Signal Arcade v1.10.7 improves learning correctness, market-burst handling and reliability during long-running paper-trading sessions.
What’s improved
- More timely learning evidence: checkpoints approaching their collection deadline receive priority within their evidence lane, while preserving fairness and provider budgets.
- Less wasted refresh work: invalid route identities no longer repeatedly consume lookup slots. Changed identities retry, and temporary provider failures remain eligible.
- Stronger Entry proof: coverage follows the current Baseline and feature contract. Durable Policy identities preserve training/proof separation after older evidence is pruned. Linear and XGBoost candidates are compared only across matching validation populations.
- Correct Coach progression: winning Coach contenders earn fresh activation proof and remain monitored under their active identity. Waiting Coach proposals are protected from unrelated native candidate updates.
- More efficient burst processing: removes duplicate held-position valuations and database writes, reduces repeated learning calculations, and processes queued urgent evidence in small transactions without waiting to collect a batch.
- Safer cancellation and recovery: submitted work completes within its ownership boundary, and training rechecks market pressure before preparing a fit.
- Reliable long-season accounting: removes the 100,000-fill accounting limit and keeps Results and Seasons consistent across fills and season rollover.
- Better diagnostics: adds timing evidence for worker CPU, execution delays and contention. Diagnostics retain their separate 512 MiB allowance.
- Updated documentation: refreshed README, validation notes and 18 live screenshots in a dedicated v1.10.7 folder.
Learning and safety
Baseline boundaries, Champion permissions, Linear/XGBoost training recipes, independent proof and the 70% coverage requirement remain intact. Missing outcomes remain visible rather than being excluded to improve qualification.
These changes improve efficiency and evidence handling; they do not guarantee an Entry Champion or profitable trading.
Upgrading
Use Settings → Maintenance & updates → Prepare for upgrade, wait for Ready, and back up your data before updating.
This release introduces database schema 16. Existing bankroll, positions, seasons, learning records and Champion history are retained; no new season is required.
Migrations are forward-only. Rolling back to an older schema requires restoring its matching pre-upgrade data backup and image together.
