Verified this is real: once item.trace is non-empty, billable_steps in CostRoutingCoordinator.retrieve_batch() is non-empty too, so the if not records: fallback that reads the item's own authoritative prompt_tokens/completion_tokens never runs — a trace step lacking its own usage degrades a known-measured item to unavailable.

Not pushing a fix for this one: the two remediations you propose (make item-level usage authoritative regardless of trace presence, vs. define and implement an explicit trace-step usage-aggregation rule) are genuinely different accounting semantics, and this loop is shared with item.race_usage (a pre-existing, unrelated source feeding the same billable_steps list) — so whichever rule I pick here changes behavior for that path too, not just the new trace path this PR adds. That's a real design call for whoever owns cost_router.py's accounting semantics, not something I want to guess at unilaterally in a security-scoped PR. Flagging for the author/a follow-up rather than resolving this thread.

@seonghobae, agreed. This is a valid accounting regression.

The fix requires an explicit policy for precedence between item-level usage and billable_steps usage. That policy also affects the existing item.race_usage path.

Keeping this thread open is correct for this security-scoped PR. Do you want me to open a follow-up GitHub issue for the cost_router.py accounting-policy decision and regression coverage?

Learning: In `contextual_orchestrator/cost_router.py`, `CostRoutingCoordinator.retrieve_batch()` uses a shared `billable_steps` path for both `BatchResultItem.trace` and `BatchResultItem.race_usage`. If this path is non-empty but its steps have no usage, the existing item-level `prompt_tokens` and `completion_tokens` fallback does not run. Any fix requires an explicit accounting policy for item-level usage versus step-level usage.

Yes, please open the follow-up issue — that keeps the accounting-policy decision (item-level usage vs. billable_steps/race_usage precedence) tracked with the reproduction and regression-test pointer instead of relying on this PR thread staying findable after merge.

## 요약

`CostRoutingCoordinator.retrieve_batch()`의 usage 우선순위 정책을 명시하고 구현해야 합니다.

현재 `BatchResultItem.trace` 또는 `BatchResultItem.race_usage`가 있으면 공통 `billable_steps` 경로가 사용됩니다. 이 단계에 `usage`가 없으면, 유효한 `BatchResultItem.prompt_tokens` 및 `BatchResultItem.completion_tokens`가 있어도 item-level fallback이 실행되지 않습니다. 그 결과 측정된 usage와 cost가 `unavailable`로 기록될 수 있습니다.

## 재현 조건

1. `BatchResultItem.prompt_tokens=12` 및 `BatchResultItem.completion_tokens=8`을 설정합니다.
2. `BatchResultItem.trace` 또는 `BatchResultItem.race_usage`에 `usage`가 없는 step을 하나 이상 설정합니다.
3. `CostRoutingCoordinator.retrieve_batch()`를 실행합니다.
4. 현재 동작에서는 item-level usage fallback이 건너뛰어질 수 있습니다.

## 필요한 변경

- `contextual_orchestrator/cost_router.py`의 `CostRoutingCoordinator.retrieve_batch()`에서 item-level usage와 `billable_steps` usage의 우선순위 정책을 결정합니다.
- 이 정책은 `BatchResultItem.trace`와 기존 `BatchResultItem.race_usage`에 동일하게 적용해야 합니다.
- 선택한 정책에 따라 usage 및 cost 계산을 구현합니다.
- 정책의 근거와 fallback 조건을 코드 또는 관련 문서에 명확히 기록합니다.
- 회귀 테스트를 추가합니다.

## 영향 범위

- `contextual_orchestrator/cost_router.py`
  - `CostRoutingCoordinator.retrieve_batch()`
  - `billable_steps` 기반 usage 및 cost 계산
- 관련 batch retrieval 회귀 테스트

## 완료 조건

- trace step에 `usage`가 없어도 authoritative item-level usage `{prompt_tokens: 12, completion_tokens: 8}`를 처리하는 정책이 명확합니다.
- 선택한 정책에 따라 measured usage와 cost가 일관되게 계산됩니다.
- 동일 정책이 `trace` 및 `race_usage` 경로에 적용됩니다.
- 위 재현 조건을 검증하는 회귀 테스트가 있습니다.

🟡 Provider batches cannot return traces

For PgLlmBatchBackend jobs, include_orchestration_trace=true authorizes retrieval after submission omitted that flag. Default-hidden gateways therefore return no trace.

CodeRabbit's latest pass raised the same gap twice more (outside the diff range, so no separate inline threads: batch_routing.py:202 on BatchRequest.to_jsonl_line() not requesting trace at submission time, and server.py:3262-3264 on _validate_batch_requests not threading expose_trace into the submitted BatchRequest) — replying here rather than splitting three threads over one issue.

Confirmed real and pre-existing: to_jsonl_line()'s submission payload (model, messages only) is unchanged by this PR, so a target gateway with expose_trace_by_default=False never captures trace to begin with, regardless of this PR's retrieval-time opt-in. This PR only gates disclosure of whatever trace is captured — it doesn't touch capture. Reconciling submission-time opt-in, persisted job metadata, and both local/provider backends (as your own prompt notes) is a real feature, not a one-line fix, and it's orthogonal to this PR's actual purpose (narrowing an existing over-disclosure). Leaving this open rather than resolving or attempting it here — it's a legitimate follow-up for whoever owns the batch-trace-capture path next.
