GOLAKE-100. First run writes tests/proof/baseline.json; subsequent
runs diff against it. >10% regression emits a SKIP with REGRESSION
detail (not a fail — perf claim is required:false in claims.yaml so
the gate stays green; the human summary tells the regression story
honestly). Skip-with-loud-reason if any earlier case in the run
failed, per spec "performance only after contract+integration pass."
Workload (deterministic, repeatable):
ingest 1000-row CSV (5 roles × 5 cities × seeded scores) → /v1/ingest
query SELECT count(*) ×20 against the just-ingested dataset
vector add 200 dim=4 vectors with formulaic content (no Ollama)
search ×20 against the perf index with a fixed query vector
RSS per-service post-workload sample via /proc/<pid>/status
Recorded metrics:
ingest_rows_per_sec, query_p50_ms, query_p95_ms,
vectors_per_sec_add, search_p50_ms, search_p95_ms,
rss_{storaged,catalogd,ingestd,queryd,vectord,embedd,gateway}_mb
baseline.json on this box (committed):
25000 rows/sec ingest · 17ms p50 / 24ms p95 query
6250 vectors/sec add · 8ms p50 / 20ms p95 search
queryd 69 MiB · vectord 14 MiB · others 11-29 MiB
Honest measurement-design finding from the very first compare run:
back-to-back runs surfaced -41% ingest and +29% query p50 — pure
disk-cache + queryd-cold-start noise. Single-sample baselines have
real noise floor ≈40%. Recorded as REGRESSION skips so the human
summary surfaces it, not a code regression. Tightening the threshold
or moving to multi-sample medians is a Phase E recommendation.
Verified end-to-end:
just proof contract — 53 pass · 1 skip · ~4s
just proof integration — 104 pass · 1 skip · ~8s
just proof performance — 110 pass · 3 skip · ~10s
just verify — 9 smokes still green · 29s
All 11 cases (4 contract + 6 integration + 1 performance) deterministic
end-to-end. Phase E (final report against the 9 mandated questions)
is the last piece.

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.
