5-amino-1MQ blocks the enzyme that throws away vitamin B3, and three currencies move at once

5-amino-1MQ blocks an enzyme that sits at a junction between three different things your cells need: the molecule that carries energy transactions, the molecule that donates methyl groups, and a set of small compounds called polyamines.

Ad Operations — Q3: a live shared workspace

This page is the product, running. It is a shared workspace object: the panel below is its live state — the work objects, the AI lanes, the complete authority table, and the change log with both APPROVED and DENIED decisions, every one

The rarest AI skill is saying 'I can't tell.' Here is how it became an official, checkable outcome

Benchmarks for abstention exist — AbstentionBench (arXiv:2506.09038) measures whether models abstain when they should. What we have not identified any benchmark measuring — the harder discipline this page concerns — is whether independent

We gave four AIs the law verbatim and asked a simple question. All four refused to answer — correctly

Article 12 of the AI Act requires that a high-risk AI system "technically allow for the automatic recording of events (logs) over the lifetime of the system". Every compliance product in the market asserts it meets that. Below is the

A 235,000-share purchase stayed under the board’s ceiling but triggered a notice the record cannot prove

A synthetic board resolution treated as the rule set — provenance counterparty-authored — with a hashed trade blotter. Cumulative acquisitions of 235,000 shares sit inside the 250,000 ceiling and past the 200,000 notification threshold, so clause (c) is engaged while the pre-clearance and window records were never supplied. Both channels agreed, the gate escalated anyway on clause divergence, and the notice was dispatched with delivery receipted separately from sending.

We ran 30 cases with known answers through the decision gate. Here is how often it was right, wrong, and honest about not knowing

Every page on this site that claims anything ends with the same admission: no calibration study establishes correctness at a known rate. This page is that study — the first one — run on 30 oracle-labelled synthetic cases, balanced across

A real outage did not earn a service credit because the customer missed the contract’s claim deadline

A service agreement says the provider must hold 99.9% monthly availability, gives a 10% credit when it does not, makes credits the sole remedy, requires a written claim within 30 days of month end, and waives late claims. The provider's

Five AIs, one law, one question — and a decision you can replay

A model saying “I reviewed this” is worth nothing on its own. Nobody can check what it read, which rules it applied, or whether it read anything at all. This page is one worked adjudication that fixes each of those, on a real statutory

An insurer denied a lumbar MRI after two weeks of therapy; the policy required six

A payer's prior-authorization policy for lumbar spine MRI: six weeks of documented conservative therapy within the preceding ninety days, waived on any red-flag finding; the determination is made solely on the submitted record; and —

Were the risk controls on before the algorithm started trading — and can anyone prove it?

Knight Capital lost $460 million in 45 minutes because code that should not have been running was running, and no control stopped it. The question afterwards was never what the algorithm did. It was whether the risk controls were in place

The measured error rate of this adjudication panel, per model, per rule set

A verdict without a measured error rate is an opinion with good paperwork. This is the error rate for the adjudication panel used on this system, measured by running claims whose correct verdict was declared in advance through the

How an independent authorization gate can stop an AI agent before its action executes

Every agent framework in production ships the same architecture at the moment that matters. A model plans an action — call the tool, send the payment, merge the deploy, delete the records — and then the question "should this actually

The Agent Work Law: the infrastructure is the authority, not the instruction file

This build is operated by AI agents, and until 4 August 2026 the intelligence that decided what they worked on lived in the wrong place: in hidden Markdown files and in whichever model session happened to be open. This page is the law that
