Wayback checker

Checks whether name.[tld] has a usable history on the Wayback Machine. For each TLD it queries the CDX API for up to the configured number of non-error snapshots: hitting that cap means the combination resolves as valid, fewer means low-content, none means dead.

Status	TLD	Hits	Time	Host

"Valid" means the hit count reached the configured cap, "low-content" means some hits but fewer than the cap, "dead" means none. Results are cached for 5 minutes per host; the recheck button always fetches fresh, and any errors left after a run are retried automatically once.
