High-Leverage Promises
Promises ranked by combined dependent count and structural bridge score (betweenness centrality).
Structural Diagnostic
Five-field analysis: epidemiology · FMEA · information theory · incentive alignment
Cascade Risk
A single violation is unlikely to cascade beyond its direct dependents.

Top Risk Promises
Ranked by Risk Priority Number (RPN = Severity × Occurrence × Detection). Network reliability: 11.3%.
Severity 10 · Occurrence 10 · Detection 5
High severity: failure cascades to 6 downstream promises across 3 domains. High likelihood of failure based on current status (violated). Moderately detectable: verification is filing.
Severity 10 · Occurrence 7 · Detection 3
High severity: failure cascades to 5 downstream promises across 2 domains. High likelihood of failure based on current status (degraded). Easily detected: verification is audit.
Severity 6 · Occurrence 10 · Detection 3
Moderate severity: failure cascades to 2 downstream promises across 2 domains. High likelihood of failure based on current status (violated). Easily detected: verification is audit.
Severity 5 · Occurrence 7 · Detection 5
Moderate severity: failure cascades to 2 downstream promises across 1 domain. High likelihood of failure based on current status (degraded). Moderately detectable: verification is filing.
Severity 1 · Occurrence 10 · Detection 10
Low severity: failure cascades to 0 downstream promises across 0 domains. High likelihood of failure based on current status (violated). Hard to detect: verification is none.

Assessment
The JCPOA is a textbook case of cascade from hub failure. The US sanctions re-imposition (JCPOA-011, the highest-leverage node at Bridge score 1.00) triggered violations across 6 downstream promises in 3 domains. Network health collapsed from an estimated 75+ at signing to 14/100 today. What makes the JCPOA structurally distinct from HB 2021 is its verification-status correlation: the JCPOA had the most sophisticated verification infrastructure in arms control history (IAEA continuous monitoring, sensor verification, Additional Protocol access), and it still collapsed. The computing regime dominated (64% of promises in computing dynamics) — failures were detected rapidly. But detection couldn’t prevent the cascade because the cascade source was political, not operational. The verification infrastructure was itself a set of promises that depended on the political promises that failed first. When the political layer violated, the verification layer lost its authority. The JCPOA proves that verification quality alone doesn’t save a network — the verification layer must be structurally independent of the political layer, not nested inside it.
Lindblad projection: Based on the open quantum systems master equation fitted to 67,027 institutional commitments, 1 promise in this network is in composting dynamics (slow resolution, Zeno-sensitive) and 14 are in computing dynamics (observation-driven resolution). 1 promise is at risk of Zeno freeze — it is being monitored too frequently relative to its natural resolution timescale.
1 promise has no structural pathway to resolution
No dependencies, no verification. Adding a dependency connection or verification mechanism would move it out of stasis.
