🤖 Delete solver abstains on removing the subagent status dot

TL;DR

• What this is: delete-role design review for issue /subagents active status dot is nearly indistinguishable in Ghostty default dark theme #27.
• Current state or conclusion: the /subagents status dot is a load-bearing open/closed picker affordance, so deletion is not the right fix.
• What the maintainer should do OR what the controller does next: controller should let the minimal or structural solver pursue a bounded contrast fix with focused TUI regression coverage.

Delete-role finding

I traced the status dot to agent_picker_status_dot_spans, the helper that builds the prefix glyph for rows in the /subagents picker. That helper has one direct caller in open_agent_picker, where it is assigned to SelectionItem.name_prefix_spans; this matters because deleting it would remove the only compact visual signal that separates open/live entries from closed entries in that list.

The commit history also points away from deletion: the dot was introduced with the feature that keeps closed agents visible in the picker, and a later contrast-focused change adjusted the closed-agent styling. That makes this a small accessibility/contrast bug in an existing affordance, not dead code or an orphan feature.

Option	Trade-off
Delete the dot	Removes the low-contrast active glyph, but also removes the picker state cue.
Keep the dot and fix contrast	Preserves state semantics while addressing Ghostty dark-theme readability.
Replace with a broader picker redesign	More review surface than the issue needs.

Recommended controller path: choose a minimal implementation that changes the active/open dot styling in codex-rs/tui/src/multi_agents.rs and adds focused TUI regression coverage for the picker rendering. The issue text mentions codex-apply-patch tests, but the bounded code path I found is in codex-tui, so the implementation solver should verify the intended test crate before landing.

## Classification
e) Genuinely needed and right-sized; no current deletion/collapse is justified.

## Reference-frame note
Applicable frame: accessibility contrast and affordance preservation in terminal UI. A state indicator that distinguishes active/open from closed entries should be made perceivable across supported themes, not deleted, when it is the only compact state affordance in that control.

## Recommended action
不要删除 `/subagents` 选择器的状态点。`agent_picker_status_dot_spans` 只有一个直接调用点，但它是选择器行名前缀的唯一 open/closed 状态提示；删除会让 closed agent 和 active/open agent 在列表中更难区分。这个问题应交给 minimal/structural 路径做小修：在 `codex-rs/tui/src/multi_agents.rs` 中调整 active/open dot 的样式，使它在 Ghostty 默认 dark theme 下可辨认，并补一条聚焦的 TUI regression/snapshot 覆盖。

## 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

## Reverse-evidence (why this is safe to delete)
- Not safe to delete: `codex-rs/tui/src/app/session_lifecycle.rs:117` passes `agent_picker_status_dot_spans(entry.is_closed)` into `SelectionItem.name_prefix_spans`, making this the rendered status prefix for the `/subagents` picker.
- Not safe to delete: `codex-rs/tui/src/multi_agents.rs:75` centralizes the status-dot styling and currently maps closed threads to the default foreground and open threads to green.
- Not safe to delete: `codex-rs/tui/src/multi_agents.rs:41` and `codex-rs/tui/src/multi_agents.rs:43` define separate running and closed state on `AgentPickerThreadEntry`; the picker prefix uses the closed state as a compact visibility cue.
- Git history shows the dot was introduced by `829d1080f641197c3ce8351c3e9951dccc3636c6` ("feat: keep dead agents in the agent picker") with closed/open visual distinction, then changed by `9685e7d6d1304c0065afe437046275a346b896c1` ("Improve subagent contrast in TUI") to avoid low-contrast closed dots. That history supports preserving the affordance and fixing contrast, not removing the indicator.
- Public API break risk is low for a style change, but deletion would remove a user-facing TUI signal. `rg` found one direct caller, which means the fix can stay bounded without deleting the helper.
- External repo dependency was not checked; this delete-solver pass did not touch `$EXTERNAL_REPOS`.
- Tests covering picker state are load-bearing for navigation semantics: existing tests around `open_agent_picker_*` assert cached, missing, closed, and loaded thread state behavior. They do not make the status-dot helper dead.

## Risks
- The issue snapshot did not include a screenshot or exact Ghostty color sample, so the precise contrast target still needs visual or snapshot-backed confirmation by the implementation solver.
- If design intent has changed and `/subagents` should no longer show any state glyph, that would be a product decision not evidenced by the current issue or code history.
- The issue body says "Add focused regression coverage in codex-apply-patch tests", which does not match the bounded TUI module found here. The implementation path should validate the intended test crate before landing.

## Escalation triggers (if any)
- none

## Reasoning trace (internal - for meta-judge)
- Why I claim this can be deleted: I do not claim it can be deleted. The observed code is a small, single-purpose TUI affordance, not dead code or an orphan feature.
- What I checked to verify safety: searched for subagent/status/dot rendering; found `agent_picker_status_dot_spans` in `codex-rs/tui/src/multi_agents.rs`; found its only direct caller in `codex-rs/tui/src/app/session_lifecycle.rs`; inspected picker-state tests in `codex-rs/tui/src/app/tests.rs`; checked `git log --oneline` and `git log -p --follow -S` for the status-dot helper and contrast changes.
- What I cannot decide alone: the exact replacement color/glyph/style that best satisfies Ghostty default dark theme contrast, because this role forbids code changes and the issue snapshot has no screenshot or color measurement.

🤖 Minimal solver proposes a one-helper TUI contrast fix

TL;DR

• What this is: Minimal-change design solver output for issue /subagents active status dot is nearly indistinguishable in Ghostty default dark theme #27.
• Current state or conclusion: The reproduced path is the codex-tui Subagents picker status-prefix helper, not codex-apply-patch rendering.
• What the controller does next: Use this as one consensus input for selecting the implementation plan.

---

Minimal framing

The current checkout renders /agent Subagents picker row prefixes through agent_picker_status_dot_spans in codex-rs/tui/src/multi_agents.rs; open_agent_picker in codex-rs/tui/src/app/session_lifecycle.rs passes those spans directly into the selection rows. The open/non-closed marker is currently a small plain green bullet, which is plausibly low contrast in Ghostty's default dark palette.

Minimal plan: keep the existing picker state model and navigation behavior, but make the non-closed marker carry contrast through shape and weight, for example ● plus green plus bold, while keeping closed threads visibly de-emphasized with a dim bullet. Add one focused codex-tui regression test for the helper's open and closed marker content/style, then run just fmt and just test -p codex-tui.

Option	Trade-off
One-helper glyph/style fix	Smallest change; improves visibility without terminal-specific logic.
Ghostty-specific palette handling	Larger and brittle; unnecessary for a status marker.
New active/running/closed state model	More expressive, but broader than the reported contrast bug.

## Recommended framing
当前 checkout 中问题仍可定位到 TUI 的 subagent picker：`codex-rs/tui/src/multi_agents.rs` 的 `agent_picker_status_dot_spans` 对未关闭线程只渲染普通 `"•".green()`，而 `codex-rs/tui/src/app/session_lifecycle.rs` 在 `/agent` 打开的 `Subagents` 选择器中直接使用这个前缀；在 Ghostty 默认暗色主题下，普通 ANSI green 小圆点容易被背景吃掉。最小可行修复是不改线程状态模型、不引入主题探测，只把“可用/活跃”圆点改成更高对比的同语义标记，例如 `"●".green().bold()`，并让关闭线程继续用低强调的 `"•".dim()`；这样只调整可见 affordance，不改变排序、选择、liveness 刷新或 app-server 行为。

## Concrete plan
- Files:
  - `codex-rs/tui/src/multi_agents.rs`: change `agent_picker_status_dot_spans` so the non-closed status marker uses a larger/bolder glyph and closed marker is explicitly dimmed; add a focused unit test that asserts glyph and style for open vs closed picker dots.
  - `codex-rs/tui/src/app/tests.rs` or existing app snapshot coverage: if picker row snapshots expose prefix styling, update/add one focused snapshot; otherwise keep the regression in `multi_agents.rs` because the helper owns the visual contract.
- LOC delta: ~+18 / -2.
- Tests to add/modify:
  - Add one focused `codex-tui` unit test for `agent_picker_status_dot_spans`, checking open marker content/style and closed marker content/style.
  - Run `just fmt`, then `just test -p codex-tui`; if an existing snapshot changes, inspect and accept the intended `codex-tui` snapshot update.
- Governance/ruleset change (if any): none.
- Migration path: no migration needed.

## Risks
- ANSI green itself remains terminal-theme dependent; bold plus a filled marker improves contrast without adding terminal-specific palette logic.
- The issue text mentions `codex-apply-patch` tests, but the verified code path is `codex-tui`; forcing apply-patch coverage would miss the user-visible bug.
- If maintainers want active-running and merely-open agents to use different markers, that is a broader state-design change than the minimal contrast fix.

## Escalation triggers (if any)
- none

## Reasoning trace (internal — short, for meta-judge)
- Reference-frame note: accessibility affordance principle for status indicators in terminal UI: keep semantic state visible with shape/weight as well as color, because terminal palettes vary.
- Why this is the minimum: the issue maps to one status-prefix helper used by the Subagents picker; changing the glyph/style there fixes every picker row without changing navigation or backend state.
- What I considered but rejected: Ghostty-specific terminal detection and palette overrides, because they would be larger and brittle; adding a new enum for active/running/closed, because the current issue only reports dot contrast; apply-patch tests, because no apply-patch rendering path is involved.
- What I cannot decide alone: whether maintainers prefer `●` or keeping `•` with `.bold()`, but both fit the same one-helper plan.

🤖 Structural solver proposes TUI status-color fix for /subagents dot

TL;DR

• What this is: structural solver output for issue /subagents active status dot is nearly indistinguishable in Ghostty default dark theme #27, focused on the /subagents active status dot.
• Current state or conclusion: the verified TUI path renders the open agent dot green, while the repo style guide says status indicators use ANSI cyan.
• What the controller does next: compare this with the other solver outputs and, if accepted, implement the small codex-tui rendering fix plus focused regression coverage.

---

Structural framing

The bounded source path is TUI rendering, not apply-patch behavior. agent_picker_status_dot_spans is the helper that builds the bullet prefix for /subagents; it currently colors every non-closed dot green. open_agent_picker passes those spans into the selection row prefix, so the visible active/open dot inherits that green rendering.

The clean fix is to treat the dot as a status indicator and render the open marker with ANSI cyan, following codex-rs/tui/styles.md. Closed entries should keep the default foreground so they remain lower-emphasis without adding terminal-specific Ghostty logic or custom colors.

Option	Trade-off
Minimal color fix	Change "•".green() to "•".cyan() and add direct span-style regression tests; lowest review cost.
Tiny semantic enum	Replace the boolean helper input with a private AgentPickerStatusIndicator enum before applying cyan; clearer callsite semantics but more code for one verified caller.

Recommended implementation scope: touch codex-rs/tui/src/multi_agents.rs, optionally codex-rs/tui/src/app/session_lifecycle.rs if the helper signature changes, and add codex-tui tests proving open dots use Color::Cyan while closed dots remain default foreground. There are no schema, protocol, app-server, CLI, config, or resume compatibility changes.

## PROJECT_RULES clause violated (quoted verbatim)
> - **User input tips, selection, and status indicators:** Use ANSI `cyan`.

Supporting rule for the required coverage:

> **Requirement:** any change that affects user-visible UI (including adding new UI) must include
> corresponding `insta` snapshot coverage (add a new snapshot test if one doesn't exist yet, or
> update the existing snapshot). Review and accept snapshot updates as part of the PR so UI impact
> is easy to review and future diffs stay visual.

## Recommended framing
The bug is a semantic-color mismatch in the TUI `/subagents` picker: `codex-rs/tui/src/app/session_lifecycle.rs:117` injects the prefix spans returned by `agent_picker_status_dot_spans`, and `codex-rs/tui/src/multi_agents.rs:75` currently renders every non-closed status dot as green. The repo style contract reserves green for success/addition states and cyan for status indicators, so the clean structural fix is to make the agent picker dot a status indicator by construction. Keep the behavior local to `codex-rs/tui/src/multi_agents.rs`, give the helper a semantic input shape instead of a bare closed/open color branch if touching the signature, and cover the rendered span styles in TUI tests. Reference-frame note: terminal UI semantic-color token discipline and contrast-safe ANSI palette usage.

## Concrete plan
- New abstractions (if any): Prefer no reusable cross-module abstraction. If changing the helper signature, add a private `AgentPickerStatusIndicator` enum in Layer TUI / Project `codex-tui` / `codex-rs/tui/src/multi_agents.rs` with variants `Open` and `Closed`; it replaces the ambiguous bool at the presentation boundary and is justified as the named extension point for picker status markers. Do not add a new crate or a shared theme system.
- Files:
  - `codex-rs/tui/src/multi_agents.rs`: change the open/non-closed bullet from `"•".green()` to `"•".cyan()` or route through `AgentPickerStatusIndicator::Open`; keep the closed bullet as default foreground plus trailing space. If adding the enum, expose only the small constructor/helper needed by `session_lifecycle.rs`.
  - `codex-rs/tui/src/app/session_lifecycle.rs`: only update the callsite if the helper signature changes; otherwise no edit.
  - `codex-rs/tui/src/app/tests.rs` or `codex-rs/tui/src/multi_agents.rs` tests: add focused regression coverage for the prefix spans, checking the whole span vector when practical rather than inspecting unrelated fields one by one.
  - `codex-rs/tui/src/snapshots/...`: update or add the relevant `insta` snapshot if the rendered `/subagents` picker output captures styles; if the existing snapshot normalizes styles away, add a direct style assertion test and a minimal snapshot that preserves ANSI/style data.
- LOC delta: ~+18 / -1 for the minimal color-only fix with direct test coverage; ~+35 / -3 if replacing the bool parameter with a private enum.
- Tests to add:
  - `codex-rs/tui/src/multi_agents.rs`: `agent_picker_status_dot_spans_uses_cyan_for_open_status_indicator` asserts the open marker renders `•` with `Color::Cyan` and the spacer remains unstyled.
  - `codex-rs/tui/src/multi_agents.rs`: `agent_picker_status_dot_spans_keeps_closed_marker_default` asserts the closed marker renders `•` with no foreground color, so closed threads remain visually de-emphasized by absence of status color.
  - If picker rendering already has an ANSI-preserving snapshot hook, add or update one `/subagents` picker snapshot showing one open and one closed thread; otherwise avoid a broad app snapshot churn and keep the focused span-style test.
- Schema/protocol changes (if any): none; this is local TUI rendering only and has no app-server, CLI, config, resume, or protocol compatibility impact.
- Governance/ruleset changes (if any): none. The current style guide already contains the needed invariant; the implementation should conform to it.
- Runtime cost: 0 latency hops; 0 additional async work; same two `Span` allocations in the minimal fix; if an enum is introduced, it is a `Copy` value with no heap allocation and no measurable render-time cost.
- 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 #403 helper is the only writer for the parent tracking grammar and per-child idempotency fingerprints.

## Risks
- The issue body's acceptance criteria mention `codex-apply-patch` tests, but the verified source surface is `codex-tui`: `/subagents` is dispatched through `AppEvent::OpenAgentPicker`, rendered by `session_lifecycle.rs`, and styled by `multi_agents.rs`. Adding apply-patch tests would not exercise this UI regression.
- A private enum may be cleaner than a bool, but for a one-callsite one-character color fix it can be over-engineering. Keep the implementation bounded: no theme registry, no terminal-specific Ghostty branch, no custom RGB color, and no broader picker refactor.

## Escalation triggers (if any)
- none

## Reasoning trace (internal — for meta-judge)
- Evidence verified: `codex-rs/tui/src/multi_agents.rs:75` returns a green `•` for every non-closed agent picker status dot; `codex-rs/tui/src/app/session_lifecycle.rs:117` passes that prefix into `/subagents` selection items; `codex-rs/tui/styles.md` states status indicators use ANSI cyan.
- Why this structure beats a documented exception: the rule already names the correct semantic color, so documenting Ghostty as an exception would preserve the contrast bug and add terminal-specific policy where a single semantic-token correction solves it.
- Why I picked this abstraction over alternatives: a local status-indicator helper or tiny private enum keeps status marker semantics at the presentation boundary. A global theme abstraction is unjustified because there is one verified caller and no evidence of a broader palette-system failure.
- What I cannot decide alone: whether maintainers prefer the minimal one-line color change or the bool-to-enum cleanup in the same PR. Both satisfy the issue; the minimal change has lower review risk.
- Verification plan: run `just fmt` in `codex-rs`; run `just test -p codex-tui`; if snapshots are affected, inspect pending `*.snap.new` files and accept only the intentional TUI snapshot changes.

🤖 Meta-judge requests one convergence round for issue 27

TL;DR

• What this is: Round 1 meta-judge arbitration for the /subagents active status dot contrast issue.
• Current state or conclusion: No implementation dispatch is authorized yet because the two implementation proposals disagree on the exact dot style.
• What the controller does next: Run round 2 with a narrowed question about cyan semantic status color versus a bold/larger green marker, plus the closed-dot style and focused codex-tui coverage.

---

Arbitration result

The three solver artifacts were present for issue 27, round 1, and their frontmatter matched the expected roles. The delete solver abstained with evidence that the status dot is a load-bearing picker affordance, so deletion is not the right fix. That abstain is compatible-neutral for this manual issue because the two implementation solvers both keep the scope in the TUI picker path.

The blocker is the exact visual contract. The minimal solver proposes a larger/bold green open marker and dim closed marker. The structural solver proposes ANSI cyan for the open status indicator under codex-rs/tui/styles.md, with the closed marker using default/no foreground. Those are contradictory choices on the user-visible style, so round 1 does not meet the implementation-bearing consensus gate.

Option	Proposed by	Trade-off
Larger/bold green marker	minimal	Small, directly raises contrast, but may conflict with the TUI style rule that status indicators use cyan.
ANSI cyan status indicator	structural	Aligns with the TUI style guide, but round 2 should confirm whether it is enough for Ghostty default dark contrast.
Delete the marker	delete solver rejected	Removes the open/closed affordance and is not supported by the verified callsite/history evidence.

Round 2 should answer one question: should the /subagents open/active dot use semantic ANSI cyan or a larger/bold green marker, and what exact open/closed glyph plus style should tests enforce?

## Decision
结论是进入第 2 轮收敛，而不是授权实现。三个输入路径、issue 编号、round 编号和角色均匹配 issue 27 / round 1，delete solver 的 `abstain` 在 `manual-issue (prompt-only provenance)` + `gh-issue-27` 的 Path A 语境下可以作为兼容中立信号，因为它证明状态点不是可删除目标并明确支持做对比度修复；但两个实现型 solver 只在边界上相同，尚未在关键实现选择上达成一致：minimal 选择更大/加粗的 green active marker，并倾向 closed marker dim；structural 选择遵循 TUI style guide 的 cyan status indicator，并保持 closed marker default/no foreground。因此这不是 implementation-bearing consensus，下一轮必须只回答状态点的精确视觉 contract。

Reference-frame note: accessibility affordance design for terminal UI plus semantic color-token consistency. A status indicator should remain perceivable across terminal themes, and repo-local style tokens should be followed unless the solvers explicitly justify a bounded exception.

## If converge
- Convergence question (specific): Should the `/subagents` open/active status dot be fixed by semantic ANSI cyan using the existing TUI status-indicator rule, or by a larger/bold green marker, and what exact open/closed glyph + style contract should implementation test?
- What each solver should address explicitly:
  - State the exact active/open marker glyph and style, including foreground color and weight.
  - State the exact closed marker glyph and style, including whether it remains default/no foreground or becomes dim.
  - Explain whether `codex-rs/tui/styles.md` line-level guidance for "status indicators use ANSI cyan" controls this UI, or why a green exception is justified.
  - Keep or reject a private enum/signature change for `agent_picker_status_dot_spans`; if rejected, keep the bool helper and explain why this positional bool is acceptable or already self-documenting at the callsite.
  - Confirm the implementation-bearing `scope_paths` and focused tests, especially whether direct `codex-tui` span-style coverage is sufficient when the issue text mentions `codex-apply-patch` tests.
- Round number this fires: 2; marker payload uses source round `1`
- Progress since prior round: issue was localized to `codex-rs/tui/src/multi_agents.rs` and `codex-rs/tui/src/app/session_lifecycle.rs`; deletion was ruled out with callsite and git-history evidence; both implementation solvers agreed no governance, protocol, config, app-server, or migration changes are needed.

🤖 Minimal solver selects cyan for the /subagents status dot

TL;DR

• What this is: Round 2 minimal-change solver output for issue /subagents active status dot is nearly indistinguishable in Ghostty default dark theme #27.
• Current state or conclusion: The smallest fix is to change the open /subagents status dot from green to ANSI cyan while keeping the same glyph and closed-dot default styling.
• What the controller does next: Compare this with the other round 2 solver outputs and, if consensus holds, dispatch the bounded codex-tui implementation plus focused regression coverage.

---

Minimal framing

The verified path is TUI picker rendering. agent_picker_status_dot_spans is the helper that builds the row prefix for agent picker entries; at codex-rs/tui/src/multi_agents.rs:75 it currently returns a green • for non-closed agents. SelectionItem.name_prefix_spans is the picker field that displays that prefix; at codex-rs/tui/src/app/session_lifecycle.rs:117 the Subagents picker passes the helper output straight through, so this helper owns the visible status dot.

The project style rule points to cyan, not green. codex-rs/tui/styles.md:10 says user input tips, selection, and status indicators use ANSI cyan, while codex-rs/tui/styles.md:11 reserves ANSI green for success and additions. The minimal contract should therefore be: open/non-closed marker is • with cyan foreground; closed marker remains • with default foreground; the trailing space remains unchanged.

Option	Minimal solver choice	Trade-off
•.cyan() for open, default • for closed	Yes	One-token visual fix, matches the TUI style rule, preserves row width and behavior.
Larger or bold green marker	No	May improve visibility, but keeps the status indicator on the success color token and changes visual weight.
New enum or three-state status model	No	Could clarify future running/open/closed states, but adds API surface beyond the verified contrast bug.

Recommended implementation scope: touch only codex-rs/tui/src/multi_agents.rs, change the open branch from .green() to .cyan(), and add one focused codex-tui test for the helper's open and closed returned spans.

## Recommended framing
最小可行边界是把 `/subagents` picker 的 open/non-closed 状态点从 green success 语义改为 TUI 规则中的 cyan status-indicator 语义，并保持同一个 `•` glyph 与 closed 默认前景不变。当前证据在 `codex-rs/tui/src/multi_agents.rs:75` 到 `codex-rs/tui/src/multi_agents.rs:81`：`agent_picker_status_dot_spans(false)` 返回 `"•".green()`；`codex-rs/tui/src/app/session_lifecycle.rs:117` 直接把这些 spans 作为 `SelectionItem.name_prefix_spans` 渲染到 `Subagents` picker；`codex-rs/tui/styles.md:10` 明确规定 status indicators 使用 ANSI `cyan`，而 `codex-rs/tui/styles.md:11` 把 green 留给 success/additions。reference-frame note: terminal UI semantic color-token discipline plus accessibility affordance preservation; status indicators should use the shared semantic color token instead of a success color unless there is a documented exception.

## Concrete plan
- Files:
  - `codex-rs/tui/src/multi_agents.rs`: change the non-closed branch in `agent_picker_status_dot_spans` from `"•".green()` to `"•".cyan()`. Keep the closed branch as `"•".into()` and the trailing space unchanged so layout, row search, and picker behavior do not move.
  - `codex-rs/tui/src/multi_agents.rs`: add one focused test in the existing inline `mod tests` asserting the full returned `Vec<Span<'static>>` for open and closed dots, including glyph content, trailing space, open foreground `Some(Color::Cyan)`, closed foreground `None`, and no unexpected bold/dim modifier. This is the smallest regression because the helper owns the rendered prefix contract.
- LOC delta: ~+18 / -1.
- Tests to add/modify:
  - Add one `codex-tui` unit test in `codex-rs/tui/src/multi_agents.rs`; use existing `pretty_assertions::assert_eq`, `Color`, and `Modifier` imports already present in the module.
  - Run `just fmt` in `codex-rs` after edits.
  - Run `just test -p codex-tui` because the changed crate is `codex-tui`.
  - Run `just fix -p codex-tui` before finalizing if this becomes a large implementation change; for the proposed one-line style fix it is still acceptable and scoped if the implementer wants local Clippy confirmation.
- Governance/ruleset change (if any): none. The plan follows the existing `codex-rs/tui/styles.md` rule instead of changing it.
- Migration path: no migration needed.

## Risks
- ANSI cyan is still terminal-theme dependent, but it is the repo's chosen status-indicator token and avoids custom colors that `styles.md` discourages.
- Keeping the same `•` glyph means the fix relies on semantic color contrast rather than a larger shape; that is the narrowest change and preserves row width exactly.
- The issue snapshot mentions `codex-apply-patch` tests, but verified source evidence is in `codex-tui`; adding apply-patch coverage would not exercise the visible `/subagents` picker bug.

## Escalation triggers (if any)
- none

## Reasoning trace (internal — short, for meta-judge)
- Why this is the minimum: one styling token in one helper controls the affected picker prefix; the direct caller passes it through without transforming it.
- What I considered but rejected: a larger/bold green dot because it preserves the wrong success color semantics and changes glyph metrics; a private enum because there is one boolean caller and the issue is a visual token bug, not an API ambiguity; dimming closed dots because that would add a second behavior change not required to fix the reported active-dot contrast.
- What I cannot decide alone: whether maintainers want a future three-state indicator for running vs merely open agents; that is outside this minimal fix.

🤖 Delete solver abstains on removing the /subagents status dot

TL;DR

• What this is: Round 2 delete-role design review for issue /subagents active status dot is nearly indistinguishable in Ghostty default dark theme #27.
• Current state or conclusion: the status dot is a load-bearing open/closed picker affordance, so deletion is not justified.
• What the controller does next: pick an implementation plan that keeps the marker and applies a focused codex-tui style regression.

---

Delete-role finding

I traced the visible marker through the TUI picker path. agent_picker_status_dot_spans is the helper that builds the prefix glyph, and open_agent_picker passes it into SelectionItem.name_prefix_spans, which is rendered as part of each selection row. That makes the marker a real user-facing state cue rather than dead code.

The history points the same way: the helper was introduced with the change that kept closed agents visible in the picker. Removing it would erase the compact distinction between open/non-closed and closed entries instead of fixing the contrast report.

Option	Trade-off
Delete the dot	Removes the low-contrast glyph, but also removes the only inline open/closed cue I found in the picker row.
Keep the dot and use ANSI cyan	Preserves the affordance and follows codex-rs/tui/styles.md, which assigns cyan to status indicators.
Use a larger/bold green marker	May improve visibility, but creates a one-off exception to the local TUI status-color rule.

Recommended controller path: do not delete the helper or glyph. Let the implementation-bearing solver keep the marker, change the open/non-closed status indicator toward the existing ANSI cyan style contract, and add focused codex-tui regression coverage for the open and closed marker rendering.

solver: delete
issue: 27
cluster: issue-27
verdict: abstain
---

## Classification
e) Genuinely needed and right-sized; no current deletion/collapse is justified.

## Recommended action
Abstain from deleting the `/subagents` status dot. The dot is the compact state affordance for the picker row prefix: `open_agent_picker` passes `agent_picker_status_dot_spans(entry.is_closed)` into `SelectionItem.name_prefix_spans`, and the selection popup renderer preserves that prefix in the user-visible row. Deleting the helper or the glyph would remove the only inline open/closed cue that was added when closed agents became visible in the picker. The implementation-bearing path should keep the marker and resolve round 2 in favor of the repo-local TUI style contract: use the existing status-indicator color rule, ANSI cyan, for open/non-closed entries, and keep closed entries lower-emphasis without introducing a larger/bold green exception.

## 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
- If deletion is unsafe because the issue is merely too large, you may propose a bounded `IssueDecompositionPlan` artifact path instead of deletion; do not propose direct GitHub lifecycle calls, public issue factories, or any `wakeup_plan.py` decompose action/projection.
- Do not author helper-owned decomposition tracking comments or child fingerprint lines; the checked-in #403 helper is the only writer for the parent tracking grammar and per-child idempotency fingerprints.

## Reverse-evidence (why this is safe to delete)
- Not safe to delete: `codex-rs/tui/src/app/session_lifecycle.rs:117` assigns `agent_picker_status_dot_spans(entry.is_closed)` to `SelectionItem.name_prefix_spans`, so the helper owns the visible prefix for every `/subagents` picker row.
- Not safe to delete: `codex-rs/tui/src/multi_agents.rs:75` centralizes the status glyph, with a direct branch between closed and non-closed entries.
- Not safe to delete: `codex-rs/tui/src/bottom_pane/selection_popup_common.rs` and `codex-rs/tui/src/bottom_pane/list_selection_view.rs` render `name_prefix_spans` as part of the selection row rather than dropping it, so removing the dot changes user-visible TUI behavior.
- Not safe to delete: `git log -p --follow -S 'agent_picker_status_dot_spans' -- codex-rs/tui/src/multi_agents.rs` shows the helper was introduced by `829d1080f641197c3ce8351c3e9951dccc3636c6` ("feat: keep dead agents in the agent picker"), which ties the dot to the explicit feature of keeping closed agents visible.
- `git grep -n "agent_picker_status_dot_spans"` found one rendering call path and the module import, which makes this helper small, local, and right-sized rather than an over-built abstraction.
- `codex-rs/tui/styles.md:10` states that user input tips, selection, and status indicators use ANSI `cyan`; this supports a small style correction over deletion or a new style exception.

## Risks
- If another rendered field already communicates closed/open state in the picker with equal compactness, deleting the dot could be less harmful; I found no such field in the traced `SelectionItem` construction.
- If maintainers decide that the marker should distinguish actively running agents from merely open agents, the current boolean `is_closed` helper may become too coarse; that would be a state-model expansion, not a deletion.
- ANSI cyan may still vary by terminal theme, but it follows the existing repo style guide and avoids creating a second status color rule for one Ghostty report.

## Escalation triggers (if any)
- none

## Reasoning trace (internal — for meta-judge)
- Reference-frame note: terminal UI accessibility should preserve non-text state affordances when they carry navigation meaning, and repo-local semantic color tokens should be followed unless a bounded exception is justified.
- Why I claim this can be deleted: I do not claim deletion is safe; the feature is load-bearing for the `/subagents` picker state cue.
- What I checked to verify safety: direct symbol search, the only caller in `open_agent_picker`, row-prefix rendering through `SelectionItem.name_prefix_spans`, the TUI style guide, and the historical commit that introduced the helper for visible closed-agent picker entries.
- What I cannot decide alone: the exact implementation contract belongs to the consensus controller, but the delete-role evidence favors keeping the marker and using the existing cyan status-indicator rule rather than deleting the dot or adding a green bold/larger exception.

🤖 Structural solver picks cyan bold open dot for /subagents

TL;DR

• What this is: Round 2 structural design input for issue /subagents active status dot is nearly indistinguishable in Ghostty default dark theme #27's /subagents status-dot contrast bug.
• Current state or conclusion: The clean contract is the same bullet glyph, cyan plus bold for open/non-closed threads, and default foreground plus dim for closed threads.
• What the controller does next: Compare this with the other round 2 solver outputs and, if consensus holds, dispatch the small codex-tui implementation with focused span-style coverage.

Structural recommendation

The verified rendering path is TUI-local. in passes into , so that helper owns the visible prefix for each Subagents picker row. in currently uses green for the non-closed marker, while says user input tips, selection, and status indicators use ANSI cyan.

Recommended contract:

State	Glyph	Foreground	Weight	Why
Open/non-closed		ANSI cyan	bold	Treats the marker as a status indicator and adds a non-color contrast cue.
Closed		default	dim	Keeps the row width stable while matching the closed-thread low-emphasis contract.

No new abstraction is needed for this bug. The existing helper is already the single presentation boundary, and adding a private enum would only be justified if maintainers want a broader state model later. The focused regression should live in and assert the dot content plus , , default foreground, and styling. tests should not be used here because they do not exercise the picker rendering path.

## Recommended framing
The `/subagents` picker status dot should be treated as a TUI status indicator, not as a success marker. The verified path is `codex-rs/tui/src/app/session_lifecycle.rs`, where `open_agent_picker` passes `agent_picker_status_dot_spans(entry.is_closed)` into `SelectionItem.name_prefix_spans`, and `codex-rs/tui/src/multi_agents.rs` currently renders non-closed dots as ANSI green. The structural fix is to keep the compact dot affordance, render the open/non-closed dot as the same `•` glyph with ANSI cyan plus bold weight, and render the closed dot as the same `•` glyph with default foreground plus dim weight. This follows `codex-rs/tui/styles.md` by construction, improves Ghostty dark-theme contrast without custom colors, and keeps shape stable so row widths and picker behavior do not change.

Reference-frame note: terminal UI semantic color-token discipline plus accessibility-by-multiple-cues. A status indicator should use the repo's status color token, and it should not rely on color alone when the state distinction is important.

## Concrete plan
- New abstractions (if any): none. The existing private helper `agent_picker_status_dot_spans(is_closed: bool) -> Vec<Span<'static>>` is already the presentation boundary and has one direct caller, so a new enum would add review surface without a second concrete caller. If maintainers want to remove the boolean later, a private `AgentPickerStatusDot::{Open, Closed}` enum is the only reasonable local shape, but it is not required for this bug.
- Files:
  - `codex-rs/tui/src/multi_agents.rs`: change the open/non-closed marker from `"•".green()` to `"•".cyan().bold()`, change the closed marker from plain `"•"` to `"•".dim()`, and add a focused regression test in the existing inline `tests` module.
  - `codex-rs/tui/src/app/session_lifecycle.rs`: no behavior change required; it remains the single callsite that connects `AgentPickerThreadEntry::is_closed` to the picker row prefix.
- LOC delta: ~+24 / -2.
- Tests to add:
  - One `codex-tui` unit test in `codex-rs/tui/src/multi_agents.rs` asserting the open dot content is `•`, foreground is `Color::Cyan`, `Modifier::BOLD` is present, and `Modifier::DIM` is absent.
  - The same test should assert the closed dot content is `•`, foreground is `None`, `Modifier::DIM` is present, and `Modifier::BOLD` is absent.
  - No `codex-apply-patch` test should be added for this issue because the verified rendering path is in `codex-tui`, and apply-patch coverage would not exercise the picker.
  - Run `just fmt` from `codex-rs`, then `just test -p codex-tui`. If an existing rendered snapshot changes, inspect the generated `*.snap.new` and accept only the intended `codex-tui` snapshot update.
- Schema/protocol changes (if any): none. No app-server, protocol, CLI, config, or session-resume wire shape changes.
- Governance/ruleset changes (if any): none. The existing style guide already contains the required rule.
- Runtime cost: no latency change; no additional async hops; one extra style modifier on the open span and one on the closed span; allocation count remains one `Vec<Span>` with two spans per picker row.
- 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: not applicable.
- Do not author helper-owned decomposition tracking comments or child fingerprint lines; the checked-in #403 helper is the only writer for the parent tracking grammar and per-child idempotency fingerprints: not applicable.

## Risks
- Cyan plus bold is slightly more visually assertive than a pure color-token fix, but the added weight is bounded to a one-character status prefix and directly addresses the reported dark-theme indistinguishability.
- Leaving the glyph as `•` avoids row-width churn, but it means the improvement relies on semantic color and weight rather than a larger shape. That is the right trade-off here because the picker already has a compact prefix contract.
- The closed marker becomes dim instead of plain default foreground. This is consistent with `AgentPickerThreadEntry::is_closed` documenting that closed threads should render dimmed, but it should be covered by the helper test so the visual hierarchy is explicit.

## Escalation triggers (if any)
- none

## Reasoning trace (internal — for meta-judge)
- Why this structure beats a documented exception: The issue is caused by using the success/addition color for a status indicator. Changing the helper to use cyan means the implementation follows the existing TUI style rule instead of carving out a Ghostty-specific or subagent-specific exception.
- Why I picked this abstraction over alternatives: No new abstraction is required because `agent_picker_status_dot_spans` is already the local rendering boundary and has one caller. A private enum would be acceptable only if maintainers want a self-documenting signature, but it is not necessary to make the bug impossible at this boundary.
- What I cannot decide alone: Whether maintainers prefer a future broader state model that differentiates actively running agents from merely open agents. That is outside this contrast bug because the current callsite passes only `is_closed`.

🤖 Meta-judge requests round 3 for exact status-dot modifiers

TL;DR

• What this is: Round 2 meta-judge arbitration for issue /subagents active status dot is nearly indistinguishable in Ghostty default dark theme #27.
• Current state or conclusion: The solvers agree on the codex-tui helper, the • glyph, and ANSI cyan, but not on bold/open and dim/closed modifiers.
• What the controller does next: Run round 3 with the narrowed question about the exact modifier contract the regression test should enforce.

---

Arbitration result

The three required round-2 solver artifacts are present for issue 27 and match their roles. The delete solver abstains with evidence that agent_picker_status_dot_spans is the compact open/closed cue rendered in the /subagents picker, so deletion is compatible-neutral under the Path A manual-issue exception.

The two implementation-bearing solvers made real progress from round 1: both now choose the TUI path, codex-rs/tui/src/multi_agents.rs, the same • glyph, ANSI cyan for open/non-closed rows, no new abstraction, and focused codex-tui span-style coverage. The remaining disagreement is still user-visible and testable: minimal wants plain cyan for open and plain default for closed, while structural wants cyan plus Modifier::BOLD for open and default plus Modifier::DIM for closed.

Option	Current support	Trade-off
Plain •.cyan() open, plain default • closed	Minimal	Smallest visual change and preserves exact current modifiers, but may rely on color alone.
•.cyan().bold() open, default •.dim() closed	Structural	Adds non-color emphasis and de-emphasis, but changes two style modifiers.
Delete the marker	Delete solver rejects	Removes the state cue and is not implementation-bearing consensus.

Round 3 should only answer the exact style contract: whether Modifier::BOLD must be present or absent on the open cyan dot, and whether Modifier::DIM must be present or absent on the closed default dot. No source implementation is authorized yet because the regression tests would encode different expected spans.

## Decision
Decision: converge for one more narrowed round. Reference-frame note: this is a terminal UI semantic-color and accessibility affordance decision; the accepted plan should preserve the compact open/closed state cue, use the repo's status-indicator color token, and make the exact rendered span contract testable. The Path A compatible-neutral exception applies to the delete solver because this is a manual issue-driven work unit and the delete artifact shows the dot is load-bearing rather than deletable. The two implementation-bearing solvers now agree on the bounded `codex-tui` path, the `codex-rs/tui/src/multi_agents.rs` helper, the same `•` glyph, ANSI cyan for open/non-closed entries, no new abstraction, and focused span-style regression coverage. They still contradict each other on the exact style modifiers: minimal requires no unexpected bold/dim modifiers and keeps closed default, while structural requires `Modifier::BOLD` on the open cyan dot and `Modifier::DIM` on the closed default dot. Because the tests would enforce different visual contracts, implementation dispatch is not authorized yet.

  - State the exact open/non-closed marker glyph, foreground color, and modifiers, including whether `Modifier::BOLD` must be present or absent.
  - State the exact closed marker glyph, foreground color, and modifiers, including whether `Modifier::DIM` must be present or absent.
  - State whether modifier changes are required for Ghostty default dark-theme readability, or whether the repo-local ANSI cyan status token is sufficient.
  - State the focused `codex-tui` regression assertions that should be implemented in `codex-rs/tui/src/multi_agents.rs`.
- Round number this fires: 3; marker payload uses source round `2`
- Progress since prior round: both implementation solvers moved from green-vs-cyan disagreement to agreement on ANSI cyan, the same `•` glyph, no new abstraction, the `codex-rs/tui/src/multi_agents.rs` helper, and `codex-tui` span-style coverage; only modifier presence remains unresolved.

🤖 Minimal solver keeps the cyan dot plain

TL;DR

• What this is: Round 3 minimal-change solver output for issue /subagents active status dot is nearly indistinguishable in Ghostty default dark theme #27.
• Current state or conclusion: Use the existing • glyph with ANSI cyan for open/non-closed entries, and keep closed entries on the default foreground with no dim modifier.
• What the controller does next: Compare this with the other round 3 solver outputs and, if consensus holds, dispatch the bounded codex-tui implementation plus focused span-style regression coverage.

Minimal modifier contract

The verified rendering path is codex-rs/tui/src/multi_agents.rs, where agent_picker_status_dot_spans builds the row prefix for the Subagents picker. open_agent_picker in codex-rs/tui/src/app/session_lifecycle.rs passes that prefix into SelectionItem.name_prefix_spans, which is the selection-row field that carries the visible prefix.

The smallest fix is to change the open/non-closed marker from green to ANSI cyan because codex-rs/tui/styles.md assigns cyan to status indicators and green to success/addition states. The style guide does not require a weight modifier for status dots, so the minimal contract should avoid adding new Modifier::BOLD or Modifier::DIM expectations in this round.

State	Glyph	Foreground	Modifier contract	Trade-off
Open/non-closed	•	ANSI cyan	no bold required	One-token semantic color fix; preserves row width and current visual weight.
Closed	•	default	no dim required	Keeps existing closed rendering; avoids making closed rows harder to read.

Recommended implementation scope: touch codex-rs/tui/src/multi_agents.rs, replace .green() with .cyan(), and add one focused helper test asserting the returned spans, including the absence of bold and dim modifiers. codex-apply-patch tests should not be used here because they do not render the Subagents picker path.

最小可行边界仍然是只改 `codex-rs/tui/src/multi_agents.rs` 里 `agent_picker_status_dot_spans` 的 open/non-closed 分支：把当前 `"•".green()` 改成同 glyph 的 `"•".cyan()`，并保持 closed 分支为默认前景的 `"•".into()`，不加 `Modifier::BOLD` 或 `Modifier::DIM`。我已验证 `codex-rs/tui/src/app/session_lifecycle.rs` 通过 `SelectionItem.name_prefix_spans` 直接渲染这个 helper 的返回值，且 `codex-rs/tui/styles.md` 明确说 status indicators 使用 ANSI `cyan`、green 用于 success/additions；样式规则没有要求状态点加粗，也没有要求关闭项用 dim。reference-frame note: terminal UI semantic color-token discipline plus minimum-diff accessibility fix; first align the status indicator with the shared semantic token, then only add weight/de-emphasis if evidence shows the token-level fix is insufficient.

## Concrete plan
- Files:
  - `codex-rs/tui/src/multi_agents.rs`: change the non-closed dot from `"•".green()` to `"•".cyan()`. Keep the closed dot as `"•".into()` and keep the trailing space unchanged.
  - `codex-rs/tui/src/multi_agents.rs`: add one focused regression test in the existing `#[cfg(test)] mod tests` that asserts the full `Vec<Span<'static>>` for open and closed dots: open content `•`, foreground `Some(Color::Cyan)`, no `Modifier::BOLD`; closed content `•`, foreground `None`, no `Modifier::DIM`; both include the unchanged trailing space.
  - `codex-rs/tui` snapshot coverage: if an existing picker/render snapshot exposes `name_prefix_spans` styling, update it; otherwise keep the style regression at the helper boundary because plain text snapshots generally cannot encode ratatui span modifiers reliably.
- LOC delta: ~+18 / -1.
- Tests to add/modify:
  - Add one `codex-tui` helper test in `codex-rs/tui/src/multi_agents.rs`.
  - Run `just fmt`, then `just test -p codex-tui`.
  - If a snapshot changes or a new snapshot is added for the picker rendering path, inspect pending snapshots and accept only the intended `codex-tui` update.
- Governance/ruleset change (if any): none.
- Migration path: no migration needed.

## Risks
- Plain cyan is a semantic and likely contrast improvement, but it still relies on color as the only open/closed distinction; if Ghostty default dark contrast remains inadequate after implementation verification, the next smallest follow-up would be adding `Modifier::BOLD` to the open cyan dot only.
- Adding `Modifier::DIM` to the closed dot is not required to fix the reported active-dot visibility bug and could make closed entries harder to read in terminals with already-muted defaults.
- The issue body mentions `codex-apply-patch` tests, but the verified owned path is `codex-tui`; apply-patch coverage would not exercise this picker prefix.

## Escalation triggers (if any)
- none

## Reasoning trace (internal — short, for meta-judge)
- Why this is the minimum: the violation is localized to one helper with one verified picker caller; one style-token edit changes the user-visible dot without changing glyph width, selection behavior, sorting, liveness state, or app-server/API surfaces.
- What I considered but rejected: cyan plus bold for open and dim for closed because that changes two modifiers beyond the explicit style-guide violation; a new enum because the helper has one direct boolean caller and no broader state-model change is needed; `codex-apply-patch` tests because they do not render the `/subagents` picker.
- What I cannot decide alone: whether maintainers want a future broader state contract that distinguishes actively running from merely open agents; this issue can be resolved without that expansion.

🤖 Structural solver selects bold cyan open dot and dim closed dot

TL;DR

• What this is: Round 3 structural design input for issue /subagents active status dot is nearly indistinguishable in Ghostty default dark theme #27's /subagents status-dot contrast bug.
• Current state or conclusion: Use the same • glyph, with ANSI cyan plus bold for open/non-closed rows and default foreground plus dim for closed rows.
• What the controller does next: Compare this with the other round 3 solver outputs and, if consensus holds, dispatch the bounded codex-tui implementation plus focused span-style coverage.

Structural recommendation

The verified rendering path is TUI-local. open_agent_picker in codex-rs/tui/src/app/session_lifecycle.rs passes agent_picker_status_dot_spans(entry.is_closed) into SelectionItem.name_prefix_spans; this means the helper owns the visible row prefix in the Subagents picker. agent_picker_status_dot_spans in codex-rs/tui/src/multi_agents.rs currently uses green for open/non-closed dots, while codex-rs/tui/styles.md assigns ANSI cyan to status indicators.

Recommended exact modifier contract:

State	Glyph	Foreground	Modifier	Trade-off
Open/non-closed	•	ANSI cyan	Modifier::BOLD present	Uses the repo status color and adds a non-color visibility cue for the dark-theme report.
Closed	•	default	Modifier::DIM present	Keeps the same row width while making closed entries lower emphasis.

No new abstraction is needed for this bug. agent_picker_status_dot_spans is already the single presentation boundary, and a private enum would only be justified if a later change adds a broader open/running/closed state model. The focused regression should live in codex-rs/tui/src/multi_agents.rs and assert both the two-span content and the exact Color::Cyan, Modifier::BOLD, default foreground, and Modifier::DIM styling. codex-apply-patch tests should not be used here because they do not exercise the picker rendering path.

## Recommended framing
The exact `/subagents` status-dot contract should be `•`.cyan().bold() for open/non-closed rows and `•`.dim() for closed rows. The verified rendering path is local to `codex-tui`: `open_agent_picker` in `codex-rs/tui/src/app/session_lifecycle.rs` passes `agent_picker_status_dot_spans(entry.is_closed)` into `SelectionItem.name_prefix_spans`, and `agent_picker_status_dot_spans` in `codex-rs/tui/src/multi_agents.rs` currently renders open/non-closed dots as green. Cyan follows the existing status-indicator rule; `Modifier::BOLD` on the open dot and `Modifier::DIM` on the closed dot give the state cue a non-color emphasis/de-emphasis channel without changing glyph width, row search text, picker ordering, app-server contracts, or terminal-specific palette logic. Reference-frame note: terminal UI semantic color-token discipline plus accessibility-by-multiple-cues; important status state should not depend on hue alone when the reported failure is low visibility in a dark terminal theme.

## Concrete plan
- New abstractions (if any): none. The existing `agent_picker_status_dot_spans(is_closed: bool) -> Vec<Span<'static>>` helper is the single TUI presentation boundary for this marker and has one direct caller. A private enum such as `AgentPickerStatusDot::{Open, Closed}` would be reasonable only if a broader picker state model is introduced later; it is not justified for this two-state rendering fix.
- Files:
  - `codex-rs/tui/src/multi_agents.rs`: change the open/non-closed marker from `"•".green()` to `"•".cyan().bold()`, change the closed marker from plain `"•"` to `"•".dim()`, keep the trailing `" "` span unchanged, and add a focused test in the existing inline `tests` module.
  - `codex-rs/tui/src/app/session_lifecycle.rs`: no behavior change. This file remains evidence for the single callsite connecting `AgentPickerThreadEntry::is_closed` to the visible picker row prefix.
- LOC delta: ~+24 / -2.
- Tests to add:
  - Add one `codex-tui` regression test in `codex-rs/tui/src/multi_agents.rs` that compares the returned `Vec<Span<'static>>` or otherwise asserts the complete two-span contract for both states.
  - The open/non-closed case must assert glyph `•`, trailing space unchanged, foreground `Some(Color::Cyan)`, `Modifier::BOLD` present, and `Modifier::DIM` absent.
  - The closed case must assert glyph `•`, trailing space unchanged, foreground `None`, `Modifier::DIM` present, and `Modifier::BOLD` absent.
  - Do not add `codex-apply-patch` tests for this issue; that crate does not exercise the verified `/subagents` picker rendering path.
  - Run `just fmt` from `codex-rs`, then `just test -p codex-tui`. If a rendered snapshot changes, inspect the generated `*.snap.new` and accept only the intended `codex-tui` snapshot update.
- Schema/protocol changes (if any): none. No app-server, protocol, CLI, config, persistence, or resume compatibility surface changes.
- Governance/ruleset changes (if any): none. The existing `codex-rs/tui/styles.md` rule already assigns status indicators to ANSI cyan and secondary text to dim.
- Runtime cost: no latency change; no additional async hops; no extra persistent state; allocation count remains one `Vec<Span>` with two spans per picker row. The only runtime difference is two style modifier bits on existing spans.
- 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: not applicable.
- Do not author helper-owned decomposition tracking comments or child fingerprint lines; the checked-in #403 helper is the only writer for the parent tracking grammar and per-child idempotency fingerprints: not applicable.

## Risks
- This is a stronger visual change than plain cyan because it adds `Modifier::BOLD` and `Modifier::DIM`; the trade-off is justified because the issue reports near-indistinguishability, and the modifiers are limited to a one-character prefix.
- `DIM` on the closed dot could be too subtle in some themes, but closed entries are intentionally lower emphasis and the open dot remains the primary affordance to make active/open rows discoverable.
- Keeping the same `•` glyph avoids layout churn, but it means the contrast improvement comes from semantic color plus weight rather than a larger shape. That keeps the fix bounded to style, not row geometry.

## Escalation triggers (if any)
- none

## Reasoning trace (internal — for meta-judge)
- Why this structure beats a documented exception: A documented green exception would preserve the mismatch between a status indicator and the style guide's cyan token. Cyan plus explicit modifiers aligns the helper with the existing rule and removes the need for terminal-specific Ghostty handling.
- Why I picked this abstraction over alternatives: No new abstraction is needed because the helper already isolates the rendering contract and there is only one concrete caller. Adding an enum would improve the boolean callsite only slightly while increasing review surface for a one-helper visual fix.
- What I cannot decide alone: Whether the product should later distinguish actively running agents from merely open agents with a third marker. That requires a broader state model than this issue, whose verified input is only `is_closed`.
