## Checklist Results

| # | Criterion | Status | Evidence/Notes |
| --- | --- | --- | --- |
| 1 | Input/output messages match the corresponding Use Case's main success scenario step-for-step (Mandatory) | Pass | One message `countByFurColor` covers use case steps 1 to 4; the table justifies it. |
| 2 | Actor and System are treated strictly as black boxes (system shown as `:System`) (Mandatory) | Pass | Only Participant and :System appear. |
| 3 | Object creation/destruction of the System instance handled explicitly where relevant (Optional) | Pass | Lifecycle Notes: the instance lives for one run. |
| 4 | Return values are shown for operations that produce one, using dashed return arrows (Mandatory) | Pass | Dashed return arrows `summary` and `censusFileMissing`. |
| 5 | Alternate/exceptional flows are represented separately (or explicitly out of scope noted) (Mandatory) | Pass | The alternate flow 1a is the second diagram; 2a is stated to have no message. |
| 6 | Message names are verb phrases consistent with the use case's system responsibilities (Optional) | Pass | `countByFurColor` is a verb phrase. |
| 7 | Diagram references the specific Use Case (name and ID) it depicts (Mandatory) | Pass | Source Use Case names Count squirrels by fur colour ([UC-001]). |

## Language and Domain Results

| # | Criterion | Status | Evidence/Notes |
| --- | --- | --- | --- |
| 1 | The Metadata table has a `Language` row and a `Domain` row, and neither is a placeholder (Mandatory) | Pass | Metadata has `Language | en` and `Domain | it`. |
| 2 | `Language` is a BCP 47 code and `Domain` is a value from the registry's domain list (Mandatory) | Pass | `en` is a BCP 47 code; `it` is in the registry domain list. |
| 3 | The content (prose and table cells) is written in the stated language (Mandatory) | Pass | The system sequence diagram is written in English throughout. |
| 4 | The register matches the one the registry gives for the artifact type (Mandatory) | Pass | Professional register: messages, parameters and returns. |
| 5 | Domain terms are the PO terms of the domain's dictionary, with no synonyms (Mandatory) | Pass | Terms Participant, Census file, Squirrel sighting, Fur colour, Colour count, Summary and Summary file match [DICT-001]. |
| 6 | Metadata keys, section headings, IDs and statuses are in English (Mandatory) | Pass | Metadata keys, headings, IDs and statuses are English. |
| 7 | No translated twin (`<name>.<language>.md`) exists beside the document (Mandatory) | Pass | No translated twin exists in `docs/`. |
| 8 | A change of language or domain since the previous accepted version has a Version History row and was reviewed again (Mandatory) | Pass | First version; no earlier accepted language. |
| 9 | A reviewer competent in the domain, and in the language, has confirmed that the domain terms are used correctly (Mandatory) | Pass | Reviewer reads English and knows the software domain; no second reviewer needed. |
| 10 | Abbreviations are spelled out on first use, in the stated language (Optional) | Pass | Abbreviations are expanded on first use in the body (S-IDs and artifact IDs are framework labels). |
