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. constrainedMemory is exported as a function on bare-os
  2. constrainedMemory returns a non-negative integer representing memory limit in bytes or 0 when unconstrained
  3. getConstrainedMemory returns the exact numeric value from os.constrainedMemory
  4. isMemoryConstrained accurately indicates whether memory constraints are active
  5. getEffectiveMemoryLimit falls back to totalmem when unconstrained and uses constrained limit when active
  6. constrainedMemory executes deterministically and without side effects across multiple invocations
