🤖 Delete solver abstains on issue 38

TL;DR

• What this is: Delete-role design consensus output for issue TUI composer wedges on tmux paste-buffer + immediate Enter: bracketed-paste state not exited before submit (codex-cli 0.139.0) #38.
• Current state or conclusion: I found active, load-bearing TUI paste paths, so deletion/collapse is not justified.
• What the maintainer should do OR what the controller does next: Controller should prefer a minimal TUI fix and regression coverage rather than deleting paste handling.

---

Delete-role assessment

I abstain from proposing deletion. TuiEventStream is the TUI event adapter that turns crossterm terminal events into Codex TUI events; it maps explicit bracketed-paste payloads into TuiEvent::Paste, which the app then forwards into the chat composer. PasteBurst is the fallback state machine for terminals that send paste as rapid KeyCode::Char and KeyCode::Enter events instead of a single paste event.

These are separate responsibilities, not duplicate implementations. Removing the explicit paste path would break bracketed multiline paste. Removing PasteBurst would regress non-bracketed paste behavior where Enter must stay a newline inside the paste instead of submitting the composer.

Key evidence:

• codex-rs/tui/src/tui.rs:176 enables bracketed paste and codex-rs/tui/src/tui.rs:256 disables it during terminal restore, so this is active terminal-mode behavior.
• codex-rs/tui/src/tui/event_stream.rs:248 maps Event::Paste(pasted) to TuiEvent::Paste(pasted), which matters because bracketed paste enters the app through this path.
• codex-rs/tui/src/app.rs:1263 forwards paste payloads into the chat widget after CR-to-LF normalization, which matters because multiline paste should become composer text before submission.
• codex-rs/tui/src/bottom_pane/paste_burst.rs:1 documents the non-bracketed paste state machine, which matters because it prevents rapid pasted Enter events from becoming submit commands.
• codex-rs/tui/src/bottom_pane/chat_composer.rs:3217 accumulates Enter as a newline during a paste burst, which matters for the exact class of newline-as-submit failures.

The issue still looks real and bounded, but the delete-role conclusion is that the fix should be behavioral and focused, not deletion-driven. The issue body’s reference to codex-apply-patch tests looks inconsistent with the local evidence, which points at codex-tui paste/input handling.

solver: delete
issue: 38
cluster: issue-38
verdict: abstain

Classification

e) Genuinely needed and right-sized for the existing paste-input responsibilities; no current deletion/collapse is justified for issue 38.

Recommended action

不建议删除或合并现有 paste 处理路径。当前代码有两条不同且必要的输入路径：TuiEventStream 将 crossterm 的 bracketed paste 映射为 TuiEvent::Paste，应用层再把它送入 composer；PasteBurst 则处理没有可靠 bracketed paste 的终端，把快速 KeyCode::Char/KeyCode::Enter 流识别为 paste-like burst。Issue #38 描述的是 tmux paste-buffer 后立即 Enter 的 bracketed-paste 退出/提交竞态，属于需要最小修复和回归测试的真实 TUI 行为问题，不是死代码、孤儿功能或重复抽象。删除任一路径都会移除多行粘贴或非 bracketed paste 支持，因此 delete solver 应 abstain，让 minimal/structural solver 设计修复。

Concrete plan (if propose)

• Files to delete: none
• Caller migrations: none
• Tests to delete: none
• LOC delta: 0
• Philosophy/CLAUDE.md/SPEC/Tier changes (if any): none
• IssueDecompositionPlan: not applicable; the issue is bounded to TUI paste/input handling and does not need decomposition from the delete role.

Reverse-evidence (why this is safe to delete)

• Not safe to delete: codex-rs/tui/src/tui.rs:176 enables bracketed paste and codex-rs/tui/src/tui.rs:256 disables it during restore, so bracketed paste is an active terminal mode, not a stale branch.
• Not safe to delete: codex-rs/tui/src/tui/event_stream.rs:248 maps Event::Paste(pasted) to TuiEvent::Paste(pasted), and codex-rs/tui/src/app.rs:1263-1269 normalizes and forwards that payload to the chat widget.
• Not safe to delete: codex-rs/tui/src/bottom_pane/mod.rs:707-724 routes explicit paste to the active bottom-pane view or primary composer, while codex-rs/tui/src/bottom_pane/mod.rs:1513-1531 flushes paste-burst state for both active overlays and the primary composer.
• Not safe to delete: codex-rs/tui/src/bottom_pane/paste_burst.rs:1-17 states the non-bracketed paste responsibility: avoid shortcut side effects, keep Enter as newline during paste, and avoid flicker.
• Not safe to delete: codex-rs/tui/src/bottom_pane/chat_composer.rs:92-125 documents the same state machine from the composer side; chat_composer.rs:3217-3223 accumulates Enter as a burst newline, and chat_composer.rs:1518-1540 exposes the timed flush path.
• No public API deletion path was found: this is user-facing terminal behavior inside codex-tui; the issue asks to verify and fix, not to retire a feature.
• Existing tests are load-bearing rather than removable. For example, codex-rs/tui/src/bottom_pane/chat_composer.rs:7354-7379 verifies that slash command Enter dispatch still wins over paste-burst suppression, which protects a real edge case.

Risks

• If the actual upstream reproduction shows crossterm emits a plain KeyEvent::Enter after Event::Paste in the same tmux paste-buffer action, a minimal fix may need a tiny post-explicit-paste guard, but that is additive/behavioral and not a deletion.
• If tmux sometimes bypasses bracketed paste and emits rapid key events, PasteBurst is the existing fallback path that prevents exactly the newline-as-submit class of bug; deleting it would make the regression broader.
• The issue body mentions "codex-apply-patch tests", but local evidence points to codex-tui paste/input handling. Treat that as a likely mirrored acceptance-text mismatch unless another solver finds an apply-patch-specific reproducer.

Escalation triggers (if any)

• none

Reasoning trace (internal — for meta-judge)

• Reference-frame note: terminal input state machines should preserve distinct transport semantics, separating explicit bracketed paste events from heuristic key-burst paste detection; collapsing them without a proven equivalence would lose observable behavior.
• Why I claim this can be deleted: I do not claim deletion is safe. The delete role abstains because both paste paths are active and user-visible.
• What I checked to verify safety: searched TUI paste/bracketed-paste call flow; inspected tui.rs terminal mode setup/restore, tui/event_stream.rs crossterm mapping, app.rs TuiEvent::Paste handling, BottomPane paste routing and burst flushing, PasteBurst state-machine docs and methods, ChatComposer paste-burst integration, existing tests around Enter suppression, and git history for the original intent of bracketed paste and paste-burst handling.
• What I cannot decide alone: the exact minimal implementation for the tmux reproduction, because delete role should not write code and the reported failure needs reproduction-focused TUI coverage rather than removal.

🤖 Structural solver proposes terminal-input phase fix

TL;DR

• What this is: Structural solver output for issue TUI composer wedges on tmux paste-buffer + immediate Enter: bracketed-paste state not exited before submit (codex-cli 0.139.0) #38, focused on the TUI tmux paste-buffer plus immediate Enter failure.
• Current state or conclusion: Propose a small terminal-input state machine so bracketed paste and its immediate Enter are normalized before composer submission logic sees them.
• What the maintainer should do OR what the controller does next: Controller can compare this with the other solver outputs and, if accepted, implement focused codex-tui regression coverage at the event-stream/composer boundary.

---

Structural framing

The failure is best treated as a terminal protocol normalization bug. TuiEventStream currently maps crossterm::event::Event::Paste into TuiEvent::Paste(String) and the next Enter into a normal TuiEvent::Key(Enter), so the composer can submit before the paste-adjacent newline is represented.

The proposed structure is a private TerminalInputPhase module under codex-rs/tui/src/tui/. It is a small state machine at the terminal event boundary: after a non-empty bracketed paste, the first plain Enter inside a short bounded window is emitted as paste-newline semantics instead of a submit-capable key. PasteBurst already applies the same principle for non-bracketed rapid key streams; this makes bracketed paste follow the same ownership model.

Key files and why they matter:

• codex-rs/tui/src/tui/event_stream.rs: owns crossterm-to-TuiEvent mapping, so it is the right boundary for terminal protocol timing.
• codex-rs/tui/src/tui.rs: defines TuiEvent, the internal semantic event consumed by App.
• codex-rs/tui/src/bottom_pane/chat_composer.rs: already has paste-burst Enter suppression, but it is too large and too deep in the stack to own tmux bracketed-paste protocol state.
• codex-rs/tui/src/chatwidget/tests/composer_submission.rs: existing focused submission tests can assert no Op::UserTurn is emitted until a later ordinary Enter.

Recommended implementation size: about +130 LOC / -5 LOC, with no schema, protocol, CLI, or dependency changes. Runtime cost is one small state field per TuiEventStream, one Instant::now() only on paste/plain-Enter events, and no new async hop.

verdict: propose

PROJECT_RULES clause violated (quoted verbatim)

FI-005 Boundaries take precedence over convenience; responsibility, layering, protocol, and state ownership must be clear, and shortcut layers must not bypass the main path.

FI-006 Changes must be verifiable and evidence-based; failures, gaps, and out-of-scope promises must be exposed explicitly, and tests must not be disabled to force a pass.

• Avoid large modules:
  • Prefer adding new modules instead of growing existing ones.
  • Target Rust modules under 500 LoC, excluding tests.
  • If a file exceeds roughly 800 LoC, add new functionality in a new module instead of extending
    the existing file unless there is a strong documented reason not to.
  • This rule applies especially to high-touch files that already attract unrelated changes, such
    as codex-rs/tui/src/app.rs, codex-rs/tui/src/bottom_pane/chat_composer.rs,
    codex-rs/tui/src/bottom_pane/footer.rs, codex-rs/tui/src/chatwidget.rs,
    codex-rs/tui/src/bottom_pane/mod.rs, and similarly central orchestration modules.
  • When extracting code from a large module, move the related tests and module/type docs toward
    the new implementation so the invariants stay close to the code that owns them.
  • Avoid adding new standalone methods to codex-rs/tui/src/chatwidget.rs unless the change is
    trivial; prefer new modules/files and keep chatwidget.rs focused on orchestration.

Reference-frame note: terminal input is a protocol decoder/state-machine problem; the known-good shape is to normalize ambiguous escape-sequence/key timing at the terminal event boundary, then expose a bounded semantic event to the editor/composer.

Recommended framing

把这个缺陷定义为“终端输入协议状态没有在边界层被完整建模”，而不是“Enter 提交逻辑偶发太快”。当前路径中 crossterm::event::Event::Paste 在 codex-rs/tui/src/tui/event_stream.rs 直接变成 TuiEvent::Paste(String)，紧接着的 KeyCode::Enter 又作为普通 TuiEvent::Key 进入 App 和 ChatComposer。非 bracketed paste 的 PasteBurst 已经有“粘贴窗口内 Enter 是换行而不是提交”的状态机，但 bracketed paste 没有等价的输入阶段语义。干净结构是在 TUI event-stream 层引入一个很小的 TerminalInputPhase，把“刚结束 bracketed paste 后的第一个无修饰 Enter”归一化为 paste-adjacent 输入，再让 composer 使用现有 handle_paste/newline 路径处理它。这样状态归属在协议边界，提交层只消费语义事件，不需要知道 tmux paste-buffer 的时序细节。

Concrete plan

• New abstractions (if any): TerminalInputPhase in Layer codex-tui terminal input, Project codex-rs/tui, file codex-rs/tui/src/tui/input_phase.rs. Interface: fn map(&mut self, event: crossterm::event::Event) -> Option<TuiEvent>; internally tracks AfterBracketedPaste { until: Instant }, emits TuiEvent::Paste(String) for paste payloads, and emits TuiEvent::Paste("\n".to_string()) or a new local TuiEvent::PasteTerminatorNewline for the first plain Enter inside a bounded post-paste window.
• Files:
  • codex-rs/tui/src/tui.rs: add mod input_phase;, extend TuiEvent only if choosing the explicit PasteTerminatorNewline variant; otherwise no enum growth.
  • codex-rs/tui/src/tui/event_stream.rs: add a TerminalInputPhase field to TuiEventStream, delegate map_crossterm_event through it, and keep focus/resize/job-control handling in this boundary. This file is 522 LoC, so adding ~25 LoC is acceptable but should be watched.
  • codex-rs/tui/src/tui/input_phase.rs: new private module, ~90 LoC including tests for paste followed by immediate Enter, paste followed by delayed Enter, and paste followed by modified Enter.
  • codex-rs/tui/src/app.rs: no behavioral special case; only map any new explicit TuiEvent variant to chat_widget.handle_paste("\n".to_string()) if the explicit-variant option is chosen.
  • codex-rs/tui/src/chatwidget/tests/composer_submission.rs: add one regression test that calls the public-ish widget path: chat.handle_paste("tmux text".to_string()); chat.handle_paste("\n".to_string()); or, if the explicit variant is threaded through App, use App::handle_tui_event with TuiEvent::Paste then the paste-adjacent newline. Assert no Op::UserTurn is submitted until a later ordinary Enter; then assert the submitted text is exactly tmux text\n or tmux text\n<next typed text> depending on the chosen reproducer.
  • Optional codex-rs/tui/src/tui/event_stream.rs tests: add one integration-style unit around FakeEventSource proving Event::Paste("x") then immediate Event::Key(Enter) yields TuiEvent::Paste("x") then paste-newline semantics instead of TuiEvent::Key(Enter).
• LOC delta: ~+130 / -5. Breakdown: input_phase.rs +90, event_stream.rs +25, tui.rs +5, tests +20, minimal deletion from old direct mapping.
• Tests to add:
  • codex-rs/tui/src/tui/input_phase.rs: plain_enter_immediately_after_bracketed_paste_is_paste_newline; asserts no submit-capable TuiEvent::Key(Enter) leaves the decoder while the post-paste window is active.
  • codex-rs/tui/src/tui/input_phase.rs: delayed_enter_after_bracketed_paste_stays_key; uses a window of about 120 ms, matching the existing paste-burst suppression window, to prove normal Enter submit remains reachable.
  • codex-rs/tui/src/chatwidget/tests/composer_submission.rs: tmux_paste_buffer_newline_then_enter_does_not_submit_until_after_paste_window; asserts paste text survives and the immediate newline is inserted, with assert_no_submit_op before the later ordinary Enter.
• Schema/protocol changes (if any): none. TuiEvent is crate-internal, not an app-server or CLI protocol.
• Governance/ruleset changes (if any): none. The plan follows the large-module rule by putting the new state machine in tui/input_phase.rs rather than extending chat_composer.rs or app.rs.
• Runtime cost: one extra small state field in each TuiEventStream (estimated 24-40 bytes), one Instant::now() only on Event::Paste and plain Enter events, zero new async hops, zero heap allocation except the existing paste payload and possibly a one-byte String for newline when mapping paste-adjacent Enter through TuiEvent::Paste.
• If the structural answer is issue decomposition, use the controller-private IssueDecompositionPlan boundary and child body artifacts; forbid solver/judge/worker GitHub lifecycle, public issue factories, and any wakeup_plan.py decompose action/projection.
• Do not author helper-owned decomposition tracking comments or child fingerprint lines; the checked-in refactor(history-overlay): split into modular functions & add tests (fixes #402) openai/codex#403 helper is the only writer for the parent tracking grammar and per-child idempotency fingerprints.

Risks

• This framing is slightly more code than changing handle_submission_with_time, but it prevents terminal protocol timing from leaking into every submit path and keeps chat_composer.rs from growing further past its current 11,188 LoC.
• The post-paste suppression window can be too long if set casually. Keep it equal to the existing PasteBurst Enter suppression window, or expose a single private constant in the new module, and prove delayed Enter still submits with a focused test.
• If crossterm already guarantees Event::Paste excludes the trailing Enter for all terminals except tmux, converting the next Enter to newline may surprise users who intentionally press Enter after paste very quickly. Bound the behavior to a short window and only plain KeyModifiers::NONE Enter after a non-empty paste payload.
• The issue acceptance text says "codex-apply-patch tests", but the actual source snapshot describes a TUI composer failure. I cannot verify an apply-patch-owned path from the current checkout evidence; the focused regression belongs in codex-tui. Treat the apply-patch wording as mirrored rubric noise unless a maintainer provides a concrete apply-patch reproducer.

Escalation triggers (if any)

• none

Reasoning trace (internal — for meta-judge)

• Why this structure beats a documented exception: The failure is caused by protocol/event ordering, not by domain-level submission semantics. A documented exception in handle_submission_with_time would force the composer to infer terminal state it does not own. A boundary decoder makes illegal ordering impossible for downstream consumers during the bounded post-paste phase.
• Why I picked this abstraction over alternatives: PasteBurst is already the right idea for non-bracketed paste, but it is composer-local and exists to classify raw character bursts. Bracketed paste is already classified by crossterm before the composer sees it, so the equivalent state belongs beside Event::Paste mapping in TuiEventStream. A new TerminalInputPhase has one caller today, but it is an explicit named extension point for terminal protocol normalization and keeps high-touch modules smaller.
• What I cannot decide alone: The exact timeout needs product tolerance. I recommend 120 ms because PasteBurst already uses that for Enter suppression, but maintainers may choose a smaller value if they think ultra-fast paste-then-submit should remain possible.

🤖 Minimal solver: current checkout already clears explicit paste state

TL;DR

• What this is: Minimal-change solver result for issue TUI composer wedges on tmux paste-buffer + immediate Enter: bracketed-paste state not exited before submit (codex-cli 0.139.0) #38.
• Current state or conclusion: I classify this as current-checkout false-positive for the explicit bracketed-paste path because handle_paste clears paste-burst state before immediate Enter submission is evaluated.
• What the maintainer should do OR what the controller does next: Treat this as no-code unless a fresh tmux-level reproducer shows current checkout emits events that bypass Event::Paste.

---

Verification notes

I checked the TUI input ownership boundary, not codex-apply-patch, because the reported failure is composer input handling. codex-apply-patch is the patch parser/tool crate; it does not own terminal paste state.

codex-rs/tui/src/tui/event_stream.rs:248 maps crossterm Event::Paste(pasted) into TuiEvent::Paste(pasted). This matters because bracketed paste should enter the composer through the explicit paste path rather than as ordinary Enter key handling.

codex-rs/tui/src/bottom_pane/chat_composer.rs:883 is the composer paste integration method. It normalizes and inserts the paste, then codex-rs/tui/src/bottom_pane/chat_composer.rs:898 calls clear_after_explicit_paste(), which clears the transient paste-burst Enter-suppression state.

codex-rs/tui/src/bottom_pane/chat_composer.rs:2814 and codex-rs/tui/src/bottom_pane/chat_composer.rs:2823 are the Enter-suppression checks. They only treat Enter as paste continuation when the paste-burst state or suppression window remains active. The explicit paste path clears that state before immediate Enter can reach these branches.

Existing focused coverage already checks the essential behavior: codex-rs/tui/src/bottom_pane/chat_composer.rs:7454 defines handle_paste_small_inserts_text, which pastes text and then presses Enter; the expected result is InputResult::Submitted with the pasted text. I ran:

just test -p codex-tui handle_paste_small_inserts_text

Result: 1 test run, 1 passed, 2837 skipped.

Option	Trade-off
No-code false-positive for current checkout	Matches source and passing focused test for explicit bracketed paste.
Add a new TUI composer regression anyway	Possible protective coverage, but duplicates existing behavior unless a new failing event ordering is supplied.
Add codex-apply-patch coverage	Wrong ownership boundary; it would not exercise TUI paste state.

## Recommended framing
最小变更结论是 current-checkout false-positive，而不是实现补丁：当前 TUI 事件流把 bracketed paste 映射为 `TuiEvent::Paste`，composer 的 `handle_paste` 已经在插入显式 paste 内容后调用 `clear_after_explicit_paste()`，因此后续立即按 Enter 时，`handle_submission_with_time` 中只有在 `paste_burst` 仍 active 或 Enter-suppression window 仍 active 时才会把 Enter 当作 paste 内换行的分支不会触发。已有 focused composer 测试 `handle_paste_small_inserts_text` 覆盖“显式 paste 后 Enter 提交可见文本”并在当前 checkout 通过。`codex-apply-patch` 没有 TUI composer/bracketed-paste 所有权，所以把回归测试放到 apply-patch 会错放边界。

## Concrete plan
- Files: none. No source edit is justified because the suspected explicit bracketed-paste state leak is already cleared in `codex-rs/tui/src/bottom_pane/chat_composer.rs`.
- LOC delta: ~+0 / -0
- Tests to add/modify: none now. Existing focused coverage is `codex-rs/tui/src/bottom_pane/chat_composer.rs::handle_paste_small_inserts_text`; if a fresh tmux-level reproducer still fails, add a nearby regression in the same composer test module or an integration-style TUI input test that models `TuiEvent::Paste(text)` followed by `KeyCode::Enter`. Do not add `codex-apply-patch` tests unless a separate apply-patch parser/tool failure is shown.
- Governance/ruleset change (if any): none.
- Migration path: no migration needed.

## Risks
- Source inspection and the focused unit test verify the repo-owned explicit paste path, not a live tmux PTY session with `tmux paste-buffer`.
- A tmux/crossterm ordering bug could still exist if the terminal reports paste data as plain key bursts rather than `Event::Paste`; that would require a new reproducer showing current-checkout event ordering.
- The issue acceptance text asks for `codex-apply-patch` tests, but the cited failure is TUI composer input handling; following that test path would create non-load-bearing coverage.

## Escalation triggers (if any)
- none

## Reasoning trace (internal — short, for meta-judge)
- Reference-frame note: terminal input state machines should clear transient mode flags at explicit delimiter boundaries; bracketed paste end is such a delimiter, and regression coverage should sit at the owner boundary that consumes the terminal event.
- Why this is the minimum: `codex-rs/tui/src/tui/event_stream.rs:248` maps crossterm `Event::Paste(pasted)` to `TuiEvent::Paste(pasted)`. `codex-rs/tui/src/bottom_pane/chat_composer.rs:883-899` normalizes/inserts explicit paste text and clears `paste_burst` state. `codex-rs/tui/src/bottom_pane/chat_composer.rs:2814-2832` only converts Enter into a newline when `paste_burst` is still active or the suppression window is still active. The clearing at line 898 prevents the suspected wedge path for explicit bracketed paste.
- What I considered but rejected: adding a minimal `clear_after_explicit_paste()` call, because it already exists; adding apply-patch coverage, because apply-patch has no TUI input state; adding a new protective composer test, because the existing test at `codex-rs/tui/src/bottom_pane/chat_composer.rs:7451-7479` already checks explicit paste followed by Enter submits.
- What I cannot decide alone: whether an external tmux/crossterm path on a specific terminal emits events in a way that bypasses `Event::Paste` in the current checkout.
- Verification run: `just test -p codex-tui handle_paste_small_inserts_text` passed with 1 test run, 1 passed, 2837 skipped.

---

Arbitration Result

I classified the solver outputs as minimal=false-positive, structural=propose, and delete=abstain. The governing rule says a false-positive claim must be verified by re-reading the current evidence before accepting it. I verified the claim against the current checkout and reran the focused test.

codex-rs/tui/src/tui/event_stream.rs:248 maps crossterm Event::Paste(pasted) to TuiEvent::Paste(pasted). This matters because explicit bracketed paste reaches the app as a paste event, not as normal Enter key input.

codex-rs/tui/src/bottom_pane/chat_composer.rs:883 integrates explicit paste text. At chat_composer.rs:898, it calls clear_after_explicit_paste(), which clears paste-burst Enter suppression before a later user Enter is evaluated.

codex-rs/tui/src/bottom_pane/chat_composer.rs:2814 and chat_composer.rs:2823 only turn Enter into paste-newline behavior when paste-burst state or its suppression window is still active. The explicit paste path clears that state first.

codex-rs/tui/src/bottom_pane/chat_composer.rs:7454 defines the focused regression handle_paste_small_inserts_text, which pastes text and then presses Enter; the expected result is InputResult::Submitted with the pasted text. I reran it in the current checkout:

just test -p codex-tui handle_paste_small_inserts_text

Result: 1 test run, 1 passed, 2837 skipped.

Option	Decision	Trade-off
Triage false-positive	Selected	Matches current source and focused test for the explicit bracketed-paste path.
Dispatch structural implementation	Rejected for this round	Only one implementation-bearing solver proposed it, and it would change the verified paste-then-Enter submit behavior.
Delete/collapse paste handling	Rejected	Delete solver found the paste paths are active user-facing TUI behavior.
Add codex-apply-patch tests	Rejected	The verified ownership boundary is codex-tui, not the patch parser/tool crate.

New evidence needed before reopening: a current-checkout tmux/crossterm event trace or failing TUI test showing tmux paste-buffer plus immediate Enter still bypasses the verified Event::Paste -> handle_paste -> clear_after_explicit_paste() path.

## Decision
判定为 triage-only false-positive，不授权实现分发。参考框架：终端输入状态机应在明确的协议边界退出临时状态，回归验证应落在拥有该状态的 TUI 输入/编辑器边界。三份 solver 中，minimal 声称 current checkout 已清除显式 bracketed paste 的 transient state；我重新读取当前代码并运行 focused test 后确认该说法成立：`handle_paste` 在插入显式 paste 后调用 `clear_after_explicit_paste()`，随后普通 Enter 不会再被 paste-burst suppression 捕获。structural 的 `TerminalInputPhase` 方案是一个未达成共识的实现提案，并且会改变已验证的 explicit paste 后 Enter 提交语义；delete 的 abstain 只证明不应删除 paste 处理路径，不构成实现共识。因此本轮只能记录 no-source-change triage，而不是自动实施结构性改动。

## If triage-only consensus
- Resolution: false-positive
- Canonical key: openai/codex#28167
- Existing issue/PR/branch/commit evidence: local managed issue `ChronoAIProject/codex#38`; no PR/branch/commit evidence for an implementation fix was found or required in this round.
- New evidence required before reopening: provide a current-checkout tmux/crossterm event trace or failing TUI test showing `tmux paste-buffer` plus immediate Enter still bypasses the verified `Event::Paste` -> `handle_paste` -> `clear_after_explicit_paste()` path.
