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. httpx.URL.join on a base path lacking a trailing slash replaces the final path segment rather than appending to it
  2. httpx.URL.join with a leading slash resolves to origin and discards all base URL path segments
  3. httpx.URL.join requires a trailing slash on the base URL and a relative path without leading slash to preserve base prefixes
  4. httpx.Client automatically appends a trailing slash to base_url and strips leading slashes from endpoints to preserve path prefixes
  5. httpx.URL.join with relative paths strips base query parameters while query-only joins preserve base paths
  6. httpx.URL.join handles dot segments strictly according to RFC 3986 relative path resolution algorithms
