Built-in IL Normalization — Rules apply in the listed order to all IL text, preserving each matching prefix and replacing only its build-variant value.

ILNormalizeContainingStrings — Matches are replaced in the listed order with a comparison-local marker absent from both inputs; all other text remains comparable.

Warnings

[ ! ] IL substring configuration safety warnings (1)

• ILNormalizeContainingStrings: "buildserver1_" and "buildserver1_artifact" overlap by containment. Configured normalization uses sequential ordinal matching on unreplaced raw text in listed order; inserted markers are not reprocessed, but the result may still depend on rule order. Use non-overlapping values or verify the reported application order.
