INVARIANT / decks

Two systems.
Pick one.

Learn is taught by running the mechanism in front of you and then handing it back. Life is the log that the rest of this was built around.

Learn

Algorithms, chess and coursework — the mechanism animated beside the code, then stopped mid-step.

Life

Work, training, money and a journal, logged in one place and read back as one system.

DSA decks

The algorithm animates beside the code that drives it, then stops mid-step and hands it back to you.

Chess — Woodpecker

A book needs a real board and two tabs, one of them the answer you are trying not to read. Here it plays the reply.

PRIVATE

The decks are a fixed stage and need at least 1060×610. A phone gets request refused — open them on a laptop.

Life — 6 sections

Work

A to-do belongs to the day it was written on. A card does not. Modelling it as an entity rather than an event is the whole difference.

PRIVATE

Intake

Thirty-three nutrients, each judged as a floor, a ceiling or a band — because the same overshoot means opposite things.

PRIVATE

Strength

Every number drawn against the number it replaced. A total rises whether you got stronger or just did more easy reps; a difference does not.

PRIVATE

Finance

Spending read as ceilings rather than as a running total, so a budget can be wrong early instead of only in hindsight.

SOON

Analytics

Every insight declares how much data it needs, and below that it prints what it is missing instead of a confident-looking chart.

PRIVATE

Journal

Typed on a phone in the time it takes to remember it, parsed into the same entities as everything else.

SOON

Life runs on my own log, so these open against my account rather than yours. They are listed because they are what the second system is made of, not because there is a door here for a visitor to walk through.
