KISS/DRY sweep — drops ~90 LOC with no behavior change. - circularBuffer: drop unused pushAll/toArray/size; fold toArray into drain - gracefulExit: inline Cleanup type + failsafe const; signal→code as a record instead of nested ternary; drop dead .catch on Promise.allSettled; drop unused forceExit - memory: inline heapDumpRoot() + writeSnapshot() (single-use); collapse the two fd/smaps try/catch blocks behind one `swallow` helper; build potentialLeaks functionally (array+filter) instead of imperative push-chain; UNITS at file bottom - memoryMonitor: inline DEFAULTS; drop unused onSnapshot; collapse dumpedHigh/dumpedCritical bools to a single Set; single callback dispatch line instead of duplicated if-chains - entry.tsx: factor `dumpNotice` formatter (used twice by onHigh + onCritical) - useMainApp resize debounce: drop redundant `if (timer)` guards (clearTimeout(undefined) is a no-op); init as undefined not null - useVirtualHistory: trim wall-of-text comment to one-line intent; hoist `const n = items.length`; split comma-declared lets; remove the `;[start, end] = frozenRange` destructure in favor of direct Math.min clamps; hoist `hi` init in upperBound for consistency Validation: tsc clean (both configs), eslint clean on touched files, vitest 102/102, build produces shebang-preserved dist/entry.js, performHeapDump smoke-test still writes valid snapshot + diagnostics.
