Caught by the audit rerun: with cache-warm binaries, 04 fires its
first SELECT faster than queryd's 500ms refresh tick — Q1 returned
400 ("table not found") even though 03_ingest had registered the
manifest. Subsequent queries (after the next tick) succeeded.
This is an eventual-consistency wait, not a retry — queryd's
contract is that views appear within one tick of catalogd having the
manifest. Production code does not need changing.
Added to lib/http.sh:
proof_wait_for_sql <budget_sec> <sql>
polls a SQL probe until it returns 200 or budget elapses; emits
no evidence (test setup, not a claim).
Used in 04_query_correctness:
Wait up to 5s for queryd to have the view before running the 5
SQL assertions. Skip-with-loud-reason if the view never appears.
Verified: integration mode back to 104 pass / 0 fail / 1 skip after
fix. The skip is the unchanged GOLAKE-085 informational record.
This is exactly the kind of finding the harness was designed to
surface — the regression existed in the codebase the moment Phase D
shipped, but only fired when the next compare run hit cache-warm
timing. Without the harness, it would have surfaced on a CI run
weeks from now and been hard to bisect.

golangLAKEHOUSE
Go reimplementation of the Lakehouse — a versioned knowledge substrate for staffing analytics + local AI workloads.
Status
Phase G0 complete + G1/G1P/G2 shipped. Six binaries plus a seventh (vectord) and an eighth (embedd) on top, fronted by a single gateway. Acceptance smokes green for D1-D6 + G1 + G1P + G2.
End-to-end staffing co-pilot pipeline functional through the gateway:
text → /v1/embed → /v1/vectors/index/<name>/add
text → /v1/embed → /v1/vectors/index/<name>/search → top-K hits
Plus the SQL path:
CSV → /v1/ingest (parses, writes Parquet via storaged, registers
manifest with catalogd)
SQL → /v1/sql (DuckDB over the registered Parquets via httpfs)
See docs/PHASE_G0_KICKOFF.md for the day-by-day record (D1-D6 +
real-scale validation + G1/G1P/G2 pointer at the bottom).
Service inventory
| Bin | Port | Role |
|---|---|---|
gateway |
3110 | Reverse proxy fronting all backing services |
storaged |
3211 | Object I/O over S3 (MinIO in dev) |
catalogd |
3212 | Parquet manifest registry, ADR-020 idempotency |
ingestd |
3213 | CSV → Parquet → register loop |
queryd |
3214 | DuckDB SELECT over registered Parquets via httpfs |
vectord |
3215 | HNSW vector search (+ optional persistence to storaged) |
embedd |
3216 | Text → vector via Ollama (default nomic-embed-text 768-d) |
Acceptance smokes
scripts/d1_smoke.sh # 5-binary skeleton + chi /health + gateway proxy probes
scripts/d2_smoke.sh # storaged GET/PUT/LIST/DELETE + 256 MiB cap + concurrency cap
scripts/d3_smoke.sh # catalogd register/manifest/list + rehydrate-across-restart
scripts/d4_smoke.sh # ingestd CSV → Parquet round-trip + schema-drift 409
scripts/d5_smoke.sh # queryd DuckDB SELECT through httpfs over MinIO
scripts/d6_smoke.sh # full ingest → query through gateway only
scripts/g1_smoke.sh # vectord HNSW recall + dim mismatch + duplicate-create 409
scripts/g1p_smoke.sh # vectord state survives kill+restart via storaged
scripts/g2_smoke.sh # embed → vectord add → search round-trip
Or run the full gate via the task runner (see below):
just verify # vet + tests + 9 smokes; ~33s wall
Task runner
just # show available recipes
just verify # full Sprint 0 gate (vet + tests + 9 smokes)
just smoke <day> # single smoke (d1..d6, g1, g1p, g2)
just doctor # check cold-start deps; --json for CI
just install-hooks # install pre-push hook that runs just verify
After a fresh clone, run just install-hooks once so git push is
gated on the same green chain that ran here. Hook lives in
.git/hooks/pre-push (not tracked; recreated by the recipe).
Cold-start dependencies
- Go 1.25+ at
/usr/local/go/bin(arrow-go pulled the 1.25 floor) gcc+libc-devfor the DuckDB cgo binding (ADR-001 §1.1)justtask runner (apt install juston Debian 13+)- MinIO running on
:9000with bucketlakehouse-go-primary - Ollama running on
:11434withnomic-embed-textloaded (G2) /etc/lakehouse/secrets-go.tomlwith[s3.primary]credentials (storaged + queryd both read this)
just doctor probes all of the above and reports the fix command
for each missing dep. CI / scripts can use just doctor --json.

Predecessor
The Rust Lakehouse this rewrite supersedes lives at
git.agentview.dev/profit/lakehouse. It remains the live system
serving devop.live/lakehouse/ until this Go implementation reaches
feature parity per docs/SPEC.md §7. Then Rust enters
maintenance-only mode.
