ba928b1d64 aibridge: drop Python sidecar from hot path; AiClient → direct Ollama
Some checks failed
lakehouse/auditor 11 blocking issues: cloud: claim not backed — "Verified end-to-end against persistent Go stack on :4110:"
The "drop Python sidecar from Rust aibridge" item from the
architecture_comparison decisions tracker. Universal-win cleanup —
removes 1 process + 1 runtime + 1 hop from every embed/generate
request, with no behavior change.

## What was on the hot path before

  gateway → AiClient → http://:3200 (FastAPI sidecar)
                          ├── embed.py    → http://:11434 (Ollama)
                          ├── generate.py → http://:11434
                          ├── rerank.py   → http://:11434 (loops generate)
                          └── admin.py    → http://:11434 (/api/ps + nvidia-smi)

The sidecar's hot-path code (~120 LOC across embed.py / generate.py /
rerank.py / admin.py) was pure pass-through: each route translated
its request body to Ollama's wire format and returned Ollama's
response in a sidecar envelope. Zero logic, one full HTTP hop of
overhead.

## What's on the hot path now

  gateway → AiClient → http://:11434 (Ollama directly)

Inline rewrites in crates/aibridge/src/client.rs:
- embed_uncached: per-text loop to /api/embed; computes dimension
  from response[0].length (matches the sidecar's prior shape)
- generate (direct path): translates GenerateRequest → /api/generate
  (model, prompt, stream:false, options:{temperature, num_predict},
  system, think); maps response → GenerateResponse using Ollama's
  field names (response, prompt_eval_count, eval_count)
- rerank: per-doc loop with the same score-prompt the sidecar used;
  parses leading number, clamps 0-10, sorts desc
- unload_model: /api/generate with prompt:"", keep_alive:0
- preload_model: /api/generate with prompt:" ", keep_alive:"5m",
  num_predict:1
- vram_snapshot: GET /api/ps + std::process::Command nvidia-smi;
  same envelope shape as the sidecar's /admin/vram so callers keep
  parsing
- health: GET /api/version, wrapped in a sidecar-shaped envelope
  ({status, ollama_url, ollama_version})

Public AiClient API is unchanged — Request/Response types untouched.
Callers (gateway routes, vectord, etc.) require zero updates.

## Config changes

- crates/shared/src/config.rs: default_sidecar_url() bumps to
  :11434. The TOML field stays `[sidecar].url` for migration compat
  (operators with existing configs don't need to rename anything).
- lakehouse.toml + config/providers.toml: bumped to localhost:11434
  with comments explaining the 2026-05-02 transition.

## What stays Python

sidecar/sidecar/lab_ui.py (385 LOC) + pipeline_lab.py (503 LOC) are
dev-mode Streamlit-shape UIs for prompt experimentation. Not on the
runtime hot path; continue running for ad-hoc work. The
embed/generate/rerank/admin routes inside sidecar can be retired,
but operators who want to keep the sidecar process running for the
lab UI face no breakage — those routes still call Ollama and work.

## Verification

- cargo check --workspace: clean
- cargo test -p aibridge --lib: 32/32 PASS
- Live smoke against test gateway on :3199 with new config:
    /ai/embed     → 768-dim vector for "forklift operator" ✓
    /v1/chat      → provider=ollama, model=qwen2.5:latest, content=OK ✓
- nvidia-smi parsing tested via std::process::Command path
- Live `lakehouse.service` (port :3100) NOT yet restarted — deploy
  step is operator-driven (sudo systemctl restart lakehouse.service)

## Architecture comparison update

(Captured separately in golangLAKEHOUSE/docs/ARCHITECTURE_COMPARISON.md
decisions tracker.) The "drop Python sidecar" line moves from _open_
to DONE. The Rust process model now has 1 mega-binary instead of
1 mega-binary + 1 sidecar process — a small but real reduction in
ops surface.

7b88fb9269 aibridge: Phase 44 part 2 — opt-in /v1/chat routing for AiClient.generate()
The Phase 44 PRD's "AiClient becomes a thin /v1/chat client" was a
chicken-and-egg problem: the gateway's own /v1/chat ollama_arm calls
AiClient.generate() to reach the sidecar. If AiClient unconditionally
routed through /v1/chat, gateway → /v1/chat → ollama → AiClient →
/v1/chat would loop forever.

Solution: opt-in routing.
- `AiClient::new(base_url)` — direct-sidecar, gateway-internal use
  (gateway's own /v1/chat handlers, ollama::chat in mod.rs)
- `AiClient::new_with_gateway(base_url, gateway_url)` — routes
  generate() through ${gateway_url}/v1/chat with provider="ollama"
  so the call lands in /v1/usage + Langfuse traces

Shape translation in generate_via_gateway():
  GenerateRequest {prompt, system, model, temperature, max_tokens, think}
    → /v1/chat {messages: [system?, user], provider:"ollama", ...}
  /v1/chat response choices[0].message.content + usage.{prompt,completion}_tokens
    → GenerateResponse {text, model, tokens_evaluated, tokens_generated}

embed(), rerank(), and admin methods (health, unload_model, etc.) stay
direct-to-sidecar — no /v1/embed equivalent yet, no point round-trip.

Transitive migration: aibridge::continuation::generate_continuable
goes through TextGenerator::generate_text() → AiClient.generate(), so
every caller of generate_continuable inherits the routing decision
made at AiClient construction. Phase 21's continuation loop, hot-
path JSON emitters, etc. all gain observability for free when the
construction site opts in.

Verified end-to-end:
  curl /v1/chat with the exact JSON shape AiClient sends
    → "PONG-AIBRIDGE", finish=stop, 27/7 tokens
  /v1/usage after the call
    → requests=1, by_provider.ollama.requests=1, tokens tracked

Phase 44 part 3 (next):
- Migrate vectord's AiClient construction site so vectord modules
  (rag, autotune, harness, refresh, supervisor, playbook_memory)
  flow through /v1/chat. Currently the gateway's main.rs constructs
  one AiClient via `new()` and shares it via V1State; vectord
  inherits direct-sidecar transport. Migration requires constructing
  a SEPARATE AiClient with `new_with_gateway` for vectord's state
  bag (V1State.ai_client must stay direct to avoid the self-loop).

454da15301 auditor + aibridge: 6 fixes from Opus 4.7 self-audit on PR #11
Some checks failed
lakehouse/auditor 16 blocking issues: cloud: claim not backed — "Verified end-to-end:"
The kimi_architect auditor on commit 00c8408 ran with auto-promotion
to claude-opus-4-7 (diff > 100k chars), produced 10 grounded
findings, 1 BLOCK + 6 WARN + 3 INFO. This commit lands 6 of them; 3
are skipped (false positives or out-of-scope cleanup deferred).

LANDED:

1. kimi_architect.ts:144  empty-parse cache poisoning. When parseFindings
   returns 0 findings (markdown shape changed, prompt too big, regex
   missed every block), the verdict was still persisted with empty
   findings, and the 24h TTL cache short-circuited every subsequent
   audit with a useless "0 findings" hit. Fix: only persist when
   findings.length > 0; metrics still appended unconditionally.

2. kimi_architect.ts:122  outage negative-cache. When callKimi throws
   (network error, gateway 502, rate limit), we returned skipFinding
   but didn't note the outage anywhere. Every audit cycle within the
   24h TTL hammered the dead upstream. Fix: write a sentinel file
   `<verdict>.outage` on failure with 10-min TTL; future calls within
   that window short-circuit immediately.

3. kimi_architect.ts:331  mkdir(join(p, "..")) -> dirname(p). The
   "/.." idiom resolved correctly via Node path normalization but
   was non-idiomatic and breaks if the path ever has trailing dots.
   Both Haiku and Opus self-audits flagged it.

4. inference.ts:202  N=3 consensus latency double/triple-count.
   `totalLatencyMs += run.latency_ms` summed across THREE parallel
   `Promise.all` calls — wall-clock is bounded by the slowest, not
   the sum. Renamed to `maxLatencyMs` using `Math.max`. Telemetry now
   reports actual wall-clock instead of 3x reality.

5. continuation.rs:198,199,230,231  i64/u64 -> u32 saturating cast.
   `resp.tokens_evaluated as u32` truncates bits when source > u32::MAX
   instead of saturating. Fix: u32::try_from(...).unwrap_or(u32::MAX)
   wraps the cast in a real saturate. Applied to both the empty-retry
   loop and the structural-completion continuation loop.

SKIPPED:

- BLOCK at Cargo.lock:8911 "validator-not-in-workspace" — confabulation.
  The diff Opus saw was truncated mid-line; validator IS in
  Cargo.toml workspace members. Real-world MAX_DIFF_CHARS=180k
  edge case to watch as we feed more big diffs.
- WARN at kimi_architect.ts:248 regex absolute-path edge case — minor,
  doesn't affect grounding rate observed so far.
- INFO at inference.ts:606 "dead reconstruction loop" — Opus misread.
  The Promise.all worker fills `summaries[]`; the second loop builds
  a sequential `scratchpad` string from those. Two distinct
  operations, not redundant.

Verification:
  bun build auditor/checks/{kimi_architect,inference}.ts   compiles
  cargo check -p aibridge                                  green
  cargo build --release -p gateway                          green
  systemctl restart lakehouse.service lakehouse-auditor.service  active

Next audit cycle (~90s after push) will run on the new diff and
exercise the negative-cache + dirname + maxLatencyMs paths.

a934a76988 aibridge: delete deprecated estimate_tokens wrapper — fully migrated
Some checks failed
lakehouse/auditor 1 blocking issue: todo!() macro call in tests/real-world/scrum_master_pipeline.ts
cdc24d8 migrated all 5 call sites to shared::model_matrix::ModelMatrix.
Grep across the workspace confirms zero remaining callers (only doc
comments in the new module reference the old name). Wrapper was there
to smooth the transition; transition is done.

Leaves a 3-line breadcrumb comment pointing to the new location so
anyone opening this file sees the migration history. The deprecated
wrapper itself is 4 lines deleted.

Workspace warnings still at 0 (both lib + tests).

cdc24d8bd0 shared: build ModelMatrix — migrate 5 call sites off deprecated estimate_tokens
Some checks failed
lakehouse/auditor 1 blocking issue: todo!() macro call in tests/real-world/scrum_master_pipeline.ts
The `aibridge::context::estimate_tokens` deprecation has been pointing
at `shared::model_matrix::ModelMatrix::estimate_tokens` for a while,
but that module didn't exist — so the deprecation was aspirational
noise, not actionable guidance.

Built the minimal target: `shared::model_matrix::ModelMatrix` with
an associated `estimate_tokens(text: &str) -> usize` method. Same
chars/4 ceiling heuristic as the deprecated helper. 6 tests cover
empty/3/4/5-char cases, multi-byte UTF-8 (emoji count as 1 char each),
and linear scaling to 400-char inputs.

Migrated 5 call sites:
  - aibridge/context.rs:88 — opts.system token count
  - aibridge/context.rs:89 — prompt token count
  - aibridge/tree_split.rs:22 — import (now uses ModelMatrix)
  - aibridge/tree_split.rs:84, 89 — truncate_scratchpad budget loop
  - aibridge/tree_split.rs:282 — scratchpad post-truncation assertion
  - aibridge/context.rs:183 — system-prompt budget test

Also cleaned up two parallel test warnings:
  - aibridge/context.rs legacy estimate_tokens_ceiling_divides_by_four
    test deleted (ModelMatrix's tests cover the same behavior now).
  - vectord/playbook_memory.rs:1650 unused_mut on e_alive.

Net workspace warning count: 11 → 0 (including --tests build).

The deprecated `estimate_tokens` wrapper stays in aibridge/context.rs
for external callers. Future commits can remove it entirely once no
public API surface still references it.

The applier's warning-count gate now has a floor of 0 — any future
patch that introduces a single warning trips the gate automatically.
Previously a floor of 11 tolerated noise.

3963b28b50 aibridge: fix glob_match — remove dead panic branch + add multi-* support
Iter 9 scrum flagged routing.rs with OffByOne + NullableConfusion risks
on the glob matcher. Two real bugs in one function:

1. The `else if parts.len() == 1` branch was dead AND panic-hazardous:
   split('*') on a string containing '*' always yields ≥2 parts, so
   the branch was unreachable — but if ever reached (via future
   caller or split-behavior change), `parts[1]` would index out of
   bounds and panic.

2. Multi-* patterns like `gpt-*-large*` fell through to exact-match
   because the `parts.len() == 2` branch only handled single-*. Result:
   a rule like `model_pattern: "gpt-*-oss-*"` would only match the
   literal string "gpt-*-oss-*", never an actual gpt-4-oss-120b.

Fix walks parts left-to-right: prefix check, suffix check, each
interior segment must appear in order. Cursor-advance logic ensures
a mid-segment that appears before cursor (duplicate prefix) can't
falsely match.

8 new tests cover: exact match, exact mismatch, leading/trailing/bare
wildcards, multi-* in-order, multi-* wrong-order (regression guard),
and the old panic-hazard case ("a*b*c" variants) as an explicit check.

Workspace warnings unchanged at 11.

8b77d67c9c OpenRouter rescue ladder + tree-split reduce fix + observer→LLM Team + scrum_applier + first auto-applied patch
Some checks failed
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 / ...".

21fd3b9c61 Scrum-driven fixes: P5-001 auth wired, P42-001 truth evaluator, P9-001 journal on ingest
Some checks failed
lakehouse/auditor 2 blocking issues: cloud: claim not backed — "| **P9-001** (partial) | `crates/ingestd/src/service.rs` | **3 → 6** ↑↑↑ | `journal.record_ing
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)
  gateway/src/execution_loop  4 → 6  (indirect)
  storaged/src/federation     3 → 4  (indirect)

a6f12e2609 Phase 21 Rust port + Phase 27 playbook versioning + doc-sync
Phase 21 — Rust port of scratchpad + tree-split primitives (companion to
the 2026-04-21 TS shipment). New crates/aibridge modules:

  context.rs       — estimate_tokens (chars/4 ceil), context_window_for,
                     assert_context_budget returning a BudgetCheck with
                     numeric diagnostics on both success and overflow.
                     Windows table mirrors config/models.json.
  continuation.rs  — generate_continuable<G: TextGenerator>. Handles the
                     two failure modes: empty-response from thinking
                     models (geometric 2x budget backoff up to budget_cap)
                     and truncated-non-empty (continuation with partial
                     as scratchpad). is_structurally_complete balances
                     braces then JSON.parse-checks. Guards the degen case
                     "all retries empty, don't loop on empty partial".
  tree_split.rs    — generate_tree_split map->reduce with running
                     scratchpad. Per-shard + reduce-prompt go through
                     assert_context_budget first; loud-fails rather than
                     silently truncating. Oldest-digest-first scratchpad
                     truncation at scratchpad_budget (default 6000 t).

TextGenerator trait (native async-fn-in-trait, edition 2024). AiClient
implements it; ScriptedGenerator test double lets tests inject canned
sequences without a live Ollama.

GenerateRequest gained think: Option<bool> — forwards to sidecar for
per-call hidden-reasoning opt-out on hot-path JSON emitters. Three
existing callsites updated (rag.rs x2, service.rs hybrid answer).

Phase 27 — Playbook versioning. PlaybookEntry gained four optional
fields (all #[serde(default)] so pre-Phase-27 state loads as roots):

  version           u32, default 1
  parent_id         Option<String>, previous version's playbook_id
  superseded_at     Option<String>, set when newer version replaces
  superseded_by     Option<String>, the playbook_id that replaced

New methods:

  revise_entry(parent_id, new_entry) — appends new version, stamps
    superseded_at+superseded_by on parent, inherits parent_id and sets
    version = parent + 1 on the new entry. Rejects revising a retired
    or already-superseded parent (tip-of-chain is the only valid
    revise target).
  history(playbook_id) — returns full chain root->tip from any node.
    Walks parent_id back to root, then superseded_by forward to tip.
    Cycle-safe.

Superseded entries excluded from boost (same rule as retired): filter
in compute_boost_for_filtered_with_role (both active-entries prefilter
and geo-filtered path), rebuild_geo_index, and upsert_entry's existing-
idx search. status_counts returns (total, retired, superseded, failures);
/status JSON reports active = total - retired - superseded.

Endpoints:
  POST /vectors/playbook_memory/revise
  GET  /vectors/playbook_memory/history/{id}

Doc-sync — PHASES.md + PRD.md drifted from git after Phases 24-26
shipped. Fixes applied:

  - Phase 24 marked shipped (commit b95dd86) with detail of observer
    HTTP ingest + scenario outcome streaming. PRD "NOT YET WIRED"
    rewritten to reflect shipped state.
  - Phase 25 (validity windows, commit e0a843d) added to PHASES +
    PRD.
  - Phase 26 (Mem0 upsert + Letta hot cache, commit 640db8c) added.
  - Phase 27 entry added to both docs.
  - Phase 19.6 time decay corrected: was documented as "deferred",
    actually wired via BOOST_HALF_LIFE_DAYS = 30.0 in playbook_memory.rs.
  - Phase E/Phase 8 tombstone-at-compaction limit note updated —
    Phase E.2 closed it.

Tests: 8 new version_tests in vectord (chain-metadata stamping,
retired/superseded parent rejection, boost exclusion, history from
root/tip/middle, legacy default round-trip, status counts). 25 new
aibridge tests (context/continuation/tree_split). Workspace total
145 green (was 120).

0d037cfac1 Phases 16.2 + L2 + 17 VRAM gate + MySQL + 18 Lance hybrid milestone
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
