+# Auditor Context — project preamble for fact extraction
+
+This file is read by `auditor/fact_extractor.ts` and prepended to the
+extract-facts prompt sent to llm_team. The goal: give the extractor +
+verifier enough grounding to ground domain-specific facts instead of
+marking them UNVERIFIABLE by default.
+
+Keep this short (< 400 words). Verifier only reads the first ~4KB of
+the prompt alongside the facts. Longer = noise, not signal.
+
+Update when: a new Phase lands, a crate is added/removed, the project's
+primary domain shifts (e.g. staffing → DevOps).
+
+---
+
+## What Lakehouse is
+
+Lakehouse is a Rust-first data platform over S3-compatible object
+storage. Primary use: a staffing company ingesting legacy CRM data for
+AI-powered worker matching, contract fulfillment, and playbook-driven
+coordination.
+
+Architecture: 13 Rust crates + a Python sidecar (Ollama) + TypeScript
+sub-agents (auditor, scrum_master, bot). Runs on a single server
+(Nvidia A4000, 128GB RAM). All services on localhost: gateway :3100,
+sidecar :3200, UI :3300, MCP :3700, observer :3800, MinIO :9000.
+
+## Key crates (each maps to a responsibility)
+
+- **shared** — types, Arrow helpers, PII utilities, SecretsProvider
+- **proto** — gRPC definitions
+- **storaged** — S3/MinIO I/O, AppendLog, ErrorJournal
+- **catalogd** — metadata authority (manifests, views, tombstones)
+- **queryd** — DataFusion SQL, MemTable cache, compaction
+- **ingestd** — CSV/JSON/PDF/Postgres/MySQL ingest
+- **vectord** — embeddings, HNSW index, **playbook_memory meta-index** (Phase 19+)
+- **vectord-lance** — Lance 4.0 firewall crate (separate Arrow version)
+- **journald** — append-only mutation event log
+- **aibridge** — Rust↔Python sidecar bridge, context budget + continuation
+- **gateway** — Axum HTTP :3100 + gRPC :3101 (Phase 38+ adds /v1/chat)
+- **ui** — Dioxus WASM (stale, pre-Phase-9)
+- **lance-bench** — standalone benchmark
+
+## Current architectural direction (Phase 38-44)
+
+Universal AI Control Plane: a `/v1/chat` OpenAI-compatible API that
+routes all LLM traffic through one layer for token accounting + provider
+fallback. Truth Layer + Validation Pipeline enforce staffing-domain
+invariants (worker eligibility, PII, contract rules). The Auditor
+(Phase A of cohesion plan) hard-blocks PR merges on placeholder code.
+
+## Auditor sub-agent role
+
+`auditor/` (TypeScript, Bun runtime) polls Gitea every 90s for open PRs.
+For each fresh head SHA it runs 4 checks in parallel: static (grep-style
+placeholder detection), dynamic (runs the hybrid fixture), inference
+(gpt-oss:120b cloud review with N=3 consensus + qwen3-coder:480b
+tie-breaker), and kb_query (reads `data/_kb/*.jsonl` for prior evidence).
+Verdicts post to Gitea as commit status + review comment. Findings
+append to `data/_kb/audit_lessons.jsonl` (path-agnostic signatures for
+dedup). Curated scratchpads from tree-split get routed through this
+extract-facts pipeline to populate `audit_facts.jsonl` — which is what
+you (the extractor) are currently producing.
+
+## Things that are NOT the auditor
+
+- The LLM Team UI at `/root/llm_team_ui.py` (devop.live:5000) — a separate product for human-facing multi-model experimentation
+- The scrum_master pipeline at `tests/real-world/scrum_master_pipeline.ts` — reviews files, not claims
+- The bot at `bot/` — will apply fixes, doesn't audit

   - Mem0-style upsert: `/seed` with `append=true` (default) routes through `upsert_entry`, which decides ADD / UPDATE / NOOP on (operation, day, city, state). Same-day re-seed merges names (union, stable order) instead of duplicating the row. Identical re-seed is a no-op. Different-day same-operation is a fresh ADD. Playbook_id stays stable on UPDATE so prior citations remain valid.
   - Letta-style hot cache: `PlaybookMemory` now holds a `geo_index: HashMap<(city_lower, state_upper), Vec<entry_idx>>` rebuilt on every mutation. Geo-filtered boost queries skip the full scan and hit the O(1) key lookup. At 1.9K entries the full scan was sub-ms; the index scales the same path to 100K+ without code changes.
   - `UpsertOutcome` enum reported back to callers — `{mode: added|updated|noop, playbook_id, merged_names?}` + `entries_after`.
+- [x] **Phase 37: Hot-swap async** (2026-04-22)
+  - Extended `JobTracker` with `JobType::ProfileActivation` + `Embed` enum variants
+  - Made `activate_profile` return immediately with `job_id`, work runs in background via `tokio::spawn`
+  - Background jobs tracked via `POST /vectors/jobs/{id}` + `GET /vectors/jobs`
+- [x] **Phase 38: Universal API Skeleton** (2026-04-23)
+  - `/v1/chat` — OpenAI-compatible POST, forwards to local Ollama or Ollama Cloud
+  - `/v1/usage` — returns `{requests, prompt_tokens, completion_tokens, total_tokens}`
+  - `/v1/sessions` — returns `{data: [], note: "Phase 38: stateless"}`

+- [x] **Phase 39: Provider Adapter Refactor** (2026-04-23)
+  - `ProviderAdapter` trait with `chat()` + `embed()` + `unload()` + `health()`
+  - `OllamaAdapter` — wraps existing AiClient
+  - `OpenRouterAdapter` — HTTP client to openrouter.ai
+  - `provider_key()` routing by model prefix (openrouter/* → OpenRouter)
