including the symbols at the referenced action lines, from mutable version tags
to the reviewed full immutable commit SHA; retain each original release tag as
an adjacent comment.
- Around line 27-28: Update the BRANCH_NAME and TAG_NAME assignments in the

TAG_NAME to GITHUB_ENV, normalize slashes and any other Docker-tag-invalid
characters into valid tag characters so distinct branches cannot collide.

- Line 24: Update the platform cache options in set_property for platform,
replacing the misspelled Snitc value with Snitch while preserving all other

In `@Container/Dockerfile.xheep`:
- Line 5: Pin the BASE_IMAGE default in Container/Dockerfile.xheep line 5 to an
immutable sha256 digest instead of the mutable main tag. Update
.github/workflows/docker-build-deeploy-xheep.yml line 14 to use the identical
digest, keeping both build defaults aligned.
In `@Deeploy/Targets/Generic/Bindings.py`:
- Line 432: Correct the operator binding arities in
Deeploy/Targets/Generic/Bindings.py:432-432 by configuring TanhChecker with one
float input, and in Deeploy/Targets/Generic/Bindings.py:438-441 configure
ReduceMaxChecker with one IntegerDataTypes input while removing the unused
second-type loop. Preserve the existing output types and templates.
In `@Deeploy/Targets/Generic/Parsers.py`:
- Line 3209: Update the ReduceMax axis handling to require exactly one axis,
reject empty or out-of-range values, and normalize negative axes against
len(data_in.shape) before calculating inner_size and output_size. Apply this in
the axis parsing and size-calculation flow, preserving the normalized value in
self.operatorRepresentation['axes'].
In `@Deeploy/Targets/Generic/Templates/TanhTemplate.py`:
- Line 19: Add math.h to the X-HEEP includeList alongside DeeployBasicMath.h and
csr.h, ensuring generated sources declare tanh while preserving the existing
toolchain configuration.
In `@Deeploy/Targets/Generic/TopologyOptimizationPasses/Passes.py`:
- Line 1206: Update the unrolled Concat construction to derive a unique base
name from concat_node.name instead of the fixed name value, and use that base
consistently for the intermediate tensor and all three replacement objects.
Preserve the existing naming suffixes while ensuring separate Concat nodes
cannot produce duplicate graph identifiers.
In `@DeeployTest/deeployRunner_xheep.py`:
- Around line 17-23: Update setup_xheep_defaults to use environment-backed or
checkout-relative defaults instead of hard-coded /app/install/riscv and
/app/x-heep paths, while preserving caller overrides from
--toolchain-install-dir and -D XHEEP_HOME. Before configuring CMake, validate
the resolved toolchain and X-HEEP paths and fail clearly if they do not exist.
In `@DeeployTest/Platforms/Xheep/main.c`:
- Around line 69-70: Include inttypes.h and update the printf calls in main to
use fixed-width format macros for the uint32_t counters tot and timer_val,
preserving the existing messages while avoiding signed integer format
specifiers.

Preserve the full ref name when creating the Docker tag.
${GITHUB_REF##*/} keeps only the final path segment. Both feature/xheep and release/xheep produce the xheep image tag. A later manual build can overwrite the wrong image.
Use GITHUB_REF_NAME. Normalize / and other Docker-tag-invalid characters before writing the value to GITHUB_ENV.

Yeah, this is a good practice; otherwise, you can end up overwriting a tag without wanting to

Seems like the humans are having a chat. I'll hop back into my burrow for now. If you need me again, just tag @coderabbitai in a new comment, and I'll come hopping out!

In @.github/workflows/_runner-xheep.yml:
- Line 30: Replace the mutable version tags for the external actions in the
workflow, including actions/checkout and actions/cache/restore, with trusted
full commit SHA pins. Update every affected occurrence while preserving the
existing action versions and workflow behavior.
- Line 65: Update the “Run Test” workflow step to pass inputs.pytest-marker
through the step’s env as PYTEST_MARKER, then use "$PYTEST_MARKER" in the pytest
-m expression instead of interpolating the input directly into the Bash script.
- Line 25: Update the job container image configuration using the docker-image
input so it only accepts immutable `@sha256` digest references or approved
immutable image values; reject unrestricted tags or other mutable references
while preserving the existing container setup.
In `@Deeploy/Targets/Generic/TypeCheckers.py`:
- Around line 641-647: Update ReduceMax’s _inferNumLevels and _inferSignedness
methods to propagate metadata from inputs[0], returning its nLevels and _signed
values instead of deriving constants from input_types or forcing signedness to
true.
In `@DeeployTest/test_xheep_config.py`:
- Around line 8-11: Update the platform test configuration to import
KERNEL_TESTS from test_xheep_config.py and add an xheep entry to
PLATFORM_CONFIGS so the X-HEEP kernel tests are scheduled by the runner.

Honor the supplied X-HEEP toolchain directory.
The X-HEEP test receives toolchain_dir, but this call discards it and always configures /app/install/riscv. Use the supplied directory and keep /app/install/riscv as the fallback.
Proposed fix
- toolchain_dir="/app/install/riscv",
+ toolchain_dir=toolchain_dir or "/app/install/riscv",📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
