Much of each trace consists of predictable open-pore current, slow baseline movement, and characterized electronic noise, while decision-relevant particle passages appear as comparatively sparse blockade waveforms. Transporting and processing every complete sample through a shared acquisition path can exhaust its bandwidth or channel capacity; simple downsampling or fixed event thresholds can instead remove low-amplitude, overlapping, or atypically shaped passages.","actors":["Nanopore assay scientist","Nanopore-chip operator","Readout-electronics engineer","Signal-model owner","Scientific data steward"],"observable_state":"For each pore, the system observes timestamped ionic current, applied voltage, amplifier range, sampling state, electrolyte temperature and conductivity, pore identity, calibration age, packet sequence, and hardware-health flags. A scoped predictor produces the expected open-pore waveform and uncertainty; the signed difference between that prediction and the measured current preserves unexplained blockade shape, direction, duration, and cross-pore context.","consequence":"Predictable baseline samples consume shared digitization, transport, storage, and analysis capacity, potentially limiting the number of pores that can be observed at the required fidelity or encouraging lossy preprocessing that obscures scientifically relevant translocation evidence.","affected_objective":"Use bounded acquisition and analysis capacity to preserve reconstructable particle-translocation evidence across the nanopore array while maintaining independent raw audits, explicit missingness, hardware safeguards, and scientist control over assay interpretation.","intervention":"For one nanopore-chip design, electrolyte condition, voltage range, and assay class, run a versioned predictor beside each eligible pore channel and a compatible predictor at the reconstruction service. Predict the next open-pore current from recent reconstructed state and declared operating context, then encode the signed measured-minus-predicted residual with pore, time, uncertainty, sequence, and model metadata. A precision-and-consequence gate allocates the shared channel to residuals based on source quality, residual structure, event consequence, reconstruction loss, and channel cost rather than amplitude alone. Qualifying residuals trigger transmission of a complete pre-event and post-event waveform from a local raw ring buffer. Random and risk-stratified full windows travel through an independent audit path, and scheduled full-state anchors resynchronize predictor state. Amplifier saturation, pore-current collapse, leakage, temperature excursions, packet loss, stale calibration, model mismatch, structured drift, and exhausted reconstruction budgets force complete-waveform fallback. Baseline updates occur slowly and freeze around candidate events; only reviewed evidence may authorize a new deployed model version.","structural_mapping":[{"archetype_element":"Prediction target and

This proposal instead addresses multichannel electrical acquisition capacity in solid-state nanopore assays by predicting each pore's temporal open-current waveform and coding particle-translocation residuals, with buffered full-event retrieval. It does not inspect fabricated geometry, use a layout model, or govern wafer disposition. Proposal 2 addresses self-generated actuator response during scanning-probe manipulation through efference-copy cancellation and routes unexplained force or deflection to a low-latency probe-protection supervisor. This proposal has no outgoing motion command or self-sensory cancellation path: its prediction is a stochastic per-pore baseline, its residual represents possible passages through a stationary nanoscale aperture, and its downstream objective is reconstructable parallel assay readout rather than physical trajectory safety. It uses different actors, instruments, observations, constrained resources, actions, failure conditions, and evidence, and can be adopted independently of both earlier proposals.","revision_record":{"parent_version":null,"progress_targets_addressed":["Initial complete proposal at index 3","Material differentiation from sealed proposals 1 and 2","Causal fidelity to predictive residual processing","Operational authority, safeguards, falsifiers, and bounded evidence"],"conceptual_changes":[],"operational_changes":[],"evidence_changes":[],"claim_changes":[]}}
