Greptile Summary

• Adds OTel LLM metrics (ttft, ttat, tps, token counters, request counter with status) centralized in llm_metrics.py; TemporalStreamingHooks now extends LLMMetricsHooks so token/request metrics fire consistently across streaming and (future) sync paths.
• Refactors SGPSyncTracingProcessor and SGPAsyncTracingProcessor to be stateless — per-span _spans dict removed and replaced with an idempotent _build_sgp_span() helper, fixing a silent span-drop bug on Temporal cross-pod deployments where START and END land on different workers.
• API surface additions: created_at parameter on messages.create and messages.batch.create; set_tracing_disabled(True) added to generated templates to stop the openai-agents SDK from shipping traces to api.openai.com via OPENAI_API_KEY.

Confidence Score: 4/5

Safe to merge; only a P2 monitoring gap and a pre-existing template issue already flagged in prior reviews

No P0/P1 bugs in the changed code. The stateless SGP processor refactor is well-tested and fixes a real cross-pod drop issue. The one P2 finding (sync ACP error path not wired to record_llm_failure) is a monitoring completeness gap, not a runtime failure.

src/agentex/lib/cli/templates/temporal-openai-agents/project/workflow.py.j2 (unconditional SGP tracing, already flagged in prior reviews); src/agentex/lib/core/observability/llm_metrics_hooks.py (no error hook for sync path)

Important Files Changed

Filename	Overview
src/agentex/lib/core/observability/llm_metrics.py	New OTel metric instruments for LLM calls (requests, ttft, ttat, tps, token counters); singleton get_llm_metrics() and classify_status() helper with bounded status labels.
src/agentex/lib/core/observability/llm_metrics_hooks.py	LLMMetricsHooks emits success request counter + token counters via on_llm_end; record_llm_failure covers error path for temporal streaming only — sync ACP error path is untracked.
src/agentex/lib/core/temporal/plugins/openai_agents/models/temporal_streaming_model.py	Adds ttft/ttat/tps OTel metric recording to streaming loop; record_llm_failure wired in except block; stream_start_perf captured before await for accurate latency.
src/agentex/lib/core/tracing/processors/sgp_tracing_processor.py	Stateless refactor: per-span _spans dict removed; _build_sgp_span() builds SGPSpan idempotently on both start and end, fixing cross-pod span-drop for Temporal deployments.
src/agentex/lib/core/tracing/tracing_processor_manager.py	Removes AgentexTracingProcessor from default tracing processors (breaking change per CHANGELOG); lazy-init logic dropped.
src/agentex/lib/cli/templates/temporal-openai-agents/project/workflow.py.j2	Adds set_tracing_disabled(True) and SGP_CLIENT_BASE_URL wiring; add_tracing_processor_config is still called unconditionally (no SGP_API_KEY/SGP_ACCOUNT_ID guard), unlike the sibling acp.py.j2 template.
src/agentex/lib/cli/templates/sync-openai-agents/project/acp.py.j2	Adds set_tracing_disabled(True) and SGP_CLIENT_BASE_URL wiring; tracing processor correctly guarded by if SGP_API_KEY and SGP_ACCOUNT_ID.
src/agentex/_models.py	Adds EagerIterable / _EagerIterable for eager pydantic validation of generator inputs; type reconstruction, str-subclass guard, and serialize-as-list serializer are all correct.
src/agentex/lib/core/temporal/plugins/openai_agents/hooks/hooks.py	TemporalStreamingHooks now inherits from LLMMetricsHooks, wiring token/request metrics into the async temporal path.
src/agentex/_files.py	Adds missing f-string prefix to file-type error message — was emitting a literal placeholder string before this fix.
