Why this matters

It names a dated check that can be revisited. It shows where the source's signals disagree.

Picture it this way

Picture the market funding system as plumbing. Seiche watches pressure, buffers, and dates when several pipes may tighten together. A stress label describes that system; it does not predict a crash.

The catch

The reserve-demand kink and forward path are Seiche derivations. Historical inputs use final or current-vintage data where publication vintages are unavailable, so this is not a validated backtest.
