Track guessed as N from the FAILING STEP — line 2 of 12, /tmp/test_nilpy_modmemval26 | diff -u test/test_nilpy_module_member_as_a_value.expected -, which names test/test_nilpy_module_member_as_a_value.expected. Not from the job's name or its src: those describe what the job is ABOUT, and this job's recipe spans 2 source file(s). The ranker reads frontmatter, so this line — not the body — decides who works it; correct it if the guess is wrong.

origin/master has advanced 1 commit(s) since this sha. Re-verify at current HEAD before acting — the callback is tagged to the sha that was tested, which may no longer be the state of the tree.

• 2026-09-16 — auto-closed by the borg watcher: test-core#src:test/test_nilpy_module_member_as_a_value.npy passes at e572bd42501e (tier native); it was red at 5dbee723e228. Reopening is by a fresh NEW-RED stub, since a second red is a second finding with its own range.
