# FinData OS — STATUS (updated 2026-11-01, build session)

Legend: ✅ done and verified · 🟡 done, not yet verified in production · ⛔ blocked · ⬜ not started

# Phase 0 — Discover ✅

• ✅ Cluster/SSD inventory, node choice M3U96a with rationale (docs/DISCOVERY.md §1)
• ✅ Vendor identified (FirstRate Data), auth model, capability matrix, license summary, sanitized probes (docs/evidence/phase0-probes.md)
• ✅ Minimal authorized test requests (last_update ×7 types, ticker listings, one 15.8 MB daily 1-min archive, splits/dividends, fundamentals JSON)
• ✅ Capacity model and disk budget (≤ 250 GB curated, 60 GB hard stop)

# Phase 1 — Foundation

• ✅ Monorepo (uv workspace, 8 packages), migrations (findata migrate), secrets in .env only, redaction filter
• ✅ Authentication: owner password (argon2) + TOTP MFA, sessions, CSRF, scoped API keys; tests green
• 🟡 Deployment via mld to M3U96a, TLS via MacLustr Tunnel, health checks — see "Production" below
• ✅ CI-equivalent: make test (37 tests), make lint (ruff clean), pip-audit (no known vulnerabilities, 2026-11-01)

# Phase 2 — Market pipeline (US stocks, 1-minute)

• ✅ Connector (discover/capabilities/fetch_range/normalize/validate/checkpoint), immutable raw archives, delta Parquet per session, atomic versioned publication, supersede without duplicates (tested), 5-minute derivation (tested vs manual aggregation and DST), coverage + quality anomalies
• 🟡 Real incremental run on the node (see Production)

# Phase 3 — Fundamentals

• ✅ FirstRate fundamentals connector (verified live on AAPL during discovery), long-format PIT facts, available_at policy, revision/restatement tracking, as-of query hides later filings and later-observed restatements (tested), earnings events
• ⬜ SEC EDGAR connector: parsing implemented + fixture-tested; pending configuration (SEC_EDGAR_USER_AGENT)
• ⚠️ Limitation: vendor gives no revision history → restatements before first ingestion are unknown

# Phase 4 — Platform

• ✅ REST API /api/v1 (38+ routes, OpenAPI), cursor pagination, Arrow/CSV/JSON, async Parquet exports, sandboxed SQL, coverage/quality/health/admin, Prometheus metrics
• ✅ Python SDK (bars via Arrow pages, exports, fundamentals, SQL) — tested against a live uvicorn thread
• 🟡 Web console (Next.js static export) — built by a sub-agent; see Production for verification

# Phase 5 — Scale

• 🟡 Representative multi-year backfill (bounded letter range) — to run on the node
• 🟡 Backup + restore drill — to run on the node
• ⬜ Load benchmark

# Phase 6 — AI and polish

• ✅ Assistant endpoint implemented (Anthropic SDK, model proposes SQL only; FinData validates/executes/cites versions) — pending configuration until ANTHROPIC_API_KEY is set and a capability/cost test is recorded here; OpenAI provider not implemented
• ⬜ Security review pass on production

# Production evidence (2026-11-01, all outputs real)

Deployment: mld deploy findata --node M3U96a → PM2 findata-api (0.0.0.0:8600 behind a source-network guard) + findata-worker; Caddy route https://findata.spboucher.ai → 10.67.0.10:8600; node dir adopted as git clone (mld adopt, HEAD = origin/main). Public checks: /api/v1/health 200, console / 200, /login/ 200, /api/docs 200; headers HSTS, CSP default-src 'self', X-Frame-Options: DENY, X-Request-ID. Gotcha fixed during deploy: the API must not bind 127.0.0.1 only (Caddy reaches the node over WireGuard), and --proxy-headers must be off so the guard sees the transport peer (X-Forwarded-For is read only when the peer is the 10.67.0.1 gateway).

Owner login: created (findata create-owner), credentials in the laptop secrets folder; POST /auth/login 200 → /auth/me owner; wrong password 401; POST without CSRF 403; logout 200. TOTP not yet enrolled (owner action in Settings).

Console (headless Chromium against production): redirect to /login/, login, Overview rendered at 375 px (scrollWidth 375, no overflow) and 1280 px dark; 0 console/page errors; license banner present; Bars and Datasets pages render (datasets show unsupported/pending_configuration statuses).

Real ingestion runs (worker logs / job results)

Lake: 506.9 GB free, curated 0.54 GB, raw 0.02 GB (full Z archive deleted after publication, sha256 kept).

SDK against production (findata_sdk, API key scoped read:market/read:fundamentals/query/export): health ok (SMART Verified, worker running); AAPL 1m 900 rows (first bar 08:00Z = 04:00 ET open, close 351.6499) in 0.30 s; 5m 192 rows with volume conserved; split_div adjustment applied at query time; fundamentals as_of 2025-01-01 → 156 rows, 536 hidden (latest period 2024-09-28 filed 2024-11-01) vs now → period 2026-06-27; SQL top-volume query 0.08 s; export of 5 symbols → Parquet 4 508 rows / 99 KB in 1.15 s.

Load benchmark (laptop → public URL over the tunnel)

# Final checks (2026-11-01 evening, real outputs)

• Derived 5m compaction: the invariant check caught a real defect — the first backfill-driven derivation had written a Z-only delta for 2026-10-30 next to the full-market delta (94 duplicate (instrument, ts) for ticker Z). The compaction job refused to publish (compaction invariant violated), the duplicated file was retired by a versioned publish (v3, note recorded), derive was fixed to write per-symbol base files for backfills, and the compaction then succeeded: 6 747 delta files → 6 935 base files, 7 470 593 rows, 198 MB, 29 s (v4). No duplicates reached readers at any version.
• Backup #2 (after the backfill): pg_dump 5.9 MB zstd; rsync 14 627 files / 567.7 MB to M4M64a:~/backups/findata; remote curated file count 7 236 = local 7 236 → verified: true; 6.8 s.
• Restore drill (findata restore-drill): latest dump restored into a scratch database (472 live lake_files rows for the 1m dataset), dataset market_bars.stock.1m.raw copied back from M4M64a, 472/472 Parquet files SHA-256-verified against manifest v58, 0 missing, scratch database dropped. Measured RTO for metadata + one dataset: < 2 min on LAN.
• Quality report (1m): 26 152 471 bars, 6 521 symbols, 111 956 symbol-sessions, 2000-01-04 → 2026-10-30; anomalies (30 d): price_jump 1 480 (warning), outside_session 130 (warning); mean regular-hours completeness 0.58 (honest: many micro-caps trade a fraction of the 391 regular minutes; vendor omits zero-volume bars).
• Storage: curated 653 MB (1m 331.5 MB in 472 files; 5m 198 MB in 6 935 files), raw 17 MB (incremental archives kept; the 258 MB full Z archive deleted after publication, sha256 kept), _retired 209 MB (GC after 7 days), manifests 7.4 MB. Free 506.5 GB.
• Security scan on the node: vendor id absent from PM2 logs, PM2 dump, app directory (except .env 600), lake manifests/raw names, and Postgres (raw_archives, jobs, audit, checkpoints); API listens *:8600 behind the source guard, Postgres loopback only; session cookie HttpOnly; Secure; SameSite=strict; Max-Age=43200. A restore-drill traceback had echoed the DB password to the operator terminal → fixed (credentials via environment, redacted errors) and the Postgres password was rotated (.env on node + laptop secrets copy).
• Dependency audit: pip-audit on the exported lock → no known vulnerabilities (2026-11-01).

# Acceptance tests

# Known limitations / exact next steps

1. TOTP: enrol the owner's authenticator in Settings → Security (one click + code). Until then login is password-only.
2. Coverage: production holds one full-market session (2026-10-30) + full history for the 57 Z tickers. Extend with findata ingest backfill <letters> (≈ 258 MB zip and 67 s per small letter; large letters such as A/S take several GB and tens of minutes; budget guard stops below 60 GB free). Daily incremental runs automatically from 02:00 ET.
3. Fundamentals universe: 5 tickers loaded; set tracked tickers in Settings (or findata ingest fundamentals T1,T2,…); the 05:00 ET job currently ingests the first 50 active stocks unless tracked tickers are configured (wire fundamentals_tracked_tickers into the scheduler — small follow-up).
4. SEC EDGAR: set SEC_EDGAR_USER_AGENT="Name email" in .env to activate the independent source (parser + PIT already implemented and tested).
5. AI assistant: set ANTHROPIC_API_KEY (server-side) then run a capability/cost test (POST /api/v1/assistant, 5–10 questions) and record tokens/latency here before enabling for research use; OpenAI not implemented.
6. Bars endpoint latency on multi-year base files (≈1.5 s for a 31-day 1m window): acceptable now; if needed, add month-level partitioning or a symbol/year row-group index.
7. Encryption at rest: FileVault is off by cluster policy (unattended reboots); enable on M3U96a + M4M64a if required.
8. Fundamentals revision history before first ingestion is unknowable from the vendor; EDGAR filing-level history fixes this once configured.
9. Daily scheduler, weekly compaction and backups are in place; verify the first automatic cycle on 2026-11-03 (Monday) in Ingestion → jobs.
