Phase G0 Day 2 ships storaged: aws-sdk-go-v2 wrapper + chi routes
binding 127.0.0.1:3211 with 256 MiB MaxBytesReader, Content-Length
up-front 413, and a 4-slot non-blocking semaphore returning 503 +
Retry-After:5 when full. Acceptance smoke (6/6 probes) PASSES against
the dedicated MinIO bucket lakehouse-go-primary, isolated from the
Rust system's lakehouse bucket during coexistence.
Cross-lineage scrum on the shipped code:
- Opus 4.7 (opencode): 1 BLOCK + 3 WARN + 3 INFO
- Qwen3-coder (openrouter): 2 BLOCK + 1 WARN + 1 INFO (3 false positives)
- Kimi K2-0905 (openrouter, after route-shopping past opencode's 4k
cap and the direct adapter's empty-content reasoning bug):
1 BLOCK + 2 WARN + 1 INFO
Fixed:
C1 buildRegistry ctx cancel footgun → context.Background()
(Opus + Kimi convergent; future credential refresh chains)
C2 MaxBytesReader unwrap through manager.Uploader multipart
goroutines → Content-Length up-front 413 + string-suffix fallback
(Opus + Kimi convergent; latent 500-instead-of-413 in 5-256 MiB range)
C3 Bucket.List unbounded accumulation → MaxListResults=10_000 cap
(Opus + Kimi convergent; OOM guard)
S1 PUT response Content-Type: application/json (Opus single-reviewer)
Strict validateKey policy (J approved): rejects empty, >1024B, NUL,
leading "/", ".." path components, CR/LF/tab control characters.
DELETE exposed at HTTP layer (J approved option A) for symmetry +
smoke ergonomics.
Build clean, vet clean, all unit tests pass, smoke 6/6 PASS after
every fix round. go.mod 1.23 → 1.24 (required by aws-sdk-go-v2).
Process finding worth recording: opencode caps non-streaming Kimi at
max_tokens=4096; the direct kimi.com adapter consumed 8192 tokens of
reasoning but surfaced empty content; openrouter/moonshotai/kimi-k2-0905
delivered structured output in ~33s. Future Kimi scrums should default
to that route.

Second-pass review via opencode/kimi-k2.6 (different lineage than
Opus 4.7 used in the first pass) caught 2 BLOCKs that Opus missed —
and that the Opus-pass fixes themselves introduced:
- K1: D0.6 used `go install pkg@latest` to verify cgo, but that
command requires a main package; duckdb-go/v2 is a library, so
the verification fails BEFORE exercising cgo and could pass on a
broken-cgo box. Replaced with a real compile-and-run smoke
(tmp module + 5-line main.go that imports + calls sql.Open).
- K2: Gateway stubbed /v1/ingest and /v1/sql in D1.10, but ingestd
serves /ingest and queryd serves /sql. httputil.NewSingleHostReverseProxy
preserves the inbound path by default — D6.1 now specifies a
custom Director that strips the /v1 prefix before forwarding.
Demonstrates the cross-lineage rotation value: one model's review
of the original ≠ different model's review of the post-fix version.
Same dynamic the Rust auditor exploits with Kimi/Haiku/Opus.
Disposition table appended below the Opus pass for full audit trail.
