History
Marcus Summers e1767bc19e Add troubleshooting article: Permission denied (publickey) after key rotation 
New 05-troubleshooting/networking article covering the per-host nature of
authorized_keys: rotating a workstation SSH key requires backfilling the new
pubkey to every host, or hosts holding only the old key reject it with
Permission denied (publickey). Includes fleet-sweep diagnosis, idempotent
backed-up backfill via a still-trusted transit user, and prevention. Wired
into SUMMARY.md nav.
