Robust Execution and Adaptive Timeout: implement adaptive timeout and robust retry

[keyboardstaff]

Adaptive Timeout Modes: off / basic / auto; supports base + per-1k with EMA profiling; default slow-model multiplier = 10, persisted across retries; global cap protection.

Resilient Retry & Key Rotation Unified error classification and mapping; exponential backoff with jitter; API key rotation on 429/503 triggers; masked key display in logs; full attempt history retained.

Streaming Robustness Forced flush of trailing packets to ensure no tokens are lost; shard-based parsing compatible with reasoning tags and native reasoning channels.

Tool JSON Parsing Strict JSON → DirtyJson fault tolerance → “final balanced object” recovery stage.

Safer Python Execution AST.parse validation; safe injection (via json.dumps); narrow-scope base64 fallback for triple-quote anomalies; isolated namespace execution.

Settings & UI Consistency

Only four adaptive global override keys are exposed: • chat_timeout_base • chat_timeout_per_1k • util_timeout_base • util_timeout_per_1k

UX Noise Reduction Recoverable “minor JSON misformat” is downgraded to non-error diagnostics: not written to history, not logged as an error, and does not trigger UI red dots.

Memory & Consolidation Merging process adopts adaptive timeout; parsing made more robust; conservative REPLACE threshold with concurrent re-validation; temporal metrics recorded.

Tests Completed • Adaptive timeout + slow-model multiplier persistence (default 10): Done • Retry + jitter + API key rotation: Done • Streaming tail flush: Done • Log noise reduction & key masking: Done • Layered JSON parsing & repair: Done • Hardened Python execution: Done • Prevent delegation loops & preserve memory sequence: Done • Misformatted JSON warnings downgraded (no history red dots): Done
