Product roadmap / 2026—2027
From the first reading to a system you fully own. Five quarters. One continuous evolution.

The foundation
Concept, brand system, website and web app.
Deterministic calculation from a 1900–2050 solar term table. Boundary resolution to the second, with true solar time correction by longitude.
Ten-stem relational mapping, classifying each of eight characters against the day stem and weighting them into five axes.
A living chart
Move chart data into stable memory inside the backend canister, with frontend assets served from a separate asset canister.
Build a daily layer on top of the fixed chart, mapping the current day’s stem against the user’s own into one of fifteen states across the five axes.
Derive ten-year and annual cycles from the month pillar, with direction set by year-stem polarity and sex.
A wider perspective
Locale routing with per-language copy files, adding support for additional languages.
Sun-sign derivation from the birth date and a sixteen-type mapping table, cross-referenced against the five-axis values through a divergence rule set.
Side-by-side axis comparison across up to five charts.
Your own infrastructure
A deployment pipeline with the controller key under direct custody, replacing the build platform’s managed canisters.
EVM sign-in through ic-siwe, mapping an Ethereum address to a principal deterministically, so the chart follows the wallet rather than the browser.
A city-level birthplace field feeding longitude-based solar time correction, replacing the single fixed meridian.
Privacy by design
A symmetric key derived from a wallet signature, with the payload encrypted in-browser before reaching the canister.
Aggregate counters exposed through a public query endpoint: reading volume, element distribution and day-stem frequency.
Automated coverage for the two points where a Four Pillars engine breaks: solar term boundaries and longitude-shifted hour pillars.
