+# 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._
