Three low-severity findings from Codex on the 1.0.0-37 split:
1. Trim dead package-level imports in routes/__init__.py — only
`poller` was actually used; auth/burnin/mailer/settings_store
were the exact shadowing footgun the absolute sub-router
imports work around. Reword the comment block to match.
2. Thread `operator` through smart_start + smart_cancel.
Previously the JS client sent it but the server ignored it;
add audit_events rows (smart_test_start / smart_test_cancel)
so the field is actually meaningful.
3. New tests/test_routes_resolution.py — guards two historical
regressions: /api/v1/burnin/export.csv must register before
/{job_id} (FastAPI int-coerce 422 trap) and the mailer
back-compat shim `from app.routes import _fetch_drives_for_template`
must keep importing. Plus a sub-router enumeration test that
catches missed include_router calls in future splits.
Largest routes/ slice yet — drives.py (8 endpoints) and burnin.py
(4 endpoints). Drives helpers live in _drives_helpers.py so the
dashboard SSE handler in routes/__init__.py and mailer.py can both
keep using them via re-export.
routes/__init__.py shrinks from 815 → 163 LoC; only the dashboard /
and /sse/drives stream remain there. Routes split is now functionally
complete: 12 files, ~1800 LoC distributed by feature.
