WalkthroughThe test script now supports repeated executions and per-run logs. A new workflow provisions three MagicBlock stacks and runs repeated rock-paper-scissor settlement diagnostics with configurable repetition counts and artifact collection. ChangesRPS settlement diagnostics
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The new diagnostic workflow executes pull-request code after making a repository devnet keypair available on the runner and relies on mutable action and package references, which could expose or misuse the key and make validator behavior vary between runs; its pull-request repetition default also differs from the declared manual default. The PR is not merge-ready until these issues are fixed or explicitly accepted. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In @.github/workflows/diagnose-rps-settlement.yml:
- Line 70: Update the ephemeral-validator installation step to use a reviewed
exact package version instead of the mutable latest dist-tag, and change that
version intentionally when upgrading the validator binary.
- Line 24: Update the workflow job-name expression around matrix.stack so
pull_request runs use the declared default of 5 when inputs.runs_per_stack is
unavailable, while preserving explicit workflow_dispatch input values; apply the
same fallback consistently to both referenced expressions or reuse a shared
default.
- Line 33: Update every third-party GitHub Action reference in the workflow,
including actions/checkout and actions/upload-artifact, from mutable tags to
audited full commit SHAs. Preserve the corresponding version tags as trailing
comments, and ensure all four action usages are pinned consistently.

GitHub Actions official documentation inputs context available workflow_dispatch reusable workflows undefined context property empty string expression || fallback
💡 Result:
In GitHub Actions, when you access a nonexistent property in a context (such as an input that was not provided), it evaluates to an empty string ("") [1][2]. This behavior is fundamental to how fallback expressions function within the workflow syntax [3]. To implement a fallback mechanism for an input that might be undefined or empty, you can use the logical OR (||) operator [3]. For example, ${{ inputs.my_input || 'default_value' }} will evaluate to 'default_value' if inputs.my_input is an empty string [3]. Important technical considerations regarding this behavior include: 1. Empty String vs. Undefined: GitHub Actions does not distinguish between a property that is "missing" and one that is explicitly provided as an empty string; both result in an empty string in the expression context [4][5]. This means that if you define a default value in your workflow configuration, it may be bypassed if an empty string is passed during the workflow invocation [4][5]. 2. Reusable Workflows and workflow_dispatch: Since the unification of inputs for workflow_dispatch and reusable workflows (workflow_call), both trigger types populate the inputs context [6][7]. If you call a reusable workflow without specifying an optional input, it is passed as an empty string, not as a null or undefined value [4]. 3. Expression Fallback Syntax: The expression ${{ context.property || 'fallback' }} is the standard way to provide a default value [3]. Because an empty string is considered falsy in this context, the expression will correctly fallback to the value provided on the right side of the || operator [3]. 4. Conditional Logic: If you need to differentiate between an input being "not provided" and "provided as empty," the current architecture of GitHub Actions makes this difficult, as the runner often converts omitted inputs into empty strings before they reach the workflow [5]. A common workaround is to use an if conditional in a separate step or job to detect the empty state and set an environment variable dynamically [8].

Use the declared default for pull-request runs.
On pull_request, the inputs context is unavailable, so both expressions select 3. This conflicts with the declared workflow_dispatch default of 5. Change both fallbacks to 5, or define one shared default.

Pin every GitHub Action to a full commit SHA.
The workflow uses mutable references for four third-party actions. actions/upload-artifact runs after the workflow creates ~/.config/solana/id.json. Replace each tag with an audited full SHA and keep the version tag in a trailing comment.

Pin the ephemeral-validator package version.
npm install -g @magicblock-labs/ephemeral-validator@latest resolves the mutable npm latest dist-tag at job start. Different runs can therefore use different validator binaries. Install a reviewed exact version and update it intentionally.
