TDD enforcement and guardrails for Claude Code, Codex, and GitHub Copilot CLI

Real-time behavioral enforcement for Claude Code. Monitors AI actions, detects violations, and interrupts misbehavior. Also has a cute pet.

Fable-style spec + evidence gate for Claude Code + Codex. Makes Opus/Codex work under Fable-like discipline: blocks every edit until a deterministic spec passes, and there is no "done" without live acceptance evidence. Spec-first, verification-gated, forbidden-paths enforced.
