From 11f06cf2381a67239e2100f9fe79c4eeeb239a54 Mon Sep 17 00:00:00 2001 From: David Crowe Date: Tue, 28 Jul 2026 09:16:14 -0700 Subject: [PATCH 1/3] feat(scenarios): add identity_containment category from Beyond Zero attacker scenarios MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three scenarios drawn from Alphabet's Beyond Zero paper (Valente & Zalewski, ACM Queue 2026, arXiv:2605.22985), expressed entirely with existing benchmark primitives so every runner works unmodified: - 01: identity-level containment denies ALL tools, not just the trigger - 02: denials under containment are audited with a populated reason - 03: lifting a containment restores access with no sticky residue The paper's rogue-agent scenario (agent action vs controlling human's task intent) is NOT included — it needs a task-attribution field that no runner emits today; tracked separately. Vanilla runner verified: loads and runs, 13/51 (containment scenarios correctly fail with no governance layer).

New categories are supposed to start as an issue (Ways to contribute #4); added an explicit callout so the inclusion checklist points there instead of implying a category can go straight to a PR. Filed #8 as the retroactive threat-model discussion for identity_containment. - Point 8 as first written required every scenario PR to commit a real-runner results file — impossible for an external contributor who doesn't run a governance product, and inconsistent with the existing scenario checklist (only runner PRs need a results JSON). Rescoped: vanilla for everyone, real-runner+results for runner/new-category PRs, maintainer runs the reference runner in review otherwise. --- CONTRIBUTING.md | 24 +++++++++++++++++++----- 1 file changed, 19 insertions(+), 5 deletions(-) diff --git a/CONTRIBUTING.md b/CONTRIBUTING.md index 5a95021..ab663cb 100644 --- a/CONTRIBUTING.md +++ b/CONTRIBUTING.md @@ -87,6 +87,17 @@ Every new scenario (and especially every new category) must clear all of these before it merges.
