+# Gatekeep
+
+AI-assisted PR review for **your own repos**: parallel multi-model review across **providers**, fail-closed PR risk tiers, agreed-only inline findings, blocking security check.
+
+**中文说明：** [README.zh-CN.md](./README.zh-CN.md)
+
+## Install (remote `uses:`)
+
+```yaml
+# .github/workflows/gatekeep.yml  ← must live under .github/workflows/ on Gitea/GitHub
+- uses: actions/checkout@v4
+- uses: https://git.potatolab.uk/layue13/gatekeep@main
+  # placeholder: uses: https://git.example.com/OWNER/gatekeep@v1
+  env:
+    # Names must match providers.yaml `key` — FREE-FORM (no required gatekeep_ prefix)
+    OPENROUTER_API_KEY: ${{ secrets.OPENROUTER_API_KEY }}
+  with:
+    github-token: ${{ secrets.GITHUB_TOKEN }}
+```
+
+### Dogfood (this repo)
+
+`layue13/gatekeep` reviews **its own** PRs via [`.github/workflows/gatekeep-pr.yml`](.github/workflows/gatekeep-pr.yml) with `uses: ./` and `secrets.OPENROUTER_API_KEY`. Open a PR against `main` to see a review (Gitea Actions must have a runner — same pool as other `layue13` repos).
+
+Allowlists / Gitea-on-github.com limitations: [`docs/remote-uses.md`](docs/remote-uses.md).
+
+## Providers YAML
+
+```yaml
+providers:
+  openrouter:                 # only include providers you configure
+    key: OPENROUTER_API_KEY   # free-form secret/env name — pick any
+    protocol: openai          # openai | openai-completions | openai-responses | anthropic
+    # base_url: optional (defaults exist for openrouter / anthropic / openai)
+    models:
+      - google/gemma-4-31b-it:free
+      - google/gemma-4-26b-a4b-it:free
+      - cohere/north-mini-code:free
+      - nvidia/nemotron-3-nano-omni-30b-a3b-reasoning:free
+```
+
+| Field | Meaning |
+| --- | --- |
+| `key` | **Free-form** name of the GitHub secret / env var holding the API key. **No** required `gatekeep_` prefix. |
+| `protocol` | `openai` \| `openai-completions` \| `openai-responses` \| `anthropic` |
+| `models` | Names to use (validated against the provider’s model list API at runtime) |
+| `base_url` | Optional; known provider ids get defaults |
+
+Mix providers in one review by listing several entries. Secrets are read from the **workflow step `env`** using each entry’s `key` name.
+
+Example suggestion only (still free-form): `key: gatekeep_openrouter` is fine if you named your secret that — not required.
+
+## Finding format
+
+**Severity** (Critical→Low) + **where** (`path:line`) + **why it matters**. Inline only when ≥2 models agree.
+
+## PR risk tiers
+
+| Tier | Humans | Auto-merge |
+| --- | --- | --- |
+| low | 0 after Gatekeep + security green | If kill switch on |
+| medium | 1 | No |
+| high | 2 | No |
+
+## Optional consumer config
+
+`config-dir: .github/gatekeep` with your `providers.yaml`. Omit to use Action `defaults/providers.yaml`.
+
+## Layout
+
+```
+action.yml
+scripts/            # resolve-providers.py, call-model.sh, …
+defaults/providers.yaml
+config/providers.yaml   # example override

+# Gatekeep
+
+AI 辅助的 PR 审查 Action：多模型并行投票、按严重级别输出可扫读的结论，适合自己的仓库。
+
+## 它做什么
+
+- 对每个 PR 并行调用 **2–3 个模型**（**可来自不同供应商**），**仅当多个模型达成一致**时发 inline 评论。
+- 每条结论明确写出：**严重级别**、**代码位置**、**为什么重要**。
+- 汇总评论给出 PR **风险档**（low / medium / high）；安全相关可阻断合并。
+- 不提供 CodeRabbit 式聊天 / `@命令`。
+
+## 远程引用（推荐）
+
+工作流文件必须放在 **`.github/workflows/`**（Gitea / GitHub 都认这个路径）。
+
+```yaml
+- uses: actions/checkout@v4
+- uses: https://git.potatolab.uk/layue13/gatekeep@main
+  # 占位：uses: https://git.example.com/OWNER/gatekeep@v1
+  env:
+    # 必须与 providers.yaml 里的 key 同名（自由命名，无强制 gatekeep_ 前缀）
+    OPENROUTER_API_KEY: ${{ secrets.OPENROUTER_API_KEY }}
+  with:
+    github-token: ${{ secrets.GITHUB_TOKEN }}
+```
+
+### 自审（本仓库 dogfood）
+
+`layue13/gatekeep` 用 [`.github/workflows/gatekeep-pr.yml`](.github/workflows/gatekeep-pr.yml) 对本仓库 PR 跑 Gatekeep：`uses: ./` + `secrets.OPENROUTER_API_KEY`。向 `main` 开 PR 即可触发（需有可用的 Gitea Actions runner）。
+
+github.com runner 若不允许非 github.com Action 源，见 `docs/remote-uses.md`。
+
+## 多供应商（providers.yaml）
+
+```yaml
+providers:
+  openrouter:
+    key: OPENROUTER_API_KEY   # 自由命名 — 任意 secret/环境变量名
+    protocol: openai          # openai | openai-completions | openai-responses | anthropic
+    models:
+      - google/gemma-4-31b-it:free
+      - google/gemma-4-26b-a4b-it:free
+      - cohere/north-mini-code:free
+      - nvidia/nemotron-3-nano-omni-30b-a3b-reasoning:free
+```
+
+- **`key`：自由命名**，**不要**要求必须 `gatekeep_` 前缀（你也可以叫 `gatekeep_openrouter`，只是举例）。
+- 每个供应商只需：`key` + `protocol`（`base_url` / `models` 按需；已知 id 有默认 base_url）。
+- **不内置死模型清单**；启动时拉取供应商模型列表并校验名字。
+- 可混用多个供应商；只写你真正配置了的条目。
+
+## 输入面
+
+| 项 | 含义 |
+| --- | --- |
+| `key` | Secret / 环境变量名（自由） |
+| `protocol` | `openai` / `openai-completions` / `openai-responses` / `anthropic` |
+| `models` | 参与并行审查的模型名 |
+| step `env` | 把 `key` 同名的 secret 注入环境 |
+| `github-token` | 发评论 / checks |
+
+## 混用示例
+
+```yaml
+- uses: https://git.potatolab.uk/layue13/gatekeep@main
+  env:
+    OPENROUTER_API_KEY: ${{ secrets.OPENROUTER_API_KEY }}
+    ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
+  with:
+    github-token: ${{ secrets.GITHUB_TOKEN }}
+    config-dir: .github/gatekeep   # 内含 providers.yaml，见 config/providers.yaml
+```
+
+## 风险档
+
+| 档 | 人工 |
+| --- | --- |
+| low | 0（审查与安全绿后；kill switch 可自动合并） |
+| medium | 1 人（Bot 不能顶替） |
+| high | 2 人 |
+
+## 更多
+

+# Deploy slots (stub — later)

+Gatekeep’s PR Action does **not** perform production rollback. Ops keeps two slots:
+
+| Slot | Role |
+| --- | --- |
+| `current` / `active` | What players/users hit now |
+| `previous` | Last known-good artifact for one-command swap |
+
+**v1 note only:** wire symlink or compose services outside this Action; record `previous_good_sha` on every deploy; PR template “How to revert” points operators here. Auto-rollback stays human-confirm by default except crash-loop burn-in (see Project rollback design).
+
+Artifact retention for review/verify jobs uses `actions/upload-artifact` (`gatekeep-last-good-<run_id>`, 14 days) — that is **CI evidence**, not the production slot.

+# Dogfood — Gatekeep reviews Gatekeep
+
+The Action repo itself runs Gatekeep on its own pull requests.

+| --- | --- |
+| Live workflow | `.github/workflows/gatekeep-pr.yml` |

+| Trigger | `pull_request` (non-draft) + `workflow_dispatch` |
+
+## How to see a review
+
+1. Branch off `main`, make a tiny change, open a PR on https://git.potatolab.uk/layue13/gatekeep
+2. Wait for the **Gatekeep** workflow (same Actions runner pool as other `layue13` repos)
+3. Look for the summary comment `<!-- gatekeep-review -->` on the PR
+
+Consumer sample workflows remain under top-level `workflows/` for copy-paste into *other* repos’ `.github/workflows/`.

+# Remote `uses:` — limitations & workarounds
+
+Gatekeep is a **self-contained composite Action** (`action.yml` at repo root + `scripts/` + `defaults/`). Consumers should prefer:
+
+```yaml
+uses: https://git.example.com/OWNER/gatekeep@v1
+# Project example:
+uses: https://git.potatolab.uk/layue13/gatekeep@main
+```
+
+No copy of Action sources into the consumer repo is required. Optional `.github/gatekeep/` overrides still work via `config-dir`.
+
+## What must be true
+
+| Requirement | Notes |
+| --- | --- |
+| Runner can fetch the Action git repo | Network + credentials if the Action repo is private |
+| Runner can reach OpenRouter | `OPENROUTER_API_KEY` secret |
+| `GITHUB_TOKEN` permissions | `pull-requests: write`, `checks: write` (see sample workflow) |
+| Org / repo Actions policy | External Actions allowed |
+
+## GitHub.com-hosted consumers + Gitea-hosted Action
+
+**Honest status:** GitHub Actions’ first-class `uses: owner/repo@ref` syntax is for **github.com**. Full URL `uses: https://…@ref` is documented for public Actions, but **enterprise / org allowlists** often restrict non-`github.com` Action sources. Behavior can also differ by plan and policy version.
+
+If `uses: https://git.potatolab.uk/layue13/gatekeep@main` fails on github.com runners with an allowlist / “not permitted” / fetch error:
+
+### Workaround A — GitHub mirror (recommended)
+
+1. Mirror `layue13/gatekeep` to a github.com repo you control (e.g. `your-org/gatekeep`).
+2. Point consumers at:
+   ```yaml
+   uses: your-org/gatekeep@main
+   # or: uses: your-org/gatekeep@v1
+   ```
+3. Keep the Gitea repo as source of truth; sync tags on release.
+
+### Workaround B — Vendor checkout (still no Marketplace)
+
+If remotes are fully blocked, checkout Gatekeep into the job and run the composite via local path:
+
+```yaml
+- uses: actions/checkout@v4
+  with:
+    repository: layue13/gatekeep   # or mirror
+    # For Gitea, use a custom remote + token:
+    # (or actions/checkout with sparse / git mirror step)
+    path: .gatekeep-action
+    ref: main
+- uses: ./.gatekeep-action
+  with:
+    github-token: ${{ secrets.GITHUB_TOKEN }}
+    openrouter-api-key: ${{ secrets.OPENROUTER_API_KEY }}
+```
+
+For a pure Gitea URL when `actions/checkout` only speaks github.com, use an explicit `git clone` step with a deploy token, then `uses: ./.gatekeep-action`.
+
+### Workaround C — Copy-in (appendix)
+
+Copy Action files into `.github/actions/gatekeep` (see README appendix). Same runtime; more drift risk.
+
+## Gitea / Forgejo Actions runners
+
+If the **consumer** also runs on Gitea Actions (not GitHub-hosted), use that forge’s documented `uses:` / local action syntax. Paths remain `github.action_path`-relative so the same Action tree works once the runner can resolve it.
+
+## Secrets never travel with the Action
+
+Remote fetch does **not** include consumer secrets. Always set `OPENROUTER_API_KEY` (and any forge token for private Action clones) on the **consumer** repo/org.

+## Summary
+
+<!-- What and why. Risk is discovered by Gatekeep — do not rubber-stamp "low risk" here. -->
+
+## Testing notes
+
+- [ ] Discovered build/test entry points run locally or in CI (paste command / job link)
+- [ ] Benchmarks vs thresholds (fps / startup / memory) if behavior-sensitive — or N/A
+- [ ] Client-visible paths: noted if **not** verified on GitHub-hosted runners
+
+Commands / evidence:
+
+```
+<!-- e.g. npm test, make verify, artifact URL from gatekeep-last-good-* -->
+```
+
+## Risk (author hint — Gatekeep may raise the PR tier)
+
+Author self-assessment (optional): low / medium / high
+
+Sensitive paths touched? (auth, billing, `.github/workflows`, secrets, release): yes / no
+
+<!-- Gatekeep findings lead with severity (Critical→Low) + exact location + why it matters.
+     No @-mention chat commands — fix or dismiss: dismissed: <reason> -->
+
+## How to revert
+
+Rollback speed is the load-bearing wall. Fill this in before merge.
+
+1. **One-step revert:** `git revert <merge-sha>` (or GitHub "Revert") then merge the revert PR.
+2. **Artifact / slot rollback:** point `active` at previous known-good artifact (see Gatekeep deploy-slots note); restart.
+3. **Feature flag / kill switch:** <!-- name → GATEKEEP_MERGE_ENABLED=false also stops AI auto-merge -->
+4. **Data / world migrations:** <!-- none | forward-only | script path -->
+5. **Owner if this causes an incident:** <!-- @owner → file gatekeep-incident -->
+
+If this change is hard to revert, treat it as **high** risk and get the required human approvals.
