From c4c4a974184aa721df0d945b1f612fabf68f9776 Mon Sep 17 00:00:00 2001 From: Dmitry Teryaev Date: Mon, 22 Jun 2026 09:30:31 +0300 Subject: [PATCH 1/2] perf(vectors): lifespan-cached LayeredIgnore + is_ignored memo (PR-P3) - Define IGNORE ContextKey (version-detected) alongside PROJECT_ROOT/EMBEDDER/LANCE_DB - Provide IGNORE once per flow run in coco_lifespan (LayeredIgnore constructed once) - Convert process_java_file, process_sql_file, process_yaml_file to use IGNORE ContextKey - Add _mega_cache to LayeredIgnore, memoizing _mega(rel) by directory - Add test_is_ignored_mega_caches_by_directory and test_layered_ignore_memo_preserves_decisions - Add test_layered_ignore_provided_once_per_flow (HEAVY) in test_lancedb_e2e.py Scope: Only the three process_*_file sites converted. Sites :182 and :578 (_approximate_vectors_total and app_main pre-walk) left untouched as they call cocoindex_excluded_patterns() once per run, not per-file.
