Build failing on PR #37: ruff format check fails on Documentation/event-sources.md

[cratis-direct]

What's wrong

The "Build" workflow is failing on PR #37 (feature/registered-event-sources), run
https://github.com/Cratis/Chronicle.Python/actions/runs/37098674267 — the "Check formatting"
step (ruff format --check .) fails because the Python code block in
Documentation/event-sources.md has an unwrapped import statement and an
EventStreamDefinition(...) call that exceed the project's 120-character line length
([tool.ruff] line-length = 120) and are not formatted per ruff's style.

Reproduced locally against feature/registered-event-sources (078435676d3359e252eaeb6c32eb6061f6b860db)
with ruff 0.16.10:

unformatted: File would be reformatted
  --> Documentation/event-sources.md:12:27

The fix

Running ruff format Documentation/event-sources.md produces this diff, after which
ruff format --check . (190 files), ruff check ., mypy src, and pytest (14 passed)
all pass clean on that branch:

diff --git a/Documentation/event-sources.md b/Documentation/event-sources.md
index a177a46..8b18b03 100644

+    ConcurrencyDimensions,

 )
 
 account = EventSourceDefinition(
     "Account",
     concurrency=ConcurrencyDimensions.EVENT_SOURCE_ID,

+        ),
+    ),
 )
 routing = resolve_routing({account.name: account}, "Account", "Transactions")

Why this is an issue and not a PR/push

The fix is a single-file, mechanical ruff format run with no semantic change, verified
against the feature/registered-event-sources branch. This session's git/GitHub write
permissions (git push, gh pr) are gated behind manual approval that wasn't available
here, so I could not push the fix commit to the PR branch or open a pull request. @einari —
feel free to run ruff format Documentation/event-sources.md on your branch (or apply the
diff above) to unblock the Build workflow on #37.

Thanks for opening this - it has been received and will be looked at.
