Tasks 4-7 on the Boss-Repaired plan, completing the M1 iteration: - Task 4: check-side export-signature gate — CheckError variants ExportNonScalarSignature / ExportHasEffects (codes export-non-scalar-signature / export-has-effects), code() arms, check_fn gate (params->ret->effects, first-violation-wins, unconditional on f.export.is_some()). The clause-3 discriminator in code: effectful/non-scalar exports fail to typecheck. 6/6. - Task 5: codegen Target::StaticLib — Target enum, threaded param, @main/MissingEntryMain gated behind Target::Executable, one external @<sym> forwarder per export to @ail_<module>_<fn> (fn_scalar_sig/llvm_scalar). In-source missing_entry_main_is_error byte-unchanged. Lowering pin 2/2. - Task 6: CLI ail build --emit=staticlib — clap field, Cmd::Build branch, build_staticlib (verbatim build_to prefix + has_export guard + two-archive clang -c/ar rcs tail) + run_cmd. CLI pin 2/2. - Task 7: C-host E2E coherent-stop proof (cc links libembed_backtest_step.a + libailang_rt.a, backtest_step(0,3)=9 / (9,4)=25, s==25, exit 0) + DESIGN.md §"Embedding ABI (M1)" (scalar C ABI, provisional until M3). E2E pin 1/1. Independent Boss verification: E2E 1/1, gate 6/6, full workspace 0 failures, roundtrip_cli + design_schema_drift + spec_drift green, Invariant 1 holds (no new dep in core/codegen/runtime). 3 behaviour- neutral plan pseudo-vs-reality concerns in the journal. Default-exe codegen/runtime path byte-unchanged (check.py firing = tracked-P2 known-noise, audit-adjudicated). INDEX line added. Completes the M1 iteration (impl). Milestone-close audit + fieldtest (surface-touching) are the next pipeline steps.

//! Embedding-ABI M1 export-signature gate (spec §3, clause-3
|
|
//! discriminator): an `(export …)` fn whose params/ret are not all
|
|
//! `Int`/`Float`, or whose effect set is non-empty, MUST fail
|
|
//! `ail check` with the new diagnostic. A scalar+pure export passes.
