Future Work

No work here is blocking - we're in a good state. Items below are ordered roughly by priority within each section. Priority labels (HIGH / MEDIUM / LOW) mark items that deserve explicit ranking; unlabeled items are "someday, if the mood strikes."

Infra / performance

• HTTP connection pooling. Parallel server sync in loadAllPrices spawns up to 8 threads, each with its own HTTP connection. Could reuse connections to reduce TCP handshake overhead. Only matters with very large portfolios (100+ symbols) hitting ZFIN_SERVER.
• Streaming cache deserialization. Cache store reads entire files into memory (readFileAlloc with 50MB limit). For portfolios with 10+ years of daily candles, this could use significant memory. Keep current approach unless memory becomes a real problem.
