This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. parse parses CSV rows into arrays of string fields by default
  2. parse maps the first row to object keys when headers is true
  3. parse applies custom header names when headers is an array
  4. parse transforms header names when headers is a transform function
  5. parse parses custom delimiters such as semicolon
  6. parse trims whitespace from fields when trim is true and ignores comments
  7. parse limits the number of parsed rows when maxRows is specified
  8. parse applies row transform function via transform method
  9. parse validates rows and emits data-invalid for invalid rows via validate method
  10. parse emits error event on unclosed quotes
  11. parse throws error on column header count mismatch when headers is true
