validatord: /v1/validate + /v1/iterate HTTP surface (port 3221)
Closes the last "Go primary" backlog item in docs/ARCHITECTURE_COMPARISON.md. Go now owns the entire validator path end-to-end — no Rust dep for staffing safety net. Architecture: cmd/validatord on :3221 hosts both endpoints. Calls chatd directly for the iterate loop's LLM hop (no gateway self-loopback like the Rust shape). Gateway proxies /v1/validate + /v1/iterate to validatord. What's in: - internal/validator/playbook.go — 3rd validator kind (PRD checks: fill: prefix, endorsed_names ≤ target_count×2, fingerprint required) - internal/validator/lookup_jsonl.go — JSONL roster loader (Parquet deferred; producer one-liner documented in package comment) - internal/validator/iterate.go — ExtractJSON helper + Iterate orchestrator with ChatCaller seam for unit tests - cmd/validatord/main.go — HTTP routes, roster load, chat client - internal/shared/config.go — ValidatordConfig + gateway URL field - lakehouse.toml — [validatord] section - cmd/gateway/main.go — proxy routes for /v1/validate + /v1/iterate Smoke: 5/5 PASS through gateway :3110: ✓ playbook happy path ✓ playbook missing fingerprint → 422 schema/fingerprint ✓ phantom candidate W-PHANTOM → 422 consistency ✓ unknown kind → 400 ✓ roster loaded with 3 records go test ./... green across 33 packages.

ADR-006: auth posture for non-loopback deploy + token rotation impl
ADR-003 locked the auth substrate; ADR-006 ratifies the operator
playbook + adds two implementation pieces needed for Sprint 4
deployment: env-resolved tokens and dual-token rotation.
Six decisions locked in docs/DECISIONS.md:
- 6.1: Non-loopback bind requires auth.token (mechanical gate at
shared.Run, already implemented; this ratifies it).
- 6.2: Token from env, not TOML. /etc/lakehouse/auth.env (mode 0600)
loaded by systemd EnvironmentFile=. New TokenEnv field on
AuthConfig defaults to "AUTH_TOKEN".
- 6.3: AllowedIPs for inter-service same-trust-domain; Token for
cross-trust-boundary (gateway ↔ external).
- 6.4: /health stays unauthenticated; everything else under
shared.Run is gated. Already implemented; ratified here.
- 6.5: Token rotation is dual-token. New SecondaryTokens []string
on AuthConfig — both primary and any secondary pass auth
during the rotation window. Implemented in this commit.
- 6.6: TLS terminates at the network edge (nginx/Caddy), not
in-process. Daemons stay HTTP-only; internal traffic stays
on private subnets per Decision 6.3.
Implementation:
- internal/shared/config.go: AuthConfig gains TokenEnv +
SecondaryTokens fields. New resolveAuthFromEnv() called by
LoadConfig fills Token from os.Getenv(TokenEnv) when Token is
empty. TokenEnv defaults to "AUTH_TOKEN" so the happy path needs
no TOML config.
- internal/shared/auth.go: RequireAuth pre-encodes Bearer headers
for primary + every secondary token; per-request constant-time
compare walks the slice. Fast path is 1 compare (primary).
Tests:
- TestLoadConfig_AuthTokenFromEnv (3 sub-tests): default env name,
custom token_env, explicit Token wins over env.
- TestRequireAuth_SecondaryTokenAccepted: both primary + secondary
tokens pass during rotation window.
- TestRequireAuth_SecondaryTokensOnly: only-secondary path works
for the case where primary was just promoted-to-empty mid-rotation.
go test ./internal/shared all green; existing auth_test.go
unchanged (constant-time compare path preserved).

phase 4: chatd — multi-provider LLM dispatcher (ollama / cloud / openrouter / opencode / kimi)
new cmd/chatd on :3220 routes /v1/chat to the right provider based
on model-name prefix or :cloud suffix. closes the architectural gap
named in lakehouse.toml [models]: tiers map to model IDs, but until
phase 4 there was no service that could actually CALL those models
from go.
routing rules (registry.Resolve):
ollama/<m> → local Ollama (prefix stripped)
ollama_cloud/<m> → Ollama Cloud
<m>:cloud → Ollama Cloud (suffix variant — kimi-k2.6:cloud)
openrouter/<v>/<m> → OpenRouter (prefix stripped, OpenAI-compat)
opencode/<m> → OpenCode unified Zen+Go
kimi/<m> → Kimi For Coding (api.kimi.com/coding/v1)
bare names → local Ollama (default)
provider implementations:
- internal/chat/types.go Provider interface, Request/Response, errors
- internal/chat/registry.go prefix + :cloud suffix dispatch
- internal/chat/ollama.go local Ollama via /api/chat (think=false default)
- internal/chat/ollama_cloud.go Ollama Cloud via /api/generate (Bearer auth)
- internal/chat/openai_compat.go shared OpenAI Chat Completions for the
OpenRouter/OpenCode/Kimi family
- internal/chat/builder.go BuildRegistry from BuilderInput;
ResolveKey reads env then .env file fallback
config:
- ChatdConfig in internal/shared/config.go with bind, ollama_url,
per-provider key env names + .env fallback paths, timeout
- Gateway gains chatd_url + /v1/chat + /v1/chat/* routes
- lakehouse.toml [chatd] block with /etc/lakehouse/<provider>.env defaults
tests (19 in internal/chat):
- registry: prefix + :cloud + errors + telemetry + provider listing
- ollama: happy path + prefix strip + format=json + 500 mapping +
flatten_messages
- openai_compat: happy path + format=json + 429 mapping + zero-choices
think=false default in ollama + ollama_cloud — local hot path skips
reasoning, low-budget callers (the playbook_lift judge at max_tokens=10)
get direct answers instead of empty content + done_reason=length.
proven via chatd_smoke acceptance.
acceptance gate: scripts/chatd_smoke.sh — 6/6 PASS:
1. /v1/chat/providers lists exactly registered providers (1 in dev mode)
2. bare model → ollama default with content + token counts + latency
3. explicit ollama/<m> → prefix stripped at upstream
4. <m>:cloud without ollama_cloud registered → 404 (no silent fall-through)
5. unknown/<m> → falls through to default → upstream 502 (no prefix rewrite)
6. missing model field → 400
just verify: PASS (vet + 30 packages × short tests + 9 smokes).
chatd_smoke is a domain smoke (not in just verify, mirrors matrix /
observer / pathway pattern).

phase 1: add [models] tier config — additive, no callers migrate yet
Codifies the small-model-pipeline tiering (per project_small_model_pipeline_vision.md) in lakehouse.toml [models] section. Tier names map to actual model IDs; bumping a model means editing one line, not hunting through code. Tier philosophy: - local_* : on-box Ollama. Inner-loop hot path. Repeated calls. - cloud_* : Ollama Cloud (Pro plan). Larger context, fail-up tier. - frontier_* : OpenRouter / OpenCode. Rate-limited, billed per call. weak_models is the codified "local-hot-path eligible" list — phase 2 will migrate matrix.downgrade to read it instead of hardcoding. Defaults reflect 2026-04-29 architecture: qwen3.5:latest as local (stronger than qwen2.5, same JSON-clean property), kimi-k2.6 as cloud judge (kimi-k2:1t still upstream-broken), opus-4-7 + kimi-k2-0905 as frontier review/arch via OpenRouter, opencode/claude-opus-4-7 as frontier_free leveraging the OpenCode subscription. 3 new tests in internal/shared/config_test.go: - TestDefaultConfig_ModelsTier — locks tier defaults - TestModelsConfig_IsWeak — weak-bypass list - TestLoadConfig_ModelsTOMLRoundTrip — override semantics just verify PASS (g2 had one flake on first run — Ollama transfer truncation; clean on retry, unrelated to this change).

H: observerd — autonomous-iteration witness loop (SPEC §2 port)
Port of the load-bearing pieces of mcp-server/observer.ts (Rust
system, 852 lines TS) per SPEC §2's named target. Implements PRD
loop 3 ("Observer loop — watches each run, refines configs").
Routes (all under /v1/observer/* via gateway):
GET /observer/health — liveness
GET /observer/stats — total / successes / failures /
by_source / recent_scenario_ops
(matches Rust JSON shape exactly)
POST /observer/event — record one ObservedOp; auto-defaults
timestamp + source, validates required
fields (endpoint), persists to JSONL,
appends to ring buffer
Architecture:
- internal/observer/types.go — ObservedOp model + Source taxonomy
(mcp / scenario / langfuse / overseer_correction). Mirrors the
Rust shape so JSON round-trips during cutover.
- internal/observer/store.go — Store + Persistor. Ring buffer cap
matches Rust's 2000; recent_scenarios cap matches Rust's 10.
Same persist-then-apply order as pathwayd; same corruption-
tolerant replay (skip malformed lines + warn).
- cmd/observerd — :3219 HTTP service, fronted by gateway as
/v1/observer/*.
- lakehouse.toml + DefaultConfig — [observerd] block matches the
pathwayd pattern (Bind + PersistPath; empty path = ephemeral).
Tests + smoke (all PASS):
- 7 unit tests in store_test.go: validation, default fields,
stats aggregation, recent-scenarios cap + ordering, ring-buffer
rollover at cap, JSONL round-trip persistence, corruption-
tolerant replay (1 valid + 1 corrupt + 1 valid → 2 applied)
- scripts/observer_smoke.sh: 4 assertions through gateway —
record 5 events (3 ok / 2 fail across 2 sources), stats
aggregates correctly, empty-endpoint→400, kill+restart preserves
via JSONL replay (5 ops, 3 ok, 2 err survive)
Deferred (named in package + cmd doc, not in this commit):
- POST /observer/review (cloud-LLM hand-review fall-back). The
heuristic-only path could land cheaply but the productized
cloud path (qwen3-coder fall-back) is multi-day port.
- Background loops: analyzeErrors, consolidatePlaybooks,
tailOverseerCorrections (read overseer_corrections.jsonl into
the ring buffer once per cycle).
- escalateFailureClusterToLLMTeam (failure clustering trigger
that posts to LLM Team's /api/run with code_review mode).
/relevance is NOT duplicated — already ported in

matrixd: multi-corpus retrieve+merge — SPEC §3.4 component 2 of 5
Lands the matrix indexer's first piece per docs/SPEC.md §3.4:
multi-corpus retrieve+merge with corpus attribution per result.
Future components (relevance filter, downgrade gate, learning-loop
integration) layer on top of this surface.
Architecture:
- internal/matrix/retrieve.go — Retriever takes (query, corpora,
k, per_corpus_k), parallel-fans across vectord indexes, merges
by distance ascending, preserves corpus origin per hit
- cmd/matrixd — HTTP service on :3217, fronts /v1/matrix/*
- gateway proxy + [matrixd] config + lakehouse.toml entry
- Either query_text (matrix calls embedd) or query_vector
(caller pre-embedded) — vector takes precedence if both set
Error policy: fail-loud on any corpus error. Silent partial returns
would lie about coverage, defeating the matrix's whole purpose.
Bubbles vectord errors as 502 (upstream), validation as 400.
Smoke (scripts/matrix_smoke.sh, 6 assertions PASS first try):
- /matrix/corpora lists indexes
- Multi-corpus search returns hits from BOTH corpora
- Top hit is the globally-closest across all corpora
(b-near beats a-near at distance 0.05 vs 0.1 — proves merge)
- Metadata round-trips through the merge
- Distances ascending in result list
- Negative paths: empty corpora → 400, missing corpus → 502,
no query → 400
12-smoke regression sweep all green (D1-D6, G1, G1P, G2,
storaged_cap, pathway, matrix).

embed cache — LRU at /v1/embed for repeat-query elimination
Adds CachedProvider wrapping the embedding Provider with a thread-safe
LRU keyed on (effective_model, sha256(text)) → []float32. Repeat
queries return the stored vector without round-tripping to Ollama.
Why this matters: the staffing 500K test (memory project_golang_lakehouse)
documented that the staffing co-pilot replays many of the same query
texts ("forklift driver IL", "welder Chicago", "warehouse safety", etc).
Each repeat paid the ~50ms Ollama round-trip. Cached repeats now serve
in <1µs (LRU lookup + sha256 of input).
Memory budget: ~3 KiB per entry at d=768. Default 10K entries ≈ 30 MiB.
Configurable via [embedd].cache_size; 0 disables (pass-through mode).
Per-text caching, not per-batch — a batch with mixed hits/misses only
fetches the misses upstream, then merges the result preserving caller
input order. Three-text batch with one miss = one upstream call for
that one text instead of three.
Implementation:
internal/embed/cached.go (NEW, 150 LoC)
CachedProvider implements Provider; uses hashicorp/golang-lru/v2.
Key shape: "<model>:<sha256-hex>". Empty model resolves to
defaultModel (request-derived) for the key — NOT res.Model
(upstream-derived), so future requests with same input shape
hit the same key. Caught by TestCachedProvider_EmptyModelResolvesToDefault.
Atomic hit/miss counters + Stats() + HitRate() + Len().
internal/embed/cached_test.go (NEW, 12 test funcs)
Pass-through-when-zero, hit-on-repeat, mixed-batch only fetches
misses, model-key isolation, empty-model resolves to default,
LRU eviction at cap, error propagation, all-hits synthesized
without upstream call, hit-rate accumulation, empty-texts
rejected, concurrent-safe (50 goroutines × 100 calls), key
stability + distinctness.
internal/shared/config.go
EmbeddConfig.CacheSize (toml: cache_size). Default 10000.
cmd/embedd/main.go
Wraps Ollama Provider with CachedProvider on startup. Adds
/embed/stats endpoint exposing hits / misses / hit_rate / size.
Operators check the rate to confirm the cache is working
(high rate = good) or sized wrong (low rate + many misses on a
workload that should have repeats).
cmd/embedd/main_test.go
Stats endpoint tests — disabled mode shape, enabled mode tracks
hits + misses across repeat calls.
One real bug caught by my own test:
Initial implementation cached under res.Model (upstream-resolved)
rather than effectiveModel (request-resolved). A request with
model="" caching under "test-model" (Ollama's default), then a
request with model="the-default" (our config default) missing
the cache. Fix: always use the request-derived effectiveModel
for keys; that's the predictable side. Locked by
TestCachedProvider_EmptyModelResolvesToDefault.
Verified:
go test -count=1 ./internal/embed/ — all 12 cached tests + 6 ollama tests green
go test -count=1 ./cmd/embedd/ — stats endpoint tests green
just verify — vet + test + 9 smokes 33s
Production benefit:
~50ms Ollama round-trip → <1µs cache lookup for cached entries.
At 10K-entry default + ~30% repeat rate (typical staffing co-pilot
workload), saves several seconds per staffer-query session.

G2: embedd — text → vector via Ollama · 2 scrum fixes
Bridges the missing piece for the staffing co-pilot: text inputs to
vectord-shaped vectors. Standalone cmd/embedd on :3216 fronted by
gateway at /v1/embed. Pluggable embed.Provider interface (G2 ships
Ollama; OpenAI/Voyage swap in via the same interface in G3+).
Wire format:
POST /v1/embed {"texts":[...], "model":"..."} // model optional
→ 200 {"model","dimension","vectors":[[...]]}
Default model: nomic-embed-text (768-d). Ollama returns float64;
provider converts to float32 at the boundary so vectors flow through
vectord/HNSW without re-conversion.
Acceptance smoke 5/5 PASS — including the architectural payoff:
end-to-end embed → vectord add → search by re-embedded text returns
recall=1 at distance 5.96e-8 (float32 precision noise on identical
unit vectors). The staffing co-pilot pipeline (text → vector →
similarity search) is now functional end-to-end.
All 9 smokes (D1-D6 + G1 + G1P + G2) PASS deterministically.
Cross-lineage scrum on shipped code:
- Opus 4.7 (opencode): 0 BLOCK + 4 WARN + 3 INFO
- Kimi K2-0905 (openrouter): 0 BLOCK + 2 WARN + 1 INFO
- Qwen3-coder (openrouter): "No BLOCKs" (3 tokens)
Fixed (2 — 1 convergent + 1 single-reviewer):
C1 (Opus + Kimi convergent WARN): per-text 60s timeout × N-text
batch was up to N×60s with no batch-level cap. One stuck Ollama
call would stall the whole handler indefinitely. Fix:
context.WithTimeout(r.Context(), 60s) wraps the entire batch.
O-W3 (Opus WARN): empty strings in texts went to Ollama unchecked,
producing version-dependent garbage. Fix: reject "" with 400 at
the handler boundary so callers get a deterministic answer
instead of an upstream-conditional 502.
Deferred (4): drainAndClose 64KiB cap (matches G0 pattern), no
concurrency limit on /embed (single-tenant G2), missing Accept
header (exotic-proxy concern), MaxBytesError string-match
redundancy (paranoia layer kept consistent across codebase).
Zero false positives this round — Qwen returned 3 tokens "No BLOCKs"
and the other two reviewers' findings were all real.
Setup confirmed: Ollama 0.21.0 on :11434 with nomic-embed-text loaded.
Per-text /api/embeddings used (forward-compat with 0.21+); newer
0.4+ /api/embed batch endpoint can swap in via the Provider interface.

G1P: vectord persistence to storaged + scrum (3 fixes incl. 3-way convergent)
Adds optional persistence to vectord (G1's HNSW vector search). Single-
file framed format per index — eliminates the torn-write class that
the 3-way convergent scrum finding identified:
_vectors/<name>.lhv1 — single binary blob:
[4 bytes magic "LHV1"]
[4 bytes envelope_len uint32 BE]
[envelope bytes — JSON params + metadata + version]
[graph bytes — raw hnsw.Graph.Export]
Pre-extraction: internal/catalogd/store_client.go → internal/storeclient/
shared package, since both catalogd and vectord need it. Same pattern as
the pre-D5 catalogclient extraction.
Optional via [vectord].storaged_url config (empty = ephemeral mode).
On startup: List + Load each persisted index. After Create / batch Add /
DELETE: Save (or Delete from storaged). Save failures are logged-not-
fatal — in-memory state is the source of truth in flight.
Acceptance smoke G1P 8/8 PASS — kill+restart preserves state, post-
restart search returns dist=0 (graph round-trips exactly), DELETE
removes the file, post-delete restart shows count=0.
All 8 smokes (D1-D6 + G1 + G1P) PASS deterministically. The g1_smoke
gained scripts/g1_smoke.toml that disables persistence so the
in-memory API test stays decoupled from any rehydrate-from-storaged
state contamination.
Cross-lineage scrum on shipped code:
- Opus 4.7 (opencode): 1 BLOCK + 5 WARN + 3 INFO
- Kimi K2-0905 (openrouter): 1 BLOCK + 2 WARN
- Qwen3-coder (openrouter): 2 BLOCK + 2 WARN + 1 INFO
Fixed (3 — 1 convergent + 2 single-reviewer):
C1 (Opus + Kimi + Qwen 3-WAY CONVERGENT WARN): Save was non-atomic
across two PUTs — envelope-succeeds + graph-fails left a half-
saved index that passed the "both present" List filter and
silently mismatched metadata against vectors on Load.
Fix: collapse to single framed file (no torn-write window
possible).
O-B1 (Opus BLOCK): isNotFound substring-matched "key not found"
against the wrapped error message — brittle, any 5xx body
containing that text would silently misclassify as missing.
Fix: errors.Is(err, storeclient.ErrKeyNotFound).
O-I3 (Opus INFO): handleAdd pre-validation only covered id+dim;
NaN/Inf/zero-norm could still fail mid-batch leaving partial
commits. Fix: extend pre-validation to call ValidateVector
(newly exported) per item before any commit.
Dismissed (3 false positives):
K-B1 + Q-B1 ("safeKey double-escapes %2F segments") — false
convergent. Wire-protocol escape is decoded by storaged's chi
router on the way in; on-disk key is the original literal.
%2F round-trips correctly through PathEscape → URL → chi decode
→ S3 key.
Q-B2 ("List vulnerable to race conditions") — vectord is single-
process; no concurrent Save against List in the same vectord.
Deferred (3): rehydrate per-index timeout (G2+ multi-index scale),
saveAfter request ctx (matches G0 timeout deferral), Encode RLock
during slow writer (documented as buffer-only API).
The C1 finding is the strongest signal of the cross-lineage filter:
three independent reviewers all flagged the same torn-write hazard.
Single-file framing eliminates the class — there's now no Persistor
state where envelope and graph can disagree.

G1: vectord — HNSW vector search via coder/hnsw · 6 scrum fixes applied
First G1+ piece. Standalone vectord service with in-memory HNSW
indexes keyed by string IDs and optional opaque JSON metadata.
Wraps github.com/coder/hnsw v0.6.1 (pure Go, no cgo). New port
:3215 with /v1/vectors/* routed through gateway.
API:
POST /v1/vectors/index create
GET /v1/vectors/index list
GET /v1/vectors/index/{name} get info
DELETE /v1/vectors/index/{name}
POST /v1/vectors/index/{name}/add (batch)
POST /v1/vectors/index/{name}/search
Acceptance smoke 7/7 PASS — including recall=1 on inserted vector
w-042 (cosine distance 5.96e-8, float32 precision noise), 200-
vector batch round-trip, dim mismatch → 400, missing index → 404,
duplicate create → 409.
Two upstream library quirks worked around in the wrapper:
1. coder/hnsw.Add panics with "node not added" on re-adding an
existing key (length-invariant fires because internal
delete+re-add doesn't change Len). Pre-Delete fixes for n>1.
2. Delete of the LAST node leaves layers[0] non-empty but
entryless; next Add SIGSEGVs in Dims(). Workaround: when
re-adding to a 1-node graph, recreate the underlying graph
fresh via resetGraphLocked().
Cross-lineage scrum on shipped code:
- Opus 4.7 (opencode): 0 BLOCK + 4 WARN + 3 INFO
- Kimi K2-0905 (openrouter): 2 BLOCK + 2 WARN + 1 INFO
- Qwen3-coder (openrouter): "No BLOCKs" (4 tokens)
Fixed (4 real + 2 cleanup):
O-W1: Lookup returned the raw []float32 from coder/hnsw — caller
mutation would corrupt index. Now copies before return.
O-W3: NaN/Inf vectors poison HNSW (distance comparisons return
false for both < and >, breaking heap invariants). Zero-norm
under cosine produces NaN. Now validated at Add time.
K-B1: Re-adding with nil metadata silently cleared the existing
entry — JSON-omitted "metadata" field deserializes as nil,
making upsert non-idempotent. Now nil = "leave alone"; explicit
{} or Delete to clear.
O-W4: Batch Add with mid-batch failure left items 0..N-1
committed and item N rejected. Now pre-validates all IDs+dims
before any Add.
O-I1: jsonItoa hand-roll replaced with strconv.Itoa — no
measured allocation win.
O-I2: distanceFn re-resolved per Search → use stored i.g.Distance.
Dismissed (2 false positives):
K-B2 "MaxBytesReader applied after full read" — false, applied
BEFORE Decode in decodeJSON
K-W1 "Search distances under read lock might see invalidated
slices from concurrent Add" — false, RWMutex serializes
write-lock during Add against read-lock during Search
Deferred (3): HTTP server timeouts (consistent G0 punt),
Content-Type validation (internal service behind gateway), Lookup
dim assertion (in-memory state can't drift).
The K-B1 finding is worth pausing on: nil metadata on re-add is
the kind of API ergonomics bug only a code-reading reviewer
catches — smoke would never detect it because the smoke always
sends explicit metadata. Three lines changed in Add; the resulting
API matches what callers actually expect.

Real-scale validation post-G0: configurable ingest cap + workers_500k metrics
Validated G0 substrate against the production workers_500k.parquet dataset (18 cols × 500,000 rows). Findings + one applied fix: Finding #1 (FIXED): ingestd's hardcoded 256 MiB cap rejected the 500K CSV (344 MiB) with 413. Cap fired correctly, no OOM. Extracted to [ingestd].max_ingest_bytes config field; default 256 MiB, override per deployment for known-large workloads. With cap bumped to 512 MiB, 500K ingest succeeds in 3.12s with ingestd peak RSS 209 MiB. Finding #2 (deferred): ingestd doesn't release memory between ingests. Go runtime conservative; long-running daemon, fine. Finding #3: DuckDB-via-httpfs is healthy at 500K. GROUP BY 45ms, count(*) 24ms, AVG 47ms, schema introspection 25ms. Sub-linear scaling vs 100K — the s3:// read path is not a bottleneck. Finding #4: ADR-010 type inference correctly handled real staffing data. worker_id → BIGINT, numeric scores → DOUBLE, multi-line resume_text → VARCHAR. 1000-row sample sufficient. Finding #5: Go's encoding/csv handles RFC 4180 quoted-comma fields and multi-line quoted text without LazyQuotes — confirming the D4 scrum's dismissal of Qwen's BLOCK on this point. Net: substrate handles production-scale data with one config knob. No correctness issues, no OOMs, no silent type errors. All 6 G0 smokes still PASS after the cap-config change.

G0 D6: gateway reverse proxy fronting all 4 backing services · 2 scrum fixes · G0 COMPLETE
Last day of Phase G0. Gateway promotes the D1 stub endpoints into
real reverse-proxies on :3110 fronting storaged + catalogd + ingestd
+ queryd. /v1 prefix lives at the edge — internal services route on
/storage, /catalog, /ingest, /sql, with the prefix stripped by a
custom Director per Kimi K2's D1-plan finding.
Routes:
/v1/storage/* → storaged
/v1/catalog/* → catalogd
/v1/ingest → ingestd
/v1/sql → queryd
Acceptance smoke 6/6 PASS — every assertion goes through :3110, none
direct to backing services. Full ingest → storage → catalog → query
round-trip verified end-to-end. The smoke's "rows[0].name=Alice"
assertion is the architectural payoff: five binaries, six HTTP
routes, one round-trip through one edge.
Cross-lineage scrum on shipped code:
- Opus 4.7 (opencode): 1 BLOCK + 2 WARN + 2 INFO
- Kimi K2-0905 (openrouter): 1 BLOCK + 3 WARN + 1 INFO (3 false positives, all from one wrong TrimPrefix theory)
- Qwen3-coder (openrouter): 5 completion tokens — "No BLOCKs."
Fixed (2, both Opus single-reviewer):
O-BLOCK: Director path stripping fails if upstream URL has a
non-empty path. The default Director's singleJoiningSlash runs
BEFORE the custom code, so an upstream like http://host/api
produces /api/v1/storage/... after the join — then TrimPrefix("/v1")
is a no-op because the string starts with /api. Fix: strip /v1
BEFORE calling origDirector. New TestProxy_SubPathUpstream regression
locks this in. Today: bare-host URLs only, dormant — but moving
gateway behind a sub-path in prod would have silently 404'd.
O-WARN2: url.Parse is permissive — typo "127.0.0.1:3211" (no scheme)
parses fine, produces empty Host, every request 502s. mustParseUpstream
fail-fast at startup with a clear message naming the offending
config field.
Dismissed (3, all Kimi, same false TrimPrefix theory):
K-BLOCK "TrimPrefix loops forever on //v1storage" — false, single
check-and-trim, no loop
K-WARN "no upper bound on repeated // removal" — same false theory
K-WARN "goroutines leak if upstream parse fails while binaries
running" — confused scope; binaries are separate OS processes
launched by the smoke script
D1 smoke updated (post-D6): the 501 stub probes are gone (gateway no
longer stubs /v1/ingest and /v1/sql). Replaced with proxy probes that
verify gateway forwards malformed requests to ingestd and queryd. Launch
order changed from parallel to dep-ordered (storaged → catalogd →
ingestd → queryd → gateway) since catalogd's rehydrate now needs
storaged, queryd's initial Refresh needs catalogd.
All six G0 smokes (D1 through D6) PASS end-to-end after every fix
round. Phase G0 substrate is complete: 5 binaries, 6 routes, 25 fixes
applied across 6 days from cross-lineage review.
G1+ next: gRPC adapters, Lance/HNSW vector indices, Go MCP SDK port,
distillation rebuild, observer + Langfuse integration.

G0 D5: queryd DuckDB SELECT over Parquet via httpfs · 4 scrum fixes
Phase G0 Day 5 ships queryd: in-memory DuckDB with custom Connector
that runs INSTALL httpfs / LOAD httpfs / CREATE OR REPLACE SECRET
(TYPE S3) on every new connection, sourced from SecretsProvider +
shared.S3Config. SetMaxOpenConns(1) so registrar's CREATE VIEWs and
handler's SELECTs serialize through one connection (avoids cross-
connection MVCC visibility edge cases).
Registrar.Refresh reads catalogd /catalog/list, runs CREATE OR
REPLACE VIEW "name" AS SELECT * FROM read_parquet('s3://bucket/key')
per manifest, drops views for removed manifests, skips on unchanged
updated_at (the implicit etag). Drop pass runs BEFORE create pass so
a poison manifest can't block other manifest refreshes (post-scrum
C1 fix).
POST /sql with JSON body {"sql":"…"} returns
{"columns":[{"name":"id","type":"BIGINT"},…], "rows":[[…]],
"row_count":N}. []byte → string conversion so VARCHAR rows
JSON-encode as text. 30s default refresh ticker, configurable via
[queryd].refresh_every.
Cross-lineage scrum on shipped code:
- Opus 4.7 (opencode): 1 BLOCK + 4 WARN + 4 INFO
- Kimi K2-0905 (openrouter): 2 BLOCK + 2 WARN + 1 INFO
- Qwen3-coder (openrouter): 2 BLOCK + 1 WARN + 1 INFO
Fixed (4):
C1 (Opus + Kimi convergent): Refresh aborts on first per-view error
→ drop pass first, collect errors, errors.Join. Poison manifest
no longer blocks the rest of the catalog from re-syncing.
B-CTX (Opus BLOCK): bootstrap closure captured OpenDB's ctx →
cancelled-ctx silently fails every reconnect. context.Background()
inside closure; passed ctx only for initial Ping.
B-LEAK (Kimi BLOCK): firstLine(stmt) truncated CREATE SECRET to 80
chars but those 80 chars contained KEY_ID + SECRET prefix → log
aggregator captures credentials. Stable per-statement labels +
redactCreds() filter on wrapped DuckDB errors.
JSON-ERR (Opus WARN): swallowed json.Encode error → silent
truncated 200 on unsupported column types. slog.Warn the failure.
Dismissed (4 false positives):
Qwen BLOCK "bootstrap not transactional" — DuckDB DDL is auto-commit
Qwen BLOCK "MaxBytesReader after Decode" — false, applied before
Kimi BLOCK "concurrent Refresh + user SELECT deadlock" — not a
deadlock, just serialization, by design with 10s timeout retry
Kimi WARN "dropView leaves r.known inconsistent" — current code
returns before the delete; the entry persists for retry
Critical reviewer behavior: 1 convergent BLOCK between Opus + Kimi
on the per-view error blocking, plus two independent single-reviewer
BLOCKs (B-CTX, B-LEAK) that smoke could never have caught. The
B-LEAK fix uses defense-in-depth: never pass SQL into the error
path AND redact known cred values from DuckDB's own error message.
DuckDB cgo path: github.com/duckdb/duckdb-go/v2 v2.10502.0 (per
ADR-001 §1) on Go 1.25 + arrow-go. Smoke 6/6 PASS after every
fix round.

G0 D4: ingestd CSV → Parquet → catalogd register · 2 scrum fixes
Phase G0 Day 4 ships ingestd: multipart CSV upload, Arrow schema
inference per ADR-010 (default-to-string on ambiguity), single-pass
streaming CSV → Parquet via pqarrow batched writer (Snappy compressed,
8192 rows per batch), PUT to storaged at content-addressed key
datasets/<name>/<fp_hex>.parquet, register manifest with catalogd.
Acceptance smoke 6/6 PASS including idempotent re-ingest (proves
inference is deterministic — same CSV always produces same fingerprint)
and schema-drift → 409 (proves catalogd's gate fires on ingest traffic).
Schema fingerprint is SHA-256 over (name, type) tuples in header order
using ASCII record/unit separators (0x1e/0x1f) so column names with
commas can't collide. Nullability intentionally NOT in the fingerprint
— a column gaining nulls isn't a schema change.
Cross-lineage scrum on shipped code:
- Opus 4.7 (opencode): 4 WARN + 3 INFO (after 2 self-retracted BLOCKs)
- Kimi K2-0905 (openrouter): 1 BLOCK + 2 WARN + 1 INFO
- Qwen3-coder (openrouter): 2 BLOCK + 2 WARN + 2 INFO
Fixed (2, both Opus single-reviewer):
C-DRIFT: PUT-then-register on fixed datasets/<name>/data.parquet
meant a schema-drift ingest overwrote the live parquet BEFORE
catalogd's 409 fired → storaged inconsistent with manifest.
Fix: content-addressed key datasets/<name>/<fp_hex>.parquet.
Drift writes to a different file (orphan in G2 GC scope); the
live data is never corrupted.
C-WCLOSE: pqarrow.NewFileWriter not Closed on error paths leaks
buffered column data + OS resources per failed ingest.
Fix: deferred guarded close with wClosed flag.
Dismissed (5, all false positives):
Qwen BLOCK "csv.Reader needs LazyQuotes=true for multi-line" — false,
Go csv handles RFC 4180 multi-line quoted fields by default
Qwen BLOCK "row[i] OOB" — already bounds-checked at schema.go:73
and csv.go:201
Kimi BLOCK "type assertion panic if pqarrow reorders fields" —
speculative, no real path
Kimi WARN + Qwen WARN×2 "RecordBuilder leak on early error" —
false convergent. Outer defer rb.Release() captures the current
builder; in-loop release runs before reassignment. No leak.
Deferred (6 INFO + accepted-with-rationale on 3 WARN): sample
boundary type mismatch (G0 cap bounds peak), string-match
paranoia on http.MaxBytesError, multipart double-buffer (G2 spool-
to-disk), separator validation, body close ordering, etc.
The D4 scrum produced fewer real findings than D3 (2 vs 6) — both
were architectural hazards smoke wouldn't catch because the smoke's
"schema drift → 409" assertion was passing even in the corrupted-
state world. The 409 fires correctly; what was wrong was the PUT
having already mutated the live parquet before the validation check.
Opus's PUT-then-register read of the order is exactly the kind of
architectural insight the cross-lineage scrum is designed to surface.

G0 D3: catalogd Parquet manifests + ADR-020 idempotent register · 6 scrum fixes
Phase G0 Day 3 ships catalogd: Arrow Parquet manifest codec, in-memory registry with the ADR-020 idempotency contract (same name+fingerprint reuses dataset_id; different fingerprint → 409 Conflict), HTTP client to storaged for persistence, and rehydration on startup. Acceptance smoke 6/6 PASSES end-to-end including rehydrate-across-restart — the load-bearing test that the catalog/storaged service split actually preserves state. dataset_id derivation diverges from Rust: UUIDv5(namespace, name) instead of v4 surrogate. Same name on any box generates the same dataset_id; rehydrate after disk loss converges to the same identity rather than silently re-issuing. Namespace pinned at a8f3c1d2-4e5b-5a6c-9d8e-7f0a1b2c3d4e — every dataset_id ever issued depends on these bytes. Cross-lineage scrum on shipped code: - Opus 4.7 (opencode): 1 BLOCK + 5 WARN + 3 INFO - Kimi K2-0905 (openrouter, validated D2): 2 BLOCK + 2 WARN + 1 INFO - Qwen3-coder (openrouter): 2 BLOCK + 2 WARN + 2 INFO Fixed: C1 list-offsets BLOCK (3-way convergent) → ValueOffsets(0) + bounds C2 Rehydrate mutex held across I/O → swap-under-brief-lock pattern S1 split-brain on persist failure → candidate-then-swap S2 brittle string-match for 400 vs 500 → ErrEmptyName/ErrEmptyFingerprint sentinels S3 Get/List shallow-copy aliasing → cloneManifest deep copy S4 keep-alive socket leak on error paths → drainAndClose helper Dismissed (false positives, all single-reviewer): Kimi BLOCK "Decode crashes on empty Parquet" — already handled Kimi INFO "safeKey double-escapes" — wrong, splitting before escape is required Qwen INFO "rb.NewRecord() error unchecked" — API returns no error Deferred to G1+: name validation regex, per-call deadlines, Snappy compression, list pagination continuation tokens (storaged caps at 10k with sentinel for now). Build clean, vet clean, all tests pass, smoke 6/6 PASS after every fix round. arrow-go/v18 + google/uuid added; Go 1.24 → 1.25 forced by arrow-go's minimum.

G0 D1 hardened: 3-lineage scrum review on shipped code · 7 fixes applied
Code-review pass after D1 shipped, all three model lineages running in parallel against the actual Go source (not docs): Convergent findings (≥2 reviewers — high confidence): - C1 BLOCK · Run() errCh/select race could silently drop fast bind errors. Fixed: net.Listen() now runs synchronously before the goroutine; bind errors surface as Run()'s return value. - C2 BLOCK · scripts/d1_smoke.sh sleep 0.5 races bind on cold boxes. Fixed: replaced with poll_health() loop, 5s/svc budget, 50ms poll. - C3 WARN · LoadConfig silent fallback when file missing. Fixed: emits slog.Warn with path + hint when path given but file absent. Single-reviewer fixes: - S1 WARN · slog.SetDefault inside Run() mutated global state from a library function. Fixed: Run() no longer calls SetDefault. - S2 WARN · os.IsNotExist → errors.Is(err, fs.ErrNotExist) idiom. - S6 WARN · smoke double-curl collapsed to single curl -i parse. Second-pass Opus review on post-fix code caught one more: - head -1 on curl -i fragile against 1xx interim lines. Fixed: awk picks the last HTTP/* status line (robust to 100 Continue). Accepted with rationale (deferred or planned): - S3 secrets-in-lakehouse.toml: D2.3 SecretsProvider already planned - S4 5x cmd/*/main.go duplication: defer until D2 reveals real per-service config consumption - S5 /health log volume: defer post-G0, not on k8s yet - 2nd-pass theoreticals: clean-exit-no-Shutdown path doesn't trigger, defensive defer ln.Close() aspirational, etc. Verification: - go build ./cmd/... exit 0 - go vet ./... clean - ./scripts/d1_smoke.sh D1 acceptance gate: PASSED - 3-lineage code review · 14 findings · 7 fixed · 0 deferred · 5 accepted with rationale Total D1 review coverage across the phase: - 3 doc-review passes (Opus + Kimi + Qwen) — 13 findings, 10 fixed - 1 runtime smoke — 1 finding (port 3100 collision), fixed - 1 code-review parallel pass — 14 findings, 7 fixed - 1 code-review second pass (Opus) — 1 actionable, fixed - Cumulative: 29 findings · 19 fixed inline · 5 accepted · 5 deferred Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

G0 D1 ships: skeleton + chi + /health × 5 binaries · acceptance gate PASSED
Phase G0 Day 1 executed end-to-end after a third-pass review by
qwen3-coder:480b consolidated all findings across Opus/Kimi/Qwen
lineages.
Cross-lineage review consolidation (3 model passes + 1 runtime pass):
- Opus 4.7: 9 findings · 7 fixed inline · 2 deferred
- Kimi K2.6: 2 BLOCKs (introduced by Opus fixes) · 2 fixed
- Qwen3-coder:480b: 2 WARNs · 1 fixed (D2.4 256 MiB cap + 4-slot
semaphore on PUTs) · 1 deferred (Q2 view refresh batching)
- Runtime smoke: 1 finding (port 3100 collision with live Rust
lakehouse) · fixed (Go dev ports shifted to 3110+)
- Total: 14 findings · 11 fixed · 3 deferred to G2
What landed in code:
- internal/shared/server.go — chi factory, slog JSON, /health,
graceful shutdown via signal.NotifyContext
- internal/shared/config.go — TOML loader, DefaultConfig, -config flag
- cmd/{gateway,storaged,catalogd,ingestd,queryd}/main.go — five
binaries, each ~30 lines using the shared factory
- lakehouse.toml — G0 dev defaults (3110-3214)
- scripts/d1_smoke.sh — repeatable smoke that exits 0 on PASS
- go.mod / go.sum — chi v5.2.5, pelletier/go-toml/v2 v2.3.0
Verified end-to-end via scripts/d1_smoke.sh:
- All 5 /health endpoints return 200 with correct service name
- Gateway /v1/ingest + /v1/sql stubs return 501 with X-Lakehouse-Stub
- Graceful shutdown logs cleanly on SIGTERM
- DuckDB cgo path verified separately (sql.Open("duckdb","") + ping)
D1 ACCEPTANCE GATE: PASSED.
Next: D2 — storaged S3 GET/PUT/LIST against MinIO.
