dbe00d018f Federation foundation + HNSW trial system + Postgres streaming + PRD reframe 
Four shipped features and a PRD realignment, all measured end-to-end:

HNSW trial system (Phase 15 horizon item → complete)
- vectord: EmbeddingCache, harness (eval sets + brute-force ground truth),
  TrialJournal, parameterized HnswConfig on build_index_with_config
- /vectors/hnsw/trial, /hnsw/trials/{idx}, /hnsw/trials/{idx}/best,
  /hnsw/evals/{name}/autogen, /hnsw/cache/stats
- Measured on resumes_100k_v2 (100K × 768d): brute-force 44ms -> HNSW 873us
  at 100% recall@10. ec=80 es=30 locked as HnswConfig::default()
- Lower ec values trade recall for build time: 20/30 = 0.96 recall in 8s,
  80/30 = 1.00 recall in 230s

Catalog manifest repair
- catalogd: resync_from_parquet reads parquet footers to restore row_count
  and columns on drifted manifests
- POST /catalog/datasets/{name}/resync + POST /catalog/resync-missing
- All 7 staffing tables recovered to PRD-matching 2,469,278 rows

Federation foundation (ADR-017)
- shared::secrets: SecretsProvider trait + FileSecretsProvider (reads
  /etc/lakehouse/secrets.toml, enforces 0600 perms)
- storaged::registry::BucketRegistry — multi-bucket resolution with
  rescue_bucket read fallback and reachability probing
- storaged::error_journal — bucket op failures visible in one HTTP call
- storaged::append_log — write-once batched append pattern (fixes the RMW
  anti-pattern llms3.com calls out; errors and trial journals both use it)
- /storage/buckets, /storage/errors, /storage/bucket-health,
  /storage/errors/{flush,compact}
- Bucket-aware I/O at /storage/buckets/{bucket}/objects/{*key} with
  X-Lakehouse-Rescue-Used observability headers on fallback

Postgres streaming ingest
- ingestd::pg_stream: DSN parser, batched ORDER BY + LIMIT/OFFSET pagination
  into ArrowWriter, lineage redacts password
- POST /ingest/db — verified against live knowledge_base.team_runs
  (586 rows × 13 cols, 6 batches, 196ms end-to-end)

PRD realignment (2026-04-16)
- Dual use case: staffing analytics + local LLM knowledge substrate
- Removed "multi-tenancy (single-owner system)" from non-goals
- Added invariants 8-11: indexes hot-swappable, per-reader profiles,
  trials-as-data, operational failures findable in one HTTP call
- New phases 16 (hot-swap generations), 17 (model profiles + dataset
  bindings), 18 (Lance vs Parquet+sidecar evaluation)
- Known ceilings table documents the 5M vector wall and escape hatches
- ADR-017 (federation), ADR-018 (append-log pattern) added
- EXECUTION_PLAN.md sequences phases B-E with success gates and
  decision rules

8282842eaf Sync memory + phases: all 15 phases marked complete 
PHASES.md and project memory updated to reflect actual build state.
Phases 11-14 were built but trackers weren't updated.

Final stats: 11 crates, 30 tests, 16 ADRs, 2.47M rows, 100K vectors.

354c9c4a04 PRD v3: future-proofing roadmap — event journal, rich catalog, tool registry 
Phases 9-15 designed based on "future regret" analysis:
- Phase 9: Event journal (append-only mutation history — can't retrofit)
- Phase 10: Rich catalog v2 (ownership, sensitivity, lineage, freshness)
- Phase 11: Embedding versioning (model-proof vector layer)
- Phase 12: Tool registry (governed agent actions via MCP)
- Phase 13: Security & access control (field-level, row-level, audit)
- Phase 14: Schema evolution with AI migration rules
- Phase 15+: Federated query, DB connectors, OCR, fine-tuned models

8 design principles: store truth openly, describe richly, never destroy
evidence, secure centrally, expose through tools, version everything,
unstructured first-class, separate storage/compute/intelligence.

ADR-012 through ADR-016 documenting key future-proofing decisions.
Updated benchmarks: 2.47M rows, hot cache 9.8x speedup.
Updated operating rules: cheap-now/expensive-later built first.

6740a017c7 PRD v2: production roadmap with ingest, vector search, hot cache phases 
- Phase 6: Ingest pipeline (CSV/JSON → schema detect → Parquet → catalog)
- Phase 7: Vector index + RAG (embed → HNSW → semantic search → LLM answer)
- Phase 8: Hot cache + incremental updates (MemTable, delta files, merge-on-read)
- ADR-008 through ADR-011: embeddings as Parquet, delta files not Delta Lake,
  schema defaults to string, not a CRM replacement
- Staffing company reference dataset (286K rows, 7 tables)
- Honest risk assessment: vector search at scale and incremental updates are hard
