Resolve driver imports and the CLI parser relocation while preserving snapshot identity/timing and all tests from both branches. Adapt the public API import to the renamed Rust crate and give the snapshot CLI test a real trace for the new resource preflight.
Resolve Rust, CLI, release, and CI conflicts while preserving the prepared warmup/P-D contract and upstream resource and batch reporting. Retain preparation admission evidence until the barrier and measure bounded profile reports from the profile epoch. Cover summary/detailed report parity, bounded reclamation, and canonical model identities.
Preserve warmup, barrier, offline P/D, and bounded profile reporting while merging main 3bfdbf8, including the squashed AIC-1811 prerequisite. Retain both sides of the capability/API/test additions and update the fixed-timing regression for the removed external decode 1 ms floor. Signed-off-by: Harry Lee <harrli@nvidia.com>

| Layer / File(s) | Summary |
|---|---|
Profile contracts and source selection crates/core/src/replay/loadgen/* |
The load-generation layer adds profile options, report types, internal state, deadline calculation, public exports, and explicit source-play selection. |
Committed request propagation crates/core/src/engine/..., crates/core/src/replay/components/engine.rs |
Schedulers propagate committed request IDs into replay pending-pass state. Tests cover prefill, cached work, queued work, cancellation, and speculative retraction. |
Workload driver profile lifecycle crates/core/src/replay/loadgen/driver.rs |
The workload driver enables profiles, tracks deadlines, recycles lanes, shifts idle timers, applies cutoff behavior, and records profile metrics. |
Python configuration and execution integration python/aisimulate/..., crates/core/src/python.rs |
Python and Rust entry points validate and propagate profiles through runtime configuration, workloads, and replay metadata. |
Replay runtime deadlines and cancellation crates/core/src/replay/agg.rs, crates/core/src/replay/disagg.rs, crates/core/src/replay/components/admission.rs |
Replay runtimes advance profiles, schedule deadlines, cancel pending requests, and report canceled or unsettled work. |
Profile and bounded reporting crates/core/src/replay/report*, crates/tests/public-api/src/lib.rs |
Reports retain profile evidence and calculate observation duration, successful-request throughput, and resource accounting. |
Configuration validation and execution coverage tests/*, crates/core/src/engine/scheduler/*/tests.rs, crates/core/src/replay/disagg_tests.rs |
Tests cover configuration, propagation, runtime execution, backend combinations, cutoff behavior, resource supervision, and committed-pass tracking. |
Profile usage documentation and example docs/*, examples/cli/*, python/aisimulate/src/aisimulate/cli_args.py |
Documentation and the CLI example describe profile settings, supported paths, lane recycling, deadlines, cancellation, and reporting. |

Fixed the fully cached zero-output settlement risk in c362aeb, including the concern in the current review's global risk summary. SGLang now records committed prefill ownership only for requests whose aligned native FPM entry actually computed input tokens. A fully cached zero-output request is excluded, while cold/chunked prefill remains committed even if it emits no token. The new native regression checks a mixed cached/cold batch with real cache-hit and forward-token counters. A replay-level regression for both vLLM and SGLang seeds the prefix cache, launches cached-zero and cold-zero requests in one batch, then cancels at 35 ms: two client cancellations, zero client in-flight, and exactly one unsettled server request. The old SGLang implementation incorrectly reported two. This tests the profile cancellation/reporting path, not only the scheduler field. Full Rust core library on c362aeb: 1661 passed, 1 existing ignored, 0 failed; formatting and whitespace checks pass. #306 integrates this commit. Current-head hosted CI and CodeRabbit checks are still required; previous-head green results are historical. |

This commit changes documentation only: all core source is byte-identical to c362aeb (1661 passed, 1 existing ignored). Current-head CI/review remain separate checks. Required Evidence/Tracking fields are included in the PR description. |

Review follow-through is complete at 2a33095. The fixes and thread-specific replies cover cutoff/quiescence, positional capability compatibility, actual committed-work cancellation (including SGLang cached-zero requests), static reporting epochs and supervised duration admission. All seven review threads are resolved. The complete quickstart now uses two whole Weka plays, two lanes, actual 64-token source blocks and a 4 GB supervised budget. Its exact YAML runs for 3600 simulated seconds through the standalone engine: 219 successful requests, zero canceled/unsettled, with observed cache reuse; the documented 600-second override also passes. #306 includes this head and qualifies duration plus native Dynamo routing using an installed matching wheel pair, without #15149 or local overrides. Artifact provenance and source equivalence are recorded in both PR descriptions. Both current-head Fast checks and Full CI pass (52 successful jobs, two expected skips; exact RUN_SHA verified). Complete CodeRabbit review is Minimal with 8/8 pre-merge checks. Its initial Cross-Layer Contract INCONCLUSIVE result was rerun on the same head and passed; no check was bypassed. Required CODEOWNER/domain approval and main freshness remain merge gates; this PR is not merged. |

Why and what changed
Finite snapshot replay stops after its initial plays. Add opt-in
traffic.load.agentic_profileacross native, Python, CLI and Sweeper paths to sustain AgentX lanes for a requested duration. It recycles completed lanes with fresh play identities, applies idle guards, stops admission at the cutoff, allows response grace and acknowledges client cancellation. Unfinished server work remains visible.Defaults are a 3,600-second window, 300-second tree / 10-second global idle caps, 30-second response grace and 10-second cancellation drain. Finite replay remains the default. Reports separate the admission window from successful-response observations, including responses received during grace. The quickstart includes complete YAML and a 600-second override.
Review map and corrected boundaries
Risk is high: review profile loadgen lifecycle, aggregated/P-D cancellation and bounded reporting. Delayed/background descendants, repeated lanes, corpus wrap, zero-time loops, idle compression, queue cancellation and actual committed batch ownership are covered.

The source pair uses AISimulate production commit
240aff04bc45936eac754608ced5ce0989096022(containing this duration work and #306's hooks), built with the existing Dynamo distributions. There is no new package, bundled policy implementation or local override. The combined quickstart records the tested immutable Dynamo revision and complete duration+routing commands. The cleana095ab572csource pair passes 38 installed CLI tests and both 600/3,600-second quickstart examples. Current consumer verification is tracked in #15240, which remains open awaiting its complete CI and required review. A source build is not a published matching release.Delivery order and feature acceptance
The requested order is Dynamo #15240 → revalidate AISimulate against the merged Dynamo commit → AISimulate #307 → #306. The actual AISimulate base stack stays
main ← #307 ← #306.Dynamo #15240 can build first using publicly available immutable AISimulate source
240aff04; the AISimulate PRs do not need to have merged for that fetch/build. This temporarily leaves Dynamo pinned to unmerged AISimulate source, to be advanced after the AISimulate merge/release. There is no reverse core dependency or local override.Current conversation-routing acceptance uses Dynamo feature commit
a095ab572c, not Dynamo main. AISimulate's own passing CI does not establish that the full feature works with merged Dynamo. Rebuild/install the matching pair and rerun the real CLI/quickstart against the actual Dynamo merge commit before declaring this delivery complete. Published matching packages are a separate requirement; the current documented installation builds existing wheels from source.Modeling and provenance
Independent implementation on AISimulate's dependency graph and virtual event loop. Behavioral reference:

Functional qualification does not establish GPU accuracy or complete live AgentX parity. AIC-1896/1818 joint acceptance remains open; lifecycle evidence grows with issued work.
