Decision

Routing decision: implementation_ready

Reason:

• Panel Queue により routing が明示的に許可され、Ticket は queued。
• Ticket body / thread / relation / OrchestrationPlan / Orchestrator workspace state を確認した。blocking relation はなく、planning に戻す concrete missing information はない。
• 対象は single-Pod conversation View の text-like Item selection/copy に限定され、Panel row selection とは scope が分かれている。
• Tool/non-text Item と copy target は implementation-time decision として許容されており、binding invariants / acceptance criteria / escalation conditions が明確。

Evidence checked:

• Ticket body/thread: requirements、copy target、tool/non-text handling、acceptance criteria、non-goals、related work を確認。
• Ticket relations: 00001KV072V89 と 00001KV10SN02 は related のみで blocker ではない。
• OrchestrationPlan: 既存 record なし。
• Orchestrator workspace: /home/hare/Projects/yoi/.worktree/orchestration は clean、f0de8413 上。
• Visible Pods: implementation child Pod なし。Intake peer は routing blocker ではない。
• Bounded code map: crates/tui/src/single_pod.rs、copy/clipboard abstraction、mouse/selection/key handling tests。

IntentPacket:

Intent:

• single-Pod TUI conversation View で User/System/Assistant など text-like Item の表示テキストを mouse drag で選択し、y で copy、Esc で clear できるようにする。

Binding decisions / invariants:

• 対象は single-Pod View Item text。Panel Ticket/Pod row selection は変更しない。
• terminal-native text selection preservation は non-goal。View drag は Yoi text selection として扱う。
• selected/copy text、selection state、clipboard diagnostics は Pod history / model context / session log / Ticket records に残さない。
• composer input、scroll、rewind picker、modal/popup、normal key handling と衝突させない。
• bare Panel row mouse selection semantics は regress させない。
• Tool/non-text Item handling と copy target は実装報告または decision comment に明示する。

Requirements / acceptance criteria:

• UserItem / SystemItem / AssistantItem text を drag selection できる。
• drag start/update/release 後に selection state が残り、View 上で highlight される。
• Esc で selection clear。
• y で selected text を copy し、selection clear。
• text-like Item を跨いだ selection が deterministic separator で copy される。
• non-text/tool item handling decision が明示され、test で固定される。
• copy 成功/失敗が user-visible で、secret-like diagnostics を出さない。
• tests cover coordinate mapping、selection state、multi-item extraction、Esc、copy+clear、non-text/tool handling。

Implementation latitude:

• Existing clipboard abstraction があれば利用。なければ testable な最小 copy path を追加してよい。
• OSC52/system clipboard/internal copy buffer の選択は既存 TUI architecture に合わせる。
• rendering/highlight 表現、selection model の internal shape、separator は実装側判断。ただし deterministic にする。

Escalate if:

• terminal/crossterm event stream で必要な drag/release を識別できない。
• existing rendering model から text coordinate mapping を安全に取れない。
• copy target を追加すると secrets/history/model-context boundary に影響する。
• rewind/modal/composer key handling と共存できない大きな model change が必要。

Validation:

• focused cargo test -p tui ... for single_pod selection/copy。
• cargo check -p tui --all-targets。
• cargo fmt --check。
• git diff --check。
• Panel row mouse selection regression test if related mouse plumbing is touched。

Critical risks / reviewer focus:

• selection/copy state の persistence leakage。
• mouse coordinate -> rendered text mapping correctness。
• multi-item extraction ordering/separator。
• composer/scroll/rewind/modal conflict。
• clipboard path safety and testability。
• Panel mouse behavior regression absence。

---

State changed

Routing decision と accepted implementation plan を記録済み。blocking relation / unresolved OrchestrationPlan blocker はなく、single-Pod View work は同時に開始する Panel composer work と主対象が異なるため、implementation side effects の前に queued -> inprogress acceptance を記録する。

Implementation report

Implementation report from Coder Pod yoi-coder-00001KV4YAAVY:

Commit:

• 09f5e9d5 feat: add single-pod text selection

Changed files:

• crates/tui/src/text_selection.rs
  • New transient selection state, coordinate mapping, extraction, and focused tests.
• crates/tui/src/app.rs
  • Local non-persistent selection state on App.
• crates/tui/src/ui.rs
  • Selectable history row metadata, highlight rendering, snapshot wiring, selectable/non-text tests.
• crates/tui/src/single_pod.rs
  • Drag mouse handling, Esc clear, y copy+clear, OSC52 copy, tests.
• crates/tui/src/lib.rs
  • Module registration.
• crates/tui/Cargo.toml, Cargo.lock
  • Added direct base64 dependency for OSC52 clipboard payloads.

Behavior / implementation decisions:

• Selectable Items:
  • UserMessage
  • SystemMessage
  • AssistantText
• Non-text/tool Items:
  • tool calls, thinking, stats, greetings, alerts, turn headers, etc. are not selectable/copyable through this path.
  • extraction skips non-selectable rows.
• Cross-item selection separator:
  • copied text follows rendered row order and preserves selectable blank spacer rows, giving deterministic \n\n between adjacent text-like Items.
• Copy target:
  • terminal clipboard via OSC52 (ESC ] 52 ; c ; base64 BEL), not OS clipboard APIs.
  • avoids adding platform clipboard runtime behavior.
• Copy diagnostics:
  • actionbar-only sanitized messages:
    • success: copied selected text to terminal clipboard
    • failure: terminal clipboard write failed
  • no selected content appears in diagnostics.
• Selection persistence:
  • selection state/copied text remains TUI-local only.
  • not appended to Pod history, model context, session logs, Ticket records, memory, or durable state.
• Mouse tracking:
  • single-Pod TUI now enables button-event drag tracking (?1002h) but not all-motion tracking (?1003h).
  • Panel code was not changed.

Validation reported by coder:

• Passed: cargo fmt --check
• Passed: cargo check -p tui --all-targets
• Passed: cargo test -p tui text_selection
• Passed: cargo test -p tui single_pod::tests
• Passed: cargo test -p tui ui::tests::history_rows_mark_text_items_selectable_and_non_text_unselectable
• Passed: git diff --check

Repository status:

• Child implementation worktree clean after commit.

Residual risks / notes:

• OSC52 clipboard success means sequence written/flushed; actual clipboard acceptance depends on terminal/multiplexer policy.
• No real PTY/E2E validation was run; coverage is focused unit-level mouse/key/selection/render extraction behavior.

Review: approve

Review result: approve

Evidence checked:

• Reviewed child worktree only:
  • /home/hare/Projects/yoi/.worktree/00001KV4YAAVY-single-pod-text-selection
  • diff 368249d6..09f5e9d5
  • Ticket record/thread in the child worktree
• Read-only validation:
  • Passed: git diff --check 368249d6..09f5e9d5

Implementation review:

• TUI-local selection state was added in crates/tui/src/text_selection.rs and wired into single-Pod rendering/input.
• Mouse drag maps terminal coordinates through HistoryViewport into rendered history rows.
• Drag start/update/release are handled in single_pod.rs; selection remains active after release.
• Esc clears selection before normal composer handling.
• bare y copies only when a selection exists; otherwise composer input remains available.
• Highlighting is applied through range_for_row and highlight_line_selection.
• Selectable item boundary is explicit:
  • selectable: UserMessage, SystemMessage, AssistantText
  • non-selectable: tool calls, thinking, notices, stats, greetings, etc.
• Tool/non-text rows are marked unselectable and extraction skips unselectable rows.
• Cross-item extraction is deterministic, with documented newline/blank-line behavior.
• Copy uses OSC52; selected text is base64 encoded before writing the OSC52 sequence.
• Copy diagnostics are generic/actionbar-local and do not include selected content.
• Selection state lives in TUI-local App.text_selection; no path was found that appends selected/copied text to Pod history, model context, session log, Ticket records, memory, or durable state.
• Mouse capture changes are limited to single-Pod fullscreen setup and avoid all-motion ?1003h; Panel/multi-pod mouse row selection code was not modified.
• Composer, scroll, rewind picker, completion/key routing, and normal key handling interactions were inspected and no blocker found.

Coverage reviewed:

• coordinate mapping
• drag update/release state
• multi-row / separator extraction
• non-selectable row skipping
• Esc clear
• copy helper + clear
• UI selectable/non-selectable marking
• mouse capture mode avoiding all-motion tracking

Non-blocking notes:

• No PTY/E2E validation was run; terminal-specific OSC52/mouse behavior still depends on real terminal behavior.
• OSC52 cannot acknowledge terminal clipboard acceptance; implementation can only report write/flush success/failure.
• There is no explicit byte-size cap on OSC52 payload, but selection is bounded by visible rendered viewport rather than arbitrary full history traversal. Future hard cap/error notice would be reasonable hardening.
• A full fixture test constructing an actual Block::ToolCall could strengthen coverage, but the non-text path is explicit and source-inspected.

Validation not rerun by reviewer:

• Cargo validation was not rerun because review scope was read-only and Cargo writes build artifacts. Coder-reported validation was inspected as evidence.

Conclusion:

• Approved. No blocker remains.
