Brummel 6fdb45d2f2 iter rpe.1: retire per-type print effect-ops
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.

Brummel feb941363a bugfix: print leak — propagate ret_mode through rigid substitution
`(app print x)` under --alloc=rc leaked the heap-Str allocated by
`show x` in print's body: the let-binder `s` in
`(let s (app show x) (do io/print_str s))` was never flagged
trackable, so the drop site at scope-close emitted no
`ailang_rc_dec(s)`. Minimal repro `(body (app print 42))` produced
`allocs=1 frees=0 live=1`.

Root cause is two-layer:

1. examples/prelude.ail.json declared the Show class method `show`
   without an explicit `ret_mode` on the return type, so serde
   defaulted to ParamMode::Implicit. Fix: add `"ret_mode": "own"`
   on the Show.show method, parallel to how the heap-Str-producing
   builtins (int_to_str, bool_to_str, float_to_str, str_clone,
   str_concat) declare it. examples/prelude.ail regenerated via
   `ail render` to stay parse-isomorphic with the JSON.

2. crates/ailang-check/src/lib.rs `substitute_rigids` was silently
   stripping `param_modes` and `ret_mode` whenever it rebuilt a
   `Type::Fn`, so even after the prelude fix, the mono-synthesised
   `show__Int / Bool / Str / Float` lost the `Own` annotation
   during rigid substitution. Fix: preserve both fields through
   the substitution.

RED pin: crates/ail/tests/print_no_leak_pin.rs (test
`alloc_rc_print_int_does_not_leak_show_result_str`) + fixture
examples/print_int_no_leak_pin.ail asserts allocs == frees and
live == 0 for `(body (app print 42))` under --alloc=rc.

Ten mono-body hash pins re-recorded (eq__Int/Bool/Str,
compare__Int/Bool/Str, show__Int/Bool/Str/Float, eq__IntBox) —
the bodies are semantically identical; the canonical JSON now
carries the previously-stripped mode metadata, so the body hash
moves. Re-pinning is bookkeeping for the intentional drift, not
a workaround.

Surfaced 2026-05-14 during the rpe.1 BLOCKED orchestrator run
(Cat A). Existed in latent form since iter 24.3 (when Show + print
shipped); only became user-observable when `(app print ...)` joined
the corpus. cargo test --workspace: 565 / 0 / 3.

Open follow-up flagged for next /audit: grep for `Type::Fn { ..., .. }`
field-spread sites — any other shape that drops modes during
rebuild is a latent instance of the same bug class. Out of scope
for this minimal fix.

Brummel abcdd05991 iter clippy-sweep: clear all 61 cargo clippy warnings
Hygiene sweep across the workspace under `cargo clippy --workspace
--all-targets`. Before: 61 warnings. After: zero. Tests stay 563
green, `cargo doc` stays at zero warnings, and all three bench
scripts exit 0 against existing baselines.

Twelve lint classes, three fix shapes:

- Documentation hygiene (~32 hits): `doc_lazy_continuation` resolved
  by adding blank lines before continuation paragraphs or rephrasing
  the offending line; plus four `empty_line_after_doc_comments` hits
  in workspace.rs where eight `///` blocks left orphan by form-a.1
  T5 test relocation were converted to plain `//`.
- Idiomatic refactors (~16 hits): `.err().expect()` → `.expect_err()`,
  redundant `.into_iter()` and `.into()` removed, `|f| g(f)` →
  `g`, `.trim().split_whitespace()` → `.split_whitespace()`,
  `push_str("x")` → `push('x')`, two manual `impl Default` flipped
  to `#[derive(Default)]` + `#[default]`, two nested `if let Some(_)
  = …` collapsed.
- Block extraction (1 hit): a 13-line block inside an `else if`
  condition in synth's Var-arm extracted to a new helper
  `is_class_method_dispatch(name, env)` next to
  `qualifier_is_class_shape`.

Three `#[allow]`s with inline rationale where clippy's suggestion
would lose meaning: `only_used_in_recursion` on walk_pattern (the
parameter preserves the five-fn walker-framework signature
uniformity), 2× `if_same_then_else` on qualify_local_types shapes
(two branches encode semantically distinct disqualification
reasons), `too_many_arguments` on `Emitter::new` (8 workspace-flat
tables; bundling would just rename boilerplate).

Brummel 77b28ad64d 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.

Brummel 92e830e6c2 iter 23.5: prelude free fns + E2E — Eq/Ord milestone close
Five polymorphic prelude free fns (ne/lt/le/gt/ge) plus three E2E
fixtures: positive composition over Int/Bool/Str, user-ADT with
user-written Eq/Ord on IntBox, and Float-NoInstance with a
Float-aware diagnostic addendum cross-referencing DESIGN.md §"Float
semantics".

Two checker-side fixes were needed alongside the prelude additions,
both symmetric to the iter 23.4-prep visibility fix:
- linearity::check_module_with_visible — workspace-aware callee-mode
  resolution so a Borrow-mode user fn forwarding into a prelude poly
  fn (e.g. `at_most x y = not (gt x y)`) doesn't false-fire
  consume-while-borrowed.
- mono::collect_mono_targets — distinguish rigid forall vars from
  unbound metavars; rigid-bearing free-fn targets skip (they get
  re-collected with concrete subst when the enclosing fn itself
  monomorphises). Without this, a polymorphic body calling another
  polymorphic free fn produced a spurious __Unit specialisation
  whose body referenced compare at Unit.

Roadmap split: shipped Eq/Ord half checked, Show + print-rewire half
remains pending behind the heap-Str ABI prerequisite. DESIGN.md
§"Prelude classes" amended.

One pre-existing fixture (test_22b1_missing_method) renamed its
class method ne → tne to avoid collision with the new prelude `ne`.

Bench: check.py + cross_lang.py exit 0; compile_check.py exits 1
with one sub-ms check_ms.local_rec_capture at +26% (tolerance 25%) —
prelude-growth-related noise-band fluctuation, ratifiable per spec
§248-249 and journal Concerns.
