- AccessControl: agent roles with allowed sensitivity levels
- 4 default roles: admin (all), recruiter (PII ok), analyst (financial ok), agent (internal only)
- Field-level masking: determines which columns to mask per agent based on sensitivity
- Query audit log: tracks every query with agent, datasets, PII fields accessed
- Endpoints: GET/POST /access/roles, GET /access/audit, POST /access/check
- Toggleable via config (auth.enabled)
- 100K embedding: supervisor now sustained 125/sec (2.9x vs single pipeline)

- 4 parallel pipelines on i9 + A4000 via Ollama
- Previous single-pipeline: 43/sec, 39min for 100K
- Supervisor: 67.6/sec, 22min for 100K
- Previous 100K attempt failed at 97K (no retry) — supervisor handles this
- Checkpointing every 1000 chunks for crash recovery
- Round-robin retry on batch failure (3 attempts)

- JobTracker: create/update/complete/fail jobs with progress tracking
- POST /vectors/index now returns immediately with job_id (HTTP 202)
- Embedding runs in tokio::spawn background task
- GET /vectors/jobs/{id} returns live progress (chunks embedded, rate, ETA)
- GET /vectors/jobs lists all jobs
- Progress logged every 100 batches with chunks/sec and ETA
- 100K embedding job running successfully at 44 chunks/sec
- System stays responsive during embedding (queries in 23ms)

- WorkspaceManager: create/get/list workspaces with daily/weekly/monthly/pinned tiers
- Saved searches: agent stores SQL queries in workspace context
- Shortlist: tag candidates/records to a workspace with notes
- Activity log: track calls, emails, updates per workspace per agent
- Instant handoff: transfer workspace ownership with full history
Zero data copy — just a pointer swap, receiving agent sees everything
- Persistence: workspaces stored as JSON in object storage, rebuilt on startup
- Endpoints: /workspaces/create, /{id}, /{id}/handoff, /{id}/search,
/{id}/shortlist, /{id}/activity
- Tested: Sarah creates workspace, saves searches, shortlists 3 candidates,
logs activity, hands off to Mike who continues seamlessly

- MemCache: LRU in-memory cache for hot datasets (configurable max, default 16GB)
Pin/evict/stats endpoints: POST /query/cache/pin, /cache/evict, GET /cache/stats
- Delta store: append-only delta Parquet files for row-level updates
Write deltas without rewriting base files, merge at query time
- Compaction: POST /query/compact merges deltas into base Parquet
- Query engine: checks cache first, falls back to Parquet, merges deltas
- Benchmarked on 2.47M rows:
1M row JOIN: 854ms cold → 96ms hot (8.9x speedup)
100K filter: 62ms cold → 21ms hot (3x speedup)
1.1M rows cached in 408MB RAM
