Summary by CodeRabbit

  • Chores
    • Updated the changelog with details for version 1.3.5.
    • Improved the handling of coverage baseline caching and ratcheting in the GitHub action, ensuring coverage checks occur after all relevant results are available and optimising cache key usage.

Walkthrough

Update the GitHub Action workflow for coverage generation by moving the ratchet coverage and baseline saving steps to execute after both Rust and Python coverage results are available. Add a changelog entry documenting this adjustment in step ordering. No changes to logic or exported entities are introduced.

129-146: Set strict shell options—nice

set -euo pipefail hardens the ratchet step and resolves the earlier robustness concern. No additional issues spotted here.


148-155: Constant cache key prevents quota bloat—good

Switching the save-baseline key to a fixed value implements the earlier recommendation and stops unbounded cache entries.

51-59: Align cache restore with save-key pattern

The restore step never hits the cache because the save step appends ${{ github.run_id }} while the restore key is static. Amend the restore step to use the prefix-match mechanism, so the most recent baseline is restored.

-    key: ratchet-baseline-${{ runner.os }}
+    key: ratchet-baseline-${{ runner.os }}-${{ github.run_id }}
+    restore-keys: ratchet-baseline-${{ runner.os }}-
