Every surviving carrier now owns its artifacts: checked mkdir/mkdtemp/ fopen acquisition, one all-exit cleanup funnel per carrier, ENOENT- tolerant checked unlinks, exact-path deletion (rm -rf only for an owned pid-keyed dir or a .sepwork beneath one), and cleanup failure fails a passing carrier without overwriting its diagnostic. In the same pass the carriers adapt to the driver contract this branch lands: --sep and WW_PKGCACHE are gone, -S and the /tmp/ww_run_<pid> scratch contract are asserted, and rows whose runtime or reject coverage moved to test/wcc/data fixtures or test/lang @test owners are trimmed to the byte/artifact/diagnostic observations only they can make. Repair and adaptation ride together because most files interleave both in the same hunks; splitting would manufacture intermediate carrier states that never existed and cannot run against either driver.

* 911_attest_record — #17 record-and-continue harness (lib/test + the
|
|
* table-synth -T entry). Sibling of 989_septest_run + 911_attest_drop
|
|
* (which pin the synth entry 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 clamp any failure set to exit 1.
|
|
* 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/...).
