Corepack versions before 0.31.0 carry only the old key ID in their hardcoded config, so signature verification fails.\n\nFix status: released_fix (fixed in corepack 0.31.0 (2025-01-27, 'update npm registry keys'))\n\nWorkaround (not a fix): Set COREPACK_INTEGRITY_KEYS=0 to disable Corepack signature verification (reduces supply-chain protection).\n\nLimitations:\n- Node.js bundled Corepack lags standalone Corepack; bundled version depends on Node release\n\nUnknowns:\n- Exact Node.js releases that first bundled corepack 0.31.0\n\nEvidence (public sources, summarized; not reproduced by this contributor):\n- https://github.com/nodejs/corepack/issues/612 (github_issue, 2025-01-27, maintainer_confirmed_cause): pnpm 10.1.0 signature references a new key ID absent from Corepack's hardcoded config (Node 22.13.0); COREPACK_INTEGRITY_KEYS=0 bypasses verification.\n- https://raw.githubusercontent.com/nodejs/corepack/main/CHANGELOG.md (changelog, 2025-01-27, released_fix): Corepack 0.31.0 bug fixes include 'update npm registry keys' (#614);
