- 当执行完变更需要验证是否应保留、候选被标记 pending 需要人工审批、或想查看待审队列时使用。7 层机械门禁: Schema→Compile→Lint→Regression→Review→Doubt→HumanReview，任一 required 层失败即拒绝。不用于打分（用 improvement-discriminator）或执行变更（用 improvement-executor）。

Improvement Gate
7-layer mechanical quality gate: any required layer fail = reject/revert.
When to Use
- 验证已执行的候选是否应保留（gate.py）
- 管理人工审核队列（review.py --list）
- 完成待审批项（review.py --complete）
When NOT to Use
- 给候选打分 → use
improvement-discriminator - 执行文件变更 → use
improvement-executor - 评估 skill 结构 → use
improvement-learner
7-Layer Gate
| Layer | Gate | Required | Pass Condition |
|---|---|---|---|
| 0 | SchemaGate | Yes | Candidate has id, category, risk_level, execution_plan |
| 1 | CompileGate | Yes | Modified .py files pass py_compile; non-Python files auto-pass |
| 2 | LintGate | No (advisory) | No lines >120 chars, no mixed tabs/spaces in diff |
| 3 | RegressionGate | Yes | Evaluator verdict != "reject" (checks evaluator_evidence) |
| 4 | ReviewGate | Yes | Discriminator recommendation=accept AND panel not DISPUTED AND LLM judge != reject |
| 5 | DoubtGate | Yes | Candidate text has < threshold hedging words (threshold varies by category: docs=2, prompt=4, code=3) |
| 6 | HumanReviewGate | No (advisory) | Flags needs_human=true for medium/high risk or prompt/workflow/tests/code categories |
Gate execution: layers run sequentially. First required-layer failure stops execution and triggers revert (if file was modified) or reject.
CLI — gate.py
python3 scripts/gate.py \
--ranking ranking.json \ # REQUIRED: ranking artifact from discriminator
--execution execution.json \ # REQUIRED: execution artifact from executor
--state-root /path/to/state \ # default: lib/state_machine.DEFAULT_STATE_ROOT
--evaluation eval.json \ # optional: evaluator artifact (forwarded by orchestrator)
--layers schema,compile,review \ # optional: run only these layers (default: all 7)
--output receipt.json # default: auto-generated path| Param | Default | When to change |
|---|---|---|
--layers | all 7 | Use schema,compile for fast structural checks only |
--evaluation | None | Orchestrator passes this automatically when evaluator ran |
CLI — review.py (Human Review Queue)
# List pending human reviews
python3 scripts/review.py --state-root /path/to/state --list
# Complete a review
python3 scripts/review.py --state-root /path/to/state \
--complete review-cand-01-docs \
--decision approve \ # approve | reject
--reason "低风险文档变更，LGTM" \
--reviewer engineer-name # default: cli-user4-Way Decision Logic (after all required layers pass)
| Condition | Decision | Action |
|---|---|---|
accept_for_execution + low-risk docs/reference/guardrail + success | keep | File stays modified |
recommendation=reject | revert | Restore backup, append to veto log |
recommendation=hold OR non-auto-keep-eligible | pending_promote | Restore backup, create review request |
execution.status=unsupported | reject | No file change, log reason |
如果 HumanReviewGate 标记 needs_human=true，即使 keep eligible 也会升级为 pending_promote。
<example> 正确: gate 返回 pending_promote → 查审批队列 → 人工批准 $ python3 scripts/review.py --state-root ./state --list → ID: review-cand-01-docs Category: docs Risk: low Since: 2025-01-15T10:00:00Z $ python3 scripts/review.py --state-root ./state --complete review-cand-01-docs --decision approve --reason "confirmed safe" → Review review-cand-01-docs completed: approve </example>
<anti-example> 错误: gate 返回 revert 后仍然保留文件变更 → revert 时 gate 自动调用 restore_backup()，原文件已恢复。不要手动跳过。 </anti-example>
