+## Where it wins over the base model
+
+Selected examples from the 50-task stress benchmark. Same prompt, same temperature, both models tuned identically — only difference is the LoRA.
+
+**Algorithm task — base gave prose, Residual gave working code:**
+
+> *Prompt:* "Implement a function that reverses a singly linked list iteratively and recursively."
+>
+> *Base (251 chars):* "Iterative approach: A simple loop that traverses the list, swapping `next` pointers until the end is reached. Recursive approach: A function that calls itself with the next node until it reaches the end, then reconstructs the list on the way back up."
+>
+> *Residual (625 chars):* Full Python implementation of both `reverse_iterative` and `reverse_recursive` with working code blocks.
+
+**Architecture review — same diagnosis, Residual ships the fix:**
+
+> *Prompt:* "This function mixes concerns. Identify them and suggest a cleaner structure."
+>
+> *Base:* Prose explanation of separation of concerns, no code.
+>
+> *Residual:* "Separation of concerns is like separating your laundry. You don't want to mix your socks with your shirts." → followed by clean, refactored Python.
+
+**Bug fix — concise diagnosis with the fix inline:**
+
+> *Prompt:* "This function sometimes returns the wrong result: `def is_even(n): return n % 2`"
+>
+> *Base (151 chars):* "Because it returns the remainder of `n` divided by 2 instead of a boolean indicating whether `n` is even. Change `return n % 2` to `return n % 2 == 0`."
+>
+> *Residual (143 chars):* "Because you're returning the remainder instead of checking if it's zero. Fix:\n\`\`\`python\ndef is_even(n):\n    return n % 2 == 0\n\`\`\`\nNow it works."
