From cd228839a4f3f05f2d4344c4f98606a90d914984 Mon Sep 17 00:00:00 2001 From: Rick Hightower Date: Fri, 6 Feb 2026 17:52:15 -0600 Subject: [PATCH 1/2] feat: implement lifecycle pruning for BM25 and Vector indexes - Add BM25 prune jobs with SearchIndexer::prune_and_commit callback - Add Vector prune jobs with VectorIndexPipeline::prune_level callback - Wire prune jobs at daemon startup via register_prune_jobs() - Add registry metadata tracking for job telemetry - Extend proto with GetRankingStatusResponse lifecycle fields - Add env.sh and Taskfile.yml for macOS C++ toolchain workaround - Fix flaky scheduler timeout test (use 5s cron interval) - Add memory-retrieval crate with classifier and executor - Add phase 16/17 planning docs for ranking enhancements Co-Authored-By: Claude Opus
