In `@examples/trellismx/check_cpu_r27.sh`:
- Line 6: Update the validation before docker run in check_cpu_r27.sh to reject
any dirty B12X_SOURCE checkout, including tracked and untracked changes, while
retaining the pinned HEAD verification. Ensure the working tree used by the
tests is clean before it is mounted and executed.
In `@examples/trellismx/evidence-r27-20260908/verify_evidence.py`:
- Around line 17-18: Replace all validation assert statements in the verifier,
including the path, hash, shape, and KLD checks, with explicit conditional
checks that raise an error on failure. Ensure these checks execute under
optimized Python modes and prevent the final PASS output unless every validation
succeeds.
- Line 22: Update the validation flow around the audit status check to replace
the assert with an explicit runtime validation that fails clearly when statuses
do not match. Also validate the required per-arm audit flags, or consistently
enforce the documented aggregate-status contract if that is the established
interface, so the script cannot report PASS without checking the complete audit
result.
In `@examples/trellismx/serve-r27.sh`:
- Line 23: Update the validation condition in the launcher to require TP to
equal 4, while preserving the existing positive-integer and divisibility
validation for DCP. Reject all other TP values before constructing the native
runtime topology.
In `@examples/trellismx/serve.sh`:
- Line 7: Update the numeric validation in serve.sh around the length checks to
reject values exceeding the maximum allowed digit count before Bash evaluates
length arithmetically. Apply the same pre-validation before each numeric
comparison, preserving acceptance of valid positive decimal values and rejection
of oversized or out-of-range inputs.
In `@tests/quantization/test_trellismx_method.py`:
- Line 184: Replace the unconditional p8_native_kernel imports in
test_native_runtime_operator_namespace_matches_calls and the other
b12x-dependent test with pytest.importorskip, so both tests are skipped when the
B12X package is unavailable while retaining their existing coverage when
installed.
In `@vllm/model_executor/layers/quantization/modelopt.py`:
- Around line 181-183: Declare VLLM_TRELLISMX_CHECKPOINT with its appropriate
type and add it to the environment_variables registry in envs.py so validation
accepts it. Replace all four direct os.environ reads with
envs.VLLM_TRELLISMX_CHECKPOINT, including the RoutedExperts check, preserving
the existing truthiness behavior.

Register VLLM_TRELLISMX_CHECKPOINT in vllm/envs.py.
When fail_on_environ_validation is enabled, envs.validate_environ() can abort startup because the set variable is missing from environment_variables. Add its typed declaration and registry entry. Then use envs.VLLM_TRELLISMX_CHECKPOINT at all four sites; direct reads otherwise bypass the envs cache contract.

Applied the accepted review fixes in The dead pre-H128 stores/barrier are removed, while the post-H128 synchronization remains. The actual GPU reducer comparison was bitwise equal at M1/M4/M16/M128/M4096, passed graph replay, and passed real addressing beyond 2^31 elements. Microtimings do not establish a throughput gain. CPU validation totals 93 passed and 21 GPU-dependent skips. The disposition document in the B12X PR explains deferred phase traversal/FC1/diagnostic refactors. Those suggestions are not marked implemented. Current KLD tables remain prior-runtime reference evidence, not measurements of these new commits. The r27-based candidate passed all five MTP3 prefill contexts through 128K and all 12 MTP3 decode cells through C4/32K, with zero request errors or underfilled cells. Prefill at 128K measured 7517 client tokens/s. The MTP-off C4/8K CUDA illegal-memory-access failure reproduced on the original image with the same three-active-request scheduler state; it predates these fixes. The faulty kernel is still unidentified. Raw failures are retained, and no failed cell is reported as valid performance. |

@coderabbitai — your latest review of The companion Int64 correction passed actual high-offset GPU stores/graph replay and exact K4/K5 normal-path output/resource comparison. The pinned CPU suite passed 93 tests with 21 GPU-dependent skips; pre-commit passed. These are scoped checks, not a full source-image build or new full-model KLD qualification. We rejected the separate FC1 register-packing experiment: four-server ABBA comparison: 32K prefill averaged 7421.5 → 7368 tokens/s (-0.72%). All paired prefill differences were negative despite component equality and 2-CTA eligibility. The optimization is absent from both PRs and production remains on the prior image. This experiment does not implicate the distinct earlier reducer dead-store cleanup. Joint decision matrix and retained/deferred changes · comparison evidence. Published-image recipes and all historical/current KLD receipts remain unchanged, with their original KV-mode, image, topology and window provenance. No existing measurement is relabeled as testing the new source heads. |

Tip For best results, initiate chat on the files or code changes.
The stated validation scope is clear. The CPU and targeted GPU results do not claim a full source-image build or new full-model KLD qualification. The FC1 register-packing experiment is not part of this PR. The reported negative paired prefill result does not change the separate reducer dead-store assessment. The KLD receipts retain their original runtime, KV-mode, topology, and window provenance. They do not represent measurements of the updated source heads. ✏️ Learnings added

FP8 minus NVFP4: -0.0035110506; paired-window BCa95 [-0.0081718772, -0.0013675941]. FP8 lower in 22/32 windows. FP8 then NVFP4, one server per arm; zero prefix hits throughout. Already-opened conditional-fit data, not independent replication or untouched-final qualification. Capture derivative image is identified separately in the evidence.

The evidence retains cooling protocols, telemetry, all candidates, negative results and profiled diagnostics; these runs are not interchangeable repeated samples.

Current PR CPU validation:
B12X_SOURCE=/path/to/pinned/b12x bash examples/trellismx/check_cpu_r27.sh:31 quantization tests passed,39 distributed tests passed,21 GPU-only tests skipped,24 B12X contract tests passed. Pre-commit passed on changed example/docs files. Full-model measurements belong to the exact published image, not a fresh GPU run of this updated PR checkout. B12X preserves the previously reviewed generic dynamic path while integrating the selected native dispatch modules. AI assistance was used for integration, testing and evidence preparation; this updates the existing PR rather than opening duplicate work.Integration boundaries and attribution
The loader capability and RoutedExperts dispatch gates retain inherited ModelOpt carrier semantics. Persistent NCCL DCP query-gather and AG/RS workspaces are adapted from 000a28d; the PR preserves its base direct_cp_enabled policy. That composed path still needs its own GPU qualification before promotion. Current public-image measurements do not qualify every path of this source checkout.
The existing DCP1 source-build recipe remains separate. Prior September8 evidence and CodeRabbit dispositions are retained under examples/trellismx/evidence-r27-20260908 and the companion B12X docs. Historical .034x cache labeling is disputed between the owner account and archived receipts; it is not used as the matched baseline here. New September9 rows are separately audited and explicitly labeled.
Not tested on this composed PR head: native build/SM120 compilation, full-model GPU KLD, graph replay/determinism, attention/collective compatibility, MTP acceptance, speed, 1M-context quality and full-capacity stress. Previous reducer and high-offset component tests remain component evidence, not full-model qualification.
Distinct from EXL3 PR562, QSRT PR566 and W4A16 PR563: this is the native P8 overlay adapter and required loader/DCP infrastructure. Credit Brandon M.
