DeepSeek occasionally regurgitates the system prompt verbatim
("Constraints: ≤60 words...", "Example good: ..."). Three-pronged fix:
1. Removed the inline good/bad example blocks from the per-group and
aggregate system prompts — DeepSeek was treating them as templates
to copy. The hard constraints alone are clear enough.
2. Expanded the LEAK_PATTERNS list to catch the prompt-label echoes
that still occasionally slip through ("Key observations:", "The
indicators are:", "Must cite ...", "Should give ...", bare "Key:").
Cleanup now runs up to 6 passes for compound leakage.
3. Added looks_like_leakage() — if the cleaned output still contains
tell-tale phrases ("≤60 words", "instructions:", etc.), the summary
is skipped rather than persisted. Logs a 'leakage_detected' warning
and an ai_calls row with status=leaked so we can see the failure
rate over time. The previous good summary stays visible.

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.
