410afe0078 stripe: wire checkout, customer portal, and webhook for read.markets
Stripe is the merchant-on-record for read.markets after Polar/Paddle
both declined the financial-media category. This commit lands the
full subscription flow: an "Upgrade" button on /pricing now opens a
real Stripe-hosted Checkout, completes the subscription, and the
webhook flips user.tier to "paid" idempotently.

Endpoints
- POST /api/stripe/checkout (require_auth) — creates a hosted
  Checkout Session in subscription mode, passes user.id as
  client_reference_id + email as customer_email, returns the URL
  for the page-side JS to redirect to. Reuses an existing
  stripe_customer_id to avoid duplicate Stripe customers on repeat
  checkouts. allow_promotion_codes=True so the referral-credit
  redemption can attach a coupon at checkout once that flow ships.
- POST /api/stripe/portal (require_auth) — mints a Stripe Customer
  Portal session. Used by /settings; returns 404 until the user has
  a stripe_customer_id (i.e. completed at least one checkout).
- POST /api/stripe/webhook — signature-verified via
  stripe.Webhook.construct_event. Idempotent via UNIQUE on
  stripe_events.event_id. Event dispatch:
    checkout.session.completed       → grant paid, store IDs
    customer.subscription.created    → grant paid (active/trialing)
    customer.subscription.updated    → grant paid (active/trialing)
    customer.subscription.deleted    → drop to free, clear sub id
    invoice.paid / failed            → audit only
    charge.refunded                  → audit only
  Stripe-SDK objects don't expose dict.get(); we use the SDK for
  signature verification then re-parse the JSON body for handler
  dispatch — cleaner than reaching into StripeObject internals.

Schema (migration 0019)
- users.stripe_customer_id, users.stripe_subscription_id (nullable
  String(64), UNIQUE on customer_id).
- stripe_events table mirroring polar_events: event_id (unique),
  event_type, received_at, processed_at, error, raw payload
  (truncated to 16 KiB).

Settings (.env)
- STRIPE_API_KEY            (rk_test_… for dev, rk_live_… for GA)
- STRIPE_WEBHOOK_SECRET     (whsec_… from the dashboard endpoint)
- STRIPE_PRICE_MONTHLY      (price_xxx for £7/month)
- STRIPE_PRICE_ANNUAL       (price_xxx for £70/year)

Pricing page
- Free tier CTA unchanged.
- Paid CTA branches three ways: paid → "Manage subscription" to
  /settings; logged-in free → two buttons (£7/mo, £70/yr) that POST
  to /api/stripe/checkout and redirect; anonymous → /login?next=/pricing.
- Inline JS intercepts the button click, calls the checkout
  endpoint, redirects on success, surfaces errors via alert(). No
  Stripe.js dep — we use the hosted-checkout URL directly.

Polar handler stays in place for berengar.io / flyroom.net which
still ship through Polar. polar_* and stripe_* columns coexist
independently on the User row.

Tests
- 9 in tests/test_stripe_billing.py covering: bad signature → 401,
  missing signature → 400, checkout.session.completed flips tier +
  stores IDs, subscription.updated active grants paid,
  subscription.deleted drops to free with customer id preserved,
  replayed event id is no-op (one row in stripe_events),
  unknown event acked 200, checkout endpoint mocks the SDK and
  returns the hosted URL, checkout requires login.
- Full suite: 221 passed, 5 skipped.

6c13f855e9 polar: build /api/polar/webhook handler
Standalone router for inbound Polar (merchant-of-record) deliveries.
No bearer-token dep — authenticity comes from the Standard Webhooks
HMAC instead. Wired up so it's safe to deploy dark: empty
POLAR_WEBHOOK_SECRET makes the endpoint return 503 (loud) rather than
accept unsigned events.

Behaviour
- Standard Webhooks signature verification: HMAC-SHA256 over
  `{webhook-id}.{webhook-timestamp}.{body}`, base64 secret prefixed
  whsec_, ±5min replay window, constant-time compare against any of
  the space-separated v1 tokens.
- Idempotency via UNIQUE on polar_events.event_id — a replayed
  webhook-id short-circuits to 200 "duplicate" without re-running.
- Event dispatch table covers the 10 events we subscribed to:
  subscription.{created,active,updated,uncanceled} -> tier=paid +
  persist polar_customer_id / polar_subscription_id.
  subscription.revoked -> tier=free (customer id kept so a resub
  matches the same User row).
  canceled / past_due / order.* / refund.created -> audit only.
- Unknown event types are acked 200 + recorded; we don't want to 4xx
  on something Polar adds in the future and trigger their retry loop.

Schema (migration 0018)
- users.polar_customer_id, users.polar_subscription_id (both nullable
  String(64)); UNIQUE on polar_customer_id so two users can't claim
  the same Polar identity.
- polar_events table: event_id (unique), event_type, received_at,
  processed_at, error, raw payload (truncated to 16 KiB).

Tests
- 7 in tests/test_polar_webhook.py: bad signature -> 401, stale
  timestamp -> 401, missing headers -> 400, subscription.active flips
  tier to paid + stores IDs, subscription.revoked drops to free while
  keeping customer link, replayed webhook-id is no-op, unknown event
  is acked.
- Full suite: 212 passed, 5 skipped.

Operator next steps before saving the webhook in Polar
1. Pull this branch to prod and apply migration 0018.
2. Save the webhook in Polar pointing at
   https://read.markets/api/polar/webhook — Polar will accept the
   save even though our endpoint still 503s (no secret yet).
3. Copy the secret Polar reveals into the prod .env as
   POLAR_WEBHOOK_SECRET=whsec_... and restart the app.
4. Trigger a test event from Polar's dashboard to confirm 200 OK.

f1903e1e61 public: landing + pricing + legal pages, apex-ready, lawyer-reviewed
Adds the unauthenticated surface that's needed to invite outsiders:

  - Landing (/) — dual-purpose root: dashboard for logged-in users,
    landing for everyone else. New maybe_current_user soft-auth helper
    in app/auth.py supports it without disturbing the per-route
    require_token deps on /news, /log, /upload, /settings.
  - About, Pricing, Disclaimer, Terms, Privacy — own router
    (app/routers/public.py), no auth dep, shared public_base layout
    (brand link, thin nav, footer with legal links + ICO ref + date).
  - Editorial positioning: news aggregator with a macro brain; tagline
    "Understand markets. Don't gamble on them."; anti-trading-as-gambling
    stance carried through About and Landing.

Legal pass following an independent lawyer-style review:

  - Privacy: explicit UK-GDPR Art. 6 lawful-basis section; Art. 22
    automated-decision line; explicit consent for sessionStorage sync
    key (PECR); 30-day IP-log retention; Art. 21 objection right;
    Children clause; Art. 33/34 breach-notification clause;
    international-transfer mechanism (IDTA + UK Addendum). ICO
    registration ZC098928 surfaced at the top.
  - Pricing: paid-card AI-portfolio-analysis bullet rewritten to remove
    advice-shaped wording ("what would invalidate the posture" gone);
    added italic carve-out citing FSMA / FCA COBS.
  - Disclaimer: separate EU/EEA carve-out + MAR 596/2014 Art. 3(1)(34)
    commentator safe-harbour; "qualifies the Terms" line; hallucination
    wording fixed.
  - Terms: cl.4 explicit AI-training prohibition + harassment line;
    cl.5 CCR 2013 14-day cancellation; cl.7 softened AI copyright
    claim under CDPA s.9(3) ambiguity; cl.8 proportionate suspension +
    pro-rata refund for paid users; cl.10 CRA 2015 Pt 1 statutory-rights
    carve-out from the liability cap; cl.11 right to close account on
    material change; cl.12 non-exclusive jurisdiction + UK consumer
    local courts.

Code-side enforcement of the Privacy claim:

  - openrouter.py: outbound OpenRouter calls now carry
    X-OR-Allow-Training: false. DeepSeek doesn't expose a per-request
    flag; the Privacy page discloses this caveat verbatim.

Apex domain prep:

  - branding.APP_URL flipped to https://read.markets (was app.). DNS for
    the apex already resolves; pending operator NPM step is a cert that
    covers the bare apex + a 301 from app.read.markets. No hard-coded
    subdomain references remain in code (verified with grep).

Nav + chrome:

  - app dropdown gains Pricing / Terms / Privacy / Disclaimer links.
  - login.html gains a small legal-links footer for the
    highest-leverage moment to surface them.

f326b41a08 sync: encrypted cloud backup for portfolios + settings UX rework
Adds opt-in client-side-encrypted portfolio sync (paid). Browser
PBKDF2(PIN) → AES-GCM, server HKDF(pepper, user_id) outer wrap;
server stores opaque bytes only. Sliding-window rate limit on GET.

  - new portfolio_sync table (migration 0015)
  - POST/GET/DELETE /api/portfolio/sync + /status
  - app/services/portfolio_sync.py crypto + rate limit
  - app/routers/sync.py paid-gated
  - app/static/js/portfolio-sync.js WebCrypto wrapper
  - settings page: enable/disable + PIN modal
  - PORTFOLIO_SYNC_PEPPER setting (warn on startup if missing)

Settings + import rework:

  - /upload merged into /settings#import (legacy route 302s)
  - drop CSV → auto-parse → preview → Import only / Import & sync
  - nav slimmed to Dashboard / News / Log
  - Settings + Logout moved to a user dropdown
  - brand logo links to /

Collateral fixes:

  - settings 500: re-fetch User in current session before mutating
    referral_code (assign_code_if_missing was refreshing a User
    loaded in the auth dep's now-closed session)
  - csv_import: distinct error for unfunded T212 pies (all qty=0)
  - db.py: drop pool_pre_ping (aiomysql 0.3.2 incompat); pin
    isolation_level=READ COMMITTED to avoid gap-lock deadlocks
  - alembic env: disable_existing_loggers=False so in-process
    migrations don't silence uvicorn's loggers
  - docker-compose.override.yml: dev-only volume mount + --reload

824d849c63 brand: rename product to "Read the Markets" (read.markets)
The product is now "Read the Markets" served at https://read.markets,
with the app at https://app.read.markets. "Cassandra" survives only as
the in-product AI persona (system prompt + "Ask Cassandra" chat label).

Centralised the brand in app/branding.py: BRAND_NAME, BRAND_SHORT,
DOMAIN, SITE_URL, APP_URL, EMAIL_FROM_DEFAULT. Jinja templates pull
{{ BRAND_NAME }} via globals registered in templates_env.py; Python
code reads branding.BRAND_NAME directly. The future-rename surface
is now a one-liner.

Updated: FastAPI app title, every page title (dashboard, news, log,
settings, upload, login, verify), header brand div, auth-card brands,
OTP email subject + HTML + plain-text bodies (incl. uppercase header
tag), OpenRouter X-Title + HTTP-Referer attribution headers, README.
Email tests now assert against branding.BRAND_NAME rather than the
literal string.

Internal identifiers deliberately kept on the legacy "cassandra" name
to avoid invalidating live sessions / advisory locks / configs:
cookies (cassandra_session, cassandra_pending) + itsdangerous salts,
MariaDB GET_LOCK keys, CASSANDRA_TOKEN env var, cassandra.css filename,
pyproject package name, localStorage prefs, outbound User-Agent strings.

6e7f57c6b2 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.

480fd311c5 phase A: user accounts + session-cookie auth
Replaces the static bearer-token gate with a real auth boundary. The
existing CASSANDRA_TOKEN path is retained as an admin / scripting escape
hatch — kept compatible by aliasing require_token to require_auth.

- New users table (migration 0007): email, argon2 password_hash, tier,
  email_verified (declared but not enforced until phase E), settings_json
  for the tone/analysis/anchor knobs we'll wire in phase D.
- app/services/auth_service.py: argon2-cffi password hashing with timing-
  attack-resistant authenticate() (always runs a hash verify even on
  unknown-email to deny a username-enumeration oracle).
- app/auth.py rewritten: require_auth returns a CurrentUser with either
  is_admin=True (bearer path) or a User object (session path). Failing
  requests get 303 → /login for HTML, 401 for API. Sessions signed with
  itsdangerous against CASSANDRA_SESSION_SECRET; 14-day TTL.
- app/routers/auth.py: /login, /signup, /logout. Login form preserves the
  ?next=… param for redirect-after-login. Signup respects a new
  CASSANDRA_SIGNUP_ENABLED flag.
- Standalone /login + /signup templates (no app chrome). base.html grows
  a user chip + logout link in the header (reads request.state.current_user).

Phase A's main known limitations are documented in the plan: email
verification is declared but not enforced; session revocation is
best-effort (cookie-only, not DB-backed). Both land in phase E.

a10409c02b initial commit — cassandra v0.1
Containerised macro-strategy dashboard: 4-panel web UI (indicators,
portfolio, flash news, AI strategic log), MariaDB store, hourly
ingestion jobs, OpenRouter-backed AI analysis.

Ports the four prototype scripts in the parent dir (market_pulse,
flash_news, trading212, strategic_log) into async services backed by a
persistent DB and served via FastAPI + Jinja2 + HTMX. APScheduler runs
as a separate compose service for crash-safety and easier restarts.

Portfolio composition + position names come live from Trading 212;
news per-ticker headlines reuse those names. Tone (NOVICE/INTERMEDIATE/
PRO) and analysis style (DRY/SPECULATIVE) are env-configurable and
stored on each log row so historical entries show what produced them.

Default model is deepseek/deepseek-v4-flash (overridable via env).
Light/dark theme toggle, sans-serif for prose surfaces, monospace for
data. Bearer-token auth, OpenRouter monthly cost cap, RSS feeds auto-
disabled on consecutive failures.
