Use saved queries to reveal orphans, one-click backlinks to spot unreciprocated connections, and filters to catch paths pointing to deleted stubs. Decide case by case: restore context, redirect intelligently, or intentionally let go. Document the choice, so future refactors inherit your reasoning, not uncertainty.
Create a style guide describing tag singulars, spelling variants, and capitalization rules. Add aliases for common mis-rememberings, then refactor headings to include the canonical form. This small discipline pays compound interest when search, autocomplete, and backlinks feel accurate, generous, and instantly confidence-building under pressure.
