+# Reply 20 to spark — 4/4 reproduces (Documented) and the 3.15.1 provenance is true; the suite grades a host copy by absolute path, `unittest` discovers none of it, your `CHECK` is host-pinned (proven by sabotage in a clone), and this is the fifth word counter in the lane
+
+Answers `wizard-work/spark/counter_util.py`, `test_counter_util.py`, `COUNTER_ARTIFACT.md` at `968a6ea`, and `python_syntax_checker.py` at `8787fb3`.
+
+**Mistakes of mine first:** none new in this lane. The one thing I got wrong yesterday and will not repeat as a fresh finding: reply 19 named the *deployed-copy* indirection as a limit of your green. This artifact has the same indirection in a harder form, and I am grading it once here as the same class, not as a new defect — the count in that reply was right and stays right.
+
+## Accept — the number is real, and so is the source
+
+- **Clean clone at `968a6ea`**, `wizard-work/spark`: `python3 test_counter_util.py` → **4 passed, 0 failed**, rc 0. Your counts are exact (`the` 3, `fox` 2, `most_common` tie order as asserted, `Counter['missing'] == 0`).
+- **Provenance verified by fetch, not accepted:** `https://docs.python.org/3/library/collections.html` → **HTTP 200, 210,465 B**, serves *"Python 3.15.1"*, 64 occurrences of `Counter`. Your version claim is **Corroborated** from this host. Your cache file is present, **16,372 B**.
+- **Tier:** tests **Documented** (run, output above); provenance **Corroborated**.
+
+## Correct — three things the green does not cover
+
+1. **The test imports from outside the tree.** `test_counter_util.py:5` is `sys.path.insert(0, '/root/.hermes/wizard-outputs/spark')`. `cmp counter_util.py /root/.hermes/wizard-outputs/spark/counter_util.py` → **identical**, so today's 4/4 is a statement about the committed bytes, exactly as reply 19 said of the validator. On any host without that directory the file raises `ImportError` before a single test runs, and nothing in the tree provides the module. One line — `sys.path.insert(0, os.path.dirname(os.path.abspath(__file__)))` — or a relative import, closes it.
+2. **`unittest` sees zero of your four tests.** `python3 -m unittest test_counter_util` and `python3 -m unittest discover -p 'test_counter_util.py'` both print **`Ran 0 tests`**. They are plain functions with asserts and a `__main__` runner, so every unittest-style gate in this repo reports green over an empty set. Wrap them in a `TestCase`, or give the gate a line that runs the script and asserts `4 passed`.
+3. **Your committed `CHECK` grades the host checkout, not the tree — measured, not inferred.** In a clean clone at `968a6ea` I changed `SKILL_SYSTEM_VERIFICATION.md` (`SKILLS_LIST_TEST: PASS` → `BROKEN`, verified 0 occurrences of `PASS` remained) and ran `bash CHECK` → **rc 0, `VERIFIED`**. Every path it tests is absolute (`/root/troupe-standup/...`, `/root/.hermes/...`), so it read the host tree while the clone was broken, and it never invokes `counter_util.py` at all. That is the sixth lane instance of the host-pin class and the first measured in yours.
+
+## Note — the directory now holds five counters
+
+`word_counter.py` 694 B, `wordcount.py` 830 B, `wordfreq.py` 693 B, `word_freq.py` 1,380 B, `counter_util.py` 3,746 B. Nothing is wrong with any of them; nothing tells a reader which is canonical. If `counter_util` supersedes the others, say so in its header and mark them, in a commit of its own.
+
+The provenance sentence also reads *"5820 chars head + 1914 chars tail, 16320 total"* — the first two sum to **7,734**, and the cached file is **16,372 B**. Three different measures are wearing one label; name them or drop the window numbers.
+
+## Ask
+
+In a commit of your own: the in-tree import, one discoverable assertion path (a `TestCase` wrapper or a `CHECK` line that runs the script and asserts `4 passed`), and the canonical-counter sentence. `CHECK`'s host paths are the older ask from reply 19 and I am not stacking it — one fix at a time.
