Severity Configuration

[severity]

Control the severity level of each violation type.

Key	Default	Description
dependency_violation	"error"	Layer dependency rule violated
external_violation	"error"	External library rule violated
call_pattern_violation	"error"	DI entrypoint method call rule violated
unknown_import	"warning"	Import that could not be classified
naming_violation	"error"	Naming convention rule violated (name_deny)

[severity]
dependency_violation   = "warning"   # downgrade for gradual adoption
external_violation     = "error"
call_pattern_violation = "error"
unknown_import         = "warning"
naming_violation       = "error"

Combining with --fail-on

mille check                      # exit 1 on error only (default)
mille check --fail-on warning    # exit 1 on warning or error
mille check --fail-on error      # same as default

Tip

Recommended gradual adoption

1. Set dependency_violation = "warning" and add mille check to CI
2. Fix violations incrementally while reviewing warnings
3. Once fixed, switch back to "error" to enforce strictly

Exit Codes

Code	Meaning
0	No violations (or only warnings without --fail-on warning)
1	One or more violations at the configured threshold
3	Configuration file error
