Why and what changed

Part of #475. Hybrid-attention models such as GLM-5.3-Flash keep per-request state in KDA or Mamba layers next to their attention layers. Stage 1 (#565) sends such model configurations to the runtime probe, and Stage 2 (#657, now on main) adds state cache groups to the FPM profile. Before this PR, the probe import accepted only full and sliding-window attention groups, so onboard import-observations refused every hybrid model. With this PR, onboard probe-runtime on vLLM 0.33.0 records every cache group of a hybrid model, and the import turns that record into a grouped FPM profile. Self-service onboarding then takes the cache geometry of a model that intake does not know from the probe, instead of refusing the model.

This PR first targeted vLLM 0.31.0. Dynamo moves to vLLM 0.33, so vLLM 0.31.0 is no longer the target, and the branch now targets exactly vLLM 0.33.0 with the Dynamo scheduler file of the release/1.7.0 branch. The rework adds new commits on top of the reviewed head 0c968207c and merges main five times. A reviewer who approved the vLLM 0.31.0 version can read git diff 0c968207c..HEAD and look again at these parts: the new probe bundle, the version gate for hybrid evidence, the kernel-block views, the prefill checkpoint block and its two profile fields, the loaded configuration commit, the live fixture and its test, and the merges with main in the observer and import code.

What the branch does now:

• Probe bundle. A bundled vLLM 0.33.0 instrumentation bundle replaces the vLLM 0.31.0 bundle of the earlier head: vllm-0.33.0.json, instrumentation/vllm_033.py and the source notes instrumentation/vllm-0.33.0.md. vllm-0.31.0.json, vllm_031.py and vllm-0.31.0.md are gone. The manifest pins 35 files by SHA-256: 34 vLLM files of tag v0.33.0 (commit 4ba787ec) and one Dynamo file. bundled_instrumentation now serves vLLM 0.27.0 and 0.33.0. The bundle serves every model on the probe route, a plain attention model as well as a hybrid model. GLM-5.3-Flash probes add --language-model-only, so the probe measures the same deployment as collection.
• Hybrid evidence only from exactly vLLM 0.33.0. A record holds hybrid evidence when a cache group holds layer_specs. The bundled observer writes this evidence only when its adapter version is 0.33.0. The import refuses a record with hybrid evidence whose runtime version is not exactly 0.33.0, also when it comes from a campaign-local bundle. The diagnostic is hybrid cache evidence requires vLLM 0.33.0; the record names vLLM <version>. A record without hybrid evidence imports as before for every version. Main now accepts a final patch release of vLLM 0.32 or 0.33 on the collection route when the audited files are unchanged. Such a patch release serves plain models only: no bundle exists for it, and the import refuses hybrid evidence from it.
• Cache spec classes. One class table maps vLLM cache spec classes to FPM cache kinds. MambaSpec and CircularBufferSpec become state groups. A UniformTypeKVCacheSpecs group takes the one kind of its inner specs. KpoolTailSpec does not exist in vLLM 0.33.0, and its entries are gone. RSWASpec, HiSparse placement and any other unknown class are reported as unsupported.
• Kernel-block views. vLLM 0.33.0 binds the layers of an attention group whose backend sets its own kernel block to a view in kernel blocks (v1/worker/utils.py:397-430). The observer records kernel_block_size and kernel_block_stride of each attention group, and each view of a hybrid record holds its kernel_block_stride. A view with stride 0 must hold num_blocks * (block_size // kernel_block) kernel blocks. A view with a positive stride must hold (num_blocks - 1) * kernel_block_stride + block_size // kernel_block kernel blocks. The storage_block_size rule of the earlier head is gone, because vLLM 0.33.0 specs have no such field.
• One prefill checkpoint block of a state group. With the FlashKDA prefill backend, vLLM 0.33.0 gives a KDA layer one prefill checkpoint block with an alignment of 16 tokens. With the Triton backend, it gives none and no alignment (kda.py:168-176, kda_checkpoint.py:9-10). The observer records num_prefill_checkpoint_blocks and prefill_checkpoint_alignment of every Mamba group. The import accepts a count of 1 with a positive alignment, or a count of 0 with no alignment, and refuses every other combination. The earlier head refused every checkpoint block. The steady blocks_per_request of a state group stays 1.
• Two profile fields in Python and Rust. FpmCacheGroup gains the optional fields prefill_checkpoint_blocks (0 or 1, state groups only) and prefill_checkpoint_alignment (positive, needs a count of 1), in fpm_profile.py and in resources.rs, with the same texts in the same order. An absent field is not serialized, so a profile without the fields loads and saves to the same bytes as before. The import writes the count for every Mamba group and the alignment for a group with one checkpoint block. A probe claim that states one of the fields must equal the measured value. Sizing and replay do not read the fields yet.
• Loaded configuration commit. For a model that vLLM loads by its Hub ID, the observer takes the commit from the instance dictionary of the loaded configuration only. A configuration that forwards attribute reads to a nested text configuration can report the commit of another configuration. If the loaded configuration holds no 40-character commit, the observer takes the commit of the pinned revision whose snapshot holds the cached config.json. An unpinned revision gives no snapshot lookup, and the configuration hash stays unknown. The transformers 5.20.2 of the live runs stores no _commit_hash.
• Other checks of the import. The rules of the earlier head stay, now on the vLLM 0.33.0 layout: pages, allocation and alias ownership, the views of a Mamba layer against its state tensors, the block sizes and hash block size of each scheduler, the Mamba cache mode, and the prefix-caching values of each phase against the resolved cache configuration. The import also checks the kv_cache_max_concurrency of each scheduler against the blocks that vLLM counts for one request at max_model_len in all groups, except in a layout with a sliding-window group. The runner refuses a backend policy that sets --mamba-cache-mode for a run with memory observation.
• Collection and onboarding. Formal collection bindings, profile verification and onboarding finalization compare the prefix-caching values and the cache group geometry of every phase with the accepted probe. The profile review keeps the line of main for every grouped draft, and adds State groups hold a fixed block count per request. only for a draft with a state group. The probe guidance for a hybrid configuration names vLLM 0.33.0.
• Live fixture and test. tests/unit/collector/fixtures/glm53flash_vllm_0330_probe/ holds the prefill phase of a live GLM-5.3-Flash probe on vLLM 0.33.0. test_import_accepts_the_live_glm53flash_record_of_vllm_0330 imports it and checks the result. The hand-made GLM-5.3-Flash test records now use the cache geometry of the live record.
• Rust. The grouped KV forward error names the fixed state bytes of one request (GroupedKvPool::fixed_request_bytes).
• Docs. The FPM self-service guide, docs/perf-model/memory.md and the instrumentation notes describe the vLLM 0.33.0 import and link the source notes.

What main brought in through the merges: the vLLM 0.32.0 and 0.33.0 plain-model memory observation and the reader of layer-strided allocation records (#765), the patch-release rule of the collection route (#788), sliding-window prefix retention for the DeepSeek V4 replay (#776), a CI check of the provenance of bundled model configurations (#547), and the charge of state cache groups once for each grouped pool (#801). The merges with #765 and #788 had conflicts in the observer, the import and the docs. In each conflict the plain-model code of main stays, and the hybrid additions sit on top of it. The merge with #801 had no text conflict, but both sides change crates/core/src/engine/kv_manager/grouped.rs. Main now keeps the state groups in one stored state charge, so GroupedKvPool::fixed_request_bytes reads that charge, and one test literal of main gets the two new profile fields. The method returns the same value as before for every kind of pool, and the hot functions of the pool are those of main. The message of each merge commit lists its conflicts. The fifth merge takes main at 6c2e6b128, so that the diff of #700 holds only the change of #700. It brought the paired A/F performance models and the native AFD replay (#585), the hash of the semantic deployment inputs in the FPM execution evidence (#747), state_cache with FPM profiles that record runtime memory (#800), a cgroup memory reading without inactive page cache (#816) and two changes of the MTP scheduler pass (#812, #813). It had no conflict. Two files changed on both sides and merged without a text conflict: crates/core/src/engine/scheduler/vllm/core.rs and python/aisimulate/tests/unit/sdk/test_fpm_profile.py. Every AFD entry point of main refuses a vLLM backend, an FPM profile and a state cache, so nothing of it reaches the grouped vLLM scheduler or the FPM profile fields of this PR.

The users of this change are people who onboard hybrid-attention models through FPM self-service onboarding.

Review map

• Risk level: medium
• Start with, in this order:
  1. python/aisimulate/collector/fpm_forward/runtime/vllm-0.33.0.json and runtime/instrumentation/vllm-0.33.0.md: what the bundle pins and why.
  2. runtime/instrumentation/observer.py (_layer_views, _loaded_config), runtime/instrumentation/vllm_033.py and runtime/fpm_memory_observer.py (HYBRID_EVIDENCE_VERSION, cache_groups, scheduler_memory): what the probe records.

  9. docs/perf-model/fpm-self-service/implementation.md, README.md and docs/perf-model/memory.md.
• Public or serialized contract changed: yes.
  • vLLM 0.33.0 runtime observation records carry new keys. Cache groups add kind, layer_specs and state, and the state evidence of a Mamba group adds prefill_checkpoint_alignment next to num_prefill_checkpoint_blocks. Allocations add layers and layer_stride. Each layer view adds kernel_block_stride, and each attention_groups entry holds kernel_block_size and kernel_block_stride. Scheduler records add the block sizes, the Mamba cache mode and the startup capacity. Records add prefix_caching. The schema name aisimulate-runtime-observation/v1 stays, and every new key is additive.
  • The FPM cache group gains the optional fields prefill_checkpoint_blocks and prefill_checkpoint_alignment, in Python, in Rust and in the JSON Schema of the cache group. Rust reads cache groups with deny_unknown_fields, so an older AISimulate does not load a profile that holds the new fields.
  • A vLLM 0.33.0 import adds prefix_caching and phase_geometry_differences to the runtime_memory provenance.
  • New diagnostics, among others:
    • hybrid cache evidence requires vLLM 0.33.0; the record names vLLM <version>
    • runtime state cache group lacks prefill checkpoint evidence: <layers>
    • mamba prefill checkpoint blocks must be 0 or 1: <layers>
    • mamba prefill checkpoint evidence is inconsistent: <layers>
    • kernel tensor block coverage contradicts pool block geometry
    • layer view kernel block contradicts its cache spec: <layer>
    • <scheduler> lacks a positive kv_cache_max_concurrency
    • <scheduler> records kv_cache_max_concurrency <value>, which gives <n> blocks per request, but its cache groups reserve <m>
    • runtime observation requires complete prefix-caching evidence
    • runtime prefix-caching evidence contradicts the resolved cache settings
    • runtime prefix-caching evidence contradicts the scheduler block sizes
    • backend policy cannot select the Mamba cache mode for runtime memory observation
    • <phase>: runtime prefix-caching settings differ from the accepted probe
    • <phase>: runtime cache group geometry differs from the accepted probe
  • The diagnostic mamba prefill checkpoint blocks are not modeled: <layers> of the earlier head is gone.
• Feature Support Matrix: unaffected
• Compatibility or rollback concern: the instrumentation files change, so the bundle hash changes for every runtime version, vLLM 0.27.0 included. A campaign that planned or accepted a probe before this change must probe again, as after every earlier change to these files. Records of vLLM 0.27.0 and 0.28.0 keep their fields and their import results. The vLLM 0.27.0 memory path keeps its version pin and refuses state groups. The probe route takes the commit of a remotely loaded configuration by the rule above for every bundle version.

Evidence

• Tests: at fc1dec685. From python/aisimulate, .venv/bin/python -m pytest -q tests/unit tests/golden -n 4 --timeout=180 passed 15,117 tests with 32 skipped and 2 failures. From the repository root, PYTHONPATH=$PWD python/aisimulate/.venv/bin/python -m pytest -q -c pytest.ini tests -n 4 --ignore=tests/test_ci_workflow_contracts.py passed 5,980 tests with 7 skipped and 7 failures. All 9 failures are local and also fail with the code of main on the same machine: 7 because the module collector is not importable in the local environment (2 in test_support_cli.py, 4 in test_fpm_profile_workflow.py, 1 in test_fpm_grouped_workflow.py) and 2 in test_ci_qualification.py with baseline_source_sha does not resolve to a commit. tests/test_ci_workflow_contracts.py has one more local failure on this machine (Python 3.13.3), also on main. cargo test --locked -p aisim-core passed 3,266 tests with 0 failed and 3 ignored, and cargo fmt --all -- --check passed. The documented ruff check and ruff format --check pass (1,217 files). scripts/ci/check_copyright.py (1,779 files), check_packaged_legal_files.py, check_bundled_configs.py (128 configurations) and check_documentation_links.py (86 Markdown files) pass. No golden file changed. The head 7a88f3318 adds the merge of main at 6c2e6b128. A local merge with the same tree passed the package suite (15,182 tests, the same 2 failures), the root suite (6,126 tests, the same 7 failures), cargo test --locked -p aisim-core (0 failed) and cargo fmt --all -- --check. At 7a88f3318, ruff check and ruff format --check pass (1,215 files), and so do check_copyright.py (1,800 files), check_packaged_legal_files.py, check_bundled_configs.py (128 configurations) and check_documentation_links.py (87 Markdown files).
• Fast CI: passed at 1c8fa60c1.
• Full CI: passed at 1c8fa60c1. Every job of the run passed, and the Stage Application Wheel job was skipped. The build job of the separate GitHub Pages workflow passes on this head.
• CodeRabbit reviewed commit: fc1dec685, with no inline finding. Seven of its eight pre-merge checks passed. The Cross-Layer Contract check gave one warning: the import records kv_cache_size_tokens without a check, and it skips the kv_cache_max_concurrency check for a layout with a sliding-window group. This description names both, the first under the known limits and the second in the list of the import checks. Neither value decides a number of the profile.
• Codex reviewed commit: fc1dec685, with no findings (a local codex exec review of the branch against main, codex-cli 0.167.0, gpt-6-astra, reasoning effort max; the banner of the run shows sandbox: danger-full-access). An earlier round at 011dd8de7 found one P2: the hash block check of the import skipped the vLLM 0.33.0 start rule for a scheduler with a single cache group. 02885ca83 adds the rule with tests for both sides, and the rounds at 34a356dc1 and fc1dec685 found nothing.
• Live probe: one GB300 node with 4 GPUs, the stock vLLM 0.33.0 arm64 image (vllm 0.33.0, commit g4ba787ec9, torch 2.14.0+cu130, transformers 5.20.2, flashinfer 0.7.2.post1), and the Dynamo build ai-dynamo 1.7.0.dev20261109 mounted into the container. Before the GPU runs, all 35 pinned files of the bundle matched the installed runtime, by the check of the bundle and by an independent sha256sum loop. onboard probe-runtime ran three times at TP 4 with the bundled vLLM 0.33.0 bundle, and onboard import-observations returned status: complete with no diagnostics for each run:
  • GLM-5.3-Flash with a model folder (17 min 13 s of GPU time).
  • GLM-5.3-Flash with the Hub ID zai-org/GLM-5.3-Flash and the pinned revision 04c4e9e95c5da8862dced7e5056455116f83a7e0 (14 min 29 s). Every record resolves model_config_sha256 bb8f01c4… through the snapshot of the pinned revision, with no unresolved field.
  • MiniMax-M2.7 as a plain model (11 min 44 s): one FullAttentionSpec group of 62 layers with a 16-token block, layout LBHNC, 203,368 blocks and a concurrency of 397.203125 (= 203,368 / 512).
  • GPU time in total: 44 min 46 s. This includes one attempt of 1 min 20 s that stopped before any engine started, because of a PATH error in the job script.
• Observed values of the GLM-5.3-Flash record (both GLM runs give the same cache groups and runtime memory):
  • Layout BLHNC. Six groups, all UniformTypeKVCacheSpecs in the workers, in this order: 4 KDA groups of 9, 9, 8 and 8 layers, the attention group of 22 layers (11 indexer and 11 MLA latent layers), and the tail group of 11 rings. The imported profile has 5 state groups and 1 attention group.
  • Block size 2,176 tokens in every group except the tail group (4 tokens). Every group page is 13,516,800 bytes. The pool has 13,697 blocks, and kv_cache_bytes is 185,126,092,800 (= 13,696 × 13,516,800, the null block excluded).
  • Each of the 4 KDA groups holds 1 prefill checkpoint block with alignment 16, the values that only FlashKDA gives. No record names the KDA backend.
  • Prefix caching on, Mamba cache mode align, hash block size 2,176 tokens. The startup concurrency is 27.67070707070707 = 13,697 / 495, with 495 = 482 attention blocks + 1 tail block + 4 × 3 KDA blocks.
  • The model runner is the V2 GPUModelRunner with kernel block sizes [2176, 2176, 2176, 2176, 2176, 4]. The indexer view has shape [43827217, 32, 132], a kernel block of 128 tokens and a kernel block stride of 3,200: (13,697 − 1) × 3,200 + 2,176 / 128 = 43,827,217.
  • The workers record mamba_block_size 2,176, and the scheduler records 16, with block_size 2,176 in both. The multiprocess executor of this TP 4 run aligns the block size only in the worker processes. No import rule and no profile value reads the scheduler value.
• Dynamo facts: the bundle pins the SHA-256 of dynamo/vllm/instrumented_scheduler.py (2509d616…aaee), which is the file of commit 9abd2ef0d908c4bb323e1b8956ea76a5772a1d41 on release/1.7.0. Dynamo has no 1.7.0 release yet, and PyPI has no 1.7.0 release candidate. The live runs used the nightly build ai-dynamo 1.7.0.dev20261109, which carries that file. The main branch of Dynamo has already changed the file, and the nightly build 1.7.0.dev20261110 has another hash (93d999fd…). So a cherry-pick of that change into the release branch would need a new hash in the bundle. A runtime with another scheduler file leaves the evidence unresolved.
• An independent review of the whole branch at 18ebfbef8 checked these points, and a second review checked the changes that followed:
  • Plain models compared with main: 78 cases ran on the code of main and of the branch. 66 are byte-identical. 12 differ only in the refusal text for a hand-edited invalid record that a real vLLM 0.27.0 or 0.28.0 probe cannot write, and both sides refuse all 12. The test suite of main also passes on the code of the branch, except 17 tests that the branch changes on purpose and the 2 local failures. The profile review line of a draft without a state group is byte-identical to main.
  • Closed hybrid path: hybrid records under vLLM 0.31.0, 0.32.0, 0.33.1, 0.33.0.post1, 0.33 and 0.34.0 are all refused, and 0.33.0 imports. Of 55 edits of the live fixture, 46 are refused. The other 9 are 7 edits of keys that no import code reads and 2 valid variants.
  • Python and Rust readers: 24 combinations of kind, count and alignment give 0 disagreements between the Python validator and the Rust rule.
  • Live import: validate_observations on the raw evidence of all three live runs gives complete for both phases, and the resources equal the profile drafts of the cluster import.
  • Source: 215 line citations and 34 file hashes of vllm-0.33.0.json were checked against the tag and the Dynamo commit. 11 wrong or shifted citations were corrected, and the second review found all 11 right.
  • Privacy: two scans of the added lines (24,879 lines in the second) and of every string of the fixture found no user name, home or cluster path, host name, e-mail address or secret.
• Negative or boundary cases:
  • A hybrid record of any version other than exactly 0.33.0 is refused, also from a campaign-local bundle that pins vLLM 0.33.1 or 0.28.0. A plain 0.33.1 record imports as before.
  • A Mamba group without its checkpoint count or alignment key is refused. A count other than 0 or 1, a bool or float count, a count of 1 without a positive alignment, and a count of 0 with an alignment are refused.
  • A view without kernel_block_stride, a view whose block axis does not cover its kernel blocks, and an indexer AttentionGroup with a negative stride are refused or left unresolved.
  • A kv_cache_max_concurrency that is missing, 0, negative, a bool, infinite or inconsistent with the cache groups is refused.
  • RSWASpec as the inner spec of a uniform group is refused as an unsupported runtime cache spec.
  • A scheduler with a single cache group, prefix caching on and a prefix_match_unit other than its block size is refused, because vLLM 0.33.0 does not start with it (v1/core/kv_cache_utils.py:840-858). An external review found this gap, and the single-group case now applies the rule.
  • Each refusal that the branch adds and that a record can reach has its own test. Each of 8 such refusals was disabled in turn, and exactly its test failed.
  • A layer view refusal that could never fire is removed, with a proof and a fuzz run of 400,000 inputs on the old code that never reached it.
• Expected-value derivation: the live GLM-5.3-Flash record leaves 13,696 usable pool blocks of 13,516,800 bytes. A request at the 1,048,576-token context needs 482 attention blocks of 2,176 tokens and one block in each of the 5 state groups: 487 blocks. test_plan_admits_the_imported_glm_draft_at_its_observed_capacity pins request_peak_cache_bytes = 487 × 13,516,800 = 6,582,681,600 and total_kv_size_bytes = 13,696 × 13,516,800 through onboard plan.
• Before/after output: no prediction changes. The suites above include tests/golden and the Rust engine tests.

Modeling or data provenance

The fixture python/aisimulate/tests/unit/collector/fixtures/glm53flash_vllm_0330_probe/ is the prefill phase of the Hub-ID run above. It holds 15 files (678,683 bytes): observations.json, the launch manifest of the phase, the scheduler record and the 4 worker records of the phase, and the frozen bundle of that run (its manifest, fpm_memory_observer.py and the 6 files of instrumentation/). The index keeps only the prefill phase and its 5 observation artifacts. generator_request and resource_manifest are removed from the phase, because the one-phase import does not read them. For a public repository, the cluster paths are replaced by /models/... and /work/..., and the node name by node0000, with the same replacement in every file. The import reads these strings only for non-emptiness and for equality between files, and the one-phase import of the fixture gives the same cache groups and runtime memory as the import on the cluster. The fixture holds no weights, no tokenizer files and no token text. The frozen bundle copies keep the hashes that the records name, so pyproject.toml excludes the fixture folder from ruff. The bundle at the head differs from the frozen bundle only in its two notes files.

The vLLM source lines that the code, the notes and the docs cite come from tag v0.33.0. The Dynamo lines come from commit 9abd2ef0d908c4bb323e1b8956ea76a5772a1d41.

Known limits and follow-ups

• The replay does not yet model the prefill checkpoint block for vLLM 0.33.0. Grouped execution needs prefix_caching: false, and vLLM holds the checkpoint blocks only in align mode, so blocks_per_request: 1 is what vLLM holds in a run that replay accepts. The plan of a request also counts one block for each KDA group and no checkpoint block. The replay rules for vLLM 0.33.0 belong to a later change.
• The bundle hashes of vLLM 0.27.0 and 0.28.0 change on this branch, because bundle files change. A formal collection that was planned before the upgrade is refused by its pinned plan, and the campaign must plan again.
• onboard probe-runtime --execute for a version without a bundle answers runtime probe requires target-container version detection before execution when the detected version equals the requested one, instead of naming the missing bundle. This message is older than this branch, and the probe is refused in both cases.
• The attention precision rule of this branch differs from the rule of the next pull request in the stack (feat: collect GLM-5.3-Flash through FPM self-service onboarding on vLLM 0.33.0 #700). Here the declared attention precision must equal the observed model dtype, so the live GLM-5.3-Flash records declare bfloat16. The collection branch uses the checkpoint-native label (fp8 for an fp8 KV cache), and it carries its own fixture from a probe with that label.
• The rules cover more than the live evidence. SlidingWindowMLASpec, SinkFullAttentionSpec, HiddenStateCacheSpec, the Triton checkpoint case, Mamba mode none, the V1 runner and the uniprocess executor have unit tests only. The live evidence covers FullAttentionSpec, MambaSpec in uniform groups with FlashKDA, MLAAttentionSpec, CircularBufferSpec, align mode, the V2 runner and the multiprocess executor.
• The import records kv_cache_size_tokens but does not check it. It does not read attention_groups, raw_cache_config or kv_cache_layout, and the placement checks decide the layout. The import accepts a few hand-made inputs that no real runtime writes, such as an edited attention_groups entry or a checkpoint alignment other than 16. None of them changes a profile value that a real record gives.

Summary

Risk: High. Human attention should focus on:

1. vLLM version scope. The implementation pins HYBRID_EVIDENCE_VERSION = "0.33.0", adds vLLM 0.33.0 adapters, and validates exact version 0.33.0. The supplied objective says vLLM 0.31.0. Resolve this mismatch before merge.
2. Hybrid evidence validation. Import validates layer views, physical storage, cache geometry, prefix-caching settings, scheduler block sizes, and startup concurrency. The concurrency check intentionally skips layouts with a windowed group. kv_cache_size_tokens remains recorded but unused.
3. State-cache accounting and schema compatibility. State groups now carry checkpoint metadata and fixed per-request charges. fixed_request_bytes() returns u64::MAX on overflow. Python and Rust models enforce matching validation and preserve older serialized profiles.

Changed behavior and contracts

• Added vLLM 0.33.0 hybrid observation and import support.
• Added recurrent/Mamba cache specs as state groups.
• Added prefill_checkpoint_blocks and prefill_checkpoint_alignment to FPM cache-group models.
• Added phase-aware prefix-caching evidence, geometry comparison, and provenance.
• Added scheduler startup-capacity validation using Mamba checkpoint and speculative-block counts.
• Rejected unsupported specs, HiSparse placement, mamba_cache_mode="all", speculative runs, and inconsistent physical layouts.
• Preserved legacy vLLM 0.27.0 and 0.28.0 paths.
• Added audited adapters, manifests, documentation, tests, and a GLM-5.3-Flash probe fixture.
• The merge-base diff contains 46 changed files, 25,053 additions, and 268 deletions. Most additions are probe evidence and test fixtures.

Evidence supplied

• The inspected diff confirms the new observer, importer validation, Rust accounting, public profile fields, and compatibility tests.
• Python unit/parity tests, Rust tests, formatting, documentation checks, Fast CI, and Full CI are reported.
• Fast CI and Full CI are reported as passing at 46d9f8329.
• Environment-related failures are reported as matching the base branch.
• A live GLM-5.3-Flash probe and import are reported.
• Review finding counts: not available.
• Bot feedback is not approval. The bot reported CI status but did not run the tests.

Technical quality

The change has mirrored Python and Rust validation, broad malformed-layout coverage, legacy-profile compatibility tests, source-hash provenance, and explicit rejection paths. The code inspection confirms the documented sliding-window exception and unused kv_cache_size_tokens behavior.

Merge readiness

Conditional. Resolve the 0.31.0 versus 0.33.0 scope mismatch. Confirm the final-head CI logs and required test results. Review the startup-concurrency exception and state checkpoint accounting against the audited vLLM behavior.

This change adds bundled vLLM 0.33.0 runtime observation support, imports hybrid cache evidence into grouped state and attention cache records, validates phase-specific prefix-caching and geometry, extends state-group profile fields for prefill checkpoints, and updates grouped-KV scheduler diagnostics to include fixed per-request state bytes.

Merged resources now come from the first phase in request.collection_phases. Onboarding and formal-collection tests cover phase ordering, decode mismatches, and per-phase state-group geometry changes.
Account for fixed state bytes in grouped-KV admission crates/core/src/engine/kv_manager/grouped.rs, crates/core/src/engine/scheduler/vllm/core.rs, crates/core/src/engine/scheduler/vllm/grouped_tests.rs	GroupedKvPool adds fixed_request_bytes(). Admission warnings now include grouped-pool required bytes and capacity. Forward-capacity errors now append fixed state-block bytes when nonzero. Tests cover zero-byte attention-only pools, summed state-group bytes, admission rejection when a state block exceeds pool capacity, and error text with or without fixed-state details.

Full details: Description check

Explanation

The description follows the repository template closely. It has the Why and what changed, Review map, Evidence, Modeling or data provenance, and Tracking sections. It names the risk level, the public contract changes, compatibility concerns, exact test commands and results, the reviewed commits, live probe evidence, boundary cases, and expected-value derivations. The Feature Support Matrix field is filled as unaffected. Minor gaps: the Review map lists the Codex review as having reviewed commit fc1dec6, but the head commit has moved to 7a88f33 and the Fast/Full CI commit is 1c8fa60, so the tested commit versus head is not fully aligned. The description also runs long, and the title of the Tracking section names issues without a clear closing-keyword mapping for stage work. These are non-critical.

Full details: Modeling And Data Evidence

Explanation

Summary: The PR changes modeled data and selection logic. It adds the GLM-5.3-Flash vLLM 0.33.0 probe fixture, new import validation, the FpmCacheGroup checkpoint fields, and the Rust GroupedKvPool::fixed_request_bytes charge. The PR supplies provenance and reproducible before/after evidence for these changes, so the check passes. Evidence checked in the checkout: - The fixture folder python/aisimulate/tests/unit/collector/fixtures/glm53flash_vllm_0330_probe/ exists. It holds observations.json and an attempts/ tree with the prefill scheduler and worker records, source hashes and launch context. - test_import_accepts_the_live_glm53flash_record_of_vllm_0330 exists in test_runtime_observations.py (line 3077). It imports the live record against the observed values. - fixed_request_bytes is defined in crates/core/src/engine/kv_manager/grouped.rs (line 91). Its unit tests assert explicit values: 0 for attention-only groups and 20 for two 10-byte state blocks. The call site is in core.rs (line 3203). - prefill_checkpoint_alignment is defined in resources.rs with its validation rule (lines 72–122). Evidence in the PR description: - Before/after: the PR states that no prediction changes. The golden suite (tests/golden) was run and no golden file changed. - Comparison with main: 78 plain-model cases were run on main and on the branch. 66 are byte-identical, and the 12 differences are refusal-text only for invalid hand-edited records, which both sides refuse. - Expected-value derivation: the 487-block request peak (482 attention blocks plus 5 state blocks) and the 13,696-block pool are derived explicitly. test_plan_admits_the_imported_glm_draft_at_its_observed_capacity pins them. - Provenance: the fixture records its attempt, bundle, source-file hashes and the GB300 probe run. The PR lists path and identifier replacements in the fixture. - Anomaly checks: each new refusal has its own test. The author disabled each refusal in turn and confirmed that exactly its test failed. - Test failures: the 9 local failures also fail on main, so they do not come from this change. Limits (not a failure under this check): - Replay and sizing do not yet read the checkpoint fields. The PR says so and lists it as a follow-up. - The live runs used one GPU node. The PR states this limit. Linked-repository inspection was unavailable, so I did not rerun the test suites. The verdict rests on the artifacts present in this checkout and the reported evidence.

Full details: Compatibility Boundaries

Explanation

Summary: the PR keeps the Python and Rust public surfaces synchronized, keeps AISim standalone from Dynamo, and keeps the one-wheel and one-crate artifact contract. Disclosed contract changes have documented evidence. Evidence (checked at HEAD 1c8fa60, compared with main a4bbb52): - Python/Rust sync. FpmCacheGroup gains prefill_checkpoint_blocks and prefill_checkpoint_alignment in both python/aisim/src/aisim_core/fpm_profile.py and crates/core/src/perfmodel/fpm/resources.rs. Both sides use the same bounds (0 or 1; positive alignment with a count of 1). The validation error texts match. Field declaration order matches, so serialization order matches. Both sides omit absent fields on serialization. Python uses extra="forbid" and Rust uses deny_unknown_fields. - Disclosed break. Rust deny_unknown_fields means an older AISimulate rejects a profile that holds the new fields. The PR description discloses this under compatibility. It is a deliberate, additive change with tests in resources.rs. - Dynamo standalone. python/aisim/pyproject.toml lists no Dynamo or ai-dynamo dependency. The only "dynamo" hit is a keyword. No shipped src or collector module imports dynamo at package level. The new vllm_033.py imports dynamo.vllm.instrumented_scheduler, but it runs inside the target vLLM container as a probe bundle. vllm_027.py already uses the same pattern on main. The bundle manifest pins one Dynamo file hash, which is a runtime-side pin. - Artifact contract. The diff vs main has no changes to Cargo.toml, crates/core/Cargo.toml, the pyproject.toml dependency list, the maturin config, or crates/core/src/python.rs. The new bundle files (runtime/vllm-*.json, instrumentation/*.md, collector/fpm_forward/**/*.py) fall under existing wheel include globs. The new fixed_request_bytes method is pub(crate), so it is not a new crate-public API. - Versioning and bundles. The bundle gate (bundled_instrumentation.py) now accepts 0.27.0 and 0.33.0. The PR documents that every bundle hash changes, so campaigns must probe again. The schema name aisimulate-runtime-observation/v1 stays, and the new keys are additive. The 0.31.0 probe bundle exists only on the earlier PR head, not on main. The remaining 0.31.0 references in docs and op_backend_facts.yaml refer to stock vLLM collection and predate this PR. Caveat: the PR and the supplied summary cite python/aisimulate/..., but the checkout's diff against main is under python/aisim/.... Both directories exist. I used the python/aisim paths for the diff. This does not change the verdict. Not verified: I did not run the test suites. I relied on the code paths and the PR's reported results for runtime behavior.

Full details: Review Evidence

Explanation

The PR description meets all three parts of the Review evidence check. 1. Commands and results are named. The description lists the exact pytest invocations (package and root suites, with pass and fail counts), cargo test --locked -p aisim-core (3,266 passed), cargo fmt --check, ruff check and ruff format --check, and the check_* scripts. It also gives the GB300 probe commands with GPU time and import status. 2. Negative and boundary validation is present and matches the risk. A "Negative or boundary cases" section covers refused versions (0.31.0, 0.32.0, 0.33.1, 0.33.0.post1, 0.33, 0.34.0), invalid checkpoint count and alignment combinations, missing or zero kv_cache_max_concurrency, missing kernel_block_stride, unsupported RSWASpec, and the single-group hash-block rule. It states that each added refusal has a test and that each refusal was disabled in turn to confirm its test fails. It also reports a 24-combination Python/Rust reader comparison and a 55-edit fixture mutation check (46 refused). 3. Evidence types are distinguished. Local runs are separated from hosted CI, which the description marks as "Fast CI" and "Full CI" at 1c8fa60c1. Local failures are shown as also present on main. The live GB300 probe is described as a real hardware run with its exact image, versions and models. The plain-model parity comparison (78 cases against main) is labeled as such. Reviewer evidence (Codex, CodeRabbit, and an independent review) is attributed separately. Nested workflow check: the repository has an active top-level set under .github/workflows (fast-ci.yml, ci.yml named "Full CI", and pages.yml named "GitHub Pages"). The description cites only these. It does not cite the nested python/aisim/.github/workflows directory as hosted CI. The description also notes that the Stage Application Wheel job was skipped and does not present it as passing. I could not verify the hosted run results from this checkout. That does not affect this check, because the check only fails when inactive nested workflows are cited as CI evidence.

Full details: Cross-Layer Contract

Explanation

The startup-capacity contract is still incomplete. The prior FAIL claims remain true in the current tree. 1. kv_cache_size_tokens has no import consumer. The observer writes it at python/aisim/collector/fpm_forward/runtime/fpm_memory_observer.py:1078. The importer, runtime_observations.py, never reads it. The only other references are fixtures and tests that copy it through (test_runtime_observations.py:458, test_runtime_adapter.py:675, test_fpm_runtime_memory.py:706, :837). No Rust, src/aisimulate, or aisimulate_core consumer reads it either. The implementation doc (docs/perf-model/fpm-self-service/implementation.md, the scheduler-record paragraph) describes the field as recorded startup capacity and does not state that it goes unvalidated. The PR body lists this gap as a known limit. 2. Sliding-window layouts skip concurrency validation. In _validate_startup_concurrency (runtime_observations.py:1167-1168), a windowed group triggers return. The check for kv_cache_max_concurrency is then skipped for the whole scheduler. The docstring (lines 1146-1149) states this. I found no test that exercises a windowed layout against a concurrency mutation. 3. The mutation test covers only one of the two fields. test_startup_concurrency_counts_the_checkpoint_block_in_align_mode (test_runtime_observations.py:1626-1643) changes kv_cache_max_concurrency alone. It leaves kv_cache_size_tokens unchanged. The test therefore accepts a contradictory startup-capacity pair. The PR body discloses these gaps as known limits. Disclosure does not satisfy the check. The new field is a serialized output that no consumer reads, and the windowed path is not tested. The prior resolution asked for validation or removal of the field, tests for the windowed path, and updated docs. None of these changes appears in the current tree.

Resolution

1. Validate kv_cache_size_tokens and kv_cache_max_concurrency together for every scheduler and phase against the audited vLLM formula. Include sliding-window layouts, or remove kv_cache_size_tokens from the observer, its fixtures, and the docs. 2. Add a mutation test that changes kv_cache_size_tokens alone and expects an incomplete import. Add one for a windowed layout that changes kv_cache_max_concurrency. 3. Update docs/perf-model/fpm-self-service/implementation.md and the PR known-limits text to match the final rule. 4. Regenerate affected fixtures if the hashes or the validated fields change.

Approving, with one should-fix that I'd like resolved before anything reads mamba_cache_mode (Stage 5).

The should-fix: a Mamba group in align mode is recorded and imported with one block per request, but vLLM 0.31.0 holds up to 2 + k + c blocks there (details inline). It doesn't change predictions today. Grouped replay still requires prefix caching off, so vLLM runs mode none, where one block is correct. But the record already contradicts itself. The description's own probe has align mode with blocks_per_request 1, and vLLM's reported concurrency of 13,816 / 491 only works out with 2 blocks per KDA group.

What I checked against v0.31.0

• Downloaded files: they match the hashes in the manifest.
• Spec mapping: KpoolTailSpec and CircularBufferSpec hold one ring block each. RSWASpec is rightly unsupported, because its manager frees gap blocks.
• Allocation model:
  • KVCacheTensor placement and group overlay;
  • the single int8 backing buffer;
  • the indexer kernel block equal to storage_block_size;
  • Mamba view offsets and strides, as MambaBase.bind_kv_cache binds them.
• Other rules: the scheduler-copy rule, hash-block resolution and the Mamba mode rules.
• Older records: 0.27/0.28 records import as before.

Minor

• Stale docs sentence: implementation.md:1403 still says the GLM values are "the source audit's arithmetic until the live probe checks them". The description says the GB300 probe has now checked them.
• CLI wording: support/cli.py:943-946 tells users that other runtime versions need a campaign-local bundle. But the hybrid path is gated on the literal "0.31.0" in runtime/instrumentation/observer.py. A 0.28 campaign-local bundle would still produce legacy records, which import refuses for MambaSpec. Saying that hybrid import is 0.31.0-only would be more accurate.

This was a static review; I did not run a probe.

Automated approval from the AISimulate PR Review Monitor, enabled by Jason.

Reviewed commit: d32900bcf7e35a856ab86e5dc08873d5102b6bb7

9.3/10 · high confidence

This PR imports vLLM 0.33.0 hybrid attention and recurrent-state cache groups through the runtime probe into FPM profiles, including physical-layout and checkpoint validation. The incremental update switches CI to the renamed AISim runner pools and workspace paths and adds a runner canary.

9.3/10, APPROVE: no actionable current-head findings were confirmed. All 46 previously reviewed PR files are byte-identical; the 11 existing CI files contain only runner/HOME substitutions and a lint-label addition, and the new canary passed on all three pools. All 562 targeted contract tests passed across the initial run and corrected four-test PATH rerun. Full CI and fresh upstream reviews remain separate merge gates.

This approval records the code-review judgment. Remote CI completion and merge readiness are handled separately in the approved phase.

@jasonqinzhou I replaced your merge commit 425fa1ead with a signed copy, c4eb77f47. It has the same tree, parents, author and message. The unsigned commit kept Full CI from starting. @Harrilee Both of your threads have answers for the vLLM 0.33.0 version. Can you check them and resolve them if they are settled? The merge rule needs every thread resolved.
