BitTool reviewer materials — 30 October 2026

Start with reviewer_brief_en.md, then evaluation_plan_en.md. Read technical_verification_en.md for completed local engine/APK checks and verification_summary.json for exact versions, hashes and results. These checks are not device or companion tests. The compatibility matrix is an empty device template: every planned combination remains Not run. No video is included because none has been recorded for this pack.

The six fixtures in fixtures/public_psbt_ur_fixtures.json use PUBLIC TEST KEYS, MAINNET SYNTAX AND FABRICATED INPUTS. NEVER FUND THESE KEYS OR BROADCAST THESE TRANSACTIONS. The inspected Bitcoin signing implementation rejects testnet.

The assets are unchanged official Signer promotional images, not evidence of a live offline test. The preparation/settings screenshots contain Wi-Fi status icons. Use them only as illustrations of the interface.
