Meaning
The seam reserve is the positive fraction of the local Dirichlet passage cost that remains after partition, boundary-comparison, and catalog-representative errors are subtracted.
If the adverse seam form obeys
with
is the retained seam fraction. It is the margin preventing localization errors from consuming the entire positive passage estimate.
Example (illustrative)
If the positive passage form contributes one unit and the controlled adverse seam terms have relative bound at most
Scope and limits
The reserve is conditional on the stated form bound and common domain. It is not the complete-ground constant, the selector gap, or the passage eigenvalue. Those constants have different owners and cannot be identified merely because they appear in the same product.
