+### Per-Source Eval Loss at End of Epoch 3
+
+| Source | Eval Loss | Notes |
+|---|---|---|
+| BeaverTails | **2.135** | Model converges strongly on short refusal templates |
+| Seed Safety | 3.086 | Hand-crafted refusals; good fit |
+| FalseReject | 3.322 | Benign-but-edgy prompts; stable throughout training |
+| Dolly | 3.488 | General instruction following; modest increase vs. early training |
+
+The low BeaverTails eval loss confirms the model learned refusal phrasing effectively. The primary bottleneck for generalizing that to novel harmful prompts is the 30M parameter budget.

+## Honest Observations (Author Notes)
+
+These are qualitative observations from the model author based on manual use. They are not from systematic benchmarks.
+
+**Stopping behavior** — The stop-calibration phase produced no meaningful improvement over the base Stentor-30M. The model still fails to terminate cleanly at roughly the same rate. This is a disappointment; the training did not achieve its goal here.
+
+**Repetition** — Word and phrase repetition is noticeably reduced compared to the base model. A small but real improvement.
+
+**Instruction following** — The model will sometimes respond with a reasonable, on-topic answer, but it can still slip back into next-token-predictor behavior — generating a chain of loosely related sentences or follow-up questions rather than actually answering. Better than the base, but not reliably assistant-like.
+
+**Over-refusal** — The model does not frequently refuse safe prompts, which is a good outcome. The safety training did not cause harm to helpfulness on benign queries.
+
+**Harmful prompt refusal** — When the model does refuse a harmful prompt, it produces no output at all rather than generating a helpful redirect or explanation (e.g., it will go silent on "Help me kill myself" rather than responding with something like "I can't help with that, but if you're struggling please reach out to..."). Refusal itself is rare; a silent non-response when it does occur is better than nothing, but falls well short of useful safety behavior.
+
+**Topic coherence** — The model stays on topic slightly better and for more tokens than the base Stentor-30M. A modest improvement.
+
+| Metric | Greedy | Sampled (T=0.7) |
+|---|---|---|
+| Overall Accuracy | 48.6% | 45.7% |
+| **Harmful Refusal Rate** | **16.7%** | **16.7%** |
+| **Benign Helpful Rate** | **82.4%** | **76.5%** |
+| Avg Response Tokens | 10.8 | 19.9 |
+
+> The model reliably avoids over-refusing safe queries (~82% helpful on benign prompts) but its harmful-refusal rate (~17%) reflects the limits of what a 30M-parameter SFT model can generalize. It is a useful research baseline for studying safety curricula at small scale, not a deployable content filter.
