WalkthroughThe perf-optimize workflow now supports serial or parallel item batches. Parallel runs use isolated worktrees and an Integrator. State, progress, prompts, CLI help, and tests now cover batch execution, validation, and resume behavior. ChangesOptimization batch execution
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to This PR adds parallel candidate evaluation and integration, but the current behavior can misassign evaluator results, mishandle malformed or stale promotion verdicts, fail to support disaggregated integration, and leave interruption or cleanup recovery inconsistent. Generated candidate code also runs with broad worker authority without an established isolation boundary. These issues should be fixed or explicitly accepted before merge.

DISAGG_CAMPAIGNto the integrator prompt.The integrator launches and benchmarks a server.
workflow.pyline 1327 instructs it to "Launch and benchmark this combined state" with--extra_llm_api_options. The same stage prompt is prefixed with_disagg_directive()(workflow.pyline 1311), which tells the agent that its system prompt's Disaggregated serving section replaces all single-server guidance.In a disagg campaign the integrator never receives that section, so the directive points at absent content and the integrator has no valid launch procedure. The slurm block at line 184 already treats the integrator as a server-launching role, which confirms the intent.

Route the --clean worktree removal through the configured git transport.
gitops.use_cluster(ssh_alias) runs in run() at line 418, after the constructor. In a campaign whose task spec sets a cluster ssh alias, the checkout lives on the remote host, so these gitops.remove_worktree calls execute against the local filesystem, fail, and are swallowed by the except at line 282. --clean then leaves the stale worktree registrations that this block exists to remove.
task_data is already loaded at line 271, so the alias is available here.

Validate the integrator verdict fully before mutating the roadmap.
Two problems share one root cause: line 1344 re-reads the newest integrator entry and line 1345 accepts it after checking only decision.
-
latest_entryis not scoped to this round. The cache check at line 1302 comparesverdict.get("round") == round_no, but the post-run read does not. If the integrator writesintegration.mdand ends its turn without callingappend_integrator_progress,_require_stage_outputspasses and line 1344 returns the previous round's verdict. Round N's items are then accepted or failed using round N-1'sincluded_item_ids, andcurrent_bestis set from round N-1'smeasured_value. Therequired_toolsStop hook makes this unlikely, but it is an agent-side guard, not a deterministic orchestrator check. -
Line 1378 reads
verdict["measured_value"]and callsfloat()on it without a guard, after lines 1364-1373 have already writtenaccepted/failedstatuses to the roadmap. A missing or non-numeric value raisesKeyError/TypeErrorthere. The roadmap then records the items as accepted whilecurrent_beststill holds the previous value, so the next evaluator gates against the wrong reference. Compare_latest_evaluator_measured_valueand_latest_evaluator_curve, which defend against exactly this and degrade instead of raising.
Scope the post-run read to this round and validate the numeric fields before any roadmap write.

Guard counters the same way you guard the progress file.
_append now takes workflow._progress_lock because the optimizer and evaluator stubs run concurrently in parallel mode. The counters dict is shared by the same concurrent stubs but stays unguarded. The evaluator stub reads counters["evaluator"] and increments it as a separate read-modify-write.
Two consequences follow:
- Two workers can read the same index and consume the same verdict. One verdict is then never used.
test_multiple_items_applied_in_one_roundline 1192 assertssorted([one["measured_gain_pct"], two["measured_gain_pct"]]) == [3.0, 8.4], which fails when both items receive8.4. - The verdict-to-item mapping is not deterministic, which is why line 1195 has to accept either
108.4or111.6.
Take the same lock around the counter read and increment. The assertions can then pin exact values again.

Bind source edits and git review to the active runtime checkout.
When the two checkouts differ, this prompt permits the active runtime checkout to differ from task.yaml's trtllm_repo_path. However, agent-flow/agent_flow/workflows/perf_optimize/prompts/optimizer.py still directs code items to edit source in trtllm_repo_path. The Optimizer can edit the campaign checkout and then smoke-check a different active runtime worktree. Parallel candidates can then contaminate shared state or measure code that does not contain the edit.
Use the active runtime checkout as the explicit target for source edits, git diff, and server launches. Keep the campaign checkout only for orchestrator bookkeeping.

Give the Integrator disaggregated measurement instructions.
The Integrator must measure the combined result here. However, build_perf_optimize_prompts() adds DISAGG_CAMPAIGN to the benchmarker, analyzer, optimizer, evaluator, and QA prompts, but not the Integrator prompt. The Integrator therefore receives SERVER_LIFECYCLE and can try to use the regular server path during a disaggregated parallel batch.
Add an Integrator-compatible disaggregated override. It must use the harness workflow for integration measurements.
