- Portfolio, holdings, prices, symbols packages with Telegram command handlers
- Handlers: trade_topup (add credits), trade_buy, trade_sell, trade_convert (coming-soon), trade_stats
- Per-user keylock for concurrency safety
- KBS (VN) as price source; ticker validation regex ^[A-Z0-9]{1,16}$
- Scope-trimmed: no SQL history, no retention cron, no daily refresh, no leaderboard, no forex
(matches upstream miti99bot's current VN-stocks-only state)
- Full unit test coverage for format, portfolio, prices, symbols, handlers
