# PR#61: one change without a statement no longer drops the whole PR document check

## The Problem

Since PR#47, an economy model summarizes the diff as a list of changes, and Jev compares the PR document with it.
werkrevisor refuses the whole summary if one change has no statement.
In the review of PR#58, MiniMax M3 left out one statement, so the PR document was not checked at all.

On 2026-10-08 the operator selected the risk template `jvm-spring-backend` for werkator on mih09,
but config/werkator.toml in this repository does not name it yet.

## Non-Goals

- No change of the questions of the PR document check.
- No change of config/werkprobe.toml: its host block on mih09 differs on purpose, e.g. in the model.

## The Scenarios

### Feature: the PR document check keeps the usable part of a summary

#### Scenario#61.01: a change without a statement is left out, the others are compared

So that one sloppy entry of the economy model does not drop the whole check.

- **Given** a summary with two changes, and one of them has no statement
- **When** werkrevisor reads the summary
- **Then** it keeps the change with a statement
  - **and** Jev compares the PR document with it

##### Verified by

- [test_doccheck: test_a_change_without_a_statement_is_left_out_the_others_are_compared](../../tests/test_doccheck.py)

#### Scenario#61.02: a summary without any usable change is still refused

So that a comparison never runs against nothing.

- **Given** a summary whose changes all lack a statement
- **When** werkrevisor reads the summary
- **Then** the check is left out with a hint

##### Verified by

- [test_doccheck: test_a_summary_without_any_usable_change_is_still_refused](../../tests/test_doccheck.py)

## The Solution

- `doccheck.parse_summary` leaves out the changes without a text statement and refuses only a summary without any left.
- config/werkator.toml selects `risk_template = "jvm-spring-backend"`, as the host block on mih09 does.
- docs/werkrevisor.werkbaum marks the planned fix as done, and the risk categories as live.
- werkrevisor 0.28.1.

## Prerequisite PRs

- PR#60: werkrevisor 0.28.0, merged.
