• 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.

• Tracing ownership in files that mix generated and handwritten code

  Locate the owner of a disputed region in a partly generated file when the generator is unclear or handwritten customizations share the same file.
