From 6e7f57c6b26ae96e15cfce61d87a4d2821218c48 Mon Sep 17 00:00:00 2001 From: Giorgio Gilestro Date: Mon, 18 May 2026 14:16:57 +0100 Subject: [PATCH 1/3] phase G: data minimisation + passwordless auth + DeepSeek-first LLM Server no longer holds portfolios. Holdings live in the browser (localStorage); the server publishes an anonymous ticker_universe and a gzipped /api/universe payload identical for every authenticated user, so access patterns can't betray which tickers a user holds. AI commentary is generated ephemerally from the browser-supplied pie and the cost ledger row records no positions. Migrations 0009-0011 added the universe table and dropped positions / portfolio_snapshots / portfolios. Authentication is now e-mail OTP only. Migration 0010 dropped password_hash and email_verified (every active session is by construction proof of email control). The /signup endpoint is gone; signup and login share a single email-entry page. Email rendering is HTML+plain-text multipart with a shared brand palette (app/branding.py) asserted in sync with the CSS by a drift-detection test. LLM provider defaults to DeepSeek-direct (cheaper, api.deepseek.com) with OpenRouter as automatic fallback if DeepSeek fails. ai_log_job and indicator_summary_job now iterate the two tones (NOVICE, INTERMEDIATE) per cycle so the dashboard's tone toggle is instant; PROMPT_VERSION bumped to 6 with an educational anti-TA / anti-gambling stance baked into _CORE. NOVICE mode renders a curated glossary inline (CBOE VIX, yield curve, HY OAS, etc.) with JS-positioned tooltips that survive viewport edges and sticky bars. Model name and tokens hidden from the user UI; still recorded in StrategicLog.model and AICall for admin. Layout adds a sticky top nav, a sticky bottom markets bar (one chip per exchange with status LED + headline index + 1d change), and Phase H feedback reporting is queued in tasks/todo.md.

+# Phase G — Data-minimisation refactor
+
+**Date opened:** 2026-05-16
+**Status:** Planning. No code yet — awaiting sign-off on this doc.
+
+## Goal
+
+Drop "server holds your portfolio" from the threat model. After this phase,
+Cassandra at rest knows: email, password hash, billing state, AI cost ledger,
+a non-attributed set of tickers, and current market prices for those tickers.
+It does **not** know which user holds what, at what cost, at what quantity.
+
+Holdings live in the browser (localStorage). The server acts as a price proxy
+that returns the **entire ticker universe** to every authenticated client, so
+the request itself can't betray the user's pie. AI commentary is the only path
+where holdings transit the server, and it does so **in-memory for the
+duration of one LLM call**, never persisted.
+
+## The shape
+

+
+## Privacy properties this buys
+
+1. **Holdings are not at rest**. Server never writes a row that says "user X
+   holds ticker Y". A full DB dump reveals only the *union* of all users'
+   tickers, with no attribution.
+2. **Price-refresh requests are unlinkable**. Every authenticated user gets
+   the same payload (entire universe), so access logs / breach evidence can't
+   tell holdings from request bodies.
+3. **AI analysis is ephemeral**. Holdings transit memory only during one LLM
+   call (~5-30s). No DB persistence, no logs of pie content.
+
+## Privacy properties this does NOT buy
+
+1. **Server briefly sees the pie** during `/api/portfolio/parse` (CSV upload)
+   and `/api/analyze`. This is "minutes-of-retention, in-memory" not
+   "zero-knowledge". GDPR-honest framing: *"shortest possible processing
+   window, no retention."*
+2. **Universe-add timing leak**. If only one user is active when a new
+   ticker enters the universe, that ticker is linkable to that user via
+   timestamps. Mitigation in plan below.
+3. **Email is still PII**. Paddle billing requires it; nothing to do about
+   that. Document clearly in privacy policy.
+
+## Data model changes
+
+### New tables
+
+```python
+class TickerUniverse(Base):
+    """The set of public tickers Cassandra tracks. Populated as the union
+    of all user holdings, *without user attribution*."""
+    __tablename__ = "ticker_universe"
+    yahoo_ticker: Mapped[str] = mapped_column(String(32), primary_key=True)
+    currency: Mapped[str | None] = mapped_column(String(8))
+    first_seen_at: Mapped[datetime] = mapped_column(DateTime(timezone=True), default=utcnow)
+    # Refreshed by any user heartbeat that contains this ticker.
+    # When utcnow() - last_referenced_at > UNIVERSE_EVICTION_TTL, prune.
+    last_referenced_at: Mapped[datetime] = mapped_column(DateTime(timezone=True), default=utcnow)
+```
+
+### Removed tables (migration 0009)
+
+- `positions`
+- `portfolio_snapshots`
+- `portfolios`
+
+(The `Portfolio` model concept goes away. A user "having a portfolio" is now
+purely a browser-localStorage concept.)
+
+### Kept as-is
+
+- `users`, `email_otps` — auth
+- `quotes`, `quotes_daily` — price data
+- `headlines`, `feeds` — news
+- `strategic_logs`, `indicator_summaries`, `ai_calls` — macro AI (shared)
+- `instrument_map` — T212 ↔ Yahoo resolution (admin-managed, read-only to user paths)
+
+## New API surface
+
+```
+GET /api/universe
+    Auth: session/bearer required.
+    Returns the full universe with current prices, gzipped JSON:
+      {
+        "as_of": "2026-05-16T14:00:00Z",
+        "tickers": {
+          "AAPL": {"p": 234.56, "c": "USD", "d": {"1d": 0.5, "1m": 3.2, "1y": 18.4}},
+          "VWRL.L": {...},
+          ...
+        }
+      }
+    Cache-Control: max-age=60. Browser refreshes once a minute.
+
+GET /api/universe/sparkline/{ticker}
+    Auth required. Lazy-loaded on hover. Same shape as today.
+
+POST /api/portfolio/parse
+    Auth required. multipart/form-data: file=.
+    Server: parses, resolves T212→Yahoo via instrument_map, adds resolved
+    tickers to ticker_universe (no user FK), returns parsed pie to browser.
+    Discards parsed pie before responding.
+    Response:
+      {
+        "positions": [
+          {"yahoo_ticker": "AAPL", "name": "Apple Inc",
+           "qty": 5, "avg_cost_gbp": 178.40, "currency": "USD"},

+        ],
+        "base_currency": "GBP",
+        "warnings": ["3 unmapped tickers: ..."]
+      }
+
+POST /api/analyze
+    Auth required. Body: {"positions": [...], "prices": {...}, "anchor": "..."}.
+    Server constructs prompt, calls LLM, returns commentary text.
+    No DB writes mentioning positions. ai_calls row written (no pie content).
+    Optional: cache commentary text keyed by sha256(positions canonical JSON)
+    so re-clicking is free. The hash is not reversible to holdings.
+    Response: {"content": "...", "model": "...", "generated_at": "..."}
+
+POST /api/universe/heartbeat   (optional, see "Open questions" below)
+    Browser periodically POSTs its localStorage ticker set so the server
+    can refresh last_referenced_at for those tickers. The "active client
+    bumps timestamps" pattern keeps the universe trimmed to actually-held
+    tickers.
+```
+
+### Endpoints removed
+
+- `POST /api/portfolios/upload` (Phase B) — replaced by `/api/portfolio/parse`
+- `GET /api/portfolio/{name}/summary` — gone; browser computes from
+  localStorage + universe prices
+
+## Mitigation: universe-add timing leak
+
+The naive "INSERT IGNORE on CSV parse" lets a passive observer link a
+universe-row's `first_seen_at` to a specific user's upload time. Two
+mitigations, layered:
+
+1. **Batch additions.** New tickers don't enter `ticker_universe` directly
+   from the request handler. They're queued (in Redis or in an in-process
+   buffer) and flushed at fixed 5-minute boundaries. Multiple users' uploads
+   batch together; ordering within a flush is randomised.
+2. **Padding.** On every flush, also re-touch `last_referenced_at` on N
+   random existing universe rows. This makes "row updated at flush time T"
+   not specifically informative about new tickers.
+
+At low user counts (alpha), the leak is mathematically unavoidable; document
+this in the alpha tester agreement and skip both mitigations until we have
+≥10 concurrent users.
+
+## Migration sequence
+
+- [ ] **0009_drop_portfolio_tables.py** — drop `positions`,
+      `portfolio_snapshots`, `portfolios`. Upgrade extracts distinct tickers
+      from `positions` first to seed `ticker_universe`. Downgrade is
+      one-way (irreversible drop) — document this.
+- [ ] **0010_ticker_universe.py** — create `ticker_universe` table.
+      Could be merged into 0009; keep separate for clarity.
+
+## Implementation order
+
+Strategy: build the new path alongside the existing one. The destructive
+`DROP TABLE` step lands LAST, after end-to-end verification of the new
+architecture. Old endpoints are removed only after the browser is updated.
+
+**Additive (non-destructive):**
+
+- [x] 1. Add `redis:7-alpine` service to docker-compose.yml. New env var
+        `REDIS_URL` in Settings. Smoke-test connectivity from `app`.
+- [x] 2. Migration `0009_ticker_universe.py` — creates the new table only,
+        leaves existing portfolio tables untouched.
+- [x] 3. `app/services/ticker_universe.py` — add/refresh/evict logic.
+        Batch-flush via Redis with a 5-min boundary; padding-on-flush at
+        first stays off (toggle for when we reach ≥10 users).
+- [x] 3a. **Auth flip: passwordless.** Drop password_hash + email_verified
+         (migration 0010). Collapse signup into login. Every auth is OTP.
+         Threat model after Phase G makes passwords pure liability — see
+         memory:cassandra_data_minimisation.
+- [x] 4. `app/services/portfolio_analysis.py` — ephemeral LLM prompt +
+        call. Pie passed in via request body, held in a function-local
+        variable, never written to DB or logs. Includes input sanitisation
+        (prompt-injection defence, NaN/inf rejection, 200-position cap).
+- [x] 5. New router `app/routers/universe.py` with:
+          - `GET /api/universe`
+          - `GET /api/universe/sparkline/{ticker}`
+          - `POST /api/portfolio/parse`
+          - `POST /api/analyze`
+        Added `GZipMiddleware` (≥500-byte threshold). Confirmed 70%
+        compression on a 30-ticker universe payload. Old endpoints in
+        `app/routers/api.py` stay live for now.
+- [x] 6. `app/templates/partials/portfolio.html` (panel shell) +
+        `static/js/portfolio.js` (localStorage pie + universe fetch +
+        P/L compute + analyze button). `upload.html` rewired to new
+        `/api/portfolio/parse` endpoint. CSS additions: pf-pill,
+        pf-actions, pf-analysis, pf-warn.
+- [x] 6a. Scheduler additions for Phase G:
+          - `universe_flush_job` every 5 min (flushes Redis buffer → DB)
+          - `universe_evict_job` daily at 00:15 UTC (60-day TTL prune)
+          - `market_job` extended to fetch `config TOML ∪ ticker_universe`
+- [x] 7. Tests: universe add/evict (in service), parse-shape sanitisation
+        (21 tests), unlinkability contract (structural assertion that
+        the universe handler signature can't take a user-identifying
+        parameter without failing CI).
+- [ ] 8. **End-to-end check (USER):** re-upload existing T212 CSV via
+        new path, confirm pie renders correctly from localStorage with
+        live prices, AI commentary works, no rows land in `positions` /
+        `portfolio_snapshots`.
+
+**Destructive (only after step 8 passes):**
+
+- [x] 9. Migration `0011_drop_portfolio_tables.py` — dropped
+        `positions` (299 rows), `portfolio_snapshots` (23 rows),
+        `portfolios` (2 rows). Downgrade is one-way (structural only).
+- [x] 10. Removed old endpoints `POST /api/portfolios/upload`,
+         `GET /api/portfolios`. Removed `portfolio_job.py` from
+         scheduler. `market_job` already fetches "config TOML ∪
+         ticker_universe" (step 6a). `news_job` rewired to use
+         `ticker_universe ∪ instrument_map` for per-ticker news.
+- [x] 11. Deleted `Portfolio` / `PortfolioSnapshot` / `Position` models
+         from `app/models.py`. Removed `PortfolioSummary` / `PositionOut`
+         from `app/schemas.py`. Removed `persist_pie` + `PersistResult`
+         from `csv_import.py` (parser remains).
+
+**Polish:**
+
+- [ ] 12. `/privacy` page stating exactly what's held server-side and TTLs.
+- [ ] 13. Update README + plan file's review section.
+
+## Out of scope (deferred)
+
+- **E2E encrypted sync of localStorage across devices.** Real demand from
+  paying users would justify this. Mechanism: user-derived key from
+  password (PBKDF2/Argon2 → KEK), encrypted pie blob stored on server,
+  server can't decrypt. Phase H-ish.
+- **True PIR for prices.** Cryptographic overkill for retail SaaS.
+- **Anonymous billing.** Paddle requires an email. Accepted.
+
+## Locked decisions (2026-05-16)
+
+1. **Redis**: new compose service. Stores (a) the ephemeral pie during
+   `/api/analyze` with a 5-min TTL, (b) the batch-buffer of new tickers
+   awaiting universe flush. Slots in later for rate limits and Paddle
+   webhook idempotency (Phase D).
+2. **Sparklines lazy** — never bundled in `/api/universe`. Browser fetches
+   `/api/universe/sparkline/{ticker}` on hover.
+3. **Passive aging** — no heartbeat endpoint. `last_referenced_at` is bumped
+   whenever a ticker appears in `/api/portfolio/parse` or `/api/analyze`.
+   Eviction cron prunes rows with `last_referenced_at < now - 60 days`.
+   Effect: a user who re-uploads their CSV monthly keeps their tickers
+   alive in the universe; long-departed users' tickers age out naturally.
+4. **No data migration of existing pies** — `positions` rows are dropped
+   without backfilling `ticker_universe`. Users re-upload their CSV once
+   after deploy; it lands in browser localStorage.
+
+## Review section (to be filled after implementation)
+
+_TBD after sign-off + implementation._

From: Giorgio Gilestro

Subject: [PATCH 2/3] news: auto-tag headlines + market-aware cadence + filter
 UI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Move news_job from hourly to 3x/hour (cron 10,30,50), with a CadencePolicy
  gate that throttles to active hours (07-21 UTC weekdays at 20 min), off-hours
  (3 h), weekends (6 h). Keeps the daytime feed fresh without spamming RSS
  sources overnight.
- Tag each headline on ingestion via DeepSeek (BATCH_SIZE=25, max_tokens=4000,
  json.JSONDecoder().raw_decode + per-row regex recovery for resilient parsing).
  Vocabulary: 16 tags including new EU / USA / AI / Conflict. NULL tags are
  picked up automatically on the next news_job run, so back-tagging is implicit
  rather than a separate migration step.
- Tag UI: pill bar above the feed with off → include → exclude cycle on click;
  shift-click jumps straight to exclude. State persists in localStorage and is
  injected into /api/news requests via htmx:configRequest. Per-row chips sit to
  the right of the headline (new 5-column grid: age | source | title | tags |
  UTC) so vertical density stays high.
- Strategic log header bug: model was hallucinating "(Updated 21:30 UTC)" in
  future tense. Bumped PROMPT_VERSION 6→7, added explicit ban on time-of-day
  clauses, and supply the actual current UTC time in the user prompt so the
  model has no need to invent one.

Migration 0012 adds headlines.tags (JSON, nullable). Tests cover vocabulary
integrity, validation/normalisation, and the JSON-recovery parser (17 tests).

Subject: [PATCH 3/3] phase D milestones 1+2: referral system + paid-access
 gate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Lays the billing-prep spine before Paddle lands in D.3.

D.1 — referrals
- users.referral_code: unique 8-char URL-safe code (alphabet excludes the
  ambiguous 0/O/1/I/L). Generated lazily on first /settings hit so existing
  accounts pick one up without a backfill migration.
- users.referred_by_user_id + new referrals audit table (referrer,
  referred, created_at, converted_at, credited_at). converted_at /
  credited_at stay null until D.3 fills them via the Paddle webhook.
- POST /login accepts ?ref=; the code rides on the signed
  pending-verify cookie so it survives the GET → POST → /verify hop.
- /settings page: email, tier badge, referral code chip + invite link
  with one-click copy, pending/converted/active-credits stats grid.
  Settings nav link added to the top bar.

Reward shape: when the referred user makes their first paid Paddle
subscription, both they and the referrer get 50% off for 3 months.
(D.3 wires the actual credit application via the Paddle webhook.)

D.2 — paid-access gate
- users.credit_until: timestamp until which a free-tier account has
  paid-tier access. Null = no credit. Populated by admin CLI now and the
  D.3 webhook later.
- app.services.access exposes paid_status(user) → PaidStatus dataclass
  (active / source / expires_at / days_remaining), is_paid_active() with
  admin-bearer-token bypass, and a require_paid FastAPI dependency that
  raises 402 Payment Required for free-tier callers.
- POST /api/analyze (portfolio AI commentary) gated behind require_paid.
- Settings page surfaces credit window when active ("free · credit · N
  day(s) remaining (expires YYYY-MM-DD)") and the upgrade hint when not.
- Admin CLI: python -m app.cli {grant-credit,revoke-credit,show-status}.
  grant-credit is idempotent — extends from max(now, current expiry) so
  re-running the command never erodes an existing grant.

Migrations 0013 (referrals) and 0014 (credit_until). Tests cover the
paid-status truth table, code generation + normalisation, CLI argument
parsing, and the pending-cookie ref roundtrip (29 new tests).

+"""referrals: user.referral_code + user.referred_by_user_id + referrals table
+
+Phase D.1 of the multi-user billing work. Adds:
+
+- `users.referral_code` — unique 8-char URL-safe code per user, generated
+  lazily on first visit to /settings (or signup).
+- `users.referred_by_user_id` — FK to the user who referred this account,
+  set at signup if `?ref=` was supplied. Null otherwise.
+- `referrals` — audit trail. One row per (referrer, referred) pair when the
+  link is captured. `converted_at` / `credited_at` filled in D.3 by the
+  Paddle webhook when the referred user makes their first paid subscription.
+
+The Credit table that holds actual discount records is deferred to D.3 —
+no point creating it until Paddle is wired and we know what to write.
