v2.1.0: measurement engine, sessions, lessons and more

Ten upgrades since 2.0.0. Full details are in CHANGELOG.md.

• Measurement engine: sweeps are fitted with a Lorentzian dip, so resonance, Q and their uncertainties are measured instead of fixed placeholders; per-position repeatability statistics.
• Durable sessions and run library: autosave, resume after reload, 50,000-record ledger.
• Reproducibility bundles and validated import: checksummed .sphere.json bundles, CSV import with column mapping.
• Run comparison with per-position differences and condition diffs.
• Spatial field model with real coverage, next-point suggestions and "Run these points".
• Accessibility and mobile: an axe audit of all pages, fixed; dialogs, announcements, colour-vision-safe palettes.
• Deep links, embed mode and offline support.
• Dr. Wire run review by phone, offline and read-only.
• Live Timeline with scrub-back and CSV export.
• Learning Paths: eight graded lessons and a classroom report.

SPHERE Virtual Lab (SPHEREVL) & Control Room v2.0.0 — Protocol LOC-1 Metrology Simulator

SPHERE Virtual Lab (SPHEREVL) — Control Room v2.0.0

Official archival release of the SPHERE Virtual Lab (SPHEREVL) / Control Room v2 interactive 3D metrology and telemetry simulator for Project S.P.H.E.R.E. (SPHERE Research, LLC).

Highlights & Capabilities

• 3D Acoustic & Optical Readout Simulation: Models non-contact Laser Doppler Vibrometry (LDV) and Vector Network Analyzer (VNA) swept-sine characterization above 230 kHz in a precision hollow copper sphere under Protocol LOC-1.
• Common-Mode Drift & Reference Chain: Simulates Rubidium (Rb) atomic frequency standard synchronization, matched reference artifact tracking, and multi-sensor environmental telemetry (barometric, thermal RTD, triaxial vibration).
• Falsifiability & Bounded Nulls: Incorporates Two One-Sided Tests (TOST) equivalence evaluation criteria.
