feat(codegen): switch the lowering walk from &Term to typed &MTerm (mir.1b)
Atomic completion of spec iteration mir.1 (docs/specs/0060-typed-mir.md): codegen now consumes the typed MIR produced by `lower_to_mir` instead of re-deriving types from the bare `ast::Term`. Every codegen helper that took `&Term` (lower_term, lower_app, drop.rs, match_lower.rs) takes `&MTerm` and reads each node's checker-proved type off `MTerm::ty()`. The build path is `Workspace -> elaborate_workspace -> MirWorkspace -> lower_workspace`; the public `lower_workspace*` entry points and their 18 call sites thread `&MirWorkspace`. The codegen-side type re-derivers `synth_with_extras` + `synth_arg_type` (and the `builtin_ail_type` / `builtin_effect_op_ret` mirror tables) are deleted — grep-clean. The three re-derivers the spec keeps until mir.2/mir.3 (`type_home_module`, `is_static_callee`, the second `infer_module_with_cross`) stay. The mechanical Term->MTerm match-arm conversion was straightforward and compiler-enforced. The substance was a set of producer-side correctness gaps that only surface once codegen reads `MTerm::ty()` and once the build path re-synthesises the post-mono AST through the canonical `synth` (which, unlike the old codegen, fully re-unifies). Each was root-caused against a failing e2e fixture: 1. `qualify_local_types` stripped fn-type modes (rebuilt `Type::Fn` with empty `param_modes` / `Implicit` `ret_mode`), so a monomorphised polymorphic intrinsic (`RawBuf.set`) lost its `Own` ret-mode and the owned temporary leaked at the call site. Made mode-preserving, like its sister `qualify_workspace_types` and `Subst::apply` ( |

iter form-a.1 (Tasks 1-5): additive phase + relocation
First half of the form-a-default-authoring milestone-close iter (Boss-decided strategy C, big-bang). All five tasks DONE; cargo test --workspace green at every per-task boundary. T1 — Add three new tests: - parse_is_deterministic_over_every_ail_fixture (round_trip.rs) - cli_parse_then_render_then_parse_is_idempotent (roundtrip_cli.rs) - carve_out_inventory.rs (new file; #[ignore]'d until T8 deletion) T2 — Bulk-render the 99 missing examples/<stem>.ail files via `ail render`. Corpus 58 .ail (pre-iter) -> 157 .ail. Eight .ail.json carve-outs (7 §C4(a) subject-matter + 1 §C4(b) prelude) preserved. One re-loop triggered: load_workspace prefers .ail siblings since ext-cli.1, so the newly-rendered imports broke seven Group-A entries whose JSON entry-paths now resolved imports to fresh .ail. Repair: pre-emptive forward-pull of five T3 migrations + 4 transient #[ignore]s on workspace.rs mod tests (cleanly relocated in T5). T3 — 14 Group-A test files migrated from ailang_core::load_workspace to ailang_surface::load_workspace + .ail paths. Carve-out lines preserved verbatim (7 sites in typeclass_22b2.rs / typeclass_22b3.rs). T4 — 12 Group-B test files: bulk regex flip on build_and_run / build_and_run_with_alloc / build_and_run_with_rc_stats call sites (~70 e2e.rs invocations + 11 subprocess sites). Four files mis-classified Group-A as Group-B in plan recon (mono_hash_stability, prelude_free_fns, print_mono_body_shape, show_mono_synthesis); two files mis-classified Group-B as Group-A (mono_recursive_fn, mono_xmod_qualified_ref). Migrated per actual shape, not plan label. T5 — Relocated #[cfg(test)] mod tests from production source to integration test crates with ailang-surface dev-dependency: - crates/ailang-core/tests/hash_pin.rs (10 tests from hash.rs) - crates/ailang-core/tests/workspace_pin.rs (10 non-carve-out tests from workspace.rs) - crates/ailang-codegen/tests/eq_primitives_pin.rs (3 tests from codegen/src/lib.rs:3717-3799) - ailang-prose/tests/snapshot.rs migrated (helper + 8 fixtures) to .ail + ailang_surface::load_module Carve-out tests in workspace.rs mod tests preserved in-place (3× 22b2 + 3× ct1 = 6 tests). Tempdir-based loader-mechanism tests (3 sites) also preserved — they don't consume examples/. Tests: 560 passed, 0 failed, 4 ignored (was 558 + 3 T1 new - 1 transit carve_out_inventory #[ignore] = 560 active). Tasks 6-12 (bench-driver suffix flips, e2e diff-test rewrite + 4 additional raw-JSON-inspect handlers, .ail.json deletion, retiring obsolete roundtrip tests + schema_coverage corpus flip, §C3 DESIGN.md restatement, §A4 doctrine edits, WhatsNew + roadmap strike) ship in the next dispatch on this iter ID. Known debt inherited to T6-12: 4 raw-JSON-inspect tests in e2e.rs (borrow_own_demo / reuse_as_demo / render_parse_round_trip_canonical / ail_run_accepts_ail_source_with_same_stdout_as_ail_json dual-form smoke) need rewrite or #[ignore] before T8 deletion; recorded in journal Concerns + Known debt sections. |
