Oracle re-review on PR #26 flagged that the Swift-side `_ = unsafeBitCast(fn as @convention(c) ...)` static references in ChanoraSileroSelfTest.run() are not a robust anti-dead-strip guarantee under WMO + LTO. The optimizer can prove the discarded result has no side effects and eliminate the address-taken reference. The load-bearing fix is a second linker flag per symbol: -u _sym forces the symbol as undefined at link time, preventing the object that defines it from being dropped and stopping -dead_strip from removing the definition. -exported_symbol _sym was already present; re-exports the symbol in the binary's dynamic symbol table so the Rust framework's dlsym(RTLD_DEFAULT) can find it. This flag alone does NOT prevent dead- strip; it only controls the export list applied AFTER dead-strip. Both flags now appear per symbol on both iOS and macOS Release xcconfigs. The Swift-side static references stay as defense-in-depth but are no longer the load-bearing guarantee.
