Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to Media decoding can release handles prematurely when a union tries an incompatible variant, potentially causing invalid reads or failures in generated Rust clients. The bridge test suite has also not completed successfully, so this PR is not ready to merge until the handle-lifetime issue is addressed and the required test run completes.

Mediavariant mapping.
Media::from_bamlmaps five kinds to five variants at lines 491-497. That map is hand-written, and no test covers it. TheMediaValuedecode path needs no loaded runtime, so this test runs in the same#[cfg(test)]module as the existing tests.♻️ Suggested added test

Line 64 panics when
capi::api()fails. Line 84 panics when the engine returns a non-zero status.__BamlValuePrivate::to_bamlreturnswire::InboundValue, so it cannot propagate an error, and a panic is the only available signal here.The risk depends on emit order in the generated bindings. If a generated function encodes its arguments before it calls

HandleGuardcallshandle_releaseon every path after line 187. This is correct only if the engine transfers ownership of the handle key in an outbound value to the host. If the engine retains ownership, this release is a double free.The engine side is not part of this cohort, so the contract cannot be confirmed from the supplied files. Confirm how other outbound handle consumers in this crate treat handle ownership, and confirm the engine-side release contract.

375-383: 🎯 Functional Correctness
⚠️ Unverified finding
Sandbox verification was unavailable.Confirm whether a generic media wrapper class exists.
from_wrapper_classmaps four wrapper class names. It has no arm for generic media, so a generic media value that arrives as aClassValuedecodes toDecodeError::WrongType { got: "class" }.
Kind::Genericis otherwise a full kind: it maps toMediaTypeEnum::Other,BamlTyMediaKind::Generic, andBamlHandleType::AdtMediaGeneric. Generic media therefore decodes through theMediaValueand handle paths but not the class path. Confirm the engine wrapper class names, and add the generic arm if such a class exists.

Option<String>frombase64.
urlandfilereturnResult<Option<String>, SdkError>.base64collapses the absent case into an empty string, so a caller cannot distinguish "not base64-backed" from "empty payload". The public wrapper documents this behavior, so it is intentional. If the surface is not yet stable, aligning the three accessors is cheaper now than after release.🤖 Prompt for AI Agents

185-190: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winPreserve the constructor failure detail.
createreturns anSdkErrorthat names the constructor and the ABI status, for examplemedia.from_url: internal error (status 4). Themap_errdiscards it and reports onlymedia descriptor rejected by the runtime. A runtime rejection is then hard to diagnose from the error alone.Consider carrying the cause, for example by extending
DecodeError::InvalidMediawith an owned detail string, or by adding a dedicated variant.🤖 Prompt for AI Agents
