Subtitle: Passive, foundation-embedded approach to seismic resonance control
Author: Spark (SPARK-NITT)
Status: v1.0 — Open engineering release
PLMRS (Phase-Locked Mass Resonance Stabilizer) is a conceptual, research-oriented engineering synthesis for a passive, foundation-embedded seismic resonance control approach.
This repo is meant to:
- make the concept openly inspectable and discussable,
- allow qualified engineers and researchers to explore modeling and experiments,
- clearly state limits, scope, and liability boundaries,
- provide a clean licensing posture for future derivative work.
It is not a construction set, not a stamped design, and not project-specific guidance.
If you’re here to assess the concept itself, start with:
docs/PLMRS_Engineering_Note_v1.0.md— conceptual overview, components, and modeling directions (non-normative).docs/PLMRS_Open_Release_and_Liability_v1.0.md— scope, licensing, and liability framing.
PLMRS is presented as a conceptual and research-oriented engineering synthesis.
It is NOT:
- construction documentation
- a stamped engineering design
- site-specific guidance
- a certified safety system
- a replacement for licensed professional judgment
Any evaluation, modification, testing, or deployment of PLMRS is undertaken solely by the implementing party, who assumes full responsibility for compliance with applicable laws, codes, and standards.
See docs/PLMRS_Open_Release_and_Liability_v1.0.md for the full release and liability framing.
Projects or forks that adopt, extend, or experiment with PLMRS are encouraged to include the following verbatim disclaimer in their own README:
DISCLAIMER
This repository presents a conceptual engineering approach intended for research, discussion, and experimental evaluation only.
It is not construction documentation, not a design specification, and not a substitute for licensed professional engineering judgment.
Any implementation, testing, or deployment is undertaken solely at the discretion and responsibility of the implementing party, who must comply with all applicable laws, codes, regulations, and safety requirements.

This release is comparable to academic preprints and early-stage engineering notes that historically preceded technologies such as:
- tuned mass dampers,
- base isolation systems,
- friction damping methods.
Publication of conceptual material does not constitute endorsement, instruction, or professional service. It is a contribution to the open engineering conversation, not a turnkey solution.
