## 2026-07-09 - Avoid N+1 API blocking in SBOM aggregator
**Learning:** The `collect_inventories` function in `scripts/ci/sbom_inventory_aggregator.py` was fetching SBOMs from the GitHub dependency graph synchronously for every repository in the organization. For large organizations (up to 500 repos), this N+1 network/CLI bottleneck significantly stalled the aggregation workflow.
**Action:** Use `concurrent.futures.ThreadPoolExecutor` to fetch SBOMs concurrently when multiple repositories are provided, bounded by a `max_workers` limit (e.g., 10) to avoid overwhelming the CLI/API, while preserving the fast serial path for single-item inputs.

P2 Learning entry names a non-existent label_matches inner function, contradicting the changed code

  • Location: .jules/bolt.md:46
  • Problem: The new learning entry (lines 46-48) states the regex-recompilation anti-pattern was found inside the label_matches inner function of scripts/ci/opencode_review_normalize_output.py. Current-head code defines the inner function as label_starts (focused hunk def label_starts(candidate: str)), and no label_matches symbol appears in the changed files, so the changed documentation contradicts the code it describes; the entry also asserts measurable overhead without any benchmark evidence.
  • Root cause: The learning note was written from an approximate or stale function reference instead of the actual current-head symbol label_starts.
  • Fix: Rename label_matches to label_starts in the Learning: sentence (and either attach the measured-overhead benchmark or soften the claim). Suggested diff below.
  • Regression test: python3 -m pytest tests, plus grep -rn 'label_matches' scripts/ci/opencode_review_normalize_output.py .jules/bolt.md should return no matches after the fix.

**Action:** When performing deep text inspection using repetitive substring or pattern matching across a known set of keys or labels, pre-compile the regex objects at the module level and reuse them to avoid compilation overhead.
