Does Obfuscation Break Schema Validation?
A validation schema is a literal in your source; the payload it validates comes from a caller. Protection alone is clean on all five profiles measured. Under member renaming the two sides stop agreeing, and the failure is not a crash: valid requests are rejected for a field the caller never sent, the caller's real field is reported as unknown, and type errors stop being reported at all.

Does Obfuscation Break Webhooks and Signature Verification?
A webhook body is written and signed by a sender you cannot redeploy. Protection alone is clean on all five profiles measured, signature check included. Under member renaming the signature still verifies and the handler goes wrong afterwards: events route to the ignore branch, and a second, entirely different event is silently discarded as a duplicate of the first.

Does Obfuscation Break Analytics Events?
Analytics property names are the one contract where your bundle writes the keys and something you never deploy reads them. Protection alone is clean on all five profiles measured. Under member renaming every read inside the application stays correct and only the JSON leaving the process changes, so nothing breaks except the dashboards, funnels and alerts built on those names.

Does Obfuscation Break Error Codes and errno?
Every error-handling branch in a Node program tests a property the runtime wrote, not one your build did. Protection alone leaves that intact on all five profiles measured. Member renaming turns err.code into undefined, and because no comparison against undefined ever matches, every dispatch quietly falls through to its else branch: missing files become unexpected failures, and a transient error stops being retried.

Does Obfuscation Break JSON Config Files?
The keys in a config file are written by whoever edits that file, and parsing it does not rename anything. Protection alone is clean on all five profiles. Member renaming produces the quietest failure this site has measured: a config file that is present, valid, and completely ignored, while the validator that is supposed to catch exactly that reports no problems at all.

Does Obfuscation Break Command-Line Flags?
A CLI's option keys are built at runtime out of the text the user typed, so they are a contract with a person rather than with your code. Protection alone is clean on all five profiles. Member renaming makes every flag revert to its default without a word of complaint -- including, in the measured run, the safety flag that was the only thing standing between the tool and overwriting a file.

Does Obfuscation Break Saved State and Migrations?
Stored state is the one contract whose other party is your own past build, and it cannot be redeployed. Protection alone is clean on all five profiles. Under member renaming, the measured worst case is not lost data: it is a release that reads yesterday's record one slot out of step, so every value is present, intact, and attached to the wrong name.

Does Obfuscation Break Environment Variables and Build Config?
Protection on its own leaves configuration alone: every arm of an environment-driven config module measured identically across five profiles. Member renaming is where it gets interesting, because an environment variable name is a contract with whatever sets it, and the one build that reads a renamed name does not fail loudly. It silently identifies itself as the wrong release channel.

Does Obfuscation Break JWT and Token Claims?
A token is authored by a server and arrives as base64 JSON, so its claim names are a contract your build does not own. Protection alone leaves them alone. Member renaming produces one loud failure, one silently truncated payload, and an expiry check that stops rejecting expired tokens.

Does Obfuscation Break Child Process and Worker Options?
Node reads spawn and worker option dictionaries inside the runtime, so those key names are a contract your build does not own. Protection alone is clean on every profile. Member renaming produces a child that inherits the whole parent environment, a working directory that is silently wrong, an output cap that stops capping, and a string that quietly becomes a Buffer.

Does Obfuscation Break String Property Paths?
A path written as a string -- a lodash get, a mustache placeholder, a grid column key, a JSON Pointer -- is data, and data is not renamed. The properties it names are. Under member renaming that gap produces a lookup that returns its fallback, a template that shows the placeholder to the user, and a write that lands in the wrong place while the read-back looks merely stale.

Does Obfuscation Break Destructuring and Default Values?
Destructuring survives obfuscation intact in the default configuration, across parameters, nested patterns, array patterns, rest elements and catch clauses. Turn member renaming on and a pattern key becomes a property read like any other, with one specific shape that desynchronises silently and substitutes its default.
