ww test: fork-isolated record-and-continue harness (lib/test, both stages)

Browse Source 
lib/test/run.ww: fork+wait4 runner; each @test runs in its own child,
abort/SEGV/FPE decoded from wait-status, failures recorded and the run
continues; exit = fail count. Tests are hermetic: module globals do not
persist test-to-test (fresh fork image; sanctioned divergence from
harec's shared-process __test_main, no setjmp/signal layer needed).
-T synth (both stages) emits a module-global (str,*fn() void) table +
return run(table) instead of straight-line calls. Driver twins bundle
lib/test under test mode and gain ww test -c/-o (go test -c) so the
byte-id gates diff the same artifact the real path builds. Gates
989/910/997 rewired onto it; new 911 pins record-and-continue across
all three fault classes; 949 +3 rows. (#17-team commit-2)

// (drew-17-attest-spec.md §a; rob ruling 2026-06-10, task #17): Hare
// isolates each test in ONE process via arch::setjmp + an rt::onabort
// hook + a SIGSEGV signal handler; ww has none of those primitives, so
// we fork per test and read the child's wait-status. A clean child
// exit(0) is a pass; abort/div0/SIGSEGV/nonzero-exit all surface as a
// failing child status, so the fork boundary catches EVERY fault class
// the setjmp+signal path catches, at a process boundary. The proven
// fork+wait4+WEXITSTATUS decode is procrun (selfhost/cmd/ww/main.ww:
// 154-177). CONSEQUENCE (sanctioned): module globals do NOT persist
// test-to-test — each test runs in a fresh fork snapshot. Hare's tests
// share one process, so its globals persist; ww's are hermetic.
//
// D1/D4/D5 reductions also retained from the -T synth era: no
// __test_array linker section (the synth hands us a value table), no
// sort, no file:line reflection. fnmatch name-filtering is task #17
// commit-3 (drew spec §d), not here.
import os;
// run — execute each test in `tests` in a forked subprocess, report a
// per-test status line, and return the failure count (the synthesized
// `export fn main()` returns this, so the process exits nonzero iff any
// test failed). The table is `[](str, *fn() void)` — Hare models a test
// as `struct { name: str, func: *fn() void }` (+test.ha:23-26); the -T
// synth emits the value-table tuple form (rob ruling), so the runner
// reads `.0`/`.1` off each row rather than named fields.
//
// The private helpers carry a `tst` prefix: until real packages (#8) give
// lib/test symbol isolation, every -T build flat-bundles this module into
// the SAME bare-leaf scope as the test's own modules, so an un-prefixed
// `puts`/`runone` collides with a same-named module-private fn (lib/dirs
// and lib/temp both ship a private `puts(off, s)`). `run` stays the bound
// runner name (the synth's callee). A user `fn run` (or `const __wwtests`)
// in a @test unit collides with the synth: cstage — the shipping `ww test`
// path — rejects it loudly ("duplicate fn run" / type mismatch, rc!=0).

* 911_attest_record — #17 record-and-continue harness (lib/test + the
* table-synth -T entry). Sibling of 910_at_test (which pins the synth
* itself + the #6 non-T drop); this one pins the RUNTIME behaviour the
* fork+wait4 runner adds:
*
* 1. RECORD-AND-CONTINUE — `ww test` the mixed fixture (one pass, then
* assert-fail/SIGSEGV/SIGFPE, then a final pass). The runner must
* proceed past every failure, emit the right per-test `name ... ok/
* FAIL` line (table-driven below), print the right `P passed, F
* failed` summary, and exit with the failure count (nonzero).
* 2. ALL-PASS — `ww test` the all-pass fixture exits 0 (no false
* failure from the new runner).
* 3. BYTE-ID (rule 10) — `ww test -c` the mixed fixture into a
* lib/test-inclusive combined, then `w6c -T` and `w6c_ww -T` must
* emit byte-identical asm (the table + fork loop, both stages).
*
* The fork changes failure OUTPUT, not pass behaviour: a passing fixture
* still exits 0, so the 35 converted lib tests stay green (904/967/...).
