ci: report Skipped instead of a green check when Unity tests cannot run - #1362
Conversation
Both Unity workflows gated every step on a step-level `if:` reading an in-job license-detection output. A step-level `if:` yields step-conclusion `skipped`, which contributes nothing to the job conclusion -- so on any fork PR, where GitHub withholds the UNITY_* secrets, the jobs reported a green check having compiled nothing and booted no Editor. Both workflows already said so in their own comments and step summaries, but a step summary is not what the merge box shows, and reviewers read the tick. Hoists detection into a `license` gate job and gates the real job on it with a job-level `if:`. A job skipped that way reports "Skipped" in the merge box. Branch protection treats a skipped required check as satisfied, so this does not block merges -- it only stops the check claiming a pass it never earned. Also documents which checks are real signal on a fork PR, and drops the stale `safe-to-test` references from the contributor docs (that gate was retired in CoplayDev#1308).

Self-review — the fix is confirmed by this PR's own checks (it comes from a fork, so it exercises exactly the case in question): One caveat worth checking before merge, which I did not anticipate and only saw in the result above. A matrix job skipped by a job-level So the check name is no longer stable between the run and skip cases. If Two options:
Happy to push option 2 if you tell me which it is. |

Pull request overview
This PR adjusts the GitHub Actions Unity workflows so that fork PRs without Unity license secrets show Skipped (via job-level if: gating) instead of reporting a misleading green success when no Unity compile/tests actually ran. It also updates contributor documentation to clarify which CI checks provide real signal on fork PRs.
Changes:
- Hoists Unity license detection into a dedicated
licensegate job and uses job-levelif:to skip Unity test/e2e jobs when secrets aren’t available. - Updates the Unity tests workflow to remove step-level gating now that the entire job is gated.
- Documents which CI checks are meaningful on fork PRs and how maintainers can run the full Unity suite in a trusted context.

From review feedback on this PR: - The unity-tests pull_request trigger is path-filtered, so 'Every PR gets a unity-tests status check' overstated it. A PR touching only Server/** or docs never creates the check. - The full-matrix section told contributors the label takes effect on the next pull_request OR pull_request_target event. unity-tests.yml deliberately has no pull_request_target trigger (line 31 says so), so half that sentence pointed at an event that never fires. - 'licence'/'Licence-free' -> 'license', matching UNITY_LICENSE and the rest of the guide.
Both Unity workflows have been reporting a green check having run nothing on every fork PR. Since practically every PR to this repo comes from a fork, that is most of the queue.
The mechanism
Both gate every real step on a step-level
if:reading an in-job license-detection output:A step-level
if:yields step-conclusionskipped, which contributes nothing to the job conclusion. So the job exits clean and the merge box shows a tick.Both workflows already knew. From their own source, before this PR:
The step summary does say so. But a step summary is not what a reviewer scans — the tick is.
What it looked like in practice
PR #1323 does not compile.
SkyboxOps.cs(18,17): error CS0266, red on all three OS since 2026-08-15. Here is how it presents:Five green ticks on a PR that provably does not build. The same shape appears on #1285, #1287 and #1043, where the two hollow ticks are 100% of their green.
The fix
Hoist detection into a
licensegate job and gate the real job on it with a job-levelif::A job skipped by a job-level
if:reports Skipped in the merge box, which is visually distinct from a pass. Branch protection treats a skipped required check as satisfied, so this does not block merges — it only stops the check claiming a pass it never earned.No change to what runs when secrets are in scope: same steps, same
actions/cachekey, same matrix, same artifacts.Also

pushtrigger runs the full suite in a trusted context. (There is deliberately nopull_request_targetfor these — fork-authored C# plusUNITY_*secrets is the classic "pwn request" shape.)Drops the stale

Both files validate as YAML and the job graph is as intended (
