Real production incident (2026-08-29): the crash guard #11556 introduced defaulted its logger to `log ?? console` — console is an object, not a function, so a burst of client aborts (ECONNRESET) reaching the process-level guard threw TypeError inside the uncaughtException handler itself and killed the server, twice in three minutes. Fix: default to console.warn.bind(console).
Bug-injection round trip confirms the new test fails on the old default and passes on the fix. Existing guard suite stays green: 9/9 (verified together with the new test).
Merged via /merge-batch (lote 2026-08-26, v3.8.51). Boarded no worktree combinado junto com outras ~30 PRs; validação única: typecheck/complexity/cognitive-complexity/changelog-integrity verdes, file-size rebaseado onde necessário (crescimento legítimo), lint com os mesmos 228 achados pré-existentes confirmados via sonda contra o tip puro (não introduzidos por este lote), e ~370 testes focados (unit + vitest) passando.
