Size a protected unassigned reserve only after confirming that primary analyses, required archives, preservation constraints, permits, and minimum viable aliquot sizes remain satisfied. Seal the reserve in an appropriate container or designate an untouched core interval; give it no initial assay owner; and record its quantity, preservation state, location, chain of custody, and retention limit. The allocation ledger labels it \"intentionally unassigned verification reserve,\" distinguishing it from missing, forgotten, unavailable, or surplus material. Routine allocation requests cannot consume it. Release requires a predefined trigger—such as discordant assays, a contamination alert, failed preparation, or an approved orthogonal verification question—and joint authorization. At the retention deadline, the responsible authority must renew, release, transfer, or dispose of it under the applicable rules rather than allowing indefinite ambiguous storage.","structural_mapping":[{"archetype_element":"Attention Competition Map","domain_realization":"A sample-allocation map shows how proposed assays, replicates, archives, preservation needs, and contingency demands compete for the same finite material."},{"archetype_element":"Omission Candidate","domain_realization":"Redundant, premature, or deferrable initial assays are candidates for removal or postponement when their allocation would eliminate a viable verification reserve."},{"archetype_element":"Protected Empty Space","domain_realization":"A physically sealed portion remains empty of assay commitments, treatments, and handling rather than being treated as unused capacity available for later schedule filling."},{"archetype_element":"Positive Form Relationship","domain_realization":"The uncommitted material supports interpretation of the completed assays by retaining the possibility of a matched retest directed by the uncertainty those assays reveal."},{"archetype_element":"Absence Boundary","domain_realization":"A sealed container or mapped core interval, barcode, inventory restriction, chain-of-custody rule, and retention deadline bound the reserve."},{"archetype_element":"Meaning-of-Absence Check","domain_realization":"The ledger distinguishes intentionally unassigned material from an allocation omission, unavailable sample, inventory error, legal hold, or preservation failure."},{"archetype_element":"Context Preservation Frame","domain_realization":"Collection metadata, handling history, preservation conditions, sample relationships, and all initial assay allocations remain linked to the reserve."},{"archetype_element":"Reintroduction Trigger","domain_realization":"Material enters an assay workflow only after a qualifying verification need, documented authorization, or an approved end-of-retention disposition."},{"archetype_element":"Accessibility and Recoverability Guardrail","domain_realization":"Authorized researchers can discover the reserve and request its release through a visible process;

Its absence is an intentionally unfilled assay commitment within a sealed sample partition, its intervention is sample-allocation and custody governance, and its causal path runs from total analytical consumption to loss of matched verification capacity, then from protected nonuse to uncertainty-directed reanalysis. It does not modify acoustic schedules, seafloor operations, data displays, or meeting behavior and can be adopted independently by a marine sample repository or expedition laboratory.","revision_record":{"parent_version":null,"progress_targets_addressed":["Generate one independently adoptable continuation candidate","Address a problem materially different from proposals 1 through 4","Use protected nonallocation as the active causal intervention","Provide complete operations, authority, safeguards, rivals, falsifiers, and bounded evidence"],"conceptual_changes":[],"operational_changes":[],"evidence_changes":[],"claim_changes":[]}}
