调研方向
Read aimdb-core/src/typed_record.rs around line 1524 to understand the rejected value error, then trace how map_db_err in aimdb-core/src/session/aimx/dispatch.rs maps it and how RpcError is decoded in aimdb-client/src/engine.rs and aimx/codec.rs. The issue calls for a distinct wire error code that preserves the deserialization message while keeping engine and transport failures internal. Done means rejected values produce the specific error and unknown codes still fall back as described; the issue does not name tests to run.

描述
Describe the bug
When a remote record.set value fails to deserialize into the record's type, the client gets the same error as a broken engine or transport:
AimDB client error: Server error (code internal): engine/transport failure
The write is refused correctly and the session stays up. The problem is the report: a caller, especially an MCP agent, cannot tell that its own value was at fault, so it has no reason to correct it.
The server does build a specific message (typed_record.rs:1524), but it is lost on the way out:
map_db_errsends everything except not-found and permission errors toRpcError::Internal.RpcErrorcarries no message, so the client fills in its generic text (engine.rs:593).
To Reproduce
- Run an instance with a writable record whose type rejects some JSON, for example a custom deserializer that bounds a list's length.
- Call
record.set(or MCPset_record) with a value that type rejects. - See the error above.
Observed with a list over its bound (33 and 2000 elements against a limit of 32). A coordinate of 1e40 for an f32 field got the same reply; I did not trace that case separately.
Expected behavior
A distinct error code for a value the record's type rejected, separate from internal, ideally carrying the deserialization message. Real engine and transport failures keep internal.
Environment
- OS: macOS 13 (Darwin 22.6)
- Rust Version: rustc 1.98.0
- AimDB Version: main at d9c7be0
Additional context
A new code changes the AimX wire vocabulary, so existing clients need to handle it. code_err in aimx/codec.rs currently maps unknown codes to Internal, so older clients would fall back to today's behaviour.
