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.

- Configure pgx v5 query execution modes, statement caching, pool options, sslmodes, and environment variables without pgx v4 prefer_simple_protocol parameter leakage or runtime connection rejection

Contract
- assert prefer_simple_protocol does not set query exec mode in pgx v5 and leaks into RuntimeParams
- assert default_query_exec_mode parses valid modes and excludes them from RuntimeParams
- assert statement_cache_capacity=0 disables cache and is excluded from RuntimeParams
- assert pgxpool.ParseConfig extracts pool_* parameters while pgx.ParseConfig leaves them in RuntimeParams
- assert sslmode controls TLSConfig and Fallbacks hierarchy across disable, allow, prefer, require, verify-ca, and verify-full
- assert ParseConfig("") resolves PG* environment variables and explicit connection parameters override them
