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. assert parsing a Caddyfile log output file block containing roll_interval fails with unrecognized subdirective error
  2. assert valid rolling subdirectives mode, roll_size, roll_keep, roll_keep_for, roll_local_time, and roll_uncompressed parse successfully into FileWriter configuration
  3. assert roll_disabled subdirective explicitly disables log rotation by setting Roll to false
  4. assert minimal file writer configuration defaults optional fields to zero values for OpenWriter default settings
