Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This PR adds a network-facing inference service that is exposed on all interfaces by default and allows unauthenticated, unbounded requests to consume GPU resources while returning internal failure details.

Inline comments:
In `@benchmark/lingbot_v2/check_cuda_graph_parity.py`:
- Around line 69-74: Move the mask-filtered max_vision_tokens calculation out of
the duplicated blocks into a shared helper in profile_lingbot_v2.py near
load_inputs, and have that helper validate active_patch_counts before calling
.max() so an empty input.image_masks selection raises a clear error instead of
crashing. Update the computation in check_cuda_graph_parity.py to use the
helper, and replace the duplicated block in check_patch_embed_gemm_parity.py
with the same helper call so both parity scripts share the guarded logic.
In `@benchmark/lingbot_v2/compare_moe_thor.py`:
- Around line 422-434: Update the stream construction in main to obtain top_k
and routed_scaling_factor from the loaded checkpoint configuration instead of
hard-coded literals. Require both configuration values to be present and fail
clearly when either is absent, then pass them through to benchmark_stream so
route_tokens, histograms, and parity use the checkpoint’s actual MoE settings.
In `@benchmark/lingbot_v2/compare_thor_latency.py`:
- Around line 139-140: Update the attention_backend lookup in implementation_row
so a missing metadata value defaults to None or "unknown" instead of "PHYAI",
ensuring official reports are not labeled as PHYAI when the field is omitted.
- Around line 52-60: Update patch_embed_operator so a missing
vision_patch_embed_backend field remains distinguishable as unknown rather than
defaulting to "conv3d"; preserve canonicalization for explicitly reported GEMM
and Conv3D labels, and ensure the mismatch check can flag missing metadata
instead of treating both reports as matching.
- Around line 204-213: Update the comparison-contract rendering near the
Markdown output to derive B, view count, patches per view, chunk size, Euler
steps, CUDA Graph, and torch.compile status from validated official_meta and
official_meta["contract"] rather than hard-coded claims. Ensure validate_pair
enforces these expected contract values, or otherwise render the report’s
validated values so the text cannot describe a different run.
In `@benchmark/lingbot_v2/hardware_probe.py`:
- Around line 63-90: Validate that the copy-size input produces at least one
element before allocating tensors or calculating bandwidth in
measure_memory_bandwidth_tb_s, rejecting non-positive sizes with a clear error.
Also update the elapsed-time handling in both benchmark measurement paths,
including measure_memory_bandwidth_tb_s, to reject zero or negative durations
before division, preserving normal calculations only for positive durations.
In `@benchmark/lingbot_v2/plot_lingbot_v2.py`:
- Around line 314-328: Normalize profile_diagnostics to an empty dictionary when
the key is present with a null value before using it in the CSV row generation.
Update the diagnostics initialization near the profile diagnostics handling so
the existing diagnostics.get("overhead_ratio") call remains safe, while
preserving valid diagnostic dictionaries unchanged.
- Around line 116-120: Update detail_profile_is_valid in plot_lingbot_v2.py so
it only returns true when the profile has the detail profiling payload needed by
the detail plots, not just when component_profile_is_valid passes. In the
fallback path where detail_profile_diagnostics is absent, also require
detail_gpu_ms to exist before treating the profile as valid. Keep the existing
diagnostics["valid"] check for profiles that do have detail_profile_diagnostics,
and align the validation with plot_detail_latency and plot_detail_mfu
expectations.
In `@benchmark/lingbot_v2/profile_lingbot_v2.py`:
- Around line 893-909: Guard the detailed diagnostics warning and related detail
perturbation reporting with a flag indicating that the detail pass ran, such as
detail_profile_available derived from args.use_cuda_graph. Update the output
near detail_profile_valid so skipped detail passes do not report invalid
perturbation, while preserving existing validity warnings when detailed
profiling is available.
In `@benchmark/lingbot_v2/run.sh`:
- Around line 178-194: Update the CUDA graph argument construction around
USE_CUDA_GRAPH and CUDA_GRAPH_ARGS so the disabled case explicitly passes the
profile script’s no-CUDA-graph flag, while preserving --use-cuda-graph when
enabled. Keep the existing GRAPH_SLUG naming aligned with the effective flag
value.
In
`@phyai-utils-tools/src/phyai_utils_tools/models/lingbot_v2/processor_lingbotv2.py`:
- Around line 409-441: Update the from_pretrained construction path to preserve
the loaded normalization state: do not initialize obj.dataset_stats to None when
the loaded preprocessor/postprocessor contain normalizer or unnormalizer steps.
Carry the loaded dataset statistics onto the new instance, or use an
initialization path that retains both pipelines and their normalization
metadata, ensuring those steps continue reading the correct stats.
In `@phyai/src/phyai/models/lingbot_v2/model_runner_lingbotv2.py`:
- Around line 730-743: Update _euler_loop to initialize x_t as an independent
clone of noise before the integration loop, so the in-place x_t += self._dt *
velocity updates only runner-owned storage. Preserve the existing Euler
integration and return behavior, and do not rely on callers such as
LingBotV2WS1Scheduler.step to clone the input.
In `@phyai/src/phyai/models/lingbot_v2/modeling_lingbotv2.py`:
- Around line 1699-1702: Update the position advance in the surrounding
vision-position handling to include the temporal grid extent, using int(grid[0])
as an additional candidate in the max calculation alongside the merged spatial
dimensions. Preserve the existing spatial calculations and increment behavior.
- Around line 1579-1618: Update LingBotV2DualQuery initialization and forward to
honor LingBotV2DualQueryConfig: create only the seed tables enabled by
num_query_seed_tables/use_future_depth/use_future_video, instantiate
current_shared_task_proj only when use_current_shared_task_proj is true, and
avoid producing a future query tensor when future_query_token_count is zero. If
unsupported combinations remain, validate and reject them explicitly in the
constructor instead of registering mismatched checkpoint keys.
- Around line 122-161: Replace all mojibake sequences such as “鈥?” in the
docstrings and comments with valid English punctuation, using an ASCII hyphen or
em dash consistently. Update the affected documentation near the frame-boundary
description and the corresponding comments around the referenced locations,
including the section near the model’s later code, without changing executable
behavior.
- Around line 724-727: Remove the torch.set_float32_matmul_precision("high")
call and its explanatory comment from Qwen3VLVisionModel.__init__, then apply
the setting once during engine initialization in main_lingbotv2.py or the
LingBot V2 runner setup. Keep the comment with the process-level configuration
at that entry point.
In `@phyai/src/phyai/models/lingbot_v2/scheduler_ws1_lingbotv2.py`:
- Around line 509-518: In the model class __init__, add an early validation that
cfg.suffix_len equals cfg.chunk_size + 1, raising a clear configuration error
when the relation is violated. Keep _plan_expert’s state-token and action-token
layout unchanged, and place the guard before runtime scheduling or attention
metadata is used.

Bind the result directory to the resolved task queue.
The manifest does not contain tasks. For example, after a completed two-task run, --resume --tasks lift_pot accepts the existing manifest and retains the other task log. summarize_success.py collects all eval_logs/*.log files, so the report includes a task outside the requested queue.
Add the ordered resolved task list to protocol_content. Reject the result directory when the requested queue differs.

Record the full RoboTwin and XPolicyLab revision before resuming.
Line 157 hashes only eval_policy_xpolicylab.py. If the simulator, prompts, assets, or XPolicyLab checkout changes while that file and the task config remain unchanged, lines 160-175 accept prior logs during --resume. The final report can then compare results from different simulator contracts.

Validate the RoboTwin statistics schema before concatenation.
phyai_policy_server.py passes these statistics to LingBotV2Processor with action_dim=14. _canonical_feature_stats currently skips scalar statistics and lets malformed widths pass through. With quantile normalization, a skipped q01 or q99 causes NormalizerStep to raise KeyError; an incorrect feature split can also apply bounds to the wrong joints. Validate required features, statistic names, arm/effector widths (12, 2), and the final width 14.

Keep model and benchmark-level tests out of the repository test tree.
test_lingbot_v2_processor.py directly validates LingBotV2Processor, while test_protocol_defaults.py validates runner and documentation protocol defaults. Move both tests under .cache, or replace them with layer-level component tests; repository tests should retain only layer-level coverage according to the coding guidelines.
