# Gateflow

Gateflow 只定义单个 `work unit` 的流程和 gate。work unit 可以是 feature、issue、bug fix、migration、refactor、
schema/public contract change 或 architecture-sensitive task。

## Core Principles

- 先看代码和事实,再判断 work unit 是否成立。
- 进入 plan 前,先用通俗语言向用户确认目标、非目标、边界和成功信号。
- 只做当前 work unit 需要的设计;不得引入无当前需求、真实风险或明确扩展压力支撑的过度设计。
- 每个 gate 都必须有 artifact、decision、validation 或明确说明;conversation-only 结果不足以通过 gate。
- draft PR gate 自动推进到 `draft-PR-pass`;merge、approve、mark ready for review、request reviewers、delete branch、
  对外 comment、创建/修改外部 issue 仍需用户额外授权。

## Invocation

典型调用:

```text
使用 $gateflow 开发 <work-unit>。
```

可选参数:

```text
使用 $gateflow design_doc=<path> base_ref=<ref> 开发 <work-unit>。
```

如果传入 `design_doc`,它是当前 work unit 的设计依据之一。若未传入,则以用户需求和代码事实为准。

## Preflight

任何 discussion、plan 或文件修改前,先检查:

```text
git branch --show-current
git status --short
```

如果当前 branch 是 `main`、`master`、`develop`、`release/*` 或项目定义的 protected trunk branch,先停下来让用户确认创建
工作分支。若 branch、dirty changes 或 scope ownership 不清,也先停下来问用户。

## Goal Confirmation

进入 plan 前必须完成 goal confirmation:

- 读取需求、design document(如有)和相关代码;
- 从第一性原理判断 work unit 是否成立;
- 复述目标、动机、成功信号、非目标、scope boundary;
- 说明直接代码证据;
- 说明本轮不会做的过度设计;
- 列出 blocking open questions(如有)。

用户确认后才能进入 `plan`。如果目标不成立、范围过大、动机不足或关键约束缺失,先 discussion,不进入 implementation。

## Gate Order

固定顺序:

```text
goal confirmation
-> plan
-> plan review
-> fix
-> re-review
-> accepted plan commit
-> implementation
-> code review
-> fix
-> re-review
-> accepted slice commit
-> aggregate deepreview
-> fix
-> re-review
-> accepted deepreview commit
-> ready-to-open-draft-PR
-> push
-> create draft PR
-> PR review
-> fix
-> re-review
-> accepted PR review commit
-> push
-> draft-PR-pass
-> final closeout
```

`plan review` gate 必须使用 `planreview` skill;`code review`、`aggregate deepreview` 和 `PR review` gates 必须使用 `deepreview` skill。

多 slice 时重复:

```text
implementation -> code review -> fix -> re-review -> accepted slice commit
```

直到所有 approved slices 完成。

## Stop Conditions

除以下情况外,用户确认目标后自动推进:

- blocking open question 影响 scope、architecture、contract、schema、file ownership、state transition、implementation strategy、
  test expectation 或 user-visible behavior;
- branch、dirty changes、file ownership、commit scope 不清,无法安全创建 checkpoint;
- validation failure、unclassified residual risk、deferred finding 或 missing artifact 需要用户决策;
- 需要 merge、approve、mark ready for review、request reviewers、delete branch、对外 comment 或创建/修改外部 issue。

## Plan Gate

plan 必须 code-generation-ready,即可以直接指导实现,不需要重新设计方案、发明契约、猜 file ownership、猜 state transition
或决定 test scope。

plan 必须包含:

- goal / motivation / success signal;
- non-goals / scope boundary;
- design document alignment(如有);
- first-principles judgment and direct code evidence;
- affected files/modules;
- contract/schema/state-machine/public-interface changes;
- implementation decisions;
- small implementation slices;
- tests/validation commands and expected assertions;
- docs decision;
- risks/open questions;
- completion report format。

plan 必须显式说明为什么当前方案没有过度设计。

## Slice Gate

每个 slice 必须足够小,适合一次 implementation pass 和一次 review pass。每个 slice 必须写清:

- id/name、objective、expected outcome;
- allowed files/modules;
- prerequisites/dependencies;
- exact allowed changes;
- functions/classes/types、call paths、data flow、state transitions、error handling、invariants;
- non-goals;
- tests/validation commands and expected assertions;
- completion signal and stop condition。

implementation 只能做当前 approved slice,除非 approved plan 明确允许一次做多个 slice。

## Review Gate

review / re-review 必须 evidence-based,并产出 durable artifact。finding 必须能被裁决为:

- `accepted`
- `rejected-with-reason`
- `deferred-with-owner`
- `needs-more-evidence`

fix/re-review 最终状态只用:

- `未修复`
- `已修复`
- `部分修复`
- `证据失效`

review gate 通过条件:

- review artifact 已记录 artifact path;
- accepted findings 都有 fix/re-review 状态;
- re-review 已回写或列出最终 finding 状态;
- 没有 blocking open question;
- residual risks 已分类。

## Residual Risks

每个 implementation/fix/review artifact 必须列出 residual risks 和 uncovered areas。每个 residual risk 必须分类为:

- fixed in current slice;
- covered by later approved slice;
- assigned to later work unit;
- tracked by existing issue;
- requiring new issue or explicit user decision。

存在 unclassified residual risk 时,不得关闭 slice、review loop、aggregate deepreview loop、PR gate 或 final closeout。

## Artifacts

必要 artifacts:

- plan artifact;
- plan review / re-review artifact;
- implementation artifact for each slice;
- code review / re-review artifact for each slice;
- fix artifact when fixes occur;
- aggregate deepreview / re-review artifact;
- PR review / re-review artifact;
- final closeout summary。

artifact 必须记录 gate、work unit、scope、changed files 或 reviewed target、decisions/findings、validation、docs decision、
residual risks、completion status 和 artifact path。

## Commits

review loop 通过、artifact 完整且没有 blocking open question 后,自动创建 protected local commit:

```text
gateflow: accept plan for <work-unit>
gateflow: accept <work-unit> <slice-id>
gateflow: accept deepreview for <work-unit>
gateflow: accept PR review for <work-unit>
```

commit 前必须确认 branch 不是 protected trunk,检查 `git status`,只 stage 当前 gate 相关文件,避免 unrelated dirty changes。

## Draft PR Gate

`ready-to-open-draft-PR` 前确认:

- branch 只包含当前 work unit intended commits;
- all approved slices 完成并有 accepted slice commits;
- aggregate deepreview 已执行,accepted findings 已修复并 re-reviewed;
- accepted deepreview commit 已创建;
- tests/type checks 已运行或失败已说明;
- docs decision 已完成;
- deferred findings/residual risks 有 owner/destination;
- draft PR summary 匹配真实代码,不把 future work 写成已完成。

到达 `ready-to-open-draft-PR` 后自动:

```text
push
-> create draft PR
-> PR review
-> fix
-> re-review
-> accepted PR review commit
-> push
-> draft-PR-pass
```

PR review 有 accepted findings 时,必须自动修复并 re-review。PR review 若无 accepted findings,也必须提交 PR review artifact /
pass evidence 并 push。

## Final Closeout

`draft-PR-pass` 后输出 final closeout:

- what changed;
- what was verified;
- docs updates;
- finding status;
- remaining risks / owners;
- draft PR URL;
- next entry point。
