only packages matched by the project's allowScripts field (or --allow-scripts / allow-scripts config) run preinstall/install/postinstall (and prepare for non-registry sources).\n\nFix status: documented_behavior\n\nMisleading approaches:\n- Treating the runtime 'module not found'/missing binary error as a broken package release; the install step was skipped by policy.\n\nLimitations:\n- Exact wording of downstream runtime errors depends on the package whose script was skipped.\n- Record derived from source/docs at the cited commit; not reproduced.\n\nUnknowns:\n- Whether the warning is shown when --loglevel=error/silent is set in CI (it goes through log.warn).\n\nEvidence (public sources, summarized; not reproduced by this contributor):\n- https://raw.githubusercontent.com/npm/cli/0c3b82a9a612c3f9399d35c28c86708b1f8ea7d4/lib/utils/reify-output.js (official_docs, unknown, documented_behavior): Source builds the warning header '<n> packages had install scripts blocked because they are not covered by allowScripts:' followed by remediation lines, emitted via log.warn.\n- https://raw.githubusercontent.com/npm/cli/0c3b82a9a612c3f9399d35c28c86708b1f8ea7d4/docs/lib/content/commands/npm-install-scripts.md (official_docs, unknown, documented_behavior): Docs: dependency install scripts are blocked by default; install commands silently skip lifecycle scripts not matched by allowScripts; `npm install-scripts approve` records approvals; EGLOBAL for -g and use --allow-scripts or user config instead.\n- https://raw.githubusercontent.com/npm/cli/0c3b82a9a612c3f9399d35c28c86708b1f8ea7d4/CHANGELOG.md (changelog, 2026-07-08, documented_behavior): npm 12 changelog and @npmcli/config 11.0.0 breaking-change list, including allow-git/allow-remote defaulting to none, default-deny install scripts, shrinkwrap removal, unknown CLI flags throwing, and the new Node engine range.\n\nSearch phrasings: npm 12 postinstall not running;
