- Introduced AGENTS.md, README.md, TASKS.md, and implementation_plan.md for Vexer, detailing mission, responsibilities, key components, and operational notes. - Established similar documentation structure for Vulnerability Explorer and Zastava modules, including their respective workflows, integrations, and observability notes. - Created risk scoring profiles documentation outlining the core workflow, factor model, governance, and deliverables. - Ensured all modules adhere to the Aggregation-Only Contract and maintain determinism and provenance in outputs.

# Entry-Point Runtime — Rust
|
|
|
|
## Signals to gather
|
|
- ELF binaries with DWARF producer strings containing `rustc`.
|
|
- Symbols prefixed with `_ZN` (mangled Rust) or section `.rustc`.
|
|
- Presence of `panic=abort` strings, `Rust` metadata, or Cargo artefacts (`Cargo.toml`, `Cargo.lock`).
|
|
- Statically linked (no `.dynamic` entries) in many cases, or musl loader (`/lib/ld-musl-x86_64.so.1`).
|
|
- Environment such as `RUST_LOG`, `RUST_BACKTRACE`.
|
|
|
|
## Implementation notes
|
|
- Parse DWARF `.debug_info` when available; short-circuit by scanning `.comment` sections for `rustc`.
|
|
- Distinguish from Go by the absence of `.note.go.buildid`.
|
|
- When Cargo artefacts exist, include target name and profile in evidence.
|
|
- For binaries built with `--target x86_64-pc-windows-gnu`, treat them under the same detector (PE + Rust markers).
|
|
|
|
## Evidence & scoring
|
|
- Reward DWARF producer strings, Cargo files, and Rust-specific env vars.
|
|
- Penalise when only generic static binary traits are present (may defer to C/C++).
|
|
- Mention musl vs glibc loader differences for observability.
|
|
|
|
## Edge cases
|
|
- Rust compiled to WebAssembly or run inside Wasmtime falls outside this detector; leave as `Other`.
|
|
- Stripped binaries without DWARF or comments may be indistinguishable from C—fall back to C/C++ and add note.
|
|
- Supervisors launching multiple Rust binaries handled upstream.
