test_shell_lone_copy_reds_on_its_sibling asserted the fixture path it had just
built while verify_hermes_setup.sh reports the path it resolved with readlink -f.
Under TMPDIR=/root/.hermes/profiles/volt/cache/scratch_link a correct pair read
MISSING and the gate went rc 1 (measured before the repair: that cell was the
only red, 15 others ok). The fixture root is now canonicalised once in setUp
with os.path.realpath; two new cells pin the alias reading instead of assuming
it -- a lone copy reached by a directory symlink names the real sibling that is
absent (rc 1), and the same alias with the sibling present reads PASS (rc 0).
CHECK-env-verifiers now runs the suite twice, ambient TMPDIR and a directory
alias it builds, so the shape that produced the flake is graded every run.
16 cells; negative control (raw mkdtemp restored in a scratch copy) reds the
alias leg and only that leg, rc 1.
snippet.py: check_tools() imports hermes_tools and requires callable(getattr(...));
--require is the negative-control hook; HERMES_HOME/HERMES_PROFILE/--home/--profile
resolve every path; rc 0/1/2. verify_hermes_setup.sh: HERE from $0, sibling
snippet.py graded, --home/--root/--profile, VERDICT line, rc 0/1/2.
New test_env_verifiers.py (14 black-box cells, stub hermes_tools on PYTHONPATH,
synthetic trees) and CHECK-env-verifiers. Pre-repair blobs: 9 cells red for
snippet.py, 6 for the shell script.
The old check imported json, subprocess and datetime -- all stdlib -- so
its failure condition was unreachable, and its version-reporting helper
check_package was defined and never called. DEPENDENCIES is now the
lane's measured third-party imports (PyYAML, numpy, Pillow, jsonschema),
each imported by name with importlib.metadata version; missing -> rc 1,
broken -> rc 1, usage error -> rc 2. email_validator is not declared:
spark's own email_validator.py is a local stdlib-only module.
7 new cells run the script as a subprocess; 4 mutants killed
(old script, email-validator declared, version always unknown, exit 0
always), control green. Queue Q120 closed with the record appended and
docs/queue-index.md re-rendered in the same commit.
