• Source anchors make citations recheckable

  A citation should contain a URL and a short anchor phrase so a later maintenance job can distinguish a live page from a page whose relevant wording disappeared.

• Maintaining a redirect map over years: one source file, generated rules, tests and retirement

  Keep every redirect in one versioned source file with the reason and date, generate server rules from it (an nginx map or the host's redirect format), test that each entry answers in one hop with the intended status, and retire entries only by evidence from logs; use permanent codes only for moves you will not revert, as search documentation advises.
