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.

Per docs/TEST_PROOF_SCOPE.md, building the claims-verification tier
above the smoke chain. This commit lays the scaffolding and proves
the orchestrator end-to-end with one canary case (00_health).
What landed:
tests/proof/
README.md how to read a report, layout, modes
claims.yaml 24 claims enumerated (GOLAKE-001..100)
run_proof.sh orchestrator with --mode {contract|integration|performance}
and --no-bootstrap / --regenerate-{rankings,baseline}
lib/
env.sh service URLs, report dir, mode, git context
http.sh curl wrappers writing per-probe JSON + body + headers
assert.sh proof_assert_{eq,ne,contains,lt,gt,status,json_eq} +
proof_skip — each emits one JSONL record per call
metrics.sh start/stop timers, value capture, RSS sampling,
percentile compute (for Phase D)
cases/
00_health.sh canary — gateway + 6 services /health → 200,
body identifies service, latency < 500ms (21 assertions)
fixtures/
csv/workers.csv spec's 5-row deterministic CSV
text/docs.txt 4 deterministic vector docs
expected/queries.json expected results for the 5 SQL assertions
Wired into the task runner:
just proof contract # canary only this commit
just proof integration # Phase C
just proof performance # Phase D
.gitignore: /tests/proof/reports/* with !.gitkeep — same pattern as
reports/scrum/_evidence/. Per-run output is a runtime artifact.
Specs landed alongside (J's drops):
docs/TEST_PROOF_SCOPE.md the harness contract this implements
docs/CLAUDE_REFACTOR_GUARDRAILS.md process discipline this harness obeys
Verified end-to-end (cached binaries):
just proof contract wall < 2s, 21 pass / 0 fail / 0 skip
just verify wall 31s, vet + test + 9 smokes still green
Two bugs fixed during canary run, both in run_proof.sh aggregation:
- grep -c exits 1 on zero matches; the `|| echo 0` form concatenated
"0\n0" and broke jq --argjson + integer comparison. Fixed via a
_count helper that captures count-or-zero cleanly.
- per-case table iterated case scripts (filename-based) but cases
write evidence under CASE_ID. Switched to JSONL-file iteration so
multi-case scripts work and the mapping is faithful.
Phase B (contract cases) lands next: 05_embedding, 06_vector_add,
08_gateway_contracts, 09_failure_modes. Each sourcing the same lib
helpers and writing to the same report shape.

Sprint 0 / R-004 / GATE-0.4 — the 9-smoke chain is no longer
documentation only. One command (`just verify`) runs vet + tests +
all 9 smokes; pre-push hook calls it; a regression cannot leave
this machine without explicit --no-verify override.
Recipes:
just verify full gate (33s wall on this box)
just smoke <day> single smoke (d1..d6, g1, g1p, g2)
just smoke-all all 9 smokes only
just doctor dep probe with structured output
(--json for CI / pre-push)
just install-hooks install .git/hooks/pre-push
just fmt|vet|test|build|clean
scripts/doctor.sh probes Go ≥1.25, gcc, MinIO at :9000 with bucket
lakehouse-go-primary, Ollama at :11434 with nomic-embed-text loaded,
/etc/lakehouse/secrets-go.toml with [s3.primary]. Each missing dep
prints its install fix command. JSON mode emits the same shape for
CI / pre-push consumers.
README updated with the task-runner section + just install-hooks
on cold-start. Hooks live in .git/hooks/ (untracked); install
recipe recreates them on a fresh clone.
PATH note: justfile prepends /usr/local/go/bin so recipes find Go
without depending on the parent shell's PATH (ADR-001 §1.x lives
go there).
Verified: just verify exits 0 in 33s wall (vet ~0.1s + test ~0.1s +
9 smokes deterministic per audit baseline). Pre-push hook installed
and bash -n clean.
Closes audit risk R-004 (smokes not gated).
