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 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
