Captain Bob, 2026-11-13: "Create the issues then fix them before the long
acceptance test runs"; #16: "Nightly".
#190 -- make -C v4 post79 did not reproduce POST:
- mkpost.py runs v3 with address randomisation off (setarch -R): its
printed addresses (>IN, FIND) are the same each run, so POST79.md is.
- v4/Makefile post79 builds hosted v3 from this tree's source first and
uses it, not the lfs/ copy, which can be older.
- post_cases.c and POST79.md regenerated: 539 cases -- LOAD.rest_of_line,
which v3 gets through since it changed after 2026-10-07. Two runs the
same. POST_FLOOR 538 -> 539 (#173).
- test_host_unit.c takes the table's count, not 538 typed in the test.
#16 -- scripts/nightly.sh v4-checks: make -C v4 sanitize hosted-check,
logged under logs/<TS>/v4-checks/, refused without qemu-user; nightly.yml
runs it after publishing, before the proofs, installing qemu-user if the
image lacks it.
Evidence (logs/20261113-014927/post79, -024314): before, regenerated with
nothing changed: 539 cases and addresses differing run to run; after: the
same twice, hosted POST 539/539; test, test-32 99 programs 0 failures;
v4-checks 79 programs under the sanitizers 0 failures, the hosted builds
alike. The first verification failed at test_host_unit.c:442 (kept); a
stray v4-checks run stopped at once is kept, labelled (-014453).
