batch-type-ksh-scripts

Recover business rules from ksh (and adjacent POSIX shell) batch drivers -- argument parsing, exit-code contracts, trap/signal handling, file locking, and retry/backoff loops -- as first-class rules rather than incidental scripting. Use as the batch-type/ksh-scripts reader within recover-business-rules whenever a batch job is driven by a ksh wrapper, alone or in front of a Spring JAR or a call into stored procedures.
