// Decision Autopsies · Boardroom Reality Checks
Six decision autopsies and five boardroom reality checks, each mapped through the Decision Integrity Chain™. Documented cases draw on public records; constructed cases illustrate recurring institutional patterns.
// Decision Autopsies — The Record Shows
Seeing these patterns in your institution?
The Decision Drift Audit reconstructs how critical decisions move from board intent to execution — and identifies exactly where the chain breaks.
// About the section above
Decision Autopsies — composite cases constructed from documented institutional failure patterns. Not tied to any specific named institution beyond what is explicitly stated. Analytical and educational in nature.

// 01 · Diagnosis — what the data shows
The decision sequence had to be reconstructed after the collapse, when the opportunity to intervene had already passed.
DIC™ L6 — no replay infrastructureA deployment decision made and executed. No verification record. No reachable kill switch. The institution could not prove what had been authorised at the moment trading began.
DIC™ L6 — no deployment decision recordPatient-facing deployment before independent validation. No traceable link between result and machine. The record that would have made it defensible was never built.
DIC™ L6 — no clinical deployment decision recordEvery LDI fund was individually compliant. No single decision wrong. No feedback loop at network scale.
DIC™ L8 — no cross-institutional feedbackAcross several failures analysed, much of the eventual loss arose after the original error, when the institution could not detect, reconstruct or stop what followed.
This is the governance gap Decision Engineering™ is designed to examine.Most institutions can explain decisions. Few can replay them. The audit identifies which of yours cannot be reconstructed — in 10 days.
Start the audit →Each case is mapped in full through the DIC™ — the layer that broke, the decision that could not be stopped, and the structural change that would have prevented it. Not commentary. Architecture.
Read the six case autopsies →Every term used across this work — replayability, the Decision Integrity Chain™, the Fiduciary Gap™, decision drift — is defined once in the glossary.
