The opportunity is conditional on contamination being measurable, the target surviving the blind interval, and the approach outperforming fixed-delay processing and full-waveform modeling.","adopter_authorizer":"The instrument owner or principal investigator is the prospective adopter and may authorize a reversible timing-profile study; equipment-safety owners retain authority over interlocks and safety telemetry.","scores":{"meaningful_impact":{"score":3,"rationale":"False detections, missed weak responses, and biased decay estimates would materially impair the stated measurement objective if the contamination is present. The packet supplies no empirical magnitude, frequency, or demonstrated scientific impact, and the intervention can also erase fast dynamics."},"stakeholder_pull":{"score":2,"rationale":"Instrument owners, operators, and downstream analysts are identifiable beneficiaries, but the packet contains no expressed demand, adoption request, observed workflow burden, or evidence that the inferred problem is prevalent on a candidate instrument."},"incremental_advantage":{"score":3,"rationale":"A recovery-triggered holdoff could improve on continuous acquisition or a fixed short delay by excluding a bounded contaminated interval, while retaining more interpretability than unconstrained clipping. Advantage over calibrated full-waveform fitting is explicitly unresolved and depends on matched-sensitivity results."},"distinctiveness_plausibility":{"score":3,"rationale":"The proposal states a distinguishable incremental claim—measured recovery-triggered reintroduction with preserved gap metadata—against both a fixed-delay baseline and a waveform-model rival.

Apparatus-specific trigger stability and gating-induced transients remain material implementation uncertainties."},"adoption_authority_feasibility":{"score":4,"rationale":"The packet identifies an instrument owner or principal investigator who can approve a reversible pilot and preserves separate safety-owner control. Production adoption would still require calibration acceptance and coordination with analysts and safety owners."},"evidence_readiness":{"score":4,"rationale":"The candidate provides blank controls, blinded known-amplitude injections, comparator arms, outcomes, falsifiers, halt criteria, and rollback.

Benefit is conditional because improper gating could mask faults or create switching artifacts."},"scalability":{"score":2,"rationale":"The method may transfer conceptually across pulsed instruments, but thresholds, gating behavior, ring-down, detector settings, samples, and target lifetimes require apparatus-specific validation.
