The Click Your Dashboard Filed Under “Direct”

Server-side click attribution: record the click at the link, before the browser can drop it. How HikrLink does it, the one thing it refuses to do, and the three wiring bugs we found joining it to our own tracker — none on the link side.

Architecture & Method

How the system around the model is built: gates, scaffolds, context delivery, and why structure beats instruction.

Architecture 2026-08

You Cannot Out-Coach the Scaffold

We put a mechanical grounding gate in front of our plan generator and watched violations fall from nine to zero across seven generations — without loosening the gate once. The last two defects lived in the generator's own scaffold and in the judge itself.

Essay 2026-06

The Model Is the Smallest Part

We bet the system around the model matters more than the model itself. Over the last few months, five independent practitioners and a frontier lab arrived at the same conclusion — none of them ours.

context-steward

Lazy skill loading for agent systems. Claude Skills are useful when loaded on demand, expensive when loaded up front. context-steward is the npm package that solves the second problem without breaking the first.

Essay 2026-05

The Boring Parts That Ship

Multi-agent delivery doesn't break on the model. It breaks on file conflicts, bad sequencing, and per-job metrics that miss the deployment. The unglamorous machinery that decides whether a sprint ships.

Evidence & Null Results

Measured findings, including the ones that said no. Nulls published next to wins — the method is the product.

The Checklists That Did Nothing

We built skill checklists for our agents, believed in them, and measured them anyway. Across 88 arm-randomised scored executions, quality moved +0.002 — inside the noise. The null, the method that caught it, and the boundary on what it does not say.

Independent Convergence

A running record of independent practitioners, an academic study, and frontier labs arriving at the conclusions we built on — in their own words, with dates, sources and caveats. Updated as the record grows.

We Deleted 20 of Our Own Quality Checks

We audited 36 mechanical quality checks and found about 20 had caught nothing in a month of production. The scaffolding you build for a weak model becomes a cage for a strong one.

Essay 2026-06

The Arithmetic of Absence

A GDPR-certified consent tool got a client fined anyway — because blocking a tracker doesn't make you invisible, it makes you a specific, reconstructable kind of missing data. On MNAR statistics, Bayesian imputation, and what enforcement actually catches.

Essay 2026-03

The 85% Accuracy Trap

Per-job quality scores in multi-agent systems almost always land around 85%. That number is telling you something different than you think it is. 4,600+ scored executions from our own production, and the pattern we found.

Essay 2026-04

The Median Trap

We ran a controlled A/B across 88 scored agent executions, with and without skill checklists in the prompt. Quality moved +0.002 — inside the noise. Why front-loaded instructions don't land, and what does.

Signals & Operations

Listening to production: telemetry, failure surfacing, and the feedback loops that turn incidents into structure.

How We Do SEO: Signals, Not Schedules

SEO as an instrumentation problem: four sensors, deconvolution that checks its own arithmetic, a hysteresis machine cleared through a four-run backtest, and a publisher that mechanically says no. Every decision leaves a receipt.

From 47 Minutes to 6 Seconds

The same failure surfaced twice in one day: 47 minutes in the morning, 6 seconds in the evening — a ~470× difference. Five changes, one principle: listen to the system's own signals.
