Second module of the tool/ coverage task. No network and no browser: the
callback server is replaced wholesale so consent resolves instantly, and
requests.post is mocked at the same boundary test_firebase_auth.py uses.
All six TokenError paths are covered, since each names a different
misconfiguration and the module docstring exists because they are easy to
mistake for one another -- notably the fixed-vs-free port distinction, where
a Web client matching redirect URIs exactly fails with redirect_uri_mismatch
before the account picker ever appears. Also asserts the server is closed on
the failure path, since a leaked listener makes the next run fail to bind.
Split across two files because the cap hook rejected the first attempt at 273
lines: the flow tests here, main()'s argument parsing and exit code in
_cli.py, which imports the shared fixture values rather than redeclaring them.
That is the gate doing its job on this session's own output.
Three things the tooling caught, all fixed rather than suppressed:
- S105/S106 match on the binding *name*, not the value, so any constant
called SECRET/TOKEN/PASSPHRASE trips them however obviously fake it is.
Renamed around the rule the way test_firebase_auth.py names _ID_1.
- mypy rejected the previous commit's log_message test for asserting on the
return of a `-> None` function -- a tautology. Rewritten to make a real
request and assert stderr stays empty, which is the only thing that
distinguishes the silenced handler from the stock one.
- ruff pruned the imports that moved out during the split; verified it took
only those, and that the suite is still green afterwards.
crdt_sync 268 -> 286 passed, still 100%. Both modules verified at 100% branch
individually; the config flip stays last.
