EduMatcher v0.52.0

[v0.52.0] - 2026-10-23

Release Type: major (due to breaking change in DB schema)

📋 Summary

This release adds post-run simulation forensics and longer audit and statistics retention for investigating trading sessions. It also improves the Trading Workstation and fixes fill reporting and quote handling during cascaded matching.

⚠️ Breaking Changes

• Updated the statistics database to schema version 8, replacing order_events.trade_id with the JSON-array field trade_ids; existing databases are not migrated, so archive the old database and let pm-stats create a new one

✨ Additions

• Added simulation-forensics tooling with cross-store trade reconciliation, double-entry bookkeeping, and order-lifecycle checks, plus Markdown and JSON reports
• Added pm-audit --max-file-mb and --backup-count options for configurable audit-log retention
• Added a Trading Workstation symbol drawer with market details and per-minute trade-count and traded-value charts

🚀 Improvements

• Expanded AI-simulation audit retention to approximately 25 GB and automated order-event retention to two days for post-run analysis
• Enabled the same 09:00–16:05 session schedule on weekdays and weekends in both 300-symbol example setups
• Moved Trading Workstation navigation to its own row and placed session information in the top bar

🐛 Bug Fixes

• Fixed missing fill events for cascaded and triggered-stop orders that execute before being cancelled
• Fixed triggered stops matching against a quote's stale sibling leg after the other leg fills
• Fixed statistics fill records missing their associated trade IDs
• Fixed OHLC chart times not using the configured session time zone
• Fixed GUI tooltips appearing off-screen in zoomed layouts

📚 Documentation

• Documented audit-retention options, the statistics schema change, and quote-leg fill behavior
• Added simulation-forensics workflow and check documentation, and updated the example schedule descriptions
• Added test API-key login guidance to the curl installer

🛠 Internal

• Added regression coverage for cascaded fills, quote-sibling cancellation, audit and statistics retention, simulation-forensics checks, and Trading Workstation behavior
• Added forensic target to top level Makefile , use as make forensics DATA=<new data dir> OUT=<dir>
