📝 Walkthrough

Walkthrough

The CI workflow removes optional inputs, resolves shared Scala and sbt values, and runs coverage, binary compatibility, formatting, and Scaladoc checks in separate matrix jobs. The README and release workflow describe the updated commands and workflow version.

Changes

CI validation workflow

Layer / File(s) Summary
Shared version and task resolution
.github/workflows/ci.yml, README.md
The workflow removes optional check inputs and publishes resolved Scala versions and sbt task outputs for downstream jobs. The README documents the v6.4.0 workflow and concurrent checks.
Dedicated coverage pipeline
.github/workflows/ci.yml
The coverage matrix job runs clean, coverage, tests, aggregation, report validation, and upload without a coverage input.
Independent validation checks
.github/workflows/ci.yml
Dedicated matrix jobs run binary compatibility, formatting, and Scaladoc checks. The SonarQube scan action changes from v8.2 to v8.
Release workflow and setup documentation
.github/workflows/release.yml, README.md
The release cache step receives an explicit name. Release setup examples use updated sbt commands and aliases.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 74f04

The workflow changes may break existing reusable-workflow callers by removing documented inputs, while the README currently shows a trigger that does not match the example configuration. These compatibility and documentation issues should be corrected or explicitly accepted before merging.

30-30: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Preserve the reusable-workflow input schema.

The README documents these inputs and uses version_policy_check in its example. When a caller passes a removed input, GitHub rejects the workflow call before jobs start. Keep deprecated no-op inputs during migration, or publish a breaking release with migration guidance.

199-204: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Remove the unused sbt-tasks dependencies.

binary-compatibility and formatting only use needs.scala-versions.outputs.version. They do not consume an output from sbt-tasks. Keeping this dependency delays both jobs and reduces the concurrency requested by this PR.

Proposed change
-    needs: [scala-versions, sbt-tasks]
+    needs: [scala-versions]

Also applies to: 228-233

Inline comments:
In @.github/workflows/ci.yml:
- Line 63: Update the reusable workflow input handling around the versions
output step and task execution blocks: validate scala_versions as an allowlisted
JSON array before shell interpolation, and restrict test_task and clean_task to
approved sbt task values before using them in run commands. Reject invalid
inputs before execution while preserving the existing behavior for valid values.
- Around line 72-73: Update all five actions/checkout steps in the workflow to
set persist-credentials to false, including the checkout step identified by name
checkout; preserve their existing checkout configuration and other settings.

In `@README.md`:
- Line 77: Update the README wording in the versionPolicyCheck task description
from “fully checked out repo” to “fully checked-out repository,” preserving the
rest of the sentence.
- Around line 3-5: Update the Scala Continuous Integration workflow description
to match the example trigger configuration: state that it runs on pushes to
master and on pull requests, rather than on every push.
- Around line 65-69: Update the “jobs in CI pipeline” README section to qualify
its concurrency statement: explain that validation jobs run concurrently only
after the shared scala-versions and sbt-tasks resolution jobs complete, rather
than claiming all workflow jobs start concurrently.
- Around line 123-128: Update the README setup text around the sbt command
aliases to remove the stale Scalafix reference, while preserving the existing
sbt-version-policy link and alias documentation.
