LISR Changelog
Every LISR score, framework revision, and methodology change is dated, versioned, and locked at publication. This changelog is the public record. Entries cannot be retroactively altered — corrections are published as new dated entries.
LISR-ACR-v1.0 — Second Agentic Protocol Score: Google AP2 — 6.4 / HIGH
Second independent agentic protocol custody score. Scored against Linkmerica's dated monitoring record (June 15 – July 12). Qualitatively different risk profile than AP4M: AP2's risks are visible and research-validated (demonstrated prompt injection attack, no native mandate revocation) rather than undisclosed. linkmerica.com/protocols/google-ap2/
New Wallet: Foundation Passport Prime — LISR 4.1/MODERATE, QRR 7.3/HIGH
Sixth wallet added to the LISR index. First device with an independent published hardware security audit (Keylabs) and the first with designed-in wireless connectivity. QRR assessment declined to credit the manufacturer's unverified "post-quantum encrypted" marketing claim absent named algorithms or independent validation. linkmerica.com/wallets/passport-prime/
Tangem Rescored — 5.8/MODERATE → 6.8/HIGH
First tier-changing rescore since founding. Driven by Ledger Donjon's July 10, 2026 disclosure of an unpatchable laser fault-injection vulnerability enabling password reset and fund drainage. No firmware update mechanism exists to remediate. linkmerica.com/wallets/tangem/
LISR-ACR-v1.0 — First Agentic Protocol Score: Mastercard AP4M — 6.9 / HIGH
The first independent agentic protocol custody score in existence. Scored against Linkmerica's dated monitoring record (June 11–28). Primary finding: absence of public disclosure on session key scoping, guardrails, and multi-party approval. linkmerica.com/protocols/ap4m/

Fifth research brief — nine months of AP2 adoption data and the authorization custody risk category. linkmerica.com/research/google-ap2/
Research: AP4M 30-Day Follow-On Published
Fourth research brief published — the first institutional research document built entirely on a dated monitoring record (June 11–16 sweeps). linkmerica.com/research/ap4m-30-days/
LISR-QRR-v1.0 — First Quantum Resistance Scores Published
First independent quantum readiness scores for hardware wallets: Ledger 6.8/HIGH, Trezor 7.8/HIGH, Tangem 9.1/CRITICAL, SafePal 8.3/CRITICAL, ELLIPAL 8.7/CRITICAL. Published to all wallet pages.
LISR v1.0 Score: ELLIPAL Titan — 6.4 / HIGH

Five federal EO compliance milestone targets added to the agentic monitor following Executive Orders 14412 and 14413 (June 22, 2026). Watch-list changelog entry 5.
Research: Quantum EO Brief Published
Analysis of EO 14412/14413 implications for hardware wallet custody. Linkmerica published independent quantum research June 15 — one week before federal policy validated the thesis.
LISR-ACR-v1.0 — Agentic Custody Readiness Dimension Scaffolded
Six-category framework for rating agentic protocol custody risk. First protocol scoring: AP4M, July 2026. Framework version-stamped and locked.
LISR-QRR-v1.0 — Quantum Resistance Readiness Dimension Scaffolded
Five-category quantum readiness framework version-stamped following compressed Q-Day timeline research (March 2026).
Research: Quantum Readiness Gap Published
First independent institutional quantum readiness assessment of hardware wallet custody infrastructure. Published one week before EO 14412/14413.
Research: AP4M Custody Risk Analysis Published
First independent institutional custody risk analysis of Mastercard AP4M — published the day after launch. Agentic infrastructure monitoring begins: 13 targets.
LISR v1.0 Scores: Ledger, Trezor, Tangem, SafePal
First four LISR v1.0 scores published and locked: Ledger 4.8/MODERATE, Trezor 4.7/MODERATE, Tangem 5.8/MODERATE, SafePal 6.4/HIGH.
