Paper 4 Research Closeout - 2026-05-03

Paid Vast training is paused indefinitely. The remaining Vast instance was destroyed on 2026-05-03 to stop storage billing. `vastai show instances` was empty immediately after destroying instance `35911134`. The recurring heartbeat monitor `monitor-nko-anchor-audit` was also deleted because the active remote audit no longer exists. - Path: `[home]/Desktop/nko-brain-scanner/local_results_cache/paper4_reproduction_35205256/results.json` - Script: `nko` - Mode: `trajectory` - TAR: `false` - TTT: `false` - LR: `0.0003` - Batch size: `32` - Dropout: `0.1` - Seed: `42` - Split: `232476 / 29060 / 29060` - Best validation loss: `0.6358872798606507` - Epochs trained: `47` - Test CER: `0.2057` This is the only locally retained result that directly supports the archived `20.57%` N'Ko trajectory anchor. The April 22 safe matrix is preserved locally, but it is not a strict validation of the 20.57 anchor because it used `lr=0.0001`, not `lr=0.0003`.
