check: mode-strict-because suppression (iter 19b)
...
Closes the 19a/19a.1/19b arc. Corpus signal from 19a.1 (5/65
fixtures fire over-strict-mode, all deliberate RC codegen-test
fixtures) justified shipping the suppress mechanism end-to-end.
Schema: Suppress { code, because } on FnDef. Pre-19b hashes
bit-identical via skip_serializing_if. Typechecker drops matching
diagnostics; empty 'because' is Error severity; wrong codes are
silent no-ops (open-set registry).
Form-A: (suppress (code "...") (because "...")) clause, parser
+ printer round-trip clean. Form-B: '// @suppress <code>: <reason>'
above the doc string, lossless contract metadata.
5 RC fixtures migrated (.ail.json + .ailx + .prose.txt). Corpus
signal: 5/65 -> 0/65. Lint still fires on any future fn that's
accidentally over-strict without an authored reason.
Test counts: ailang-check 55->61, ailang-core 26->28, ailang-surface
21->26, ailang-prose 49->52, e2e 70 unchanged.
Known debt: .ailx comment headers lost on regen (ail render's
contract excludes comments); parse_suppress_attr accepts
duplicate code/because attrs without diagnose (bounded by canonical
print order).

prose: infix + paren elision + doc-wrap + nested-match (iter 20b)
...
Eleven binary builtins (+ - * / % == != < <= > >=) render as
lhs op rhs when called with two args (tail-flagged keeps prefix).
Standard Rust-aligned 4-level precedence table elides parens.
not(x) renders as !x. Long /// doc strings wrap at 80 cols on
word boundaries.
bench_list_sum: 'if ==(n, 0)' becomes 'if n == 0', '+(acc, h)'
becomes 'acc + h', tail keyword still visible on tail calls.
19 new unit tests (47 total). 4 snapshots (3 re-rendered + 1 new
bench fixture). Public API unchanged.

prose: human-readable projection renderer (iter 20a)
...
New crate ailang-prose with one public fn module_to_prose(&Module)
-> String. Rust-flavour with braces, =>-match-arms, mode keywords
(own/borrow), effects as trailing 'with IO', Cons(1, Nil) ctor
form, /// doc strings.
Lossy projection where the LLM can re-derive: (con T) wrap,
(fn-type ...) wrap, (term-ctor ...) wrap. Load-bearing semantic
detail stays visible (modes, effects, clone, reuse-as, doc strings,
type annotations, tail flag).
CLI: 'ail prose <file.ail.json>' prints the projection.
3 snapshot fixtures + 28 unit tests. 215-line .ail.json reduces
to ~18 lines of legible source.
20b queued: infix arithmetic, paren elision, let-inlining, do
prettify.
