-- Rust workspace lives under `crates/`: `miyabi-cli` (CLI entry), `miyabi-tui` (UI), and `miyabi-core` (shared logic, config, sessions, Polaris/DTP: `gate`, `store`, `lock`, `protocol`). Shared workspace config in `Cargo.toml`.
+- Rust workspace lives under `crates/`: `mergegate-cli` (CLI entry), `mergegate-tui` (UI), and `mergegate-core` (shared logic, config, sessions, MergeGate/DTP: `gate`, `store`, `lock`, `protocol`). Shared workspace config in `Cargo.toml`.
 - ルートに `package.json` はない（過去テンプレート由来の記述は削除済み）。フロント系ツールが別ディレクトリにあれば、その README に従う。
 - Supporting assets: `.claude/` agent configs, `docs/` for design notes, `project_memory/` for Polaris タスク台帳（`tasks.json`）、`.github/` for CI workflows。

-# Miyabi CLI
+# MergeGate
 
-A powerful terminal-based AI assistant with TUI (Terminal User Interface) built in Rust.
+MergeGate is a deterministic execution protocol for AI-assisted development.
+It is the execution layer for GitNexus-style code intelligence: GitNexus helps agents understand what will break, and MergeGate makes them execute that work in a safe, verifiable order.
+
+In short:
+
+- `GitNexus`: understand the codebase
+- `MergeGate`: execute changes safely
+
+The project currently supports both `miyabi` and `mergegate` as CLI entrypoints. `miyabi` remains the legacy/default command, and `mergegate` is the product-aligned alias.
+
+This repository has two common entry points:
+
+- `miyabi tui` / `mergegate tui`: interactive terminal assistant
+- `miyabi gate` / `mergegate gate`: deterministic task execution and file-lock workflow for repo work
+
+If you arrived here because of deterministic execution, task locks, PR gates, or agent-safe repo work, start with `mergegate gate` or `miyabi gate`, not the TUI.
 
 ## 60-Second Setup
 
 ```bash
 # 1. Clone and build
-git clone https://github.com/ShunsukeHayashi/miyabi-cli-standalone.git
-cd miyabi-cli-standalone
+git clone https://github.com/ShunsukeHayashi/mergegate.git
+cd mergegate
 cargo build --release
 
 # 2. Set API key
 export ANTHROPIC_API_KEY="sk-ant-..."
 
 # 3. Run
-./target/release/miyabi tui
+./target/release/mergegate tui
 ```
 
-That's it! Start chatting with Claude in your terminal.
+That's it. Start with the TUI, or jump straight into `mergegate gate` for repo workflow control.

-## Features
+## Why MergeGate
 
-- **Interactive TUI** - Beautiful terminal interface with markdown rendering
-- **Chat Mode** - Conversational AI assistant
-- **Agent Mode** - Autonomous task execution with tool approval
-- **Session Management** - Persist and resume conversations
+- **Execution layer for code intelligence** - Pair blast-radius understanding with deterministic execution, not chat-only automation
+- **Deterministic task execution** - Register, analyze, lock, review, and merge in a verifiable order
+- **Repo-safe agent workflow** - File locks and gate checks reduce accidental overlap and unsafe edits
+- **Interactive TUI** - Terminal assistant for chat, prompts, and agent execution
+- **Agent mode** - Autonomous execution with tool approval
+- **Session management** - Persist and resume conversations
 - **Configurable** - TOML-based configuration
-- **Extended Thinking** - Support for Claude 4.5+ extended thinking
+
+## Positioning
+
+MergeGate was designed for teams that already believe code understanding is not enough.
+Knowing the blast radius of a change is only half of the problem. Agents also need a protocol for when work starts, which files are locked, what must be recorded before editing, and what counts as done.
+
+That is the role split:
+
+- `GitNexus`: query, context, impact, detect-changes, rename, wiki, graph exploration
+- `MergeGate`: register, impact record, assign, file lock, branch, PR, merge, completion discipline
+
+If GitNexus answers "what is this change connected to?", MergeGate answers "how do we carry it through safely?"

+### B. Use MergeGate as a task execution gate
+
+If you are working inside a repository and want task registration, impact tracking, file locks, and PR/merge recording, use `mergegate gate` or `miyabi gate`.
+
+#### 1. Check whether the repo is already initialized
+
+```bash
+./target/release/miyabi gate status
+```
+
+If you see `tasks: 0`, that means the ledger exists but is currently empty.
+
+#### 2. Initialize MergeGate for this repo if needed
+
+```bash
+./target/release/miyabi gate init
+```
+
+This creates `project_memory/tasks.json` and prepares the repo for gate-managed work.
+
+#### 3. Read the built-in workflow guide
+
+```bash
+./target/release/miyabi gate guide
+```
+
+#### 4. Start a task
+
+```bash
+./target/release/miyabi gate register --issue 123 --title "Fix login redirect"
+./target/release/miyabi gate impact issue-123 --risk medium --symbols 3
+./target/release/miyabi gate assign issue-123 --agent codex --node macbook --files "src/auth.rs"
+```
+
+Typical flow:
+
+1. `register`
+2. `impact`
+3. `assign`
+4. implement
+5. `branch`
+6. `pr`
+7. `merge` or `manual-complete`

 ## Usage

 ## はじめに
 
-Miyabi CLIは、ターミナルで動作するAIアシスタントです。Claude APIを使用して、対話型のチャットや自律的なタスク実行が可能です。
+MergeGate は、AI-assisted development 向けの deterministic task execution and merge workflow です。CLI では `miyabi` と `mergegate` の両方を使え、対話型の TUI と `gate` ベースの repo workflow を提供します。
+
+設計思想はシンプルです。
+
+- `GitNexus`: コードベースを理解する
+- `MergeGate`: 変更を安全に実行する
+
+影響範囲が分かるだけでは、AI エージェントは安全に開発できません。どの task を登録し、どのファイルを lock し、どの順序で branch / PR / merge まで進めるかを protocol として固定するのが MergeGate の役割です。

+# MergeGate CLI — Deterministic Execution Skill
+
+## この repo での正しい入口
+
+- 開発中: `cargo run -p mergegate-cli --bin mergegate -- gate ...`
+- ビルド済み: `./target/release/mergegate gate ...`
+
+## 概要
+
+MergeGate (DTP) の公式 GATE CLI。タスクの登録・ロック・検証・完了を確定的に実行する。
+ファイル編集前に必ず `mergegate gate assign` または `miyabi gate assign` でロックを取得すること。
+
+この `mergegate` リポジトリでは `mergegate gate` と `miyabi gate` の両方が使える。
+他環境に `miyabi-gate` という別ラッパーがあっても、この repo では `mergegate gate` を先に案内する。
+
+## 初回ユーザー向けの最短導線
+
+まずは次の 3 つだけ覚えればよい。
+
+```bash
+./target/release/mergegate gate status
+./target/release/mergegate gate init
+./target/release/mergegate gate guide
+```
+
+意味:
+
+- `status`: すでに初期化済みか確認する
+- `init`: 未導入なら `project_memory/tasks.json` を作る
+- `guide`: 正しい手順をその場で読む
+
+`tasks: 0` は異常ではなく、「ledger はあるがタスクがまだない」状態。
+
+## クイックスタート
+
+```bash
+./target/release/mergegate gate init                                    # 初回のみ
+./target/release/mergegate gate register --issue 1 --title "タスク名"  # タスク登録
+./target/release/mergegate gate impact issue-1 --risk low --symbols 0  # 影響分析
+./target/release/mergegate gate assign issue-1 --agent claude --node macbook --files "src/main.rs"  # ロック獲得
+# → 作業実施
+./target/release/mergegate gate manual-complete issue-1 --reason "完了" --operator claude  # 完了
+```
+
+## トリガー
+
+MergeGate, mergegate gate, miyabi gate, miyabi-gate, polaris, dtp, タスク登録, ロック, assign, GATE, 確定的, deterministic, ファイルロック, 依存関係, DAG
+
+## 前提
+
+- バイナリ: `cargo build --release` で `target/release/mergegate` と `target/release/miyabi` を生成
+- tasks.json: `project_memory/tasks.json`（デフォルト）
+- repo 内の説明は `mergegate gate` を主表記として読む
+
+## 公式の使い分け
+
+- `mergegate-cli`: task の register、impact、assign、branch、pr、merge を進める
+- `mergegate-ops`: Phase 実行、品質チェック、handoff を進める
+- `polaris-gate` rule: `mergegate` での必須順序を強制する
+
+## コマンド一覧
+
+### タスク登録
+
+```bash
+./target/release/mergegate gate register --issue 45 --title "認証移行"

+./target/release/mergegate gate status task-001     # 特定タスク
+./target/release/mergegate gate --format json status
+```
+
+### 実行可能タスク

+```
+
+### Web ダッシュボード
+
+```bash

+```
+
+### escape hatch
+
+```bash
+./target/release/mergegate gate force-unlock task-001 --reason "agent crashed" --operator hayashi
+./target/release/mergegate gate manual-complete task-001 --reason "doc task, no PR" --operator hayashi
+```
+
+## exit code
+
+| コード | 意味 | エージェントの対処 |
+|--------|------|------------------|
+| 0 | 成功 | 次のステップへ進む |
+| 1 | GATE 拒否 | 理由を確認して条件を満たしてからリトライ |
+| 2 | 入力エラー | コマンドを修正して再実行 |
+
+## エージェントの使い方
+
+### Claude Code から
+
+```bash
+# タスク登録
+./target/release/mergegate gate --format json register --issue 45 --title "認証移行"
+
+# 状態確認
+./target/release/mergegate gate --format json status task-001
+
+# ロック獲得
+./target/release/mergegate gate assign task-001 --agent claude --node macbook --files "src/auth.rs"
+```
+
+### Codex から
+
+```bash
+# Codex は --format json で結果をパースする
+result=$(./target/release/mergegate gate --format json register --issue 45 --title "test")
+exit_code=$?
+if [ $exit_code -eq 0 ]; then
+  task_id=$(echo "$result" | jq -r '.task_id')
+  ./target/release/mergegate gate assign "$task_id" --agent codex --node macbook --files "src/test.rs"
+fi
+```
+
+### OpenClaw から
+
+```bash
+# OpenClaw main がディスパッチ
+./target/release/mergegate gate dispatchable
+# → サブエージェントに渡す
+```
+
+## Claude Code での正式運用
+
+1. `mergegate gate register` で task を作る
+2. `mergegate gate impact` で risk を記録する
+3. `mergegate gate assign` でロックを取ってから編集する
+4. 実装後に `mergegate gate branch` と `mergegate gate pr` を記録する
+5. merge 済みなら `mergegate gate merge`、PR を伴わない文書作業なら `manual-complete` を使う
+
+`mergegate` では `polaris-gate` rule が前提なので、assign 前の編集は不可。
+
+## GATE フロー
+
+```
+register (GATE 0: Issue必須)
+  → status: pending
+  → check_dependencies (GATE 2: 依存解決)
+  → status: ready
+  → impact (GATE 3: 分析記録 + HIGH承認)
+  → status: analyzing
+  → assign (GATE 4: ロック獲得)
+  → status: implementing
+  → branch (GATE 5: ブランチ名検証)
+  → pr (GATE 6: PR番号記録)
+  → status: reviewing
+  → merge (GATE 7: SHA検証)
+  → status: done ✅

+# MergeGate Ops — DTP Development Operations
+
+## 概要
+
+Deterministic Task Protocol (MergeGate) の開発・テスト・デプロイを自動化するスキル。
+Phase 実行、品質チェック、引き継ぎ、進捗アナウンスを一括管理。
+
+Claude Code では、このスキルは GATE 操作そのものを持たない。GATE 操作は `mergegate-cli` を使い、
+このスキルはその上で Phase と品質を管理する。
+
+## トリガー
+
+Polaris, polaris, dtp, 確定的, deterministic, phase, gate, autorun
+
+## 公式の役割分担
+
+- `mergegate-cli`: task register、impact、assign、branch、pr、merge
+- `mergegate-ops`: phase 実行、品質チェック、handoff、announce
+- `polaris-gate` rule: `miyabi-cli-standalone` での順序強制
+
+## Quick Start
+
+```bash
+cd /Users/shunsukehayashi/dev/platform/mergegate
+
+# 先に GATE を進める
+mergegate gate --format json status
+mergegate gate dispatchable
+
+# その後に MergeGate の品質チェックを回す
+cargo build
+cargo test
+cargo clippy --all-targets --all-features -- -D warnings
+```
+
+## コマンド
+
+### 品質チェック（毎回実行）
+
+```bash
+# 3点セット: これが全 GREEN = 品質 OK
+cargo build && cargo test && cargo clippy --all-targets --all-features -- -D warnings
+```
+
+### Phase 実行
+
+```bash
+# Phase N の TASKS.md を読んでチェックボックスを埋める
+cat autorun/phase-{N}-*/TASKS.md
+
+# GATE 確認
+cat autorun/phase-{N}-*/GATE.md
+
+# task 台帳の状態も確認
+mergegate gate --format json status
+mergegate gate --format json locks
+
+# Phase 完了時にタグを打つ
+git tag v0.{N+1}-phase{N}-done
+git push origin v0.{N+1}-phase{N}-done
+```
+
+### 引き継ぎ
+
+```bash
+# HANDOFF_NOTE.md を作成（autorun/HANDOFF.md のテンプレートに従う）
+# git commit + push
+# 次のエージェントに通知
+~/bin/announce "MergeGate: Phase {N} 完了。Phase {N+1} に引き継ぎます。"
+```
+
+### 進捗アナウンス
+
+```bash
+# Phase 開始
+~/bin/announce "MergeGate: Phase {N} 開始。{Phase名}を実行します。"
+
+# GATE 通過
+~/bin/announce "MergeGate: Phase {N} GATE 通過。テスト全て成功。"
+
+# エラー
+~/bin/announce "MergeGate: Phase {N} エラー。{理由}。リトライ {M} 回目。"
+
+# 完了
+~/bin/announce "MergeGate: Phase {N} 完了。次は Phase {N+1} です。"
+```
+
+### ロールバック
+
+```bash
+# 安全地点に戻る
+git tag  # タグ一覧を確認
+git checkout v0.{N}-phase{N-1}-done
+git checkout -b rollback/phase-{N}-retry
+# 修正後
+git checkout main && git merge rollback/phase-{N}-retry
+```
+
+### コンテキストアタッチメント
+
+```bash
+# assign 後に自動アタッチされる情報:
+# - Issue 本文
+# - Impact 分析結果
+# - Obsidian Vault の関連ノート (OBSIDIAN_VAULT_PATH 設定時)
+# - ロック対象ファイルの先頭30行
+# - depth-1 impact ファイル（直接呼び出し元）の先頭30行
+
+# 手動でアタッチ内容を確認:
+mergegate gate attach <task-id>
+
+# JSON 出力でプロンプト注入用:
+mergegate gate attach <task-id>
+```
+
+### Dream (学び抽出)
+
+```bash
+# タスクイベントからパターンを抽出:
+mergegate gate dream
+mergegate gate dream --auto  # 自動実行（launchd 毎日 03:00）
+```
+
+### Codex ディスパッチ
+
+```bash
+# Phase N を Codex にアサイン（attach でコンテキスト自動注入）
+mergegate gate attach <task-id> > /tmp/ctx.json
+tmux send-keys -t %{pane} "codex 'Execute task. Context: $(cat /tmp/ctx.json | head -100)'" Enter
+```
+
+### Agent Skill Bus 記録
+
+```bash
+npx agent-skill-bus record-run \
+  --agent {agent} \
+  --skill mergegate-ops \
+  --task "Phase {N}: {summary}" \
+  --result {success|fail} \
+  --score {0.0-1.0}
+```
+
+## 判断基準
+
+| 状況 | アクション |
+|------|-----------|
+| cargo test GREEN + clippy GREEN | Phase 続行 |
+| GATE 未登録 / assign 未実施 | `mergegate-cli` に戻る |
+| cargo test FAIL | 修正してリトライ（最大3回） |
+| 3回連続 FAIL | エスカレーション（人間に報告） |
+| 人間が「止めろ」 | 即座に停止、commit + push |

-# MiyabiGate — 確定的タスク実行スキル
-
-## バイナリ
-
-**`~/bin/miyabi-gate`** （全ノードにインストール済み）
-
-## 概要
-
-Polaris (DTP) の公式 GATE CLI。タスクの登録・ロック・検証・完了を確定的に実行する。
-ファイル編集前に必ず `miyabi-gate gate assign` でロックを取得すること。
-
-Claude Code では、このスキルを `MiyabiGate` として扱う。
-`miyabi` は別の hub CLI なので、Polaris の GATE 操作には使わず、標準コマンドは `miyabi-gate gate ...` とする。
-`miyabi gate` と打つと別 CLI の help を見に行くので、誤って使わないこと。
-
-## クイックスタート
-
-```bash
-miyabi-gate gate init                                    # 初回のみ
-miyabi-gate gate register --issue 1 --title "タスク名"  # タスク登録
-miyabi-gate gate impact issue-1 --risk low --symbols 0  # 影響分析
-miyabi-gate gate assign issue-1 --agent claude --node macbook --files "src/main.rs"  # ロック獲得
-# → 作業実施
-miyabi-gate gate manual-complete issue-1 --reason "完了" --operator claude  # 完了
-```
-
-## トリガー
-
-MiyabiGate, miyabi gate, miyabi-gate, polaris, dtp, タスク登録, ロック, assign, GATE, 確定的, deterministic, ファイルロック, 依存関係, DAG
-
-## 前提
-
-- バイナリ: `cargo build --release` で `target/release/miyabi` を生成
-- ワークスペース: `/Users/shunsukehayashi/dev/platform/miyabi-cli-standalone`
-- tasks.json: `project_memory/tasks.json`（デフォルト）
-
-## 公式の使い分け
-
-- `MiyabiGate`: task の register、impact、assign、branch、pr、merge を進める
-- `Polaris`: Phase 実行、品質チェック、handoff を進める
-- `polaris-gate` rule: `miyabi-cli-standalone` での必須順序を強制する
-
-## コマンド一覧
-
-### タスク登録
-
-```bash
-miyabi-gate gate register --issue 45 --title "認証移行"
-miyabi-gate gate register --issue 45 --title "認証移行" --format json
-miyabi-gate gate register --issue 45 --title "認証移行" --store-path /path/to/tasks.json
-```
-
-### タスク状態確認
-
-```bash
-miyabi-gate gate status                    # 全タスク一覧
-miyabi-gate gate status task-001           # 特定タスク
-miyabi-gate gate status --format json      # JSON出力
-```
-
-### 実行可能タスク
-
-```bash
-miyabi-gate gate dispatchable              # DAG依存解決済みのタスク
-miyabi-gate gate dispatchable --format json
-```
-
-### DAG 可視化
-
-```bash
-miyabi-gate gate dag                       # DAGレベル表示
-```
-
-### impact 記録
-
-```bash
-miyabi-gate gate impact task-001 --risk LOW --symbols 3
-miyabi-gate gate impact task-001 --risk HIGH --symbols 12  # → 人間承認が必要
-miyabi-gate gate impact task-001 --risk HIGH --symbols 12 --approve  # 承認付き
-```
-
-### ロック獲得 + 実装開始
-
-```bash
-miyabi-gate gate assign task-001 --agent claude --node macbook --files "src/auth.rs,src/middleware.rs"
-```
-
-### ブランチ記録
-
-```bash
-miyabi-gate gate branch task-001 feature/issue-45-auth
-```
-
-### PR 記録
-
-```bash
-miyabi-gate gate pr task-001 78
-```
-
-### merge 検証 + 完了
-
-```bash
-miyabi-gate gate merge task-001 a1b2c3d4e5f6a1b2c3d4e5f6a1b2c3d4e5f6a1b2
-```
-
-### ロック一覧
-
-```bash
-miyabi-gate gate locks                     # 現在のロック一覧
-miyabi-gate gate locks --format json
-```
-
-### escape hatch
-
-```bash
-miyabi-gate gate force-unlock task-001 --reason "agent crashed" --operator hayashi
-miyabi-gate gate manual-complete task-001 --reason "doc task, no PR" --operator hayashi
-```
-
-## exit code
-
-| コード | 意味 | エージェントの対処 |
-|--------|------|------------------|
-| 0 | 成功 | 次のステップへ進む |
-| 1 | GATE 拒否 | 理由を確認して条件を満たしてからリトライ |
-| 2 | 入力エラー | コマンドを修正して再実行 |
-
-## エージェントの使い方
-
-### Claude Code から
-
-```bash
-# タスク登録
-miyabi-gate gate register --issue 45 --title "認証移行" --format json
-
-# 状態確認
-miyabi-gate gate status task-001 --format json
-
-# ロック獲得
-miyabi-gate gate assign task-001 --agent claude --node macbook --files "src/auth.rs"
-```
-
-### Codex から
-
-```bash
-# Codex は --format json で結果をパースする
-result=$(miyabi-gate gate register --issue 45 --title "test" --format json)
-exit_code=$?
-if [ $exit_code -eq 0 ]; then
-  task_id=$(echo "$result" | jq -r '.task_id')
-  miyabi-gate gate assign "$task_id" --agent codex --node macbook --files "src/test.rs"
-fi
-```
-
-### OpenClaw から
-
-```bash
-# OpenClaw main がディスパッチ
-miyabi-gate gate dispatchable --format json | jq -r '.[0].id'
-# → サブエージェントに渡す
-```
-
-## Claude Code での正式運用
-
-1. `miyabi-gate gate register` で task を作る
-2. `miyabi-gate gate impact` で risk を記録する
-3. `miyabi-gate gate assign` でロックを取ってから編集する
-4. 実装後に `miyabi-gate gate branch` と `miyabi-gate gate pr` を記録する
-5. merge 済みなら `miyabi-gate gate merge`、PR を伴わない文書作業なら `manual-complete` を使う
-
-`miyabi-cli-standalone` では `polaris-gate` rule が前提なので、assign 前の編集は不可。
-
-## GATE フロー
-
-```
-register (GATE 0: Issue必須)
-  → status: pending
-  → check_dependencies (GATE 2: 依存解決)
-  → status: ready
-  → impact (GATE 3: 分析記録 + HIGH承認)
-  → status: analyzing
-  → assign (GATE 4: ロック獲得)
-  → status: implementing
-  → branch (GATE 5: ブランチ名検証)
-  → pr (GATE 6: PR番号記録)
-  → status: reviewing
-  → merge (GATE 7: SHA検証)
-  → status: done ✅
-```

-# Polaris Ops — DTP 開発オペレーションスキル
-
-## 概要
-
-Deterministic Task Protocol (Polaris) の開発・テスト・デプロイを自動化するスキル。
-Phase 実行、品質チェック、引き継ぎ、進捗アナウンスを一括管理。
-
-## トリガー
-
-polaris, dtp, 確定的, deterministic, phase, gate, autorun
-
-## コマンド
-
-### 品質チェック（毎回実行）
-
-```bash
-# 3点セット: これが全 GREEN = 品質 OK
-cargo build && cargo test && cargo clippy --all-targets --all-features -- -D warnings
-```
-
-### Phase 実行
-
-```bash
-# Phase N の TASKS.md を読んでチェックボックスを埋める
-cat autorun/phase-{N}-*/TASKS.md
-
-# GATE 確認
-cat autorun/phase-{N}-*/GATE.md
-
-# Phase 完了時にタグを打つ
-git tag v0.{N+1}-phase{N}-done
-git push origin v0.{N+1}-phase{N}-done
-```
-
-### 引き継ぎ
-
-```bash
-# HANDOFF_NOTE.md を作成（autorun/HANDOFF.md のテンプレートに従う）
-# git commit + push
-# 次のエージェントに通知
-~/bin/announce "Polaris: Phase {N} 完了。Phase {N+1} に引き継ぎます。"
-```
-
-### 進捗アナウンス
-
-```bash
-# Phase 開始
-~/bin/announce "Polaris: Phase {N} 開始。{Phase名}を実行します。"
-
-# GATE 通過
-~/bin/announce "Polaris: Phase {N} GATE 通過。テスト全て成功。"
-
-# エラー
-~/bin/announce "Polaris: Phase {N} エラー。{理由}。リトライ {M} 回目。"
-
-# 完了
-~/bin/announce "Polaris: Phase {N} 完了。次は Phase {N+1} です。"
-```
-
-### ロールバック
-
-```bash
-# 安全地点に戻る
-git tag  # タグ一覧を確認
-git checkout v0.{N}-phase{N-1}-done
-git checkout -b rollback/phase-{N}-retry
-# 修正後
-git checkout main && git merge rollback/phase-{N}-retry
-```
-
-### Codex ディスパッチ
-
-```bash
-# Phase N を Codex にアサイン
-tmux send-keys -t %{pane} "codex 'Execute Phase {N}. Read autorun/phase-{N}-*/TASKS.md. Run cargo test when done. Write HANDOFF_NOTE.md.'" Enter
-```
-
-### Agent Skill Bus 記録
-
-```bash
-npx agent-skill-bus record-run \
-  --agent {agent} \
-  --skill polaris-ops \
-  --task "Phase {N}: {summary}" \
-  --result {success|fail} \
-  --score {0.0-1.0}
-```
-
-## 判断基準
-
-| 状況 | アクション |
-|------|-----------|
-| cargo test GREEN + clippy GREEN | Phase 続行 |
-| cargo test FAIL | 修正してリトライ（最大3回） |
-| 3回連続 FAIL | エスカレーション（人間に報告） |
-| 人間が「止めろ」 | 即座に停止、commit + push |
