Retained and revised analysis code for boundary-dependent characterization of a fingertip-worn ERM actuator module

This code-only software release supports the manuscript “Boundary-dependent command–output characterization of a fingertip-worn ERM vibrotactile actuator module with perceptual validation.” Version 1.1.0 retains the previously deposited Arduino/Python source-lineage and primary analysis files and adds the revision scripts for JND replay and update/reversal sensitivity, archived RMS segmentation/aggregation sensitivity, and spectral-peak summary sensitivity. Documented release companions provide FWP–ADT comparisons, physical group-summary checks and acquisition-block plotting. The package includes empty input schemas, synthetic software tests, provenance, dependencies and file hashes.

No empirical human or non-human datasets are distributed in this code record. Human-subject raw data, participant-linked values, trial records, demographic metadata, session identifiers, timestamps, photographs, figure-source workbooks and internal analysis outputs are excluded. Selected outcomes are reported in the article and Supplementary Information. Reproducing empirical results requires the corresponding authorized local inputs; the public synthetic tests do not reproduce study observations.

The exact historical 21-stage acquisition-source snapshot was not preserved. The retained GUI belongs to a later source lineage; the 21-stage mapping file is reference documentation, not a recovered historical executable. Release companions are distinguished from original analysis scripts in CODE_PROVENANCE.md. The custom scholarly-inspection terms in LICENSE.txt are unchanged. Files remain restricted during peer review and are intended to become publicly accessible no later than publication of the associated article.
