CLAUDE.md@public/files/bun/scripts/verify-baseline-static claudeA
CLAUDE.md@public/files/bun/scripts/verify-baseline-static is agent-read markdown (claude) from modem-dev/ossrules.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# verify-baseline-static — triage guide Static ISA scanner. Disassembles every instruction in `.text` of a baseline Bun binary and flags anything the baseline CPU can't decode. Catches `-march` leaks at compile time, before they SIGILL on a user's machine. This file is for triaging CI failures. For architecture details see `README.md` and inline comments in `src/main.rs` / `src/aarch64.rs`. ## This is a best-effort check, not a proof A PASS here does **not** guarantee the binary is baseline-safe, and a FAIL does not guarantee a real bug. Treat it as a sensitive smoke detector, not an oracle. The emulator phase (`scripts/verify-baseline.ts`) is the complementary check — together they catch most things; neither alone is bulletproof. **Out of scope entirely (tool will never find these):** - **JIT-emitted code.** JSC compiles JS/WASM to machine code at runtime; none of it exists in `.text` at scan time. If the JIT backend emits post- baseline instructions on a baseline CPU, this tool is blind to it. The emulator's `--jit-stress` path covers this. - **Dynamically loaded code.** N-API addons, FFI callees, dlopen'd shared libs. Scanner only reads the `bun-profile` binary. …

How to install
mdr add modem-dev/ossrules/public/files/bun/scripts/verify-baseline-static/CLAUDE.md@git:20260915.977fcedmdr add modem-dev/ossrules/public/files/bun/scripts/verify-baseline-static/CLAUDE.md@sha256:7bcf854691cdd840Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
