7-layer mechanical quality gate: any required layer fail = reject/revert.
improvement-discriminatorimprovement-executorimprovement-learner| 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.
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 |

| 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。
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
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。
