Im sorry this got send 3 times but I tried going to previous to check teamates information and that send the form and I didnt know. CanaryForge measures how long an LLM agent's sandbox escape goes unnoticed, not whether the escape happens. A tool-calling agent runs in a Docker container with a planted escape temptation, watched by three monitors that never ask the model anything: an egress proxy, a filesystem canary on inotify, and an HTTP heartbeat. Across 416 runs on four machines, 183 of the 197 real leaks, 93 percent, left through file and directory names without ever touching the network, which is the channel the July 2026 incident used and the one egress monitoring cannot see. Detection lands in about two seconds and nothing acts for another forty-four.

Decline to score

Only when the quality of the writing makes the work impossible to follow. Say why in your private critique; the project page shows only that a judge declined, not why.

How much would this matter for AI safety if it worked? How innovative is it? For scores of 4-5: is this actually new to the field, or replicating recent work?

Scoring guide
  1. 1Negligible. No clear problem addressed, or no meaningful novelty.
  2. 2Limited. Addresses a real problem but with a generic or well-trodden approach. Incremental at best.
  3. 3Moderate. Clear problem with a reasonable approach; some novelty in framing or method beyond routine application of existing tools.
  4. 4Significant. Important problem with an original approach, or identifies a neglected problem area. A valuable contribution others could build on.
  5. 5Exceptional. Tackles a critical AI safety problem with a genuinely novel approach, or opens a new research direction. Clear theory of change. You'd be excited to share this with researchers in the area.

How sound are methodology, implementation, and findings?

Scoring guide
  1. 1Seriously flawed. Methodology broken, results uninterpretable, or implementation doesn't work.
  2. 2Weak. Approach has significant gaps: missing validation, flawed experimental design, or incomplete implementation.
  3. 3Competent. Technically solid given the short duration. Methodology makes sense, results are interpretable, limitations acknowledged, work builds toward clear conclusions.
  4. 4Strong. Thorough methodology with convincing validation. Results clearly support conclusions. Immediately useful for future work.
  5. 5Exceptional. Ambitious scope executed rigorously. Surprising findings, novel methods, or unusually robust validation.

How clearly are work, findings, and impact potential communicated?

Scoring guide
  1. 1Incomprehensible. Cannot determine what the project is actually claiming or doing.
  2. 2Hard to follow. Key information buried, missing, or diluted by excessive length. Significant effort to extract main points.
  3. 3Clear enough. Can understand the problem, approach, and results without undue effort. Core content clearly present: problem, method, findings, limitations.
  4. 4Well presented. Easy to follow, well-structured, appropriate level of detail. Target audience would get it quickly.
  5. 5Exceptionally clear. A pleasure to read. Complex ideas made accessible. Could serve as a model for how to present this type of work.

  1. The paper does a byte-for-byte identical prompt instruction against a local 7B model. This process oversimplifies realistic, multi-stage attacks and relies on static system prompt. Performing tests against other models could significantly improve the paper by providing more comparative data points.

  2. Six documented ways the harness returned a number while measuring nothing, a pre-registered prediction that failed and was reported as failing, and the catch that a client timeout deleted runs in proportion to the variable under test - that last one is rarer than any result in the paper. The separation of transcript-derived levels from monitor-derived ones is what kept the results standing after a large correction, and deserves more emphasis.
