Migrate the BART family runtime, build declarations, manifests, and tests from legacy text_generation task mode to semantic Task SDK contract conditional_text_generation v1.0.
Key aspects addressed:
Implemented trtmc::internal::IConditionalTextGeneration in BartPipeline, retaining ITextGeneration for backward compatibility.
Implemented semantic run(ConditionalTextGenerationRequest, ConfigView) accepting either raw UTF-8 text or pre-tokenized token IDs (Span<const int32_t>).
Enforced strict input validation: rejects empty text strings, empty token spans, out-of-vocab token IDs (< 0 or >= vocab_size), and sequences exceeding max_source_length with std::invalid_argument.
Bound max_new_tokens configuration field (default 128); rejects invalid/negative/overflow values with trtmc::internal::ConfigError.
Added family-owned CPU contract tests in families/bart/tests/cpp/test_task_contract.cpp covering task bindings, text & token ID inputs, configuration handling, early EOS stopping, constructor dependency checks, legacy fallback, and result lifetime persistence.
Added public C and C++ SDK consumers in families/bart/tests/sdk_consumer.c and families/bart/tests/sdk_consumer.cpp asserting exact task output structure ({"task":"conditional_text_generation","text":...,"tokens":[...]}), validating model release before reading result view, setting struct_size = sizeof(options), and verifying exactly 1 config field.
Registered test_bart_task_contract labeled cpu in families/bart/runtime/CMakeLists.txt and wired test_bart_sdk_c and test_bart_sdk_cpp as dependencies of the contract test target per PR fix(ci): build family SDK consumers in every E2E lane #1965 contract.
Formatted all native sources to pass clang-format --dry-run --Werror (pinned v22.1.8).
Exit Criteria
BartPipeline implements internal::IModel, internal::IConditionalTextGeneration, and ITextGeneration.
ClosesNVIDIA#1433. Part of NVIDIA#1430.
Primary semantic Task: conditional_text_generation
BART accepts a source text or sequence of token IDs and produces generated text
and token IDs. The conditional_text_generation contract preserves all existing
capabilities while maintaining backwards-compatibility with text_generation.
Changes:
- runtime/pipeline.h, runtime/pipeline.cpp: BartPipeline implements
internal::IModel, internal::IConditionalTextGeneration, and ITextGeneration.
task() returns IConditionalTextGeneration::kTask.
task_bindings() declares max_new_tokens ConfigField.
run() implements conditional text generation with full input and config validation.
- runtime/plugin.cpp: updates factory to instantiate BartPipeline with task handling.
- runtime/CMakeLists.txt: wires test_bart_task_contract (labeled cpu) and adds
test_bart_sdk_c and test_bart_sdk_cpp dependencies.
- support.py: declares tasks=(conditional_text_generation, text_generation)
and default_task=conditional_text_generation.
- model.py: validates request.task and writes task metadata.
- tests/manifests/*.json: updates task to conditional_text_generation.
- tests/test_e2e.py: updates TASKS set and adds _assert_sdk_consumers.
- tests/cpp/test_task_contract.cpp: adds CPU contract tests for task bindings,
invalid inputs, configuration, early EOS stopping, and result lifetime.
- tests/sdk_consumer.c, tests/sdk_consumer.cpp: public C and C++ SDK consumers.
- tests/test_model.py, tests/test_support.py: builder and support discovery unit tests.

BART now defaults to conditional_text_generation while retaining text_generation compatibility. BartPipeline implements both interfaces, accepts text and token-ID inputs, validates requests and generation limits, and returns owned results.
The change updates BART support metadata, model validation, bundle metadata, and manifests. It adds CPU task-contract tests and C/C++ SDK consumers. The E2E test validates semantic SDK output against native output for single-device cases.
The PR reports 92 passing pytest tests, plus formatting, Ruff, legal-header, and model-validation checks. Real-checkpoint E2E results, remaining CLI/example/benchmark checks, current-head CI status, and review-finding counts are not available.
Architecture impact
Outcome: HUMAN REVIEW REQUIRED. The available evidence does not resolve the real-checkpoint validation and remaining-path requirements from linked issue #1433.
Family-owned files: All 14 changed files are under families/bart/. They cover runtime implementation, metadata, manifests, tests, SDK consumers, and build configuration.
Shared surfaces: No files outside families/bart/ changed. BartPipeline uses existing core task and runtime contracts.
Dependency direction: The BART runtime and CPU contract test link trtmc_core. The C and C++ SDK consumers link trtmc_c. No new shared-to-BART dependency is present in the changed-file inventory.
Affected consumers: BART bundles and applications using the semantic Task SDK or legacy text_generation API. The new C and C++ consumers exercise the semantic SDK path.
Open blast-radius questions: Existing bundle compatibility, real-checkpoint parity, remaining CLI/example/benchmark paths, and current-head CI status are unresolved. Whether existing bundles require rebuilding is also not documented.
BART now supports conditional text generation through the semantic Task SDK. The runtime adds an encoder-decoder pipeline with text and token-ID inputs, configurable token limits, and EOS stopping. Build metadata, manifests, CPU contract tests, C and C++ SDK consumers, and end-to-end checks are updated.
BART accepts conditional_text_generation and text_generation, with conditional text generation as the default. The pipeline declares the semantic task interface and max_new_tokens configuration.
BartPipeline prepares inputs, runs the encoder, binds cross-attention buffers, and generates tokens until EOS or the configured limit. The plugin constructs the pipeline.
CPU pipeline contract tests families/bart/tests/cpp/test_task_contract.cpp, families/bart/runtime/CMakeLists.txt
CPU-backed tests cover task bindings, input and configuration validation, generation behavior, dependency checks, and legacy generation. CMake registers the test.
SDK consumers and end-to-end checks families/bart/tests/sdk_consumer.c, families/bart/tests/sdk_consumer.cpp, families/bart/tests/test_e2e.py, families/bart/runtime/CMakeLists.txt
C and C++ consumers run conditional text generation. Single-GPU end-to-end checks compare consumer results with each other and with nonempty native output.

Merge Risk: Moderate · up to d6130
Existing BART CLI invocations that pass --temperature or --top-k are rejected once the default task changes, and the BART end-to-end test is likely to fail. The SDK parity check can also fail when a case hits its token limit. Resolve both before merging.
Security architecture risk: Moderate · up to d6130
The new token-input interface has a length-check weakness that can permit native memory corruption for exceptionally large inputs. Exploitation requires substantial memory and access to the interface; broader network exposure has not been established.
Retained concerns
Medium · security · inferred: The new public token-input path does not preserve its source-capacity invariant for large counts. It casts ids.size() to int32_t before checking max_source_length, but copies ids.size() elements into the fixed-capacity padded buffer. Counts that narrow to a negative or small value can bypass rejection and cause a heap overwrite if the large input allocations succeed. The SDK adapter checks host address-range overflow, not the model source limit. This introduces a native-memory failure path absent from the legacy bounded-copy operation.
Security review details
Security Blast Radius
inferred — The identified attack surface is a caller-controlled token array reaching native memory operations in the hosting process. Triggering the length bypass requires an exceptionally large valid array and successful multi-gigabyte allocations. A resulting overwrite can affect the hosting process; remote reachability, tenant sharing and cross-service exposure were not established.
Security Findings and Attack Paths
inferred — A post-normalization sequence of 2^31 valid tokens occupies 8 GiB. With ordinary 32-bit narrowing, its length becomes negative at the source-limit comparison, so rejection is bypassed and copy_n attempts to write the full sequence into the much smaller padded buffer. Vocabulary validation and the model mutex do not enforce capacity. Allocation failure can prevent this path, and no executable exploit was run. The base copied a bounded count and offered no direct token-ID interface.
Trust Boundaries and Controls
observed — Public semantic calls hold a per-model mutex across task execution. Configuration validation and semantic input preparation precede mutable encoder execution; token spans reject empty input and out-of-vocabulary IDs. These controls constrain ordinary requests but do not repair the full-width length-check gap.
Resilience and Maintainability Implications
observed — Output text and tokens are owned by result storage rather than borrowed from the pipeline. The C consumer releases the model before reading the result view, and the CPU contract test retains output after pipeline destruction.
observed — Decoder reset and cross-attention copying retain the legacy execution pattern, including unchecked CUDA copy return values. These are inherited recovery limitations, not established PR regressions. The inspected transition relies on reset at the next execution rather than explicit transactional rollback.
Hardening Proposals
proposed — Enforce the source-capacity invariant using the full-width count before scanning or copying token input, account for BOS/EOS expansion, and narrow only after proving the count fits. Bound the padded-buffer copy by that validated count.

Resolution

Full details: Benchmark Validation Integrity
Explanation
The new SDK comparison uses different generation limits. bart-base.json sets 20 tokens, and _native passes that limit to the CLI. Both SDK consumers omit configuration, so BartPipeline::run uses 128 tokens. _assert_sdk_consumers compares their text with the native result despite the different requests. Early EOS can hide the mismatch. The native path also passes --temperature and --top-k, which the semantic CLI rejects because BART declares only max_new_tokens. This currently prevents the E2E test from reaching the comparison.
Resolution
Remove the unsupported CLI options. Pass the manifest token limit to both SDK consumers and compare their text and token IDs with the corresponding native result. Alternatively, remove the cross-path equality assertion and document the SDK default in an independent contract check.
Full details: Linked Issues check
Explanation
For [#1433], the diff implements the BART semantic migration. It adds IConditionalTextGeneration, preserves ITextGeneration, validates text and token inputs, binds max_new_tokens, returns owned results, updates support/model metadata and manifests, and adds CPU contract and C/C++ SDK tests. families/bart/tests/test_e2e.py contains a selected-checkpoint oracle and threshold path for facebook/bart-base. The reported validation does not include a selected real-checkpoint E2E result or results for the remaining declared capabilities and public CLI, example, and benchmark paths. The implementation of those checks exists only in part, so full compliance with the issue cannot be established.
Resolution
Provide the selected real-checkpoint E2E command and result, including oracle and threshold evidence, and provide results for the remaining declared capabilities and public CLI, example, and benchmark paths. The available evidence does not establish whether these checks passed.

Pass the case token limit to the SDK consumers, or the text equality check can fail.
_native passes case["max_new_tokens"] to the CLI (test_e2e.py:268). The SDK consumers accept only BUNDLE RUNTIME_ROOT TEXT (sdk_consumer.c:49, sdk_consumer.cpp:30) and do not set max_new_tokens. The pipeline then uses its default of 128 (pipeline.h:28, pipeline.cpp:93). Both shipped BART manifests set the limit to 20 (bart-base.json:15, bart-base-tp4.json:12).
If a case does not reach EOS within 20 tokens, the consumer output can run longer than the native output. The check at line 337 (assert actual["text"] == expected_text) then fails on the length difference. The native text is passed in from line 361.
Set the consumers' generation limit to the case value, for example through an optional argument. Otherwise, confirm that every case reaches EOS before its max_new_tokens limit.

Add AIPerf defaults for the renamed BART task
When AIPerf resolves the ready bart-base profile, this changes its task to conditional_text_generation, but apps/aiperf_qual/config/tasks.yaml defines only text_generation; resolve_model() raises ConfigError when the task key is missing (apps/aiperf_qual/trtmc_aiperf_qual/models.py:202-203). Because the bart-base profile still opts into the bart_denoise qualification suite, it becomes unresolvable; add a conditional-task policy or alias before changing this manifest.
