In @.github/workflows/build.yml:
- Around line 46-50: The workflow currently sets arch: arm64 but uses runner:
ubuntu-latest (which runs x64); update the runner value to the ARM-specific
label (use runner: ubuntu-24.04-arm) so the job actually executes on ARM64—leave
the existing arch: arm64 and other keys (e.g., catboost_version) intact and only
change the runner field.
In `@src/model.rs`:
- Around line 379-382: The test currently bails out silently when tmp/model.cbm
is missing, which masks missing zero-copy coverage; update the test that checks
model_path to instead ensure the fixture is available or explicitly fail—either
add setup code to create or copy the required tmp/model.cbm before calling
load_buffer_zero_copy, or replace the early return with a panic/assert that
model_path exists so the test fails when the fixture is absent; reference the
model_path variable and the load_buffer_zero_copy call in src/model.rs when
making the change.

Silent test skip can mask missing zero-copy coverage
The test at line 379-382 silently returns without failing when tmp/model.cbm does not exist. Since no fixture file is present in the repository and no setup code creates it, this test will always skip, allowing CI to pass without actually exercising the load_buffer_zero_copy code path.
Either ensure the fixture file is available during test execution or explicitly fail the test if it's required for coverage.

matrix.catboost_version, allowing different CatBoost versions to reuse cachedtarget/artifacts. This masks configuration-specific rebuild issues when switching between versions (e.g., from 1.2.8 to 1.2.10). Add the version to both the cache key and restore keys.Suggested workflow diff

In `@examples/advanced_usage.rs`:
- Around line 20-27: The example calls Model::load_buffer_zero_copy which is
cfg-gated; update the example to either gate it with #[cfg(catboost_zero_copy)]
or add a cfg-based fallback that uses Model::load() when the feature is absent,
and simplify file reading by replacing the manual buffer_res check with
idiomatic error propagation (use the ? operator or map_err to convert fs::read
errors into the example's CatBoostError) so you read the file into a buffer and
then call either Model::load_buffer_zero_copy(buffer) under
cfg(catboost_zero_copy) or Model::load(buffer) otherwise.
In `@examples/basic_usage.rs`:
- Around line 23-29: The example unconditionally calls the cfg-gated
Model::load_buffer_zero_copy which fails when that feature is disabled; change
the example to conditionally use load_buffer_zero_copy only when the
corresponding cfg/feature is enabled and fall back to the non-gated API
otherwise. Specifically, wrap the call site that reads fs::read into buffer_res
and the subsequent Model::load_buffer_zero_copy(buffer_res.unwrap()) call with
an #[cfg(feature = "...")] (or #[cfg(any(...))] matching the crate's gating)
branch and provide an #[cfg(not(feature = "..."))] branch that uses the
alternative Model::load_buffer(...) or other supported loading function, keeping
the same error handling around buffer_res.
- Around line 16-18: The error string in the CatBoostError construction is using
a `{}` placeholder but is not formatted; change the description assignment in
the Err(CatBoostError { description: ... }) to use format!(...) so the actual
model path variable (e.g., model_path) is interpolated into the message (e.g.
format!("No model file found at {}. Creating a simple example..", model_path))
so the description field contains the real path.
