本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

HOW- 目标
- 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

- pgx.ParseConfig
- pgxpool.ParseConfig

契约
- 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
