ci: fix cache-save hang and add dist drift check - #96
Conversation
Split the yarn install cache actions/cache@v4 step into explicit restore/save steps so a hung post-run cache-save can no longer block the job. The save step now runs at the end with a 5-minute timeout and continue-on-error so it can never fail or hang the job. Also add a "Verify dist is up to date" step so committed dist/ (built via tsc && ncc build) can't silently drift from src/, modeled on the equivalent check in game-ci/cli's tests.yml. Bonus: add timeout-minutes to the checkEnv and updateMajorTag jobs, which previously had none.

The new "Verify dist is up to date" check (added earlier in this PR) correctly caught this: the committed dist/index.js was stale relative to the current yarn.lock (a tslib helper-block difference from ncc's bundling), predating this PR. Rebuilt with the exact node/yarn versions pinned in mise.toml (node 20.18.0, yarn 4.14.1 via corepack) to match what CI actually produces. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
ncc/esbuild's platform-specific binaries produce a genuinely different bundle on Windows vs the linux-x64 CI runner, even with matching node/yarn versions - the previous commit's Windows-built dist still didn't match what CI itself produces. Downloaded the actual CI-built dist/ via a temporary artifact-upload step and committed it byte-exact instead, then removed that temporary step. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
if: always() runs the cache-save step even after a cancelled workflow run, which actions/cache/save@v4 doesn't handle cleanly. Use !cancelled() instead - still saves after an ordinary step failure, just not after cancellation. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
GitHub is deprecating Node.js 20 on Actions runners and force-running node20 actions on Node 24 anyway in the meantime. Matches the same one-line bump already shipped in the sibling actions: game-ci/unity- test-runner#304 and game-ci/unity-builder#827. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Without a token, this step's `game-ci` CLI download resolves cliVersion "latest" via an unauthenticated GitHub API call. GitHub-hosted runners share IPs across many concurrent jobs from unrelated repos/orgs, so the 60 req/hour anonymous rate limit gets exhausted by traffic this job never generated - hit live on this PR's own CI just now: "Failed to resolve the latest game-ci CLI release: GitHub API returned 403." download-cli.ts already reads GITHUB_TOKEN/GH_TOKEN and adds an Authorization header when present (lifting the limit to 5000 req/hour) - it just never receives one from this workflow. Passing github.token through fixes it without touching the action's own code. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

💡 Result:
In GitHub Actions, the GITHUB_TOKEN is a unique authentication token created for each workflow job [1]. Its default permissions are determined by settings configured at the organization or repository level, which administrators can set to either read or write [2]. When you define a permissions key within your workflow file, you explicitly control the access granted to the GITHUB_TOKEN [3][4]. It is important to note that if you specify any permission within the permissions block, all other unspecified permissions are automatically set to none [4][5]. For example, if you wish to set contents to read access while leaving other permissions as none, you must explicitly declare it: permissions: contents: read If you do not include a permissions key in your workflow, the GITHUB_TOKEN defaults to the permissions level (read or write) configured in your organization or repository settings [2]. Because of this, GitHub recommends adopting the principle of least privilege by explicitly defining the minimum required permissions for every workflow to mitigate security risks [3][6]. If your workflow requires multiple permissions, you must list all of them, as omitting any will set them to none [4][5].

Security Misconfiguration
Reachability: Internal
Exploitability: Difficult
CWE: CWE-250
Restrict the token before passing it to the action.
testDeploy has no explicit permissions: policy, so github.token uses repository or organization defaults. Add job-level contents: read permissions before exposing the token at both action steps.
