materializer + replay ports + vectord substrate fix verified at scale

Two threads landing together — the doc edits interleave so they ship
in a single commit.

1. **vectord substrate fix verified at original scale** (closes the
   2026-05-01 thread). Re-ran multitier 5min @ conc=50: 132,211
   scenarios at 438/sec, 6/6 classes at 0% failure (was 4/6 pre-fix).
   Throughput dropped 1,115 → 438/sec because previously-broken
   scenarios now do real HNSW Add work — honest cost of correctness.
   The fix (i.vectors side-store + safeGraphAdd recover wrappers +
   smallIndexRebuildThreshold=32 + saveTask coalescing) holds at the
   footprint that originally surfaced the bug.

2. **Materializer port** — internal/materializer + cmd/materializer +
   scripts/materializer_smoke.sh. Ports scripts/distillation/transforms.ts
   (12 transforms) + build_evidence_index.ts (idempotency, day-partition,
   receipt). On-wire JSON shape matches TS so Bun and Go runs are
   interchangeable. 14 tests green.

3. **Replay port** — internal/replay + cmd/replay +
   scripts/replay_smoke.sh. Ports scripts/distillation/replay.ts
   (retrieve → bundle → /v1/chat → validate → log). Closes audit-FULL
   phase 7 live invocation on the Go side. Both runtimes append to the
   same data/_kb/replay_runs.jsonl (schema=replay_run.v1). 14 tests green.

Side effect on internal/distillation/types.go: EvidenceRecord gained
prompt_tokens, completion_tokens, and metadata fields to mirror the TS
shape the materializer transforms produce.

STATE_OF_PLAY refreshed to 2026-05-02; ARCHITECTURE_COMPARISON decisions
tracker moves the materializer + replay items from _open_ to DONE and
adds the substrate-fix scale verification row.

# STATE OF PLAY — Lakehouse-Go
**Last verified:** 2026-04-30 ~16:42 CDT
**Verified by:** live probes + `just verify` PASS + multi-coord stress run #011 (full 9-phase scenario, 67 captured events, 1 Langfuse trace + 111 child observations covering every phase + every external call), not memory.
**Last verified:** 2026-05-02 ~03:00 CDT
**Verified by:** live probes + `just verify` PASS + multitier_100k **full-scale re-run on persistent stack** (132,211 scenarios across 5min @ conc=50, 0 failures across all 6 classes — was 4/6 at 0% pre-fix). Substrate fix (i.vectors side-store + safeGraphAdd + smallIndexRebuildThreshold=32 + saveTask coalescing) holds at original failure-surfacing footprint.
> **Read this FIRST.** When the user says "we're working on lakehouse," default to the Go rewrite (this repo); the Rust legacy at `/home/profit/lakehouse/` is maintenance-only. If memory contradicts this file, this file wins. Update it when something is verified working — not when a phase finishes.

@ -211,6 +213,8 @@ Verbatim verdicts at `reports/scrum/_evidence/2026-04-30/verdicts/`. Disposition
- `temperature` is **omitted** for Anthropic 4.7 (handled by `Request.Temperature *float64`); don't re-add it.
- chatd-smoke runs with **all cloud providers disabled** intentionally so the suite doesn't depend on API keys; that's why it can't catch B-3-class bugs (those need a fake-server fixture, see Sprint 0 follow-up).
- **Langfuse Go-side client lives at `internal/langfuse/`** with best-effort fail-open posture. URL+creds from `/etc/lakehouse/langfuse.env`. Don't propose to "wire Langfuse on Go side" — it's wired; multi_coord_stress is the proof.
- **vectord's source-of-truth is `i.vectors`, NOT the coder/hnsw graph.** The `Index` struct holds a parallel `vectors map[string][]float32` updated on every successful Add/Delete; the graph is a derived, replaceable view. `safeGraphAdd`/`safeGraphDelete` wrap the library's panic-prone ops; `rebuildGraphLocked` reads from `i.vectors` (graph-state-independent). Don't propose to "drop the side map for memory" — it's the load-bearing piece that makes Add panic-recoverable past the small-index threshold (closes the multitier_100k 277884b 96-98% fail). The prior `i.ids` set was folded into `i.vectors` keys.
- **vectord saves are coalesced async, not synchronous.** `cmd/vectord/main.go` runs a per-index `saveTask` that single-flights through `Persistor.Save` — at most one in-flight + one pending. Add returns OK before the save completes; an Add-then-crash can lose ~1 save's worth of data, matching ADR-005's fail-open posture. Don't propose to "make saves synchronous for durability" — that re-introduces the lock-contention bottleneck (1-2.5s tail at conc=50, observed 2026-05-01) without fixing a real durability hole (in-memory state is the source of truth in flight).

Documented as deferred-until-need rather than ignored. |
| (close-bug) | **coder/hnsw v0.6.1 panic — REAL FIX landed** (2026-05-01 ~22:25). The 277884b multitier_100k run hit 96-98% fail on 2/6 scenarios from a v0.6.1 nil-deref (`layerNode.search`) that fires when the graph transitions through degenerate states post-Delete. Initial recover() guard caught panics but returned errors at the same rate. **Real fix**: lift the source-of-truth out of coder/hnsw — `i.vectors map[string][]float32` side store maintained alongside the graph, panic-safe `safeGraphAdd`/`safeGraphDelete` wrappers, `rebuildGraphLocked` reads from `i.vectors` (independent of graph state), warm-path Add falls back to rebuild on panic. Side effect: `i.ids` collapsed into `i.vectors` keys; `Len()` reads from `len(i.vectors)`. Memory cost: ~2x for vectors. Verification: 7 new regression tests in `index_test.go` (`TestAdd_PastThreshold_SustainedReAdd` reproduces the multitier shape — 64-entry index, 800 upserts, 0 errors), `just verify` PASS, multitier_100k re-run on persistent stack 19,622 scenarios / 0 failures across all 6 classes. p50 on previously-failing scenarios went 5ms (instant fail) → 551ms (real Add work — honest cost of correctness). |
| (perf-fix) | **Save coalescing — write-path lock contention closed** (2026-05-01 ~22:50). The panic fix exposed a second bottleneck: every successful Add called `Persistor.Save` synchronously, which takes the index RLock for `Encode` (~6MB JSON for 1942-entry × 768d) — blocking concurrent Add Lock acquisitions. 5min sustained run showed playbook scenario p50 climbing 551ms→1398ms as the index grew. **Fix**: `saveTask` per-index single-flight coalescer in `cmd/vectord/main.go``saveAfter` now triggers an async save; concurrent triggers during an in-flight save mark "pending" so N triggers collapse into ≤2 actual saves. RPO trade: Add returns OK before save completes (~1 save's worth of crash-loss exposure; same fail-open posture as ADR-005). Verification: 3 new tests in `cmd/vectord/main_test.go` (50-trigger pile-up → 2 saves; single → 1; error doesn't stall). Re-run: surge_fill_validate p50 1296ms→**47ms** (~28× faster), playbook_record_replay 1398ms→**385ms** (~3.6× faster), throughput 144→**668 scen/sec** at 0% fail. Restart-rehydrate verified — playbook_memory 4041 entries persisted to MinIO and round-tripped cleanly. |

Re-run: 0 failures across 19,622 scenarios (was 96-98% on 2/6). **DONE.** Architecture invariant in STATE_OF_PLAY "DO NOT RELITIGATE". |
| 2026-05-02 | **Substrate fix verified at original failure scale** | Re-ran multitier 5min @ conc=50 (the footprint that originally surfaced the bug at 96-98% fail). Result: 132,211 scenarios at 438/sec, **6/6 classes at 0% failure**. Throughput dropped 1,115/sec → 438/sec because broken scenarios now do real HNSW Add work. Tails healthy: surge_fill_validate p99=1.53s, playbook_record_replay p99=2.32s. **Fix scales — closing the open thread.** |
| _open_ | Drop Python sidecar from Rust aibridge | Universal-win architectural cleanup. ~200 LOC, removes 1 runtime + 1 process. |
| _open_ | Port Rust materializer to Go (transforms.ts) | Unblocks Go-only end-to-end pipeline. ~500-800 LOC. |
| _open_ | Port Rust replay tool to Go | Closes audit-FULL phase 7 live invocation. ~400-600 LOC. |
| 2026-05-02 | **Port Rust materializer to Go (transforms.ts) — DONE** | `internal/materializer` + `cmd/materializer` + `materializer_smoke.sh`. Ports `transforms.ts` (12 transforms) + `build_evidence_index.ts`. Idempotency, day-partition, receipt. 14 tests green; on-wire JSON matches TS so both runtimes interoperate. |
| 2026-05-02 | **Port Rust replay tool to Go — DONE** | `internal/replay` + `cmd/replay` + `replay_smoke.sh`. Ports `replay.ts` retrieve → bundle → /v1/chat → validate → log. Closes audit-FULL phase 7 live invocation on Go side. 14 tests green; same `data/_kb/replay_runs.jsonl` shape (schema=replay_run.v1) as TS. |
| _open_ | Decide on Lance vector backend | Defer until corpus exceeds ~5M rows. |
| _open_ | Pick Go primary vs Rust primary | Both viable. Go has perf edge after today; Rust has production deploy + producer-side completeness. |

- 2026-05-01 — Recorded Go validator port shipping (`b03521a` golangLAKEHOUSE), updated production-validators section.
- 2026-05-01 — Reframed as living document in `docs/`, added Decisions tracker + Update guidance + Change log sections.
- 2026-05-01 — Multi-tier 100k load test ran (335k scenarios @ 1,115/sec, 4/6 at 0% fail), surfaced coder/hnsw v0.6.1 nil-deref on small playbook_memory index. Recover guard added; real fix open.
- 2026-05-01 (later) — coder/hnsw v0.6.1 panic real fix landed: vectord lifts source-of-truth out of coder/hnsw via `i.vectors` side store + recover wrappers + rebuild fallback. Re-run multitier 60s/conc=50: 0 failures across 19,622 scenarios. STATE_OF_PLAY invariant added to "DO NOT RELITIGATE".
- 2026-05-02 — Substrate fix verified at original failure-surfacing scale. Multitier 5min @ conc=50: 132,211 scenarios at 438/sec, 6/6 classes at 0% failure (was 4/6 pre-fix). Throughput drop (1,115 → 438/sec) is the honest cost of the formerly-broken scenarios doing real HNSW Add work. STATE_OF_PLAY refreshed to 2026-05-02.
- 2026-05-02 — Materializer + replay tool ported from Rust legacy to Go (`internal/materializer` + `internal/replay`, both with CLI + smoke + tests). Both runtimes now produce the same `data/evidence/YYYY/MM/DD/*.jsonl` and `data/_kb/replay_runs.jsonl` shapes; Go side no longer needs Bun for these phases.

| Date | Decision | Effect |
|---|---|---|
| 2026-05-01 | playbook_record under load triggers coder/hnsw v0.6.1 nil-deref | **Recover guard added** in BatchAdd; daemon stays up. **Real fix open**: upstream patch OR small-index custom Add path OR alternate store. |
| 2026-05-01 (later) | **Real fix landed.** vectord lifts source-of-truth out of coder/hnsw via `i.vectors map[string][]float32` side store; `safeGraphAdd`/`safeGraphDelete` recover panics; warm-path Add falls back to rebuild on failure; `rebuildGraphLocked` reads from the panic-safe side map. Re-ran multitier 60s/conc=50: **0 failures across 19,622 scenarios** (was 96-98% on 2/6). p50 on previously-failing scenarios moves 5ms (instant fail) → 551ms (real Add work — honest cost of correctness). Memory cost: ~2× for vectors. STATE_OF_PLAY captures the architecture invariant. |
| 2026-05-02 | **Full-scale verification.** Re-ran multitier at the original failure-surfacing footprint (5min @ conc=50). Result: **132,211 scenarios at 438.5/sec, 0 failures across all 6 classes.** Throughput dropped from pre-fix 1,115/sec → 438/sec because previously-broken scenarios (96-98% fail) now do real HNSW Add work instead of fast nil-deref panics. Healthy tails: `surge_fill_validate` p50=28.9ms / p99=1.53s, `playbook_record_replay` p50=504ms / p99=2.32s — small-index rebuild kicking in under sustained churn, working as designed. **Substrate fix scales beyond the 19.6k-scenario probe; closing the open thread.** |
## Conclusion
The Go substrate handles **335,257 multi-tier scenarios in 5 minutes**
against a 100k corpus, with **4 of 6 scenario classes at 0% failure**
and the remaining 2 exposing a real coder/hnsw v0.6.1 substrate bug
that operators can recover from via DELETE + recreate.
**Pre-fix (2026-05-01):** 335,257 scenarios in 5min, 4/6 classes at 0%
failure, 2/6 hit a coder/hnsw v0.6.1 nil-deref under playbook record
churn. Operator recovery via DELETE + recreate.
**Post-fix (2026-05-02):** 132,211 scenarios in 5min @ conc=50,
**6/6 classes at 0% failure**. Throughput moved 1,115/sec → 438/sec
because the formerly fast-failing scenarios are now doing real HNSW
Add work — that's the honest cost of correctness, not a regression.
The fix (i.vectors side-store + safeGraphAdd recover wrappers +
small-index rebuild threshold of 32 + saveTask write coalescing)
shifts vectord's source-of-truth out of coder/hnsw so panics can't
lose data and the daemon recovers automatically.
This is the most production-shape test we've run. The harness mixes
search, validator calls (in-process), HTTP cross-daemon round-trips,
playbook recording (where the bug surfaces), and cache exercise. The
result is more honest than a single-endpoint load test: 4 workflows
work cleanly at scale, 1 has a bounded substrate issue with a known
recovery path.
playbook recording, and cache exercise. The result is more honest
