Hey @leynos - I've reviewed your changes and found some issues that need to be addressed.
- Instead of matching on the debug-formatted error string for MissingField("reference"), consider adding a dedicated variant or helper in OrthoError to detect missing reference fields more robustly.
- The fallback match logic for PR and Issue args is duplicated; extract it into a shared helper function to reduce repetition in main.rs.

The match statement has more than two branches and should be refactored into a predicate function.
To adhere to the instruction, please extract the multi-branch match logic into a separate predicate function for clarity and maintainability.

3-3: Verify public exports ofGatheringErrorinortho_config
The grep didn’t locate apub enum GatheringErroror its variants in theortho_configcrate. Ensure the error type and its variants are publicly exposed so that calling crates can pattern-match on them.
- Inspect the
ortho_configcrate’s source (e.g.src/lib.rsor the module definingGatheringError) and confirm it contains:pub enum GatheringError { MissingField(String), // … }- If
GatheringErroris defined in a submodule, add apub useinlib.rsto re-export it:pub use gathering::GatheringError;- After exposing the enum, update the import in
src/main.rsas needed:use ortho_config::{OrthoConfig, OrthoError, GatheringError, /* … */};README.md (1)
28-31: Documentation accurately describes the new fallback behaviour.The explanation clearly communicates that missing reference fields in configuration will gracefully fall back to CLI arguments rather than causing the tool to exit with an error. This aligns perfectly with the implementation changes.

3-4: LGTM! Imports support proper error handling.The new imports enable robust pattern matching on configuration errors, replacing the fragile string matching approach mentioned in past reviews.
695-695: LGTM! Consistent application of fallback behaviour.The changes correctly replace direct config loading with the new fallback function for both command types, addressing the fragile string matching issues from past reviews.
Also applies to: 699-699

🧹 Nitpick (assertive)
Avoid unnecessary cloning in error iteration.
The function correctly uses pattern matching instead of fragile string matching, addressing past review concerns. However, cloning the error for iteration is inefficient.
Apply this diff to avoid cloning:
-fn missing_reference(err: &FigmentError) -> bool {
- err.clone()
- .into_iter()
- .any(|e| matches!(e.kind, FigmentKind::MissingField(ref f) if f == "reference"))
-}
+fn missing_reference(err: &FigmentError) -> bool {
+ err.iter()
+ .any(|e| matches!(e.kind, FigmentKind::MissingField(ref f) if f == "reference"))
+}Committable suggestion skipped: line range outside the PR's diff.

In src/main.rs around lines 670 to 674, the function missing_reference clones
the error before iterating, which is inefficient. Modify the function to iterate
over references to the error without cloning it, by using a method like iter()
or as_ref() on the error to avoid unnecessary cloning while preserving the
pattern matching logic.

Fix coding guideline violations.
The function has two violations of the coding guidelines:
- Multi-branch conditional: The match statement has >2 branches and must be refactored into a predicate function per coding guidelines.
- Forbidden #[allow] attribute: Replace with narrowly scoped #[expect] with reason.
Apply this diff to address the violations:
+fn should_fallback_to_cli(result: &Result<(), OrthoError>) -> bool {
+ matches!(result, Err(OrthoError::Gathering(e)) if missing_reference(e))
+}
+
-#[allow(clippy::result_large_err)]
+#[expect(clippy::result_large_err, reason = "OrthoError size is determined by ortho_config crate")]

In src/main.rs around lines 675 to 685, refactor the match statement in
load_with_reference_fallback to eliminate the multi-branch conditional by
extracting the error condition into a separate predicate function that checks if
the error is a Gathering error with a missing reference. Also, remove the broad
#[allow(clippy::result_large_err)] attribute and replace it with a narrowly
scoped #[expect] attribute on the specific line or expression causing the lint,
including a reason for the expectation.

Summary by Sourcery
Use match to catch missing reference defaults during subcommand configuration merging and fall back to CLI-provided values instead of erroring out, and document this behavior in the README.
