Adapts docs/SCRUM.md framework (originally written for the
matrix-agent-validated repo) to the Go rewrite. Five deliverables:
golang-lakehouse-scrum-test.md top-line + scoring + verdict
risk-register.md 12 findings, R-001..R-012
claim-coverage-table.md claim/test/risk for Sprint 2
sprint-backlog.md 5 sprints, ~2 weeks of work
acceptance-gates.md DoD as runnable commands
Every claim cites file:line, command output, or "missing evidence."
Smoke chain ran clean (33s wall, all 9 PASS) and is captured in
reports/scrum/_evidence/smoke_chain.log (gitignored — runtime artifact).
Scoring:
Reproducibility 7/10 9 smokes deterministic, no just/CI gate
Test Coverage 6/10 internal/ packages tested, 6/7 cmd/ aren't
Trust Boundary 7/10 escapes ok, zero auth, /sql is RCE-eq off-loopback
Memory Correctness 3/10 pathway/playbook/observer not yet ported
Deployment Readiness 4/10 no REPLICATION, no env template, no systemd
Maintainability 8/10 no god-files, 7 lean binaries, ADRs current
Top three risks:
R-001 HIGH queryd /sql + DuckDB + non-loopback bind = RCE-equivalent
R-002 HIGH internal/shared (server.go + config.go) zero tests
R-003 HIGH internal/storeclient zero tests, used by 2 services
R-004 MED 9-smoke chain green but not gated (no justfile/hook)
The audit is the work; refactors come after. Sprint 0 owns coverage
+ CI gating; Sprint 1 owns trust-boundary decisions; Sprints 2-3 are
mostly design-bar work for unbuilt agent components.
.gitignore exception: /reports/* + !/reports/scrum/ keeps reports/
a runtime-artifact directory while exposing reports/scrum/ as
tracked documentation. Mirrors the pattern future audit passes will
land in.

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.

Two documents only — no Go code yet. PRD restates the problem and
preserves the Rust PRD's invariants verbatim, then maps the locked
stack to Go libraries and surfaces four hard problems (DuckDB-via-cgo
for the query engine, Lance dropped, Dioxus → HTMX, arrow-go maturity).
SPEC walks each Rust crate + TS surface and tags the port with library
choice / effort estimate / risk + a 5-phase migration plan from
skeleton (Phase G0) to demo parity (Phase G5).
Six open questions remain that gate Phase G0:
- DuckDB cgo OK?
- HTMX vs React for the UI?
- Repo location?
- Distillation v1.0.0 port verbatim or rebuild?
- Pathway memory data — port 88 traces or start clean?
- Auditor lineage — port audit_baselines.jsonl or restart?
