X_HELPER_COPY
Means
shipped source carries a second implementation of a helper that has one home
Typical cause
the rows of scripts/lib/helper-homes.ts — fnv1a, fingerprint, render's contentHash (xxHash32), escapeHtml, readCookie, PgExecutor, storeMode — each replaced copies that had already drifted: four HTML escapers with four character sets (the dev dashboard's escaped no quotes), three cookie readers, four PgExecutor declarations, an environment ternary per app. Matched on SHAPE — FNV's constants as values, an unkeyed hasher fed canonicalJson, a replacement writing &, a ; split walking name=value, the method declared — never on the name. Or a second import PATH: a value another @ultimat3/* package exports, re-exported in any spelling (pinned exceptions: scripts/lib/package-reexports.ts), or a blind export *
Fix
import the helper or value from the package the finding names (contentHash: @ultimat3/render/server) and delete the local implementation or the re-export — for export *, export each value by name — then bun run flight-copies
