fix: accept vLLM patch releases with unchanged audited files in FPM observation - #788
PR #765 lets FPM self-service collect on vLLM 0.32.0 and 0.33.0, but only on those exact versions. A vLLM patch release (0.x.y), for example 0.33.1, stops Example B again: memory stays pending, and the execution gate stays incomplete. The vLLM code that the observers read can be unchanged, and the run still stops. Dynamo 1.7.x can move to a vLLM patch release after aisimulate 0.14.0 ships.
This PR accepts a final patch release of the 0.32 or 0.33 line on one condition. Every vLLM source file that the observers read must be byte-identical to the audited release. The PR changes five things:
The observer has one rule, audited_release. The observer accepts an audited version as before, with no new check. A final release has three or more numeric parts. If its line holds an audited release with a source manifest, the observer makes two checks. The imported vllm package must report the same version as the package metadata. Every file in the manifest must be installed exactly once with the same SHA-256. If both checks pass, the observer accepts the version. The manifests cover 36 files for 0.32.0 and 38 for 0.33.0. They are a constant in fpm_memory_observer.py, so no new file ships to the container. The observer finds each file through the imported vllm package and hashes each file once per process. Pre-release, development and local builds (for example 0.33.1rc0 and 0.33.1+cu130) are refused. The 0.27 and 0.28 lines have no manifest, so they keep exact version checks.
A new script, collector/fpm_forward/vllm_source_manifest.py, recomputes the manifest hashes from the pinned vLLM tags. With --check, it compares them with the constant.
Every memory and execution record of an accepted patch release carries audited_backend_version, resolved or unresolved. If a file changed, the record is unresolved, and its error names the file, for example installed vLLM 0.33.1 does not match audited vLLM 0.33.0: vllm/config/cache.py differs. If the imported package reports another version, the record is unresolved, and its error names both versions, for example vLLM package metadata reports 0.33.1, but the imported vllm package reports 0.33.0.
The planner, the runner, onboard finalize, the validate-collection execution gate, the onboarding support plan and the guided review apply the same rule. No image exists at planning time, so they use the version part of the rule, and the check in the container decides. Finalize and the execution gate require the audited release in every record of a patch release. The collection plan records audited_vllm_version, and the finalize provenance records audited_backend_version.
implementation.md describes the rule.
The consumers are FPM self-service users whose Dynamo image ships a vLLM patch release.
Public or serialized contract changed: yes, for accepted patch releases only.
Their records, collection plans and finalize provenance carry the new fields above. Their support plans name the plan's own version and the audited release in the memory prerequisite.
For vLLM 0.27.0, 0.28.0, 0.32.0 and 0.33.0, nothing changes: plans, plan hashes, records, provenance, texts and messages stay the same. The same holds for every version refused today, for example 0.27.1 and 0.33.1rc0. Only an accepted patch release gets a new field. Tests pin the existing policies and texts.
Feature Support Matrix: unaffected.
Compatibility or rollback concern:
support/plan.py keeps its own copy of the rule, because onboarding must not import the observer. A mirror test keeps the two copies equal.
If the package check or the file check fails for a patch release, the observer writes an unresolved record. Timings are still collected. onboard finalize then refuses with the observer's error, and the profile stays pending.
A plan saved before this PR for a 0.32.x or 0.33.x patch version fails closed. check_plan reports the support plan as modified, a resumed collection stops at the plan hash check, and load_repeatability_source refuses the collection plan. The plan must be made again, as fix: support vLLM 0.32.0 and 0.33.0 in FPM self-service collection #765 required for 0.32.0 and 0.33.0. vLLM has no final patch release of these lines yet, so no such plan comes from a real image. Tests pin the three refusals.
A new vLLM minor release (0.x), for example 0.34.0, still needs a source audit and a manifest. From August 2025 to August 2026, 5 of the 15 vLLM patch releases changed none of the 38 manifest files.
Tests: the full unit suite on 741a181 (macOS) has the same failing set as the base 912e917: 122 test IDs, none in a file that this PR touches. The 66 new tests pass, and no test is missing. Ruff check and ruff format pass. The head 4341093 adds documentation only, and the three test files of this PR pass on it (431 tests).
Manifests: python -m collector.fpm_forward.vllm_source_manifest --vllm-source <vllm checkout> --check passes on c1f5284 against v0.32.0 (5df63a72) and v0.33.0 (4ba787ec). Before the change, the vLLM package in the Dynamo 1.7.0-rc.1 and rc.2 images was compared with the tags. Every Python file of the tags is byte-identical in the images (2,641 files for v0.32.0 and 2,990 for v0.33.0).
Image run: on 2026-11-09, the observer of b6a44b8 ran with the image Python in two CPU jobs on nscale. In Dynamo 1.7.0-rc.2 (vLLM 0.33.0), audited_release maps 0.33.1 to 0.33.0 for memory and execution and refuses 0.33.1rc0. The file check finds all 38 manifest files unchanged. In rc.1 (vLLM 0.32.0), 0.32.1 maps to 0.32.0, and all 36 manifest files are unchanged. The run called audited_release and the file check directly, and 741a181 changes neither function. In both images, vllm/_version.py and the package metadata are byte-identical to the PyPI wheels of vLLM 0.32.0 and 0.33.0. So the imported package reports the installed version and passes the new package check.
Fast CI: passed on 4341093. Across all workflows on that commit, 65 checks passed and 8 were skipped. The extra skipped check is the CodeRabbit status, which is not a required check.
Full CI: the automatic copy-pr-bot run on pull-request/788 passed on 4341093. The advisory simulation performance comparison ran and passed. The forward-prediction comparison did not run, because its selector found no changed file that affects forward prediction.
CodeRabbit reviewed commit: 741a181, and it checked 4341093 in the thread. Its two Trivial comments on c1f5284 are resolved. 55a7f48 adds the requested sentence, and CodeRabbit withdrew the other comment because test_support_plan.py already makes the assertion. Its Major comment on 55a7f48 said that the file check reads the imported vllm package while the records take the version from the package metadata. 741a181 fixes it. On 741a181 it posted two Minor comments on the implementation.md paragraph. 4341093 addresses both, CodeRabbit agreed, and the thread is resolved. Its Cross-Layer Contract and Compatibility Boundaries checks flagged the refusal of saved patch-release plans, which the review map and the guide now describe.
Codex reviewed commit: 741a181, with a local codex exec review against main 912e917 (codex-cli 0.167.0, model gpt-6.1-sol). Its banner reported sandbox: danger-full-access, although the run set -s read-only. It found no actionable regression. It ran 748 tests, and they passed. It changed no file in the checkout. An earlier version of this line called the b6a44b8 review read-only. That run used the same flags as a later run whose banner reported full access, so that claim was most likely wrong.
Negative or boundary cases:
Refused versions: 0.27.1, 0.31.2, 0.34.0, 0.33.1rc0, 0.33.1.dev3+gabc1234, 0.33.1+cu130, 0.33.0.post1, v0.33.1, 0.33.1, 0.33, None, a version with non-ASCII digits, and 0.28.1 for execution.
File check: a changed file, a missing file, and a file under two package roots are refused, and the error names the file. The check runs once per process.
Package check: for a patch release, an imported vllm package that reports another version (0.33.0 or dev) or no version is refused. The refusal comes before the file check, and the error names both versions. Exact audited versions skip this check.
Newest audited release: 0.33.10 is chosen over 0.33.9.
Evidence: finalize and the execution gate refuse a patch-release collection in three cases. A record has no audited release, a record has a wrong one, or only the last record misses it.
Expected-value derivation: the finalize test for 0.33.1 expects 88 * 128 bytes, the value that the existing 0.32.0 and 0.33.0 layer-strided tests assert for the same fixture. A patch release must give the same result as its audited release.
Before/after output: on the base, a 0.33.1 worker record is unresolved with memory observation currently supports vLLM 0.27.0, 0.32.0, 0.33.0; found 0.33.1. With this PR, the record resolves and carries audited_backend_version: 0.33.0.
Modeling or data provenance
The manifests come from the pinned vLLM tags v0.32.0 (5df63a7203cdb9328d824a27b682e77c7b9928be) and v0.33.0 (4ba787ec9959e566d3b587a796dff07673324da5). The file list comes from the PR #765 source audit of the observers. No published data changes.

Risk: Medium. Three areas need the most human attention:
Source-manifest coverage: vLLM 0.32 and 0.33 patch releases are accepted only when every manifest-listed file matches the audited release. Review manifest completeness and how the check handles installed layouts with missing or duplicate files.
Evidence enforcement: Memory finalization and execution validation require audited_backend_version when the installed patch version differs from the audited release. Confirm that each evidence path rejects missing or incorrect audit records.
Policy consistency: The collector and onboarding plan implement separate release-selection logic. Tests compare them, but future changes must keep both policies aligned.
Changed behavior and contracts
The observers accept final patch releases in vLLM 0.32 and 0.33 when all audited source files match vLLM 0.32.0 or 0.33.0. Pre-release, development, local, and unsupported versions remain refused. Accepted patch-release evidence records audited_backend_version; failed source checks leave observations unresolved.
Planning, collection eligibility, memory finalization, execution validation, and onboarding apply the release mapping. Plans and onboarding guidance identify the audited release. The new manifest tool generates and checks hashes against pinned vLLM tags. The implementation documentation describes the acceptance rule.
The merge-base diff contains 12 changed files, with 950 lines added and 27 removed. New tests cover release selection, manifests, evidence validation, and onboarding-plan consistency.
Evidence and merge readiness
The objectives report passing tests, lint, manifest checks, and CI. They also report that the full unit suite had the same 122 failing test IDs as the base. These results are not independently established as completed checks on the current head. Current-head check results are not available.
Review-finding severity counts are not available. The reported bot review is not approval.
Technical quality evidence includes targeted tests and explicit evidence checks. Merge readiness is not available without verified current-head check results and supplied review findings.
Final vLLM patch releases on audited 0.32 and 0.33 minor lines can use memory and execution observation when the observer-read files match the audited release. Plans, evidence, and finalization provenance identify the audited release and retain the installed patch version.

Reviewed commit cbd7465 against stacked base 1860f12. No actionable findings. Traced version admission through planning, runtime observation, execution evidence, and memory finalization. Patch releases require the audited files from the imported vLLM package to match, and every worker/scheduler record must carry the expected audited version. Existing exact-version behavior and explicit rejection of incompatible saved plans remain intact.
Validation: independently fetched all 74 manifested upstream files from the pinned commits and recomputed matching SHA-256 digests (74/74). All 709 selected CPU tests passed, including the 14 multiprocessing cases rerun with a normal module launcher after resolving a local harness path issue. Ruff and diff checks passed; current-head Fast CI and Full CI are green. Local tests used the unchanged native runtime from the base #765 CI wheel. No GPU runtime or future patch-release qualification is claimed.

Bind the distribution version to the imported vLLM tree.
If PYTHONPATH selects a 0.33.0 source tree while distribution metadata reports 0.33.1, the source check passes against 0.33.0. Memory and execution evidence can then record 0.33.1 for code from 0.33.0. The downstream identity checks compare the same metadata-derived version and do not detect the mismatch. Reject this ambiguous identity before accepting patch-release evidence.

- Line 1717: Update the pending-memory collection compatibility guidance to
state that plans created before 0.32.x/0.33.x patch-release support cannot be
reconstructed or resumed by the new collector. Tell users to preserve the old
artifacts and create a new reviewed campaign; do not rely on the general
onboarding-plan regeneration guidance to cover this checkpoint limitation.
- Line 1717: Narrow the package-version guarantee in the observer documentation
to accepted patch releases: `_check_release` permits an exact audited release
such as 0.33.0 when the imported package reports `dev`. Keep the exact installed
version in provenance, and do not claim that observers refuse version mismatches
for exact audited releases.

The frozen FPM loader requires both sidecar and row backend_version to match the database version directory. Retaining the installed patch version is therefore important; the audited base is not interchangeable as the database identity. [::ai-dynamo/aiconfigurator::aic-core/rust/aiconfigurator-core/src/perf_database/fpm_forward.rs:391-405] [::ai-dynamo/aiconfigurator::aic-core/rust/aiconfigurator-core/src/perf_database/fpm_forward.rs:596-601]
If audit provenance is ever added to parquet rows, mixed old/new rows need normalization: the frozen writer already does this for another additive column because PyArrow can otherwise omit it. [::ai-dynamo/aiconfigurator::collector/fpm_forward/database.py:534-545]

Why and what changed
PR #765 lets FPM self-service collect on vLLM 0.32.0 and 0.33.0, but only on those exact versions. A vLLM patch release (0.x.y), for example 0.33.1, stops Example B again: memory stays pending, and the execution gate stays incomplete. The vLLM code that the observers read can be unchanged, and the run still stops. Dynamo 1.7.x can move to a vLLM patch release after aisimulate 0.14.0 ships.
This PR accepts a final patch release of the 0.32 or 0.33 line on one condition. Every vLLM source file that the observers read must be byte-identical to the audited release. The PR changes five things:
audited_release. The observer accepts an audited version as before, with no new check. A final release has three or more numeric parts. If its line holds an audited release with a source manifest, the observer makes two checks. The importedvllmpackage must report the same version as the package metadata. Every file in the manifest must be installed exactly once with the same SHA-256. If both checks pass, the observer accepts the version. The manifests cover 36 files for 0.32.0 and 38 for 0.33.0. They are a constant infpm_memory_observer.py, so no new file ships to the container. The observer finds each file through the importedvllmpackage and hashes each file once per process. Pre-release, development and local builds (for example0.33.1rc0and0.33.1+cu130) are refused. The 0.27 and 0.28 lines have no manifest, so they keep exact version checks.collector/fpm_forward/vllm_source_manifest.py, recomputes the manifest hashes from the pinned vLLM tags. With--check, it compares them with the constant.audited_backend_version, resolved or unresolved. If a file changed, the record is unresolved, and its error names the file, for exampleinstalled vLLM 0.33.1 does not match audited vLLM 0.33.0: vllm/config/cache.py differs. If the imported package reports another version, the record is unresolved, and its error names both versions, for examplevLLM package metadata reports 0.33.1, but the imported vllm package reports 0.33.0.onboard finalize, thevalidate-collectionexecution gate, the onboarding support plan and the guided review apply the same rule. No image exists at planning time, so they use the version part of the rule, and the check in the container decides. Finalize and the execution gate require the audited release in every record of a patch release. The collection plan recordsaudited_vllm_version, and the finalize provenance recordsaudited_backend_version.implementation.mddescribes the rule.The consumers are FPM self-service users whose Dynamo image ships a vLLM patch release.

git range-diffshows every commit unchanged, and the whole diff has the samegit patch-id --stableas before.python -m collector.fpm_forward.vllm_source_manifest --vllm-source <vllm checkout> --checkpasses on c1f5284 against v0.32.0 (5df63a72) and v0.33.0 (4ba787ec). Before the change, the vLLM package in the Dynamo 1.7.0-rc.1 and rc.2 images was compared with the tags. Every Python file of the tags is byte-identical in the images (2,641 files for v0.32.0 and 2,990 for v0.33.0).audited_releasemaps 0.33.1 to 0.33.0 for memory and execution and refuses0.33.1rc0. The file check finds all 38 manifest files unchanged. In rc.1 (vLLM 0.32.0), 0.32.1 maps to 0.32.0, and all 36 manifest files are unchanged. The run calledaudited_releaseand the file check directly, and 741a181 changes neither function. In both images,vllm/_version.pyand the package metadata are byte-identical to the PyPI wheels of vLLM 0.32.0 and 0.33.0. So the imported package reports the installed version and passes the new package check.pull-request/788passed on 4341093. The advisory simulation performance comparison ran and passed. The forward-prediction comparison did not run, because its selector found no changed file that affects forward prediction.test_support_plan.pyalready makes the assertion. Its Major comment on 55a7f48 said that the file check reads the importedvllmpackage while the records take the version from the package metadata. 741a181 fixes it. On 741a181 it posted two Minor comments on theimplementation.mdparagraph. 4341093 addresses both, CodeRabbit agreed, and the thread is resolved. Its Cross-Layer Contract and Compatibility Boundaries checks flagged the refusal of saved patch-release plans, which the review map and the guide now describe.codex exec reviewagainst main 912e917 (codex-cli 0.167.0, model gpt-6.1-sol). Its banner reportedsandbox: danger-full-access, although the run set-s read-only. It found no actionable regression. It ran 748 tests, and they passed. It changed no file in the checkout. An earlier version of this line called the b6a44b8 review read-only. That run used the same flags as a later run whose banner reported full access, so that claim was most likely wrong.v0.33.1,0.33.1,0.33,None, a version with non-ASCII digits, and 0.28.1 for execution.vllmpackage that reports another version (0.33.0ordev) or no version is refused. The refusal comes before the file check, and the error names both versions. Exact audited versions skip this check.88 * 128bytes, the value that the existing 0.32.0 and 0.33.0 layer-strided tests assert for the same fixture. A patch release must give the same result as its audited release.memory observation currently supports vLLM 0.27.0, 0.32.0, 0.33.0; found 0.33.1. With this PR, the record resolves and carriesaudited_backend_version: 0.33.0.Modeling or data provenance
The manifests come from the pinned vLLM tags v0.32.0 (5df63a7203cdb9328d824a27b682e77c7b9928be) and v0.33.0 (4ba787ec9959e566d3b587a796dff07673324da5). The file list comes from the PR #765 source audit of the observers. No published data changes.
