Cross-lineage review consolidation (3 model passes + 1 runtime pass): - Opus 4.7: 9 findings · 7 fixed inline · 2 deferred - Kimi K2.6: 2 BLOCKs (introduced by Opus fixes) · 2 fixed - Qwen3-coder:480b: 2 WARNs · 1 fixed (D2.4 256 MiB cap + 4-slot semaphore on PUTs) · 1 deferred (Q2 view refresh batching) - Runtime smoke: 1 finding (port 3100 collision with live Rust lakehouse) · fixed (Go dev ports shifted to 3110+) - Total: 14 findings · 11 fixed · 3 deferred to G2 What landed in code: - internal/shared/server.go — chi factory, slog JSON, /health, graceful shutdown via signal.NotifyContext - internal/shared/config.go — TOML loader, DefaultConfig, -config flag - cmd/{gateway,storaged,catalogd,ingestd,queryd}/main.go — five binaries, each ~30 lines using the shared factory - lakehouse.toml — G0 dev defaults (3110-3214) - scripts/d1_smoke.sh — repeatable smoke that exits 0 on PASS - go.mod / go.sum — chi v5.2.5, pelletier/go-toml/v2 v2.3.0 Verified end-to-end via scripts/d1_smoke.sh: - All 5 /health endpoints return 200 with correct service name - Gateway /v1/ingest + /v1/sql stubs return 501 with X-Lakehouse-Stub - Graceful shutdown logs cleanly on SIGTERM - DuckDB cgo path verified separately (sql.Open("duckdb","") + ping) D1 ACCEPTANCE GATE: PASSED.
