+- Scope: full review (Brief format; MIL-010 task 1)
+- Language and domain: n/a (technical type)
+- Language reviewer: none
+- Mode: autonomous, not independent (the reviewer is `AI as stand-in for S01`; the user accepted the plan in chat on 2026-10-14)

+## Checklist Results
+
+| # | Criterion | Status | Evidence/Notes |
+| --- | --- | --- | --- |
+| 1 | Consists of a single, concise paragraph summarizing only the primary success scenario | Pass | One paragraph: push, count, read the report, publish three badges, README shows them. |
+| 2 | Written as an informal multi-paragraph narrative; may mention some alternate flows without formal structure | N-A | Format is Brief. |
+| 3 | All standard sections are present: actors, preconditions, postconditions, main success scenario, alternative/exception flows | N-A | Format is Brief; actor, stakeholders, pre- and postconditions and the paragraph are present. |
+| 4 | Preconditions and postconditions are explicitly defined | Pass | Both are stated; the postcondition says that only the badges change. |
+| 5 | Primary actor is explicitly stated | Pass | Software Engineer. |
+| 6 | Stakeholders and their interests are stated | Pass | S02 and S05 with an interest each. |
+| 7 | Main success scenario is written as clear, numbered steps | N-A | Format is Brief. |
+| 8 | Alternative/exception flows correctly reference `<<include>>`/`<<extend>>` use cases where relevant, per UML 2.5.1 | N-A | None in a Brief. |
+| 9 | Explicit business rules are captured per step where applicable, rather than embedded loosely in narrative text | N-A | No steps in a Brief. |
+| 10 | Naming of actors and use case title is consistent with the corresponding Use Case Diagram and User Stories | Pass | Title and actor equal UCD-001 (RC-071); the Stories line lists US-001.18 to US-001.20, which exist (RC-070). |
+| 11 | Scope/level (e.g. summary, user-goal, subfunction) is explicitly stated | Pass | Scope Reusable Workflow Collection, user-goal level. |
+| 12 | Use case is written from the actor's goal perspective, free of UI or implementation detail | Pass | Goal wording; no tool, file name or format of a report is named. |
+
+## Overall Verdict
+
+Go - all applicable criteria pass. The AI records the decision as stand-in for S01; there is no independent reader and the decision stays open to challenge in the run summary.

+| 1 | Follows INVEST criteria (Independent, Negotiable, Valuable, Estimable, Small, Testable) | Pass | US-001.18 to US-001.20 are independent of each other, each states one value and has checkable criteria; the INVEST section of US-001 now counts twenty stories. |
+| 2 | Written in "As a / I want / So that" form | Pass | All three stories. |

+| 5 | Story is sized to fit within a single iteration | Pass | Each says: fits one iteration. |

+**Format:** Brief
+
+**Title:** Show Code Metrics and Coverage Badges
+**Scope:** Reusable Workflow Collection
+**Level:** user-goal
+**Primary Actor:** Software Engineer
+**Stakeholders:** S02, S05 (interests below)
+**Stories:** US-001.18, US-001.19, US-001.20
+
+## Brief
+
+A Software Engineer pushes a change to a repository that calls the shared code-metrics workflow. The workflow counts the code files and the lines of code (without comment and blank lines), reads the coverage report the repository supplies, and publishes three badges: the number of code files, the number of lines of code and the coverage. The repository's README shows the badges, and they show the numbers of the latest push.
+
+**Stakeholder interests**
+
+- S02 — the size and the coverage of the code are visible at a glance, without a service outside the instance, and a wrong or missing report is reported instead of shown as a number
+- S05 — the counting rules and the badge contract are defined once and change through a reviewed release
+
+**Preconditions:** The repository is onboarded and the shared workflow is available through reusable workflow delivery; a coverage badge needs a coverage report that the repository's own tests have produced.
+
+**Postconditions (success guarantee):** The three badges show the numbers of the pushed revision, nothing but the badges is changed in the repository, and a run whose numbers are unchanged changes nothing.

+### US-001.18 — The size of the code is visible as badges
+
+**As a** Software Engineer, **I want** badges that show the number of code files and the number of lines of code without comment and blank lines, **so that** the size of the project is visible in its README without a service outside the instance.
+
+**Acceptance Criteria**
+
+- Given a repository that calls the shared code-metrics workflow, when a change is pushed, then a badge for the code files and a badge for the lines of code show the numbers of that revision.
+- Given a file with a comment line, a blank line and a code line, when the lines are counted, then only the code line is counted as a line of code.
+- Given a repository without a file of a supported language, when the workflow runs, then it passes with a notice and the badges show zero.

+### US-001.19 — The coverage is visible as a badge
+
+**As a** Software Engineer, **I want** a badge that shows how much of the code my tests cover, **so that** a drop in coverage is seen as soon as it is pushed.
+
+**Acceptance Criteria**
+
+- Given a repository that supplies a coverage report, when a change is pushed, then a coverage badge shows the percentage of the report, and its colour follows the thresholds of the contract.
+- Given a coverage report that is missing or that cannot be read, when the workflow runs, then it fails with a `[configuration]` message that names the report file and no coverage badge is changed.
+- Given a repository that supplies no coverage report, when the workflow runs, then it passes with a notice and publishes no coverage badge.

+### US-001.20 — A run with unchanged numbers changes nothing
+
+**As a** Software Engineer, **I want** the workflow to commit nothing when the numbers did not change, **so that** the history of the repository is not filled with badge commits.
+
+**Acceptance Criteria**
+
+- Given a push after which none of the three badges would differ, when the workflow runs, then no commit is made.
+- Given a push after which a number changed, when the workflow runs, then one commit changes only the badge files, and the workflow does not start again from that commit.
