Dispatching only to the pricing specialist is efficient for a pricing-only question. A disagreement between security and legal interpretations of retention rules cannot be settled by narrowing the work to prices; the coordinator must compare the competing interpretations against the governing source.

Scheduling legal work before dependent tasks solves a prerequisite-order problem, not a disagreement between two completed interpretations of the same policy. Both the security and legal agents have returned conflicting claims. The coordinator must compare the authoritative policy text and document the unresolved difference instead of simply changing execution order.

Routing a refund specialist's dependency through the coordinator controls agent-to-agent communication. It does not resolve two contradictory interpretations of a retention policy already returned by security and legal agents. The coordinator needs an evidence-backed cross-domain decision or an explicit unresolved finding.

Agent throughput is not evidence that a retention-policy interpretation is correct. A model that completed more requests is not necessarily interpreting the current contract correctly. Resolve the disagreement against effective policy documents, jurisdiction, scope and dates; escalate if the authoritative text remains ambiguous.

The coordinator should receive decision-relevant summaries and evidence pointers, not every raw intermediate token. It would leave the stated need to route inter-specialist dependencies through the coordinator unresolved.

Independent agent analysis can proceed in parallel, but overlapping stateful edits require an explicit ownership and integration strategy to avoid lost updates. Although useful elsewhere, it is not the direct mechanism to route inter-specialist dependencies through the coordinator.

Bypassing the coordinator breaks the required hub-and-spoke assignment flow and makes the fraud inquiry difficult to attribute. The refund specialist should identify its missing information and return that need to the coordinator, which can invoke the authorized fraud specialist and record the handoff.

Dispatching only to pricing chooses the specialist for a pricing question; it does not preserve source attribution after multiple agents have already returned findings. The reported failure is missing claim ownership in the merged output. Store the source URL or document locator and producing agent for each claim so a reviewer can trace it.

Hub-and-spoke routing can centralize task assignment and result collection, but routing alone does not preserve which source supports each individual claim. A merged answer still needs claim-level provenance: producing agent, source identifier and relevant version. Store that mapping before combining the parallel findings.

Concurrent independent branches do not need to run in sequence. That addresses a different part of the system, not the requirement to preserve specialist and citation provenance in merged results.

A pricing-only routing decision would ignore the fact that an assigned fourth specialist crashed. Reassigning focus to pricing cannot recover the missing workstream or establish that it completed. The coordinator should carry a failure status and either retry the missing specialist under budget or mark the associated section incomplete.

Independent agent analysis can proceed in parallel, but overlapping stateful edits require an explicit ownership and integration strategy to avoid lost updates. This capability does not directly manage partial multi-agent completion transparently.

The coordinator should receive decision-relevant summaries and evidence pointers, not every raw intermediate token. It would leave the stated need to manage partial multi-agent completion transparently unresolved.

The longest-branch latency model estimates the duration of independent parallel research; it does not encode a prerequisite such as legal approval before region selection. A fast region-selection job can still be invalid if it starts before residency constraints are known. Represent the dependency edge and run only unrelated work concurrently.

Conflicts between specialist findings require evaluation against primary evidence. This alternative does not establish how to schedule dependent subtasks after prerequisite findings in the stated workflow.

Attribution is necessary to evaluate contradictions, rerun a defective workstream and cite sources. Although useful elsewhere, it is not the direct mechanism to schedule dependent subtasks after prerequisite findings.

Routing a refund specialist's request back to the coordinator addresses inter-agent communication, not payload size. Here the coordinator already receives enormous document dumps. Require bounded findings with evidence locators and specific unresolved questions so integration does not consume the entire context budget.

A coordinator must handle partial results explicitly. That addresses a different part of the system, not the requirement to limit subagent return payloads while retaining evidence.

Serializing writes protects shared files when two agents edit the same state. The current failure is neither a write conflict nor a merge race: it is the volume of returned documents. Require brief evidence-backed conclusions and evidence handles from each subagent so the coordinator can verify details on demand without ingesting thousand-page dumps.

Gap detection can launch missing research, but it does not stop a financial-analysis subagent from altering production infrastructure. The risk is excessive tool authority, not incomplete report coverage. Remove infrastructure-write capabilities and enforce the access boundary on the actual execution service.

Independent agent analysis can proceed in parallel, but overlapping stateful edits require an explicit ownership and integration strategy to avoid lost updates. It would leave the stated need to enforce specialization with tool permissions rather than naming alone unresolved.

Conflicts between specialist findings require evaluation against primary evidence. This alternative does not establish how to enforce specialization with tool permissions rather than naming alone in the stated workflow.

Concise cited handoffs make results easier to integrate, but an otherwise excellent report can still arrive twice after a retry. Without a stable work-item ID and lifecycle ledger, the coordinator may merge both copies. Deduplicate completions by task identity rather than by the length or quality of the returned report.

Escalating contradictory claims helps reconcile interpretation, whereas this incident is duplicate delivery of the same workstream result after retries. A result may be perfectly accurate and still be merged twice. Stable work-item identifiers and lifecycle state allow the coordinator to recognize and ignore duplicate completions.

Independent agent analysis can proceed in parallel, but overlapping stateful edits require an explicit ownership and integration strategy to avoid lost updates. Although useful elsewhere, it is not the direct mechanism to deduplicate concurrent subagent results by task identity.

Dispatching only the pricing specialist would omit the other three required investigations. The question asks how long all four independent branches take when they run concurrently, not which specialist to choose. The limiting branch is the 11-second investigation, with additional scheduling and integration overhead.

Attribution is necessary to evaluate contradictions, rerun a defective workstream and cite sources. That addresses a different part of the system, not the requirement to reason about parallel fan-out critical paths.

Independent agent analysis can proceed in parallel, but overlapping stateful edits require an explicit ownership and integration strategy to avoid lost updates. This capability does not directly reason about parallel fan-out critical paths.

Invoking every subagent for a narrow pricing question increases latency and retrieval expense without improving the required coverage. Taxonomy and security workstreams can be necessary when the request also concerns product eligibility or payment restrictions, but those dependencies have not been established here. Dispatch should follow the user's requested information rather than a blanket all-agent fanout.

A security review does not itself retrieve or validate the current pricing record. Starting with the security agent would skip the required domain-specific evidence and could deliver assumptions about prices rather than the requested figures. The coordinator can engage security later if a pricing proposal reveals a security or policy issue.

Conversation memory can be stale when vendors change prices, contract tiers or effective dates. Even an apparently plausible remembered number is not a current pricing source. For a request that explicitly needs a price decision, the coordinator should invoke the authorized pricing capability and preserve the evidence it returns.

Structured claim-to-source handoffs support auditability after specialist work is returned, but they do not isolate incompatible legal and technical source contexts during analysis. Delegate separate bounded specialist assignments and let the coordinator reconcile their cited conclusions; a citation contract alone cannot replace independent workstreams.

A deterministic fixed-order workflow suits a known sequence of checks. The legal and technical assessments here require separate evidence and expertise, not three prescribed sequential operations. Isolate each specialist's source context and have the coordinator reconcile the two cited conclusions rather than force them into one undifferentiated chain.

The coordinator must not promote provisional inferences into facts merely because a subordinate returned polished prose. The direct remedy is “Delegate bounded analyses to separate specialist subagents and synthesize their cited results”, which the alternative does not itself accomplish. Context isolation reduces cross-contamination while the coordinator handles final reconciliation and source accountability.
