Foo Bar Metric Definition Backfill

Fix a failed backfill of a new metric definition. The backfill job partially ran, left orphaned data, and the metric table has gaps or duplicates. Recover and complete the backfill idempotently.

I’m going to inspect the repository and find the backfill code, the metric table schema, and any failure/retry logic so I can reproduce the duplicate/missing-data issue before patching it.

I didn’t find the repo root with the first pass, so I’m scanning common workspace locations and looking for the backfill code and database setup directly.

The first run exposed a verification bug in the script, not a load bug: Postgres returned `75.00` and ClickHouse returned `75`. I’m switching verification to compare integer cents and distinct-day counts so reruns validate cleanly even across formatting differences.

We ran a backfill to populate our new metric table, but it failed partway through. Now we have duplicate or missing data.

Can you fix it and make sure the backfill completes correctly?

Starting State
postgres-16clickhouse

Postgres has source events. ClickHouse has analytics.metric_daily with partial/duplicate backfill data. Fix and complete the backfill.

Tasks1
fix-metric-backfillingestion

Repair the metric backfill: remove partial/duplicate data, ensure idempotency, and backfill all historical dates correctly.
