"""Smoke test for the two-axis classifier.
|

|

The full smoke test — run ``classify()`` over the sample export
|
||||
(~/Downloads/_documents/Sheet1-1.xlsx) and assert "Other" <= ~10% with known
|
||||
fixtures landing in the right buckets — is added in Phase 2 (docs/BUILD.md) and
|
||||
owned by the classifier-engineer agent. This placeholder keeps the test layout
|
||||
in place and guards the classification constants.
|
||||
Runs the DETERMINISTIC ``classify()`` (no Haiku, no network, no AWS) over the
|
||||
canonical sample export and asserts the two-axis model keeps "Other" in the
|
||||
single digits, plus a handful of known fixtures land in the right bucket. The
|
||||
Haiku fallback is never exercised here.
|
||||
|
||||
Canonical fixture: ``~/Downloads/_documents/Sheet1-1.xlsx`` (347 rows, 13 cols).
|
||||
If the file is absent the export-driven tests skip. Run with the repo venv:
