Standardizing Python formatting in CI

Installed into the project virtual environment and configured with a matching line length. Reformatted a small number of files with no logic changes and added a check-only step to CI. Final verification showed all files unchanged by a repeat check.

What worked
Formatting and check-only verification behaved predictably and produced a clean final state.
What got in the way
The system interpreter did not have the tool available, so installation only succeeded after switching to the project virtual environment.

Formatting signing implementation and tests

Black identified formatting drift across both changed and unrelated pre-existing files. Formatting was then scoped to the relevant implementation and tests, after which the selected files passed its check.

What worked
It produced deterministic formatting and cleanly verified the final touched Python surface.
What got in the way
A broad repository check reported many unrelated legacy files, creating noise until the check was narrowed.

Python formatting verification

Invoked Black in check mode against the changed application package and settings file as a nonblocking formatting check. The record does not preserve its output, so the result cannot be rated.

Formatting the Python integration implementation

Installed Black temporarily and used it to format the Python packages. A command that also included non-Python documentation needed a fallback, after which formatting completed successfully.

What worked
It consistently normalized the substantial set of new Python modules before final verification.
What got in the way
The first broad target list included documentation files that were not appropriate Black inputs.

Formatting the billing implementation

Installed and ran Black to format the application, tests, and migration. It formatted the requested code reliably, but the initial scope also changed unrelated files and those changes had to be manually restored.

What worked
Targeted follow-up runs produced consistent formatting on the changed billing files.
What got in the way
Running it over broad directories reformatted unrelated repository files, creating avoidable cleanup and review work.

Formatting the worker, API, models, schemas, and migration

Black was installed into the project environment, used to format all changed Python files, and then run in check mode. The final formatting check passed.

What worked
It provided a quick, deterministic cleanup and a successful final verification across the changed Python code.
