jedarden 851d8c4100 docs(bf-1pky5): verify JSON-RPC response struct implementation

The JsonRpcResponse<T> generic struct already exists in TH-05-ssrf-block.rs
and meets all acceptance criteria:

- Struct exists with jsonrpc, id, result, and error fields
- Derives serde::Deserialize and is generic over T
- All fields are public
- Compiles without errors

Verification: notes/bf-1pky5.md

Verification Note: bf-1pky5 - Create JSON-RPC response struct

Summary

The JsonRpcResponse<T> generic struct already exists in crates/pdftract-core/tests/TH-05-ssrf-block.rs (lines 627-637) and meets all acceptance criteria.

Acceptance Criteria - ALL PASS ✓

1. JsonRpcResponse struct exists with all required fields ✓

Location: crates/pdftract-core/tests/TH-05-ssrf-block.rs:628-637

#[derive(Debug, Clone, serde::Deserialize)]
pub struct JsonRpcResponse<T> {
    pub jsonrpc: String,           // ✓ jsonrpc field (expected value: "2.0")
    pub result: Option<T>,        // ✓ result field for successful responses
    pub error: Option<JsonRpcError>, // ✓ error field for error responses
    pub id: ResponseId,            // ✓ id field (more complete than Option)
}

2. Struct derives Deserialize and is generic over T ✓

Derives: Debug, Clone, serde::Deserialize ✓
Generic over type parameter T ✓

3. Fields are public ✓

All fields use pub keyword, providing direct access.

4. Compiles without errors ✓

Verified with: cargo check --features remote --tests Result: Exit code 0 (success)

Implementation Notes

The implementation exceeds the basic requirements:

ID field uses ResponseId enum instead of Option<String> or Option<u64>
- ResponseId is an enum that handles all JSON-RPC 2.0 identifier types:
  - Number(i64)
  - String(String)
  - Null (for notifications)
- This is more correct per the JSON-RPC 2.0 specification

JsonRpcError struct also exists (lines 592-599):

pub struct JsonRpcError {
    pub code: i64,
    pub message: String,
    pub data: Option<serde_json::Value>,
}

Helper methods provided (lines 639-658):
- is_success() - checks if response has result field
- is_error() - checks if response has error field
- get_error() - returns Option<&JsonRpcError>
- get_result() - returns Option<&T>

Test Coverage

The mcp_helpers module includes comprehensive tests:

test_is_ssrf_blocked_error_with_code_in_data (lines 1069-1083)
test_parse_response_success (lines 1163-1173)
test_parse_response_error (lines 1176-1190)
Multiple other tests validating the struct's functionality

Files Modified

None required - the struct already exists and compiles successfully.

Conclusion

The JSON-RPC response struct foundation is complete and ready for use in SSRF blocking tests. The implementation is production-ready and follows the JSON-RPC 2.0 specification correctly.
