How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 WalkthroughWalkthroughThe 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. ChangesCI validation workflow
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to The workflow now runs pipeline steps concurrently while preserving its reusable inputs, but caller-controlled values still need validation, checkout credentials still need hardening, and the README trigger example remains inconsistent. The PR is mergeable with explicit owner awareness of these bounded follow-ups. Sequence Diagram(s)sequenceDiagram

- 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.

Validate reusable workflow inputs before shell interpolation.
No local workflow calls ci.yml, so caller trust is not established. A caller-controlled scala_versions value can terminate the single-quoted command at line 63. test_task and clean_task can inject sbt commands when interpolated into later run blocks. Validate scala_versions as an allowlisted JSON array and restrict both task inputs to approved sbt tasks.
