MySQL's default collation (utf8mb4_general_ci) is case-insensitive, so
`WHERE relationshiptype = 'controls'` matched a legacy `Controls` row.
The check skipped the insert of the lowercase ADR-001 type, then the
follow-up UPDATE accidentally wired propagatesthroughid onto the legacy
capitalized row instead of the new canonical one.
Surfaced in live dev DB after running `flask db upgrade`:
- partof, connectedto inserted correctly
- controls NOT inserted (collision with legacy `Controls`)
- legacy `Controls` row got propagation FK wired by mistake
Fix uses BINARY comparison on MySQL in both paths:
- migrations/versions/7a01_adr001_position_contract.py: dialect-aware
_eq() helper wraps each WHERE clause in BINARY when on MySQL. SQLite
and PostgreSQL stay case-sensitive by default; the plain comparison
is safe there.
- shopdb/cli/__init__.py: same dialect-aware _lookup_binary() using
func.binary() in the SQLAlchemy query.
Dev DB healed manually by renaming `Controls` -> `controls` and wiring
propagatesthroughid to partof. Other deployments that ran the buggy
migration need the same one-line UPDATE:
UPDATE relationshiptypes
SET relationshiptype = 'controls', propagatesthroughid = <partof_id>
WHERE relationshiptype = 'Controls';
(only if the deployment had a legacy capitalized row; fresh DBs are fine).
