+ QmjRt^RIt^RIHt0RmtRRlt]R8Xd$]P!]!4'd^M^4R#R#)aw Single source of truth for "is the TSX open today" -- weekend + full-closure holiday check. Every cron job in this project (run_daily_scan.sh, fetch_prices.py, check_positions.sh) calls this instead of keeping its own copy of the calendar, so the list can't silently drift the way run_daily_scan.sh's filter thresholds once did (see CLAUDE.md). Deliberately does NOT skip on early-close days (e.g. Dec 24, 1pm EST close) or settlement-only holidays where TSX stays open for trading (e.g. National Day for Truth and Reconciliation, Sept 30 -- TMX explicitly keeps the market open that day; only settlement is affected). Only full closures block a run.
