Priority: ➖ Normal Estimated code review effort: 4 (Complex) | ~60 minutes Unblocks: 3 PRs Merge Risk: 🔵 Low · up to The current Dynamo integration remains compatible, but its next AISimulate dependency update must add the new optional field to avoid a compile failure. 🚥 Pre-merge checks | ✅ 3 | ❌ 5❌ Failed checks (5 warnings)

Full details: Cross-Layer ContractExplanation The new agentic identity field is dropped at the reporting boundary. Resolution Trace Full details: Modeling And Data EvidenceExplanation The PR changes replay selection and timing behavior, including agentic admission, equal-time event ordering, and predicted timing paths. The diff adds regression tests that compare continuous and stepped runs and compare reversed feedback order, but these are self-consistency checks. They do not provide a base-versus-head result, an independent oracle, a held-out comparison, or an explained golden diff. The authoritative diff adds no JSON, JSONL, CSV, snapshot, or golden artifact. The lifecycle report exposes only an event count and digest, not a machine-readable before/after performance summary with anomaly checks. The PR description's test counts and claim that qualification JSON is identical are binary-only validation; the AIPerf link provides semantic provenance but not reproducible output evidence. Resolution Add a checked-in or attached machine-readable before/after evidence artifact for representative agentic workloads. Include exact inputs, baseline and PR outputs, report fields, timing differences, and anomaly checks. Document the command, revision, and environment needed to reproduce it. For the changed scheduling and timing behavior, also provide either an explained golden diff, an independent oracle such as a directly comparable reference implementation, or a held-out workload comparison. Full details: Compatibility BoundariesExplanation The PR introduces an unsynchronized Rust source-compatibility break. It adds the public Resolution Either preserve the Full details: Review EvidenceExplanation The description reports results and lists relevant boundary cases, including failed, canceled, rejected, delayed, background, cleanup, feedback-validation, and live-resumption coverage. It does not name the exact validation commands. It also does not explicitly distinguish local, fake-runner, parity, and production evidence. The reviewed diff changes no workflow files, and the description does not cite inactive nested workflows as hosted CI evidence. Resolution Update the validation section with the exact commands and results. Label each result as local, fake-runner, parity, production, or hosted CI evidence. State clearly which hosted checks ran for the reviewed head and exclude inactive nested workflows from the evidence. Full details: Description checkExplanation The description gives detailed context, review risks, behavioral changes, regression coverage, and CI evidence. However, it does not follow the required template structure and omits the required Codex reviewed commit for the stated medium risk. Modeling or data provenance and Tracking sections are also absent.

feedback application flow and reject any finite, non-negative feedback.at_ms
that is lower than the previously applied value, while preserving deterministic
Replay semantics and existing invalid-timing validation. Add a regression test
covering a batch with reversed timestamps.

- Around line 34-36: Propagate ReplayReport::agentic_lifecycle through the
ai-dynamo/dynamo offline adapter into the public Python report model, including
the corresponding serialized field and public exports. Update the exact-shape
integration test to assert the new field and preserve consistency across the
adapter, model, serialization, and tests.

at_ms. A later batch with a lowerat_msrecords a lower timestamp at a higher lifecycle ordinal, and releases dependents into the simulated past. Track the last applied feedback timestamp and reject a lower value.This repeats an earlier review comment on the same validation block.

Reviewed 7f6e7d6, including the feedback-batch correction and current main 8c4929d. Mixed valid/invalid feedback now fails before lifecycle effects are applied; both new regressions failed before the fix and pass afterward, with unchanged state on rejection and monotonic same-time recovery.
Validation: full local Rust package 1,373 passed / 1 existing ignore; formatting and whitespace checks passed. Exact-head Full CI attempt 2 completed successfully (53 successful jobs; release staging skipped as expected), and Fast CI, DCO, CODEOWNERS integrity, and CodeRabbit are green. All four review threads are resolved. No remaining actionable issue found in this PR. The future Dynamo pin update must include the documented agentic: None initializer adjustment.

Implements AIC-1890. Base: main; risk: medium.
Agentic replay applies runtime-owned feedback in graph-ordinal order, separates causal terminal from resource quiescence, and exposes state-preserving settled steps in aggregated and P/D runtimes. Request identity and a canonical lifecycle transcript travel across the workload/runtime boundary. Equal-time events and handoffs use stable semantic ordering; the first step settles zero-time scaling and worker startup while preserving the telemetry baseline.
Client lanes now count whole client plays. A successful play releases its lane after all authored requests finish, including delayed and background requests. Under the existing strict failure policy, undispatched work is skipped and the lane waits for all dispatched requests to become terminal. The next play can then submit while earlier server cleanup is pending. Quiescence still tracks P/D source holds, cancellation actions, play settlement, and final drain. Late cleanup cannot release a lane twice, and request completion does not flush reusable prefix-cache entries.
This boundary follows AIPerf's root-finished and no-outstanding-descendants tree condition. Final decode/observed failure is a client-terminal proxy: HTTP/SSE delivery and client teardown latency are not modeled. The existing strict failed-play policy is not full AIPerf error-policy parity.
Review order:

8c4929d3544938b5878430236dd861a7f5412237. Stack: main → #121 → #122 → #190. Conflict resolution preserves #184's idempotent canceled-handoff cleanup, #203's G3 counters/drain behavior, and the client-terminal lane boundary. The moved CLI guide and both sets of CLI tests are retained. CI workflow changes are inherited from main, with no CI changes in these PR diffs.Earlier validation on downstream stack head

At head
7f6e7d602d5a3965e8343aced7071c8caa7d91b4, feedback batches validate all causal terminals and prospective quiescence before applying any lifecycle effects.
