The DL module's cells were module-level asserts: run_lane_tests.py --list reports unittest=0 bare=0 for test_damerau_levenshtein.py, so no named case moved when the module broke. CHECK_DL runs the shipped cells plus oracle_dl.py, which grades a deterministic 5300-pair corpus against a BFS over the edit graph (the definition of true DL) and proves in the same run that the corpus reds both classic impostors (OSA, plain Levenshtein). Measured: green on the tree (0/5228 mismatches, 42 OSA witnesses, 252 Lev witnesses); rc 1 with named witnesses on a transposition-deleted mutant and on an OSA module.

# CHECK_DL: gate for wizard-work/beam/damerau_levenshtein.py (Q133-DL).
|
|
#
|
|
# Why this file exists (2026-10-31). The DL module and its cells landed in
|
|
# 5bded80, but nothing pinned the *property* the module exists for: the cells
|
|
# are module-level asserts that run only when the file is imported, and
|
|
# `run_lane_tests.py --list` reports `test_damerau_levenshtein.py unittest=0
|
|
# bare=0` -- zero named cases, so the gate's per-test count never moves when
|
|
# they break. This gate names the work: the shipped cells run as a script, and
|
|
# an independent BFS oracle (oracle_dl.py) grades a deterministic corpus against
|
|
# the module and proves, in the same run, that the corpus can red the two
|
|
# implementations people ship by mistake (OSA and plain Levenshtein).
|
|
#
|
|
# Exit codes follow the repo's tools/ contract:
|
|
# 0 clean, 1 graded a fault, 2 could not grade.
