Tomorrow, Tested

Open research for the physical future. Ideas point towards the future. Experiments decide what gets there.

Claim boundary

Single-axis X rotation from rest and identity attitude; zero gyro bias, noise, and wheel scale error. Integer midpoint rigid-body plant with unclipped wheel momentum and momentum-limit safe mode. Independent floating-point RK4 quaternion replay uses the same applied torque, inertia, initial state, epoch, and step. Inertia sensitivity is a separate open-loop replay, not implementation disagreement. Watchdog latches safe mode after the second consecutive invalid sample and records expiration on the third. All physical maxima include the terminal state.

Hardware safety, flight readiness, flight qualification, certification, or real-spacecraft performance.
Unbounded stability, universal controller correctness, or validity outside the registered model and cohort.
Independent validation merely because owner-built instruments or baselines agree.

Revision 1: sha256:7284916be9b72873634c3e146c78ded672ada6be5af6a4b9285f3724bda47ae0. Retained unchanged; measurement interpretation superseded.
Revision 2: sha256:2f08a13a6b263be1b78737bc76bd8729c4e13a02870ac4ec6aa068453356b3db. Corrected single-axis measurement audit with matched-input quaternion replay.
