 ## 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.
+## 2026-07-09 - Pre-compile Regex Patterns in Embedded Python Loop-called Functions
+**Learning:** Found a regex recompilation bottleneck in `scripts/ci/opencode_review_approve_gate.sh` where `hunk_header = re.compile(...)` was defined inside the `changed_new_lines` inner Python function. Even when the outer Python execution is embedded in a shell script, recompiling a regex object inside a function called repetitively (like processing git diff lines for multiple files) incurs measurable overhead.
+**Action:** Move inline regex compilation (using `re.compile()`) outside of loop-called functions to the module level, even when the Python script is embedded in a bash file (`cat << 'EOF' | python3`). Ensure global variables/constants are well documented.

 **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.
 ## 2026-07-09 - Pre-compile Regex Patterns in Embedded Python Loop-called Functions
-**Learning:** Found a regex recompilation bottleneck in `scripts/ci/opencode_review_approve_gate.sh` where `hunk_header = re.compile(...)` was defined inside the `changed_new_lines` inner Python function. Even when the outer Python execution is embedded in a shell script, recompiling a regex object inside a function called repetitively (like processing git diff lines for multiple files) incurs measurable overhead.
-**Action:** Move inline regex compilation (using `re.compile()`) outside of loop-called functions to the module level, even when the Python script is embedded in a bash file (`cat << 'EOF' | python3`). Ensure global variables/constants are well documented.
