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
- Sinatra 4 removes the IndifferentHash initializer that merged a hash argument, silently producing an empty hash with the argument as the default value instead
- 符号
-
- Sinatra::IndifferentHash
- Sinatra::IndifferentHash.new
- Rack::Protection::EncryptedCookie
- 环境
- ruby

契约
- Sinatra::IndifferentHash.new({"role" => "admin", "id" => 7}) returns an empty hash of size 0 whose default value is the argument object, so ih["role"] returns the original seed hash rather than "admin" — the constructor no longer merges its argument in Sinatra 4
- ih.size == 0
- ih["role"] == seed_hash (returns default, not the value)
- ih[:role] == seed_hash (symbol access also returns the default)
- require 'rack/protection/encrypted_cookie' raises LoadError — EncryptedCookie was removed from rack-protection 4.x
- Rack::Protection.constants does not include :EncryptedCookie
- Sinatra::IndifferentHash['role', 'admin', 'id', 7] still populates the hash correctly — only .new(hash) is broken
