- Around line 293-296: Update the webapp-e2e PostgreSQL image selection branch
around the docker pull/tag commands to handle absent base-SHA tags: either fall
back to an available published PostgreSQL image tag when the pull fails, or
restrict execution to base branches guaranteed to publish images. Preserve the
existing postgres_image_changed behavior and ensure the job can start PostgreSQL
without failing on pull requests targeting unsupported branches.

Handle missing PostgreSQL base-image tags.
webapp-e2e enters the docker pull branch when inputs.postgres_image_changed is false. The Docker workflow publishes ${{ github.sha }} tags for push events to main, but pull requests may target any branch. If the base branch was not processed by that publisher, the base-SHA tag is absent, docker pull fails, and the E2E job stops before PostgreSQL starts.
Add a fallback for a missing tag or restrict this workflow to base branches with published images.

dorny/test-reporter v3.0.0 action.yml required inputs name path reporter
💡 Result:
In the action.yml configuration for dorny/test-reporter version 3.0.0, the inputs name, path, and reporter are all marked as required [1][2]. The input requirements are defined as follows: name: Required (true). Defines the name of the check run [1][2]. path: Required (true). Specifies the comma-separated list of paths to test results [1][2]. reporter: Required (true). Specifies the format of the test results (e.g., java-junit, jest-junit, python-xunit) [1][2].

Description
Cuts redundant work from pull-request CI by building the server reactor and Storybook once, then reusing those outputs in downstream checks. It also separates tooling and documentation checks from server validation, reuses the published PostgreSQL image when its source is unchanged, and extends Playwright caching to end-to-end tests.
Addresses #1590. The issue should remain open until the required post-landing sample confirms a p50 verdict of at most seven minutes across at least ten runs.
What changed

This PR intentionally does not implement dependency-install caching; #1598 and #1591 own the pnpm store and setup composite. Hosted CI must still provide two pieces of evidence before #1590 is complete:
