If the caller supplies a Lockup token, this code sends its core ID to the Flow contract.
When Flow and Lockup IDs overlap, the operation can void the wrong Flow stream if the caller is authorized for that stream. Load the complete NFT stream data and require GeneratedStreamType.Flow before calling void_stream.
