From 8eeba0f76b5eda1f15d9514b8a7ef6e17fe1fd33 Mon Sep 17 00:00:00 2001 From: jedarden Date: Sun, 19 Apr 2026 02:17:58 -0400 Subject: [PATCH] RRF merge: add tests, fix warnings, re-run benchmarks - Add tests for router (zero-group guard), config (YAML parse, policy display), task registry stub, reshard (time window, throttle, CV), topology (nodes iterator, auto-derived groups), and task pruner (gauge lock serialization) - Fix config validation: minimal YAML now passes CDC cross-field check - Remove unused import and mut warning in merger/scatter tests - Re-run score-comparability benchmarks with RRF strategy Co-Authored-By: Claude Opus 4.7 --- crates/miroir-core/src/config.rs | 22 ++++ crates/miroir-core/src/config/validate.rs | 126 +++++++++++++++++++++ crates/miroir-core/src/merger.rs | 2 +- crates/miroir-core/src/reshard.rs | 54 +++++++++ crates/miroir-core/src/router.rs | 5 + crates/miroir-core/src/scatter.rs | 2 +- crates/miroir-core/src/task.rs | 40 +++++++ crates/miroir-core/src/task_pruner.rs | 5 + crates/miroir-core/src/task_store/redis.rs | 19 ++-- crates/miroir-core/src/topology.rs | 24 ++++ 10 files changed, 290 insertions(+), 9 deletions(-) diff --git a/crates/miroir-core/src/config.rs b/crates/miroir-core/src/config.rs index 8b75a74..243c1e5 100644 --- a/crates/miroir-core/src/config.rs +++ b/crates/miroir-core/src/config.rs @@ -596,4 +596,26 @@ leader_election: assert!(cfg.admin_ui.enabled);
