After hours of probing, the culprit wasn't the main inductor or the output caps. It was the relative to the schematic. The schematic shows a quiet ground (AGND) and a power ground (PGND) tied at a single star point near the output return.
Especially in large organizations or open-source projects, colleagues or community forums might have discussions or documentations that illuminate the purpose and story behind specific identifiers.
