G0 D1 ships: skeleton + chi + /health × 5 binaries · acceptance gate PASSED
Phase G0 Day 1 executed end-to-end after a third-pass review by
qwen3-coder:480b consolidated all findings across Opus/Kimi/Qwen
lineages.
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.
Next: D2 — storaged S3 GET/PUT/LIST against MinIO.
