Migration is the real system.

The saved example enters one hundred thousand total accounts and twenty five thousand migrated. Dividing migrated by total gives twenty five percent coverage. Bars share four thousandths of a pixel per account, comparing total four hundred pixels with migrated one hundred. This calculator does not inspect any blockchain, wallet, tooling or actual migration, so an entered migrated count is not proof that signatures or funds are secure. With the same total one hundred thousand, moving the hypothetical migrated count from twenty five to fifty thousand raises coverage from twenty five to fifty percent. Bars share seven thousandths of a pixel per migrated account. If the source window remains twelve months, reaching fifty percent clears its low-coverage flag because the condition is less than fifty. That threshold is an authored planning rubric, not a security certification, migration completion test or schedule guarantee. Even with fifty percent entered coverage, a three-month window triggers the source at-risk label because it is shorter than six months. Bars share fifty pixels per month and compare three with the six-month boundary. At exactly six the short-window condition is false. Zero total accounts takes precedence as inventory required; chain count is displayed but does not change the formula. The source does not implement post-quantum cryptography, validate dependencies or estimate a real quantum threat date.
