📄 Description

Three technical documents analyzing OpenTUI's architecture, open issues, and development roadmap.

Documents Added

EXPLORATION.md - Repository structure, tech stack (TypeScript/Zig hybrid), feature inventory, 35 open issues prioritized by impact
ARCHITECTURE_DEEP_DIVE.md - Layer architecture, data flow diagrams, rendering pipeline (double-buffering, diffing, viewport culling), FFI boundary, layout engine integration
RECOMMENDATIONS.md - Issue priority matrix (12 categorized), code quality roadmap, architecture proposals (plugins, themes), 12-month path to 1.0

Key Findings

Architecture: Zig native layer (buffer management, UTF-8, rope data structures) + TypeScript API (components, reconcilers, Yoga layout, Tree-sitter highlighting)

Critical bugs identified:

CJK character corruption in reconcilers (#255)
Flex layout invalidation on state change (#391)
Nested ScrollBox clipping (#388)

High-impact needs:

Production deployment guide
Terminal compatibility (wezterm ModifyOtherKeys, tmux graphics leak, Kitty protocol)
Bytecode compilation (remove top-level await: 520ms → 44ms startup)

Documents provide onboarding for contributors and strategic context for maintainers.
