Do not batch unrelated removals - a regression must point to one change.\n2. **Gather static evidence.** Run the language's dead-code detector (ts-prune or knip for TS\u002FJS, vulture for Python, `deadcode` for Go) and a dependency grapher (madge) or IDE \"find usages\". Record what each reports unreachable.\n3. **Gather runtime evidence.** Check production coverage or profiling data over a representative window - at least 30 days for user-facing paths, 90+ days for code tied to monthly or quarterly jobs - and telemetry: was this endpoint, job, or branch hit this quarter? A symbol is a deletion candidate only when static analysis AND runtime evidence agree. One signal alone produces false positives that take down prod.\n4. **Hunt the dynamic callers static tools miss.** Grep the symbol name as a *string* (reflection, string-keyed dispatch, serialization). Check DI containers, registries, ORM hooks, cron\u002Fqueue workers, and feature-flag config. Search infra repos and other services. Public API surface and library exports are reachable by definition unless you control every consumer.\n5. **Classify the kind of dead, because each is removed differently.** Unreachable (no path calls it) → delete. Unused (callable, never called) → delete. Redundant (duplicates a live path) → repoint callers first. Dormant-behind-a-flag (flag off for a cycle) → retire the flag first, then delete its branch.\n6. **Soft-delete risky removals first.** Replace the suspect path with log-and-throw, or gate it behind a kill flag while keeping the code, for one full business cycle - 30 days minimum, 90 for anything touching monthly or quarterly processes. If nothing fires the log, proceed. For low-risk leaf code, skip to step 7.\n7. **Delete in a focused PR.** Remove the code AND its tests, fixtures, config, flags, and now-orphaned imports.
