Result / 用户结果

Recognized completed Markdown, JSON and Git commands can display native results in the terminal with one shared vertical viewport. Markdown keeps selectable text, compact headings, code blocks and tables; JSON supports filtering/sorting. Ordinary directory output keeps its original terminal colors, links and selection, with only the middle folded when it exceeds 20 rows: the first and last ten remain visible and can be expanded.

The explicit pebrel view --type markdown|table|git entry supports native-capability negotiation and plain redirected output. Its Git capture preserves separate stdout/stderr streams and displays progress while the child runs. Ordinary Git command capture applies only after eligible successful completion. Windows packages include a console pebrel.com entry for correct pipeline/wait/exit behavior.

原生结果共用终端滚动和坐标映射。Markdown、JSON 与 Git 输出贴合内容显示，操作在悬停或键盘焦点时出现；普通目录输出保留原始颜色、链接与选区，只折叠中间行，前后各保留十行并支持展开。

This PR is stacked on #704. Structured Git diff headers/paired line numbers follow in a separate PR. The right-click behavior correction is independently tracked by #703.

Design / 设计边界

• A single source-to-visual projection governs rendering, pointer coordinates, links, selections, search highlights, scrollbar and following-prompt placement. Natural result height does not insert/delete VT rows or resize the PTY.
• Result-owned tasks and retained entities preserve parsing, code-language selection, filtering and copy feedback across scrolling. Eviction releases them. Stale results cannot overwrite newer query state.
• Table parsing/materialization is bounded; invalid or oversized data retains its source. Captured ordinary output is VT display text, while explicit native payloads retain the supplied text.
• Commands are not re-executed to produce views. Output previews do not fetch remote images or load arbitrary HTML/local media. Directory folding reuses real terminal links rather than reconstructing paths.
• Protocol storage is in Retain bounded command output at stable terminal surface anchors #704. This PR contains the complete renderer, its public CLI entry and packaging adaptation, with existing ownership notes under architecture/notes/.

Evidence / 验证依据

• JSON rows have stable source-row element identities. The cached-parent regression failed before the fix and passes afterward; the maintainer confirmed the hover background follows the pointer in the actual preview on 2026-10-21.
• Native output retains its measured fractional-row height. The default PowerShell prompt now inserts a leading newline only when the prior output has left the cursor partway through a line, so completed lines do not gain another blank line before the path. Both Powerline modes retain separation after output without a final newline; custom prompts keep their own layout.
• Six real-console cursor/spacing cases covered first prompt, completed-line output and partial-line output with Powerline on/off. The previous script failed both completed-line cases; the corrected script passed all six. Fifteen existing PowerShell integration tests also passed, including custom prompts, Conda/venv, exit status and completion ownership.
• The integrated source passed 30 reading tests, three projection tests and 15 pointer tests for real hover/copy/filter/sort controls, natural height, retained identity, prompt placement, original links and selections. The version-checked optimized dev product includes the prompt-spacing correction; final spacing acceptance remains pending. No numeric latency/FPS claim is made.
• Architecture, Rust formatting, platform budgets and diff checks passed without increases. Shell completions include pebrel view; Windows build-selection/package and CLI branding checks passed in the feature validation.
• Exact-head native CI for 0fe0ee2e is running. The preceding hover-fix head passed Linux, Windows x64 and macOS Intel; Windows ARM failed the existing Git Bash wrapped-input erase case (3,172 passed / one failed). That failure remains unresolved; successful report checks are not treated as additional native executions. Full release packaging and cross-platform desktop acceptance are separate.

Review size

Counted source changes: 4,869, below the absolute 5,000-line ceiling. The default 1,500-line limit requires an individually approved size-exempt label. The maintainer approved a one-time size-exempt exception for this PR on 2026-10-21; it does not waive native CI, visual acceptance, or the absolute ceiling. The shared viewport and its rendering/input consumers are kept together so reviewers can verify one coordinate authority; the terminal storage and structured diff feature have separate review boundaries.

Required Review / 必须确认

• Followed contribution, architecture and project constraints.
• Kept one shared viewport/selection authority and cohesive feature boundaries.
• Architecture, formatting and platform budgets pass without increases.
• Stated actual tests, physical acceptance limits and pending exact-branch CI.
• New UI text uses typed messages with explicit language fallback.
• Maintainer approved this PR's one-time default size-limit exception.
