the discovery residual is charged against a declared hypothesis space, and its obstruction is the cell gap

Agent-decided, reversible; a research-branch finding (PR #101, third pass), not canonical. The manipulation side's last open quantity, the adverse mass of true declared reasons no independent inquiry puts on the docket in time, is stated as the omission gain of the undiscovered adverse reasons and certified by their conditional adverse sensitivity above the docket; its exact worst-case value with unbounded inquiry budget is the largest information-cell gap of the declared repertoire, and with a budget it is a decision-tree minimax value with no closed form, the needle instance refuting any fractional-progress theorem for direct queries. The bound is taken to be Γ-valid relative to a declared hypothesis space of reason states, so that the fully-informed comparator becomes a bounded ideal without an oracle, and adequacy of that space is carried as the ontology wall rather than as a residual. The frontier — undetermined reasons of positive conditional adverse mass — is recorded as the engine's obligation. The alternative rejected: an "interface-incompleteness mass", for which the declared representation supplies no measurable object.
