@test was parsed then dropped (no consumer); `ww test` needed a hand-written
main listing each test by hand, so adding a @test and forgetting the call
silently skipped it. -T makes the checker collect @test N_FNDECLs in source
order, loud-reject a user main, and append a synthetic
`export fn main() i32 { t0(); ...; return 0; }` at the install->body-check seam;
the existing cgfn emits it (cgen untouched) -> byte-identical by construction.
Mirrors harec's checker-side is_test placement.
Plan-9-lean reduction (user-sanctioned, reinstatable post-CSP): sequential,
abort/nonzero=fail; no setjmp isolation, no fnmatch filter, no file:line.
910/997 rewired from a regex scanner to driving `w6c -T` directly (thin trusted
drivers; the @test content stays ww), with a cross-stage byte-id assert on the
-T output. attest_userman/attest_badsig pin the user-main and bad-signature
rejects.

// #15 negative fixture: an @test fn with a non-`fn() void` signature.
|
|
// The collector must loud-reject (nonzero exit) rather than silently
|
|
// skip or coerce — rule-7. Pins the signature guard on both stages.
|
|
//
|
|
// TEETH: a non-void RETURN with NO params is the case ONLY the explicit
|
|
// guard catches. The synth entry emits `bad();` (arg count matches 0
|
|
// params) and a discarded non-void return is silently allowed, so
|
|
// without the guard this compiles clean (exit 0). A param-bearing @test
|
|
// would instead trip the checker's independent "not enough arguments"
|
|
// (check.c:1879) on the synth `bad()` call — so a param fixture would
|
|
// pass the reject probe whether or not the guard exists, isolating
|
|
// nothing. Hence the no-param / non-void-return shape.
