Single iter shipping the post-milestone-24 follow-up named in
docs/specs/2026-05-14-retire-per-type-print-effects.md. After this
iter the only surviving direct-output effect-op is `io/print_str`;
all per-type print primitives are replaced by the polymorphic
`print` helper (prelude, iter 24.3).
Components:
- 92 examples/*.ail fixtures migrated (do io/print_<T> x) →
(app print x); 6 .prose.txt snapshots regenerated via `ail prose`.
- Four-site lockstep compiler deletion: crates/ailang-check/src/builtins.rs
(3 effect_ops.insert blocks + 3 list() rows + the
install_io_print_float_signature test + module + EffectOpSig
doc-comments); crates/ailang-codegen/src/lib.rs lower_app
(3 arms + lowers_io_print_float test); crates/ailang-codegen/src/synth.rs
builtin_effect_op_ret match-arm pattern. Dead `intern_string`
helper removed as a follow-up.
- Five incidental test-body migrations (ailang-check x2, ailang-core
spec_drift + design_schema_drift, ailang-surface/src/lex.rs,
ailang-prose/src/lib.rs round-trip test).
- Cat B test-harness patch: six IR-shape tests in
crates/ail/tests/e2e.rs gained a monomorphise_workspace call
before lower_workspace_with_alloc so they follow the same
pipeline as `ail build` (the home-rolled desugar+lift loop
stayed because mono's precondition is "already lifted"; mono
inserts after lift).
- Six doc-comment touch-ups (lex.rs module doc, parse.rs
diagnostic example, ail/src/main.rs x2, runtime/str.c %g anchor,
crates/ailang-core/specs/form_a.md surface-spec example).
- DESIGN.md seven-site sweep (Decision 11 example, Polymorphic
print past-tense, Heap-Str output sentence, effect-op
invocation comment, Float NaN paragraph re-anchored on
float_to_str, two "What is supported" lists).
- Three E2E test-comment polish + four IR-snapshot refresh + one
canonical-hash pin update (plan-unanticipated downstream
consequences of the corpus migration).
- bench/{check,compile_check,cross_lang}.py: all exit 0; no
ratification needed.
- Roadmap entry struck through; per-iter journal at
docs/journals/2026-05-14-iter-rpe.1.md.
Tests 564/0/3. cargo clippy and cargo doc: zero warnings.
Two upstream codegen bugs surfaced during the first BLOCKED
attempt and were fixed in separate iters before this retry:
- 1fb225e bugfix: mono cursor misalignment at poly-free-fn Var
with class-constrained Forall.
- feb9413 bugfix: print leak — propagate ret_mode through rigid
substitution + prelude Show.show ret_mode.
Known debt (carried forward for next /audit):
- Emitter.strings field is functionally dead post-iter (orphan
after intern_string removal); cycles over empty map harmlessly.

//! Floats milestone iter 4.6 — end-to-end fixture.

//!
|

//! `examples/floats.ail.json` is built via the public `ail build`
|
|
//! CLI and run; stdout is matched against the expected three

//! lines (`4`, `42`, `-1.5`). This test exercises the full

|
|
//! `int_to_float` (sitofp), `neg` Float (fneg), and the polymorphic

//! `print` for Float (routes through `Show Float.show` →
