The chain is the unit of trust.
A single decision can be explained away. A chain of linked decisions cannot. This is the same four-step case, full size — including a time axis, the attempt to insert history, and a reading guide for what a link means.
One case, reconstructed across eleven days.
One event tells you what happened. The chain tells you why.
You can't insert history. The chain proves what happened.

Each decision in a case points back to the specific decision before it. The later step cannot stand on its own — it is bound to that prior record.
Before a link is accepted, the system checks that the referenced prior step is genuinely part of the case's recorded history. No history, no link, no admission.
Given the stored records, the whole case can be re-derived — every step, every reason, every link — and the reconstruction is compared against what was recorded.
If a proposed step claims a connection that cannot be found, it fails closed at that boundary — as the insertion attempt above demonstrates. The reason is recorded too.
