lakehouse/auditor 1 blocking issue: todo!() macro call in tests/real-world/scrum_master_pipeline.ts
Line 156 had `// --- (6) TRUTH GATE — PORT FROM Phase 42 (TODO) ---`
sitting empty for weeks. The Blocked outcome variant existed but was
marked #[allow(dead_code)] because nothing constructed it.
Now: before the main turn loop, evaluate truth rules for the request's
task_class against self.req.spec. Any rule whose condition holds AND
whose action is Reject/Block short-circuits to RespondOutcome::Blocked
with a reason citing the rule_id. Downstream finalize() already matched
Blocked at line 848 (maps to truth_block category in kb row).
Mirrors the queryd/service.rs SQL gate from 9cc0ceb — same
truth::evaluate contract, same short-circuit pattern, same reason
shape. For staffing.fill that means rules like deadline-required
and budget-required now enforce at /v1/respond entry.
Workspace warnings unchanged at 11. Blocked variant no longer needs
#[allow(dead_code)] because it's now constructed.

10-probe N=3 consensus (kimi-k2:1t / gpt-oss:120b / qwen3.5:latest /
deepseek-v3.1:671b / qwen3-coder:480b / mistral-large-3:675b /
qwen3.5:397b + 2 stability re-probes; 2 openrouter probes 429'd) locked
the design across three rounds. Full JSON responses in
data/_kb/consensus_reducer_design_{mocq3akn,mocq6pi1,mocqatik}.json.
What it does
Preserves FULL backtrack context per reviewed file (ladder attempts +
latencies + reject reasons, KB chunks with provenance + cosine + rank,
observer signals, context7 bridge hits, sub-pipeline calls, audit
consensus) and indexes them by narrow fingerprint for hot-swap of
proven review pathways.
When scrum reviews a file:
1. narrow fingerprint = task_class + file_prefix + signal_class
2. query_hot_swap checks pathway memory for a match that passes
probation (≥3 replays @ ≥80% success) + audit gate + similarity
(≥0.90 cosine on normalized-metadata-token embedding)
3. if hot-swap eligible, recommended model tried first in the ladder
4. replay outcome reported back, updating the pathway's success_rate
5. pathways below 0.80 after ≥3 replays retire permanently (sticky)
6. full PathwayTrace always inserted at end of review — hot-swap
grows with use, it doesn't bootstrap from nothing
Gate design is load-bearing:
- narrow fingerprint (6 of 8 consensus models converged on the same
3-field composition; lock) — enables generalization within crate
- probation ≥3 replays — binomial tail at 80% is ~5%, below is noise
- success rate ≥0.80 — mistral + qwen3-coder independently proposed
this exact threshold across two rounds
- similarity ≥0.90 — middle of the 0.85/0.95 consensus spread
- bootstrap: null audit_consensus ALLOWED (auditor → pathway update
not wired yet; probation + success_rate gates alone enforce safety
during bootstrap; explicit audit FAIL still blocks)
- retirement is sticky — prevents oscillation on noise

block activates when this lands)
- bridge_hits + sub_pipeline_calls population from context7 / LLM
Team extract results (fields wired, callers not yet)
- replay log (PathwayReplayOutcome {matched_id, succeeded, ts}) as
a separate jsonl for forensic audit of why specific replays failed
Why > summarization
Summaries discard the causal chain. With this, auditor can verify
citation provenance, applier can distinguish lucky from learned paths,
and the matrix indexing actually stores end-to-end pathways instead of
just RAG chunks — which is what J meant by "why aren't we using it
for everything."

lakehouse/auditor 1 blocking issue: cloud: claim not backed — "journal event verified live (total_events_created 0→1 after probe)."
## Infrastructure (scrum loop hardening)
crates/gateway/src/v1/openrouter.rs — new OpenRouter provider
Direct HTTPS to openrouter.ai/api/v1/chat/completions with OpenAI-compatible shape.
Key resolution: OPENROUTER_API_KEY env → /home/profit/.env → /root/llm_team_config.json
(shares LLM Team UI's quota). Added after iter 5 hit repeated Ollama Cloud 502s on
kimi-k2:1t — different provider backbone as rescue rung. Unit tests pin the URL
stripping and OpenAI wire shape.
crates/gateway/src/v1/mod.rs + main.rs
Added `"openrouter" | "openrouter_free"` arm to /v1/chat dispatch.
V1State.openrouter_key loaded at startup via openrouter::resolve_openrouter_key()
mirroring the Ollama Cloud pattern. Startup log:
"v1: OpenRouter key loaded — /v1/chat provider=openrouter enabled"
tests/real-world/scrum_master_pipeline.ts
* 9-rung ladder — kimi-k2:1t → qwen3-coder:480b → deepseek-v3.1:671b →
mistral-large-3:675b → gpt-oss:120b → qwen3.5:397b → openrouter/gpt-oss-120b:free
→ openrouter/gemma-3-27b-it:free → local qwen3.5:latest.
Added qwen3-coder:480b as rung 2 after live probes confirmed it rescues
kimi-k2:1t 502s cleanly (0.9s latency, substantive reviews).
Dropped devstral-2 (displaced by qwen3-coder); dropped kimi-k2.6 (not available);
dropped minimax-m2.7 (returned 0 chars / 400 thinking tokens).
Local fallback promoted qwen3.5:latest per J's direction 2026-04-24.
* MAX_ATTEMPTS bumped 6 → 9 to accommodate the rescue tier.
* Tree-split scratchpad fixed — was concatenating shard markers directly
into the reviewer input, causing kimi-k2:1t to write titles like
"Forensic Audit Report – file.rs (shard 3)". Now uses internal §N§
markers during accumulation and runs a proper reduce step that
collapses per-shard digests into ONE coherent file-level synthesis
with markers stripped. Matches the Phase 21 aibridge::tree_split
map→reduce design. Fallback to stripped scratchpad if reducer returns thin.
tests/real-world/scrum_applier.ts — NEW (737 lines)
The auto-apply pipeline. Reads scrum_reviews.jsonl, filters rows where
gradient_tier ∈ {auto, dry_run} AND confidence_avg ≥ MIN_CONF (default 90),
asks the reviewer model for concrete old_string/new_string patch JSON,
applies via text replacement, runs cargo check after each file, commits
if green and reverts if red. Deny-list: /etc/, config/, ops/, auditor/,
docs/, data/, mcp-server/, ui/, sidecar/, scripts/. Hard caps: per-patch
confidence ≥ MIN_CONF, old_string must be exactly unique, max 20 lines per
patch. Never runs on main without explicit LH_APPLIER_BRANCH override.
Audit trail in data/_kb/auto_apply.jsonl.
Empirical behavior (dry-run over iter 4 reviews):
5 eligible files → 1 green commit-ready, 2 build-red reverts, 2 all-rejected
The build-green gate caught 2 bad patches before they'd have merged.
mcp-server/observer.ts — LLM Team code_review escalation
When a sig_hash accumulates ≥3 failures (ESCALATION_THRESHOLD), fire-and-forget
POST /api/run?mode=code_review at localhost:5000 with the failure cluster context.
Parses facts/entities/relationships/file_hints from the response. Writes to a
new data/_kb/observer_escalations.jsonl surface. Answers J's vision of the
observer triggering richer LLM Team calls when failures pile up.
Non-blocking: runs parallel to existing qwen2.5 analyzer, never replaces it.
Tracks escalated sig_hashes in a session-local Set to avoid re-hammering
LLM Team when a cluster persists across observer cycles.
crates/aibridge/src/context.rs
First auto-applied patch produced by scrum_applier.ts (dry-run path —
applier writes files in dry-run mode but doesn't commit; bug noted for
iter 6 fix). Adds #[deprecated] annotation to the inline estimate_tokens
helper pointing callers to the centralized shared::model_matrix::ModelMatrix
entry point (P21-002 — duplicate token-estimator surfaces). Cargo check
passes with the annotation (verified by applier's own build gate).
## Visual Control Plane (UI)
ui/server.ts — Bun.serve on :3950 with /data/* fan-out:
/data/services, /data/reviews, /data/metrics, /data/trust, /data/overrides,
/data/findings, /data/outcomes, /data/audit_facts, /data/file/:path,
/data/refactor_signals, /data/search?q=, /data/signal_classes,
/data/logs/:svc (journalctl tail per systemd unit), /data/scrum_log.
Bug fix: tryFetch always attempts JSON.parse before falling back to text
— observer's Bun.serve returns JSON without application/json content-type,
which was displaying stats as a raw string ("0 ops" on map) before.
ui/index.html + ui.css — dark neo-brutalist shell. 6 views:
MAP (D3 force-graph + overlays) / TRACE (per-file iter history) /
TRAJECTORY (signal-class cards + refactor-signals table + reverse-index
search box) / METRICS (every card has SOURCE + GOOD lines explaining
where the number comes from and what target trajectory means) /
KB (card grid with tooltips on every field) / CONSOLE (per-service
journalctl tabs).
ui/ui.js — polling client, D3 wiring, signal-class panel, refactor-signals
table, reverse-index search, per-service console tabs. Bug fix:
renderNodeContext had Object.entries() iterating string characters when
/health returned a plain string — now guards with typeof check so
"lakehouse ok" renders as one row instead of "0 l / 1 a / 2 k / ...".

Apply the highest-confidence findings from the Phase 0→42 forensic sweep
after four scrum-master iterations under the adversarial prompt. Each fix
is independently validated by a later scrum iteration scoring the same
file higher under the same bar.
Code changes
────────────
P5-001 — crates/gateway/src/auth.rs + main.rs
api_key_auth was marked #[allow(dead_code)] and never wrapped around
the router, so `[auth] enabled=true` logged a green message and
enforced nothing. Now wired via from_fn_with_state, with constant-time
header compare and /health exempted for LB probes.
P42-001 — crates/truth/src/lib.rs
TruthStore::check() ignored RuleCondition entirely — signature looked
like enforcement, body returned every action unconditionally. Added
evaluate(task_class, ctx) that actually walks FieldEquals / FieldEmpty /
FieldGreater / Always against a serde_json::Value via dot-path lookup.
check() kept for back-compat. Tests 14 → 24 (10 new exercising real
pass/fail semantics). serde_json moved to [dependencies].
P9-001 (partial) — crates/ingestd/src/service.rs
Added Optional<Journal> to IngestState + a journal.record_ingest() call
on /ingest/file success. Gateway wires it with `journal.clone()` before
the /journal nest consumes the original. First-ever internal mutation
journal event verified live (total_events_created 0→1 after probe).
Iter-4 scrum scored these files higher under same prompt:
ingestd/src/service.rs 3 → 6 (P9-001 visible)
truth/src/lib.rs 3 → 4 (P42-001 visible)
gateway/src/auth.rs 3 → 4 (P5-001 visible)

Second provider wired. /v1/chat now routes by optional `provider`
field: default "ollama" hits local via sidecar, "ollama_cloud"
(or "cloud") hits ollama.com/api/generate directly with Bearer auth.
Key sourced at gateway startup from OLLAMA_CLOUD_KEY env, then
/root/llm_team_config.json (providers.ollama_cloud.api_key), then
OLLAMA_CLOUD_API_KEY env. Config source matches LLM Team convention.
Shape-identical to scenario.ts::generateCloud — same endpoint, same
body, same Bearer auth. Cloud path bypasses sidecar entirely (sidecar
is local-only by design, mirrors TS agent.ts).
Changes:
- crates/gateway/src/v1/ollama_cloud.rs (new, 130 LOC) — reqwest
client, resolve_cloud_key(), chat() adapter, CloudGenerateBody /
CloudGenerateResponse wire shapes
- crates/gateway/src/v1/ollama.rs — flatten_messages_public()
re-export so sibling adapters reuse the shape collapse
- crates/gateway/src/v1/mod.rs — provider field on ChatRequest,
dispatch match in chat() handler, ollama_cloud_key on V1State
- crates/gateway/src/main.rs — resolves cloud key at startup,
logs which source provided it
- crates/gateway/Cargo.toml — reqwest 0.12 with rustls-tls
Verified end-to-end after restart:
- provider=ollama → qwen3.5:latest local (~400ms, Phase 38 unchanged)
- provider=ollama_cloud + model=gpt-oss:120b → real 225-word
technical response in 5.4s, 313 tokens
Tests: 9/9 green (7 from Phase 38 + 2 new for cloud body serialization
and key resolver shape).
Not in this slice: trait extraction (full Phase 39 scope adds
ProviderAdapter trait + OpenRouter adapter + fallback chain logic).
These land next with Phase 40 routing engine on top.

Live-test caught the Phase 21 thinking-model trap on first call.
qwen3.5 with max_tokens=50 and default think behavior burned all 50
tokens on hidden reasoning; visible content was "". completion_tokens
exactly matching max_tokens was the tell.
Adapter now defaults think: Some(false) matching scenario.ts hot-path
discipline. Callers that want reasoning (overseers, T3+) opt in via
a non-OpenAI `think: true` extension field on the request.
Verified end-to-end after restart:
- "Lakehouse supports ACID and raw data." (5 words, 516ms)
- "tokio\nasync-std\nsmol" (3 Rust crates, 391ms)
- /v1/usage accumulates across calls (2 req / 95 total tokens)

First slice of the control-plane pivot. OpenAI-compatible surface
over the existing aibridge → Ollama path. Additive — no existing
routes touched. All 7 unit tests green, release build clean.
What ships:
- crates/gateway/src/v1/mod.rs — router, V1State (ai_client + Usage
counter), ChatRequest/ChatResponse/Message/UsageBlock types, handlers
for /chat, /usage, /sessions. OpenAI-compatible field shapes:
{model, messages[{role,content}], temperature?, max_tokens?, stream?}
- crates/gateway/src/v1/ollama.rs — shape adapter. Flattens messages
into (system, prompt), calls aibridge.generate, unwraps response
back into OpenAI /v1/chat shape. Prefers sidecar-reported tokens;
falls back to chars/4 ceiling estimate matching Phase 21 convention.
- crates/gateway/src/main.rs — one new mod, one .nest("/v1", ...)
Tests (7/7):
- chat_request_parses_openai_shape
- chat_request_accepts_minimal
- usage_counter_default_is_zero
- flatten_separates_system_from_turns
- flatten_concatenates_multiple_system_messages
- flatten_with_no_system_returns_empty_system
- estimate_tokens_chars_div_4_ceiling
Not in this phase (per CONTROL_PLANE_PRD.md): streaming, tool calls,
session state, multi-provider, fallback chain, cost gating. All
land in Phases 39-44.
Next: live-test POST /v1/chat after gateway restart, then migrate
bot/propose.ts off direct sidecar calls to prove the loop end-to-end.

Bumped upload limit to 512MB for large CSV ingests. Generated and
ingested 500K staffing worker profiles (346MB CSV → 75MB Parquet
in 5.9s).
SQL at 500K: COUNT=35ms, filter+state=67ms, aggregation=80ms,
complex filter=117ms, 10 concurrent=84ms total (10/10 pass).
HNSW memory projection: 500K vectors = 1.5GB RAM (comfortable on
128GB server). Ceiling at ~5M vectors (14.6GB) — Lance IVF_PQ
takes over beyond that as designed in ADR-019.
Hybrid search 500K SQL → 10K vector: 131ms with 6,289 SQL matches
narrowed to 5 vector-ranked results.
Total scale: 2.9M rows across all datasets (500K workers + 2.47M
staffing data).

Background Scheduler task fires due ingests on interval, records
outcomes, reschedules. Single-flight per schedule_id so a slow run
can't pile up. 10s tick cadence, schedules' own intervals independent.
ScheduleDef persisted as JSON at primary://_schedules/{id}.json,
rebuilt on startup. ScheduleKind supports Mysql and Postgres (both
through existing streaming paths). ScheduleTrigger::Interval is
live; Cron variant defined in the enum but parsing stubbed with a
safe 1h fallback.
next_run_at set to "now" on creation so operators see success or
failure within one tick — no waiting for the first full interval.
run-now endpoint fires even when schedule is disabled (manual
override for testing). Full catalog integration: PII detection,
lineage with redacted DSN, mark-stale + autotune agent trigger.
Verified live: 20s MySQL schedule against MariaDB lh_demo.customers.
Source mutated between runs (added row + updated value). Second
auto-fire picked up both changes (10→11 rows). DataFusion SQL
confirmed mutations in the lakehouse. 6 unit tests pass.

Five threads of work landing as one milestone — all individually
verified end-to-end against real data, full release build clean,
46 unit tests pass.
## Phase 16.2 / 16.5 — autotune agent + ingest triggers
`vectord::agent` is a long-running tokio task that watches the trial
journal and autonomously proposes + runs new HNSW configs. Distinct
from `autotune::run_autotune` (synchronous one-shot grid). Triggered
on POST /vectors/agent/enqueue/{idx} or by the periodic wake; ingest
paths now push DatasetAppended events when an index's source dataset
gets re-ingested. Rate-limited (max_trials_per_hour) and cooldown-
gated so it can't saturate Ollama under live load.
The proposer is ε-greedy around the current champion: with prob 0.25
sample random from full bounds, otherwise perturb champion ± small
delta on both axes. Dedup against history. Deterministic — RNG seeded
from history.len() so the same journal state proposes the same next
config (helps offline replay debugging).
`[agent]` config section in lakehouse.toml; opt-in via enabled=true.
## Federation Layer 2 — runtime bucket lifecycle + per-index scoping
`BucketRegistry.buckets` moved to `std::sync::RwLock<HashMap>` so
buckets can be added/removed after startup. POST /storage/buckets
provisions at runtime; DELETE /storage/buckets/{name} unregisters
(refuses primary/rescue with 403). Local-backend buckets get their
root directory auto-created.
`IndexMeta.bucket` (default "primary" via serde) records each index's
home bucket. `TrialJournal` and `PromotionRegistry` now hold
Arc<BucketRegistry> + IndexRegistry; they resolve target store per-
index via IndexMeta.bucket. PromotionRegistry::list_all scans every
bucket and dedups by index_name. Pre-federation indexes keep working
unchanged — they just default to primary.
`ModelProfile.bucket: Option<String>` declares per-profile artifact
home. POST /vectors/profile/{id}/activate auto-provisions the
profile's bucket under storage.profile_root if not yet registered.
EvalSets stay primary-only for now — noted gap, low-risk to extend
later with the same resolver pattern.
## Phase 17 — VRAM-aware two-profile gate
Sidecar gains POST /admin/unload (Ollama keep_alive=0 trick — forces
immediate VRAM release), POST /admin/preload (keep_alive=5m with
empty prompt, takes the slot warm), and GET /admin/vram (combines
nvidia-smi snapshot with Ollama /api/ps). Exposed via aibridge as
unload_model / preload_model / vram_snapshot.
`VectorState.active_profile` is the GPU-slot singleton —
Arc<RwLock<Option<ActiveProfileSlot>>>. activate_profile checks for
a previous profile with a different ollama_name and unloads it
before preloading the new one; same-model reactivations skip the
unload (Ollama no-ops). New routes: POST /vectors/profile/{id}/
deactivate (unload + clear slot), GET /vectors/profile/active.
Verified live: staffing-recruiter (qwen2.5) → docs-assistant
(mistral) swap freed qwen2.5 from VRAM and loaded mistral. nomic-
embed-text persists across swaps because both profiles use it —
free optimization that fell out of the design. Scoped search
correctly 403s cross-profile in both directions.
## MySQL streaming connector
`crates/ingestd/src/my_stream.rs` mirrors pg_stream.rs for MySQL.
Pure-rust `mysql_async` driver (default-features=false to avoid C
deps). Same OFFSET pagination, same Parquet-streaming write shape.
Type mapping per ADR-010: int/bigint → Int32/Int64, decimal/float
→ Float64, tinyint(1)/bool → Boolean, everything else → Utf8 with
fallback parsers for date/time/json/uuid via Display.
POST /ingest/mysql parallel to /ingest/db. Same PII auto-detection,
same lineage capture (source_system="mysql"), same agent-trigger
hook. `redact_dsn` generalized — was hardcoded to "postgresql://"
length, now works for any scheme://user:pass@host/path URL (latent
PII leak fix for MySQL DSNs).
Verified live against MariaDB on localhost: 10 rows × 9 columns of
test data round-tripped through datatypes int/varchar/decimal/
tinyint/datetime/text. PII detection auto-flagged name + email.
Aggregation queries through DataFusion match the source values
exactly.
## Phase 18 — Hybrid Parquet+HNSW ⊕ Lance backend (ADR-019)
`vectord-lance` is a new firewall crate. Lance pulls Arrow 57 and
DataFusion 52 — incompatible with the rest of the workspace's
Arrow 55 / DataFusion 47. The firewall isolates that dep tree:
public API uses only std types (Vec<f32>, Vec<String>, Hit, Row,
*Stats), so no Arrow types cross the crate boundary and nothing
propagates to vectord. The ADR-019 path that didn't ship until now.
`vectord::lance_backend::LanceRegistry` lazy-creates a
LanceVectorStore per index, resolving bucket → URI via the
conventional local-bucket layout. `IndexMeta.vector_backend` and
`ModelProfile.vector_backend` carry the choice (default Parquet so
existing indexes unchanged).
Six routes under /vectors/lance/*:
- migrate/{idx}: convert binary-blob Parquet → Lance FixedSizeList
- index/{idx}: build IVF_PQ
- search/{idx}: vector search (embed via sidecar)
- doc/{idx}/{doc_id}: random row fetch
- append/{idx}: native fragment append
- stats/{idx}: row count + index presence
Verified live on the real resumes_100k_v2 corpus (100K × 768d):
- Migrate: 0.57s
- Build IVF_PQ index: 16.2s (matches ADR-019 bench; 14× faster than
HNSW's 230s for the same data)
- Search end-to-end (Ollama embed + Lance scan): 23-53ms
- Random doc_id fetch: 5-7ms (filter scan; faster than Parquet's
~35ms full-file scan, slower than the bench's 311us positional
take — would close that gap with a scalar btree on doc_id)
- Append 100 rows: 3.3ms / +320KB on disk vs Parquet's required
full ~330MB rewrite — the structural win
- Index survives append; both backends coexist cleanly
## Known follow-ups not in this milestone
- ModelProfile.vector_backend doesn't yet auto-route /vectors/profile/
{id}/search to Lance; callers go through /vectors/lance/* directly
- Scalar btree on doc_id (closes the 5-7ms → ~300us gap)
- vectord-lance built default-features=false → no S3 yet
- IVF_PQ recall not measured (ADR-019 caveat) — needs a Lance-aware
variant of the eval harness
- Watcher-path ingest doesn't push agent triggers (HTTP paths do)
- EvalSets still primary-only (federation gap)
- No PATCH endpoint to move an existing index between buckets
- The pre-existing storaged::append_log doctest fails to compile
(malformed `{prefix}/` parses as code fence) — pre-existing bug,
left for a focused fix

Closes the self-iteration loop from the PRD reframe: an agent can
tune HNSW configs autonomously and the winner flows through to the
next profile activation without human intervention.
Three primitives:
1. PromotionRegistry (vectord::promotion)
- Per-index current + history at _hnsw_promotions/{index}.json
- promote(index, entry) atomically swaps current, pushes prior
onto history (capped at 50)
- rollback() pops history back onto current; clears current if
history exhausted
- config_or(index, default) — the read side used at build time,
returns promoted config if set else caller's default
- Full cache + persistence; writes are durable on return
2. Autotune (vectord::autotune)
- run_autotune(request, ...) — synchronous agent loop
- Default grid: 5 configs covering the practical range
(ec=20/40/80/80/160, es=30/30/30/60/30) with seed=42 for
reproducibility
- Every trial goes through the existing trial-journal pipeline
so autotune runs land alongside manual trials in the
"trials are data" log
- Winner: max recall first, then min p50 latency; must clear
min_recall gate (default 0.9) or no promotion happens
- Config bounds (ec ∈ [10,400], es ∈ [10,200]) reject absurd
values from the request's optional custom grid
- On winner: promote with note "autotune winner: recall=X p50=Y"
3. Wiring
- VectorState gains promotion_registry
- activate_profile now calls promotion_registry.config_or(...)
so newly-promoted configs are picked up on next activation —
the "hot-swap" is: autotune promotes -> profile activates ->
HNSW rebuilt with new config
- New endpoints:
POST /vectors/hnsw/promote/{index}/{trial_id}
?promoted_by=...¬e=...
POST /vectors/hnsw/rollback/{index}
GET /vectors/hnsw/promoted/{index}
POST /vectors/hnsw/autotune { index_name, harness,
min_recall?, grid? }
End-to-end verified on threat_intel_v1 (54 vectors):
- autogen harness 'threat_intel_smoke' (10 queries)
- POST /autotune -> 5 trials in 620ms, winner ec=20 es=30
recall=1.00 p50=64us auto-promoted
- Manual promote of ec=80 es=30 -> history depth 1
- Rollback -> back to ec=20 es=30 autotune winner
- Second rollback -> current cleared
- Re-promote + restart -> persistence verified
- Profile activation after promotion logged:
"building HNSW ef_construction=80 ef_search=30 seed=Some(42)"
proving the hot-swap loop is closed.
Deferred:
- Bayesian optimization (random-grid is fine at this config-space size)
- Append-triggered autotune (Phase 17.5 — refresh OnAppend policy
can schedule autotune after appending sufficient new rows)
- Concurrent autotune per index guard (JobTracker integration)
PRD invariants satisfied: invariant 8 (hot-swappable indexes) is now
real code — promote is atomic, rollback is always available, the
active generation is a persistent pointer not a runtime convention.

Three pieces of the multi-bucket federation made real:
1. Catalog migration (POST /catalog/migrate-buckets)
- One-shot normalizer for ObjectRef.bucket field
- Empty -> "primary"; legacy "data"/"local" -> "primary"
- Idempotent; re-running on canonical state is no-op
- Ran on existing catalog: 12 refs renamed from "data", 2 already
"primary", all 14 now canonical
2. X-Lakehouse-Bucket header middleware on ingest
- resolve_bucket() helper extracts header, returns
(bucket_name, store) or 404 with valid bucket list
- ingest_file and ingest_db_stream now route writes per-request
- Defaults to "primary" when header absent
- pipeline::ingest_file_to_bucket records the actual bucket on the
ObjectRef so catalog stays the source of truth for "where does this
data live"
- Verified: ingest with X-Lakehouse-Bucket: testing lands in
data/_testing/, ingest without header lands in data/, bad header
returns 404 with hint
3. queryd registers every bucket with DataFusion
- QueryEngine now holds Arc<BucketRegistry> instead of single store
- build_context iterates all buckets, registers each as a separate
ObjectStore under URL scheme "lakehouse-{bucket}://"
- ListingTable URLs include the per-object bucket scheme so
DataFusion routes scans automatically based on ObjectRef.bucket
- Profile bucket names like "profile:user" sanitized to
"lakehouse-profile-user" since URL host segments can't contain ":"
- Tolerant of duplicate manifest entries (pre-existing
pipeline::ingest_file behavior creates a fresh dataset id per
ingest); duplicates skipped with debug log
- Backward compat: legacy "lakehouse://data/" URL still registered
pointing at primary
Success gate: cross-bucket CROSS JOIN
SELECT p.name, p.role, a.species
FROM people_test p (bucket: testing)
CROSS JOIN animals a (bucket: primary)
LIMIT 5
returns rows correctly. DataFusion routed each scan to its bucket's
ObjectStore based on the URL scheme.
No regressions: SELECT COUNT(*) FROM candidates still returns 100000
from the primary bucket.
Deferred to Phase 17:
- POST /profile/{user}/activate (HNSW hot-load on profile switch)
- vectord storage paths becoming bucket-scoped (trial journals,
eval sets per-profile)

Implements the llms3.com-inspired pattern: embeddings refresh
asynchronously, decoupled from transactional row writes. New rows arrive,
ingest marks the vector index stale, a later refresh embeds only the
delta (doc_ids not already in the index).
Schema additions (DatasetManifest):
- last_embedded_at: Option<DateTime> - when the index was last refreshed
- embedding_stale_since: Option<DateTime> - set when data written, cleared on refresh
- embedding_refresh_policy: Option<RefreshPolicy> - Manual | OnAppend | Scheduled
Ingest paths (pipeline::ingest_file + pg_stream) call
registry.mark_embeddings_stale after writing. No-op if the dataset has
never been embedded — stale semantics only kick in once last_embedded_at
is set.
Refresh pipeline (vectord::refresh::refresh_index):
- Reads the dataset Parquet, extracts (doc_id, text) pairs
- Accepts Utf8 / Int32 / Int64 id columns (covers both CSV and pg schemas)
- Loads existing embeddings via EmbeddingCache (empty on first-time build)
- Filters to rows whose doc_id is NOT in the existing set
- Chunks (chunker::chunk_column), embeds via Ollama (batches of 32),
writes combined index, clears stale flag
Endpoints:
- POST /vectors/refresh/{dataset_name} - body {index_name, id_column,
text_column, chunk_size?, overlap?}
- GET /vectors/stale - lists datasets whose embedding_stale_since is set
End-to-end verified on threat_intel (knowledge_base.threat_intel):
- Initial refresh: 20 rows -> 20 chunks -> embedded in 2.1s,
last_embedded_at set
- Idempotent second refresh: 0 new docs -> 1.8ms (pure delta check)
- Re-ingest to 54 rows: mark_embeddings_stale fires -> stale_since set
- /vectors/stale surfaces threat_intel with timestamps + policy
- Delta refresh: 34 new docs embedded in 970ms (6x faster than full
re-embed); stale_cleared = true
Not in MVP scope:
- UPDATE semantics (same doc_id, different content) - would need
per-row content hashing
- OnAppend policy auto-trigger - just declares intent; actual scheduler
deferred
- Scheduler runtime - the Scheduled(cron) variant declares the intent so
operators can see which datasets expect what, but the cron itself is
separate
Per ADR-019: when a profile switches to vector_backend=Lance, this
refresh path benefits — Lance's native append replaces our "read all +
rewrite" Parquet rebuild pattern. Current MVP works well enough at
~500-5K rows to validate the architecture; Lance unblocks the 5M+ case.

- journald crate: immutable event log for every data mutation
- Events: entity_type, entity_id, field, action, old_value, new_value,
actor, source, workspace_id, timestamp
- In-memory buffer with configurable flush threshold (default 100 events)
- Flush writes events as Parquet to journal/ directory
- Query: GET /journal/history/{entity_id} — full history of any record
- Query: GET /journal/recent?limit=50 — latest events across all entities
- Convenience methods: record_insert, record_update, record_ingest
- Stats: GET /journal/stats — buffer size, persisted file count
- Manual flush: POST /journal/flush
- Per ADR-012: events are never modified or deleted
This is the single most important future-proofing decision.
Once history is lost, it's gone forever.
