math.percent_error — Public O2 reproduce pack

Public O2 reproduce pack: recompute published expected values. Does not import the production engine and cannot regenerate a full CVP VERIFIED Manifest.

Compatible execution: Node >=18 / IEEE-754 binary64 percent error
Reference environment: Node 20.19.2 / darwin / IEEE-754 binary64
Bit-for-bit agreement with published expected values is only claimed for the pinned reference_environment. Node >=18 is compatible within the declared ULP contract.

Commands (unzip into one directory):
  node check-percent-error-o2.mjs
  node check-percent-error-o2.mjs --against reproduce.json

Integrity:
  Verify o2-reproduce-pack.zip against bundle.sha256 on the published reproduce.json
  (the copy inside this zip does not include the zip hash). Then check package_files.

Maintainer-only (requires the CalculatorX repository):
  npm run cvp:run -- --capability math.percent_error
