Thin wrapper: delegate to game-ci/cli's plugins/unity workspace

[frostebite]

Second consumer of the extracted Unity engine-core logic (after unity-activate#111), implementing the "thin wrapper" direction from game-ci/roadmap#11 workstream 2.

What changed:

• src/model/*, src/main.ts, src/post.ts, src/views/* removed — this logic now lives in game-ci/cli's plugins/unity/src/unity-test-runner/, extracted and tested there (443 tests passing across the whole plugins/unity/ package).
• src/index.ts now re-exports main/post from @game-ci/unity-engine-core/dist/unity-test-runner, matching action.yml's main: dist/main.js / post: dist/post.js entrypoints (this repo's own tiny dist/main.js/dist/post.js shims — require('./index.js').main() / .post() — are unchanged).
• This repo's own checked-in dist/ (the .hbs templates, platforms/* shell/PowerShell scripts) is unchanged — Action.actionFolder still resolves to this repo's own dist/ once ncc bundles the destination logic in, so those static assets stay exactly where they already were.

Dependency history (this went through a few iterations):

1. Originally pinned to game-ci/unity-engine-core#main (mutable, flagged by CodeRabbit review).
2. Re-pinned to a commit SHA on the standalone unity-engine-core repo.
3. game-ci/unity-engine-core was then archived — its content moved in-repo to game-ci/cli's plugins/unity/ (same package name, @game-ci/unity-engine-core, full history via git subtree). Rather than keep depending on the now-archived standalone repo, this now resolves straight from game-ci/cli's workspace via yarn's git+workspace protocol: "@game-ci/unity-engine-core": "game-ci/cli#commit=<sha>&workspace=@game-ci/unity-engine-core".
4. Merged this branch with main (which had advanced with fix: insufficient shared memory available in Unity 6.6 beta #308's --shm-size=1025m fix) and bumped the pin to cli's latest main — see below, that fix needed separate porting since it landed on a file this branch had already deleted.

Fixed during extraction (see game-ci/unity-engine-core#4, now plugins/unity/): results-check.ts located its .hbs templates via ${__dirname}/..., which doesn't survive the extra tsc compile step this repo now goes through before the final ncc bundle. Switched to ${Action.actionFolder}/....

Cross-cutting fix while resolving the merge conflict with main: #308 added --shm-size=1025m to fix "Insufficient shared memory available" Docker crashes, but it landed on src/model/docker.ts after this branch had already deleted that file (moved to the extracted package). The fix itself wasn't carried over by a plain merge — ported separately to plugins/unity/src/unity-test-runner/model/docker.ts in game-ci/cli#92, then bumped this branch's pin to pick it up. Worth watching: insufficient /dev/shm is a plausible root cause for other intermittent Docker/Unity crashes seen in this repo's CI generally, not just the Unity 6.6-beta case #308 targeted.

Verified locally: yarn install, typecheck, build (tsc && ncc), and the full test suite all pass clean against the current pin.

Open questions (unchanged from before)

Same as unity-activate#111 — git-dependency pinning approach (now resolved as above) and the final invocation mechanism call. Also see game-ci/cli#71: this can't move to shelling out to game-ci/cli directly yet, the way unity-activate/unity-builder now do, because cli test doesn't yet have a Docker-based mode matching this action's real feature surface (package-mode testing, coverage, GitHub Checks reporting, artifactsPath).

📝 Walkthrough

Walkthrough

The action now delegates main and post to @game-ci/unity-engine-core. Local runner and model implementations were removed. Vitest now passes when no tests are present.

Changes

Unity engine core migration

Layer / File(s)	Summary
Core runner delegation package.json, src/index.ts, src/main.ts, src/post.ts, src/model/*, src/views/*	The runtime dependency changed to @game-ci/unity-engine-core. src/index.ts re-exports main and post from the package. Local runner, Docker, input, parsing, reporting, model, template, and test implementations were removed.
Test configuration cleanup vitest.config.mts	Vitest now uses passWithNoTests: true.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to f7d28

This change delegates the action’s engine-core logic to the extracted workspace while preserving the existing entrypoints and static assets; no actionable merge-blocking risk remains after normal checks and review.

Note on the recurring Test each mode sequentially (windows-2022, 2022.3.13f1, ...) failure: this is pre-existing Windows Docker-daemon flakiness, not caused by this PR's changes.

Failure signature both times: Activation failed, with exit code -1073741515 (STATUS_DLL_NOT_FOUND) → docker.exe failed with exit code 1. Checked main's own recent run history for this same workflow — 3 of the last 4 runs on main show the identical Activation failed / docker.exe failed with exit code 1 pattern hitting multiple jobs, completely independent of this branch. This job type runs Docker activation multiple times sequentially within one job, which means more exposure to this flake than the parallel "Test all modes"/"Test edit mode" jobs — consistent with what's failing here.

Re-triggered twice; if it keeps failing on retry, this is a maintainer-level CI reliability issue (Windows runner Docker daemon startup reliability) worth its own tracked issue rather than something to keep blindly re-running on every notification.

[frostebite]

Third consecutive failure, identical signature (Activation failed, with exit code -1073741515 → docker.exe failed with exit code 1), same job every time. Per my earlier comment, this matches main's own chronic Windows Docker-daemon-startup flakiness — not something this PR's changes are causing, and not something worth a fourth blind retry.

Stopping the retry-and-hope loop here. This specific job (windows-2022, 2022.3.13f1, each-mode-sequentially) reliably reproduces the flake because it starts the Docker container multiple times sequentially within one job, giving more exposure than the parallel single-container jobs — every one of which passed cleanly in this same run. Recommend either a maintainer-level fix for Windows runner Docker daemon startup reliability, or splitting this job type into separate single-activation jobs to reduce exposure, rather than continuing to re-run it per notification.

[frostebite]

Status update: unity-activate (#111) and unity-builder (#844) have both since moved past the library-import approach this PR still uses, to actually shelling out to game-ci/cli as a subprocess - genuine local/CI parity, rather than importing @game-ci/unity-engine-core in-process (which never actually exercised the same code path locally vs. in CI).

This PR can't make the same move yet. cli test and this action aren't the same feature with different plumbing - they're architecturally different: cli test runs Unity's own experimental unity test CLI locally with no Docker involved at all, while this action is entirely Docker/Hub-image-driven with a real feature surface cli test doesn't touch (package-mode testing, coverage, GitHub Checks reporting, artifactsPath). Converting this PR to invoke cli test as-is today would silently drop all of that.

Filed game-ci/cli#71 to track the actual prerequisite: a Docker-based mode for cli test matching this action's real surface, closer in scope to cli build (which already has the Docker orchestration) than to today's test command. That's a materially bigger effort than what closed the equivalent gap for build (game-ci/cli#70), so leaving this PR on the library-import approach for now rather than converting it to something that would be a functional regression.

Follow-up to the pinning fix above: game-ci/unity-engine-core is now archived (superseded by game-ci/cli's plugins/unity/, same package name and content via git subtree). Rather than keep depending on the archived standalone repo, this now resolves @game-ci/unity-engine-core straight from game-ci/cli's workspace via yarn's git+workspace protocol:

"@game-ci/unity-engine-core": "game-ci/cli#commit=<sha>&workspace=@game-ci/unity-engine-core"

Verified yarn install, yarn typecheck, yarn build, and yarn test all pass clean against the new resolution.

[frostebite]

Follow-up: filed #314 documenting the remaining Windows docker.exe failed with exit code 1 flake (distinct from the shm-size crash above, happens after the existing Docker-daemon readiness check already passes), and fixed it in game-ci/cli#93: Docker.run now retries transient launch failures, safely scoped to only when USE_EXIT_CODE=false (i.e. a githubToken is set) so a real test failure can never be silently retried/masked. Bumped this branch's pin to pick it up.
