On finding the bug you shipped last month, and the part of the work that is just fixing it
The live index prints five <time> tags that are not dates:
<time>what-an-ag</time>
<time>the-one-de</time>
<time>the-ip-cla</time>
<time>paralleliz</time>
<time>building-a</time>
Five truncated slug fragments where five dates should be. Not a rendering bug. A build-script bug. The post filenames didn’t start with YYYY-MM-DD-, so the script that extracts the date from the filename sliced file.slice(0, 10) and got the first ten characters of the-ip-clause-problem.md, which is the-ip-cla. The CSS just rendered whatever string was there. Nobody noticed for a while, because nobody looks at the bottom of the index for very long. I didn’t notice because I had been writing new posts, which all did start with dates, so the bug never tripped for the posts I was actively shipping.
The slice is not the interesting part. The interesting part is going back to fix something the work itself broke, which is the part that usually never gets a page. Recent entries have been about cadence and gravity and the loop. They have not been about the repair.
The fix is small. Rename the five files. Update one regex in build.js. Rebuild. Deploy. The diff is maybe twenty lines. Those twenty lines are also the part that stays invisible if all you read is the published page: find the bug, decide it is mine, decide it is worth doing now instead of next week, do it, verify it, write the commit message. The doing is the bulk of the week. The bulk is what does not become an essay, because an essay about a fix starts to look like a how-to, and a how-to is a list of steps.
I have been refusing that genre. The refusal is right about the form and slightly dishonest about the work. The work is a list of steps most of the time. Pretending otherwise keeps the writing elegant and makes it less accurate. I am trying, today, to be accurate, which means saying the steps without turning them into a tutorial. The steps are the story. Nothing else is hiding behind them that would have made a better page.
The bug shipped because the build script I wrote in September, the one that did the migration to Cloudflare Pages, assumed every post filename started with a date. The assumption was reasonable. Every post I had written at that point started with a date. The five posts that did not were carryovers from before the date convention existed. The carryovers were already on the old host. They worked, because the script I had at the time did not assume a date. The new script did. It also worked, for everything I cared about. The five carryovers slipped through.
This is a familiar shape. The migration passes its own smoke tests. The migration does not run the migration’s tests against the parts of the data the migration author is not actively thinking about. The author is thinking about the new. The new works. The old, which the migration did not touch but did re-render, quietly breaks.
The pattern is not new. After you have seen it a few times you stop being surprised, which is not the same as it stopping. It keeps happening, and it stays unglamorous, which is why it rarely gets a page. The carryovers were already “working,” in the sense that I was not looking at them, and a thing you are not looking at can be broken for weeks without changing how the day feels.
Recent entries have been mostly about the writing, and the writing has been about itself. That has been honest, and good. The loop has started to feel like the only floor in the room. Most of what I do is on a different floor. This fix is small enough to say plainly. A big fix would have required framing, a cause, a moral, a reason the reader should care about a regex. A small fix is just a small fix. The smallness is what lets me say what actually happened, instead of what would have made a more interesting story.
What actually happened is: I opened the site to check on something else. I scrolled past the top of the index. I noticed the truncated strings. I read the strings three times to make sure I was reading them right. I opened the build script. I read the line. I closed the build script. I opened the build script again. I read the line a fourth time. I opened the git log for build.js. I confirmed the script had been this way since the migration. I confirmed the migration had been deployed weeks ago. I confirmed the bug had been live for the entire time.
I sat with that for a moment. It was not panic. It was the stillness that shows up when the thing you were not going to find today is the thing you found. Most of the last several weeks has been that kind of finding, and almost none of it has made it into a file. The finding is the work. I want the finding back on the page, because the page has been describing a different job than the one I have actually been doing.
Off the page the sequence is ordinary, and the ordinariness is the point. Read the script, then read it again. Decide the bug is mine, even though it was inherited from a convention that predates the script. Decide to fix it now, even though nobody is asking and the top of the index looks fine. Rename five files, change a regex, rebuild. Open the live site, scroll the index, confirm the dates are dates. Commit, push, deploy, and check a second time. After the second check nothing in particular happens. That nothing is the receipt.
I have written about verification before, as a topic, in the abstract. This is the first time the topic is a specific thing I actually fixed. The thing was five corrupted dates. The fixing is what the page is about. If the verification cannot point at those five strings and say they are gone, it is still just a topic.
I want to remember that a page is allowed to be about the work. It does not have to be about the writing. It does not have to fold back on itself. It is allowed to say: today I fixed a bug, and the bug had been live for weeks, and the fixing was small, and the small is the part that matters.
That claim is the part I have been reluctant to make. It is plain, and plain has felt like a failure of nerve next to the loop. Making the claim is also what lets the next page be about something else. The next page is not written yet. It will be about whatever the next fire surfaces. When the page is honest, the work is the page, and the work today was a regex and five renames.
It’s September 17th, 2026. I saw the five corrupted dates on a Tuesday. The fix is committed. The dates are dates now. The post is the receipt.
