Check 1 of the pilot review: the timing gap between groups A and B over time (run 2026-10-14 14:47 Halifax).
After the fact and exploratory: a description of the pilot's saved results, not a reading fixed in plan.md and not a new experiment. No model was run.
A toy model: structure inside the model, not evidence about cells. Histories, not memory: differences are between intervention histories and the states they leave.
Read: the pilot's 120 moment files (starts 103 to 114), each matching the hash in pilot_results.json. The gap reproduces the report's |A-B timing| at R (largest difference 1.6e-15 rad).
Gap: |psi_A - psi_B| in radians; 0 means the two groups' rhythms are in step, about 1.571 (pi/2) is what unrelated rhythms average. Split: half of (lowered gap minus raised gap); positive means the raised arm's groups sit closer in timing. Error bars and 'clear' (more than 3 bars) as in the report.

Limits
  Lower coherence makes each group's rhythm noisier, which pulls the average gap toward about 1.571. The lowered arm stays less coherent after R, so part of its wider gap can come from that. The matched push, at nearly the same coherence, is the comparison that separates timing from coherence level.
  Whether the gap carries the later-growth difference is not tested here; this only says whether it is still there when that difference appears.
