- tradingagents/dataflows/universe.py: single source of truth for ticker
universe; all scanners now call load_universe(config) instead of
duplicating the 3-level fallback chain with hardcoded "data/tickers.txt"
- scripts/prefetch_ohlcv.py: nightly script using existing ohlcv_cache.py
incremental logic; first run downloads 1y history, subsequent runs append
only new trading days
- .github/workflows/prefetch.yml: runs at 01:00 UTC daily, before all other
workflows; commits updated parquet to repo
- Updated 6 scanners: minervini, high_52w_breakout, ml_signal, options_flow,
sector_rotation, technical_breakout — removed duplicate DEFAULT_TICKER_FILE
constants and _load_tickers_from_file() functions
- minervini, high_52w_breakout, technical_breakout: replace yf.download()
with download_ohlcv_cached() — reads from prefetched cache instead of
hitting yfinance at discovery time
- default_config.py: added discovery.ohlcv_cache_dir config key
- data/ohlcv_cache/: initial 1y backfill (588 tickers, 5.4MB parquet)

- iterate: CRITICAL note that all writes must use file tools, not narration
- iterate: new Step 5.5 — auto-registers one forward-test hypothesis per run
when a code change needs live-data validation
- research-strategy: cron changed from Monday-only to daily at 07:00 UTC

gh pr create/list/edit were defaulting to TauricResearch (upstream).
Added --repo Aitous/TradingAgents to all gh calls in iterate,
research-strategy workflows and slash commands.

Uses google-genai SDK with gemini-2.5-flash-lite — same model already
used by the discovery pipeline, so no new secret needed (GOOGLE_API_KEY).
Removed ANTHROPIC_API_KEY from hypothesis-runner.yml.

- Add permissions: contents: write so git push works (was failing with 403)
- Add continue-on-error: true on discovery step so partial output still commits
- Change all commit/tracking/position steps to if: always() so they run regardless of discovery outcome
- Use commit-then-pull-rebase-then-push pattern to handle branch divergence
- Fix minervini scanner missing from scanners/__init__.py (enabled in config but never loaded)
- Fix .gitignore: results/* + !results/discovery/ so CI run logs can be committed
