First half of spec iteration mir.1 (docs/specs/0060-typed-mir.md, plan docs/plans/0114-mir.1a-mir-infrastructure.md). Purely additive: a new leaf crate plus a post-mono lowering walk plus the front-end entry. Nothing consumes MIR yet — codegen and the CLI are untouched — so the whole existing suite stays green (102 test-result-ok lines, 0 failed; the one ignored is the #49 pin, which lifts at mir.4). mir.1b flips codegen to consume MIR and deletes the synth_with_extras mirror. What lands: - `ailang-mir` (new leaf crate, depends only on ailang-core): MTerm / MArg / MArm / MLoopBinder / MNewArg / Callee / Mode / StrRep / MirDef / MirModule / MirWorkspace, structurally complete over all 17 Term variants plus the dedicated Str split (MTerm::Str{lit,rep}). Every later-iteration annotation field exists now at a mir.1 default (App.callee = Indirect, MArg.mode/consume_count = Owned/1, Str.rep = Static, New.elem = None); the struct shape will not change across mir.2–mir.5, only the values. MTerm::ty() reads the carried type. - `ailang-check::lower_to_mir`: the post-mono walk. Carries no second type engine — it calls the canonical `synth` per node with fresh throwaway inference scaffolding (subst/counter/residuals/…), applies the substitution, and threads only the lexical locals/loop_stack, maintained by the same push/pop rules synth uses (Let, Loop, Lam, LetRec, and Match via synth's own type_check_pattern). This is the "one engine, not two" property the milestone buys, on the producer side. - `ailang-check::elaborate_workspace`: the single front-end entry — check (diagnostics gate) → desugar+lift → monomorphise → lower_to_mir — transcribed from the CLI build path. check_workspace stays for the diagnostics-only callers. - Three ty-fill pins (crates/ailang-check/tests/lower_to_mir_ty.rs) load the #51/#53/#49 witnesses as fixtures and elaborate the whole workspace, so lower_to_mir is exercised over the full prelude+kernel, not just the tiny witness. Two new witness fixtures (examples/new_{rawbuf_size_only,counter_user_adt}.ail); #49 reuses the existing loop_recur_str_binder_no_leak_pin.ail. Deviations from the plan, all forced by ground truth and verified against the live code before commit: - FnDef.export is Option<String>, not bool — dropped from MirDef (the plan's note allowed this fallback). Codegen reads FnDef.export directly, unaffected. - fn_param_types did not exist — lifted the param-type extraction into a shared pub(crate) fn and rewired both mono.rs sites (collect_mono_targets, collect_rewrite_targets) to it, so the param-type source cannot drift between mono and lower_to_mir. The helper unwraps a top-level Forall then reads Type::Fn.params — identical to the inner_ty extraction it replaces; the early-return non-fn guard is preserved at both sites. Behaviour-preserving (whole suite green; this is the only edit to existing mono behaviour). - lower_module mirrors two more mono.rs scaffolding rules the plan under-transcribed: skip intrinsic-bodied fns (they are signature-only; lowering them would hit synth's Term::Intrinsic guard) and seed env.current_module + env.globals + env.imports per module so synth's Var lookup resolves post-mono specialisations (e.g. compare__Int) in the prelude. - The #53 pin asserts the lowered (new Counter 42) init carries ty Counter, not that it is an MTerm::New: a monomorphic `new` over a user ADT is desugared to a dotted call `(app Counter.new 42)` before lower_to_mir runs (desugar.rs:1078-1098), so it lowers to MTerm::App. MTerm::New survives only for a polymorphic `new` carrying a written NewArg::Type (the #51 RawBuf path, covered by the rawbuf pin). The pin's intent — ty-fill correctness — is preserved; the structural variant is mir.2/mir.5 territory. - ailang-mir uses workspace-inherited Cargo fields for consistency with the existing crates (added it to [workspace.dependencies]). refs #49
