How this log works: Each row is one test. Rows with blank Outcome and Compliance fields have not yet been run. Predictions are documented before any data collection begins. Results, delta, and lessons learned are filled in after a test is completed. This log is the program's internal record. Externally confirmed predictions are also logged on the main Results Registry.

ID	Test Name	Type	Prediction	Doc. Date	Run Date	Outcome	Control	Compliance	N Tests	Delta	Next Steps	Lessons Learned	Notes
CYM-001	Phase 1: Ground-Based Prototype Validation	Internal / Lab	A transparent sphere with a tetrahedral transducer array and particle medium under gravity will show the particle medium settling onto surfaces as expected under gravity, confirming the instrumentation is functioning correctly and establishing the baseline that microgravity will disrupt.	February 2026	Not yet	Not yet	Single-transducer excitation as control for multi-transducer patterns. Frequency sweep across about 400 Hz to 4 kHz to measure the chamber's resonances before Phase 2. Density-matched beads test the shell predictions on the ground.	Pending	Not yet run. Phase 1 design under review.	Not yet	Finalize instrumentation specification. Source transparent sphere and particle medium. Note: Phase 1 methodology is preliminary and open to improvement before prototyping begins. Contributions from acoustic engineers welcome.	Not yet	The methodology for this phase is explicitly marked preliminary. See program page for details.
CYM-002	Phase 2: Parabolic Flight Microgravity Acoustic Fields	Internal / Lab	In microgravity (about 22 seconds per arc, 30 to 35 arcs), particles in the driven sphere will gather in three-dimensional patterns set by its resonances: one particle shell at the first radial mode (ka = 4.493), with a radius that depends on the medium; nested shells at the next radial modes (ka = 7.725 and 10.904), which are not harmonics; and four, twelve and twenty-four clusters near the shell mode and at the l = 3 and l = 4 resonances. Predictions revised in preprint version 1.1 (10.5281/zenodo.22768860), September 2026.	February 2026	Not yet	Not yet	Phase 1 ground-based patterns as baseline. Observed node positions compared with positions calculated from the acoustic wave equation for the same chamber and frequencies.	Pending	Not yet run. Requires Phase 1 completion and funding for parabolic flight.	Not yet	Complete Phase 1. Secure parabolic flight funding (estimated $50,000 to $150,000). Design flight payload. Pre-register predicted geometries before any flight data is collected.	Not yet	All Phase 2 predictions will be pre-registered on Zenodo before any data collection begins. This is a firm commitment.
CYM-003	Retired: Crop Formation Geometry Correspondence	Thought Experiment / Combination	3D cymatic patterns in microgravity, when cross-sectioned along a horizontal plane, will produce geometries corresponding to documented crop formation patterns. This prediction is logged independently of the physics experiment and evaluated separately.	February 2026	Not yet	Not yet	Blind comparison: analyst who has not seen the crop formation database evaluates whether cross-sections match documented patterns above chance level.	Retired	Retired September 2026. Will not be tested.	Not yet	The prediction assumed that Chladni figures are cross-sections of a three-dimensional field. They map the vibration of a flat plate, so the comparison had no physical basis.	Not yet	Kept here as a record of the retired prediction. It is no longer listed on the Testing Schedule or in the test registry.
