M3 / 历史补录Historical backfill

方向编辑与线性历史Transforms and linear history

加入旋转、翻转和 Undo / Redo，让基础编辑保持可撤销。Added rotation, flipping and Undo / Redo for reversible image editing.

阶段已确认Phase confirmed
开发记录Development records 2026-10-06首次公开发布First public release 整理日期Prepared 2026-10-13

早期阶段完成记录及后续用户确认均可追溯至 2026 年 10 月 6 日。Early completion records and subsequent owner confirmation can be traced to 6 October 2026.

本阶段的变化What changed

  • 支持左右 90° 旋转，以及水平和垂直翻转。Added 90-degree rotation in both directions, plus horizontal and vertical flips.
  • 建立轻量编辑状态与普通线性历史；Undo 后的新编辑清除原 Redo 分支。Added lightweight edit states and ordinary linear history; editing after Undo discards the prior Redo branch.
  • 几何编辑继续使用只读原图，不为每一步历史保存完整图片副本。Geometric edits continue to use the read-only original without storing a full image for every history step.

验证与阶段结论Verification and outcome

  • 早期记录包含方向组合、状态与历史检查，以及 Debug / Release 构建和基本运行结果。Early records include transform combinations, state and history checks, Debug / Release builds and basic runtime results.
  • 用户随后明确确认 M1–M3 已完成。The owner subsequently confirmed completion of M1–M3.

保留的边界Remaining limits

  • 历史仅属于运行中的图片会话，不具备跨重启恢复能力。History belongs to the running image session and does not provide recovery across restarts.
  • 没有将有限运行验证扩大为完整环境验收。Limited runtime checks are not presented as comprehensive environmental acceptance.

本篇记录阶段当时的成果与验证范围。后续修复和新增能力另行记录，不能把旧候选结果继承给新版本。This entry records the phase outcome and verification scope at that point. Later fixes and capabilities are recorded separately; prior results do not establish a new candidate as passed.

项目与归档说明Project and archive notes

免费、本地优先、无账号的 Windows 多媒体处理与编辑软件。当前开发重心是图片工作区。A free, local-first Windows multimedia processing and editing application without accounts. Current development focuses on the image workspace.

铁柱 Studio 在建立公开开发日志体系之前，已开展多个阶段的开发。自 2026 年 10 月 13 日起，项目开始建立通过 untitled24 归档开发历程的体系。此前日志根据已有工程记录、开发文档和测试报告整理补录，持续记录开发过程、版本演进和项目成果。历史开发日期与实际日志发布日期分别保留。Tiezhu Studio had already progressed through several development phases before this public log was established. From 13 October 2026, the project began establishing its development archive through untitled24. Earlier entries are reconstructed from existing engineering records, development documents and test reports to preserve the process, version evolution and results over time. Historical development dates and actual publication dates are recorded separately.

这里公开阶段成果、验证摘要与必要的已知限制。内部实现、开发环境、源码和原始证据仅用于本地事实核对。This archive shares phase outcomes, verification summaries and necessary known limits. Internal implementation, development environment, source code and raw evidence remain local for fact-checking.
