Background

#1093 removed the legacy bundle provenance fields while moving to the fixed v1 header. New bundles therefore no longer identified the exact checkpoint or TRTMC source that produced them, benchmark cache entries were reused without identity checks, most remote manifests resolved mutable checkpoint revisions, and many family dependency declarations remained bare or ranged.

This is a forward fix on top of #1093. It does not restore the legacy bundle shape or revert the family-isolated architecture.

Exit Criteria

  • Every new CLI-produced bundle carries an exact checkpoint identity, exact source revision, and all build-affecting request identities that trtmc inspect can report.
  • Provenance remains core-owned without reserving a family section name or changing the fixed v1 header.
  • Benchmark-managed bundles are reused only for an exact provenance match and fail closed under --no-build; an explicit Hugging Face model directory must resolve to the manifest's exact snapshot SHA.
  • Every remote model manifest pins an exact Hugging Face commit.
  • The pinned base environment and family-owned direct dependencies use exact versions. Package metadata remains a bounded compatibility contract that admits every family-owned exact pin instead of becoming a central family lock.

Implementation

  • Append provenance as a bounded core-owned trailer after all family sections. The trailer is outside the fixed header and section payload, and new readers prevent family section ranges from overlapping it. Replace the generic application-facing section reader with a dedicated provenance API.
  • Require local CLI builds to provide --checkpoint-id and an immutable --revision. Hugging Face inputs retain exact 40-character commits; non-Hugging-Face sources use explicit resolved provider version-object IDs. Reject mutable aliases and dirty locally inferred source checkouts.
  • Require a stable graph_transform_id whenever a graph transform is used and include it in provenance.
  • Preserve generalized checkpoint identity in the benchmark catalog and validate it before cache lookup. Reject arbitrary --model-dir overrides for Hugging Face manifests unless the resolved path ends in /snapshots/<manifest SHA>.
  • Validate the complete fixed-v1 header, section descriptors, and section bounds before a provenance match can reuse a cached bundle.
  • Pin all remote manifests and family-owned direct dependencies. Keep exact Docker/base defaults while enforcing that pyproject.toml compatibility bounds accept every exact family version.
  • Preserve the prepare-structure command and family-owned default precision introduced on main while keeping provenance validation confined to bundle builds. Apply the existing exact Pillow pin to families added after the original PR base.
  • Add regression and architecture tests for trailer isolation, exact CLI identity, dirty checkout rejection, graph-transform identity, snapshot override validation, cache invalidation, and dependency compatibility.

Validation

Commands and Results

  • python -m pytest core/builder/tests/test_build_cli.py -q: passed, 13 tests.
  • python -m pytest core/builder/tests apps/benchmark/trtmc_benchmark/tests tools/tests -q -x -m 'not gpu and not trt' -p no:cacheprovider: passed, 408 tests.
  • python -m tools.community_ci source-quality --base github/main: passed, including 129 source and architecture tests plus formatting and source checks.
  • cmake -S . -B build -DCMAKE_CUDA_COMPILER=/usr/local/cuda-13.1/bin/nvcc -DCMAKE_CUDA_ARCHITECTURES=89 -DTRTMC_ENABLE_BYOK=OFF -DTRTMC_BUILD_EXAMPLES=OFF: configured successfully.
  • cmake --build build --target test_bundle_format_v1 test_cli -j2 && ./build/test_bundle_format_v1 && ./build/test_cli: passed; both C++ programs reported ALL PASSED.
  • git diff --check github/main...HEAD: passed.

Hardware, Environment, and Revisions

  • Tested repository head: 818d34c86e17eb524dc354f10e68055dd20ea052; base: 5c0bedd8549fd60eec3340a51477d83a20d91c54.
  • Local validation covered CPU/static Python tests and C++ bundle/CLI behavior on Linux/x86_64 with CUDA 13.1 used for CMake configuration. No GPU inference path was exercised.
  • The branch was rebased onto current github/main. Current GitHub and Internal CI results must be taken from this exact head; results from earlier PR heads are not evidence for this revision.

Not Run / Remaining Gaps

  • GPU model end-to-end inference, numerical parity, performance, and model qualification were not run locally.
  • Clean multi-platform installation of every family dependency set and a rebuilt Docker image were not run locally. Exact direct pins still require family-owner and target-environment qualification.
  • Direct pins do not create a repository-wide transitive lock graph; that remains intentionally outside the family-isolated dependency design.
  • Low-level Python callers may omit checkpoint identity for family-local tests, but must supply it to produce exact provenance. The CLI and benchmark paths now fail instead of emitting an unknown checkpoint revision.

Contributor Self-Review

  • I have completed a self-review of this change.

Notes For Future Readers

  • Review the provenance trailer and section-boundary validation first, then the CLI/benchmark identity checks, followed by the dependency compatibility gate and mechanical manifest/requirements pins.
  • The provenance trailer is deliberately not a named section: section names, schemas, order, and semantics remain entirely family-owned.
  • Pre-fix bundles without provenance remain valid runtime inputs but are rejected as benchmark cache hits.

Risk level

  • Low
  • Medium
  • High

Risk rationale: this changes public build inputs, bundle bytes, benchmark cache reuse, checkpoint revisions, and dependency resolution across many family-owned files. Exact-head CI and downstream family qualification are required before release.

📝 Summary

Summary

This change restores reproducible bundle identity without changing the fixed v1 header or family-isolated architecture.

  • Bundles store optional provenance in a bounded core-owned trailer.
  • Provenance records checkpoint, source, graph-transform, and build-request identity.
  • Build paths reject missing, mutable, or ambiguous revisions.
  • Benchmark reuse requires exact provenance and structural validation.
  • trtmc inspect reports provenance through InspectBundleProvenance.
  • Model manifests and dependency declarations use pinned revisions and versions.
  • Tests cover provenance, cache reuse, revision validation, CLI inspection, and dependency policies.

Architecture impact

Shared surfaces

  • BuildRequest carries checkpoint and graph-transform identity.
  • Build APIs resolve source revisions and reject dirty worktrees.
  • Bundle readers and writers validate provenance, headers, sections, and bounds.
  • The fixed v1 header and family section table remain unchanged.
  • Benchmark reuse depends on complete provenance equality.
  • The public bundle API and CLI expose provenance metadata.

Family-owned files

  • Family manifests now pin Hugging Face revisions.
  • Non-Hugging Face manifests define checkpoint identity and immutable revisions.
  • Family requirement files use pinned dependency versions.

Dependency direction

  • Open and minimum dependency constraints move toward exact pins.
  • Project and family dependency constraints must remain compatible.
  • Docker dependencies use pinned versions.

Affected consumers

  • Python build API callers must provide immutable checkpoint metadata.
  • Graph-transform callers must provide a stable graph_transform_id.
  • Local checkpoint callers must provide --checkpoint-id and an immutable revision.
  • Benchmark users with incomplete or mismatched provenance must rebuild bundles.
  • CLI users can inspect provenance with trtmc inspect.

Unresolved blast-radius questions

  • GPU inference and downstream model qualification remain unvalidated.
  • Multi-platform dependency installation remains unvalidated.
  • Docker rebuild validation remains unvalidated.
  • Compatibility with downstream direct BuildRequest construction requires confirmation.
  • Compatibility with downstream bundle readers requires confirmation.

Review status

HUMAN REVIEW REQUIRED

PASS: Python and C++ tests, source-quality checks, and git diff --check passed.

BLOCK: GPU inference, multi-platform dependency installation, Docker rebuild validation, and downstream qualification were not run.

Walkthrough

The build system now requires immutable checkpoint, graph-transform, and source revisions. It stores provenance in bundle trailers and uses that data for inspection and benchmark reuse. Model manifests and dependency declarations now use pinned revisions and versions.

In `@core/builder/tensorrt_model_connect/build_cli.py`:
- Line 118: Update the revision resolution logic in the function containing the
requested return so local directories outside Hugging Face snapshot paths never
return a non-SHA value such as "main"; return an empty unresolved revision or
reject the argument with the CLI’s established validation error, while
preserving valid snapshot SHA handling.

In `@core/builder/tensorrt_model_connect/build.py`:
- Line 140: Update the build flow around family_module.build() and
_build_provenance() to resolve and store the source provenance before the family
build begins, then pass that frozen value to writer.add_json("provenance.json",
...) after the build completes. Ensure provenance.json reflects the revision
that produced the bundle.

In `@core/builder/tests/test_build.py`:
- Around line 195-251: Make the core builder tests model-agnostic: in
core/builder/tests/test_build.py lines 195-251, update
test_build_embeds_checkpoint_and_source_provenance to use neutral family and
checkpoint values; in core/builder/tests/test_build_cli.py lines 113-203, mock
family resolution and use a neutral local checkpoint fixture. Remove literal
model or family names from both affected ranges while preserving the generic
builder contract assertions.

Inline comments:
In `@apps/benchmark/trtmc_benchmark/catalog.py`:
- Around line 177-180: Update the manifest validation near the checkpoint
identity check to require a non-empty, immutable hf_revision whenever hf_id is
set, using the existing immutable-revision validation rule before
BundleBuilder._plan() resolves the model. Reject missing or mutable revisions
while preserving the existing checkpoint_id/checkpoint_revision validation.

In `@core/builder/tensorrt_model_connect/build.py`:
- Around line 58-64: Update BuildRequest.__post_init__ to require non-empty
checkpoint_id and checkpoint_revision for all callers, including direct build()
invocations; validate checkpoint_revision against _IMMUTABLE_CHECKPOINT_REVISION
without allowing empty values, while preserving the existing ValueError behavior
and message for invalid revisions.

In `@core/builder/tensorrt_model_connect/bundle_writer.py`:
- Around line 59-60: Update the header validation in BundleReader so it
validates the complete v1 header schema and section layout, not merely that
header is a dict, before returning provenance. Reuse the existing v1 validation
logic and ensure malformed or incomplete headers are rejected consistently with
the runtime loader.

Inline comments:
In `@core/builder/tensorrt_model_connect/build.py`:
- Around line 58-64: Update checkpoint_revision validation and provenance
handling around _IMMUTABLE_CHECKPOINT_REVISION, _build_provenance, the
local-directory CLI path, and BuildRequest so stored identities are always
resolved content identifiers: accept exact Git SHAs directly, but resolve
namespaced revisions such as hf:main to their immutable SHA before passing or
persisting them. Ensure benchmark cache comparisons use the resolved SHA rather
than the original label.

In `@core/builder/tensorrt_model_connect/bundle_writer.py`:
- Around line 59-60: Update _bundle_matches_model() and the cached-bundle path
in _prepare_group() to validate headers with the same runtime-equivalent schema
checks as BundleReader, including required sections, supported fields, and
section bounds, before returning a cache hit or marking the bundle reused.
Ensure read_bundle_provenance() cannot make an incomplete or unsupported header
appear reusable.

In `@core/builder/tests/test_bundle_writer.py`:
- Line 35: Update the provenance defaulting expression in the bundle writer test
helper to use an explicit None check, preserving explicitly supplied falsey
values such as {}, [], "", 0, and False while still applying {"format": 1} when
provenance is None.

Inline comments:
In `@core/builder/tensorrt_model_connect/build.py`:
- Around line 61-63: Update the BuildRequest dataclass fields checkpoint_id and
checkpoint_revision to be required, and validate both in
BuildRequest.__post_init__. Reject empty values, accepting checkpoint revisions
only as exact 40-character Git SHAs or resolved provider version-object IDs in
the <provider>:version:<id> format; preserve the core’s model-agnostic contract.
- Around line 201-204: Update resolve_source_revision so the git-discovered
revision is used only when the discovered work tree owns the package source,
rather than accepting an enclosing unrelated repository. If ownership cannot be
verified, require the embedded package revision or TRTMC_ENGINE_BUILD_REVISION
instead, while preserving explicit revision and GITHUB_SHA precedence.

In `@core/builder/tensorrt_model_connect/bundle_writer.py`:
- Around line 209-213: Update the provenance serialization flow around
_provenance to encode the JSON into a local value, validate that value against
_MAX_HEADER_SIZE, and only assign it to _provenance after validation succeeds.
Preserve the ValueError for oversized provenance while ensuring a caught
exception cannot leave rejected data available for finish().

In `@families/gpt_oss/requirements.txt`:
- Line 1: Update the accelerate dependency pin from 1.14.0 to a patched release
that addresses GHSA-4j2p-28q2-5m79, preserving compatibility with the family’s
AutoModelForCausalLM.from_pretrained loading path.
- Line 1: Update the accelerate dependency pin from 1.14.0 to a release
containing the GHSA-4j2p-28q2-5m79 fix, ensuring the requirements no longer
allow version 1.14.0.

Require checkpoint identity in every BuildRequest.

The public core contract still permits empty checkpoint_id and checkpoint_revision values. Lines 264-265 then store a local path and "unknown" as provenance.

A direct build(BuildRequest(...)) call can therefore publish a bundle without reproducible checkpoint identity. Make both fields mandatory and reject empty values in __post_init__.

As per path instructions, “Treat core as model-agnostic contracts and mechanics.” Based on learnings, “core accepts checkpoint revisions only as exact 40-character Git SHAs or resolved provider version-object IDs in <provider>:version:<id> format.”

Do not resolve provenance from an unrelated enclosing repository.

If no explicit revision, TRTMC_ENGINE_BUILD_REVISION, or GITHUB_SHA is set, resolve_source_revision runs git -C from the package directory. Git searches parent directories, so an installed package inside another checkout can record that checkout’s HEAD as build.source_revision. Different package versions can therefore receive the same incorrect provenance. Verify that the discovered work tree owns the package source; otherwise require an embedded package revision or TRTMC_ENGINE_BUILD_REVISION.

Do not retain provenance after rejecting its size.

Line 209 assigns _provenance before Line 212 validates its size. If a caller catches the ValueError, finish() can write the oversized trailer. read_bundle_provenance() then rejects the published bundle.

Validate a local encoded value before assigning _provenance.

Proposed fix 
-        self._provenance = json.dumps(
+        provenance = json.dumps(
             value, ensure_ascii=False, separators=(",", ":")
         ).encode("utf-8")
-        if len(self._provenance) > _MAX_HEADER_SIZE:

             raise ValueError("bundle provenance exceeds the 100 MiB runtime limit")

The security advisory GHSA-4j2p-28q2-5m79 (also tracked as CVE-2026-69112) identifies a path traversal and denial-of-service vulnerability in Hugging Face Accelerate versions up to and including 1.14.0 [1][2][3]. The vulnerability exists in the load_checkpoint_in_model and load_checkpoint_and_dispatch functions [1][4]. These functions were found to improperly sanitize weight_map entries parsed from sharded checkpoint index files (*.index.json) [1][5]. Because these entries are joined to the checkpoint directory path without sufficient validation, a malicious or corrupted checkpoint index could force the library to open files outside of the intended directory using path traversal sequences (such as../) or absolute paths [5][6][7]. Furthermore, pointing shard entries to named pipes (FIFOs) could cause the loading process to block indefinitely, resulting in a denial-of-service condition [1][5][4]. To address this, patches were introduced in the Hugging Face Accelerate repository to strictly validate that resolved shard paths remain within the designated checkpoint folder [6][7]. This is achieved by normalizing the path and verifying that it does not escape the checkpoint directory; absolute paths are rejected [6][7]. Users are advised to upgrade to a version of Hugging Face Accelerate that incorporates these fixes to mitigate the risk of arbitrary file reads and potential denial-of-service attacks associated with loading untrusted checkpoints [1][3]. The fix was implemented in pull requests such as #4070 and #4138 [6][7].

Path Traversal

CWE: CWE-22 — Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Use a patched accelerate release.

accelerate==1.14.0 is affected by GHSA-4j2p-28q2-5m79. This family loads checkpoints with AutoModelForCausalLM.from_pretrained(..., low_cpu_mem_usage=True), which can reach the vulnerable Accelerate loading path. An attacker-controlled shard index can cause file reads outside the checkpoint directory or block on a named pipe. Replace this pin with a patched release, or validate every resolved shard path before loading.

GHSA-4j2p-28q2-5m79 Accelerate fixed version low_cpu_mem_usage load_checkpoint_in_model

💡 Result:

GHSA-4j2p-28q2-5m79 refers to a path traversal and denial of service (DoS) vulnerability affecting Hugging Face Accelerate versions up to and including 1.14.0 [1][2]. Vulnerability Summary: The vulnerability exists in the load_checkpoint_in_model and load_checkpoint_and_dispatch functions [1][3]. When these functions process sharded checkpoints, they fail to sanitize weight_map entries from the checkpoint's index JSON file [1][2]. An attacker can exploit this in two primary ways: 1. Path Traversal: By including../ sequences or absolute paths within the weight_map, an attacker can cause Accelerate to open files outside the intended checkpoint directory, potentially allowing for arbitrary file reading [3][2]. 2. Denial of Service (DoS): By pointing shard entries to named pipes (FIFOs) or other special files, an attacker can cause the loading process to hang indefinitely [3][2]. Fixed Version: The vulnerability was addressed in Hugging Face Accelerate by rejecting sharded weight_map paths that escape the designated checkpoint folder [3]. Users should update to a version of Accelerate released after the fix (which was implemented via pull requests #4070, #4131, and #4138) to remediate this issue [3][2]. As of the advisory, all versions through 1.14.0 are considered affected [1][2].

Denial of Service

Reachability: External
Exploitability: Moderate
CWE: CWE-400 — Uncontrolled Resource Consumption

Upgrade accelerate to a release that fixes GHSA-4j2p-28q2-5m79.

BuildRequest.model_dir selects the checkpoint, and load_weights enables low_cpu_mem_usage=True. This routes sharded loading through Accelerate, where a malicious weight_map can reference a named pipe and block the build worker indefinitely. Do not keep version 1.14.0.

Decode the bundle header as UTF-8 before parsing it. read_bundle_provenance passes raw bytes to json.loads, which accepts BOM-marked UTF-16/UTF-32 headers. Runtime BundleReader passes the same bytes to nlohmann JSON as std::string, which expects UTF-8 and rejects them. A matching-provenance bundle can therefore be marked reused by _bundle_matches_model and fail at runtime. Parse raw_header.decode("utf-8") and add a regression test.

Read bundle metadata and provenance from one file snapshot.

reader.info() and InspectBundleProvenance() open the bundle independently. If another process replaces the bundle between these operations, inspect can combine the header from one bundle with provenance from another bundle.

Expose one core API that returns both values from the same open file snapshot.

Do not infer checkpoint identity from a caller-supplied path name.

A local directory named snapshots/<40-hex> is accepted without --revision. Its contents can be arbitrary or modified. The bundle then records the directory name as an immutable checkpoint revision.

Track whether _resolve_model downloaded the snapshot. Permit path-based SHA inference only for that provider-resolved path. Require an explicit validated revision for every caller-supplied local directory.

Reject missing checkpoint revisions in BuildRequest.__post_init__. validate_checkpoint_revision rejects empty values, but the current guard skips validation. An exported direct caller can therefore write a bundle with checkpoint revision "unknown", which violates the immutable provenance required by the build path. Call validate_checkpoint_revision(self.checkpoint_revision) unconditionally.
