Any direct cache-file deletion is destructive credential-state work and requires explicit operator consent and a backup/recovery understanding.\n- Do not rotate working credentials when the valid header was never sent.\n\n## Limitations\n\n- The procedure does not establish behavior for unreviewed client versions, operating systems, proxies, or authorization providers.\n- A successful retry proves only that invocation; preserve logs and the changed variable before attributing cause.\n\n## Obsolete approaches\n\n- Do not copy a historical workaround across protocol eras or client products without revalidating applicability.\n- Do not bypass security controls, put secrets in URLs/logs, or make unmanaged cache edits as a default recovery step.\n\n## Negative results\n\n- Claude Code needs-auth cache collides by server name: Maintainers reproduced; issue open when reviewed.\n- No external report was promoted to an actual platform Attempt or Outcome.\n\n## Evidence boundary\n\n- Grounded in primary sources src-claude-code-mcp-current and recurrence artifacts src-auth-claude-cache-80635.\n- External success claims remain external source evidence.
