# IsSynth-Cars execution audit

- Audited: 2026-10-25T16:03:05.052404+00:00
- Run ID: `cars_issynth_20261025_seed0_support1`.
- Recovery state: **STOPPED_RECOVERABLE**. This new Molab runtime had no matching training process or local checkpoint before restore. Remote status was last synchronized after 32 completed epochs at step 1568. The user's epoch-33 batch-14 observation was uncheckpointed progress; epoch 33 must be recomputed from its boundary.
- The current full checkpoint, best checkpoint, 32 history entries, and 32 unique epoch CSV rows were recovered from the public model repository. Last CSV epoch is 31 (zero based), consistent with `next_epoch=32`.
- No final metrics existed remotely. Training must finish epochs 33–40, then test once using the best validation checkpoint and synchronize artifacts.
- Original and synthetic datasets are restored locally through the previously validated source archives and pinned manifests. No original images are published.

## Recovery action verified

- The source recovery helper was corrected to use a unique backup path when a prior snapshot backup already exists. The pinned SPC commit was restored without altering the frozen experiment configuration.
- Original data: 16,185/16,185 images, 196 classes, official train/test 8,144/8,041; source archive and per-image manifests matched. Synthetic data: 12,544 images, 64/class, archive checksum and CRC passed.
- DataLoaders returned the frozen 3,136 real support, 12,544 synthetic, 1,631 validation and 8,041 test samples; the checkpoint configuration signature matched. No new split or support selection was generated.
- The original supervisor resumed from `next_epoch=32`, `global_step=1568`. The runner wrote step 1569 in displayed epoch 33/40, establishing forward progress. One runner process is supervised; same-command child processes are DataLoader workers.
- Current classification: **ACTIVE_HEALTHY**. Dashboard cells are running and read restored historical metrics and plots. Final test remains pending and is configured to run automatically after epoch 40.

## Final result verification (2026-10-25T20:08:56.489603+00:00)

Training reached 40 epochs and 1,960 steps. The existing test predictions independently reproduce 7,506/8,041 = 93.3466% top-1 accuracy and macro-F1 0.932806. The public repository contains all 17 required artifacts; the best checkpoint SHA-256 matches the remote ETag. Current classification: **FULLY_COMPLETED**.
