- handleSave now shows a red toast "Lancez d'abord un backtest" instead of
silently returning when activeRun is null (was completely invisible to user)
- All toasts now color-coded: green (emerald) for success, red for errors
- list_runs now includes context_snapshot so market data table shows when
loading a historical run from the right panel

Fix: history runs now always show results — create synthetic selected preset
from run data when no matching preset found (was broken for custom events).
Also force mode='events' and reset matchResults on history load.
Discover tab: new "Discover" panel in left sidebar (AI knowledge search).
- GPT-4o generates 6 matching events from a free-text query (date, assets, hint)
- Confidence score + category badge per event
- Click → pre-fills experiment form exactly like a preset → ready to Run
- Backend: POST /api/pattern-lab/discover (DiscoverRequest, sorted by confidence)
- Frontend: useDiscoverEvents hook + DiscoveredEvent type + Discover UI with
Enter-to-search, spinner, empty states

- instruments.ts: 90 IB-options-tradable instruments in 12 categories
(US Indices, Europe, Asia, EM, Sectors, Forex, Bonds, Metals, Energy,
Agriculture, Crypto, Volatility) — EUR/CHF, Cotton, etc. all included
- PatternExplorer: replace text input in Instrument Lens with categorised
grid picker (category pill filters + search + custom ticker fallback)
- PatternLab: add Instrument Scan tab alongside Event Presets
- Pick any instrument from the shared categorised picker
- Set period (start/end date) + horizon per pattern
- AI scans the full period: identifies 4-6 key pattern instances each with
their own entry date, expected move, strategy
- 'Evaluate outcomes' fetches actual price at T+horizon per pattern
- 'Save pattern' promotes any instance to the Pattern Library
- backend/services/pattern_lab.py: run_instrument_scan() + evaluate_instrument_outcomes()
(per-pattern analysis_date vs shared date in event mode)
- backend/routers/pattern_lab.py: POST /instrument-scan + POST /evaluate-instrument/{id}
- useApi.ts: useInstrumentScan + useEvaluateInstrumentScan hooks

- Remove all built-in patterns (no proof of legitimacy); seed_builtin_patterns is now a no-op
- DB: add backtest_lab_runs table + backtest_hits/runs_count columns on patterns
- services/pattern_lab.py: build_historical_context (yfinance + RSI/MA200),
run_ai_backtest (GPT-4o as historical analyst), evaluate_outcomes (actual moves at T+horizon)
- routers/pattern_lab.py: POST /run, POST /evaluate/{id}, GET /runs, DELETE /runs/{id},
POST /save-pattern (promotes hit pattern to library with reliability counters)
- PatternLab.tsx: 34 preset events 2015-2025 (macro/geo/credit/fx/commodities/volatility/tech),
3-panel layout — preset selector + wizard + run history, market data table,
AI pattern cards with hit/miss outcome display, Save to Library button
- useApi.ts: usePatternLabRuns, useRunPatternLab, useEvaluatePatternLab, useSaveLabPattern, useDeleteLabRun
- Sidebar + App.tsx: /pattern-lab route + FlaskConical nav link
