Token {} does not have exactly one deployment manifest ident

Error message

Token {} does not have exactly one deployment manifest identity

What it means

Manifest consistency guard: a pool token address must appear exactly once in the deployment manifest's token list; zero or multiple identities mean the manifest is ambiguous or incomplete for that token.

Solutions

1. Fix the deployment manifest so each pool token has exactly one identity entry
2. Regenerate the manifest from a trusted source
