[0xMegie]

Area: apps/s03-indexer/src/**

Goal: Verify indexing resumes from the last processed ledger.

Tasks:

• Simulate a stored checkpoint.
• Assert the indexer starts from the right ledger.
• Assert missing checkpoint starts from configured genesis.

Acceptance:

• Test is deterministic.
• bun run --cwd apps/s03-indexer test passes.

Hi maintainer, I’d like to work on this issue.

I understand the goal is to verify that the indexer resumes from the last processed ledger instead of restarting incorrectly. I’ll focus on the "apps/s03-indexer/src/**" area and add deterministic tests around checkpoint handling.

My approach would be to simulate a stored checkpoint, assert the indexer starts from that ledger, then cover the fallback case where no checkpoint exists and it starts from the configured genesis ledger.

I’ll keep the change focused on the test coverage and make sure "bun run --cwd apps/s03-indexer test" passes before submitting.
