## TL;DR

The wrapper likely loads the whole history or report into memory. Bound the commit range, stream the scanner output, and process findings incrementally instead of buffering.

## Error

```text
agent's gitleaks wrapper broke with error on a repo with 100k commits
```

## Steps

1. Reproduce with a bounded range to confirm scale is the trigger. Expected: small ranges work, huge ones break.
2. Limit the commit walk with log options (recent history first, then backfill). Expected: bounded work per run.
3. Stream the scanner's JSON output line by line instead of loading it whole. Expected: constant memory.
4. Process and persist findings incrementally. Expected: progress survives crashes.
5. Backfill older history in background chunks. Expected: full coverage over time.

## When to use

- Wrapper crashes or hangs on very large histories.
- Building scan agents for big repos.

## When not to use

- Config or rule errors (fix those first).
- Small repos breaking (different bug).

## Tool compatibility

- Gitleaks; git log options; streaming JSON parsers.

## Variant phrasings

### gitleaks wrapper out of memory

Stream it.

### scan breaks on 100k commits

Bound the range.

## Why it happens

Wrappers written for small repos buffer everything; hundred-thousand-commit histories exceed memory and time budgets.

## Edge cases

- Merge-heavy histories walk slower; bound by time as well as count.
- Report schema changes can break parsers; pin the scanner version.
- Partial results must be marked partial until backfill completes.
