+# Adversarial Bug Report: fix-vram-model-prefix-match
+
+## Attack Vectors Tested
+1. **Empty model name**: Returns 0 (no match) — correct
+2. **Model name with only separator**: `:` or `-` alone — no match, correct
+3. **Case sensitivity**: `key.lower()` and `name_lower` handle case-insensitive matching correctly
+4. **Suffix that partially matches known suffix**: `instruct` vs `instructional` — `instructional` would not match since `split("-")[0]` gives `instructional` which is not in the set
+5. **Multiple separators**: `deepseek-r1:7b-instruct` — matches via `:` before reaching `-` check (correct, Ollama tag takes priority)
+
+## Findings
+No bugs found.
+
+## Verdict: PASS
