# Archived Research Note This review was a useful snapshot on 2026-03-06, but many of its findings are now resolved or outdated. Examples that are no longer current: - Argon2 auth mismatch is fixed - notification permissions were tightened - resource detail content exists - timeline virtualization exists - Excel support exists - Redis-backed SSE work has already landed - Playwright E2E coverage is no longer empty Use [product-roadmap.md](/home/hartmut/Documents/Copilot/planarchy/docs/product-roadmap.md) for the active backlog and [v2-architecture-proposal-2026-03-11.md](/home/hartmut/Documents/Copilot/planarchy/research/v2-architecture-proposal-2026-03-11.md) for the still-relevant strategic direction.
