Adds cmd/fake_ollama, a minimal Ollama-API-compatible fake that
implements just enough surface for embedd to drive end-to-end
without a real Ollama install:
GET /api/tags — fixed model list including nomic-embed-text
POST /api/embeddings — deterministic dim-D vector from sha256(prompt)
GET /health — for the smoke's poll_health helper
Same prompt → bit-identical vector across runs, machines, and CI
nodes. Vectors are NOT semantically meaningful; the fake validates
the embed CONTRACT (dimension echo, response shape, status codes,
deterministic round-trip), not real semantic ranking. Real ranking
still requires real Ollama and lives in scripts/g2_smoke.sh + the
integration tier of the proof harness.
scripts/g2_smoke_fixtures.sh — full chain smoke against the fake:
- Build fake_ollama + embedd + vectord + gateway
- Start fake on :11435 (distinct from real Ollama at :11434)
- Generate temp lakehouse.toml with provider_url override
- Boot embedd/vectord/gateway with --config <override>
- 4 assertions: dim=768, deterministic same-text, different-text
divergence, bad-model → 4xx/5xx (fake 404 → embedd 502)
- Trap-cleanup tears down all 4 binaries + tmp config
Wired into the task runner:
just smoke-g2-fixtures
Closes R-006 partially:
- Embed half: ✓ — CI / fresh-clone reviewers without Ollama can
now run the embed contract smoke
- Storage half: deferred — mocking S3 protocol is non-trivial
(multipart, signed URLs, etc.) and MinIO itself is lightweight
enough to install via Docker in any CI environment. Documented
as Sprint 0 follow-up if a CI system without Docker shows up.
What this DOESN'T cover:
- Real semantic similarity (use scripts/g2_smoke.sh + real Ollama)
- Real Ollama API quirks (timeouts, version-specific shapes,
/api/embed batch endpoint that newer versions support)
Verified:
bash scripts/g2_smoke_fixtures.sh — 4/4 assertions PASS, ~3s wall
just verify — vet + test + 9 smokes still green
Doesn't replace the existing g2_smoke.sh (which still requires real
Ollama and exercises the actual embed semantics). Adds an alternate
mode for portability.

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.
