This meant k8s Resource nodes and kustomize Module nodes were never created or updated during incremental re-indexing — only after a fresh full index. Add the pass after the semantic pass, following the same timing-log pattern as the other incremental passes. Pass changed_files (not the full file list) so only modified/added YAML files are re-processed. Add two regression tests: - incremental_k8s_manifest_indexed: full index + add manifest via incremental, verifies Resource node appears in the DB - incremental_kustomize_module_indexed: same for kustomization.yaml Module node Co-Authored-By: Claude Sonnet 4.6 --- src/pipeline/pipeline_incremental.c | 4 + tests/test_pipeline.c | 137 ++++++++++++++++++++++++++++ 2 files changed, 141 insertions(+) diff --git a/src/pipeline/pipeline_incremental.c b/src/pipeline/pipeline_incremental.c index 78e2ffde6..85443bec4 100644 --- a/src/pipeline/pipeline_incremental.c +++ b/src/pipeline/pipeline_incremental.c @@ -265,6 +265,10 @@ int cbm_pipeline_run_incremental(cbm_pipeline_t *p, const char *db_path, cbm_fil cbm_log_info("pass.timing", "pass", "incr_semantic", "elapsed_ms", itoa_buf((int)elapsed_ms(t)));

The pass existed only in the sequential fallback path, so any repo large enough to trigger parallel indexing produced zero k8s Resource and kustomize Module nodes. Discovered via live testing against a 954-file gitops repo: the parallel path was taken, k8s pass was silently skipped, and search_graph returned 0 Resource nodes despite 213 kustomize overlays and hundreds of manifests. Add the pass after cbm_parallel_resolve() in the parallel branch, matching the same pattern (fail-open, cancel check, timing log) as the sequential path.
