- IrModule.core lands the resolved export map + mode-provided symbol names on the IR; both emitters generate the external ccc wrappers, the re-runnable init entry (globals released and zeroed, error-vt stamps, %main, escaped-exception check), sink registration, and the optional reset/collect entries from the same facts
- marshalling wrappers delegate to scr_core.c helpers (str/bytes in-copy, arena-out), so the two emissions are identical by construction; both arena postures emit from resultResetSymbol
- compileCoreArchive builds <name>.core.a: program TU + the narrowed core runtime set (no scr_async/scr_child) + IR-gated pure-data units, all -DSCR_CORE; vendored zlib objects keep the libc/libm-only undefined-reference contract on hosts
- profile-mapped exports seed lowering reachability (coreRoots) so uncalled exports stop dead-stripping on the core path
- emitted family-4 traps (OOM, invalid union tag, bad key) route through scr_trap in both backends
- CLI verb: scriptc core --profile <file> [-o out]
- A type-error stop prints the same code frames a build prints
- The import-site stop renders its diagnostics below the blocker table
- Coverage is the first command reached for; the verdict line alone swallowed the fix
