Operational sync exercises often fail quietly. You will build matching routines with tolerances, exception buckets, and human-readable exception exports suitable for email threads.
What you build
- Key selection and normalization strategies
- Tolerance bands with explicit units
- Exception queues with reasons encoded
- Human-readable CSV exports for reviewers
- Unit tests for near-duplicate rows
- Hashing strategies for wide rows
- Change logs for rule tweaks
Outcomes
- Match two sample logs with documented tolerances
- Produce an exception file your instructor can skim in five minutes
- List three ways naive joins create false positives

FAQ
Do we use databases?
SQLite and in-memory joins suffice. Larger engines are optional reading.

No. Patterns are technical; policy decisions stay with your controllers.
What is excluded?
We do not cover distributed stream reconciliation.
