// Decision Autopsies · Boardroom Reality Checks

Real failures. Every layer mapped.

Six decision autopsies. Five boardroom reality checks. Each one traces a real institutional failure through the DIC™ — showing exactly which layer broke, when, and why nobody saw it coming.

// Decision Autopsies — The Record Shows

DA-2025-001 · Credit · UK GSIB
640 loans approved. Every dashboard green. Credit committee signed off. The exposure was invisible — until it wasn't.
The model scored correctly. The rules were followed. The intent was never encoded. L3 was absent for 14 months before anyone asked the right question.
DIC™ layer that broke: L3 Intent — L4 Rules (drift between intended and executed policy)

DA-2025-002 · Home Health · US Healthcare
Scheduling algorithms optimised for efficiency. Patient outcome indicators deteriorated across an entire region. No single decision was wrong.
Every individual scheduling decision was defensible. The emergent pattern — resource concentration, outcome drift — was visible only at L7. Nobody had designed a feedback loop.
DIC™ layer that broke: L7 Outcome — L8 Feedback (no mechanism to detect emergent harm)

DA-2025-003 · Acute Care · Hospital Network
Triage protocols updated. Clinical judgment delegated to a scoring engine. Outcomes shifted — not dramatically, but consistently and in one direction.
The scoring engine was validated. The delegation was not auditable. L5 Judgment was fully automated without an authority boundary being defined.
DIC™ layer that broke: L5 Judgment (authority scope undefined at delegation)

DA-2025-004 · Onboarding · Asian Digital Bank
KYC pass rates were improving. Fraud rates were also improving. Regulatory findings arrived two quarters later about a segment that had been systematically under-screened.
The rules were consistent. The intent behind the rules had changed — but only in board documents. L3 was updated in policy. L4 was not re-encoded. The gap was 8 months wide.
DIC™ layer that broke: L3–L4 gap (intent updated in policy, not in rules)

DA-2025-005 · Pricing · Regional Insurance Group
Algorithmic pricing delivered margin improvement. Three segments were systematically disadvantaged. The pricing model had never been reviewed for fairness.
L1 Purpose stated "fair outcomes for customers." L4 Rules optimised for margin. The contradiction had been operating for 22 months before a regulatory inquiry surfaced it.
DIC™ layer that broke: L1–L4 contradiction (purpose and rules in direct conflict)

DA-2025-006 · Agentic Credit · Cross-border Platform · In progress
Seven agents. Three jurisdictions. Seven seconds. One outcome that no institution authorised.
Based on the scenario constructed in Paper 3 — When the Protocol Decides. Publishing shortly.
DIC™ layers that broke: L3 · L4 · L5 · L8 — simultaneously, across institutions
