Use unique HTTP(S) documentation links with descriptive labels and short notes beside list links. Fix confirmed HTTP 404/410 destinations in the sample below. Access-denied, rate-limited or timed-out checks are unknown, not confirmed broken. Request a recheck after changes; more links alone earn no extra points.
