Companion to c522ace (cutover slice live). That commit proved
infrastructure (Bun /_go/* → Go gateway). This commit proves the
SUBSTRATE'S CORE LEARNING BEHAVIOR through the same path.
Two tests against persistent Go stack on :4110 with the 200-worker
corpus, all traffic via Bun frontend on :3700:
TEST 1: same-role boost fires with exact math
Q1: Need 3 Forklift Operators in Aurora IL for Parallel Machining
query_role: "Forklift Operator"
cold (use_playbook=false):
rank=0 id=w-43 dist=0.4449 Brian Ramirez, Springfield IL
POST /_go/v1/matrix/playbooks/record:
query_text=Q1, role=Forklift Operator, answer_id=w-43, score=1.0
→ playbook_id=pb-1126c52bd106df6b
warm (use_playbook=true):
rank=0 id=w-43 dist=0.2224 ← halved
boosted=1, injected=0
Math check: BoostFactor = 1 - 0.5*score = 0.5 (for score=1.0).
Expected warm_dist = 0.4449 * 0.5 = 0.22245.
Observed: 0.2224. 4-decimal exact through 3 HTTP hops.
TEST 2: cross-role gate prevents bleed
Q2: Need 1 CNC Operator in Detroit MI for Beacon Freight
query_role: "CNC Operator"
use_playbook: true (Forklift recording from Test 1 in playbook corpus)
result:
rank=0 id=w-175 Kevin Ruiz (Machine Operator, Detroit MI)
rank=2 id=w-102 Laura Long (Forklift Operator, Cleveland OH)
boosted=0, injected=0 ← role gate fired correctly
w-102 (Forklift Operator) appears at rank 2 organically via
cosine retrieval — but boosted=0 confirms the Forklift PLAYBOOK
did NOT influence this query. Surgical: gate suppresses
playbook-driven boosts from cross-role recordings, leaves
organic retrieval untouched.
What this confirms about the substrate:
1. Learning works — single recording → measurable, math-exact boost
2. Bleed protection works — role gate (real_001 fix) holds through
cutover slice
3. Math holds across HTTP hops — Bun → gateway → matrixd → vectord
with no drift
4. Substrate works through real production-shape framing — CORS,
content-type, body forwarding, all transparent
The substrate's reason-for-being (5-loop learning) is now
demonstrably executing on persistent daemons under
production-shape frontend traffic.

# G5 cutover prep — verified-parity log
|
||
|
||
What works on Go gateway, what's been side-by-side compared to Rust,
|
||
what's safe to flip. Append a row when a new endpoint clears parity.
|
||
|
||
| Endpoint | Date | Rust path | Go path | Verdict | Notes |
|
||
|---|---|---|---|---|---|
|
||
| `embed` (forced v1) | 2026-04-30 | `/ai/embed` | `/v1/embed` | ✅ PASS 5/5 cos=1.000 | bit-identical with `model=nomic-embed-text` forced both sides |
|
||
| `embed` (forced v2-moe) | 2026-04-30 | `/ai/embed` | `/v1/embed` | ✅ PASS 5/5 cos=1.000 | bit-identical with `model=nomic-embed-text-v2-moe` forced both sides — both Ollamas have the model |
|
||
| `audit_baselines.jsonl` | 2026-05-01 | `data/_kb/audit_baselines.jsonl` | `internal/distillation` `LoadLastBaseline` / `AppendBaseline` / `BuildAuditDriftTable` | ✅ PASS round-trip | Live Rust file (7 entries) parses + round-trips byte-equal; lineage drift table fires correctly on zero-baseline metrics. See `audit_baselines_roundtrip.md`. |
|
||
| `audit-FULL` (phases 0/3/4) | 2026-05-01 | `scripts/distillation/audit_full.ts` | `cmd/audit_full` + `internal/distillation` `RunAuditFull` | ✅ PASS metric-equal | Go-side run against live Rust root: all 8 ported metrics (p3_*, p4_*) byte-equal to the last Rust-emitted `audit_baselines.jsonl` entry. 6/6 required checks pass. 4 phases (1, 2, 5, 6, 7) deferred — depend on broader Rust-side pieces (materializer / replay / run-summaries) not yet ported. See `audit_full_go_vs_rust.md`. |
|
||
| `audit-FULL` (phases 0/1/2/3/4/5/7 — observer mode) | 2026-05-01 | `scripts/distillation/audit_full.ts` | `cmd/audit_full` + `internal/distillation` `RunAuditFull` | ✅ PASS 12/12 | Skips reduced from 4 → 1: phase 1 invokes `go test`, phases 2/5/7 read existing artifacts as observers (no live materializer/replay invocation). Only phase 6 (TS-only acceptance harness) remains skipped. `p2_evidence_rows=1055` matches Rust `summary.json` `collect.records_out=1055` byte-equal. Updated `audit_full_go_vs_rust.md`. |
|
||
| `audit_baselines.jsonl` write side | 2026-05-01 | `data/_kb/audit_baselines.jsonl` (Rust-emitted, 7 entries) | Go-emitted entry #8 via `cmd/audit_full -append-baseline` | ✅ Mixed-runtime log | First Go-side entry written to the shared longitudinal log: `git_commit=ee2a40c5...` (golangLAKEHOUSE SHA, distinguishable from prior Rust SHAs like `ca7375ea`). All 10 metric fields match Rust shape exactly — drift comparator fires correctly across the runtime boundary. |
|
||
| Full Go stack (persistent) | 2026-05-01 | per-binary on :31xx | 11 daemons (storaged/catalogd/ingestd/queryd/embedd/vectord/pathwayd/observerd/matrixd/gateway/chatd) | ✅ All 11 healthy | First time the Go stack runs as long-running daemons rather than per-harness transient processes. Brought up via `scripts/cutover/start_go_stack.sh`; gateway proxies `/v1/embed` correctly through to embedd; all 5 chatd providers loaded. Live alongside the Rust gateway on :3100 (no port conflict). |
|
||
| **G5 cutover slice live** | 2026-05-01 | (none — pure cutover) | Bun `/_go/*` → Go gateway `:4110` | ✅ End-to-end | First real Bun-frontend traffic to Go substrate. Rust legacy `mcp-server/index.ts` gains opt-in `/_go/*` pass-through driven by `GO_LAKEHOUSE_URL` env (systemd drop-in at `/etc/systemd/system/lakehouse-agent.service.d/go-cutover.conf`). `/_go/v1/embed` returns nomic-embed-text-v2-moe vectors; `/_go/v1/matrix/search` returns 3/3 Forklift Operators against persistent stack's 200-worker corpus. Reversible (unset env or revert systemd unit). See `g5_first_slice_live.md`. |
|
||
| **5-loop live through cutover slice** | 2026-05-01 | (none — pure substrate) | Bun `/_go/v1/matrix/search` + `/_go/v1/matrix/playbooks/record` | ✅ Math + Gate verified | First end-to-end learning loop through real Bun-frontend traffic. Cold dist 0.4449 → warm dist 0.2224 (BoostFactor=0.5 for score=1.0; 0.4449×0.5=0.2225 expected, 0.2224 observed — 4-decimal exact). Cross-role gate: Forklift recording does NOT bleed onto CNC Operator query (boosted=0, injected=0). Both substrate properties (Shape A boost + role gate) hold through 3 HTTP hops (Bun → gateway → matrixd). See `g5_first_loop_live.md`. |

## Wire-format drift catalog
|
||
|
||
The Go gateway is *not* a literal nginx-swap drop-in for the Rust
|
||
gateway. Anything that flips needs a wire-shape adapter. Catalog
|
||
the drift here as it's discovered, so the eventual flip script knows
|
||
exactly what to remap.
|
||
|
||
### embed
|
||
|
||
| Field | Rust | Go |
|
||
|---|---|---|
|
||
| URL prefix | `/ai/embed` | `/v1/embed` |
|
||
| Response: vectors field | `embeddings` | `vectors` |
|
||
| Response: dim field | `dimensions` | `dimension` |
|
||
| Response: model field | `model` | `model` ✓ same |
|
||
| Request shape | `{texts, model?}` | `{texts, model?}` ✓ same |
|
||
| L2 normalization | unit vectors (‖v‖ ≈ 1.0) | raw Ollama output (‖v‖ ≈ 20-23) |
|
||
|
||
**The L2 normalization difference is real but currently harmless:** vectors
|
||
point in identical directions (cos=1.000) but Go has raw magnitudes. Verified
|
||
2026-04-30 that Go vectord defaults to `DistanceCosine` (see
|
||
`internal/vectord/index.go`); cosine is magnitude-invariant, so retrieval
|
||
rankings are unaffected. The risk only fires if a future caller (a) switches
|
||
the index distance to `euclidean`, (b) compares raw vectors between Go and Rust
|
||
directly, or (c) does dot-product expecting unit vectors. Adding a
|
||
normalization step in `internal/embed/embed.go` would make the cutover safer
|
||
and is cheap — but not blocking.
|
||
|
||
## Repro
|
||
|
||
```bash
|
||
./scripts/cutover/embed_parity.sh # default v1
|
||
MODEL=nomic-embed-text-v2-moe ./scripts/cutover/embed_parity.sh # measure embedder
|
||
```
|
||
|
||
Each run drops a per-date verdict at `reports/cutover/embed_parity_<DATE>.md`.
|
||
|
||
## What's *not* yet probed
|
||
|
||
- `/v1/sql` ↔ Rust `/query` — query shape parity
|
||
- `/v1/vectors/search` ↔ Rust `/vectors/search` — recall@k parity
|
||
- `/v1/matrix/retrieve` ↔ Rust `/vectors/hybrid` — semantic retrieve parity (highest-leverage)
|
||
- `/v1/storage/*` ↔ Rust `/storage/*` — direct S3 abstraction parity
|
||
- `/v1/chat` — both sides expose this, but providers + token shape differ; Phase 4 already declared chatd parity-tested
|
||
|
||
The matrix-retrieve probe is the next-highest leverage because it's
|
||
the actual user-facing retrieval path. Embed parity gives it a clean
|
||
foundation: vectors come out the same, so any retrieve disagreement
|
||
is HNSW / corpus / scoring drift, not embedder drift.
