Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The change keeps validation failures scoped to individual requests while preserving shutdown for unhealthy engines and result-iteration failures. Before merging, the modified test module should add the required core marker so repository test validation remains compliant. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

One comment on the health check call, and the bot comments also look worth addressing

* Why? TensorRT-LLM can reject malformed or unsupported requests during synchronous preprocessing before executor submission. Treating these request-scoped failures as fatal unnecessarily restarts a healthy worker. * What? Return an error for pre-submit ValueError, TypeError, and NotImplementedError failures when the engine remains healthy. Preserve worker shutdown for unhealthy engines and errors raised during result iteration.

Overview:
Keep pre-submit validation errors request-local to prevent overly defensive TRT-LLM engine shutdowns.
Details:
TensorRT-LLM can reject malformed or unsupported requests during synchronous preprocessing before executor submission. Treating these request-scoped failures as fatal unnecessarily restarts a healthy worker.
Return an error for pre-submit ValueError, TypeError, and NotImplementedError failures when the engine remains healthy. Preserve worker shutdown for unhealthy engines and errors raised during result iteration.
