root 6af0520ed2 A: fail-loud on non-loopback bind — closes worst case of R-001
shared.Run now refuses to bind a non-loopback address unless the
LH_<SERVICE>_ALLOW_NONLOOPBACK=1 env is set. Single change covers
all 7 binaries via the existing Run call site; no per-binary
wiring needed.

Closes the accidental-0.0.0.0 deploy attack surface for R-001:
queryd /sql is RCE-equivalent off loopback (DuckDB has filesystem
read + COPY TO + read_text), but the gate applies to every binary
uniformly so the same posture covers vectord (mutation routes),
catalogd (manifest writes), and the others.

What passes the gate:
  127.0.0.1:port, 127.x.y.z:port (full /8), [::1]:port,
  localhost:port, OR explicit env LH_<SVC>_ALLOW_NONLOOPBACK=1

What fail-louds:
  0.0.0.0:port, [::]:port, :port (all interfaces),
  any non-loopback IP, any non-localhost hostname,
  unparseable shapes ("", "no port", garbage)

Override env is strict equality "1" — typos like "true"/"yes" do NOT
trigger it, so a future operator can't accidentally expose by typing
the wrong value. Override fires log a structured warn so the choice
is auditable in production.

Error message cites the env name AND R-001 by name so operators see
the fix path without grepping:
  "refusing non-loopback bind \"0.0.0.0:3214\" for \"queryd\"
   (set LH_QUERYD_ALLOW_NONLOOPBACK=1 to override; see audit R-001)"

internal/shared/bind.go            — requireLoopbackOrOverride + isLoopbackAddr
internal/shared/bind_test.go       — 7 test funcs incl. table-driven
                                     IPv4/IPv6/hostname coverage and
                                     per-service env isolation
internal/shared/server.go          — 1-line gate in Run before listen

Verified:
  go test -short ./internal/shared/ — all green (was 14 funcs, now 21)
  just verify                       — vet + test + 9 smokes still 33s

Doesn't address R-001's full attack surface (any reachable port can
issue arbitrary SQL); ADR-003 + Bearer-token middleware is the
follow-up. This commit makes the implicit "localhost-only is the auth
layer" guarantee explicit and un-bypassable without explicit env.

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-dev for the DuckDB cgo binding (ADR-001 §1.1)
  • just task runner (apt install just on Debian 13+)
  • MinIO running on :9000 with bucket lakehouse-go-primary
  • Ollama running on :11434 with nomic-embed-text loaded (G2)
  • /etc/lakehouse/secrets-go.toml with [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.

Layout

docs/                         Direction + spec + ADRs + day-by-day
cmd/                          One main package per binary
internal/                     Shared packages — storeclient, catalogclient,
                                secrets, shared, embed, gateway, plus
                                per-service implementation packages
scripts/                      Smokes + ancillary tooling

Reading order

  1. docs/PRD.md — what we're building and why
  2. docs/SPEC.md — how, per-component
  3. docs/DECISIONS.md — ADRs (ADR-001 foundational)
  4. docs/PHASE_G0_KICKOFF.md — day-by-day from D1 through G2
  5. docs/RUST_PATHWAY_MEMORY_NOTE.md — historical reference for the Rust era's pathway memory (not migrated, by ADR-001 #5)

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.
