Five existing migrations used op.alter_column / op.create_unique_constraint /
op.drop_constraint / op.create_foreign_key directly on the users + quotes +
quotes_daily tables. SQLite has no native support for those operations and
requires Alembic's batch_alter_table copy-and-rename workaround.
This wasn't noticed until now because the test suite uses
Base.metadata.create_all to materialise schema, not the migration chain
itself; and prod is MariaDB. But running `alembic upgrade head` against
a fresh SQLite database (developer onboarding, CI smoke tests, the
test container's own bootstrap) would fail at 0005.
Fixes:
- alembic/env.py: set render_as_batch=True when the dialect is SQLite.
This auto-wraps any future autogenerated migration but doesn't
retroactively rewrite existing op.* calls.
- 0005 (widen quotes.symbol), 0013 (referrals), 0018 (polar webhook),
0019 (stripe), 0023 (users.lang index + qd_symbol widen) explicitly
wrap their problematic ops in `with op.batch_alter_table(...) as bop`.
Now `alembic upgrade head` + `alembic downgrade base` round-trip cleanly
on a fresh SQLite database. MariaDB prod behaviour unchanged.

Three new data sources hooked into the existing SOURCES registry. All
open APIs, no keys:
- EUROSTAT: prefix EUROSTAT:dataset?dim=val&... — current EU bond
yields (Bund/OAT/BTP/EZ) and Eurozone economic indicators that
FRED's OECD-mirror series stopped updating in 2022-2023.
- ONS: prefix ONS:topic/cdid/dataset — current UK CPI, unemployment,
GDP, industrial production. Replaces the 5+ month-stale FRED
LRHUTTTTGBM156S mirror.
New indicator groups in default.toml feed the strategic/fundamental
lens we converged on: valuation (CAPE/Buffett anchors), bubble_watch
(SKEW/VVIX/RSP vs SPY/HYG vs TLT/IPO/crypto), economy (multi-region,
ALL current-or-stale-flagged), bonds (UK/EU/US/JPN sovereign yields).
Indicator panel now opens with an AI "read" interpretation per group
(generated hourly at :07 UTC alongside an aggregate cross-group read
shown in the dashboard header). The aggregate is grounded by a markets
strip — NYSE/LSE/Frankfurt/Tokyo/HK/Shanghai with open/closed LEDs and
next-open countdown, computed locally from each exchange's tz.
Other UX bits: indicator-row tooltips populated from TOML notes;
rows whose last observation is >90 days old get a 'stale' chip;
ghost symbols (in DB but no longer in TOML) filtered out of the
panel; Eurostat/ONS symbols display as short codes rather than the
full API path.
