Show HN: Core – Constitutional AI achieving 70% autonomous coding
by d_newecki | 2025-11-28 22:57:07+00:00
I'm excited to share CORE v2.0.0, which just achieved A2 autonomy: 70% success rate on autonomous code generation with constitutional governance.

The problem: AI agents can write code fast, but they also break architecture, skip tests, and ignore conventions.

The solution: Constitutional governance. Every AI action goes through: - Constitutional audit (checks architecture, naming, placement) - Semantic validation (513 symbols in knowledge graph) - Test execution with auto-fix - Clean merge only if everything passes

Real metrics: - Code generation: 0% → 70% success - Semantic placement: 45% → 100% accuracy - 513 symbols vectorized, 66 module anchors, 48 policy chunks

The key innovation is making AI autonomy safe through human-authored policies that AI semantically understands. Agents operate in defined "autonomy lanes" with cryptographic governance for policy changes.

Built with Python, PostgreSQL, Qdrant. MIT licensed.

Next milestone: A3 (strategic refactoring across multiple files).

Happy to answer questions about the constitutional governance approach!

The idea is that if you're winning you can just do a binary search, but if you're losing, it's better to take some risks by making narrower guesses.

For example, let's say it's the last turn and your opponent is about to win. Say you may have 2 options but your opponent has 4 options. Instead of whittling it down to 2 options, it's better to guess one of the four. How outrageous should your guesses be is the content of the result and paper.

Paper is on archive (and linked from the video):

> Typewriters and printing presses take away some, but your robot would deprive us of all. Your robot takes over the galleys. Soon it, or other robots, would take over the original writing, the searching of the sources, the checking and crosschecking of passages, perhaps even the deduction of conclusions. What would that leave the scholar? One thing only, the barren decisions concerning what orders to give the robot next!

On the Qantas 72 flight (2008), the ATSB report showed the same power spike that upset the ADIRU also left tidy 1-word corruptions in the flight data recorder. Those aligned with the clock cycle, shared the same amplitude and were confined to single ARINC words. That is pretty much exactly the signature of a failing solid state relay or contactor on the shared avionics power bus (upstream of both FDR and fly by wire).

Radation-driven bit flips would be Poisson distributed in time and energy. So that is one way to find out

I’ve been building a small, Rust-based microkernel real-time OS as a long-term personal project. It currently includes a microkernel, process and thread manager, memory manager with paging, filesystem, basic drivers, and a simple shell. It runs on Raspberry Pi hardware and QEMU.

My next goal is to evolve Tail OS into a robotics-focused OS, with more deterministic scheduling, safer IPC, and support for common robotics interfaces.

If you have experience with robotics, embedded systems, or real-time OS design, I’d love feedback on what features or constraints matter most.

Technical overview and architecture: https://tail-os.com/README/

Thanks!

What a nice story! Cleaning up eyebrows shows nicely the discrepancy between intimacy (feeling love and care) and erotica (feeling lust?).

The hair grooming in the article probably felt similar.

Thinking about the physio therapy, her upper body felt very warm and soft but it was probably a rather standard technique for firmly moving the joints and ligaments in legs and hips.

What it made most intimate was not just the softness of her body but also the care she took for the movements, knowing that it would help.

So my limbic system went into oxytocin producing mode, which the aware mind easily picks up with warm thoughts. I think that's where the bridge between intimacy and sexual thoughts can happen, but there my thinking was not firmly going into that direction, it just felt warm and comfortable, even a bit emotional.

In your case the feelings apperently came from both directions, it was not a professional/client context after all.

I disagree with this 100% most of the time I see the typo and move on because using my thumbs to delete and break the flow is way too much effort. This message alone had a dozen auto corrects passively because thumbs are bigger than keyboard buttons...... Thumb typing on a slippery glass brick is not pleasant. It's not that hard to understand.

There is no "thousand colonies". There might be one colony, and that might not ever be self sufficient.

Interstellar travel is a physics problem, not an engineering one. Even make believe nuclear propulsion is still aggressively limited by the rocket equation and still wont get you anywhere in a meaningful time frame.

There will never be an interstellar empire. It will never make sense to do trade between two planets that are otherwise capable of producing things, because the energy cost of doing anything in space absolutely dwarfs any possible industrial process. It doesn't matter how low quality your local iron ore is, importing ore from a different planet will never be a better option because transportation costs are effectively infinite.

Human trade is almost entirely based on the fun quirk that sea based transportation is ludicrously efficient, such that you can ship a single pound of product all over the globe and it can still be cheap. The physics of space are essentially the opposite of the physics of sea travel, in that it is dramatically harder and more energetically expensive than almost anything else you can do, and the energy regime it operates in will dwarf any other consideration.

If there was a magical way to turn joules directly into a change in kinetic energy, as in a machine that could magically extract every joule of "energy" from matter in an E=mc^2 way and directly reduce an object's kinetic energy by that much, taking a 100 kilogram human up to half the speed of light and eventually slowing them down again would take 31 kilograms of matter to "burn", and you have to accelerate all that matter too. That matter would require another like 10kg of matter to "burn" and then you have to accelerate that matter too and so on and so on.

And we do not come even remotely close to any mechanism, real or theoretical, that could convert mass to a change in kinetic energy. Even if you had like a magic antimatter machine that could come very close to turning a gram of matter into it's entire "energy" content, ways of turning thermal or electrical energy into thrust have their own inefficiencies, difficulties, and do not even come close to mapping to "Each joule of energy equals a joule of kinetic energy change".

And even with our magic spacecraft machine that cheats physics, that's still an 8 year round trip to Alpha Centauri and back, with something like a 50%-65% payload fraction.

The scale of things in space combined with the nature of that space makes interstellar anything nonsensical. Even interstellar travel of just information is fairly mediocre. SciFi will never exist in our world, and at this point should probably just be called "Fantasy with more plastic"

I am not a developer at all (electrician, retired, live in a flightpath), but I'm pretty sure you can build a healthy retirement with your absolutely breathtaking solo project.

At the same time, I'm not sure how you monetize such an easily "stealable" idea. My hunch is that you'll see other flight trackers debut your perspective as one of many layers within their own trackers (this is where you come in, as consultant?).

Godspeed, ace.

Used an LLM to help write the following up as I’m still pretty scattered about the idea and on mobile.

——

Something I’ve been going over in my head:

I used to work in a pretty strict Pivotal XP shop. PM ran the team like a conductor. We had analysts, QA, leads, seniors. Inceptions for new features were long, sometimes heated sessions with PM + Analyst + QA + Lead + a couple of seniors. Out of that you’d get:

- Thinly sliced epics and tasks - Clear ownership - Everyone aligned on data flows and boundaries - Specs, requirements, and acceptance criteria nailed at both high- and mid-level

At the end, everyone knew what was talking to what, what “done” meant, and where the edges were.

What I’m thinking about now is basically that process, but agentized and wired into the tooling:

- Any ticket is an entry point into a graph, not just a blob of text. - Epics ↔ tasks ↔ subtasks - Linked specs / decisions / notes - Files and PRs that touched the same areas

- Standards live as versioned docs, not just a random Agents.md:

- Markdown (with diagrams) that declares where it applies: tags, ticket types, modules. - Tickets can pin those docs via labels/tags/links.

- From the agent’s perspective, the UI is just a viewer/editor. - The real surface is an API: “given this ticket, type, module, and tags, give me all applicable standards, related work, and code history.”

- The agent then plays something like the analyst + senior engineer role: - Pulls in the right standards automatically - Proposes acceptance criteria and subtasks - Explains why a file looks the way it does by walking past tickets / PRs / decisions

So it’s less “LLM stapled to an issue tracker” and more “that old XP inception + thin-slice discipline, encoded as a graph the agent can actually reason over.”

I’m not really sure about that. I think if I told most people in my social circles that, they would look at me like I’m very weird.

I’m not necessarily saying they are wrong either. It’s a tough zone. If I imagine people I know saying that to me, in my head most of them come off lecherous and creepy.

I feel like close friends could say that stuff to me or vice versa but most of the time it would come off weird at best. Choice of words is also a big factor though. “Beautiful”, “gorgeous”, “attractive” are all more reasonable sounding to me than “hot” even though they all basically mean the same thing.

I don't think we're at odds here!

One possible solution to my framework is (1) to only buy things for which you have a coherent theory (2) that coherent theory holds water over the duration of your investing life.

It's possible that you had a coherent theory for purchasing TSLA at a certain price. If that price has out-run your theory, there is no contradiction in selling that TSLA and parking it in some place you have a coherent theory for, like VOO. This is maturity and humility, not hubris.

If I were in your position, I'd try to ask myself: does this decision to rollover TSLA into something I better-understand (e.g. VOO) fall inside or outside the pattern of "my own personal financial history has been more damaged by actions taken".

FWIW, "Time in beats timing" is a truism that applies to market-spanning indices, not a choice between individual securities. It would be a mistake to apply that logic to individual positions, unless you've given yourself the arbitrary restriction of only buying or selling TSLA and nothing else!

> Intel isn't a competitor to either TSMC or Samsung, their fab process is years behind.

Is it? I've read that Intel's newest process is closer to TSMC N3 than N2, but surely it's not years behind Samsung? I think the biggest problem for Intel right now is acquiring customers and learning how to work with them (but the new CEO should be the right person to do that).

I'd venture the way these accounts work is they make literally thousands of social-media platform accounts.

I have a (very) small forum (maybe 100 active users), and it gets multiple bot signups every day, almost all from Russia or other bloc/satellite countries (or laundered through an obvious VPN). If we didn't filter them, we would have tens of thousands by now making hundreds of thousands of posts per day on a forum that gets maybe 20 posts per day.

> The reason Congress doesn't do anything is because it ceased to be a functioning body sometime around the AUMF.

That was kind of my point, I just didn't want to write an essay about it. Congress does nothing therefore the only tangible change happens from one guy signing whatever he wants to sign into the law, effectively reducing three branches of government down to one. That said, I sure can point to for example Trump essentially taking over the power to impose tarrifs away from the congress and congress doing absolutely nothing to assert what was previously widely understood to be 100% within their authority. Or dozens of people that were deported despite various courts literally ordering the administration not to do that, Kilmar Abrego Garcia being just the first of them.

> I guess the only thing saving the EU from the same fate is its powerlessness and indecisiveness. The people who run it are certainly insane in the same way as the leaders of the UK and the US.

Now here we vehimently disagree. Nobody "runs" the EU. You need something like 500 people to agree on something for it become a law. Each of those represents their nation, their party, and their EU-level coalition. The biggest countries don't get to impose a change on smaller countries, the smallest countries don't get to do so either.

It is by far the most complex political system we have in the world for a very good reason. It came from decades of negotiating and re-negotiating between countries. It set some base standards that apply equally to otherwise incomparable nations. It is not meant to move fast and break things, it is meant to be slow and ineffective because every decision it makes impacts people that have absolutely nothing in common except the fact that they all volutarily joined the EU. From Finland to Portugal, from Cyprus to Ireland. Seriously, name me one other thing that those four countries have in common. Two of them are not in NATO, one of them is not even in Europe geographically-speaking, but I guess they all kinda like football? The fact that the EU does anything at all is a miracle of human cooperation.

And we're comparing it to one guy with questionable mental capacity (to say the least) signing things into law. Give me a break. The biggest "problem" with the EU is that at least 95% of the population that like to shit on it as an institution haven't invested more than 10 minutes into trying to understand how it works, yourself very much included.

Actual title:

"Your Phone Isn’t a Drug. It’s a Portal to the Otherworld."

Not just moving pictures, but windowed images, can be hypnotic.

Especially the more realistic or seemingly 3D, whether it's spatial depth or nested links.

Alice's Adventures reflects on a time when people were just getting accustomed to decent mirrors of increasing size, but they were nowhere near as common as today. Similar to movies, TV sets, CRT computers, and flat screens down to pocket-size, different people will be intrigued in different ways, especially on first impression. The imagination can often be triggered by the feeling that there is so much more beyond the "porthole", that is there but can not seen so easy.

Sometimes deeper engagement seems to reveal more, like changing channels or scrolling toward doom, which can be satisfying to an extent, other times there's no way to get deeper in and from that point may rely on pure fantasy as to what it's actually like to participate if you were not just confined to observing the images.

I guess that's how you end up with such a seemingly exaggerated account of what it's like "through the looking glass" :)

> https://en.wikipedia.org/wiki/Air_France_Flight_447

Quoting your link, "Final Report" section:

> Temporary inconsistency between the measured speeds, likely as a result of the obstruction of the pitot tubes by ice crystals, caused autopilot disconnection and [flight control mode] reconfiguration to "alternate law (ALT)".

- The crew made inappropriate control inputs that destabilized the flight path.

- The crew failed to follow appropriate procedure for loss of displayed airspeed information.

- The crew were late in identifying and correcting the deviation from the flight path.

- The crew lacked understanding of the approach to stall.

- The crew failed to recognize the aircraft had stalled, and consequently did not make inputs that would have made recovering from the stall possible.

Note the numerous "the crew"

> As you’d expect, this makes Tauri apps far more lightweight.

Note that lightweight compared to Electron does not mean it's actually lightweight. In my experience, Tauri apps are still pretty heavy and a constant drain on system resources; maybe they're 2x better (faster/lighter) compared to an Electron equivalent, but they're still at least 10x worse compared to native apps.

With a Tauri-based app (just like with Electron), I have to constantly remember to close the app at the soonest possible point in time, or I can tangibly feel the sluggishness it creates in the system performance. So if there's a native choice and a Tauri-written choice, I'd heavily prefer the native choice nowadays, even at the cost of some features.

Because businesses, as a rule, value moving fast. Being first to market makes money and generally results in winning.

Oftentimes the circumstances are "we don't know the requirements", not because of shitty management, but because the problem is inherently hard to define.

The business conditions that do heavily penalize bad architectural decisions, like physical structural engineering, can suck to work in compared to SWE.

It takes a decade or more before you're trustworthy enough to architect a building and there's a million layers of approvals. Then it takes years before groundbreaking, and years more as the building increases in size.

Your whole life might be dominated by a single large project like Hudson Yards, which has been floating around as an idea since 1956. The most recent proposal started in 2006, broke ground in 2012, and another 6+ years to finish. Then when companies were about to move their offices there, COVID-19 happened and the leases fell through.

I'd rather the system that gives average SWEs regular opportunities to lead large projects from scratch and make mistakes.

The problem is not using parallel tool calling or not returning a search array. We do this across large data sets and don’t see much of a problem. It also means you can swap algorithms on the fly. Building a BM25 index over a few thousand documents is not very expensive locally. Rg and grep are freeish. If you have information on folder contents you can let your agent decide at execution time based on information need.

Embeddings just aren’t the most interesting thing here if you’re running a frontier fm.

> The fact is that our most intimate interactions with others are now governed by the expectation of surveillance and punishment from an online public

It's a horrible way to live your life. But it doesn't have to be this way. This has to be this way only for terminally online people. If you don't go to twitter, there's no importance to anything anybody on twitter thinks about you. Of course, for certain people, like actors, politicians, top-level entertainers and so on, there's no other way to achieve anything now, but for most people it's entirely optional. You don't need to be on twitter (substitute any social media here) to be a good teacher, farmer, programmer, designer, builder, gardener, nurse or car mechanic. It's still completely voluntary so far.

I love beeper and have been using it for a very long time at this point, but I wouldn’t go as far as calling it a good client.

Whatsapp mentions don’t work (just show the name of the mention to the other users), and polls or albums don’t work.

Messenger disconnects every couple of days at this point.

Pasting links won’t always expand.

Attachments are always hit or miss.

So many small other things. Still love it.

Maybe it's things like 4-year tenure, or shorter tenure, or something else.

But I think it's a matter of motivation, Bob.

> The thing is, Bob, it's not that I'm lazy, it's that I just don't care. It's a problem of motivation, all right? Now if I work my ass off and Initech ships a few extra units, I don't see another dime, so where's the motivation? ... my only real motivation is not to be hassled.

I think it's a quite fair assessment. It's not an indictment of their engineering or anything, but they can't say for sure what caused the issue and the analyzed all they could. The conclusion is "we don't know, we have some guesses". Probably it irks me the most because "cosmic rays" are impossible to prove. It's the perfect scapegoat. If I had a penny every time that someone put it out as the possible cause of a bug... I'd still be poor, but... well, I'd have a couple of pennies.

EDIT: On a deeper read, I am inclined to be a bit more charitable to this theory because, to my surprise: "As noted in section 3.5.2, the CPU module on units 4167 and 4122 did not incorporate EDAC"

I did not consider these units were _this_ old, so they did not have error correction on them. Nowadays, most every MCU has ECC on them. So, yes, without ECC the odds are quite larger that they DID get a "bit flip"
