Included changes

  1. 01The public workbench verifies the exact timestamp and raw-body signing input locally without submitting or persisting entered values.
  2. 02The read-only verification-kit endpoint publishes header names, signing format, a deterministic public test vector and Node/Python examples.
  3. 03Strict helpers reject empty secrets, malformed headers, invalid timestamps, stale messages and signature mismatches.
  4. 04The static vector is identified as a historical signature-compatibility fixture with a fixed freshness reference.
