Google Secret Manager bills every enabled version, per replica, every hour - even when your compute is off. A deploy step with no idempotent upsert quietly stacked ~470 duplicate secret versions in our idle GCP dev account. Here's the three-part fix.

When bcrypt 4.0 removed __about__.__version__, passlib's CryptContext started failing our password hashing at runtime. Why we deleted the abstraction and called bcrypt directly.
Engineering
Heavy module-level SDK imports (boto3, numpy, azure, google.cloud) blew past Cloud Run's 60-second cold-start budget and got our Celery worker SIGTERM'd. The lazy-import fix - and the test patches it broke.
Engineering
A test suite that passed, then failed, then passed - because OneDrive kept syncing node_modules mid-import. How to tell environmental flakes from real bugs, and the vitest flags that fixed it.
Engineering
A stray .title() call turned core_sla into "Core Sla" and quietly 400'd our highest-margin upgrade. Why identifiers and display strings are different species - and stay lowercase end-to-end.
Engineering
Two bugs, one villain - assuming order and shape don't matter. FastAPI matching /rules/{id} before /rules/available, and a frontend helper that already unwrapped the response envelope.
Engineering
One line - sys.modules['boto3'] = MagicMock() - at module level poisoned 3,000 tests across the whole pytest session. Why order-dependent failures are haunted, not flaky.
Engineering
Azure's Support API won't let you file any ticket - including an SLA refund claim - without a paid support plan. Why some "bugs" are policies, and how to detect the entitlement gate early.
Engineering
A query that worked on PostgreSQL detonated on SQLite with 'str' object has no attribute 'hex'. Why the strict test database did us a favor, and converting types at the boundary.
