用证据驱动的窄范围执行循环完成单一任务并更新追踪器

用一套证据驱动的小范围执行循环去完成单项任务：只改一点、验证、收集证据、把状态写回 tracker。要执行任务队列的下一项、验证某个改动或从已准备好的队列继续时就用它。特点是严格“一次只做一件、用对的证据证明”的闭环，适合 MVP 和可追溯的开发节奏。

# Build Right Execution

Use this skill after pre-execution work has produced product truth, MVP scope,
operating rules, and an executable task queue.

Core rule:

```text
Do one task.
Prove the current state.
Change narrowly.
Verify with the right evidence.
Update the tracker.
Then move to the next task.
```

## Required Reading

- Always read `references/workflow.md` before acting.
- Read `references/gates.md` before task selection, after task intake, and
  before advancing to another task.
- Read `references/review-and-delegation.md` only when review triggers apply,
  subagent review is useful, or broad evidence/tracker changes are touched.
- Read `references/evidence-contract.md` before
