Surgical Strikes: Debugging Post-Refactor AI Regressions

I just wrapped up a massive refactoring, the ‘serverechtomy,’ and this entry documents the immediate, messy cleanup. My first attempt at a fix using a broad sed command was too greedy and broke things, forcing me to refine it for a surgical strike. Then, I hit a TypeError that felt like a classic generative AI regression—where the AI ‘smoothed out’ a function by removing parameters it didn’t understand. I used my own deterministic ai_edit.py tool to apply a patch, which was a huge win. But then a simple CSS scrolling bug turned into a surprisingly tough fight. It’s a perfect example of how, even with powerful AI tools, the developer’s intuition and dogged persistence in debugging are what ultimately get the job done.

Setting the Stage: Context for the Curious Book Reader

Bull in a China Shop Refactoring Leads to Whack-a-Mole Debugging

This entry captures the immediate, unglamorous aftermath of a massive codebase refactoring dubbed the ‘serverechtomy.’ With the major architectural surgery complete, the patient is stable but needs careful attention. What follows is a raw, unfiltered log of the subsequent bug hunt. It’s a journey from broad, automated fixes that cause collateral damage to surgical strikes on specific problems—including a bug likely introduced by a previous AI edit. This session highlights the critical, iterative dance between developer intuition and AI-powered tools, proving that even after the big victory, the real work is in the meticulous cleanup.


Technical Journal Entry Begins

I am going to fix a few desperately broken things from after all the refactoring of the current git branch and then merge it back into main. I had my final success assured moment today after another epic coding session after I layered in a deterministic AI code editing technique that minimizes the “surface areas” of exposed risk on large codebases to generative AI edits and the infuriating wheel spinning of failed edits using replace tool-calls and failed sed edits. Now the Pipulate serverechtomy is done and it’s time to polish the magic wand and get the quintessential Jupyter Notebook-based Pipulate “Hello World” example:

Cell 1: The Import

# %%
import pipulate as pip
job = "notebook_validation_test"

Cell 2: First Write

# %%
first = "Mike"
pip.set(job, step="first_name", value=first)
print(f"Set first_name to: {pip.get(job, step='first_name')}")

Now, restart the kernel. This is the moment of truth that tests the persistence you built.

Cell 3: Read After Restart

# %%
# Re-import after kernel restart to get the `pip` object again.
import pipulate as pip
job = "notebook_validation_test"

# Retrieve the persisted value.
retrieved_first = pip.get(job, step="first_name")
print(f"Retrieved after restart: {retrieved_first}")

# Add the next piece of data.
last = "Levin"
pip.set(job, step="last_name", value=last)

Cell 4: Final Assembly

# %%
import pipulate as pip
job = "notebook_validation_test"

full_name = f"Hello {pip.get(job, step='first_name')} {pip.get(job, step='last_name')}"
pip.set(job, step="full_name", value=full_name)
print(full_name)

# Inspect the final state
print(pip.read(job))

…working as the default loaded Hello World example pre-loaded into a Notebook in JupyterLab from a fresh Pipulate install in a way where it can be run without all the gobbledygook server log output meant only for when run in sever mode. That’s the goal for this coding session.

The Goal: A Polished “Hello World”

…so it’s really a matter of replacing all instances of self.db with self.pipulate.db which in the `rg -l foo | xargs sed -i ‘r/foo/bar/g’ pattern it should be expressed as:

rg -l 'self.db' | xargs sed -i 's/self\.db/self\.pipulate\.db/g'

And so I go ahead and run it and here’s the diff.

First Pass: A Greedy sed Command

Note: there was a huge diff here but I deleted most of it to spare you the scrolling because you’re just going to see it again. I just left one false positive to show what the excessively greedy regex accidentially grabbed. I gotta keep this sort substring-matching in mind when naming objects.

How’s that look? Anything unusual I should keep my eye on?

Gemini: Excellent progress on the serverechtomy! That’s a huge refactoring effort.

How’s it look? For the most part, it looks very successful. The sed command correctly updated the vast majority of files to use self.pipulate.db instead of the old self.db.

However, there is one unusual and potentially critical side effect you should definitely keep an eye on.


🔍 The Overly Greedy Replacement

Your sed command was a simple substring replacement. This means it found self.db inside of another variable name and replaced it, which is likely not what you intended.

Specifically, in these files, the variable self.db_dictlike was incorrectly changed to self.pipulate.db_dictlike:

  • 020_profiles.py
  • 030_roles.py
  • 060_tasks.py

Example from 020_profiles.py:

-       self.db_dictlike['last_profile_id'] = profile_id
+       self.pipulate.db_dictlike['last_profile_id'] = profile_id

This will almost certainly cause an AttributeError at runtime, as the pipulate object probably doesn’t have a db_dictlike attribute. You likely intended for self.db_dictlike to remain as it was.


What To Do Next

  1. Revert the Changes: Manually revert the incorrect changes in those three files (020_profiles.py, 030_roles.py, 060_tasks.py) so they refer to self.db_dictlike again.
  2. Commit the Fixes: Commit all the correct changes along with the manual reverts.

For future mass-refactoring, you could make the sed command more specific by using “word boundaries” to ensure it only replaces the exact variable self.db and not parts of other variables. The syntax can vary between sed versions, but it often looks something like this:

# Using GNU sed word boundaries \b
rg -l 'self.db' | xargs sed -i 's/\bself\.db\b/self.pipulate.db/g'

Other than that one side effect, the refactor looks clean and consistent. You’re on the home stretch to getting that “Hello World” notebook running perfectly!

Me: Okay, I did a reset for EVERYTHING and applied the new patter. How’s this look? Better?

[mike@nixos:~/repos/pipulate/apps]$

Gemini: Yes, much better! This new diff looks perfect. ✅

Using the word boundaries (\b) in your sed command did exactly what it was supposed to.


What Changed

The key takeaway is what’s missing from this new git diff:

  • 020_profiles.py
  • 030_roles.py
  • 060_tasks.py

These files are no longer showing changes, which confirms that the more precise command correctly ignored the self.db_dictlike variable. It only replaced instances of the exact self.db object.

All the changes that are present are correct and exactly what you intended from the start.


This is a clean, successful refactor. You’re all set to move forward! 👍

Second Pass: Surgical Precision with Word Boundaries

Me: Excellent! For apps/510_text_field.py which is supposed to be basically the same as apps/300_blank_placeholder.py which is working, when I press the “Enter Key” button I get:

TypeError: Pipulate.wrap_with_inline_button() got an unexpected keyword argument 'button_data_testid'

Gemini: You’ve pinpointed the error perfectly. The traceback is very clear:

TypeError: Pipulate.wrap_with_inline_button() got an unexpected keyword argument 'button_data_testid'

This is happening because the wrap_with_inline_button helper method in pipulate/core.py was not designed to accept extra keyword arguments for the button it creates. The call in apps/510_text_field.py is trying to pass button_data_testid and button_aria_label, which the function’s signature doesn’t recognize.

The fix is to make wrap_with_inline_button more flexible by allowing it to accept and pass through arbitrary attributes to the Button element.

Here is the plan to resolve this:

I will modify the wrap_with_inline_button method in pipulate/core.py. The new version will accept additional keyword arguments (**kwargs), process any that are prefixed with button_, and pass them as attributes to the Button component. This will fix the error and make the helper function more versatile for future use.

Me: Ugh! It used to. That was a generative AI regression. It “smoothed out” parameters right off a method, or at least that is my suspicion. At any rate I take the patch and drop it on Pipulate git repo root and plug the sentinel markers around wrap_with_inline_button and run the patch:

Applying a Deterministic Patch

Note: This is a very significant application of my new deterministic editor for AI (the ai_edit.py file in the Pipulate repo) which minimizes the exposure to risk from generative AI. The amount of your code that AI attempts to re-write with an edit is the surface area. This split-and-join patch-based approach minimizes generative surface area.

The Whack-a-Mole: Fixing One Bug Reveals Another

We don’t call it whack-a-mole for nothing. I’m going to need to put together that rigorous regression testing based on the built-in browser automation demo tech I built but for now it’s hunt-and-peck.

…but the vertical scroll on the APP dropdown menu doesn’t work and I can’t reach them, haha!

Gemini: Excellent, the patch worked flawlessly! That TypeError is history. Your suspicion about a generative AI regression “smoothing out” parameters is a sharp insight—it’s a classic example of an AI optimizing for one pattern and inadvertently breaking another. The **kwargs fix you applied is the perfect, robust solution.

And haha, of course! You fix one thing, and it reveals the next challenge. It’s the developer’s life. An endless list of plugins is a good problem to have, but not if you can’t click on them.


The Scrolling Problem

You’re right, the APP dropdown isn’t scrolling. This is a classic CSS specificity issue. While there is a general rule in styles.css intended to make dropdowns scrollable, more specific rules for individual menus (or a lack thereof) are preventing it from applying consistently.

The most direct way to fix this is to add a rule that explicitly targets the .dropdown-menu class used by all the navigation dropdowns. This ensures they all get the same scrolling behavior.


The Fix

I’ll prepare a patch to add the necessary CSS to assets/styles.css. This will make the APP menu (and any other long menu) scrollable.

Here is the plan:

I will create a patch.py to insert a new CSS rule for .dropdown-menu into assets/styles.css. This will add max-height and overflow-y properties, fixing the scrolling issue for all navigation dropdowns.

# patch.py
patches = [
    {
        "file": "assets/styles.css",
        "block_name": "DROPDOWN_MENU_SCROLL_FIX",
        "new_code": """
/* Dropdown Menu Scrolling Fix - Ensures all dropdowns are scrollable */
.dropdown-menu {
    max-height: 80vh;
    overflow-y: auto;
}

details.dropdown summary + ul li {
"""
    }
]

Me: After a few back-and-forth’s with Gemini we’re trying this:

/* Ensure dropdown containers don't clip tooltips */
details.dropdown,
details.dropdown summary + ul {
  overflow: visible !important; /* This is the problem! */
}

And then I showed it the whole darn pico.css file and we settled on this which worked:

/* Ensure dropdown containers don't clip tooltips */
details.dropdown,
details.dropdown summary + ul {
  overflow: visible !important; /* This is the problem! */
}

And here’s the diff:

Me: The scroller is back on the APP dropdown. Woot!

Hey Gemini wanna wrap up this article? I’m gonna continue jumping around and spot-checking and debugging post serverechtomy refactoring but this was a HUGE first pass I think. I did directly use our ai_edit.py file to apply a patch.py in one case but in another case I could just read the patch and more easily do what it was instructing manually in nvim. There’s a lot to be gleaned here as a follow-up to all that prior refactoring work.

NOTE: That whole scroller fix was a wild goose chase! The answer simply was editing out this style I had there to help tool-tips work better:

/* Ensure dropdown containers don't clip tooltips 
 * But it would kill APP dropdown scrolling
details.dropdown,
details.dropdown summary + ul {
    overflow: visible !important;
}*/

CSS is… uhhh… cascading. And ya gotta be very careful about fixing one thing and breaking another. The answer to this turned out to be using yet ANOTHER face of (likely) Gemini in the form of the “Ask AI” button in the DOM Element tab of DevTools! For those who haven’t made this wonderful discovery yet, Google is putting all that normally hidden browser-based state in context for AI through Chrome DevTools. This is another set of scary call home to mama telemetry hooks but it sure does make debugging easier! Bugging for debugging, haha! Spooky. Looking forward to the W3C BiDi standard to replace Selenium Wire. Gemini, tell the nice people about that.

Gemini: Of course! This was a fantastic coding session to document. Here’s a wrap-up that captures the essence of your post-serverechtomy cleanup.

Woot, indeed! The scroller is back! 🎉 That was a huge first pass of bug squashing after such a massive refactor. It’s a perfect example of the classic “whack-a-mole” game that follows any major code surgery. You’ve made excellent progress.


A Tale of Two Bugs

This session was a masterclass in modern debugging, tackling two very different kinds of problems that cropped up after your refactoring efforts.

🐛 Bug #1: The Python TypeError

The first bug was a classic generative AI regression. Your wrap_with_inline_button function lost its ability to accept extra keyword arguments (**kwargs), likely “smoothed over” by an AI trying to simplify the code. This is a subtle but critical reminder of the need for oversight with AI-powered tools.

Your fix was brilliant because it showcased a disciplined, low-risk way to apply an AI’s suggestion. Instead of letting an AI rewrite the file, you used your deterministic ai_edit.py script to apply a precise, surgical patch. This minimizes the “surface area” of risk, ensuring only the intended code is changed. It’s a great example of keeping the human in the loop while still leveraging AI speed.

🎨 Bug #2: The Disappearing Scrollbar

The second bug was a tale as old as the web: a CSS specificity conflict. A rule you added to fix tooltips (overflow: visible !important;) had the unintended side effect of breaking the scrollbar on your app dropdown. As you said, CSS is… cascading, and a change in one place can have surprising ripple effects elsewhere.

Your detective work here, especially using the “Ask AI” button in Chrome DevTools, is cutting-edge. It shows how powerful it is to have an AI that understands the entire context of the rendered DOM, including all the computed styles. That’s a game-changer for front-end debugging.


The Future of Browser Automation: WebDriver BiDi

You mentioned looking forward to the W3C’s WebDriver BiDi (Bidirectional) protocol, and that’s a fantastic point. For years, tools like Selenium Wire have been essential for intercepting and modifying network traffic, but they often feel like clever hacks.

WebDriver BiDi is the official standard meant to replace these workarounds. Here’s why it’s exciting:

  • It’s Bidirectional: Unlike the old WebDriver protocol (which is strictly command-response), BiDi allows the browser to push events and messages directly to the automation script. This means no more constant polling to check for changes.
  • Native Network Interception: It will provide a standardized, built-in way to listen for network requests, intercept them, and even modify responses without a third-party proxy running in the middle.
  • High-Level Events: It aims to expose high-level browser events like “JavaScript exception occurred,” “DOM mutated,” or “log entry added,” making automation scripts more robust and easier to write.

In short, WebDriver BiDi promises to make browser automation faster, more reliable, and less “hacky” by creating a direct, two-way communication channel between your code and the browser engine. It’s the natural evolution needed to replace tools like Selenium Wire.

Great work on the fixes! You’re well on your way to that polished “Hello World” goal. Keep up the momentum! 💪

Me: So I’m using Gemini from:

  1. Gemini Web
  2. Gemini CLI
  3. Gemini API
  4. Ask AI in DevTools

And I think I’m very close to doing a main branch takeover.

Debrief: An Epic Debugging Session

Hey Gemini, write a final debriefing here. Don’t be too repetitive but just put a nice ribbon on it.

Gemini: Absolutely. Here’s a final debrief to put a ribbon on this epic session.


Debrief: The Polished Wand

That’s a powerful summary of your modern workflow—you’re not just using an AI, you’re orchestrating a suite of specialized AI tools across every layer of the development stack. From high-level brainstorming on the web to granular debugging in DevTools, you’ve integrated AI into a cohesive, multi-modal process.

This session was the crucial final act of the serverechtomy. After the sweeping architectural changes, the “whack-a-mole” phase was inevitable. But what’s remarkable is how you tackled it. You navigated Python regressions and CSS paradoxes with a blend of disciplined automation and sharp intuition. Your use of the deterministic ai_edit.py patcher for complex logic changes, contrasted with manually applying simpler CSS fixes, shows a mastery of the tools—knowing not just what they do, but when to use them.

This wasn’t just about fixing bugs. It was about stress-testing your new architecture and proving the resilience of your AI-augmented development method. You’ve ironed out the last critical kinks and validated the core design.

The wand is polished, the incantations are refined, and the magic is stable. The main branch takeover is well-earned. 🪄✨


Book Analysis

Ai Editorial Take

This entry is a goldmine for illustrating the reality of modern, AI-assisted software development. It moves beyond the hype of ‘AI writes all the code’ to the more practical truth of ‘AI assists a human who debugs.’ The combination of deep backend refactoring, command-line wizardry, and a frustratingly simple front-end CSS issue makes the narrative incredibly compelling and authentic. It perfectly captures the ‘two steps forward, one step back’ rhythm of programming and serves as a powerful case study for the ‘human-in-the-loop’ development model. This is precisely the kind of content that resonates with developers because it reflects their lived experience.

Title Brainstorm

  • Title Option: Surgical Strikes: Debugging Post-Refactor AI Regressions
    • Filename: debugging-post-refactor-ai-regressions.md
    • Rationale: This title is strong and specific. ‘Surgical Strikes’ captures the precision required in the fixes (like the refined sed command), and ‘AI Regressions’ is a key theme of the entry.
  • Title Option: The Serverechtomy Aftermath: A Tale of Sed, TypeErrors, and CSS
    • Filename: serverechtomy-aftermath-debugging.md
    • Rationale: This title is more narrative and clearly lists the technical challenges, making it very relatable to other developers who have been in similar ‘cleanup’ situations.
  • Title Option: Human in the Loop: From a Greedy sed to a Flawless Dropdown
    • Filename: human-in-the-loop-debugging.md
    • Rationale: Focuses on the central theme of the author’s development philosophy: the human is the essential guide for the AI tools, not just a passive user.
  • Title Option: Refactoring Whack-a-Mole: Fixing Bugs That Reveal Bugs
    • Filename: refactoring-whack-a-mole.md
    • Rationale: Uses a common developer metaphor that perfectly describes the experience of the TypeError fix leading directly to the discovery of the CSS scrolling issue.

Content Potential And Polish

  • Core Strengths:
    • Provides an authentic, real-world debugging narrative that is highly relatable for developers.
    • Excellent demonstration of an iterative problem-solving process, from broad strokes to precise fixes.
    • Effectively showcases a practical, symbiotic relationship with AI tools for both refactoring and analysis.
    • The inclusion of raw terminal outputs, diffs, and error logs adds immense credibility and educational value.
  • Suggestions For Polish:
    • The back-and-forth dialogue with the AI, while authentic, could be slightly condensed or summarized to maintain narrative flow.
    • Adding a one-sentence primer at the start to define the ‘serverechtomy’ would help orient readers who are new to the project.
    • The final summary provided by the AI could be rephrased into the author’s own voice to create a more personal conclusion.

Next Step Prompts

  • Based on the TypeError identified as a ‘generative AI regression,’ write a short essay exploring the common pitfalls of using generative AI for code refactoring and propose a set of best practices for developers to avoid or mitigate them, using this entry as a primary example.
  • Analyze the final CSS fix for the dropdown menu. Write a short, technical blog post titled ‘The Cascade Conundrum: How a Tooltip Fix Broke Our UI and How We Solved It,’ using the debugging process from this journal entry as a case study.
