Roadmap

⚠️ Status: stale (last updated 2026-04-01). This document reflects the strategic vision from early 2026. Many short/medium-term items have been superseded by the mobile consolidation and web migration. For the current, prioritized view of technical debt, in-flight migrations, and immediate improvements, use the live Technical Debt & Improvements register instead.

See also: tech-debt/migrations.md for the three active migrations (mobile consolidation, web frontend, design tokens) and tech-debt/README.md for the prioritized P0–P3 backlog.

This document outlines the technical roadmap for Oter, organized by time horizons.
