Goal

The pro-grade standalone Rust analyzer (layer 2): consume the remark stream and deliver the LLVM opt-tooling analogs that turn dump-reading into a ranked worklist.

Implementation Sketch

• New standalone Rust analyzer crate; JSONL ingest of the remark stream.
• opt-stats analog: cause-cluster ranking — surviving RC ops grouped + ranked by lattice dimension (the aims-burden proof-failure worklist).
• opt-diff analog: two-build remark comparison keyed on (pass, name, function, debug_loc, ssa_value).
• opt-viewer analog: source-annotated survivor view (function-level when span is None).

Spec References

• LLVM opt-viewer.py / opt-stats.py / opt-diff.py prior art (https://llvm.org/docs/Remarks.html).

Work Items
