It can check
- Whether JSON parses and fields match the v1 rules
- Whether identity, digest format, claim boundary or index metadata is missing
- Whether deviations remain open, the decision is pending or one person self-reviews
Open engineering references · Local verification tool
Check a FUURAA robotics evidence-package JSON locally in your browser for structure, identity, digest format, claim boundary, evidence index, deviations and independent review decision. The file is not uploaded to FUURAA.
Verification workspace
Choose a local JSON file, paste content, or load one of the three blank examples. Blank examples intentionally show incomplete fields so the review gates remain visible.
Privacy boundary: this tool does not submit, store or transmit the selected file. Continue to handle sensitive evidence under your organisation's rules.
Applicability boundary
FUURAA analysisThe most useful role of automation is to reject structural incompleteness early, not to present a valid format as technical truth. The evidence chain can close only after a recipient recomputes real-file digests from a read-only copy, restores the environment, reviews raw records and signs an independent decision.
