Push builds have been RED on the lint step since ~build 209 from accumulated
formatting drift. This is the mechanical cleanup: ruff format + ruff --fix
(UP038 isinstance unions, SIM105 contextlib.suppress, UP031 f-strings, SIM115
tempfile context manager), shfmt -i 2 -ci, nixpkgs-fmt/statix/deadnix (merged
attrsets, dropped unused lib args), yamllint, and shell quoting fixes in
tests/lasuite-docs/setup_custom_tests.sh. No behaviour changes intended;
lint: PASS, unit tests: 138 passed.
Proactively addresses the Adversary's pre-claim recon (f7c5681): since the F2-12 fix replaces abra's
converge monitor (-c) with the harness's own wait, prove the replacement genuinely FAILS a broken
convergence (non-vacuous), not just passes a slow one. 5 deterministic tests (fake clock, no deploy):
- wait_ready_probes RAISES TimeoutError when the READY_PROBE never returns 200 (collabora wedged).
- wait_ready_probes returns when it reaches 200; no-op without a READY_PROBE.
- wait_healthy RAISES when services never converge, and when converged-but-never-serving.
Run: cc-ci-run -m pytest tests/unit/test_f212_upgrade_convergence.py -q → 5 passed.
