Summary: Finding the leakage rate where a protective dormant reservoir stops buffering modular quasispecies against strong recombination.

Dormant reservoirs can preserve diversity by storing genetic material away from immediate selection, but leakage out of that seed bank may erode the protection. This experiment asks how much leak can occur before a modular quasispecies loses localization under already strong recombination.

The script builds a dense symmetric operator coupling active and dormant states, fixes both mutation and recombination, and then bisects the leak rate until modular localization breaks down. Because the full operator is twice the active-state dimension, the BOINC workflow is especially helpful for carrying the threshold bracket to larger sizes.

This matters because dormancy and recombination are usually discussed separately in quasispecies-style models. The experiment quantifies how strongly a seed bank must retain material to continue acting as a buffer against delocalization.

Method: Dense symmetric eigensolve of a coupled active-dormant operator with iterative deepening and bisection on seedbank leak rate.

What is measured: Critical leak threshold, localization score, peak module mass, dormant mass fraction, leading eigenvalue, fixed mutation and recombination levels, and bracket width.
