Issue being fixed or feature implemented

The Kotlin AAR, Swift xcframework, and JavaScript/WASM package builds are the slowest parts of a Platform release. They run cold on GitHub-hosted runners on every release. In recent releases the NPM job spent about 50 minutes building and less than one minute publishing, while the Swift job repeatedly hit its hosted 45-minute timeout and left releases without DashSDKFFI assets.

What was done?

Moved the expensive release builds onto the persistent self-hosted runners already used by their PR-CI siblings:

  • release-kotlin-sdk.yml / build-and-release: ubuntu-24.04[self-hosted, kotlin-ci]
  • release-swift-sdk.yml / build-and-release: macos-15[self-hosted, macOS, ARM64]
  • release.yml: split the NPM release into:
    • build-npm on [self-hosted, kotlin-ci], which builds and uploads js-build-${{ github.sha }}
    • release-npm on ubuntu-24.04, which restores that artifact and performs only the trusted publish

The NPM publish remains GitHub-hosted because npm trusted publishing currently rejects self-hosted runners. The workflow filename and OIDC trust relationship are unchanged.

Adaptations for persistent hosts:

  • Idempotent dependency and tool checks replace hosted-image assumptions.
  • Release builds start from a pristine tracked tree while preserving Cargo target/ caches.
  • Persistent Cargo registry/target state replaces redundant Actions Cargo caches.
  • Tool versions are pinned (cargo-ndk 4.1.2, wasm-bindgen-cli 0.2.108, wasm-pack 0.15.0, protoc 32.0, Binaryen 121).
  • The NPM build receives no repository secrets and explicitly has no id-token permission. Its only Docker dependency is the public protoc image.
  • The JS artifact is retained for seven days so a failed hosted publish can be retried without rebuilding.
  • Swift timeout increases from 45 to 90 minutes to cover the first cold self-hosted run.

Left on hosted runners deliberately:

  • NPM trusted publishing, because npm does not support self-hosted GitHub Actions runners for OIDC trusted publishing.
  • maven-central-deploy, so environment-scoped Maven/GPG secrets never reach a persistent machine.
  • Docker image builds and Dashmate packaging; there is not yet a dedicated self-hosted Linux amd64+arm64 release fleet, and the signing/publishing jobs carry high-value credentials.

Security notes

  • These workflows run only for published releases or maintainer dispatches, never fork pull requests.
  • The self-hosted NPM build has contents: read, no OIDC token, and no repository secrets.
  • The hosted NPM job alone receives id-token: write and runs npm publish.
  • Release artifacts now share persistent build state with trusted PR-CI builds on the same machines. Periodic runner cleaning/reimaging remains the mitigation for that accepted warm-cache trade-off.

How Has This Been Tested?

  • actionlint schema/expression validation and YAML parsing pass for the changed workflows; changed shell snippets are ShellCheck-clean.
  • Verified the js-build-${{ github.sha }} artifact from the v4.2.0-dev.7 release extracts directly beneath packages/, matching the new hosted publish handoff and existing CI consumers.
  • Kotlin self-hosted release test against v4.2.0-dev.7: success in 12m 40s.
  • Swift self-hosted release test against v4.2.0-dev.7: success in 20m 23s, producing the xcframework the hosted job could not finish in 45 minutes.
  • NPM split-release rehearsal against v4.2.0-dev.7: success. The self-hosted build and artifact upload completed in 36m 29s; the hosted artifact download and dry-run publish completed in 37s. The real publish step and all unrelated release jobs were skipped.

Breaking Changes

None for consumers. Operationally, the NPM and Kotlin release builds share the kotlin-ci runner and may queue behind one another.

Summary by CodeRabbit

  • New Features

    • Added support for NPM release dry runs using npm-test: tags, preventing production publishing and related package or image releases.
    • NPM builds and publishing now run as separate stages, with build artifacts retained for up to seven days.
  • Improvements

    • Kotlin and Swift SDK releases now use persistent build environments and improved caching for more efficient, reliable releases.
    • Added tool version checks to improve release consistency.

The Kotlin AAR and Swift xcframework builds are the slowest parts of the platform release and were running cold on hosted runners. Move them to the same persistent runners their PR CI siblings use (kotlin-ci and the macOS ARM64 box) so they reuse warm cargo caches, and adapt the jobs to persistent hosts: idempotent dependency checks instead of hosted-image assumptions, pinned cargo-ndk, cache-preserving git clean, and no hosted-image disk-space pruning. The maven-central-deploy job stays on a hosted runner so environment-scoped publishing secrets never reach the persistent machines.

📝 Walkthrough

Walkthrough

The release workflows move Kotlin and Swift SDK builds to persistent runners. The NPM workflow separates package building from publishing, transfers packages through an artifact, supports npm-test: dry runs, and skips unrelated release jobs for those tags.

Changes

SDK persistent runner migration

Layer / File(s) Summary
Kotlin persistent runner setup
.github/workflows/release-kotlin-sdk.yml
The Kotlin SDK job uses kotlin-ci, installs missing dependencies, preserves the Rust target/ cache, verifies JDK 17, and pins cargo-ndk and protoc versions.
Swift persistent runner setup
.github/workflows/release-swift-sdk.yml
The Swift SDK job uses a persistent ARM64 macOS runner, preserves Cargo targets, restores the registry cache, uses the runner's default Xcode, and prunes architecture intermediates.

NPM release pipeline

Layer / File(s) Summary
NPM build job
.github/workflows/release.yml
A new build-npm job builds packages on kotlin-ci and uploads the js-build-${{ github.sha }} artifact with seven-day retention.
NPM artifact publishing
.github/workflows/release.yml
release-npm downloads the artifact, validates dispatch tags, publishes on release events, and runs npm publish --dry-run for npm-test: dispatches.
NPM-only release gating
.github/workflows/release.yml
Image and Dashmate package jobs skip execution when the dispatched tag starts with npm-test:.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟠 High · up to f9723

The PR moves release builds onto persistent self-hosted runners, but normal dispatches can skip the NPM dependency chain and prevent Dashmate packages from being produced, while mutable actions and leftover Git hooks can allow prior runner state to affect later release checkouts. These release-integrity and security risks should be fixed before merging.

actions/checkout v4 clean false existing .git post-checkout hook git checkout behavior

💡 Result:

In actions/checkout v4, the clean: false input instructs the action to skip the git clean -ffdx && git reset --hard HEAD command that normally runs before fetching [1][2]. This setting does not affect the standard operation of subsequent git checkout or git switch operations initiated by the action [3]. Regarding post-checkout hooks: 1. Triggering: The post-checkout hook is natively triggered by Git whenever a git checkout or git switch command successfully updates the working tree [4]. If actions/checkout performs a checkout operation, any correctly configured and executable post-checkout hook present in the repository's .git/hooks directory will be executed by Git [4]. 2. Behavior with existing .git: If you are using clean: false with an existing .git directory, the action will still attempt to prepare the repository for the requested ref [3]. If this process involves a Git command that updates the working tree (e.g., git checkout or git fetch followed by a reset/switch), the post-checkout hook will execute as per standard Git behavior [4]. 3. Execution Context: Note that GitHub Actions runners often have specific environment configurations. Ensure that your hook script is executable (e.g., chmod +x .git/hooks/post-checkout) and that its dependencies (like interpreters or path variables) are available within the runner's environment, as Git hooks do not automatically inherit the full environment of the CI job. In summary, clean: false simply prevents the action from proactively wiping your directory, but it does not disable Git's internal hook mechanisms. If the action's internal logic performs a checkout that triggers the hook, the hook will run [4].

Remove persisted Git metadata before the credentialed checkout.

clean: false preserves .git/hooks on both persistent self-hosted runners. A pull request job can leave an executable post-checkout hook in the workspace. actions/checkout can trigger that hook with the release job token before the later cleanup step. Delete .git before checkout, or use a fresh worktree outside the persistent cache path. Do not rely only on persist-credentials: false.

GitHub Actions jobs skipped when a needed job is skipped unless always() if condition official documentation

💡 Result:

According to official GitHub Actions documentation, a job that uses the needs keyword is dependent on its upstream jobs by default [1][2][3]. If any job in the dependency chain fails or is skipped, all downstream jobs that depend on it are automatically skipped [1][2][3]. To override this default behavior and allow a dependent job to run even if its upstream dependencies have failed or been skipped, you must include the always() conditional expression in the job-level if statement [1][2][3]. Key points regarding this behavior: 1. Default Dependency Logic: The needs keyword implies that all listed jobs must complete successfully [4][1][3]. A failure or skip in the upstream chain propagates downwards [5][6][1]. 2. Using always: When if: ${{ always() }} is specified for a job, it instructs GitHub Actions to execute that job after its dependencies have finished, regardless of their final status (success, failure, or skipped) [1][3]. 3. Granular Control: If you only want a job to run under specific outcomes (e.g., only if an upstream job was skipped, but not if it failed), you can combine always() with explicit status checks using the needs.<job_id>.result context [7][4][5]. For example: if: ${{ always && needs.my_job.result == 'skipped' }} Note that while always() ensures the job runs, it does not change the result status of the skipped upstream jobs themselves; it merely prevents the current job from being automatically skipped due to the upstream failure or skip [6].

Keep Dashmate package builds enabled for normal dispatches.

When only_drive is false and a workflow_dispatch tag does not start with npm-test:, build-npm and release-npm are skipped. release-dashmate-packages then skips because it needs release-npm, and the required js-build artifact is not produced. Use dependencies that run build-npm for normal dispatches and preserve NPM publish ordering for release events.

Final validation — Phase 1 + Phase 2

Verified the combined findings against head f9723d3. Three blocking issues remain: SDK cleanup skips stale outputs on warm caches, SDK release credentials reach shared persistent PR runners, and builder-controlled lifecycle scripts can execute in the hosted NPM publisher. Local reproductions confirmed the cleanup defect and Yarn's lifecycle behavior, including the rehearsal's early exit for already-published versions.

In `.github/workflows/release-kotlin-sdk.yml`:
- [BLOCKING] .github/workflows/release-kotlin-sdk.yml:165-167: Quote the cache exclusion so cleanup covers the working tree
  When target/ contains multiple entries, Bash expands the unquoted target/** before invoking Git. For example, target/debug and target/release produce `-e target/debug target/release`: the latter becomes a pathspec that restricts cleanup to the already-excluded target directory. A local reproduction returned success while leaving stale packages/ outputs untouched; quoting the pattern removed those outputs. Since checkout uses clean: false, this defeats the release cleanup guarantee. The Android build only cleans unwanted libraries within the ABIs it builds, so additional stale JNI ABI directories can survive into the AAR. Apply the same correction to release-swift-sdk.yml:118–120.
- [BLOCKING] .github/workflows/release-kotlin-sdk.yml:47-50: Keep release-write credentials off the shared PR runners
  This moves a contents: write job onto the persistent runner used by kotlin-sdk-build.yml, whose guard admits same-repository PRs and the thepastaclaw fork. Code or a compromised dependency executed in an admitted PR can persist a Git hook, Gradle initialization script, or modified user-local executable and execute again during a subsequent release. That execution can access the release token: the job explicitly supplies GH_TOKEN to several steps, and checkout also makes Git credentials available during the job. The later git reset/git clean does not sanitize .git/hooks or the runner's home directory. release-swift-sdk.yml:37–42 has the same exposure. This grants release-writing authority beyond the acknowledged acceptance of shared build-cache integrity. Use isolated release runners, or move credentialed attachment to a fresh hosted job; independently validate builder-provided checkout SHAs before executing them in privileged downstream jobs. Setting persist-credentials: false alone does not close this boundary.

In `.github/workflows/release.yml`:
- [BLOCKING] .github/workflows/release.yml:207-211: Prevent artifact-controlled scripts from executing in the NPM publisher
  The hosted publisher overlays the persistent builder's artifact onto packages/ without protecting tracked manifests or executable lifecycle inputs. The upload list is derived from the builder's mutable Git index, not a trusted allowlist: persisted PR code can remove packages/dashmate/package.json from that index during the build and include a replacement manifest containing a malicious prepack script. The publisher then reloads workspace manifests and runs Yarn npm publish with id-token: write. A local test using the checked-in Yarn 4.12.0 confirmed that prepack can read ACTIONS_ID_TOKEN_REQUEST_TOKEN, including during a dry run. Thus withholding OIDC permission from build-npm does not prevent builder code from obtaining publishing authority in the hosted job. Pack in the unprivileged job and publish the resulting tarballs without lifecycle execution, validating package identities and versions against trusted checkout metadata, or otherwise prevent artifact-controlled code from entering the credentialed execution path.
- [SUGGESTION] .github/workflows/release.yml:249: Exercise package assembly when rehearsing an existing release
  Yarn 4.12.0 processes --tolerate-republish before packing or running lifecycle scripts. If the registry already contains the version, it returns successfully even with --dry-run. Consequently, a rehearsal against an existing release such as v4.2.0-dev.7 can pass without exercising the hosted publisher's package assembly or prepack hooks. A local mock-registry test confirmed that the current flags skip prepack, while removing --tolerate-republish runs packing without publishing. Keep the flag for real publish retries, but omit it from the rehearsal.

These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.

For example, target/debug and target/release produce -e target/debug target/release: the latter becomes a pathspec that restricts cleanup to the already-excluded target directory. A local reproduction returned success while leaving stale packages/ outputs untouched; quoting the pattern removed those outputs. Since checkout uses clean: false, this defeats the release cleanup guarantee. The Android build only cleans unwanted libraries within the ABIs it builds, so additional stale JNI ABI directories can survive into the AAR. Apply the same correction to release-swift-sdk.yml:118–120.

🔴 Blocking: Keep release-write credentials off the shared PR runners

This moves a contents: write job onto the persistent runner used by kotlin-sdk-build.yml, whose guard admits same-repository PRs and the thepastaclaw fork. Code or a compromised dependency executed in an admitted PR can persist a Git hook, Gradle initialization script, or modified user-local executable and execute again during a subsequent release. That execution can access the release token: the job explicitly supplies GH_TOKEN to several steps, and checkout also makes Git credentials available during the job. The later git reset/git clean does not sanitize .git/hooks or the runner's home directory. release-swift-sdk.yml:37–42 has the same exposure. This grants release-writing authority beyond the acknowledged acceptance of shared build-cache integrity. Use isolated release runners, or move credentialed attachment to a fresh hosted job; independently validate builder-provided checkout SHAs before executing them in privileged downstream jobs. Setting persist-credentials: false alone does not close this boundary.

🔴 Blocking: Prevent artifact-controlled scripts from executing in the NPM publisher

The hosted publisher overlays the persistent builder's artifact onto packages/ without protecting tracked manifests or executable lifecycle inputs. The upload list is derived from the builder's mutable Git index, not a trusted allowlist: persisted PR code can remove packages/dashmate/package.json from that index during the build and include a replacement manifest containing a malicious prepack script. The publisher then reloads workspace manifests and runs Yarn npm publish with id-token: write. A local test using the checked-in Yarn 4.12.0 confirmed that prepack can read ACTIONS_ID_TOKEN_REQUEST_TOKEN, including during a dry run. Thus withholding OIDC permission from build-npm does not prevent builder code from obtaining publishing authority in the hosted job. Pack in the unprivileged job and publish the resulting tarballs without lifecycle execution, validating package identities and versions against trusted checkout metadata, or otherwise prevent artifact-controlled code from entering the credentialed execution path.

🟡 Suggestion: Exercise package assembly when rehearsing an existing release

Yarn 4.12.0 processes --tolerate-republish before packing or running lifecycle scripts. If the registry already contains the version, it returns successfully even with --dry-run. Consequently, a rehearsal against an existing release such as v4.2.0-dev.7 can pass without exercising the hosted publisher's package assembly or prepack hooks. A local mock-registry test confirmed that the current flags skip prepack, while removing --tolerate-republish runs packing without publishing. Keep the flag for real publish retries, but omit it from the rehearsal.
