Explanation
The PR description names test and quality checks with results, including exact-head native tests, stack-tip workspace tests, Ruff, formatting, whitespace, and diff checks. It includes boundary validation for unsupported policies, runner capabilities, output preservation, and adapter scope. It distinguishes local/native results, fake fixtures, pinned-source parity review, and hosted CI status. It explicitly states that historical checks do not qualify as hosted CI evidence, so it does not cite inactive nested workflows as hosted CI evidence.
Full details: Description check
-
Explanation
The description is detailed, relevant, and covers the change, review scope, compatibility boundaries, test evidence, and risks. It uses equivalent headings instead of the repository template and omits explicit Tracking and Modeling or data provenance sections, but the missing content is non-critical because the scope is clearly documented.

Full details: Cross-Layer Contract
-
Explanation
The cross-layer contract remains incomplete. The new SDK
Workloadrow now documents both policies, default omission, profile requirements, andsupports_agentic_live_warmupatdocs/sweeper/sdk.md:219, but it does not state the offline--stack enginelimitation required for this public table. The recommendation path copies the policy inpython/aisimulate/src/aisimulate/recommend.py:735-736and feeds it intorecommendation_to_sweeperat:307-309, but the changed tests only cover direct schema/workload serialization and a manually constructed runner spec. No test verifies recommendation-to-ReplaySpecor runner-payload propagation. In addition,RunnerCapabilitiesis public (python/aisimulate/src/aisimulate/sweeper/__init__.py:56,206), but the new field is inserted before existingsupports_generic_speculationandsupports_tokenizationfields atpython/aisimulate/src/aisimulate/sweeper/replay.py:341-345; this shifts positional constructor arguments and contradicts the claimed compatibility preservation.Resolution
Add the offline
--stack enginelimitation to theagentic_warmup_policyrow indocs/sweeper/sdk.md. Add a recommendation-to-ReplaySpectest that configureslive_trajectory_v1and verifies the runner receives it. Movesupports_agentic_live_warmupafter the existingRunnerCapabilitiesfields so existing positional arguments retain their meaning, and add a regression test for that positional constructor order.
Full details: Modeling And Data Evidence
-
Explanation
The PR changes live trajectory selection and scheduling, including primer alignment, recycling, per-lane quotas, and frontier handoff in
crates/core/src/replay/loadgen/phase.rsanddriver.rs. It provides provenance through pinned AIPerf and InferenceX references (phase.rs:7-16,docs/replay/agentic/warmup.md:246-267). The validation remains binary-only local tests: the main live test uses aself-authoredfixture (phase.rs:889-900) and asserts an implementation-authored sequence (phase.rs:983-998). No changed file adds a golden diff, independent oracle output, held-out comparison, or machine-readable before/after summary with anomaly checks. The documentation explicitly limits this to native functional qualification and excludes full AgentX parity (docs/replay/agentic/warmup.md:228-236). The prior failure is therefore unresolved.Resolution
Add a deterministic, checked-in evidence run for a fixed fixture and pinned reference. Emit machine-readable before/after traces for the default and live policies, including inputs, seed, source revision, request selections, timestamps, quotas, frontier, cursor, and failure/cohort status. Compare the traces with an explained diff or independent oracle. Add anomaly checks for request counts, ordering, timer preservation, and frontier handoff. Record the exact command and results in the replay qualification record. Test pass counts alone are not sufficient.
Full details: Compatibility Boundaries
-
Explanation
The PR still breaks the public positional constructor contract for
RunnerCapabilities. Inpython/aisimulate/src/aisimulate/sweeper/replay.py:342-345,supports_agentic_live_warmupis inserted before the existingsupports_generic_speculationandsupports_tokenizationfields. Existing positional callers therefore bind later values to the wrong fields. The PR adds no positional regression test for those two fields, and no version change documents the break.Resolution
Move
supports_agentic_live_warmupaftersupports_tokenization. Add a regression test that constructsRunnerCapabilitiespositionally with explicit values forsupports_generic_speculationandsupports_tokenization, then verifies both attributes retain those values.

Fixed the contracts-shard failures in e744278 and integrated the latest #463 fixes in current head dff05a0:
Validation on the exact PR native extension: 314 tests passed in forward order and 314 in reverse order, including all five previously failing hosted cases. After integrating #463, the six-file combined regression passed 1,044 tests. Ruff/format/diff checks passed. CI gates were not weakened. There are currently no inline review threads on this PR to resolve; CodeRabbit skipped this non-default-base PR rather than issuing an approval. |

LGTM, approving this layer. The approval assumes #463's two issues are fixed and the stacked Full CI goes green; it's currently red only via #463's E0063.
What I checked:
- Primers: globally aligned, concurrent, and outside the per-lane quota.
- Warmup budget: exactly ten live admissions per lane, recorded before the next pick in the same
pop_readybatch. Over-quota ready sessions are deferred and restored rather than dropped, andnext_ready_time_msignores them. - Accounting: warmup traffic is excluded from
issued_requests/responses untilstart_msis set, and from trajectory/outcome cohorts viapreparation_only. Aborted live warmup marks everything preparation-only. - Handoff: fresh plays are prepared before
reset_measurementsand committed after it, so a failed reset stays retryable.ready_sessionsis rebuilt only for Ready nodes, with no in-flight work at the barrier. The same-time budget stays finite during warmup and is reset at profile activation.
This also fits the replay liveness contract: unfinished requests keep a concrete wakeup (frontier timers, dependency release or the control time), and nothing spins at the same timestamp. Live warmup is opt-in, and runners must advertise support. The config field is documented on the workloads page, and the AIPerf-derived code carries notices in both copies.
One design question inline.

Re-approving on fa5ed65. The new warmup.md paragraph answers my handoff-idle question: one global minimum, matching the pinned reference's _handoff_replay_offset_ms / _profiling_phase_t0_offset_ms with default spread phase starts, with burst re-anchoring explicitly not modeled. I confirmed this PR's own code delta is unchanged since my last review; only that doc paragraph and the carried #463 fixes are new. This still assumes Full CI finishes green.

Review comments at @crates/core/src/replay/loadgen/phase.rs:
- Around line 284-303: Update AgenticPreparation::with_policy and every call
site, including build_agentic_driver, to accept and pass speedup; validate it is
finite and positive. In the primer_times_ms calculation, divide the source-clock
lead by speedup before applying the nonnegative and primer_idle_cap_ms limits,
and add a non-unit-speedup assertion covering next_ready_time_ms().
Review comments at @crates/core/src/replay/loadgen/snapshot.rs:
- Around line 35-53: Add a migration note for the next aisimulate-core release
documenting the public AgenticSnapshotOptions API break: callers must replace
seed-only struct literals with AgenticSnapshotOptions::seeded(seed), and account
for the removed Copy behavior. Ensure the release version metadata records this
breaking change before publication.
Review comments at @docs/sweeper/sdk.md:
- Around line 227-230: Update the SDK Workload documentation by adding the
agentic_warmup_policy field row with its accepted policies, default,
requirements, serialization behavior, and reference link. Revise the following
profile paragraph to distinguish repeated_prefixes from live_trajectory_v1,
describe seed-only sampling and exact-cut imports accurately, and require
supports_agentic_live_warmup for live_trajectory_v1 alongside
supports_agentic_profile.

The replay adapter constructs
RunnerCapabilitiesbut does not pass the newsupports_agentic_live_warmupcapability, so Dynamo will retain the default unsupported status. [::ai-dynamo/dynamo::components/src/dynamo/replay/simulation.py:66-108] -
The adapter forwards only
agentic_snapshot,agentic_warmup, andagentic_profile;agentic_warmup_policyis omitted, solive_trajectory_v1cannot reach Dynamo’srun_trace_replayAPI.

## Agentic Load Controls
### Warmup
Successful profiles exclude preparation-only requests and retired plays from
counts and latency distributions. Active partially warmed plays retain their
identities and get a formal measurement origin at the barrier. An aborted live
warmup has an empty formal cohort; its request ledger remains in
`agentic_phases`. See [live trajectory warmup](agentic/warmup.md#live-trajectory-policy)
for qualification boundaries. Unsupported CLI stacks are rejected before
`--overwrite` prepares the output directory; external SDK adapters must
explicitly advertise `supports_agentic_live_warmup` and forward the policy.

Summary
Stacked on #463. Add opt-in
traffic.load.agentic_warmup_policy: live_trajectory_v1for continuous AgentX profiles; the default repeated-prefix policy remains unchanged.Stack and review focus
Parent #463 and FPM identity #476 are merged. This PR now targets main and preserves main
918cb5a24c4ddc42a0ba624b4f70c826aef4e736, including #523 catalog updates. Current head:3fc7094d7011367cca1ce1ae97b9adde695b905f.The restack is a signed, history-preserving merge without force-push. Its full tree matched the independently computed old-parent-relative integration; main additions were preserved. The subsequent small follow-up fixes non-unit primer speedup and documentation. Review order remains #465 → #492; #492 retains the separate causal-handoff correction. No closed #464 streaming patch or private frontend delay is included.
Review fixes (October 19)
October 20 review follow-up
Validation
embed-pythonnative built and immutable module identity verified; 895 focused Python tests passed on this head.cargo test --workspace --locked --offline2,166 passed (2,005 core, 158 integration, 3 doctests), one existing R17 artifact-dependent test ignored; excluded public API 16 passed. This is explicitly stack-tip workspace coverage, not a separate feat: advance AgentX trajectories during opt-in live warmup #465 workspace run.ffe706e0passed 895 focused + 390 frozen-golden cases, with goldens unchanged. The final loadgen/doc-only follow-up does not touch performance-model math/data or goldens; that golden run is prior-head evidence, not a new-head rerun.Advisory retest boundary
The earlier hosted CPU-predictor advisory flagged one cold unseen-query case (+10.28%). A fixed-original-SHA, pinned-CPU local retest used the unchanged 64-case/5-round protocol and thresholds: 128 comparisons, two different cold regressions, 66 noisy comparisons, no invalid results. The original point exceeded the threshold in 3/5 rounds and was classified noisy. This is not a clean pass or proof of a flake; the new-head hosted comparison remains the next qualification step. No predictor math or benchmark-threshold code was changed to suppress the result.
Boundaries
Initially supported by offline
enginewith continuousagentic_profile. External adapters must explicitly advertise live-warmup support. This is workload/phase fidelity, not GPU accuracy or full HTTP/tokenizer parity; AgentX tokenization remains unsupported as on main. No timing estimators, golden values or GPU workloads are changed.
