Working Notes on the Operational Limits of Precision Measurement in Relativistic Experiments

These notes collect a series of essays examining the operational structure and interpretive limits of several foundational experiments in modern physics. The emphasis is on distinguishing measurement from inference and clarifying what experimental results strictly constrain. The primary content is provided as a self-contained HTML archive with internal navigation and rendering of equations via MathJax. These notes are exploratory and intended to facilitate careful study of operational definitions and measurement limitations. No alternative theoretical framework is proposed here. A brief PDF orientation is included for reference; it summarizes the table of contents and the structure of the archive. Future versions may expand and refine these working notes; this record represents v1.
