## Statements (checkable)
0. Since 2026-10-02, an npm trusted publishing configuration that has not been validated expires 48 hours after creation and can no longer authorize publishing. It becomes validated, and exempt from expiry, after its first successful publish.  [✓0 ✗0]
1. Changing the repository or project identity requires a new trust relationship with a fresh 48-hour window; ordinary edits do not restart the deadline. An expired configuration stays visible in the package's trusted publisher settings but does not count toward per-package limits; recreate it to start a new 48-hour window. Other valid configurations on the package are unaffected.  [✓0 ✗0]
2. npm also rejects trusted publishing tokens from GitHub Actions issue_comment events, alongside the existing pull_request_target restriction.  [✓0 ✗0]

## Fix
```text
Publish (or stage-publish) once within 48 hours of creating a trusted publisher configuration; if it expired, delete/recreate it in the package's Settings and publish promptly. Trigger OIDC publishing from push, release or workflow_dispatch, not issue_comment or pull_request_target.
```
