StateLens keeps a small trail of meaningful moments, so you can understand what happened later without recording your whole life.
The useful part of a day is often not every minute. It is where attention changed, a problem appeared, a decision settled or something became worth remembering.
You started by browsing several pairs, narrowed the choice to two, and chose the more comfortable pair even though the other pair was cheaper. The decision was settled at 10:37.
StateLens is useful whenever the important part is how a situation changed—not a complete recording of everything around it.
A machine starts sounding wrong. You stop, inspect it and later replace a worn part.
You put your keys somewhere unusual while carrying groceries inside.
You compare products, reject one because of price and choose another because it will last longer.
You reach a new area, change your character build and stop playing before the next quest.
A train is cancelled. You choose another route and arrive through a different station.
A small thought appears during a walk, becomes a clearer concept and turns into a project note.
You begin with a question, compare explanations and finally reach an understanding that feels stable.
You notice a leak, discuss whether to repair or replace something and agree on the next step.
You agree to bring something, call someone or finish a small task later in the week.
A StateLens trail is intentionally small. It records only enough structure to make the sequence understandable later.
A question opens, attention narrows, a conflict appears, a choice settles or a task finishes.
A short phrase such as “record this,” “remember this decision” or “save where I stopped.”
Time, a simple context label and the kind of change that occurred.
Later, the trail can answer what opened, changed, broke, settled or still needs attention.
Only the moments that changed the situation are kept.
A person asks a normal question rather than reading technical logs.
StateLens is built around selective state entries. The goal is useful continuity with less raw personal data.
The State Diary is the everyday form of StateLens. Underneath it is a small shared vocabulary that lets moments remain consistent across AI assistants, devices and future interfaces.
A person sees plain language. A system can keep a stable operator alongside it.

StateLens is published as a state-first, URL-native grammar for reconstructable situations. The technical pages describe the operators, addressing model, provenance trail and broader ambient use.
