Current state: specification bootstrap only. There is intentionally no Go module or application scaffold yet because the architecture and dependency-injection choices still require approval.

Local dataset input

Place the provided archive at:

data/incoming/challenge_data.csv.gz

The entire data/incoming/ payload is ignored by Git. Future import tooling will read from this location (or an explicitly supplied path), stream the compressed CSV, validate it, and write a tracked import manifest containing the source checksum, schema version, row counts, quality results, and importer revision. The raw file and resulting PostgreSQL data are not committed.

Planned runnable boundaries

One repository may expose several small cmd/ entry points while sharing domain packages under internal/:

HTTP API
dataset importer
database migration command
analytics refresh/background job, only if the approved spec requires one

The exact package layout is deferred until the Go architecture and DI decisions are approved.
