From 1fa8349e483a24a523d8bfafb6b026ab3a1cc4e9 Mon Sep 17 00:00:00 2001 From: xiaowei Date: Sun, 31 May 2026 11:46:59 +0800 Subject: [PATCH] fix: mode propagation, eps=0.1, BGE connectivity check, vector storage, WriteTimeout 60s Key fixes: - Go task mode now correctly propagates to Rust sidecar via IPC (RunWithMode) - DBSCAN eps lowered from 1.5 to 0.1 (cosine threshold 0.995) - Add BGE HTTP connectivity check (TcpStream 2s timeout) before Step 4 quality backtrace - Fix LanceDB insert_batch: use Float32Array::from_iter_values + try_new with None validity - Fix embed.rs: add .timeout(10s) on encode request - Fix consolidation_pipe.go: nil guards on report - Fix main.go: WriteTimeout 60s (was 10s, causing exit 52 on full mode) - Add vector zero detection + debug logging (norms, sample distances) - Log warning when BGE HTTP unreachable (skip quality backtrace instead of hanging) --- go/cmd/zhiyid/main.go | 6 +- go/internal/api/routes/consolidation_pipe.go | 21 +- go/internal/api/server.go | 51 +++-- go/internal/consolidate/client.go | 43 ++-- rust/src/embed.rs | 1 + rust/src/lancedb_ops.rs | 7 +- rust/src/main.rs | 208 ++++++++++++------- 7 files changed, 211 insertions(+), 126 deletions(-) diff --git a/go/cmd/zhiyid/main.go b/go/cmd/zhiyid/main.go index 1b7015a..8feffc5 100644 --- a/go/cmd/zhiyid/main.go +++ b/go/cmd/zhiyid/main.go @@ -22,9 +22,9 @@ func main() { srv := &http.Server{ Addr: "0.0.0.0:" + port, Handler: api.NewServer(), -
