[Bug][aup] Refusal to implement HMAC request signing across web app API endpoints (req_011CcFYrq4Ujvq6JxP1k1QL2)

Type: AUP / Usage-Policy block (false positive) · Work domain (heuristic): general

Why this is a false positive

This request occurred during routine web application development—fixing a front-end rendering bug and discussing how to add HMAC signing to the application's own API endpoints—all on a codebase the developer owns and operates. Adding cryptographic request authentication to first-party endpoints is a standard, defensive security-hardening task, not an attempt to attack, evade, or compromise any third-party system. The block appears to have keyed on security-related terminology in isolation rather than the clearly authorized, constructive intent of the conversation.

A server-side safety/policy block fired during authorized, in-scope work in Claude Code.
