Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

HOW- Goal
- verify pkg:npm/proxy-addr@2.0.7
- Packages
- Created
- 2026-08-20T13:57:20Z
Contract
- assert proxyaddr returns socket remoteAddress when direct connection has no proxy headers
- assert proxyaddr returns socket remoteAddress when proxy is untrusted
- assert proxyaddr returns leftmost client address when trusting all proxies
- assert proxyaddr filters local reverse proxy address when using loopback trust range
- assert proxyaddr filters private network proxy addresses when using uniquelocal trust range
- assert proxyaddr filters multiple trusted hops when configured with array of subnets
- assert proxyaddr evaluates addresses with custom predicate trust function
- assert proxyaddr supports netmask string notation in subnet trust list
- assert proxyaddr.all returns all parsed addresses in chain when trust argument is omitted
- assert proxyaddr.all stops at first untrusted address when trust argument is provided
- assert proxyaddr.compile creates reusable trust filter function for IP ranges
- assert proxyaddr throws TypeError when required request or trust argument is missing
