 # AMBER — Sealed-in-Amber Historical Replay Evaluation
 
 `Seal the scene in amber. Retake the exam of that moment.`
 
-**In one line**: we take real past incidents and tasks and have AI models redo them using only what people had in hand at the time. For example, a real operations outage: the model gets only the monitoring and logs of the time, and the evidence revealed afterwards stays sealed. The questions are never published, but every question has a hash fingerprint, and scores and fingerprints are all public, so anyone can check that the questions were not swapped and the scores were not made up.

 ## Same score, different shape
 
 Lanes with the same total can have very different strengths and weak spots. A bigger, darker dot = higher completion; NA = no scorable case on that axis, not a zero.

On deepseek-v4.1-flash @ WorkBuddy direct (W40), the UI axis holds one case, A-d9b79b46, which is on hold and counted as NA, so that cell is NA, not a zero; its vision cell is taken from the re-sit paper after the exam-room fix, see [amber-workbuddy W40](https://github.com/getaskclaw/amber-workbuddy/blob/main/results/2026-W40.en.md). The defense axis is computed with A-d511f9e8 as NA on every lane, so each cell there reflects only the other case (a cell where neither case has a scorable result is NA). On step-5-preview (W41), the UI cell is 1.00: the brand case A-d9b79b46 was re-sat alone on 2026-10-07 after its prompt was revised and passed (12/12), see [amber-stepfun W41](https://github.com/getaskclaw/amber-stepfun/blob/main/results/2026-W41.en.md); its defense and attribution cells are NA because on each of those two axes one case hit the exam-room time cap and has no scorable result.*

 **How to read it**: the hands-on "building" axes are almost full for everyone; the differences are on the "judging" side. Each cell = the lane's completion (0–1) across that axis's cases. The official board on [askclaw.dev](https://askclaw.dev/en/) uses the same ten axes.

-**If cases are private, why trust the scores?** Trust comes from a verifiable process: clean-room exams, per-paper wire audits (a substitute call voids the paper), a closing gate, alias + hash publishing, and a harness pin in every issue (current: [Hermes](https://github.com/NousResearch/hermes-agent)).
