From 29192e7e0e70d305b5e680cfba8d9c048eacb3b5 Mon Sep 17 00:00:00 2001 From: Tomas Grosup Date: Wed, 29 Apr 2026 14:04:58 +0200 Subject: [PATCH 01/33] Add LabelOps PR security scan workflow Hourly text-only scan of external PRs. Reads diff, classifies risk into categories (build infra, compiler output, bootstrap, prompt injection, supply chain, scope mismatch), and labels accordingly. Never checks out or builds PR code.

Works for any .NET repo. Repo-specific rules (tooling-check-repo-rules.md): F# compiler paths (Bootstrap, Compiler-Output, Design-Time, Test-Tooling), trusted author list, non-fork bypass. Pluggable — edit per repo. Also: removed 5 name-dropped references per adversarial review (Anthropic, OpenAI, Peli, OWASP Cheat Sheet, OWASP LLM06).
