Was trying to update sqlite version for Turso and add more tests, and somehow ended up finding 3 optimizer bugs in SQLite. Wasn’t expecting that, but hey, I’ll take it.

Folks here might be interested in this , it was presented today morning in sigmod

"There is no magical checkmark for software correctness."

At Bug Bash 2026, @bugarela made the case for chasing confidence instead, and showed why the AI era raises the stakes.

Here's a breakdown 🧵

Sounds like on hell of a bug

This is an astoundingly rapid change in something so basic. In 15 years the proportion of people who say college is very important has decreased by more than half.

Turns out I don't need to reharse a whole ass conversation in my mind

[Pavan-Nambi @pavan4820]

Few things i realised on day 2 of sigmod

- Quite a lot of ppl don't know turso.
- tech database twitter is smaller and a bubble
- most people are as nervous as u, all u need to do is say your name and convo happens naturally.
- need glasses lol cant see anything clearly

Outputs that sound right are not the same as outputs we can prove right.
The next phase of AI runs on verified systems: formal methods, theorem provers, runtime checks, provable agents.

It's time to verify AI !

@Hixon101 @glcst @quint_lang Hi, you can find the initial version here - https://t.co/hArvj7C8jt - it was messy tho

[Quint @quint_lang]

One of the most valuable things about Quint is not just that it finds bugs, it exposes behaviors engineers often don’t think to test.

The Turso team used Quint to model SQLite’s C API contracts, automatically generate traces, and replay them against the real implementation.

The result: 10+ bugs uncovered in SQLite while hardening Turso.
What’s especially compelling is the kind of behavior Quint explored systematically:

→ unexpected API call sequences
→ subtle state transitions
→ edge-case interactions
→ assumptions hidden inside implementation details

Instead of relying only on humans to imagine “what could go wrong?”, Quint explored the state space automatically and generated concrete counterexamples when contracts were violated.

Huge kudos to @Pavan4820, @Glcst, and the @tursodatabase team for the fantastic work.

I chatted with @duswnchl, based in South Korea, who works at the open-source consultancy, and worker-owned cooperative, @igalia. We covered her experience over the last 15 years working on WebKit and Chromium.

There is no paywall; give it a read!

@appfactory @glcst Hi, i'm pavan,

off-topic but is there any video where i can see how this works? https://t.co/pket5qpy2y

thanks.

Turso wants to match and surpass SQLite's reliability. When I say "surpass", usually ppl just look funny at me. But this is one such example: One of our OSS contributors have just found 10+ bugs in SQLite using validation he built for Turso. @pavan4820 used @quint_lang to build a formal model of the system and then executed its traces to find corner cases where SQLite deviated from the spec.

It is a great demonstration of how modern reliability tools, formal methods in particular, can lead to reliable systems and find *many* issues even on the most stable software on Earth.
