Summary

• make system-backed Windows console output temporarily own UTF-8 decoding and restore the exact prior output code page
• make Raw and CBreak input own mouse delivery while suppressing Quick Edit, with exact console-mode restoration
• retain Raw Ctrl+C/Ctrl+Z, Alt+F, Unicode input, cancellation, and lifecycle behavior
• publish the 1.29.2 version identity, concise README guidance, changelog history, and curated release notes
• move all 46 root development roadmaps under docs/ and repair their repository-relative references

Motivation

Live Icod.Dedit qualification exposed UTF-8 box-drawing bytes decoded under an OEM code page (─ rendered as ΓöÇ). The resulting multi-cell expansion broke popup borders and About-dialog geometry. Menu clicks were also unreliable because noncanonical Windows input did not explicitly own mouse and Quick Edit console flags.

The accumulated versioned roadmaps also obscured the repository root; documentation now has one consistent home.

Implementation

System-backed interactive Windows output now acquires UTF-8 console-output decoding alongside virtual-terminal output processing. The lease changes the code page only when needed, rolls back partial setup, and restores the captured value on lifecycle release, re-entry, and final disposal.

Windows Raw and CBreak mode policy now sets ENABLE_MOUSE_INPUT, ENABLE_EXTENDED_FLAGS, and virtual-terminal input while clearing Quick Edit. Raw continues to clear processed input so Ctrl+C and Ctrl+Z remain application keys; CBreak retains processed-input semantics. Canonical mode is unchanged.

All 46 current and historical development-roadmap Markdown files formerly at the repository root now live under docs/. Their links—and references from README, changelog, release notes, historical records, plans, and specifications—were rebased for the new location. The audit also repaired two older broken relative documentation links.

Validation

• Final PR run: 38939614526 — all 10 jobs passed on exact head 2cb41379b74b455d6a367ce329bbcff62523a90b
• Native Windows smoke passed actual one-cell box drawing, mouse/Quick Edit ownership, Ctrl+C, Ctrl+Z, following input, Alt+F, Unicode, cancellation, and exact input-mode/output-code-page restoration
• Runtime suites passed on Windows, Linux, and macOS
• Package build, all four contract shards, compatibility fixtures, public-API freeze, and validated artifact passed
• Documentation audit found no roadmap files remaining at the repository root and no missing repository-relative Markdown targets
• Red/green evidence:
  • 38846453404 demonstrated the missing UTF-8/output and mouse-mode behavior
  • 38846761191 passed after the implementation
  • 38847298056 demonstrated the 1.29.2 release-identity requirements before metadata was updated

Compatibility

No public API or production dependency changes. Targets remain .NET 8, .NET 9, and .NET 10.
