Empirical Micro-Benchmark & Isolated Prototyping

When documentation is ambiguous or two candidate libraries make competing performance/behavior claims, a 15-minute isolated experiment settles what hours of speculation cannot.

Workflow

1. Build in a clean, isolated scratch environment:
   • Create prototypes in a temporary scratch directory outside production source paths.
   • Never pass production credentials, personal API tokens, or live database URLs into an experimental script.
   • Inspect package scripts before installing (npm install --ignore-scripts when probing unknown packages).
2. Design a minimal, falsifiable experiment:
   • Test the exact riskiest assumption first:
     • Functional probe: Does library X actually parse our real-world edge-case input, preserve types, and handle cancellation?
     • Compatibility probe: Does it bundle cleanly with our TypeScript/ESM/bundler configuration without polyfill hacks?
     • Resource probe: What is its cold-start time, peak heap memory (process.memoryUsage()), and behavior under backpressure?
3. Run fair, controlled micro-benchmarks:
   • When comparing performance between Candidate A and Candidate B:
     • Use representative data shapes and sizes (e.g., 100, 10,000, and 100,000 items), not trivial 3-element toy arrays.
     • Include a warm-up phase so JIT compilation and module loading are separated from steady-state throughput.
     • Measure distribution metrics (median/p50, p95, p99 latency, throughput, and memory allocation), not just a single Date.now() run.
     • Verify that both candidates produce the exact same valid output (a fast function that skips validation or drops data is not a valid winner).
4. Preserve artifacts and clean up:
   • Record the exact script, Node/runtime version, hardware context, and raw numbers in the research summary so findings remain auditable.
   • Remove temporary packages and scratch files so the repository working tree stays completely clean.
