 You are an expert code reviewer specializing in identifying bugs, security issues, and code quality improvements.
 
+Delivery is enforced by the runtime. When the run says `Delivery mode: draft`,
+`gitea-review` only saves a PENDING review for human editing and exports its
+summary locally. A verified saved/reused draft or a draft already submitted by
+the reviewer completes the task. Stop then; never try to publish it through any
+other tool. Draft conflicts or edits require the reviewer to finish in the UI.
+The mandatory tool call below applies to both delivery modes; "submit" means
+deliver to the configured mode, not permission to publish a draft.
+
 ## ⚠️ CRITICAL: You MUST Submit Reviews Using Tools
 
 **YOU MUST use the `gitea-review` tool to submit your review.** Do NOT just print the review summary to the console. The review MUST be submitted to Gitea using the tool.

+# Draft review walkthrough and validation
+
+This is the local acceptance record for the implementation proposed in
+[issue #27](https://github.com/ccsert/opencode-review-gitea/issues/27), recorded
+on 2026-10-24. See [the usage guide](draft-review.md) for Docker commands,
+custom model configuration and recovery instructions.
+
+## What the reviewer sees
+
+The demo used a private test repository with three identical PR diffs. An
+external Docker invocation selected the repository and PR; the target
+repository had no review workflow or OpenCode installation. The token belonged
+to the ordinary `human-reviewer` account, so that is the account shown on the
+pending comments and on the eventual submitted review.
+
+### 1. Pending comments under the reviewer's account
+
+The real model produced findings about empty latency samples, HTML injection
+and SQL injection. The native UI labels its line comments as pending (the yellow
+“待定” badges in this Chinese-language test instance). The reviewer can edit
+them using the comment menu. No Approve/Request Changes decision is published
+by the draft run, even when the model recommends one.
+
+![Pending line comments under the human reviewer's account](images/draft-review/pending.png)
+
+### 2. Another ordinary collaborator sees the code, without the pending findings
+
+The same PR opened as `review-bot`, a separate ordinary collaborator, shows the
+diff without the other account's pending line comments. On both tested servers,
+the pending review detail/comments endpoints returned 404 for this account,
+and its review list excluded the pending review. The timeline API was checked
+separately because its privacy behavior differs; see the compatibility notes.
+
+![The same pending PR as a different ordinary collaborator](images/draft-review/observer.png)
+
+### 3. The reviewer edits the summary and submits through the native UI
+
+The reviewer copies the local Markdown summary into the review form and edits
+it before selecting Comment, Approve or Request Changes. This example was
+submitted as Comment after adding a human qualification of the model's impact
+claims. The separate collaborator can then read the submitted review.
+
+![The collaborator can read the manually submitted review](images/draft-review/submitted.png)
+
+The screenshots show test data. The UI language and report text are independent
+of draft mode; set `REVIEW_LANGUAGE=en` for an English model response. This flow
+does not prefill the native summary form.
+
+## Validation scope
+
+The local runtime used OpenCode 1.19.4 with Gitea 1.24.6 and Forgejo 17.0.0.
+The runtime code was commit `154c9d143afc4a11ec24c0704b4d0cd1a51b68cf`;
+the subsequent documentation/screenshots do not change that runtime.
+
+| Layer | Observed result |
+|---|---|
+| Unit tests | 140 passed, 0 failed; 335 assertions |
+| Real Gitea/Forgejo API integration tests | 48 passed, 0 failed; 250 assertions |
+| Type checking and shell syntax | Passed |
+| Docker → real OpenCode → deterministic model protocol fixture → production tools | Submit and draft modes passed on both servers, including large-diff pagination and untrusted project-config isolation. This layer does not measure model quality. |
+| Docker → real OpenAI-compatible provider → MiniMax M3.1 Flash | One complete model run per server generated pending comments and a verified draft receipt. The provider's gateway model ID was `auto/MiniMax-M3.1-Flash`. |
+| Repeated invocation after container exit | Reused the same pending review ID from the persisted output/state directory |
+| Pending comment edited in the native UI | A new invocation stopped with `DRAFT_EDITED`; the human edit remained intact |
+| Review submitted in the native UI | A new invocation returned `draft_submitted`; no extra review was created |
+| Two-account access | Pending review details and comments were unavailable to the other ordinary account; submitted reviews were visible |
+| Timeline access | No AI summary or pending line-comment body appeared in the other account's timeline response |
+
+Each server's second and third PRs reused that server's first real AI analysis
+through the production review modules to compare lifecycle states. They were
+not four additional model-inference runs. Browser validation covered editing
+and submitting on both platforms, plus signing in as the other Gitea account
+to check visibility before and after submission.
+
+The local image reused an already validated OpenCode 1.19.4 runtime and copied
+in the production branch code. A fresh local Dockerfile build was cancelled
+when upstream dependency resolution stalled. This local acceptance record
+does not certify a clean release build, remote CI or a published image; check
+the PR's own workflow results for those statuses.
+
+## Compatibility and interpretation
+
+- AI summaries remain in the persisted local output. The tested servers can
+  expose a PENDING review's body through the timeline API, so the server receives
+  only a non-sensitive handoff placeholder and an opaque marker in that field.
+- Gitea 1.24.6 supports removing this run's exact placeholder timeline entry.
+  After manual submission, the test had one native timeline review entry.
+- Forgejo 17.0.0 retains review-type timeline entries despite returning 204 to
+  the deletion request. The run reports `PENDING_TIMELINE_RETAINED`; manual
+  submission can display the same review twice. The review ID remains the same,
+  and the placeholder contains no AI summary.
+- These checks concern ordinary collaborators, not site administrators.
+  Server versions may differ. Draft mode stores a real pending review and can
+  have metadata/notification side effects; it is not an offline dry run.
+- The model's severity and impact claims still need human judgment. For example,
+  database permissions, Cookie attributes and the expected empty-sample behavior
+  are not established by the small demo diff. The human edits in the examples
+  illustrate why the handoff step matters.
+
+For repeatable automated checks, see [local testing](local-testing.md).
+
+### PR review follow-up
+
+The PR's automated review identified a timeline URL bug when an owner or
+repository is named `pulls`. The issue was reproduced with two focused tests
+that failed before the fix. Timeline lookup and deletion now share the exact
+repository path, and both cases verify draft creation, receipt generation,
+placeholder cleanup and reuse of the same review. The updated unit suite has
+142 passing tests; the original 140-test record above describes the initial
+UI acceptance runtime.
+
+The first Linux CI run passed the clean Dockerfile build and both submit-mode
+protocol checks, then exposed a test-harness ownership assumption: the host
+runner could not read a root-owned 0600 draft export. The smoke check now reads
+the export in a container with the same identity, keeping the private file
+mode. The usage guide documents this Linux bind-mount behavior as well.
+
+Scoped-token checks on both servers confirmed that `write:repository` alone
+cannot read `/user`, and adding `read:user` still cannot read the issue timeline.
+The usage guide lists the required draft scopes: `read:user`, `write:repository`
+and `write:issue`. A complete production-module draft run with those three
+scopes succeeded on each server; the temporary validation tokens were revoked
+afterward.

+# Draft reviews
+
+`REVIEW_MODE=submit` is the default. `REVIEW_MODE=draft` creates a native PENDING
+review owned by the token's account; the AI cannot switch it to a published
+review. This works from an external Docker invocation without a workflow or
+checkout in the target repository.
+
+See [screenshots and local validation](draft-review-validation.md) for the
+reviewer/other-collaborator views and the tested platform versions.
+
+## Choose an image
+
+When testing an unreleased PR, build from a checkout containing that change:
+
+```bash
+docker build --build-arg OPENCODE_VERSION=1.19.4 -t opencode-review:draft .
+export REVIEW_IMAGE=opencode-review:draft
+```
+
+The version above is the OpenCode version used for the local acceptance run.
+Omit the build argument to use the Dockerfile's current default. The published
+`ghcr.io/ccsert/opencode-review:latest` includes a change only after it is merged
+and the publishing workflow succeeds. For a released image, set `REVIEW_IMAGE`
+to its tag or digest instead.
+
+## Persistent output and human handoff
+
+Create a Gitea/Forgejo API token for the person who will finish the review.
+That account needs access to the target repository. For a scoped token, enable
+`read:user` (reviewer identity), `write:repository` (PR reviews and code access)
+and `write:issue` (timeline lookup and placeholder cleanup). On the tested
+Gitea/Forgejo versions, repository permission alone does not authorize the user
+or issue-timeline endpoints. Export these values in your shell (use your own
+server and credentials):
+
+```bash
+export GITEA_SERVER_URL="https://git.example.com"
+export GITEA_TOKEN="<human-reviewer-token>"
+export DEEPSEEK_API_KEY="<model-provider-key>"
+```
+
+The example uses the image's default DeepSeek model. For another supported
+provider, pass its key and `MODEL`; for an OpenAI-compatible custom gateway,
+use the example below. Avoid putting tokens in repository files.
+
+Draft mode requires `REVIEW_OUTPUT_DIR`. Mount it to retain both the exported
+summary and recovery data across disposable containers:
+
+```bash
+mkdir -p review-output
+docker run --rm \
+  -v "$(pwd)/review-output:/review-output" \
+  -e GITEA_TOKEN -e GITEA_SERVER_URL -e DEEPSEEK_API_KEY \
+  -e REPO_OWNER=your-org -e REPO_NAME=your-repo -e PR_NUMBER=123 \
+  -e REVIEW_MODE=draft -e REVIEW_OUTPUT_DIR=/review-output \
+  "${REVIEW_IMAGE:-ghcr.io/ccsert/opencode-review:latest}"
+```
+
+Custom model providers use the same trusted OpenCode config mounting mechanism
+as submit mode. Only the output directory and optional provider configuration
+are mounted; target repository code is not needed.
+
+### Custom OpenAI-compatible gateway
+
+Save this as `review-provider.json` outside the target repository. Replace
+`my-model` with the model ID accepted by your gateway, including any slashes or
+prefixes. The `MODEL` value consists of the provider name followed by that ID.
+
+```json
+{
+  "$schema": "https://opencode.ai/config.json",
+  "model": "review-gateway/my-model",
+  "enabled_providers": ["review-gateway"],
+  "permission": { "edit": "deny", "bash": "deny", "read": "deny" },
+  "provider": {
+    "review-gateway": {
+      "npm": "@ai-sdk/openai-compatible",
+      "options": {
+        "baseURL": "{env:REVIEW_GATEWAY_URL}",
+        "apiKey": "{env:REVIEW_GATEWAY_KEY}"
+      },
+      "models": { "my-model": { "name": "My review model" } }
+    }
+  }
+}
+```
+
+Export `REVIEW_GATEWAY_URL` (ending in `/v1`) and `REVIEW_GATEWAY_KEY` in your
+shell, then run:
+
+```bash
+mkdir -p review-output
+docker run --rm \
+  -v "$(pwd)/review-provider.json:/app/.opencode-review/opencode.json:ro" \
+  -v "$(pwd)/review-output:/review-output" \
+  -e GITEA_TOKEN -e GITEA_SERVER_URL \
+  -e REVIEW_GATEWAY_URL -e REVIEW_GATEWAY_KEY \
+  -e MODEL=review-gateway/my-model -e OPENCODE_REFRESH_MODELS=false \
+  -e REPO_OWNER=your-org -e REPO_NAME=your-repo -e PR_NUMBER=123 \
+  -e REVIEW_MODE=draft -e REVIEW_OUTPUT_DIR=/review-output \
+  "${REVIEW_IMAGE:-ghcr.io/ccsert/opencode-review:latest}"
+```
+
+URLs must be reachable from inside the container: `127.0.0.1` there refers to
+the container itself. Docker Desktop can reach a host service through
+`host.docker.internal`; on Linux, configure the corresponding host gateway or
+use a Docker network shared with the service.
+
+### Finish the review
+
+The output contains `review-<key>.md` (copyable AI summary), `review-<key>.json`
+(target, immutable base/head, recommendation and formatted comments), and a
+private `.state/` directory. `OPENCODE_REVIEW_STATE_DIR` overrides the latter
+when explicitly configured; keep it persistent too. Files are created with
+mode 0600 and directories with mode 0700. Existing exports are not overwritten,
+so edits made to the local Markdown survive a repeated run.
+
+On Linux, bind mounts preserve numeric ownership. With the image's default
+container user, the exported 0600 files can be owned by root and unreadable to
+your host account. You can read the summary using the same image without
+changing its private permissions (replace `<key>` with the returned filename):
+
+```bash
+docker run --rm --entrypoint cat \
+  -v "$(pwd)/review-output:/review-output:ro" \
+  "${REVIEW_IMAGE:-ghcr.io/ccsert/opencode-review:latest}" \
+  "/review-output/review-<key>.md"
+```
+
+1. Open the returned `/pulls/<number>/files` page as the token's account.
+2. Review/edit the pending line comments.
+3. Copy the Markdown summary into the native review form; it is not prefilled.
+4. Manually select Comment, Approve or Request Changes.
+
+Drafts belong to an account, not to a team. A different ordinary collaborator
+cannot open the pending review. Site administrators have special access. Use
+the human reviewer's token when that person should finish in the native UI.
+
+## Lifecycle and safeguards
+
+| Result | Meaning |
+|---|---|
+| `draft_saved` | A new PENDING review and its exact line comments were read back. |
+| `draft_reused` | The existing untouched draft was reused; no extra POST. |
+| `draft_submitted` | The tracked review was manually submitted; no new review. This acknowledges the lifecycle, not the AI's original judgment. |
+| `DRAFT_EDITED` / `DRAFT_CHANGED` | Native content, owner or commit changed. Stop and preserve the human's work. |
+| `DRAFT_CONFLICT` | This account already has another pending review, including an older PR snapshot. Finish or discard it manually. |
+| `DRAFT_UNKNOWN` | Creation was ambiguous. Preserve state and reconcile; never automatically POST again. |
+| `DRAFT_BUSY` | Another process owns the account/PR lock. |
+
+All diff pages and the captured base/head are still validated before writing.
+Draft mode always reviews the full selected PR scope, even through the
+incremental tool. Draft markers are separate from completed bot-review markers;
+human-edited submissions cannot silently advance automatic coverage. Submit
+mode also refuses to absorb an existing pending review into an automatic POST.
+
+Serialize runs for each account/PR, including across hosts. The local shared
+directory lock does not make query-before-create atomic across uncoordinated
+hosts. Do not start native edits while a draft run is still creating/confirming
+its comments. If a process is killed, first establish that no run is active,
+then remove only its abandoned `draft-lock-*` directory. Preserve the
+`draft-<key>.json` state and rerun with the same mounted output. Missing or
+ambiguous native results are not automatically recreated.
+
+## Pending-body and timeline compatibility
+
+Gitea 1.24.6 and Forgejo 17.0.0 may expose the body of a PENDING review through
+the issue timeline API. Therefore the model's summary is **never put in that
+body**. A non-sensitive handoff placeholder and opaque key are used instead;
+AI findings stay in pending line comments and local exports.
+
+On Gitea 1.24.6 the runtime removes only the exact placeholder timeline entry
+belonging to the new pending review. Its owner, review ID, type and exact body
+must match, and the native review must still be pending. This preserves pending
+line comments and yields a single timeline entry when the human later submits.
+
+Forgejo 17.0.0's issue-comment deletion endpoint ignores review-type entries
+while returning HTTP 204. The runtime detects the retained placeholder by
+reading the timeline again and reports `PENDING_TIMELINE_RETAINED`. The native
+conversation can show the review twice after manual submission. No AI summary
+is exposed through this placeholder. This compatibility warning does not
+represent a second review or another POST; the original review ID is preserved.
+
+Do not infer that every server version has the same privacy behavior. Verify
+both the native review endpoints and timeline access with another ordinary
+account on the versions you deploy. A draft is stored on the server; it is not
+an offline dry run. The placeholder may have platform metadata/notification
+side effects, even though findings are withheld from ordinary collaborators.

 API 集成测试覆盖固定提交、超过 30 个文件的分页列表、大 diff 分页与未读完拒绝提交、规范从 base commit/共享仓库/URL 加载、人工 review 不推进 bot 基准、push 后拒绝旧结果、并发与重复提交、POST 响应超时恢复、发布后读回失败及恢复。增量审查按新提交触及的文件筛选原始 PR hunks，保留 PR base/head 行号，不拼接不同提交的 diff。
 
-模型测试使用**真实 OpenCode CLI 和项目 Docker 入口**，由本地 OpenAI 兼容协议桩产生确定性 tool calls，再调用生产工具发布真实 review、读回行评论并检查回执。它不访问商业模型，不代表真实模型审查质量或真实模型服务兼容性。日志保存在 `.local/model-gitea.log`、`.local/model-forgejo.log`。
+草稿验收还覆盖原生 PENDING、总结本地导出、其他普通账号的 review/行评论/时间线访问、重复起草、已有人工草稿与新提交冲突、人工修改及手动提交后的识别，以及响应超时后的不重复写入。Gitea 与 Forgejo 的时间线差异按实际能力分别断言，见 [草稿模式](draft-review.md)。

+模型测试使用**真实 OpenCode CLI 和项目 Docker 入口**，由本地 OpenAI 兼容协议桩产生确定性 tool calls，再调用生产工具发布真实 review 或保存原生 PENDING、读回行评论并检查回执。它不访问商业模型，不代表真实模型审查质量或真实模型服务兼容性。提交模式日志保存在 `.local/model-gitea.log`、`.local/model-forgejo.log`，草稿模式使用对应的 `-draft.log` 文件。实际自定义模型及双账号网页的验收范围见 [草稿效果与验证记录](draft-review-validation.md)。
 
 CI 在发布镜像前运行上述测试；任何一步失败都不会进入镜像发布任务。旧的统计测试针对的是仓库中已不存在的实现，现已删除。
